background: migraine is a chronic  neurological  disorder, characterized  by recurrent  moderate to severe headaches. worldwide migraine a=ects nearly 15%. studies suggest that genes involved in the production of nitric oxide (no) may act as genetic  factors for migraine. no synthase  3 (nos3) by expressing  enzyme nos regulates  endothelial  derived no. one  class of  medications   used  as  f...

introduction: ischemia/reperfusion (ir) injury involves a complex interrelated sequence of events. high levels of nitric oxide (no) are generated with inducible form of nitric oxide synthase (inos) leading to the renal ir injury and glutathione (gsh) depletion. the present study was designed to investigate the effect of l-nil (n6- (1-iminoethyl)-l- lysine.hydrochloride), a selective inhibitor o...

Vasoplegic shock refractory to vasopressors is associated with significant morbidity and mortality. Catecholamine driven therapies are first-line in the management of vasoplegic shock. Research regarding use non-catecholamine agents setting lacking. Methylene blue has multiple off-labelled indications for use, but recently been suggested have a role treating mediated by dysregulation nitric oxi...

Background and Purpose: Soleshine is a polyherbal preparation established in the market for the treatment of cracks and tinea pedis, which is applied externally. This preparation is composed of the extracts of indigenous plants, namely Azadirachta indica, Lawsonia alba, and Shorea robusta, mixed with castor oil and sesame oil. In the present study, an attempt was made to identify the constituen...

indirect evidence suggests that estrogen is involved in the etiology of breast cancer. estrogen is also thought to modulate nitric oxide (no) in human breast tumor tissue via regulation of inducible nitric oxide synthase (inos). objectives of this study were to determine whether estradiol (e2) affects inos expression level in breast cancer cells and to study the effect of various concentrations...

To understand how peppermint responds to different LED light qualities during the early vegetative phase, peppermints were illuminated with three conditions (RB = Red/Blue, RGB Red/Green/Blue, SUN artificial sunlight closely resembling terrestrial spectrum between 380 and 780 nm) in an automated vertical cultivation system. RB resulted compact growth, whereas both green-containing lighting indu...

background: salivary gland tumors (sgt) are rare lesions with uncertain histopathology. one of the major signaling pathways that participate in the development of several tumors is protein kinase a. in this pathway, glycogen synthase kinase β (gsk3β) and camp responsive element binding protein (creb3) are two genes which are supposed to be down regulated in most human tumors. the expression lev...

nitric oxide (no) is thought to be involved in spatial learning and memory in several brain areas such as hippocampus. this study examined the effects of post-training intrahippocampal microinjections of 1400w as a selective inos inhibitor on spatial memory, in anesthetized and non-anesthetized situations in rats. in the present work, 4-day training trials of animals were conducted. spatial mem...
