ABSTRACT Objective: To analyze the effect of air pollution on heart rate variability in overweight individuals. Methods: A total of 46 adult individuals, both sexes, aged between 18 and 49 years and with body mass index >25kg/m2 were analyzed. All volunteers were students from public schools of two cities in the state of São Paulo. The clinical, demographic and anthropometric data of each individual, as well as...
FUNDAMENTO: A literatura tem descrito dados contraditórios em relação ao início da diminuição da função barorreflexa em ratos espontaneamente hipertensos. OBJETIVO:Este estudo foi realizado para avaliar a função barorreflexa em ratos jovens de 13 semanas espontaneamente hipertensos. MÉTODOS:Foram estudados ratos machos Wistar Kyoto (WKY) (n=15) e ratos espontaneamente hipertensos (REH) de 13 semanas (n=15). Cân...
OBJECTIVE: To assess fluoxetine effects on mitochondrial structure of the right ventricle in rats exposed to cold stress. METHODS: The experimental study procedures were performed in 250-300g male EPM-Wistar rats. Rats (n=40) were divided into four groups: 1) Control group (CON); 2) Fluoxetine (FLU); 3) Induced hypothermia (IH) and; 4) Induced hypothermia treated with fluoxetine (IHF). Animals of FLU group were...

INTRODUCTION: Total body induced hypothermia and myocardial cooling are effective methods regarding myocardial protection during heart surgery and ischemia. It is described in previous studies that extreme low temperature exposure causes mitochondrial cristae and myofilament disarrangement in cardiomyocytes, however, no investigation has analyzed the effects of cold stress on nuclear size of cardiomyocytes.
