Software crowdsourcing (SW CS) is an evolving software development paradigm, in which crowds of people are asked to solve various problems through open call (with the encouragement prizes for top solutions). Because its dynamic nature, SW CS has been progressively accepted and adopted industry. However, issues pertinent understanding requirements among engineers yet be clarified explained. If n...

Molecules of diverse chemical structure are sweet to humans and several lines of evidence (genetic, physiological, behavioral) suggest that there may be distinct sweet perceptual qualities. To address how many perceptual categories these molecules elicit in hamsters (Mesocricetus auratus), we studied patterns of generalization of conditioned taste aversions for seven sweeteners: 100 mM sucrose,...

Objective: To estimate the pretest probability of Cushing’s syndrome (CS) diagnosis by a Bayesian approach using intuitive clinical judgment. Materials and methods: Physicians were requested, in seven endocrinology meetings, to answer three questions: “Based on your personal expertise, after obtaining clinical history and physical examination, without using laboratorial tests, what is your prob...

Acyl-coenzyme A:cholesterol acyltransferase (ACAT) is a membrane protein located in the endoplasmic reticulum (ER). It plays important roles in cellular cholesterol homeostasis. Human ACAT1 (hACAT1) contains nine cysteines (C). To quantify and map its disulfide linkage, we performed thiol-specific modifications by mPEG(5000)-maleimide (PEG-mal) and iodoacetamide (IA) under denatured condition, ...

PURPOSE The purpose of this study was to investigate the effect of bilberry on night visual acuity (VA) and night contrast sensitivity (CS). METHODS This study utilized a double-blind, placebo-controlled, crossover design. The subjects were young males with good vision; eight received placebo and seven received active capsules for three weeks. Active capsules contained 160 mg of bilberry extr...

Cells from patients with the UV-sensitive nucleotide excision repair disorder Cockayne's syndrome (CS) have a specific defect in preferential repair of lesions from the transcribed strand of active genes. This system permits quick resumption of transcription after UV exposure. Here we report the characterization of ERCC6, a gene involved in preferential repair in eukaryotes. ERCC6 corrects the ...

Psychophysiologic studies use air puff as an aversive stimulus to document abnormal fear conditioning in children of parents with anxiety disorders. This study used functional magnetic resonance imaging (fMRI) to examine changes in amygdala activity during air-puff conditioning among adults. Blood oxygen level-dependent (BOLD) signal was monitored in seven adults during 16 alternating presentat...

Both chronic ulcerative colitis and smoking are associated with colorectal cancer in humans. In the present study, we investigated the effects of cigarette smoke (CS) exposure on inflammation-associated tumorigenesis in the mouse colon. Male balb/c mice were allocated into six groups: control, CS (2%), CS (4%), colitis, colitis + CS (2%) and colitis + CS (4%). They were given water or 3% dextra...

BACKGROUND Recently, we reported that urinary 8-hydroxy-2'-deoxyguanosine (U-8-OHdG), an oxidative stress marker, reflected inflammatory activity in cardiac sarcoidosis (CS). Here, we investigated whether U-8-OHdG levels were associated with ventricular tachycardia (VT) in patients with CS. METHODS AND RESULTS This prospective cohort study enrolled 62 consecutive patients with CS, of whom 36 ...
