BACKGROUND Subjects in the upper-normal range of arterial pressure have an excess cardiovascular risk, which suggests that other factors, such as impaired autonomic regulation, might be implicated. This study was designed to assess whether noninvasive markers of cardiac and vascular autonomic regulation might already be altered in subjects with high-normal arterial pressure levels. METHODS AN...
Background: Many physical and mechanical phenomena occur during the acupuncture and tuina regime, and pressure is one of the most basic mechanical phenomena. Objectives: To understand the cellular bio-physical mechanism of basic mechanical stimulation via acupuncture and tuina by investigating the effect of different in vitro pressures on the cel...
The With no Lysine [K] (WNK) family of enzymes are central in the regulation of blood pressure. WNKs have been implicated in hereditary hypertension disorders, mainly through control of the activity and levels of ion cotransporters and channels. Actions of WNKs in the kidney have been heavily investigated, and recent studies have provided insight into not only the regulation of these enzymes bu...
Angiotensin II, acting through type 1 angiotensin (AT(1)) receptors, has potent effects that alter renal excretory mechanisms. Control of sodium excretion by the kidney has been suggested to be the critical mechanism for blood pressure regulation by the renin-angiotensin system (RAS). However, since AT(1) receptors are ubiquitously expressed, precisely dissecting their physiological actions in ...
The isolated perfused rat kidney experiment was introduced in 1959 for studying the regulation of renal blood flow and is recognized as a valuable preparation for studying physiological and biochemical aspects of renal function such as hemodynamics, glomerular filtration rate (GFR) and overall handling of fluids. Dose-response curves are obtained by injection of bolus doses of drugs into the pe...
