There is growing appreciation for the substantial individual differences in the acquisition and inhibition of aversive associations, and the insights this might give into identifying individuals particularly vulnerable to stress and psychopathology. We examined whether animals that differed in rate of extinction (i.e., Fast versus Slow) were different in their response to an acute stress in adulthood or following a chronic stress that occurred either early or later in life. We found that Slow Extinguishers had significantly poorer extinction retention than Fast Extinguishers, but an acute stressor did not differentially affect anxiety-like behavior in the two groups...

Profiling of protease specificity is crucial for characterization of these important enzymes that play numerous roles in health and disease. In the past, several proteomic methods have been developed that enable profiling of protease specificities. Although able to identify thousands of protease cleavage events, these degradomics approaches are often time consuming and methodologically challenging, which limits their application to specialized proteomic groups or the laboratories that initially introduced them...

By creating holes in 2D nanosheets, tortuosity and porosity can be greatly tunable, which enables a fast manufacturing process (i.e., fast removal of gas and solvent) toward various nanostructures. We demonstrated outstanding compressibility of holey graphene nanosheets, which is impossible for pristine graphene. Holey graphene powder can be easily compressed into dense and strong monoliths with different shapes at room temperature without using any solvents or binders. The remarkable compressibility of holey graphene, which is in sharp contrast with pristine graphene, not only enables the fabrication of robust, dense graphene products that exhibit high density (1...

BACKGROUND: Pneumonia is the main cause of child mortality world-wide and most of these deaths occur in sub-Saharan Africa (SSA). Treatment with effective antibiotics is crucial to prevent these deaths; nevertheless only 2 out of 5 children with symptoms of pneumonia are taken to an appropriate care provider in SSA. While various factors associated with care seeking have been identified, the relationship between caregivers' knowledge of pneumonia symptoms and actual care seeking for their child with symptoms of pneumonia is not well researched...

Headache attributable to disorders of homeostasis represents a diverse diagnostic category in which external (i.e., high-altitude) or internal (i.e., fasting) demands exceed homeostatic capacity, resulting in symptomatic headaches. Metabolic headaches, especially fasting headache, have been observed to be common in the general population. In many cases, a history of migraine is a risk factor, consistent with the hypothesis of an adaptive, evolutionary role of headache to warn against environmental and physiological threats...

BACKGROUND: In eye movement desensitization and reprocessing (EMDR), patients make eye movements (EM) while recalling traumatic memories. Making EM taxes working memory (WM), which leaves less resources available for imagery of the memory. This reduces memory vividness and emotionality during future recalls. WM theory predicts that individuals with small working memory capacities (WMCs) benefit more from low levels of taxing (i.e., slow EM) whereas individuals with large WMC benefit more from high levels of taxing (i...

OBJECTIVES: This study examines the influence of adolescents' exposure to unhealthy food outlets on junk food purchasing during trips between home and school, with particular attention to how exposure and purchasing differ according to child's biological sex, mode of transportation, and direction to or from school. METHODS: Between 2010 and 2013, students (n = 654) aged 9-13 years from 25 schools in London and Middlesex County, ON, completed a socio-demographic survey and an activity diary (to identify food purchases), and were observed via a global positioning system for 2 weeks (to track routes for trips to/from school)...

Research progressing during the last decade focuses more on non-contact based systems to monitor Heart Rate (HR) which are simple, low-cost and comfortable to use. Most of the non-contact based systems are using RGB videos which is suitable for lab environment. However, it needs to progress considerably before they can be applied in real life applications. As luminance (light) has significance contribution on RGB videos HR monitoring using RGB videos are not efficient enough in real life applications in outdoor environment...

Recent studies have demonstrated that repeated short-term nutrient withdrawal (i.e. fasting) has pleiotropic actions to promote organismal health and longevity. Despite this, the molecular physiological mechanisms by which fasting is protective against metabolic disease are largely unknown. Here, we show that, metabolic control, particularly systemic and liver lipid metabolism, is aberrantly regulated in the fasted state in mouse models of metabolic dysfunction. Liver transcript assays between lean/healthy and obese/diabetic mice in fasted and fed states uncovered "growth arrest and DNA damage-inducible" GADD45β as a dysregulated gene transcript during fasting in several models of metabolic dysfunction including ageing, obesity/pre-diabetes and type 2 diabetes, in both mice and humans...

Excess nutrients are potential factors that drive phase shifts from seagrasses to macroalgae. We carried out a manipulative field experiment to study the effects of macroalgae Ulva pertusa loading and nutrient addition to the water column on the nitrogen (N) and carbon (C) contents (i.e., fast indicators) as well as on the morphology and structure (i.e., slow indicators) of Zostera marina. Our results showed rapid impact of increased macroalgae and nutrient load on Z. marina C/N ratios. Also, macroalgae addition resulted in a trend of decreasing belowground biomass of seagrasses, and nutrient load significantly decreased above to belowground biomass ratio...

PURPOSE: The prevalence of phenotypes of Arylamine N-acetyltransferase-2(NAT2) gene (i.e. fast, intermediate and slow acetylators) among ethnic groups, as well as the association studies regarding NAT2 polymorphisms and risk of breast cancer produced inconsistent results. This meta-analysis aimed to clarify whether the selected NAT2 phenotypes have an effect on the susceptibility to breast cancer. METHODS: After aggregating the frequencies of fast, intermediate and slow phenotypes of NAT2 in breast cancer subjects, the odds ratio and relevant 95% confidence intervals were examined using combined data from all published 36 articles...

Genetic selection for enhanced growth rate in meat-type chickens (Gallus domesticus) is usually accompanied by excessive adiposity, which has negative impacts on both feed efficiency and carcass quality. Enhanced visceral fatness and several unique features of avian metabolism (i.e., fasting hyperglycemia and insulin insensitivity) mimic overt symptoms of obesity and related metabolic disorders in humans. Elucidation of the genetic and endocrine factors that contribute to excessive visceral fatness in chickens could also advance our understanding of human metabolic diseases...

Hybrid revasculization of myocardium combined the advantages of mammary-coronary bypass surgery and coronary arteries stenting. It presented itself as a perspective direction in treatment of ischemic coronary disease. The article provides the results of comparison of usage of hybrid revasculization of myocardium and aortocoronary bypass in 71 patients with multivessel coronary artery disease. The data obtained indicated, that hybrid approach allowed complete revasculization of the myocardium (as in case of aortocoronary bypass), fast recovery of the patient, shortening a hospital stay due to decrease of intra- and postoperative complications...
