Background. The myeloid enzyme 12/15-lipoxygenase (LOX), which generates bioactive oxidized lipids, has been implicated in numerous inflammatory diseases, with several studies demonstrating an improvement in pathology in mice lacking the enzyme. However, the ability of 12/15-LOX to directly regulate B cell function has not been studied. Methods. The influence of 12/15-LOX on B cell phenotype and function, and IgM generation, was compared using wildtype (WT) and 12/15-LOX (Alox15(-/-)) deficient mice. The proliferative and functional capacity of splenic CD19(+) B cells was measured in vitro in response to various toll-like receptor agonists...

Looked-after children and young people (LACYP) are educationally disadvantaged compared to the general population. A systematic review was conducted of randomised controlled trials evaluating interventions aimed at LACYP aged ≤18 years. Restrictions were not placed on delivery setting or delivery agent. Intervention outcomes were: academic skills; academic achievement and grade completion; special education status; homework completion; school attendance, suspension, and drop-out; number of school placements; teacher-student relationships; school behaviour; and academic attitudes...

Aerosols emitted from metered dose inhalers (MDIs) are generally electrically charged and bipolar in nature. While a spacer can effectively dampen the charge magnitude of aerosols, the electrostatic interactions between the positively and negatively charged particles and the spacer have not yet been characterized separately. The Bipolar Charge Analyzer (BOLAR) was employed to investigate interactions between the spacer and the charged aerosols. Three individual actuations of Tilade(®) MDI were introduced without a spacer and through an anti-static AeroChamber Plus® Z Stat(®), an uncoated and a detergent-coated AeroChamber Plus(®) spacer into the BOLAR at 60 L/min...

Philip A Storm, Dominik A Herbst, Timm Maier, Craig A Townsend
Fungal polyketide synthases (PKSs) are large, multidomain enzymes that biosynthesize a wide range of natural products. A hallmark of these megasynthases is the iterative use of catalytic domains to extend and modify a series of enzyme-bound intermediates. A subset of these iterative PKSs (iPKSs) contains a C-methyltransferase (CMeT) domain that adds one or more S-adenosylmethionine (SAM)-derived methyl groups to the carbon framework. Neither the basis by which only specific positions on the growing intermediate are methylated ("programming") nor the mechanism of methylation are well understood...

OBJECTIVE: All women with CHD, especially those with more severe disease, should be offered preconception counseling (PCC), to discuss the risk of complications and to plan a future pregnancy. Several scoring system have been devised to estimate the risk of adverse events in pregnancies complicated by maternal heart disease (HD) and while comparisons have been made across the whole population, none have focused on the high-risk population. METHODS: Retrospective cohort study that included women classed as modified WHO (mWHO) 3 and 4 who had a pregnancy from at least 20weeks gestation between 1994 and 2015 managed within our institution...

Barrow's goldeneyes are sea ducks that winter throughout coastal British Columbia (BC). Their diet consists primarily of intertidal blue mussels, which can accumulate PAHs; accordingly, goldeneyes may be susceptible to exposure through contaminated prey. In 2014/15, we examined total PAH concentrations in mussels from undeveloped and developed coastal areas of BC. At those same sites, we used EROD to measure hepatic CYP1A induction in goldeneyes. We found higher mussel PAH concentrations at developed coastal sites...

Serious mental illness (SMI) is disabling, and current interventions are ineffective for many. This exploratory study sought to demonstrate the feasibility of applying topological data analysis (TDA) to resting-state functional connectivity data obtained from a heterogeneous sample of 235 adult inpatients to identify a biomarker of treatment response. TDA identified two groups based on connectivity between the prefrontal cortex and striatal regions: patients admitted with greater functional connectivity between these regions evidenced less improvement from admission to discharge than patients with lesser connectivity between them...

Particulate matter (PM) measurements were conducted during heating corn oil, heating corn oil mixed with the table salt and heating low fat ground beef meat using a PTFE-coated aluminum pan on an electric stove with low ventilation. The main objectives of this study were to measure the size segregated mass concentrations, emission rates, and fluxes of 24 trace elements emitted during heating cooking oil or oil with salt and cooking meat. Health risk assessments were performed based on the resulting exposure to trace elements from such cooking activities...

RATIONALE: Past research has found that exposure to alcohol cues causes a narrowing of attentional scope and enhances the neural responses associated with approach motivation. OBJECTIVE: The current research sought to determine if a manipulated broadened (global) attentional scope would reduce approach-motivated neural reactivity to alcohol pictures. METHODS: In the current study, participants (n = 82) were exposed to alcohol and neutral pictures following either a global or local attentional scope manipulation...

BACKGROUND: Best practice in dialysis is synthesised in clear international guidelines. However, a large gap remains between the international guidelines and the actual delivery of care. In this paper, we report outcomes for the first year of a multifaceted dialysis improvement programme in our network. METHODS: One year collaborative involving 3 haemodialysis units and a peritoneal dialysis (PD) programme involving 299 dialysis patients. Each unit addressed a different indicator (unit A - catheter-related bloodstream infection [CRBSI], unit B - pre-dialysis blood pressure [BP], unit C - dialysis dose, unit D - anaemia) with a shared aim to match the top 10% in the UK...

Impaired insight into illness (IMP-INS) is common among individuals with schizophrenia spectrum disorders (SSD), contributing to medication nonadherence and poor clinical outcomes. Caloric vestibular simulation (CVS) is typically used to assess peripheral vestibular system function. Left cold CVS is also a transiently effective treatment for IMP-INS and hemineglect secondary to right brain hemisphere stroke, and possibly for IMP-INS and mood stabilization in patients with SSD. Participants with SSD and moderate-to-severe IMP-INS participated in an exploratory double blind, crossover, randomized controlled study of the effects of CVS on IMP-INS...

REVIEW
Nick van Es, Philip S Wells, Marc Carrier
Patients with unprovoked venous thromboembolism (VTE) should receive anticoagulant treatment for at least 3 to 6months. Thereafter, the decision to extend treatment indefinitely for secondary prevention of recurrent events is based on a personalized assessment of the risks of recurrent VTE and anticoagulant-related bleeding. Whereas there are clinical factors that identify patients at higher risk of recurrent VTE, factors to aid the prediction of major bleeding events during anticoagulant therapy have received much less attention...

BACKGROUND: Neuroimaging studies of attention-deficit/hyperactivity disorder (ADHD) have most commonly reported volumetric abnormalities in the basal ganglia, cerebellum, and prefrontal cortices. Few studies have examined the relationship between ADHD symptomatology and brain structure in population-based samples. We investigated the relationship between dimensional measures of ADHD symptomatology, brain structure, and reaction time variability-an index of lapses in attention. We also tested for associations between brain structural correlates of ADHD symptomatology and maps of dopaminergic gene expression...

OBJECTIVES: Australia's universal health insurance system Medicare generates very large amounts of data on out-of-pocket expenditure (OOPE), but only highly aggregated statistics are routinely published. Our primary purpose is to develop indices from the Medicare administrative data to quantify changes in the level and distribution of OOPE on out-of-hospital medical services over time. METHODS: Data were obtained from the Australian Hypertension and Absolute Risk Study, which involved patients aged 55 years and over (n=2653)...

In this study, we used the pilocarpine model of epilepsy to evaluate the involvement of calpain dysregulation on epileptogenesis. Detection of spectrin breakdown products (SBDPs, a hallmark of calpain activation) after induction of pilocarpine-induced status epilepticus (SE) and before appearance of spontaneous seizure suggested the existence of sustained calpain activation during epileptogenesis. Acute treatment with the cell permeable inhibitor of calpain, MDL-28170, resulted in a partial but significant reduction on seizure burden...

The aims of this research were to report characteristics of rescued cats at a secondary emergency animal shelter in Fukushima prefecture, Japan, and evaluate how adoptability, stress level, upper respiratory infection (URI) syndrome incidence, and URI pathogen prevalence were associated with the cat's shelter intake source and shelter characteristics. All cats admitted to the Miharu shelter, Fukushima Prefecture from 2012 to 2014 were included in the study. The results demonstrate that in situ corticosteroid and antibiotic use were associated with cats subsequently developing upper respiratory infections (URI)...
