Oxidative stress is the result of the imbalance between reactive oxygen species (ROS) formation and enzymatic and nonenzymatic antioxidants. Biomarkers of oxidative stress are relevant in the evaluation of the disease status and of the health-enhancing effects of antioxidants. We aim to discuss the major methodological bias of methods used for the evaluation of oxidative stress in humans. There...
o bjective : increased levels of oxidative stress markers in periodontitis have been reported by recent studies. malondialdehyde (mda) and superoxide dismutase (sod) are both in- creased during oxidative stress. the aim of this study was to detect and measure the level of oxidative stress markers in peri-implant crevicular fluid (picf). their correlation with peri-implant clinical parameters wa...
Oxidative stress is emerging as a key factor underpinning life history and the expression of sexually selected traits. Resolving the role of oxidative stress in life history and sexual selection requires a pluralistic approach, which investigates how age affects the relationship between oxidative status (i.e., antioxidants and oxidative damage) and the multiple traits contributing to variation ...
derived oxidants commonly known as reactive oxygen species (ROS). ROS are capable of damaging cellular constituents generated in excess during the chronic, inflammatory, neurodegenerative disease process of leprosy. Severe oxidative stress has been reported in leprosy patients because of malnutrition and poor immunity. The decreased levels of SOD, glutathione and total antioxidant status in lep...
background : periodontal disease is a common oral disease, which oxidative stress plays an important role in its pathogenesis. the onset and progress of this disease is influenced by balance between oral biofilm and host response. regarding with the role of oxidative stress in the pathogenesis of periodontal disease and reduction of total antioxidant capacity in patients with periodontal diseas...
background: in the recent years, various studies have shown a link between the free radicals, antioxidants and periodontal diseases. the purpose of the present study was to evaluate the oxidative stress and the antioxidant status present in the gingival tissue and plasma of patients with chronic periodontitis and to evaluate the antioxidant property of taurine. materials and methods: periodonta...
introduction: toxic effects of pesticides are commonly associated with reactive oxygen species damage and pentoxifylline a phosphodiesterase inhibitor is a drug well known for antioxidant properties. the purpose of this study was to evaluate the oxidative damages following a subacute exposure to malathion, an organophosphorus insecticide and pentoxifylline's ability to counteract these eff...
background: the pathogenesis of ethanol in the liver and kidney is associated with an increase in free radicals and oxidative stress that leads to structural and functional abnormalities in these vital organs. methods: forty-eight male wistar rats were placed in eight groups and were treated as follows: control group (normal saline), group of ethanol (4 g/ kg), three doses of ardeh and honey co...
BACKGROUND Oxidative stress may accelerate ageing and increase the risk of chronic diseases, such as coronary heart disease (CHD). We assessed differences in oxidative stress, and iron and antioxidant status between elderly men living in Mediterranean southern Europe (Crete, Greece) and northern Europe (Zutphen, The Netherlands). DESIGN A cross-sectional study using data from two cohorts of t...
The imbalance in to oxidants and antioxidants leads to the condition called oxidative stress. The oxidative stress is considered as one of the etiopathological factors for development and /or exacerbation of psoriasis. Therefore we undertook this study to determine serum levels of oxidants (Malondialdehyde MDA, Nitric oxide NO) and antioxidants (Total Antioxidant Status TAS, Superoxide Dismutas...
