Premature ventricular complexes (PVCs), the first initiating beats of a variety of cardiac arrhythmias, have been associated with spontaneous calcium release (SCR) events at the cell level. However, the mechanisms underlying the degeneration of such PVCs into arrhythmias are not fully understood. The objective of this study was to investigate the conditions under which SCR-mediated PVCs can lea...

The Cockcroft-Gault (CG) equation has become perhaps the most popular practical approach for estimating renal function among health care professionals. Despite its widespread use, clinicians often overlook not only the limitations of the original serum creatinine (SCr) based equation, but also may not appreciate the validity of the many variations used to compensate for these limitations. For c...

Changes in physiological arousal frequently accompany cognitive performance. Many studies sought to identify the neural correlates of heightened arousal as indexed by skin conductance responses (SCR). However, the observed regional activations may be confounded by task events. We addressed this issue by recording SCR in 25 adults performing a stop signal task (SST) during functional magnetic re...

Scavenger receptor (ScR)-mediated uptake of modified lipoproteins may contribute to the transformation of smooth muscle cells into lipid-laden foam cells during atherogenesis. This study examined the in vivo expression of ScRs in aortas, with or without balloon injury, taken from hypercholesterolemic or normocholesterolemic rabbits. Numerous intimal cells in the rabbit aortic lesions expressed ...

Overlapping phasic skin conductance responses (SCRs) obtained using short interstimulus interval (ISI) paradigms such as those employed in cognitive research, confound measurement of each discrete phasic SCR as well as the tonic skin conductance level (SCL). We report a method of resolving this problem using a modelling technique that takes advantage of the stereotyped nature of the within-subj...

The objective of this study is to determine (a) if decision making ability is impaired in patients with anorexia nervosa (AN) and in people with good recovery from AN and (b) whether any impairment in decision making is associated with alterations in skin conductance responses (SCR). Patients with AN (n = 29), healthy controls comparable in age and IQ (HC, n = 29), and women long term recovered...

The purpose of this study is to develop a game system that uses biofeedback to provide an attractive entertaining game. In general, negative biofeedback is used for relaxing users; however, in our game system positive biofeedback is used for arousing them. We assumed that the latter biofeedback method could affect the users’ emotional states effectively; that is why we call it positive biofeedb...

As part of the new regulatory framework of Solvency II, introduced by the European Union, insurance companies are required to monitor their solvency by computing a key risk metric called the Solvency Capital Requirement (SCR). The official description of the SCR is not rigorous and has lead researchers to develop their own mathematical frameworks for calculation of the SCR. These frameworks are...

Sucrose is one of the most promising carbon sources for industrial fermentation. We expressed synthetic modules expressing genes of the PEP-PTS and non-PTS pathways in Escherichia coli K12 for comparison. We selected PEP-PTS pathway genes of Lactobacillus plantarum and Staphylococcus xylosus and non-PTS pathway genes of sucrose-utilizing (Scr(+)) E. coli EC3132. Switchable Scr(+) modules expres...

Heritability and genetic correlations for honey (HP) and propolis production (PP), hygienic behavior (HB), syrup-collection rate (SCR) and percentage of mites on adult bees (PMAB) of a population of Africanized honeybees were estimated. Data from 110 queen bees over three generations were evaluated. Single and multi-trait models were analyzed by Bayesian Inference using MTGSAM. The localization...
