Effect of high-dose insulin analog initiation therapy was evaluated on lipid peroxidation and oxidative stress markers in type 2 diabetes mellitus (T2DM). Twenty-four T2DM patients with HbA1c levels above 10% despite ongoing therapy with sulphonylurea and metformin were selected. Former treatment regimen was continued for the first day followed by substitution of sulphonylurea therapy with diff...

OBJECTIVES Increased levels of oxidative stress markers in periodontitis have been reported by recent studies. Malondialdehyde (MDA) and superoxide dismutase (SOD) are both increased 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 was in...

background: lipid peroxidation is a free radical-generating process which occurs on every membranous structure of the cell. free radicals are known to be involved in a number of human pathologies including atherosclerosis. the purpose of this cross-sectional study was to examine the association between pre-hypertension status and oxidative stress markers [total antioxidant capacity (tac) and ma...

Recent work has suggested correlation of oxidative stress with anxiety-like behavior. There also is evidence for anxiolytic effects of physical exercise. However, a direct role of oxidative stress in anxiety is not clear and a protective role of physical exercise in oxidative stress-mediated anxiety has never been addressed. In this study, we have utilized rats to test direct involvement of oxi...

Oxidative stress has been reported to play an important role in progression and prognostication in various kinds of cancers. However, the role and clinical significance of oxidative stress markers Keap1 and Nrf2 in oral squamous cell carcinoma (OSCC) has not been elucidated. This study aimed to investigate the correlation of oxidative stress markers Keap1 and Nrf2 expression and pathological fe...

BACKGROUND Since atherogenesis is related to oxidative stress, our objective was to study the association of oxidative stress markers with the vascular recurrence in non-cardioembolic stroke. METHODS Atherosclerotic and oxidative stress markers were evaluated on admission, in 477 patients suffering from a first non-cardioembolic stroke. Patients were followed at 6 and 12 months after inclusio...

BACKGROUND & AIMS Oxidative stress and low antioxidant levels are implicated in the aetiology of sarcoidosis, an inflammatory disease. Quercetin is a potent dietary antioxidant that also displays anti-inflammatory activities. Consequently, the aim is to examine the effect of quercetin supplementation on markers of oxidative stress and inflammation in sarcoidosis. METHODS A double-blind interv...

conclusions our results show that oxidative stress could play an important role in male infertility as well as in sperm motility and sperm morphology. patients and methods this case control study was conducted using 35 men with idiopathic infertility and 34 men with proven fertility. seminal plasma tac and mda were measured by ferric reducing ability of plasma (frap) and thiobarbituric acid (tb...

Oxidative stress (i.e., more oxidants than antioxidants) has been proposed as a proximate currency in life-history trade-offs, which if studied in an ecological setting allow a more realistic perspective on the origin and evolution of trade-offs. Therefore, the aim here was to investigate the impact of ecological and individual factors for variation in markers of oxidative stress using both exp...

OBJECTIVE Oxidative stress plays a major role in the development of atherosclerosis. However, the relationship between oxidative stress and complexity and intensity of coronary artery disease is less clear. The aim of this study is to assess the relationship between oxidative stress markers and the complexity and intensity of coronary artery disease in patients with acute coronary syndrome (ACS...
