Dose and Time-Dependent Effects of Caffeine on Cardiovascular Changes Induced by Adenosine

open access: yesBrazilian Archives of Biology and Technology, 2023
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

Quantification of renal blood flow with contrast-enhanced ultrasound [PDF]

open access: yes, 2001
OBJECTIVESThe goal of this study was to determine the ability of contrast-enhanced ultrasound (CEU) to quantify renal tissue perfusion.BACKGROUNDThe kinetics of tracers used to assess renal perfusion are often complicated by countercurrent exchange ...

Ornipressin in the treatment of functional renal failure in decompensated liver cirrhosis [PDF]

open access: yes, 1991
In 11 patients with decompensated cirrhosis and deteriorating renal function, the effect of the vasoconstrictor substance 8-ornithin vasopressin (ornipressin; POR 8; Sandoz, Basel, Switzerland) on renal function, hemodynamic parameters, and humoral ...

Low Arginine Plasma Levels do not Aggravate Renal Blood Flow after Experimental Renal Ischaemia/reperfusion [PDF]

open access: yes, 2001
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]

open access: yes, 1999
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 ...
