It was investigated to what degree left atrial distension augments the hypotensive effects of a 15-min moderate antiorthostatic maneuver in humans. Ten healthy males underwent a posture change from upright seated (Seat, legs horizontal) to supine (Su

The mechanism(s) by which acetylcholine (ACh) increases atrial vulnerability to reentry and maintains its activity for longer durations remains poorly defined. In the present study we used high-resolution activation maps to test the hypothesis that A

The signal transduction of ischemic preconditioning involves activation of endogenous receptor-based systems, including alpha 1-adrenoceptors and adenosine receptors. Whereas preconditioning protects against ischemia-reperfusion injury, it is unknown

The decreased contraction amplitude of isolated cardiac myocytes from guinea pigs exposed to lipopolysaccharide (LPS) was reported to be partially reversed by nitro-L-arginine methyl ester (L-NAME), an inhibitor of nitric oxide synthase (NOS) [Brady,

The present study tested the hypothesis that adenosine is involved in mediating the hyperemic response of the newborn brain to hypoglycemia. By use of the cranial window and microdialysis-H2 clearance methodologies, changes in the diameter of pial ar

Although intracoronary administration of the complement component, C5a, produces deleterious effects on regional coronary blood flow and segmental ventricular function, it is unclear whether a direct myocardial action contributes to the dysfunction i

Experimental and clinical data suggest that even a brief period of intestinal ischemia followed by reperfusion initiates a sequence of events that include release of inflammatory mediators and multiorgan failure. In this study, 41 rats were subjected

Sodium and the renin-angiotensin system (RAS) participate in the regulation of cardiovascular function, in part via activation of central nervous system (CNS) mechanisms. Because intraventricular (IVT) administration of either hypertonic sodium chlor

The neurohormonal and sympathetic nervous system responses to injection of hypertonic NaCl (1.5 M) into the cisterna magna were investigated in morphine-pentobarbital-anesthetized dogs (n = 8). Mean arterial blood pressure (MAP), heart rate (HR), and

An angiotensin II receptor antagonist, [Sar1-Ala8]angiotensin II (saralasin), was infused at 60 (microgram/kg)/h into cats to examine its effect in hemorrhagic shock. Aprotinin (1,000 (KIU/kg)/h) was also administered to cats to determine how kinin i
