Nitric oxide has been found to play an important role as a signal molecule in many parts of the organism as well as a cytotocic effector molecule of nonspecific immune response. Nitric oxide is very important functions both in helminthes and mammalian hosts. Nitric oxide may react with proteins and nucleic acids. In addition to binding to heme groups, e.g. of guanylate cyclase, hemoglobin, and ...

The effect of N-acetyl-L-cysteine on interleukin-1beta-induced nitric oxide synthase expression was studied in rat vascular smooth muscle cells to determine if the reduction/oxidation state would modulate cytokine-induced changes. Interleukin-1beta induced the production of nitrite, a stable metabolite of nitric oxide in a time- and dose-dependent manner. Cytokine-induced nitrite production was...

The present study aimed to investigate the possible influence of several inhibitors and blockers on the vascular effect produced by the acute in vitro application of rosuvastatin to phenylephrine-precontracted aortic rings from rats with a semi-solid, cafeteria-style (CAF) diet. It also aimed to examine the effects of rosuvastatin on the expression of endothelial nitric oxide synthase (eNOS), i...

Physiological amounts of this gas are neuroprotective, whereas higher.Nitric oxide nfpa 80 standard for fire doors pdf NO derived from the inducible i...

Inhaled nitric oxide is a selective pulmonary vasodilator used for the treatment of pulmonary hypertension. The potential adverse effects of inhaled nitric oxide are unknown and represent the focus of the present studies. Whereas inhalation of nitric oxide (10 to 100 ppm, 5 h) by Balb/c mice had no effect on the number or type of cells recovered from the lung, a dose-related increase in broncho...

Neuropathic pain is a complication of inflammation, infection or some diseases such as diabetes. Opioids are used as a salvage therapy for neuropathic pain but tolerance restricts their use. In our previous study we have observed an increase of Nitric Oxide in diabetes and in morphine tolerance. This study was performed to clarify the role of inducible nitric oxide synthase, iNOS, and cationic ...

Nitric oxide (NO) has emerged as an important mediator of many physiological functions. Recent reports have shown that NO participates in the wound healing process, however, its role in keloid formation remains unclear. This study aimed to investigate the effect of NO on keloid fibroblasts (KF) and to determine the levels of inducible nitric oxide synthase (iNOS) expression in clinical specimen...

This data article provides additional evidence on gene expression changes in the neuronal and inducible isoforms of nitric oxide synthase in the medial prefrontal cortex following acute stress. Male Wistar rats aged 6-8 weeks were exposed to control or restraint stress conditions for up to four hours in the dark cycle after which the brain was removed and the medial prefrontal cortex isolated b...

The molecular messenger nitric oxide (NO) is synthesized endogenously from L-arginine by three isoforms of the enzyme NO synthase. The isoform most consistently associated with neoplasia is the inducible form, inducible nitric oxide synthase (iNOS). However, the role played by the NO/iNOS system in tumor development is complex, and both promoting and inhibitory effects on neoplasia have been re...
