The aim of this review was to examine the mechanisms by which physical activity and inactivity modify muscle fatigue. It is well known that acute or chronic increases in physical activity result in structural, metabolic, hormonal, neural, and molecular adaptations that increase the level of force or power that can be sustained by a muscle. These adaptations depend on the type, intensity, and vo...
Aim The stromal invasion has been regarded as the most valuable clue to distinguish high-grade dysplastic nodules (HGDNs) and well-differentiated small hepatocellular carcinomas (WD-SHCCs). The purposes of this study are to explore the stromal morphological changes for the differential diagnosis of these two equivocal lesions. Results Based on the systemic studies of histological characterist...
Environmental arsenic exposure, through drinking contaminated water, is a significant risk factor for developing vascular diseases and is associated with liver portal hypertension, vascular shunting, and portal fibrosis through unknown mechanisms. We found that the addition of low doses of arsenite to the drinking water of mice resulted in marked pathologic remodeling in liver sinusoidal endoth...
Larval zebrafish (Danio rerio) of two different age classes ("swim-up" larvae, 9 days old; "free-swimming" larvae, 21 days old) were exposed to either an endurance/continuous training or interval training. Control animals were kept in stagnant water. A comparison of cardiac activity of trained (either endurance or interval) and untrained animals at the end of the training regime revealed no dif...
BACKGROUND AND AIMS Targeting the early mechanisms in exercise-induced arterial hypertension (which precedes resting arterial hypertension in its natural history) may improve cardiovascular morbidity and mortality in COPD patients. Capillary rarefaction, an early event in COPD before vascular remodeling, is a potential mechanism of exercise-induced and resting arterial hypertension. Impaired tr...
Objectives: A correlative study on data from 14 women with unilateral chronic shoulder pain was undertaken. Methods: Data were obtained on evoked pain and pressure-pain thresholds [PPTs] changes upon muscle exertion and biopsy findings on capillary density and muscular pathology. The PPTs were measured in the trapezius muscle, before and after a static abduction endurance test of the shoulder [...
Microvascular exchange in the liver is governed by fenestrations in sinusoidal endothelial cells and can be manipulated pharmacologically. Microvascular exchange is affected in alcoholic liver disease and cirrhosis, the former leading to a loss of fenestrae, the latter to sinusoidal capillarization and thereby to loss of liver function in disease.
