Background: Cigarette smoking has several known detrimental effect on cardiovascular system.  QT dispersion (QTd) is among the important predictors of cardiac death. Objective:  To assess the acute effect of smoking of a single standard cigarette on QT and QTc (corrected QT) dispersion, hence on the risk of ventricular arrhythmias in healthy smokers and non-smokers. Methods: 111 healthy men wit...

in their study, brenna and spandonaro analyzed the mobility into italian regions. in particular, it analyzes the situation of 5 regions, with very different backgrounds. with this paper, we try to better define the meaning of health mobility and to find its underlying causes. furthermore, we propose a strategy that could help in controlling mobility flows that currently are the source of health...

In this study, we focus on the impact of senior executives' industry backgrounds on the amount of capital raised in the stock market. The primary contribution of the study entails applying the upper echelon theory to the initial public offering (IPO) phenomenon. Specifically, we hypothesize that the industry backgrounds of corporate executives affect the amount of capital that the firm raised i...

The current weak lensing measurements of the large scale structure are mostly related to statistical study of background galaxy ellipticities. We consider a possibility to extend lensing studies with intrinsically unresolved sources and suggest that spatial fluctuations in the integrated diffuse emission from these sources can be used for a lensing reconstruction. Examples of upcoming possibili...

humans are equipped with some universal or language-specific abilities to recognize emotions. however, because of the different emotional contents in diverse languages and the relevant cultural differences, humans with different cultural backgrounds own different metapragmatical abilities to recognize and express emotions. a hypothesis concerning emotional effects about intonation and particle ...

Sandhoff disease is caused by mutations affecting the beta subunit of lysosomal beta-hexosaminidase (EC 3.2.1.52) and displays a wide spectrum of clinical phenotypes. We report a 57-year-old patient with a very mild phenotype, although residual hexosaminidase A activity in his cultured fibroblasts was less than 3% of normal activity, a level observed in juvenile onset patients. Northern and Wes...

Ticks secrete several anti-hemostatic factors in their saliva to suppress the host innate and acquired immune defenses against infestations. Using Ixodes scapularis ticks and age-matched mice purchased from two independent commercial vendors with two different immune backgrounds as a model, we show that ticks fed on immunodeficient animals demonstrate decreased fibrinogenolytic activity in comp...
