Welding is a process during which fumes, gases, electromagnetic radiation and noise are emitted as by-products. Metal oxide particles are particularly hazardous components of welding fumes. Welding has been found to be associated with respiratory symptoms and our objective in the present study was to study the effects of welding on pulmonary function and serum oxidant-antioxidant status. Fifty-...

BACKGROUND AND OBJECTIVE: Oxidative stress can be described as a state brought on by an unfavorable rise in the generation of reactive oxygen species (ROS), growth ROS production, or decline antioxidant defense. The study aimed to investigate impact non-surgical periodontal treatment clinical parameters and serum malondialdehyde MDA, total capacity TAOC, oxidant status TOS smokers non-smokers p...

Antioxidants provide protection against free radicals formed as a result of increased metabolism in living organisms and the damage these cause to cell. For this reason, determining antioxidant levels can help eco-physiologists field understanding physiological state animal at that moment conservation biology. In study, TAC, TOC OSI values 12 Long-legged Buzzards (Buteo rufinus), 7 Common buteo...

AIM Evidence that oxidative stress plays a role in the development of bronchopulmonary dysplasia (BPD). There is a close relationship between oxidative stress and inflammation. In this study, it is aimed to investigate influences of hydrocortisone used in the treatment of BPD on anti-oxidant system in preterm infants with BPD. PATIENTS AND METHODS The study enrolled 33 infants with severe BPD...

INTRODUCTION Obstructive sleep apnea (OSA) is one of the most prevalent sleep disorders. In the present study, we assessed the nitrite level, which is an indirect indicator of nitric oxide (NO), total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI), which may be associated with endotel dysfunction. We investigated the difference between the groups and the r...

BACKGROUND Various biomarkers and assays have been used for assessment of (anti)oxidant status in hemodialysis patients, including those intended for measurement of serum total (anti)oxidants, most often as a part of panel biomarkers. METHODS Serum (anti)oxidant status was measured in 32 chronically hemodialyzed patients and in 47 healthy persons, using two oxidations and three antioxidant as...

OBJECTIVE This study aimed to measure paraoxonase/arylesterase activities and to evaluate the total oxidant and antioxidant capacities in obese children and in children with metabolic syndrome (MetS). METHODS A total of 151 children of comparable ages (13.23±1.96 years, 13.45±1.85 years and 13.95±1.31 years) were enrolled in the study. Forty of these were children with MetS, 55 were obese and...

The present study evaluated and compared the oxidative stress status of dogs undergoing laparoscopic or open ovariectomy. Twelve healthy female dogs were divided into two groups according to the type of the surgical procedure, laparoscopic or open ovariectomy. Plasma total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) levels for the evaluation of oxidativ...

Feline coronavirus (FCoV) is a highly contagious virus that is ubiquitous in multicat environments and may induce oxidative stress. This virus commonly causes an asymptomatic infection, which can persist in certain individuals. Sporadically and unpredictably, FCoV infection leads to feline infectious peritonitis (FIP), a highly fatal systemic immune-mediated disease. There are no data in the ve...

Behcet's disease (BD) is a chronic systemic inflammatory disease. Inflammatory reactions trigger the oxidative stress and oxidants decrease the level of antioxidants. In the present study, we aimed to determine serum oxidative/antioxidative status in patients with BD. Serum antioxidative status was evaluated by measuring total antioxidant capacity (TAC), paraoxonase 1, arylesterase, sulfhydryl ...
