The Exercise Preconditioning Effect on Cardiac Tissue Injury following Induction of Myocardial Infarction in Male Rats.

Materials And Methods: Twenty-four male rats were divided into 4 groups including MI, Sham, HIIT, and HIIT+MI ( = 6). HIIT and HIIT+MI which underwent high-intensity interval training (HIIT) for 4 weeks (5 days a week). The training protocol included 10 intervals of 1-minute running, with 2 minutes rest between each interval.

Changes in mitochondrial biogenesis and fatty liver indicators in rat following continuous and high intensity interval training.

Background: Oxidative stress and mitochondrial dysfunction can be tracked down in most liver diseases like non-alcoholic fatty liver disease (NAFLD). The most recommended preventative method is lifestyle modification, especially exercise. The aim of this study was the investigation of changes in the indexes of mitochondrial biogenesis and fatty liver indicators in rat following continuous and high intensity interval training.

Acute and chronic exposure of chick embryo to ethanol alters brain neurosteroid levels.

Neurosteroids are modulators of neuronal function that may play important role in brain maturation. The aim of the present investigation was to study the effect of prenatal exposure to acute and chronic ethanol on brain progesterone, estradiol, and testosterone concentration on 10th and 15th days following egg incubation. Eggs were exposed to ethanol at 10 % in chronic treatment and 70 % in acute treatment.
