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...
BACKGROUND The aim of this study was to explore oxidative stress status, especially the enzyme myeloperoxidase in children with end-stage renal disease. Also, we investigated possible associations between the atherogenic index of plasma and these parameters. METHODS Lipid status parameters, oxidative stress status parameters, and myeloperoxidase concentration were measured in the sera of 20 c...
OBJECTIVE Oxidative stress has been shown to contribute to the pathogenesis of acute and chronic lung inflammatory diseases. This article aimed to evaluate the oxidant/antioxidant status of children with acute bronchiolitis through the measurement of plasma total antioxidant capacity, total oxidant status, and oxidative stress index. METHODS Children with acute bronchiolitis admitted to the p...
Presently, no clear-cut guidelines are available to suggest the more appropriate physical activity for patients with type 1 diabetes mellitus due to paucity of experimental data obtained under patients' usual life conditions. Accordingly, we explored the oxidative stress levels associated with a prolonged moderate intensity, but fatiguing, exercise performed under usual therapy in patients with...
The aim of the present study was to evaluate ischaemic reactive hyperaemia (IRH) in obstructive sleep apnoea (OSA) and its relationship with oxidative stress. We studied 69 consecutive patients referred to our Sleep Unit (Reina Sofia University Hospital, Cordoba, Spain). Patients with chronic diseases or those taking medication were excluded. IRH was assessed before and after polysomnography. M...
PURPOSE Increased lenticular oxidative stress and altered calcium/magnesium (Ca/Mg) homeostasis underlie cataractogenesis. We developed a liposomal formulation of magnesium taurate (MgT) and studied its effects on Ca/Mg homeostasis and lenticular oxidative and nitrosative stress in galactose-fed rats. METHODS The galactose-fed rats were topically treated with liposomal MgT (LMgT), liposomal t...
INTRODUCTION Previous studies have demonstrated that thymoquinone has protective effects against ischemia reperfusion injury to various organs like lungs, kidneys and liver in different experimental models. OBJECTIVE We aimed to determine whether thymoquinone has favorable effects on lung, renal, heart tissues and oxidative stress in abdominal aorta ischemia-reperfusion injury. METHODS Thir...
OBJECTIVE To analyze whether nasal continuous positive airway pressure (CPAP) reduces oxidative stress in patients with sleep apnea-hypopnea syndrome (SAHS). PATIENTS AND METHODS Thirty-six patients with SAHS requiring nasal CPAP treatment and 10 controls in whom SAHS was ruled out were enrolled. Oxidative stress was evaluated by measuring plasma malondialdehyde (MDA) concentrations to assess...
INTRODUCTION Periodontitis is a common problem affecting a significant population of the world. For the assessment of oxidative stress of an individual, total oxidation status (TOS) and total antioxidant capacity (TAOC) are the significant biomarkers. Hence, we planned the present study to assess malondialde-hyde (MDA), TOS, TAOC levels, and oxidative stress index (OSI) in generalized aggressiv...
Introduction & Objective: Obesity is independently associated with increased oxidative stress in men and women. Natural antioxidants showed substantial antioxidative and anti-inflammatory activities in vivo. The aim of this study was to examine the preventive effect of antioxidant supplements and/or restricted diet on the stress oxidative index (8-Iso-PGF2α) and total antioxidant capacity (T...
