The aims of this review are to gather and systematize the currently available evidence on the effect of the threat of eviction on health and its eventual spillover effects, to assess the quality of the selected studies, and to describe how these findings vary with respect to dimensions of social inequity. We conducted a literature search in March 2016, which yielded 2208 unduplicated articles. The title, abstract and full text of these articles were reviewed by three independent pairs of researchers. We performed a quality assessment of each article, and evaluated whether health inequities had been considered...

Every year numerous protein engineering and directed evolution studies are published, increasing the knowledge which could be used by protein engineers. Here we test a protein engineering strategy that allows quick access to improved biocatalysts with very little screening effort. Conceptually it is assumed that engineered residues, previously identified by rational and random methods, induce similar improvements when transferred to family members. Applied to ene-reductases from the Old Yellow Enzyme family (OYE), the newly created variants were tested with three compounds revealing more stereocomplementary OYE pairs with potent turnover frequencies (up to 660 h-1) and excellent stereoselectivities (up to >99%)...

Over the past few years, treatment options for chronic hepatitis C virus (HCV) infection have evolved dramatically. The current approved interferon-free direct-acting antiviral (DAA) regimens have been shown to be safe and effective with sustained virologic response (SVR) rates of >90% in most patients. Unique issues yet remain such as the challenges in patients with impaired renal function or decompensated cirrhosis. Patients with stage 4-5 chronic kidney disease (CKD) have a higher prevalence of HCV infection compared with the general population...

BACKGROUND: The interleukin-17 (IL-17) cytokine pathway plays a key role in the development of psoriasis. Antibodies targeting IL-17 or blocking its receptor may be a new therapeutic approach for psoriasis. To assist treatment selection in daily practice it is essential to understand the benefit and risk profile of IL-17 antagonists. OBJECTIVE: We performed a meta-analysis to evaluate the efficacy and safety of IL-17 antagonists in patients with psoriasis. METHODS: We searched a number of databases for relevant randomized clinical trials (RCTs) published before May 2016...

REVIEW
Charles S Wiysonge, Hazel A Bradley, Jimmy Volmink, Bongani M Mayosi, Lionel H Opie
BACKGROUND: Beta-blockers refer to a mixed group of drugs with diverse pharmacodynamic and pharmacokinetic properties. They have shown long-term beneficial effects on mortality and cardiovascular disease (CVD) when used in people with heart failure or acute myocardial infarction. Beta-blockers were thought to have similar beneficial effects when used as first-line therapy for hypertension. However, the benefit of beta-blockers as first-line therapy for hypertension without compelling indications is controversial...

Jakob Ödén, Kjell Eriksson, Iuliana Toma-Dasu
PURPOSE: A constant relative biological effectiveness (RBE) of 1.1 is currently used in proton radiation therapy to account for the increased biological effectiveness compared to photon therapy. However, there is increasing evidence that proton RBE vary with the linear energy transfer (LET), the dose per fraction and the type of the tissue. Therefore, this study aims to evaluate the impact of disregarding variations in RBE when comparing proton and photon dose plans for prostate treatments for various fractionation schedules using published RBE models and several α/β assumptions...

The scientific articles and Indoor Air conference publications of the indoor air sciences (IAS) during the last 50 years are summarized. In total 7524 presentations, from 79 countries, have been made at Indoor Air conferences held between 1978 (49 presentations) and 2014 (1049 presentations). In the Web of Science 26,992 articles on indoor air research (with the word "indoor" as a search term) have been found (as of 1 Jan 2016) of which 70% were published during the last 10 years. The modern scientific history started in the 1970s with a question: "did indoor air pose a threat to health as did outdoor air?" Soon it was recognized that indoor air is more important, from a health point of view, than outdoor air...

The feline immunodeficiency virus (FIV) is a retrovirus of the Lentivirus genus that was initially isolated from a colony of domestic cats in California in 1986 and has now been recognized as a common feline pathogen worldwide. To date, there is only one recent serology-based report on FIV in mainland China which was published in 2016. We designed this study to investigate the molecular prevalence and diversity of feline immunodeficiency virus (FIV) in domestic cats from mainland China. We studied the prevalence of FIV in whole blood samples of 615 domestic cats in five cities (Beijing, Guangzhou, Nanjing, Shanghai and Yangzhou) of mainland China and examined them using FRET-PCR (Fluorescence Resonance Energy Transfer-Polymerase Chain Reaction) and regular PCRs for the gag and env genes...

Angiopoietin-like protein 4 (ANGPTL4) is suggested to be a master regulator of plasma triglyceride metabolism. Our aim was to study whether the previously reported high levels of ANGPTL4 detected in serum from patients with rheumatoid arthritis (RA) by ELISA was due to any specific molecular form of this protein (oligomers, monomers or fragments). ANGPTL4 levels were first determined in serum from 68 RA patients and 43 age and sex matched control subjects and the mean values differed by a factor of 5.0. Then, ANGPTL4 was analyzed after size exclusion chromatography (SEC) of serum samples...

Currently, the overall incidence and risk of infections with epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) in non-small-cell lung cancer (NSCLC) patients remained undetermined. We searched Pubmed for related articles published from 1 January 1990 to 31 November 2015. Eligible studies included prospective randomized controlled trials (RCTs) evaluating therapy with or without EGFR-TKIs in patients with NSCLC. Data on infections were extracted. Pooled incidence, Peto odds ratio (Peto OR), and 95% confidence intervals (CIs) were calculated...

This article examines U.S. homophile magazine contributions from and representations of Canada from 1953 to 1964. Drawing on 240 articles, letters, and other items that were published in ONE, Mattachine Review, and The Ladder, the essay first reviews Canadian-authored materials and then shows that U.S. gay and lesbian movement periodicals depicted Canada as more sexually conservative than the United States in three ways and more sexually liberal in one way. The magazines presented Canada as more sexually conservative in its failure to develop an organized gay and lesbian movement, its policies and practices of sexual censorship, and its opposition to progressive homosexual law reform...

In this work, the triplet state delocalization in a series of monodisperse oligo(p-phenyleneethynylene)s (OPEs) is studied by pulsed electron paramagnetic resonance (EPR) and pulsed electron nuclear double resonance (ENDOR) determining zero-field splitting, optical spin polarization, and proton hyperfine couplings. Neither the zero-field splitting parameters nor the optical spin polarization change significantly with OPE chain length, in contrast to the hyperfine coupling constants, which showed a systematic decrease with chain length n according to a 2/(1+n) decay law...

Since the 1990s, a large body of literature has been published regarding minimally invasive coronary artery bypass grafting. Varying techniques, complexity of the procedures and the necessity of patient selection have led to its inconsistent application. We describe the standardized technique of left internal mammary artery grafting to the left anterior descending coronary artery, off-pump through a left inferior J-hemisternotomy (JOPCAB). This approach is straightforward, safe, effective, and replicable in virtually all patients...

We propose a resilient cache replacement approach based on a Value of sensed Information (VoI) policy. To resolve and fetch content when the origin is not available due to isolated in-network nodes (fragmentation) and harsh operational conditions, we exploit a content caching approach. Our approach depends on four functional parameters in sensory Wireless Body Area Networks (WBANs). These four parameters are: age of data based on periodic request, popularity of on-demand requests, communication interference cost, and the duration for which the sensor node is required to operate in active mode to capture the sensed readings...
