the aim of this study was to investigate the effects of administering antioxidants, including vitamin c and chitosan on oxidative stress markers in muscle as edible tissues of cyprinus carpio exposed to cadmium chloride. in this experiment, by exposing to 0.2 mg/l cadmium chloride for 21 days, fish were fed a normal diet, diet containing chitosan (1000 mg/kg diet), vitamin c (1000 mg/kg diet) o...

background: consumption of dark chocolate has been often hypothesized to have a role in the prevention of chronic diseases. the objective of this study was to investigate the effects of consumption of dark chocolate (dc) on serum oxidative stress and blood pressure in patients with metabolic syndrome (mets). methods: an 8-week parallel randomized clinical trial involving 114 patients with mets ...

objective(s): silver nanoparticles (ag-nps) are one of the most widely used nanomaterials recently. despite the wide application of nanomaterials, there is limited information concerning their impact on human health and the environment. this study aimed to find the effects of ag-nps (40 nm) on blood serum, liver and kidney tissues of homing pigeons (columbia livia).materials and methods: columb...

background: infertility is defined as the inability to achieve the pregnancy within a year of unprotected intercourse. infertility is a complex issue and different factors such as stress oxidative can be involved in this problem. so, any attempt to neutralize oxidative stress would be helpful in the treatment of infertility. melatonin is a known scavenger of free radicals. objective: the aim of...

background: silicosis is considered an oxidative stress related disease that can lead to the development of lung cancer. in this study, our purpose was to analysis of volatile organic compounds (vocs) in the exhaled breath of workers exposed to silica containing dust and compare peak area of these compounds with silicosis patients and healthy volunteers (smokers and nonsmokers) groups. methods ...

Oxidative stress is related to an imbalance between the production of reactive species and the antioxidant defenses. In essence, oxidative stress has been defined as a disturbance in the pro-oxidant/antioxidant balance, leading to potential damage. It has been suggested that oxidative stress is involved in the etiology of several chronic diseases including cardiovascular disease, diabetes, canc...

SIGNIFICANCE Oxidative stress is considered to be an important component of various diseases. A vast number of methods have been developed and used in virtually all diseases to measure the extent and nature of oxidative stress, ranging from oxidation of DNA to proteins, lipids, and free amino acids. RECENT ADVANCES An increased understanding of the biology behind diseases and redox biology ha...

In vitro cell model studies have shown that oxidative stress may affect beta-cell function. It is unknown whether oxidative stress may affect metabolic health in human fetuses/newborns. In a singleton pregnancy cohort (n = 248), we studied maternal (24-28 weeks gestation) and cord plasma biomarkers of oxidative stress [malondialdehyde (MDA), F2-isoprostanes] in relation to fetal metabolic healt...
