Background: Resveratrol is a natural polyphe- nolic compound, synthesized by plants as a phytoalexin and protects against ultraviolet radiation and fungal infection. Nitric oxide is formed from L-arginine through nitric oxide synthases (NOS), a group of enzymes that structurally resemble cytochrome P-450 reductase. In females, circulating NO is increased during follicle development and decrease...
Introduction: Salivary biomarkers may elucidate orodental inflammatory processes. Nitric oxide (NO) may help us to diagnose such changes . Methods: In this case-control study, all referral patients diagnosed with 130% sites were enrolled as generalized mild to moderate periodontitis group (PG). All PG and healthy control group (CG)’ individuals underwent scaling and root planning (SRP)...
Introduction: Despite the beneficial roles of nitric oxide, its excessive synthesis causes neurodegenerative diseases. Therefore, the aim of the present study was to compare the nitric oxide changes in the hippocampal tissue and the pain sensation of male Parkinson's rats after 6 weeks of continuous and interval training. Methods: In this experimental study, 24 Wistar male rats were used. Rats...
ischemia reperfusion injury (ir injury) is a common problem in clinical conditions. researches have frequently revealed that atp- sensitive potassium (katp) channels and nitric oxide plays a role in protection against ischemic injury in skeletal muscle. the present study aimed at evaluating the possible link between this two pathways. sixty-eight male wistar rats, were pretreated with saline, d...
The reaction between reducing sugars and protein free amines, known as the Maillar reaction results in the formation of advanced glycation endproducts (AGEs). AGE modification changes the structure of proteins to amyloid cross-beta structure. These protein structures can activate receptors known as RAGE on glial cells (microglia and astrocytes), and induce the expression of inducible nitric oxi...
Abstract Bachground and objectives: Epidemiological studies have shown that using tobacco products is one of the main factors in forming malignancies in various tissues of the body. There is more than 600 μgr nitric oxide radical (NO°) in gas phase in each cigarette with fresh smoke. Hence, oxidation of nitrogen components in tobacco, more than 100 μgr of atmospheric NO°is produce...
introduction: some studies have demonstrated the potential of herbal drugs for the treatment of various diseases associated with impaired vascular nitric oxide (no). for diagnosis of the mechanism of these herbal plants, it seems necessary to evaluate the herbal extracts on the endothelium cell. the aim of the study was to investigate the effect of extract of trigonella foenum-graecum (t.foenum...
