Objective: Type 2 diabetes mellitus (T2DM) is a multifactorial disorder with various disturbances in biochemical processes such as antioxidant status and lipid peroxidation. The aim of present study was evaluation of the oxidative stress markers in saliva of T2DM patients. Materials and Methods: In this study, 80 (40 T2DM and 40 control) individuals were assessed. The salivary total antioxidan...

many studies indicate that oxidative stress is involved in the pathophysiology of neurodegenerative diseases. oxidative stress can induce neuronal damages, modulate intracellular signaling and ultimately leads to neuronal death by apoptosis or necrosis. to review antioxidants preventive effects on oxidative stress and neurodegenerative diseases we accumulated data from international medical jou...

oxidative stress arises when there is a marked imbalance between the production and removal of reactive oxygen species that may lead to several diseases. cadmium is an environmental and industrial pollutant that results in formation of free radicals. the aim of this study was to determine the oxidative stress status in cadmium exposure workers. this is a cross-sectional study of 36 people of ca...

Background Diabetes mellitus type 2 (DM2) is associated with increased oxidative stress and oxidative damage to DNA. An appropriate intake of antioxidants via the diet can improve this disturbed oxidative status [1]. Apples are the most widely consumed fruits in Europe and represent a major source of antioxidants due to their high polyphenol content [2]. Apple pomace as a polyphenol-rich byprod...

conclusions the di was found to induce liver damage by oxidative stress mechanisms. silibinin reduced the oxidative stress by inducing antioxidant mechanisms, thereby showing protective effect against di induced liver damage. further studies with silibinin should be performed regarding di toxicity. materials and methods thirty two wistar albino rats were divided into four groups, as follows: 1)...

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...

In the efforts aimed at improving the quality of in-vitro-matured human oocytes, the dynamic balance and roles of pro-/ antioxidants merit further consideration. In-vitro maturation (IVM) is emerging as a popular technology at the forefront of fertility treatment and preservation. However, standard in-vitro culture conditions exert oxidative stress or an imbalance between oxidants and antioxida...

A series of studies in black and white women and men have suggested that serum g-glutamyltransferase (GGT) within its normal range might be an early marker of oxidative stress. If serum GGT is a marker of oxidative stress, it might have important implications both clinically and epidemiologically because measurement of serum GGT is easy, reliable, and not expensive. We examined the cross-sectio...

BACKGROUND Red wine contains a naturally rich source of antioxidants, which may protect the body from oxidative stress, a determinant of age-related disease. The current study set out to determine the in vivo effects of moderate red wine consumption on antioxidant status and oxidative stress in the circulation. METHODS 20 young (18-30 yrs) and 20 older (>or= 50 yrs) volunteers were recruited....
