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 ...
Foetal echoencephalography and Doppler ultrasonography of the middle cerebral artery in canine foetuses
(2013-03-01)
Objectives: This study aimed to evaluate the characteristics of the brain and vascular indicesof the middle cerebral artery of canine foetuses. Methods: Twenty-five bitches were selected. Tissue development, echogenicity, ...
Anteroventral third ventricle lesions impair cardiovascular responses to intravenous hypertonic saline infusion
(Elsevier B.V., 2005-01-15)
The anteroventral third ventricle (AV3V) region is a critical area of the forebrain, acting on fluid and electrolyte balance and maintaining cardiovascular homeostasis. The purpose of this study was to determine the effects ...
Photobiomodulation 30 min or 6 h Prior to Cycling Does Not Alter Resting Blood Flow Velocity, Exercise-Induced Physiological Responses or Time to Exhaustion in Healthy Men
(2021-01-15)
Purpose: The aim of the current study was to investigate the effects of photobiomodulation therapy (PBMT) applied 30 min or 6 h prior to cycling on blood flow velocity and plasma nitrite concentrations at rest, time to ...
A mathematical model for wave propagation in elastic tubes with inhomogeneities: Application to blood waves propagation
(Elsevier B.V., 2007-12-15)
We study the propagation of waves in an elastic tube filled with an inviscid fluid. We consider the case of inhomogeneity whose mechanical and geometrical properties vary in space. We deduce a system of equations of the ...
Total and regional coronary blood flow during acute coronary occlusion in anaesthetized and conscious dogs
(1974)
Total and regional coronary blood flow was measured with microspheres labeled with 141Ce or 85Sr before and early after the occlusion of the anterior descending coronary artery. A radial gradient of flow was found in the ...
