Dose and Time-Dependent Effects of Caffeine on Cardiovascular Changes Induced by Adenosine
Adenosine is an important regulator within the cardiovascular system and modulates various processes through four distinct G protein-coupled receptors (A1, A2A, A2B, and A3), causing hypotension and reduced renal blood flow, which contributes to ischemia

Low Arginine Plasma Levels do not Aggravate Renal Blood Flow after Experimental Renal Ischaemia/reperfusion [PDF]
Background: ischaemic renal dysfunction is present in many clinical settings, including cardiovascular surgery. Renal hypoperfusion seems to be the most important pathophysiologic mechanism.

Altered renal hemodynamics and impaired myogenic responses in the fawn-hooded rat [PDF]
The present study examined whether an abnormality in the myogenic response of renal arterioles that impairs autoregulation of renal blood flow (RBF) and glomerular capillary pressure (PGC) contributes to the development of ...
