BACKGROUND: Skin microvascular responses to local heating are frequently used to assess microvascular function. Several local heating protocols have been developed, all varying slightly in execution. The aim of this study was to determine the inter-day reproducibility of the four most commonly used local heating protocols in healthy young subjects. METHODS: Fifteen, healthy males (28±5yrs, BMI 25±2kg/m(2)) attended two experimental trials 2-7days apart. During each trial, baseline and maximal thermally stimulated forearm skin responses were examined simultaneously at four sites on the dominant forearm using laser Doppler flowmetry (LDF)...

Genetic conflict between viruses and their hosts drives evolution and genetic innovation. Prokaryotes evolved CRISPR-mediated adaptive immune systems for protection from viral infection, and viruses have evolved diverse anti-CRISPR (Acr) proteins that subvert these immune systems. The adaptive immune system in Pseudomonas aeruginosa (type I-F) relies on a 350 kDa CRISPR RNA (crRNA)-guided surveillance complex (Csy complex) to bind foreign DNA and recruit a trans-acting nuclease for target degradation. Here, we report the cryo-electron microscopy (cryo-EM) structure of the Csy complex bound to two different Acr proteins, AcrF1 and AcrF2, at an average resolution of 3...

Introduction: Like other forms of drug dependence, tobacco dependence is increasingly being described as a "chronic brain disease." The potential consequences of this medical labelling have been examined in relation to other addictions, but the implications for tobacco control have been neglected. Some have posited that biomedical conceptions of addiction will reduce stigma and increase uptake of efficacious treatments. Others have countered that it could increase stigma, reduce treatment seeking, and deter unassisted quitting...

Major health policy creation or changes, including governmental and private policies affecting health care delivery are based on health care reform(s). Health care reform has been a global issue over the years and the United States has seen proposals for multiple reforms over the years. A successful, health care proposal in the United States with involvement of the federal government was the short-lived establishment of the first system of national medical care in the South. In the 20th century, the United States was influenced by progressivism leading to the initiation of efforts to achieve universal coverage, supported by a Republican presidential candidate, Theodore Roosevelt...

OBJECTIVES: The 28-Joint Disease Activity Score (DAS28) using C-reactive protein (CRP) and DAS28 using erythrocyte sedimentation rate (DAS28-ESR) may not be interchangeable. We sought to compare and estimate optimal thresholds for the DA28-CRP for use in early rheumatoid arthritis (ERA). METHODS: Patients from the Canadian Early Arthritis Cohort with baseline and 12 months' data for both DAS28-ESR and DAS28-CRP were examined for correlations and differences between DAS28-CRP and DAS28-ESR across their range of values...

Habronematid nematodes were collected from the stomachs of donkeys, Equus asinus L., in the Tarim Basin, Xinjiang, China. After examination by light and scanning electron microscopy, Habronema muscae (Carter, 1861) and H. majus (Creplin, 1849) were identified. The morphology of our specimens representing H. muscae (Carter, 1861) agreed well with previous redescriptions in the shape of the lateral lips, origin of the lateral alae, ratio of left and right spicules, and number and arrangement of caudal papillae...

BACKGROUND: Many dynamics in the relationship among military service-related disabilities, health care benefits, mental health disorders, and post-deployment homelessness among US Veterans are not well understood. OBJECTIVES: Determine whether Veterans with a disability-related discharge from military service are at higher risk for homelessness, whether Veterans Health Administration (VHA) service-connected disability benefits mitigates that risk, and whether risks associated with discharge type, service-connected disability, or the interaction between them vary as a function of mental health disorders...

OBJECTIVE: Evidence regarding the age at which autism spectrum disorder (ASD) is identified is essential for improving early detection, yet many extant studies have not applied time-to-event analyses, which account for statistical biases that arise from sampling in cross-sectional surveys by adjusting for child age at time of parental report. Our objective was to estimate age distributions for first identification of ASD in national parent surveys using time-to-event analyses. METHOD: We conducted time-to-event analyses of responses to identical questions in the 2011 to 2012 National Survey of Children's Health (n = 95,677) and the 2009 to 2010 National Survey of Children with Special Health Care Needs (n = 371,617)...

The proper development and function of skeletal muscle is vital for health throughout the lifespan. Skeletal muscle function enables posture, breathing, and locomotion; and also impacts systemic processes-such as metabolism, thermoregulation, and immunity. Diseases of skeletal muscle (myopathies, muscular dystrophies) and even some neurological, age-related, and metabolic diseases compromise muscle function and negatively affect health span and quality of life. There have been numerous, recent examples of studies on skeletal muscle development with exciting, therapeutic implications for muscle diseases...

Few secondary metabolites have been reported from mammalian microbiome bacteria despite the large numbers of diverse taxa that inhabit warm-blooded higher vertebrates. As a means to investigate natural products from these microorganisms, an opportunistic sampling protocol was developed, which focused on exploring bacteria isolated from roadkill mammals. This initiative was made possible through the establishment of a newly created discovery pipeline, which couples laser ablation electrospray ionization mass spectrometry (LAESIMS) with bioassay testing, to target biologically active metabolites from microbiome-associated bacteria...

KIAA0319 is a transmembrane protein associated with dyslexia with a presumed role in neuronal migration. Here we show that KIAA0319 expression is not restricted to the brain but also occurs in sensory and spinal cord neurons, increasing from early postnatal stages to adulthood and being downregulated by injury. This suggested that KIAA0319 participates in functions unrelated to neuronal migration. Supporting this hypothesis, overexpression of KIAA0319 repressed axon growth in hippocampal and dorsal root ganglia neurons; the intracellular domain of KIAA0319 was sufficient to elicit this effect...

BACKGROUND AND PURPOSE: Interventions are needed to improve stroke literacy among recent stroke survivors. We developed an educational video for patients hospitalized with acute ischemic stroke (AIS) and intracerebral hemorrhage (ICH). METHODS: A 5-minute stroke education video was shown to our AIS and ICH patients admitted from March to June 2015. Demographics and a 5-minute protocol Montreal Cognitive Assessment were also collected. Questions related to stroke knowledge, self-efficacy, and patient satisfaction were answered before, immediately after, and 30 days after the video...

Conventional wisdom suggests that assessment length is positively related to the rate at which applicants opt out of the assessment phase. However, restricting assessment length can negatively impact the utility of a selection system by reducing the reliability of its construct scores and constraining coverage of the relevant criterion domain. Given the costly nature of these tradeoffs, is it better for managers to prioritize (a) shortening assessments to reduce applicant attrition rates or (b) ensuring optimal reliability and validity of their assessment scores? In the present study, we use data from 222,772 job-seekers nested within 69 selection systems to challenge the popular notion that selection system length predicts applicant attrition behavior...

The purpose of our work was to identify imaging features of atypical apocrine lesions and determine the rate of upgrade to ductal carcinoma in situ (DCIS) or invasive carcinoma at excision after such a diagnosis on percutaneous breast biopsy. From January 1, 2006, through October 8, 2013, a total of 33,157 breast core biopsies were performed at University of Pittsburgh Medical Center. Of those, 58 (0.2%) showed atypical apocrine lesions. For 24, atypical apocrine adenosis (AAA) or atypical apocrine metaplasia (AAM) was the only risk lesion, with no known ipsilateral malignancy, and the results of excision were available...
