BACKGROUND The aim of this study was to investigate the levels of oxidative stress including total oxidant status, total antioxidant status, and paraoxonase activity in patients with a diagnosis of acute appendicitis. METHODS Seventy-three patients who underwent surgery with a preoperative diagnosis of acute appendicitis (Group I) were included into the study. The control group (Group II) con...
INTRODUCTION Laparoscopic cholecystectomy is the gold standard for the treatment of gallstone disease; however, adverse hemodynamic changes induced by increased intraabdominal pressure due to pneumoperitoneum are known to occur. Herein, we investigated the effects of pneumoperitoneum on oxidative stress markers, including paraoxonase, arylesterase, total oxidant status, and total antioxidant st...
BACKGROUND Nut consumption is associated with a protective effect against coronary heart disease, partly due to its high antioxidant content. It is hypothesized that the inclusion of nuts in the diet will improve the antioxidant status of subjects with metabolic syndrome who may be vulnerable to impaired antioxidant status. AIM The effects of high cashew nut and high walnut diets on the antio...
The aim of this cohort study was to determine whether periodontitis and gingivitis are associated with impaired salivary antioxidant status and increased oxidative injury. One hundred and twenty-nine patients attending a routine dental check-up were recruited for the study. Periodontal disease status was characterized using the Community Periodontal Index of Treatment Needs (CPITN) system. Tota...
INTRODUCTION The ethiopathogenesis of tympanosclerosis has not been completely under- stood yet. Recent studies have shown that free oxygen radicals are important in the formation of tympanosclerosis. Melatonin and Vitamin C are known to be a powerful antioxidant, interacts directly with Reactive Oxygen Species and controls free radical-mediated tissue damage. OBJECTIVE To demonstrate the pos...
OBJECTIVES The purpose of this study was to determine the impact of changes in oxidative stress and antioxidant status in response to playing tennis in HOT (∼36°C and 35% relative humidity (RH)) and COOL (∼22°C and 70% RH) conditions. METHODS 10 male tennis players undertook two matches for an effective playing time (ie, ball in play) of 20 min, corresponding to ∼122 and ∼107 min of total pla...
Modern children aged from 12 to 17 years often have various health problems [1]. One of the main factors leading to aggravation is nutrition [2]. Primarily, nutrition can influence the parameters of antioxidant status of the child organism [3]. The aim of the study was to investigate the antioxidant status of urban and rural schoolchildren, and their actual nutrition. Antioxidant status was ana...
UNLABELLED It is possible that brucellosis may be related to increase free radical production and antioxidant depletion. Thus, in the present study we aimed to evaluate the oxidative status in patient with brucellosis and healthy controls. METHODS This study includes the patients with brucellosis diagnosed by clinical findings and positive agglutination titer. The paraoxonase, ceruloplasmin, ...
the present study examined the antioxidant defense of glutamine on plasma and liver antioxidant status in broilers under phs with respect to changes in the levels of lipid peroxidation marker malondialdehyde (mda), total antioxidant status (tas) and the activities of anti peroxidative enzymes [superoxide dismutase (sod) and glutathione dependent antioxidant enzymes glutathione peroxidase (gpx)]...
PURPOSE Oxidative stress and angiogenesis are important elements in the pathogenesis of inflammatory diseases and cancer. Vascular endothelial growth factor (VEGF) is one of the most potent angiogenic cytokines and is up-regulated by conditions associated with the generation of free radicals and reactive oxygen intermediates. In this study, we investigated the association between oxidative stre...
