BACKGROUND The renin-angiotensin system is a widely studied hormonal system that comprises substrate-enzyme interactions, the end result of which is the production of the active peptide angiotensin II. Because angiotensin II affects blood pressure control, sodium and water homeostasis, and cardiovascular function and structure, a great deal of research effort has been directed toward blocking t...

BACKGROUND The renin-angiotensin system (RAS) is present in human placental tissue and participates in regulation of maternal-fetal blood flow during pregnancy. RAS expression in placental tissue is regulated by various hormones and is altered in various disease conditions. An in vitro system is needed to further investigate regulation of the placental RAS. To this end, we studied RAS expressio...

Dietary salt intake is a major determinant of the activation state of renin-angiotensin-aldosterone system. Given the important role of the renin-angiotensin-aldosterone system in plaque accumulation, we investigated its role in the development of atherogenesis associated with sodium intake in apolipoprotein E knockout mice. Six-weeks of a low-salt diet (containing 0.03% sodium) resulted in a 4...

abstract objectives: interruption of rennin-angiotensin-aldosterone system has become a leading therapeutic strategy in the treatment of diabetic nephropathy however, aceis and arbs do not uniformly suppress the rennin-angiotensin-aldosterone system. plasma aldosterone levels are elevated in a group of patients despite therapy and this phenomenon known as aldosterone escape or aldosterone break...

• The role of the renin-angiotensin system in the control of arterial blood pressure and aldosterone secretion has been studied extensively in homeostasis, hypertensive disease, and edematous states. For many years it has been realized that the availability of effective blocking agents for renin or for angiotensin II might help greatly in the study of this system and might have important value ...

The dysregulation of renin-angiotensin-system (RAS) plays a pivotal role in hypertension and the development related target organ damage (TOD). main goal treating is represented by long-term reduction cardiovascular (CV) risk. RAS inhibition either angiotensin converting enzyme (ACE)-inhibitors or type 1 Angiotensin II receptors blockers (ARBs), reduce incidence CV events hypertensive patients....
