هدف: سقط مکرر خودبخودی (rpl) حالتی است که در آن بیش از ? یا ? بار متوالی جنین خودبخود سقط گردد. 5/0 تا 5 درصد خانم های باردار درگیر سقط مکرر هستند. هدف این تحقیق بررسی ارتباط بین پلی مرفیسم های g1958a و g894t در ژنهایmthfd1 و enos با سقط مکرر است. روش کار: از روش rflp- pcr برای شناسایی پلی مرفیسم ها استفاده شد. نمونه ها شامل 100 زن با سابقه سقط مکرر و 50 زن زایا و بدون سابقه سقط بودند که بعنوا...
Background: Nitric oxide (NO) produced by endothelial NO synthase (eNOS) mediates a large range of processes, and abnormality in the production of NO has been implicated in diabetic complications including diabetic nephropathy (DN). G894T polymorphism in the eNOS gene has been shown to decreased activity the NO levels of plasma. The association between eNOS Glu298Asp gene polymorphism and DN ri...
background: objective: the aim of this study was to evaluate the expression of enos in the fts of women with tep. materials and methods: in this case-control study, a total number of 30fts samples were obtained from three groups including: 10 fts of women that bearing an ep, 10 fts from the non-pregnant women at luteal phase of the menstrual cycle, and 10 fts of healthy pregnant women (n=10...
background: non obstructive azoospermia (noa) is one of the causes of male infertility in which spermatogenesis process is disturbed. recent studies suggested the possible role of endothelial nitric oxide synthase (enos) in spermatogenesis process. objective: the aim of the present study is to evaluate the expression of enos in human testicular tissue in men with noa and men with normal spermat...

چکیده سابقه و هدف: بیماری عروق کرونر به عنوان رایج ترین فرم بیماری های قلبی و عروقی، یک بیماری چند فاکتوری با اتیولوژی پیچیده بوده که مجموعه ای از فاکتورهای محیطی و ژنتیکی در بروز آن تاثیر گذار می باشد. از جمله مهم ترین ژن های شناخته شده مرتبط با بیماری های قلبی می توان به ژن نیتریک اکسید سنتاز 3 (nos3) اشاره نمود.از آن جایی که نیتریک اکسید یک مولکول کلیدی تنظیمی با تاثیرات گسترده متابولیک، عرو...
We examined the hypothesis that contraction of the carotid arteries to serotonin is normally inhibited by endothelial NO synthase (eNOS) and is enhanced in mice lacking the gene for eNOS. Because the influence of eNOS may vary with the sex of the mouse, we also tested whether responses to serotonin were dependent on sex. We studied carotid arteries in vitro from littermate control (eNOS(+/+)) m...
Endothelial nitric oxide synthase (eNOS) is a multifunctional enzyme with roles in diverse cellular processes including angiogenesis, tissue remodeling, and the maintenance of vascular tone. Monomeric and dimeric forms of eNOS exist in various tissues. The dimeric form of eNOS is considered the active form and the monomeric form is considered inactive. The activity of eNOS is also regulated by ...
ABSTRACT Background and Objective: Genetic variations in the gene encoding endothelial nitric oxide synthase (eNOS) enzyme affect the susceptibility to cardiovascular disease. Identification of the way these changes affect eNOS structure and function in laboratory conditions is difficult and time-consuming. Thus, it seems essential to ...
abstract background: nitric oxide (no) is a molecule that incorporates in many physiological processes of female reproductive system. recent studies suggested the possible role of endothelial isoform of nitric oxide synthase (enos) enzyme in female infertility. objective: the aim of this study is to evaluate the expression of endothelial nitric oxide synthase in endometrial tissue of women with...
