Intranasal administration of the hypothalamic neuropeptide oxytocin (OT) has, in some studies, been associated with positive effects on social perception and cognition. Similarly, positive emotion inductions can improve a range of perceptual and performance-based behaviors. In this exploratory study, we examined how OT administration and positive emotion inductions interact in their associations with social and analytical performance. Participants (N=124) were randomly assigned to receive an intranasal spray of OT (40IU) or placebo and then viewed one of three videos designed to engender one of the following emotion states: social warmth, pride, or an affectively neutral state...

In Vietnam's concentrated HIV epidemic, female sex workers (FSWs) are at increased risk for acquiring and transmitting HIV, largely through their male clients. A high proportion of males in Vietnam report being clients of FSWs. Studying HIV-related risk factors and prevalence among male clients is important, particularly given the potential for male clients to be a 'bridge' of HIV transmission to the more general population or to sex workers. Time-location sampling was used to identify FSW in Hanoi and Ho Chi Minh City, Vietnam's largest cities, in 2013-2014...

PURPOSE: Adiponectin and chemerin have been reported their associations with insulin resistance and chronic inflammation. However, the relationship between adiponectin and chemerin themselves has not been fully elucidated. Therefore, we investigated the effects of changes in adiponectin and chemerin levels after a weight intervention. MATERIALS AND METHODS: We recruited 136 healthy overweight or obese subjects from 2006 to 2009 and provided all participants lifestyle modification therapy with diet consultations over 16 weeks...

The Magnet Recognition Program for healthcare organizations promotes excellence in nursing services and professional practices. However, organizational and community characteristics that contribute to the adoption of Magnet status remain unexplained. Investigating organizational and community factors will help determine systematic structural and contextual dimensions of Magnet hospitals previously shown to be more cost-effective in comparison with non-Magnet hospitals. Using the baseline 2005 database of all Magnet hospitals in the United States, the authors selected a matched sample to determine key organizational and community characteristics associated with Magnet adoption while controlling for regional and local factors...

Little is known about the link between gastric microbiota and the epidemiology of gastric cancer. In order to determine the epidemiologic and clinical relevance of gastric microbiota, we used 16S ribosomal RNA gene sequencing analysis to characterize the composition and structure of the gastric microbial community of 80 paired samples (non-malignant and matched tumor tissues) from gastric cardia adenocarcinoma (GCA) patients in Shanxi, China. We also used PICRUSt to predict microbial functional profiles. Compared to patients without family history of upper gastrointestinal (UGI) cancer in the non-malignant gastric tissue microbiota, patients with family history of UGI cancer had higher Helicobacter pylori (Hp) relative abundance (median: 0...

BACKGROUND: The intermediate group of patients with heart failure (HF) and mid-range left ventricular ejection fraction (HFmrEF) may constitute a specific phenotype, but a direct evidence is lacking. This study aimed to know whether this HF category is accompanied by a particular clinical phenotype and prognosis. METHODS AND RESULTS: This study includes 3446 ambulatory patients with chronic HF from two national registries. According to EF at enrollment, patients were classified as reduced (HFrEF, <40%), mid-range (HFmrEF, 40-49%) or preserved (HFpEF, ≥50%)...

Ion pairs and solubility related to ion-pairing in water influence many processes in nature and in synthesis including efficient drug delivery, contaminant transport in the environment, and self-assembly of materials in water. Ion pairs are difficult to observe spectroscopically because they generally do not persist unless extreme solution conditions are applied. Here we demonstrate two advanced techniques coupled with computational studies that quantify the persistence of ion pairs in simple solutions and offer explanations for observed solubility trends...

BACKGROUND: Death-associated protein kinase 1 (DAPK) is an important tumor suppressor kinase involved in the regulation of multiple cellular activities such as apoptosis and autophagy. DNA methylation of DAPK gene was found in various types of cancers and often correlated with the clinicopathological characteristics. However, the mRNA and protein expression of DAPK in the same sample was rarely measured. Thus, it was unclear if the correlation between DAPK gene methylation and clinicopathological parameters was due to the loss of DAPK expression...

The present paper studies semidiscrete surfaces in three-dimensional Euclidean space within the framework of integrable systems. In particular, we investigate semidiscrete surfaces with constant mean curvature along with their associated families. The notion of mean curvature introduced in this paper is motivated by a recently developed curvature theory for quadrilateral meshes equipped with unit normal vectors at the vertices, and extends previous work on semidiscrete surfaces. In the situation of vanishing mean curvature, the associated families are defined via a Weierstrass representation...

Meiotic crossover frequencies show wide variation among organisms. But most organisms maintain at least one crossover per homolog pair (obligate crossover). In Saccharomyces cerevisiae, previous studies have shown crossover frequencies are reduced in the mismatch repair related mutant mlh3Δ and enhanced in a meiotic checkpoint mutant pch2Δ by up to two-fold at specific chromosomal loci, but both mutants maintain high spore viability. We analyzed meiotic recombination events genome-wide in mlh3Δ, pch2Δ and mlh3Δ pch2Δ mutants to test the effect of variation in crossover frequency on obligate crossovers...
