There is a lot of uncertainty in the theory hemodynamics. The amount work need to displace blood systemic circulation, exceeds done by left ventricle. With this, recovers increased flow resistance between heartbeats with Womersley number alterations rhythm accompanying electrocardiogram (ECG). Viscoelastic transformation heavily expressed coagulation. must be relationship ECG and transient resi...

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-articular...
