periodontal inflammation is associated with morphological changes in the blood vessels which may influence the regulation of gingival blood flow (gbf). our aim was to adapt the heat provocation test to the human gingiva to assess vascular reactivity in periodontal inflammation. method: gbf was recorded by laser doppler flowmetry before and after heat provocation in healthy volunteers (n = 50). ...

In this paper consider a two-fluid model consisting of a core region of suspension of all the erythrocytes (particles) in plasma (fluid) assumed to be a particle-fluid mixture and a peripheral layer of cell-free plasma (Newtonian fluid), has been proposed to represent blood flow in small diameter tubes with effects of magnetic. The analytical results obtained in the proposed model for effective...

background: angiotensin converting enzyme (ace) upregulation in stromal cells of joints affected by rheumatoid arthritis may lead to higher tissue angiotensin ii that is a vasoconstrictor and mitogen factor. to date, the role of angiotensin ii on regulating blood flow in inflamed joints has not been studied.   methods: acute and chronic joint inflammation was induced in rabbits by intra-articul...
