The etfect of activating the renin-angietensin system on the metabolism of angiotensins (ANGs) in normotesusiye human plasma was inyestigated. In normotensiye supine human plasma, four peptides with in vitro angietensin I-conyerting enzyme (ACE) inhibitory activity which correspond to the sequence of ANG (3-8), ANG (4-8), ANG (S-8), and ANG (3--4) existed at a concentration of >39 frnellml of p...
Angiotensin II (Ang II) plays an important role in the onset and development of cardiac remodelling associated with changes of autophagy. Angiotensin1-7 [Ang-(1-7)] is a newly established bioactive peptide of renin-angiotensin system, which has been shown to counteract the deleterious effects of Ang II. However, the precise impact of Ang-(1-7) on Ang II-induced cardiomyocyte autophagy remained ...
زمینه و هدف: از پارامترهای کیفی احتراق سوخت, اندیس دیزل میباشد که نشاندهندهی درجهی آرامسوزی و کیفیت سوخت دیزل است. یکی از روشهایی که بدون صرف هزینه و زمان زیاد میتوان این پارامتر را اندازهگیری نمود استاندارد astm d 611 است. روش بررسی: در این تحقیق از هفت نوع روغنگیاهی (ذرت، سویا، سبوس برنج، هسته انگور، زیتون، آفتابگردان و کلزا) برای تولید سوخت بیودیزل با استفاده از الکل اتانول و به روش...
We recently demonstrated that Angiotensin-(3-4) [Ang-(3-4)], an Ang II-derived dipeptide, overcomes inhibition of plasma membrane Ca(2+)-ATPase promoted by nanomolar concentrations of Ang II in basolateral membranes of renal proximal tubule cells, with involvement of a so far unknown AT(2)R-dependent and NO-independent mechanism. The present study investigates the signaling pathway triggered by...
Previous studies have demonstrated that augmentation of intrarenal angiotensin II (ANG II) levels during ANG II induced hypertension involves both endogenous formation and accumulation of circulating ANG II. The present work extends these findings and determines whether accumulation of infused ANG II in the kidney requires AT1 receptor activation by using Val5-ANG II as the infused peptide. Mal...
Angiotensin II (Ang II) is a critical effector in the renin-angiotensin system (RAS), which modulates cardiovascular homeostasis, and the matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) related metabolism of extracellular matrix (ECM). Angiotensin(1-7) [Ang(1-7)] is another bioactive peptide in the RAS and is considered to have opposite effects to Ang...
We previously demonstrated the substantial capacity for angiotensin (ANG) II formation in the interstitium of the dog heart in vivo. The current study tested the hypothesis that interstitial fluid (ISF) bradykinin (BK) is influenced by ANG II formation. Four microdialysis probes were inserted into the left ventricular myocardium of eight open-chest anesthetized dogs. The probe effluent was coll...
Angiotensin (ANG) II exerts a negative modulation on insulin signal transduction that might be involved in the pathogenesis of hypertension and insulin resistance. ANG-(1-7), an endogenous heptapeptide hormone formed by cleavage of ANG I and ANG II, counteracts many actions of ANG II. In the current study, we have explored the role of ANG-(1-7) in the signaling crosstalk that exists between ANG...
In several models of angiotensin II (ANG II) dependent hypertension, intrarenal ANG II levels increase to a much greater extent than the circulating levels even though the renal renin levels are decreased. The 2-kidney-1-clip (2K1C) Goldblatt rat model is particularly intriguing because hypertension develops in the presence of an intact kidney which would be expected to maintain sodium balance ...
Recently, a new derivative of angiotensin (Ang) II, called "Ang A," has been discovered to be present in plasma of healthy humans and, in increased concentrations, in end-stage renal failure patients. The objectives of the study were to investigate the blood pressure and renal hemodynamic responses to Ang A in normotensive and hypertensive rats and in genetically modified mice and the binding p...
