#1
Veronika Lerche, Andreas Voss
The diffusion model (Ratcliff, Psychol Rev 85(2):59-108, 1978) is a stochastic model that is applied to response time (RT) data from binary decision tasks. The model is often used to disentangle different cognitive processes. The validity of the diffusion model parameters has, however, rarely been examined. Only few experimental paradigms have been analyzed with those being restricted to fast response time paradigms. This is attributable to a recommendation stated repeatedly in the diffusion model literature to restrict applications to fast RT paradigms (more specifically, to tasks with mean RTs below 1...

Obesity and metabolic syndrome display disparate prevalence and regulation between males and females. Human, as well as rodent, females with regular menstrual/estrous cycles exhibit protection from weight gain and associated chronic diseases. These beneficial effects are predominantly attributed to the female hormone estrogen, specifically 17β-estradiol (E2). E2 exerts its actions via multiple receptors, nuclear and extranuclear estrogen receptor (ER) α and ERβ, and the G-protein-coupled estrogen receptor (GPER, previously termed GPR30)...

The neuroendocrine brain or hypothalamus has emerged as one of the most highly sexually dimorphic brain regions in mammals, and specifically in rodents. It is not surprising that hypothalamic nuclei play a pivotal role in controlling sex-dependent physiology. This brain region functions as a chief executive officer or master regulator of homeostatic physiological systems to integrate both external and internal signals. In this review, we describe sex differences in energy homeostasis that arise in one area of the hypothalamus, the ventrolateral subregion of the ventromedial hypothalamus (VMHvl) with a focus on how male and female neurons function in metabolic and behavioral aspects...

Sex difference plays a substantial role in the regulation of glucose metabolism in healthy glucose-tolerant humans. The factors which may contribute to the sex-related differences in glucose metabolism include differences in lifestyle (diet and exercise), sex hormones, and body composition. Several epidemiological and observational studies have noted that impaired glucose tolerance is more common in women than men. Some of these studies have attributed this to differences in body composition, while others have attributed impaired insulin sensitivity as a cause of impaired glucose tolerance in women...

In a climate change scenario, it is important to understand the factors that lead to changes in a soil carbon (C) sink. It is recognized that such process is highly dependent on climate, soil properties, topography, and vegetation. However, few studies demonstrate how these mechanisms operate in highly weathered Oxisols. Therefore, this study evaluated the driving factors for C recovery and accumulation and its relations with fertility attributes in the soil profile (0 to 1m depth) in no-till (NT) croplands of south Brazil...

The creation of in vitro functional hepatic tissue simulating micro-environmental niche of native liver is a keen area of research due to its demand in bioartificial liver (BAL) and cell-based tissue engineering. Here, we investigated the potential of novel blend (BA) silk scaffold fabricated by blending mulberry (Bombyx mori, BM) silk fibroin with cell adhesion motif (RGD) rich non-mulberry (Antheraea assamensis, AA) silk fibroin in generating a functional liver construct. Three-dimensional (3D) porous silk scaffolds (BM, AA and BA) were physico-chemically characterized and functionally evaluated using human hepatocarcinoma cells (HepG2) and primary neonatal rat hepatocytes...

Brenda Carey, Shane Erickson, Susan Block
PURPOSE: Speech restructuring treatment can effectively reduce stuttering but the resultant speech may sound unnatural. Martin et al. (1984) speech naturalness scale is widely used by clinicians and researchers, yet little is known about whether including normally fluent speech samples alters the judgement of the naturalness of speech samples of people who stutter, and whether attributes of listeners - specifically training and sex - influence ratings. METHODS: In this study 20 untrained listeners (male and female) and 19 speech language pathology students (female only) rated either the naturalness of 21 speech samples from adults who stutter obtained post-treatment, or the same 21 post-treatment samples randomly mixed with samples of 21 samples from normally fluent speakers matched for age and sex...

Folate status during pregnancy is important for fetal development and health. The placenta plays an important role in supplying the fetus with folate. Most women with epilepsy continue their medication during pregnancy. In the present study, we aimed to evaluate the effects of 16 antiepileptic drugs, clinically used for treatment of epilepsy, on folic acid uptake in two in vitro placental models, BeWo and JEG-3 cells. Short-term exposure to antiepileptic drugs had no effects on [3H]-folic acid uptake by BeWo cells...

Recently, designed platelet shaped micron particles that are composed of nano primary particles, called MicNo (=Micron+naNo) particles, have been developed to exploit the benefits of nano size, while removing the adverse effects of nanoparticles. It has been shown that MicNo-ZnO particles exhibit both micron and nanosized particle characteristics. Although physical and chemical properties of MicNo-ZnO particles have been studied, their biocompatibility has not yet been evaluated. Accordingly, the research objective of this study was to evaluate in vitro cytotoxicity, genotoxicity and phototoxicity behaviors of designed MicNo-ZnO particles over human epidermal keratinocyte (HaCaT) cells...

INTRODUCTION: Individuals with moderate or severe traumatic brain injury often experience impairments in pragmatic language functions. Pragmatic language has been studied primarily in connected language genres such as narratives. It may be, however, that individuals with traumatic brain injury also miss microscopic cues, such as social cues embedded in single word meanings or sentence structure. The current study examined one type of sentence-level pragmatic language cue: implicit causality bias...

Ring chromosome 15 [r(15)] is a rare condition with a mild-to-severe growth failure, mental disabilities, café-au-lait spots, specific facial features, fertility difficulties and other minor dysmorphic stigmata. Of almost 50 affected individuals reported in the literature, none were assessed for the precise breakpoint positioning, which creates uncertainty in defining a specific phenotype for the deleted segment. This study reports for the first time the vertical transmission of r(15) in three consecutive generations of a family, including a subfertile man, his mother and his newborn infant...

BACKGROUND: Percutaneous coronary intervention (PCI) is widely used; however, factors of high-cost care after PCI have not been thoroughly investigated. We sought to evaluate the in-hospital costs related to PCI and identify predictors of high costs. METHODS: We extracted 2,354 consecutive PCI cases (1,243 acute cases, 52.8%) from 3 Japanese cardiovascular centers from 2011 to 2015. In-hospital complications were predefined under consensus definitions (eg, acute kidney injury [AKI])...

BACKGROUND: Mediastinal infections are a potentially devastating complication of cardiac operations. This study analyzed the frequency, risk factors, and perioperative outcomes of mediastinal infections after cardiac operations. METHODS: In 2010, 5,158 patients enrolled in a prospective study evaluating infections after cardiac operations and their effect on readmissions and mortality for up to 65 days after the procedure. Clinical and demographic characteristics, operative variables, management practices, and outcomes were compared for patients with and without mediastinal infections, defined as deep sternal wound infection, myocarditis, pericarditis, or mediastinitis...

In tomato, Verticillium resistance is determined by the Ve gene locus encoding two leucine-rich repeat-receptor-like proteins (Ve1, Ve2). The resistance function usually is attributed to Ve1 alone, with two known alleles: Ve1, encoding a resistance protein, and ve1, with a premature stop codon encoding a truncated product. We have examined further Ve-gene expression in resistant and susceptible near-isolines of Verticillium-infected Craigella tomatoes, using both quantitative RT-PCR and an alternative RFLP assay...

BACKGROUND: While depression is a growing public health issue, the percentage of individuals with depression receiving treatment is low. Physical and social attributes of the neighborhood may influence the level of depressive symptoms and the prevalence of depression in older adults. METHODS: This review systematically examined the literature on neighborhood environmental correlates of depression in older adults. Findings were analyzed according to three depression outcomes: depressive symptoms, possible depression, and clinical depression...

Salts used for de-icing roads and sidewalks in northern climates can have a significant impact on water quality and vegetation. Sub-surface engineering systems, such as structural soil cells, can regulate water runoff and pollutants, and provide the necessary soil volume and irrigation to grow trees. However, the ability of such systems to manage de-icing salt contamination, and the impact of this contamination on the trees growing in them, have not been evaluated. We report on an field investigation of de-icing salt contamination in structural cells in two street-revitalization projects in Toronto, Canada, and the impact of this contamination on tree performance...

Jonathan M Lee
This study uses repeated cross-sections of individual level crash data to study the effectiveness of motorcycle helmet legislation. Results suggest that motorcycle helmet laws reduce average individual fatality risks by 20.5%. From a policy standpoint, large states such as Florida and Texas can reduce annual motorcycle fatalities by an average 100 deaths through reinstating universal helmet laws. Valuing these fatality reductions at the U.S. DOT suggested $9.4 million value of a statistical life yields aggregate annual state benefits of approximately $940 million...
