BACKGROUND: As medical schools strive to improve the learning environment, it is important to understand medical students' perceptions of mistreatment. The purpose of this study was to explore student interpretations of previously reported mistreatment incidents to better understand how they conceptualise the interactions. METHODS: Medical students were presented with case scenarios of previously reported instances of mistreatment and asked to indicate their agreement as to whether the scenarios demonstrated mistreatment, using a five-point Likert scale (1, strongly disagree; 5, strongly agree)...

AIM AND OBJECTIVE: Regulation of microRNA gene expression by DNA methylation may represent a key mechanism to drive cardiac fibrosis progression. Cardiac fibroblast autophagy is the primary source of cardiac fibrosis, but the mechanisms underlying this process are incompletely understood. Here we found that DNMT3A suppression of the microRNA-200b (miR-200b) through pathway leads to cardiac fibroblast autophagy in cardiac fibrosis. METHODS: To understand the impact of DNMT3A on miR-200b at cardiac fibrosis, the rat cardiac fibrosis model was established via the abdominal aortic coarctation...

BACKGROUND: Endovascular treatment offers an alternative less-invasive approach to open repair for subclavian artery atherosclerotic disease (SAAD). However, only few studies compared the outcomes of both strategies in the long run. This study reports on the performance of endovascular and surgical revascularization for SAAD. METHODS: A retrospective review was conducted on patients treated for SAAD at two institutions between January 1998 and December 2015. Primary outcome of this study was the composite endpoint of re-intervention-free survival (RFS) defined as time to re-intervention and/or death from any cause...

Ammonium and diphenhydramine are active ingredients commonly found in the same pharmaceutical preparations. We report for the first time a sub-minute method for the simultaneous determination of ammonium and diphenhydramine. The method is based on capillary electrophoresis with capacitively coupled contactless conductivity detection. Both analytes can be quantified in a single run (∼80 injections h-1 ) using 30 mmol L-1 2-(N-morpholino)ethanesulfonic acid and 15 mmol L-1 lithium hydroxide (pH = 6.0) as a background electrolyte...

Species of the ant genus Polyergus are social parasites that steal brood from colonies of their hosts in the closely related genus Formica. Upon emergence as adults in a mixed population, host Formica workers carry out all the normal worker functions within the Polyergus colony, including foraging, feeding, grooming, and rearing brood of the parasitic Polyergus ants. Some unmated Polyergus gynes (queens) run in the raiding columns of their colonies and attract males by releasing a pheromone from their mandibular glands...

BACKGROUND AND OBJECTIVES: First-order conditional estimation with interaction (FOCEI) is one of the most commonly used estimation methods in nonlinear mixed effects modeling, while the stochastic approximation expectation maximization (SAEM) is the newer estimation algorithm. This work aimed to compare the performance of FOCEI and SAEM methods when using NONMEM® with the classical one- and two-compartment models across rich, medium, and sparse data. METHODS: One- and two-compartment models of the previous studies were used to simulate data in three scenarios: rich, medium, and sparse data...

Necrotizing autoimmune myopathy is characterized by predominant muscle fiber necrosis and regeneration with little or no inflammation. We describe a 58-year-old woman with previous breast cancer and statin use who complained of rapidly progressive weakness of lower limbs without pain, making walking, running and climbing stairs difficult. The creatine kinase level was 2,843 U/L, and muscle biopsy showed a dystrophic pattern. The genetic test for muscular dystrophies was negative and for anti-3-hydroxy-3-methylglutaryl coenzyme A reductase was positive...

Can hazard perception testing be useful for the emergency services? Previous research has found emergency response drivers' (ERDs) to perform better than controls, however these studies used clips of normal driving. In contrast, the current study filmed footage from a fire-appliance on blue-light training runs through Nottinghamshire, and endeavoured to discriminate between different groups of EDRs based on experience and collision risk. Thirty clips were selected to create two variants of the hazard perception test: a traditional push-button test requiring speeded-responses to hazards, and a prediction test that occludes at hazard onset and provides four possible outcomes for participants to choose between...

Primary hemifacial spasm with few exceptions is due to the vascular compression of the facial nerve that can be evidenced with high resolution MRI. Microvascular decompression is the only curative treatment for this pathology. According to literature review detailed in chapter "conflicting vessels", the compression is located at the facial Root Exit Zone (REZ) in 95% of the cases, and in 5% distally at the cisternal or the intrameatal portion of the root as the sole conflict or in addition to one at brainstem/REZ...

There is currently a lack of research investigating the effectiveness of commercial broiler enrichments, and in particular the ability of these additions to create opportunities for positive welfare. One aim of this study was to investigate whether offering broiler chickens enrichments that have recently been found to be preferred leads to increased levels of activity. A second aim was to investigate the emotional effects of provision of these enrichments by assessing levels of fearfulness and play-like activity...

We report a comprehensive characterization of a 10 at.% Yb3+ -doped YSAG (Yb:Y₃Scx Al(5-x) O12 , x = 1.5) ceramic, including microstructural, spectroscopic and laser properties. Moreover, we illustrate and discuss the fabrication technique. Yb3+ in YSAG features a broader absorption and emission band than in traditional YAG, which is advantageous for laser applications (i.e., tunable laser sources, ultrafast pulse generation). Pumping in a quasi continuous wave regime at 936 nm, the ceramic has shown good laser performance as the maximum output power was 6...

Self-driving vehicles (SDVs) promise to considerably reduce traffic crashes. One pressing concern facing the public, automakers, and governments is "How safe is safe enough for SDVs?" To answer this question, a new expressed-preference approach was proposed for the first time to determine the socially acceptable risk of SDVs. In our between-subject survey (N = 499), we determined the respondents' risk-acceptance rate of scenarios with varying traffic-risk frequencies to examine the logarithmic relationships between the traffic-risk frequency and risk-acceptance rate...
