The catastrophic effects of opioids use on public health and the economy are documented clearly in numerous studies. Repeated morphine administration can lead to either a decrease (tolerance) or an increase (sensitization) in its behavioral and rewarding effects. Morphine-induced sensitization is a major problem and plays an important role in abuse of the opioid drugs. Studies reported that mor...
NADPH diaphorase staining neurons, uniquely resistant to toxic insults and neurodegenerative disorders, have been colocalized with neurons in the brain and peripheral tissue containing nitric oxide synthase (EC 1.14.23.-), which generates nitric oxide (NO), a recently identified neuronal messenger molecule. In the corpus striatum and cerebral cortex, NO synthase immunoreactivity and NADPH diaph...
accumulating evidence indicates that aldosterone plays a critical role in the mediation of oxidative stress and vascular damage. nadph oxidase has been recognized as a major source of oxidative stress in vasculature. however, the relation between nadph oxidase in aldosterone-mediated oxidative stress in endothelial cells remains to be ascertained. the present study aimed to investigate the rele...
The cofactor requirements of macrophage nitric oxide (NO.) synthase suggest involvement of an NADPH-dependent flavoprotein. This prompted us to test the effect of the flavoprotein inhibitors diphenyleneiodonium (DPI), di-2-thienyliodonium (DTI), and iodoniumdiphenyl (ID) on the NO. synthases of macrophages and endothelium. DPI, DTI, and ID completely inhibited NO. synthesis by mouse macrophages...
Hyperhomocysteinemia decreases vascular reactivity and is associated with cardiovascular morbidity and mortality. However, pathogenic mechanisms that increase oxidative stress by homocysteine (Hcy) are unsubstantiated. The aim of this study was to examine the molecular mechanism by which Hcy triggers oxidative stress and reduces bioavailability of nitric oxide (NO) in cardiac microvascular endo...
background and objectives: the essential amino acid l-tryptophan can be produced by a condensation reaction between indole and l-serine, catalyzed by b. subtilis with tryptophan synthase activity. application of the tryptophan is widespread in the biotechnology domain and is sometimes added to feed products as a food fortifier. materials and methods: the optimum concentration of the iranian can...
the aim of this study was to investigate the effects of nigella sativa (ns) fixed oil in comparison to dexamethasone (dex) on inducible nitric oxide synthase (inos), peripheral blood eosinophils (pbe), allergen specific serum igg1 and interleukins and airway inflammation in a murine model of allergic asthma. thirty-one mice were divided into four groups. group i (n = 6) served as the control...
the product biofilm by e.coli strain can cause serious problem for human health. catheter is considered to be s suitable place for colonization of microorganisms, so that in %5-10 of patients who used catheter for only one day and also in all patients who used it for over 28 days, this colonization of bacteria is observed on catheter. this study is come out in order to compare biofilm formation...
coq10 and lycopene are isoprenoid compounds with nutraceutical and pharmaceutical benefits. in this study, the effect of concomitant lycopene biosynthesis on coq10 accumulation in transformed escherichia coli dh5α was studied. a lycopene production pathway including geranylgeranyl diphosphate synthase (crte), phytoene synthase (crtb), and phytoene desaturase (crti) from erwinia herbicola was co...
Nitric oxide (NO) influences infarct size after focal cerebral ischemia and also regulates neurogenesis in the adult brain. These observations suggest that therapeutic approaches to stroke that target NO signaling may provide neuroprotection and also enhance brain repair through cell replacement. However, ischemic injury and neurogenesis are both affected differently depending on which isoform ...
