BACKGROUND: An anti-programmed cell death protein 1 monoclonal antibody, nivolumab, is one of the most effective drugs for advanced melanoma. Tumor cell-derived or immune cell-derived markers and clinical predictors such as serum lactate dehydrogenase (LDH) and cutaneous adverse events, have already been described as prognostic factors for advanced melanoma treated with nivolumab. We sought to identify further clinical predictors that can be determined in routine clinical practice. METHODS: We retrospectively analyzed clinical findings of 98 consecutive patients with unresectable stage III or IV melanoma treated with nivolumab, at the National Cancer Center Hospital or at Keio University Hospital, in Tokyo, Japan, between July 2014 and July 2016...

The primary physiological function of Krüppel-like zinc-finger transcription factor (KLF5) is the regulation of cardiovascular remodeling. Vascular remodeling is closely related to the amelioration of various ischemic diseases. However, the underlying correlation of KLF5 and ischemia is not clear. In this study, we aim to investigate the role of KLF5 in myocardial ischemia reperfusion (IR) injury and the potential mechanisms involved. Cultured H9C2 cells were subjected to oxygen-glucose deprivation/reperfusion (OGD/Rep) to mimic myocardial IR injury in vivo...

Discovery of somatic mutations in the calreticulin gene (CALR) has identified a subgroup of Philadelphia-negative chronic myeloproliferative neoplasms (MPN) with separate haematological characteristics and prognosis. CALR mutations serve as novel markers both of diagnostic value and as targets for monitoring molecular responses during therapy. Interferon-α (IFN) selectively targets the malignant clone in a subset of MPN patients and can induce both haematological and molecular remissions in CALR mutated essential thrombocythemia (ET) patients...

During exercise, cutaneous vasodilation and sweating responses occur, whereas these responses rapidly decrease during postexercise recovery. We hypothesized that the activation of endothelin A (ETA) receptors, but not endothelin B (ETB) receptors, attenuate cutaneous vasodilation during high-intensity exercise and contribute to the subsequent postexercise suppression of cutaneous vasodilation. We also hypothesized that both receptors increase sweating during and following high-intensity exercise. Eleven males (24 ± 4 years) performed an intermittent cycling protocol consisting of two 30-min bouts of moderate- (40% VO2peak) and high- (75% VO2peak) intensity exercise in the heat (35°C), each separated by a 20- and 40-min recovery period, respectively...

We tested whether exposure of beta cells at reduced glucose leads to mitochondrial adaptions and whether such adaptions modulate effects of hypoxia. Rat islets, human islets and INS-1 832/13 cells were pre-cultured short term at half standard glucose concentrations (5.5 mM for rat islets and cells, 2.75 mM for human islets) without overtly negative effects on subsequently measured function (insulin secretion and cellular insulin contents) or on viability. Culture at half standard glucose upregulated complex I and tended to upregulate complex II in islets and INS-1 cells alike...

Betaine serves as an animal and human nutrient which has been heavily investigated in glucose and lipid metabolic regulation, yet the underlying mechanisms are still elusive. In this study, feeding sows with betaine-supplemented diets during pregnancy and lactation increased cholesterol content and low-density lipoprotein receptor (LDLR) and scavenger receptor class B type I (SR-BI) gene expression, but decreasing bile acids content and cholesterol-7a-hydroxylase (CYP7a1) expression in the liver of weaning piglets...

OBJECTIVE: This systematic review aimed to evaluate the scientific evidence on the efficacy of desensitizing mouthwashes for the treatment of dentin hypersensitivity (DH) and root sensitivity (RS). MATERIAL AND METHODS: A thorough search in MEDLINE, PubMed and Cochrane Plus Library was conducted up to February 2015. Randomized clinical trials, parallel, double-blinded and placebo-controlled, with a follow-up of at least 6 weeks, reporting changes on response to tactile stimuli, thermal/evaporative stimuli or patients' subjective assessment of the pain experienced during their daily life after the home use of desensitizing mouthwashes were considered for inclusion...

In this review, we address significant characteristics of parturition in the pig and their connection to post-partum reproductive health and fertility. We discuss the normal physiology and behaviour around parturition and the effect of the second phase (expulsion of foetuses) on the third phase of parturition (expulsion of foetal membranes). In addition, we intend to cover retained placenta, and the connection to post-partum uterine health and fertility in the contemporary prolific sow. We also explore factors that support successful parturition or can cause potential problems...

The chromatin contains the genetic and the epigenetic information of a eukaryotic organism. Posttranslational modifications of histones, such as acetylation and methylation, regulate their structure and control gene expression. Histone acetyltransferases (HATs) acetylate lysine residues in histones while histone deacetylases (HDACs) remove this modification. HDAC inhibitors (HDACi) can alter gene expression patterns and induce cytotoxicity in cancer cells. Here we provide an overview of methods to determine the cytotoxic effects of HDACi treatment...

INTRODUCTION: Increasing smartphones access has allowed for increasing development and use of smart phone applications (apps). Mobile health interventions have previously relied on voice or text-based short message services (SMS), however, the increasing availability and ease of use of apps has allowed for significant growth of smartphone apps that can be used for health behaviour change. This review considers the current body of knowledge relating to the evaluation of apps for health behaviour change...

: We investigated 10 mother-newborn pairs and found a 90% rate of dengue virus (DENV) transmission during the perinatal period. Here, we describe DENV kinetics in the sera of newborns before the onset of disease. Of the breast-milk samples analyzed, 75% tested positive for DENV. BACKGROUND: Dengue is the most common mosquito-borne viral disease in humans. With this study, we aimed to investigate the risk of vertical (DENV) transmission during the peripartum period and to describe its viral kinetics in serum and breast milk...

BACKGROUND: Enteric fermentation by farmed ruminant animals is a major source of methane and constitutes the second largest anthropogenic contributor to global warming. Reducing methane emissions from ruminants is needed to ensure sustainable animal production in the future. Methane yield varies naturally in sheep and is a heritable trait that can be used to select animals that yield less methane per unit of feed eaten. We previously demonstrated elevated expression of hydrogenotrophic methanogenesis pathway genes of methanogenic archaea in the rumens of high methane yield (HMY) sheep compared to their low methane yield (LMY) counterparts...

During physical activity in McArdle patients, little or no lactate is released in the skeletal muscle. However, excessive ammonia production has frequently been reported in these patients. Production of ammonia is catalysed by AMP deaminase (AMPD) and adenylate kinase (AK). The activities of AMPD and AK along with housekeeping enzyme phosphoglucoisomerase (PGI) were measured in 11 genetically confirmed McArdle patients and compared with 27 healthy controls. The AMPD and AK activities were not significantly different in patients and controls...

α-Defensin 5 is important to both maintenance of a gut microbiota and host immunity. While previous reports have shown that gut bacteria are able to upregulate α-defensin 5 through Toll-like receptor signaling, we demonstrate here that α-defensin 5 expression can also be regulated by microbial metabolites. Among these, lactate appeared to significantly suppress α-defensin 5 gene transcription. Actually, fractions of <3 kD compounds obtained from the ceca of SPF mice were suppressed α-defensin 5 gene transcription at specific concentrations...

This work presents a fluid dynamic study of milk flow in lactating human breast. The motivation for this study is in part to improve the fundamental understanding of transport processes in an important but insufficiently studied human organ, and in part to produce a new methodology for the understanding of the pathologies of lactation, which can have a huge impact on the health and well-being of a significant proportion of the population. This collaborative effort among lactation specialists and fluid dynamic engineers starts with a careful, statistically representative measurement of infant suckling patterns...

The pneumococcus is one of the most prodigious producers of hydrogen peroxide amongst bacterial pathogens. Hydrogen peroxide production by the pneumococcus has been implicated in antibiotic synergism, competition between other bacterial colonizers of the nasopharynx, and damage to epithelial cells. However, the role during invasive disease has been less clear with mutants defective in hydrogen peroxide production demonstrating both attenuation and heightened invasive disease capacity depending upon strain and serotype background...
