We investigated the functional role and clinical significance of Stearoyl CoA desaturase-1 (SCD1) mediated endoplasmic reticulum (ER) stress in regulation of liver tumor-initiating cells (T-ICs) and sorafenib resistance, aiming to develop a novel therapeutic strategy against hepatocellular carcinomas (HCCs) METHODS We evaluated the clinic-pathological relevance of SCD1 and its correlation with sorafenib resistance in large cohorts of HCC clinical samples by qPCR and immunohistochemical analyses. Lentiviral-based overexpression and knockdown approaches were performed to characterize functional roles of SCD1 in regulation of liver T-ICs and sorafenib resistance...

BACKGROUND: The increasing rate of compulsory admission to psychiatric inpatient beds in England is worrying. Studying variation between places and services could be key to identifying targets for interventions to reverse this trend. We modelled spatial variation in compulsory admissions in England using national patient-level data and quantified the extent to which patient, local-area, and service-setting characteristics accounted for this variation. METHODS: This study is a cross-sectional, multilevel analysis of the 2010-11 Mental Health Minimum Data Set (MHMDS)...

BACKGROUND: Direct-acting antiviral therapy (DAAs) for hepatitis C infection (HCV) have a much smaller burden of treatment than interferon-based regimes, require less monitoring and are very effective. New pathways are required to increase access to treatment amongst people prescribed opioid substitution therapy (OST). METHODS: An exploratory cluster randomised controlled trial with mixed methods evaluation was undertaken to compare the uptake of dried blood spot testing (DBST) and treatment of people with genotype 1 HCV infection in a conventional service pathway versus a pharmacist-led pathway in a population receiving OST...

Maintenance of hair follicle (HF) stem cell quiescence and self-renewal are key functions of a specific cellular niche represented by the HF bulge and adjacent cell populations. The unique context of this niche is crucial for normal HF functioning, but mechanisms implicated in its maintenance are still not quite clear. The Letter to the Editor by Sada et al. introduces a novel Slc1a3-CreER genetic mouse model which, in contrast to previously reported marking tools, selectively and highly efficiently demarcates the telogen bulge inner layer, one of the critical structural components of the bulge stem cell niche...

Management of idiopathic nephrotic syndrome in children is based on a series of clinical trials. The trial by Sinha and colleagues in this issue is 1 of many needed to improve the evidence base for induction and maintenance therapies in this population. While key questions remain about identifying the appropriate therapy for each patient, clinical trials provide an opportunity to extend evidence-based practice that minimizes toxicity and optimizes patient health.

BACKGROUND: Client-centred task-oriented training is important in neurological rehabilitation but is time consuming and costly in clinical practice. The use of technology, especially motion capture systems (MCS) which are low cost and easy to apply in clinical practice, may be used to support this kind of training, but knowledge and evidence of their use for training is scarce. The present review aims to investigate 1) which motion capture systems are used as training devices in neurological rehabilitation, 2) how they are applied, 3) in which target population, 4) what the content of the training and 5) efficacy of training with MCS is...

BACKGROUND: In 2010 a public sector cadre of community health workers called Community Health Assistants (CHAs) was created in Zambia through the National Community Health Worker Strategy to expand access to health services. This cadre continues to be scaled up to meet the growing demands of Zambia's rural population. We summarize factors that have facilitated the scale-up of the CHA program into a nationwide CHW cadre and the challenges of introducing and institutionalizing the cadre within the Zambian health system...

Anchovies represent the largest world's marine fish catches and the current threats on their populations impose a sustainable exploitment based on sound scientific information. In the European anchovy (Engraulis encrasicolus), the existence of several populations has been proposed but a global view is missing. Using a multidisciplinary approach, here we assessed the divergence among different ecotypes and its possible causes. SNPs have revealed two functionally distinct ecotypes overlapping in the Central Mediterranean, with one ecotype confined near the river estuaries...

Diana White, Stéphane Honoré, Florence Hubert
Microtubules (MTs) play a key role in normal cell development and are a primary target for many cancer chemotherapy MT targeting agents (MTAs). As such, understanding MT dynamics in the presence of such agents, as well as other proteins that alter MT dynamics, is extremely important. In general, MTs grow relatively slowly and shorten very fast (almost instantaneously), an event referred to as a catastrophe. These dynamics, referred to as dynamic instability, have been studied in both experimental and theoretical settings...

Citreoviridin (CIT) is a mycotoxin produced by Penicillum citreonigrum, Aspergillus terreus and Eupenicillium ochrosalmoneum. CIT occurs naturally in moldy rice and corn. CIT is associated with the development of atherosclerosis in the general population. Alteration in hepatic lipid metabolism is a pathogenic factor in atherosclerosis. However the effect and the underlying mechanism of CIT on hepatic lipid metabolism are largely unknown. In this study, we reported that CIT induced triglyceride accumulation in mice liver and human liver HepG2 cells as shown in oil red O staining...

Foojan Mehrdana, Kurt Buchmann
Parasites from the family Anisakidae are widely distributed in marine fish populations worldwide and mainly nematodes of the three genera Anisakis, Pseudoterranova and Contracaecum have attracted attention due to their pathogenicity in humans. Their life cycles include invertebrates and fish as intermediate or transport hosts and mammals or birds as final hosts. Human consumption of raw or underprocessed seafood containing third stage larvae of anisakid parasites may elicit a gastrointestinal disease (anisakidosis) and allergic responses...

BACKGROUND: Cannabis use is common in North America, especially among young people, and is associated with a risk of various acute and chronic adverse health outcomes. Cannabis control regimes are evolving, for example toward a national legalization policy in Canada, with the aim to improve public health, and thus require evidence-based interventions. As cannabis-related health outcomes may be influenced by behaviors that are modifiable by the user, evidence-based Lower-Risk Cannabis Use Guidelines (LRCUG)-akin to similar guidelines in other health fields-offer a valuable, targeted prevention tool to improve public health outcomes...

The genetic features of isolated populations can boost power in complex-trait association studies, and an in-depth understanding of how their genetic variation has been shaped by their demographic history can help leverage these advantageous characteristics. Here, we perform a comprehensive investigation using 3,059 newly generated low-depth whole-genome sequences from eight European isolates and two matched general populations, together with published data from the 1000 Genomes Project and UK10K. Sequencing data give deeper and richer insights into population demography and genetic characteristics than genotype-chip data, distinguishing related populations more effectively and allowing their functional variants to be studied more fully...

BACKGROUND: Caregivers of cancer patients experience significant burden and distress including depression and anxiety. We previously demonstrated the efficacy of an eight session, in-person, one-on-one stress management intervention to reduce distress in caregivers of patients receiving allogeneic hematopoietic stem cell transplants (allo-HSCT). OBJECTIVE: The objective of this study was to adapt and enhance the in-person caregiver stress management intervention to a mobilized website (eg, tablet, smartphone, or computer-based) for self-delivery in order to enhance dissemination to caregiver populations most in need...

The basic reproduction number R0 is a key parameter in plant disease epidemiology, which largely determines whether or not an epidemic will occur in a plant population. The next generation matrix approach to deriving and calculating the basic reproduction number of a plant virus epidemic is described. The approach is illustrated through a series of examples of increasing complexity, ranging from the simplest case of one vector transmitting one virus to a single host, to the case of multiple vectors, to combined horizontal (vector) and vertical (seed) transmission, and where vector control using insecticides is practised...
