Understanding the immediate and longer-term effects of transportation and re-housing in a laboratory species is crucial in order to refine the transfer process, enable the optimal introduction of new animals to a novel environment and to provide a sufficient acclimatisation period before usage. Whilst consideration of animal welfare in most model vertebrate species has received attention, little quantitative evidence exists for the optimal care of the common laboratory amphibian Xenopus laevis. Techniques for the non-invasive welfare assessment of amphibians are also limited and here a non-invasive physiological assay was developed to investigate the impacts of transportation, transport medium and re-housing on X...

Pools are common in northern peatlands but studies have seldom focused on their nutrient biogeochemistry, especially in relation to their morphological characteristics and through seasons. We determined the environmental characteristics controlling carbon (C), nitrogen (N) and phosphorus (P) biogeochemistry in pools and assessed their evolution over the course of the 2016 growing season in a subboreal ombrotrophic peatland of eastern Canada. We showed that water chemistry variations in 62 pools were significantly explained by depth (81...

BACKGROUND: Cardiovascular disease (CVD) is a leading cause of post-liver transplant death, and variable care patterns may affect outcomes. We aimed to describe epidemiology and outcomes of inpatient CVD care across U.S. hospitals. METHODS: Using a merged dataset from the 2002-2011 Nationwide Inpatient Sample and the American Hospital Association Annual Survey, we evaluated liver transplant patients admitted primarily with myocardial infarction (MI), stroke (CVA), congestive heart failure (CHF), dysrhythmias, cardiac arrest (CA), or malignant hypertension...

PROBLEM/CONDITION: Doctor-diagnosed arthritis is a common chronic condition affecting an estimated 23% (54 million) of adults in the United States, greatly influencing quality of life and costing approximately $300 billion annually. The geographic variations in arthritis prevalence, health-related characteristics, and management among states and territories are unknown. Therefore, public health professionals need to understand arthritis in their areas to target dissemination of evidence-based interventions that reduce arthritis morbidity...

Introduction: In the absence of a vaccine, there is an urgent need for the identification of effective agents that prevent HIV transmission in uninfected individuals. Non-vaccine Biomedical Prevention (nBP) methods, such as topical or systemic pre-exposure prophylaxis (PrEP), are promising strategies to slow down the spread of AIDS. Methods: In this study, we investigated the microbicidal efficacy of the viral membrane-disrupting amphipathic SWLRDIWDWICEVLSDFK peptide called C5A...

African Americans are perceived to be least likely of all racial and ethnic groups to prepare for the end of life. However, verbal plans for the end of life are of particular importance to this population and may help understand why they are less likely to possess a formal end-of-life care planning document. The purpose of this study was to determine the number of formal and/or informal end-of-life care plans that existed among a convenience sample of African American older adults with dementia. For this descriptive study, data were collected from African American family caregivers (N = 65) of older adults with dementia...

Objectives: Acute myeloid leukemia (AML) is classified in part by recurrent cytogenetic abnormalities, often detected by both fluorescent in situ hybridization (FISH) and karyotype. The goal of this study was to assess the utility of FISH and karyotyping at diagnosis and follow-up. Methods: Adult AML samples at diagnosis or follow-up with karyotype and FISH were identified. Concordance was determined, and clinical characteristics and outcomes for discordant results were evaluated...

PURPOSE OF REVIEW: The aim of this study was to describe the newest development in cystic fibrosis (CF) care, CF transmembrane conductance regulator (CFTR) modulator therapies. RECENT FINDINGS: Phase II results showing CFTR modulator triple therapies are more effective than current CFTR modulators. SUMMARY: CFTR modulator therapy targets the protein defective in CF and boosts its function, but the drug must match mutation pathobiology. Ivacaftor, a CFTR potentiator, was the first modulator approved in 2012, with impressive improvement in lung function and other measures of disease in patients with gating and other residual function mutations (∼10% of CF patients)...

BACKGROUND: Catatonia-like presentations in people with autism have been increasingly recognised within research and diagnostic guidelines. The recently developed Attenuated Behaviour Questionnaire has identified that attenuated behaviour [autistic catatonia] is very prevalent in people with autism spectrum disorders (ASDs) and associated with repetitive behaviour. In the current study, we investigated attenuated behaviour within two genetic syndromes associated with ASD and examined ASD and repetitive behaviour as longitudinal predictors of attenuated behaviour...

INTRODUCTION: Although an increasing number of physicians are completing medical acupuncture training, only half of those physicians are able to successfully incorporate acupuncture into practice. We conducted a qualitative study to identify the factors and barriers that can enhance and impede physicians' delivery of and patients' engagement in medical acupuncture within the family medicine clinic. METHODS: We conducted interviews with 15 family physicians and 17 patients in a US family medicine clinic that has integrated medical acupuncture into its practice...

PREMISE OF THE STUDY: Gene space in plant plastid genomes is well characterized and annotated, yet we discovered an unrecognized open reading frame (ORF) in the fern lineage that is conserved across flagellate plants. METHODS: We initially detected a putative uncharacterized ORF by the existence of a highly conserved region between rps16 and matK in a series of matK alignments of leptosporangiate ferns. We mined available plastid genomes for this ORF, which we now refer to as ycf94, to infer evolutionary selection pressures and assist in functional prediction...

Shiga toxigenic Escherichia coli (STEC) are responsible for a worldwide foodborne disease, which is characterized by severe bloody diarrhea and hemolytic uremic syndrome (HUS). Subtilase cytotoxin (SubAB) is a novel AB5 toxin, which is produced by Locus for Enterocyte Effacement (LEE)-negative STEC. Cleavage of the BiP protein by SubAB induces endoplasmic reticulum (ER) stress, followed by induction of cytotoxicity in vitro or lethal severe hemorrhagic inflammation in mice. Here we found that steroids and diacylglycerol (DAG) analogues (e...

Lichens and mosses often share the same environmental conditions where they compete for substrate and other essential factors. Lichens use secondary metabolites as allelochemicals to repel surrounding plants and potential rivals. In mosses, endoreduplication leads to the occurrence of various ploidy levels in the same individual and has been suggested as an adaptation to abiotic stresses. Here, we show that also biotic factors such as usnic acid, an allelochemical produced by lichens, directly influenced the level of ploidy in mosses...

Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a chronic and unpredictable characterized by alternating periods of remission interspersed with relapses. In recent years accumulating support for an immunomodulating effect of vitamin D on both the innate and adaptive immune system has been presented. Through the vitamin D receptor, the active form of vitamin D, 1,25(OH)2D, induces antimicrobial peptide secretion, decrease dendritic cell activity, and promotes Th2 and regulatory T cell development and activity...

Mining activity releases toxic metals (TMs) into the soil ecosystem and creates serious problems for the environment and human beings due to their adverse eco-toxilogical impacts. Currently, several remediation techniques can be used to immobilize TMs within contaminated soil. The present study focuses on the application of different organic amendments biochar (B), farmyard manure (FYM) and peat moss (PTM) - at different application rates (1%, 2% and 5%) in mining-impacted agricultural soil to immobilize TMs (Ni, Cr, As, Zn, Cd and Pb) and minimize their bioaccumulation in pea (Pisum sativum) and chili (Capsicum annuum) and the associated human health risk...

500Ma ago the terrestrial habitat was a barren, unwelcoming place for species other than, for example, bacteria or fungi. Most probably, filamentous freshwater algae adapted to aerial conditions and eventually conquered land. Adaptation to a severely different habitat apparently included sturdy cell walls enabling an erect body plan as well as protection against abiotic stresses such as ultraviolet radiation, drought and varying temperature. To thrive on land, plants probably required more elaborate signaling pathways to react to diverse environmental conditions, and phytohormones to control developmental programs...

We investigated134 Cs and137 Cs activity concentrations in the common Japanese moss species Hypnum plumaeforme collected from 32 sites within ca. 100 km radius of the Fukushima Dai-ichi Nuclear Power Plant. A total of 32 samples of H. plumaeforme were collected during the field surveys from November 2013 to September 2014. The maximum radiocesium activity concentrations in H. plumaeforme were 60.9 ± 1.8 kBq kg-1 for134 Cs and 123 ± 2.3 kBq kg-1 for137 Cs. The mean value for the134 Cs/137 Cs was 1...

INTRODUCTION: Fatigue is one of the most common and disabling symptoms in end-stage kidney disease, particularly among in-centre haemodialysis patients. This two-arm parallel group feasibility randomised controlled trial will determine whether a fully powered efficacy trial is achievable by examining the feasibility of recruitment, acceptability and potential benefits of a cognitive-behavioural therapy (CBT)-based intervention for fatigue among in-centre haemodialysis patients. METHODS: We aim to recruit 40 adult patients undergoing in-centre haemodialysis at secondary care outpatient dialysis units, who meet clinical levels of fatigue...
