Influence of blood viscosity to cerebral blood flow in older humans compared to young subjects
(Elsevier B.V., 2012-01-01)
Objective: Since blood viscosity (BV) is one of the most important factors determining blood flow, this study aimed to investigate the possible correlation between increased blood viscosity and reduction of regional cerebral ...
Turbulent blood flow plays an essential localizing role in the development of atherosclerotic lesions in experimentally induced hypercholesterolaemia in rats
(BLACKWELL PUBLISHING, 2008)
Taking into account that atherosclerosis is a focal disease and high levels of plasma cholesterol are closely correlated with its pathogenesis, it is a challenge to explain how equal concentrations of cholesterol bathing ...
Haemodynamic effects of hypothalamic disconnection in anaesthetized rats
The aim of the present study was to analyse the haemodynamic effects induced by the hypothalamic disconnection (HD) caudal or rostral to the paraventricular nucleus of the hypothalamus (PVN). Mean arterial pressure (MAP), ...
O óxido nítrico (NO) no controle neural da pressão arterial: Modulação da transmissão glutamatérgica no NTS
The neuromodulatory effect of nitric oxide (NO) on glutamatergic transmission within the NTS related to cardiovascular regulation has been widely investigated. Activation of glutamatergic receptors in the NTS stimulates ...
