BACKGROUND Although abnormal L-arginine NO signaling contributes to endothelial dysfunction in the aging cardiovascular system, the biochemical mechanisms remain controversial. L-arginine, the NO synthase (NOS) precursor, is also a substrate for arginase. We tested the hypotheses that arginase reciprocally regulates NOS by modulating L-arginine bioavailability and that arginase is upregulated i...
چکیده : مقدمه : ابتلا به آترواسکلروز در بیماران دیابتی بیشتر از افراد سالم می باشد . هموسیستئین می تواند به عنوان یکی از عوامل خطرزای آترواسکلروز مطرح با شد . آنزیم لستین کلسترول آسیل ترنسفراز نقش مهمی را در پاک سازی کلسترول آزاد در بافت ها از طریق عملکرد hdl-c بر عهده دارد .هدف از این مطالعه تعیین سطح فعالیت لستین کلسترول آسیل ترنسفراز (lcat activity ) در بیماران دیابتی نوع 2 در مقایسه با افر...
Inhibitors of Rho kinase (ROCK) have potential therapeutic applicability in a wide range of diseases, such as hypertension, stroke, asthma and glaucoma. In a previous article, we described the lead discovery of DL0805, a new ROCK I inhibitor, showing potent inhibitory activity (IC50 6.7 μM). Herein, we present the lead optimization of compound DL0805, resulting in the discovery of 24- and 39-fo...
The present study investigated the vasorelaxant action of the aqueous leaves extract of Persea americana on isolated rat aorta. The results showed that the extract produced significant vasorelaxation and that the effect is dependent on the synthesis or release of endothelium-derived relaxing factors (EDRFs) as well as the release of prostanoid. The extract also reduced vasoconstriction probably...
We studied the effects of MAbR15.7, an antibody directed against the common beta-chain (CD-18) of a family of neutrophil adherence glycoproteins, on endothelial dysfunction and myocardial injury in a model of myocardial ischemia and reperfusion in cats. Pentobarbital-anesthetized cats were subjected to 1.5 h occlusion of the left anterior descending coronary artery (LAD) and 4.5 h of reperfusio...
