The sulfation at the 3-OH position of glucosamine is an important modification in forming structural domains for heparan sulfate to enable its biological functions. Seven 3-O-sulfotransferase isoforms in the human genome are involved in the biosynthesis of 3-O-sulfated heparan sulfate. As a rare modification present in heparan sulfate, the availability of 3-O-sulfated oligosaccharides is very limited. Here, we report the use of a chemoenzymatic synthetic approach to synthesize six 3-O-sulfated oligosaccharides, including three hexasaccharides and three octasaccharides...

People who are "triply diagnosed" with HIV, mental health issues, and substance-related disorders face tremendous barriers connecting to and remaining in HIV care. Authors of this article implemented Project Bridge Oakland (PBO), an intervention based on harm reduction and trauma-informed care, to help maintain continuity of care for triply diagnosed adults through cycles of criminal justice involvement. From August 2011 to December 2014, a clinical social worker and an HIV physician provided intensive case management for 19 clients living in Oakland, California...

Social workers frequently encounter clients with a history of trauma. Trauma-informed care is a way of providing services by which social workers recognize the prevalence of early adversity in the lives of clients, view presenting problems as symptoms of maladaptive coping, and understand how early trauma shapes a client's fundamental beliefs about the world and affects his or her psychosocial functioning across the life span. Trauma-informed social work incorporates core principles of safety, trust, collaboration, choice, and empowerment and delivers services in a manner that avoids inadvertently repeating unhealthy interpersonal dynamics in the helping relationship...

BACKGROUND: The mortality of dialysis patients is 10- to 100-fold higher than in the general population. Baseline serum PTH levels, and more recently, changes in serum PTH levels (ΔPTH) over time, have been associated to mortality in dialysis patients. METHODS: We explored the relationship between ΔPTH over 1 year with mortality over the next year in a prospective cohort of 115 prevalent hemodialysis patients from a single center that had median baseline iPTH levels within guideline recommendations...

Background: High levels of serum gamma-glutamyltransferase (GGT) are associated with increased risk of prediabetes and type 2 diabetes in observational studies. It is unclear whether this relationship is causal, arises from residual confounding or is a consequence of reverse causation. Methods: We used data from a prospective population-based cohort study, compromising 8611 individuals without diabetes at baseline. Cox proportional hazard models were used to study the association between serum GGT levels and incident prediabetes and diabetes...

OBJECTIVE: The use of topical local anesthetics in the form of creams, gel or spray is the oldest method of retarding ejaculation. However, several studies have suggested that phosphodiesterase type 5 inhibitors (5-PDEiS) show a potential therapeutic use in the treatment of premature ejaculation (PE). The aim of this study was to compare the efficacy and tolerability of tadalafil-only, tadalafil plus local anesthetic spray (lidocaine), and topical lidocaine spray-only before intercourse on the intravaginal ejaculatory latency time (IELT) of patients with lifelong PE...

Cadmium (Cd) is a carcinogen with several well-described toxicological effects in humans, but its molecular mechanisms are still not fully understood. Overexpression of heat shock protein 27 (HSP27/HSPB1)-a multifunctional protein chaperone-has been shown to protect cells from oxidative damage and apoptosis triggered by Cd exposure. The aims of this work were to investigate the potential use of extracellular recombinant HSP27 to prevent/counteract Cd-induced cellular toxicity and to evaluate if peroxynitrite was involved in the development of Cd-induced toxicity...

Neuromonitoring can be used to observe intracranial pathological conditions in neurointensive care, but use of intracranial pressure (ICP) monitoring is low in Japan. In this study, we retrospectively investigated the effects of ICP monitoring in treatment of severe traumatic brain injury (TBI) using data from the Japan Neurotrauma Data Bank (JNTDB). The study was conducted in 1,091 subjects enrolled in the JNTDB (Project 2009) from July 2009 to June 2011. The subjects were divided into those treated with and without ICP monitoring in intensive care for severe TBI...

The new porcine epidemic diarrhea (PED) has caused devastating economic losses to the swine industry worldwide. Despite extensive research on the relationship between autophagy and virus infection, the concrete role of autophagy in porcine epidemic diarrhea virus (PEDV) infection has not been reported. In this study, autophagy was demonstrated to be triggered by the effective replication of PEDV through transmission electron microscopy, confocal microscopy, and Western blot analysis. Moreover, autophagy was confirmed to benefit PEDV replication by using autophagy regulators and RNA interference...

Macro- and microvascular complications are currently the principal causes of morbidity and mortality in patients with diabetes mellitus. Aim of this study was to determine if type 2 diabetic patients with nephropathy and coronary artery disease showed altered platelet-derived nitric oxide (NO) production, compared with diabetic subjects without complications, and if this alteration is also present in their diabetic offspring. In this case-control observational study, platelet NO and peroxynitrite content was determined on plasma from 60 male adult type 2 diabetic patients and 60 male offspring type 2 diabetic patients...

Antipsychotic drugs, originally developed to treat schizophrenia, are used to treat psychosis, agitation and aggression in Alzheimer's disease. In the absence of dopamine D2/3 receptor occupancy data to inform antipsychotic prescribing for psychosis in Alzheimer's disease, the mechanisms underpinning antipsychotic efficacy and side effects are poorly understood. This study used a population approach to investigate the relationship between amisulpride blood concentration and central D2/3 occupancy in older people with Alzheimer's disease by combining: (i) pharmacokinetic data (280 venous samples) from a phase I single (50 mg) dose study in healthy older people (n = 20, 65-79 years); (ii) pharmacokinetic, 18F-fallypride D2/3 receptor imaging and clinical outcome data on patients with Alzheimer's disease who were prescribed amisulpride (25-75 mg daily) to treat psychosis as part of an open study (n = 28; 69-92 years; 41 blood samples, five pretreatment scans, 19 post-treatment scans); and (iii) 18F-fallypride imaging of an antipsychotic free Alzheimer's disease control group (n = 10, 78-92 years), to provide additional pretreatment data...

BACKGROUND: The main role of the cell cycle is to enable error-free DNA replication, chromosome segregation and cytokinesis. One of the best characterised checkpoint pathways is the spindle assembly checkpoint, which prevents anaphase onset until the appropriate attachment and tension across kinetochores is achieved. MPS1 kinase activity is essential for the activation of the spindle assembly checkpoint and has been shown to be deregulated in human tumours with chromosomal instability and aneuploidy...

Motivation: Over the past decade, there has been a remarkable improvement in our understanding of the role of genetic variation in complex human diseases, especially via genome-wide association studies. However, the underlying molecular mechanisms are still poorly characterized, impending the development of therapeutic interventions. Identifying genetic variants that influence the expression level of a gene, i.e. expression quantitative trait loci (eQTLs), can help us understand how genetic variants influence traits at the molecular level...

OBJECTIVES: Breakdown of marriage and cohabitation is common in Western countries and is costly for individuals and society. Most research on reasons for breakdown has focused on marriages ending in divorce and/or have used data unrepresentative of the population. We present prevalence estimates of, and differences in, reported reasons for recent breakdown of marriages and cohabitations in Britain. METHODS: Descriptive analyses of data from Britain's third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), a probability sample survey (15,162 people aged 16-74 years) undertaken 2010-2012, using computer-assisted personal interviewing...

BACKGROUND: Environmental factors play a major role on atopic dermatitis (AD) which shows a constant rise in prevalence in western countries over the last decades. The Hygiene Hypothesis suggesting an inverse relationship between incidence of infections and the increase in atopic diseases in these countries, is one of the working hypothesis proposed to explain this trend. OBJECTIVE: This study tested the efficacy and safety of oral administration of the bacterial lysate OM-85 (Broncho-Vaxom®, Broncho-Munal®, Ommunal®, Paxoral®, Vaxoral®), in the treatment of established AD in children...

STUDY QUESTION: Can pharma drug discovery approaches be utilized to transform investigation into novel therapeutics for male infertility? SUMMARY ANSWER: High-throughput screening (HTS) is a viable approach to much-needed drug discovery for male factor infertility. WHAT IS KNOWN ALREADY: There is both huge demand and a genuine clinical need for new treatment options for infertile men. However, the time, effort and resources required for drug discovery are currently exorbitant, due to the unique challenges of the cellular, physical and functional properties of human spermatozoa and a lack of appropriate assay platform...
