In angiotensin type 1 receptor-blocked rats, renal interstitial (RI) administration of des-aspartyl(1)-angiotensin II (Ang III) but not angiotensin II induces natriuresis via activation of angiotensin type 2 receptors. In the present study, renal function was documented during systemic angiotensin type 1 receptor blockade with candesartan in Sprague-Dawley rats receiving unilateral RI infusion ...

INTRODUCTION We recently demonstrated that angiotensin II (Ang II) was involved in the etiology of Parkinson's disease (PD) via induction of apoptosis of dopaminergic neurons, but the mechanisms are not completely elucidated. Here, we asked whether mitochondrial-dependent mechanisms contributed to the Ang II-induced dopaminergic neuronal apoptosis. MATERIALS AND METHODS CATH.a cells were incu...

angiotensin-ii is a multifunctional hormone that regulates blood pressure, plasma volume, neuronal functions, electrolyte balance, thrust and various other vital mechanisms. it acts through its receptors at 1 and at 2 . the involvement of angiotensin-ii and its receptors in cognition is still ambiguous. therefore, the present study was designed to investigate the effect of angiotensin-ii (2 μg/...

UNLABELLED Biomarkers are increasingly used to provide decision making data early in phase I by showing Proof of Mechanism or Proof of Concept (PoM/PoC). For antihypertensive agents, the administration of multiple doses (md) to hypertensive patients is assumed to be necessary for an early go/no-go decision. We compared the effects of an Angiotensin II receptor antagonist (ARA) on Plasma Renin a...

Background Weight reduction is a lifestyle intervention that has been introduced for prevention and management of chronic kidney disease (CKD). We investigate the additive anti-proteinuric effect of weight reduction on the usage of angiotensin II receptor blockers (ARBs) and its potential mechanisms in hypertensive CKD patients. Methods This study is a subanalysis of data from an open-label, ...

The renin-angiotensin-aldosterone system plays a major role in the pathophysiology of hypertension and closely related cardio- and cerebrovascular events. Although both angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor antagonists (angiotensin receptor blockers; ARBs) are equally important in the treatment of hypertension, according to the results of recent years, there mi...

The recently approved angiotensin II receptor blocker, azilsartan medoxomil (AZL), was determined spectrophotometrically and spectrofluorimetrically in its combination with chlorthalidone (CLT) in their combined dosage form. The UV-spectrophotometric technique depends on simultaneous measurement of the first derivative spectra for AZL and CLT at 286 and 257 nm, respectively, in methanol. The sp...

The role of renin-angiotensin system inhibitors (ACE-inhibitors) or angiotensin receptor blockers (ARB) in the renal transplant recipients (RTRs) is incompletely defined and according to the current guidelines they should be initiated after six months post-transplantation. The aim of the present paper is to evaluate the efficiency and safety of early (within six months post-transplantation) ver...

Macula densa cyclooxygenase 2 (COX-2)-derived prostaglandins serve as important modulators of the renin-angiotensin system, and cross-talk exists between these two systems. Cortical COX-2 induction by angiotensin-converting enzyme (ACE) inhibitors or AT(1) receptor blockers (ARBs) suggests that angiotensin II may inhibit cortical COX-2 by stimulating the AT(1) receptor pathway. In the present s...
