اثر دو ماه سبک زندگی کم تحرک بر بیان ژنی شاخص های موثر در اضافه وزن و سلامت عروق در مردان ۴۰- ۵۵ سال
زمینه و هدف: میانسالی با تغییراتی در سطح شاخص های ژنتیکی و فیزیولوژیک موثر در چاقی و سلامت عروقی همراه است که adrenergic receptor beta 2 (adrb2) و angiotensin converting enzyme (ace) از جمله آنها می باشد، لذا هدف از تحقیق حاضر بررسی اثر دو ماه سبک زندگی کم تحرک بر بیان ژنی adrenergic receptor beta 2 (adrb2) و angiotensin converting enzyme (ace) و نیز شاخص های فیزیولوژیک در مردان 40- 55 سال می ...
ACE inhibitor drugs decrease mortality by up to one-fifth in cardiovascular patients. Surprisingly, there are reports dating back to 1979 suggesting the existence of endogenous ACE inhibitors. Here we investigated the clinical significance of this potential endogenous ACE inhibition. ACE concentration and activity was measured in patient's serum samples (n = 151). ACE concentration was found to...
BACKGROUND Chronic treatment with high doses of angiotensin-converting enzyme (ACE) inhibitors prolongs survival after myocardial infarction. Since the plasma renin-angiotensin system (RAS) is not consistently activated in the chronic phase after myocardial infarction, the beneficial effects of ACE inhibition have been attributed, in part, to inhibition of an activated tissue RAS. However, a re...
Angiotensin-converting enzyme (ACE) inhibitors reduce the progression of atherosclerosis in animal models and reinfarction rates after myocardial infarction in humans. Although expression of components of the renin-angiotensin system has been reported in human coronary arteries, no data regarding their presence in carotid arteries, a frequent site for the occurrence of atherosclerosis plaques, ...
Previous studies suggest that while lung angiotensin converting enzyme (ACE) activity is reduced during chronic hypoxia, inhibitors of ACE attenuate hypoxic pulmonary hypertension. In an attempt to explain this paradox we investigated the possibility that whole lung ACE activity may not reflect local pulmonary vascular ACE expression. The experimental approach combined in vivo hemodynamic studi...
A common polymorphism of the angiotensin-converting enzyme (ACE) gene (ACE in humans, Ace in mice) is associated with differences in circulating ACE levels that may confer a differential risk for cardiovascular diseases. To study the effects of genetically determined changes in Ace gene function within a defined genetic and environmental background, we have studied mice having one, two, or thre...
The article analyzes network effects on the German GSM mobile telephony market. The authors use an ACE-approach to examine how a new competitor can successfully gain ground in the market with a discount-pricing strategy. In particular they study the impact of several elements of a mobile phone contract like on-net-, landlineor off-net-fees on the competitor’s market share. It turns out that it ...
Angiotensin-converting enzyme (ACE) is a zinc-dependent peptidase responsible for converting angiotensin I into the vasoconstrictor angiotensin II. However, ACE is a relatively nonspecific peptidase that is capable of cleaving a wide range of substrates. Because of this, ACE and its peptide substrates and products affect many physiologic processes, including blood pressure control, hematopoiesi...
Angiotensin-I-converting enzyme (ACE) inhibitors are an important class of antihypertensives whose action on the human organism is still not fully understood. Although it is known that ACE especially cleaves COOH-terminal dipeptides from active polypeptides, the whole range of substrates and products is still unknown. When analyzing the action of ACE inhibitors, effects of genetic variation on ...
The enormous benefits of inhibition of ACE demonstrate that manipulation of the metabolism of peptide hormones is a valuable therapeutic strategy for cardiovascular disease. Recent attempts to expand these benefits have combined ACE inhibition with inhibition of other peptidases such as neutral endopeptidase (NEP) in a single molecule, a strategy known as vasopeptidase inhibition. NEP metaboliz...
