Lipid peroxidation and nitric oxide inactivation in postmenopausal women.
OBJECTIVE To assess the effect of endogenous estrogens on the bioavailability of nitric oxide (.NO) and in the formation of lipid peroxidation products in pre- and postmenopausal women. METHODS NOx and S-nitrosothiols were determined by gaseous phase chemiluminescence, nitrotyrosine was determined by ELISA, COx (cholesterol oxides) by gas chromatography, and cholesteryl linoleate hydroperoxid...
متن کاملLipid Peroxidation Inhibition, Superoxide Anion and Nitric Oxide Radical Scavenging Properties of Thymus daenensis and Anethum graveolens Essential Oils
Background: Safety and efficacy of the synthetic antioxidants used in the food industry are frequently questioned because such antioxidants are unstable and highly volatile, therefore, interest in finding naturally occurring antioxidants that have the potential to protect human beings from damage induced by oxidative stress has intensified. Objective: Bioactivities of Thymus daenensis and Ane...
متن کاملLipid Peroxidation and Nitric Oxide Levels in Male Smokers' Spermatozoa and their Relation with Sperm Motility
BACKGROUND Nitric oxide (NO) is synthesized from L-arginine by a family of enzymes known as nitric oxide synthases. Low concentrations of NO is essential in biology and physiology of spermatozoa, but high amounts of NO is toxic and has negative effects on sperm functions. Moreover, sperm membrane contains high concentrations of polyunsaturated fatty acids that are highly susceptible to oxidativ...
متن کاملNitric oxide and membrane lipid peroxidation in photosynthetic and non-photosynthetic organisms under several stress conditions
INTRODUCTION Oxidative damage to lipids was characterized in terms of the nature of the oxidant, the type of lipid, and the severity of the oxidation (Simontacchi et al., 2011). Even though malondialdehyde detection with the thiobarbituric acid reactive substances test (TBARS) is the most currently used assay for the determination of lipid oxidation, it is unspecific since the reaction can be r...
متن کاملNitric oxide levels and lipid peroxidation in plasma of patients with gastric cancer.
BACKGROUND The aim was to investigate the levels of malondialdehyde and total NO(2)(-) plus NO(3)(-) marker for NO(*) generation in gastric carcinoma and to correlate their levels with the cancer stage. METHOD The pretreatment plasma samples were obtained from 38 patients with gastric cancer (seven patients at stage II, 19 at stage III and 12 at stage IV). Nitrite (NO(2)(-)) and nitrate (NO(3...
