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...

cardiovascular disorders continue to constitute major causes of morbidity and mortality in diabetic patients. in this study, the effect of chronic administration of sesame (sesamum indicum l) seed feeding was studied on aortic reactivity of streptozotocin (stz)-diabetic rats. male diabetic rats received sesame seed-mixed food at weight ratios of 3% and 6% for 7 weeks, one week after diabetes in...

background and objective: cardiovascular disorders continue to constitute major causes of morbidity and mortality in diabetic patients. in this study, the effect of chronic administration of tribulus terrestris (tt) feeding was studied on aortic reactivity of streptozotocin (stz)-diabetic rats and some underlying mechanisms were investigated.    materials and methods: male diabetic rats receive...

Background: In vitro culture of ovarian follicles may preserve fertility in women with premature ovarian failure due to cancer .It seems that creation a condition that could maintain cellular communications and supports growth of follicles to produce mature oocytes appear to be essential. Nitric oxide (NO) has been recently shown to act with a dual action in mouse oocyte meiotic maturation depe...

Airways inflammation has been associated with increased nitric oxide (NO) in the exhaled breath. It was, therefore, questioned whether exhaled NO could act as an indicator of the severity of airways inflammation in the chronic suppurative lung diseases cystic fibrosis (CF) and bronchiectasis. NO levels in a single exhalation were measured using a chemiluminescence analyser. Thirty-six patients ...

The stimulation of excitatory amino acid receptors in the cerebellar cortex results in the Ca2+/calmodulin-dependent activation of nitric oxide synthase. This leads to an increase in tissue levels of cGMP following the interaction of nitric oxide with soluble guanylyl cyclase. The cerebellar cortex has the highest levels of nitric oxide synthase and cGMP in the brain; however, the levels of gua...

Bimetallic MOF Photocatalysts Ti atoms rapidly replace Zr in UiO-66-NH2 crystal under microwave irradiation. The formed congenetic “shell-core” structure and the introduced electron acceptor, Ti, enhance photocatalytic nitric oxide (NO) removal. Furthermore, synergy of NO photooxidation subsequent NO2 adsorption not only removes efficiently an environmentally friendly fashion, but also provides...

background: clomiphene citrate (cc) is the first line agent used for ovulation induction in patients with polycystic ovarian syndrome (pcos). however, there is marked discrepancy between the ovulation and pregnancy rates achieved, which may be attributed to the undesirable effect of cc on cervical mucus and endometrium. objective: the aim of this study was to evaluate the effect of isosorbid mo...
