Magnetic field as ecological factor has influence on all living beings. The aim of this study was to determine if extremely low frequency magnetic field (ELF-MF, 50 Hz, 0.5 mT) affects oxidative stress in the brain of gerbils submitted to 10-min global cerebral ischemia. After occlusion of both carotid arteries, 3-month-old gerbils were continuously exposed to ELF-MF for 7 days. Nitric oxide an...

BACKGROUND Oxidative stress might be associated with polycystic ovary syndrome (PCOS), but relatively small studies published to date do not permit reaching a definitive conclusion. We aimed at conducting a systematic review and meta-analysis of studies evaluating circulating markers of oxidative stress in patients with PCOS. METHODS We conducted a systematic review of studies reporting circula...

Introduction: Oxidative stress is an imbalance between the formation of Reactive oxygen species and protective antioxidant defense. It is known that oxidative stress increases the Acute renal failure. Measurement of oxidative stress parameters may be a simple tool for monitoring the progression of acute renal failure. Aim: The aim of this study was to evaluate oxidative stress in acute renal fa...

Telomere length has emerged as a marker of exposure to oxidative stress and aging. Race/ethnic differences in telomere length have been infrequently investigated. Leukocyte telomere length (LTL) was assessed 981 white, black and Hispanic men and women aged 45-84 years participating in the Multi-Ethnic Study of Atherosclerosis. Direct measurement and questionnaire were used to assess covariates....

abstract background: doxorubicin is used in treatment of many solid malignancies and lymphomas with poorly understood mechanism underlying tissue injury. rosemary leaves or extracts were found to contain high antioxidant activity almost equivalent to bha (butylated hydroxy anesole) and bht (butylated hydroxy toluene). thus, the possibility of aqueous rosemary leaves extract (re) to ameliorate d...

OBJECTIVE To investigate increased oxidative stress in saliva of smokers along with their serum. METHODS The case-control study was conducted from September to December 2008 in the Department of Biochemistry of the Medical School, Kirikkale University, Kirikkale, Turkey. A blood sample and saliva samples before and after smoking were collected from the smokers, while blood and saliva samples ...

Polycystic ovarian syndrome (PCOS) is a condition that increases the risk of metabolic diseases, such as insulin resistance, diabetes mellitus, and obesity, among others. Oxidative stress state elevated oxidants reduced antioxidants, which can be detrimental to body. Reduced glutathione (GSH) an important material with antioxidant properties. This study aimed investigate status oxidative in PCO...

The study was carried out to assess whether hot seasons affect the oxidative status of transition dairy cows. Twenty Holstein cows were utilized. Eleven of those cows gave birth in spring; the remaining nine cows gave birth in summer. Oxidative status was evaluated from 21 d before to 35 d after calving, determining oxidative markers in plasma [glutathione peroxidase activity, thiol groups, rea...
