Hepatitis C virus (HCV) is a positive-sense single-stranded RNA virus with an estimated infection in ∼180 million people worldwide, and its chronic infection leads to development of cirrhosis and hepatocellular carcinoma. Although recent development of direct acting antiviral (DAA) compounds improved anti-HCV regimens, alternative therapeutic compounds are still demanded due to an expected emergence of escape mutants for those DAAs. In order to identify novel anti-HCV agents, we conducted chemical library screening for 2,086 compounds using HCV Rep-Feo reporter replicon in Huh7 hepatoma cells...

QUESTION UNDER STUDY: In Switzerland, summer 2015 was the second warmest summer for 150 years (after summer 2003). For summer 2003, a 6.9% excess mortality was estimated for Switzerland, which corresponded to 975 extra deaths. The impact of the heat in summer 2015 in Switzerland has not so far been evaluated. METHODS: Daily age group-, gender- and region-specific all-cause excess mortality during summer (June-August) 2015 was estimated, based on predictions derived from quasi-Poisson regression models fitted to the daily mortality data for the 10 previous years...

BACKGROUND: In many countries, those with lower socioeconomic status are disproportionately affected by poor oral health. This can be attributed, at least in part, to differences in preventive dental visiting. While several theories have been applied to the area, they generally fail to capture the recursive nature of dental visiting behaviour, and fall short of informing the design of complex interventions to tackle inequalities. OBJECTIVE: To undertake a systematic review and synthesis of theory in order to provide an overview of the pathways which bring about socioeconomic inequalities in early dental visiting, and identify possible intervention points...

Kazuhiro Tanaka, Yasuhiko Watari
The onion fly Delia antiqua advances its eclosion timing with decreasing temperature amplitude to compensate for a depth-dependent phase delay of the zeitgeber. To elucidate whether or not naturally occurring day-to-day variations in the amplitude of soil temperature cycle disturb this compensatory response, we monitored daily variations in the temperature amplitude in natural soils and evaluated the impact on adult eclosion timing. Our results indicated that both median and variance of the soil temperature amplitude become smaller as depth increases...

Building on our previous work (J. Phys. Chem. C, 2016, 120, 16561), using an empirical model we run both classical and path-integral molecular dynamics simulations for a type II clathrate hydrate containing different amounts of guest H2 molecules from 1 to 5 molecules per large cage, with results presented at temperatures of 50, 100 K and 200 K. We present results for the density isosurfaces of the guest molecules at all different occupations and temperatures, showing how the density approaches the perfect tetrahedral structure which has been found for the n = 4 case in which each molecule sits on the vertex of a tetrahedron about the centre of each large cage...

The rapid growth in the number of behavior analysts and aspiring behavior analysts creates an imperative for effective and efficient supervisory practices. Many behavior analysts receive little to no explicit instruction and mentoring in supervision practices while they are in training themselves. Those behavior analysts may then be expected to provide supervision for a range of individuals soon after graduation and certification and throughout the remainder of their career. The papers included in this special issue offer guidance for establishing and maintaining supervisory relationships, understanding the importance of each of the ethical guidelines for supervision, structuring group supervision experiences, managing problems that can arise during the course of a supervisory relationship, and arranging models of supervision within human service organizations...

The impact of the combined effects of heat stress, increased vapor pressure deficit (VPD) and water deficit on the physiology of major crops needs to be better understood to help identifying the expected negative consequences of climate change and heat waves on global agricultural productivity. To address this issue, rice, wheat, and maize plants were grown under control temperature (CT, 25°C, VPD 1.8 kPa), and a high temperature (HT, 38°C, VPD 3.5 kPa), both under well-watered (WW) and water deficit (WD) conditions...

Nano-hydroxyapatite/polyamide 66 (nHA/PA66) porous scaffolds were fabricated by a phase inversion method. Carbon nanotubes (CNTs) and silk fibroin (SF) were used to modify the surface of the nHA/PA66 scaffolds by freeze-drying and cross-linking. Dexamethasone was absorbed to the CNTs to promote the osteogenic differentiation of bone mesenchymal stem cells (BMSCs). The cell viability of BMSCs was investigated by changing the concentration of the CNT dispersion, and the most biocompatible scaffold was selected...

Brittany J Carr, William K Stell
Myopia is the most common childhood refractive disorder. Atropine inhibits myopia progression, but its mechanism is unknown. Here, we show that myopia-prevention by atropine requires production of nitric oxide (NO). Form-deprivation myopia (FDM) was induced in week-old chicks by diffusers over the right eye (OD); the left eye (OS) remained ungoggled. On post-goggling days 1, 3, and 5, OD received intravitreally 20 µL of phosphate-buffered saline (vehicle), or vehicle plus: NO source: L-arginine (L-Arg, 60-6,000 nmol) or sodium nitroprusside (SNP, 10-1,000 nmol); atropine (240 nmol); NO inhibitors: L-NIO or L-NMMA (6 nmol); negative controls: D-Arg (10 µmol) or D-NMMA (6 nmol); or atropine plus L-NIO, L-NMMA, or D-NMMA; OS received vehicle...

Life-history traits are generally assumed to be inherited quantitatively. Fishing that targets large, old individuals is expected to decrease age at maturity. In Atlantic salmon (Salmo salar), it has recently been discovered that sea age at maturity is under strong control by a single locus with sexually dimorphic expression of heterozygotes, which makes it less intuitive to predict how life histories respond to selective fishing. We explore evolutionary responses to fishing in Atlantic salmon, using eco-evolutionary simulations with two alternative scenarios for the genetic architecture of age at maturity: (i) control by multiple loci with additive effects and (ii) control by one locus with sexually dimorphic expression...

The aim of the present review is to consider the clinical relevance of individualized blood pressure (BP) goal under treatment in hypertensive patients according to their age, comorbidities or established cardiovascular (CV) disease. Evidence from large-scale randomized trials to support a lower BP goal, as initially recommended by guidelines in high-risk hypertensive patients, were lacking. Recently, the randomized intervention SPRINT trial studied two treatment targets for systolic BP (120mm Hg versus 140mm Hg in the intensive and standard treatment group, respectively) among high-risk hypertensive patients, without diabetes and without a history of prior stroke...

: Pain acceptance is a robust predictor of adjustment to chronic pain; however, the dynamics of pain acceptance in daily life are largely unexamined. Furthermore, research on pain acceptance in those with pain and physical disability is needed. To examine pain acceptance in daily life, we collected 7 days of ecological momentary assessments of pain intensity and pain interference (5X/day) with continuous accelerometry (physical activity) in 128 individuals with chronic pain and spinal cord injury...

The kidney allocation system that took effect on December 4, 2014 represents a significant improvement over the prior approach. It seeks to improve outcomes by longevity matching - pairing kidneys expected to function the longest with recipients expected to live the longest. It addresses the biological barriers faced by highly sensitized patients in an evidence based fashion and it begins to introduce the concept of medical need into kidney allocation by crediting time from the starting dialysis to a patient's waiting time...

Micropollutants enter surface waters through various pathways, of which wastewater treatment plants (WWTPs) are a major source. The large diversity of micropollutants and their many modes of toxic action pose a challenge for assessing environmental risks. In this study, we investigated the potential impact of WWTPs on receiving ecosystems by describing concentration patterns of micropollutants, predicting acute risks for aquatic organisms and validating these results with macroinvertebrate biomonitoring data...

This study adopts social capital theory and transaction cost theory to explore the feasibility of an inter-organizational cross-hospital electronic medical records (EMR) exchange system, and the factors that affect its adoption. The concept of value co-creation is also used to assess such a system, and its influence on the performance of participating medical institutes. This research collected 330 valid paper-based questionnaires from the medical staff of various institutes. The results showed that social interaction ties and shared vision positively affected medical institutes' willingness to adopt the EMR exchange system, while asset specificity and uncertainty increased the related transaction costs...
