supplementation has beneficial effects in immune system and can antioxidant enzymes activity increases during the exercise and protects the tissue against the oxidative stress. l-carnitine is a famous supplement and helps to protect against the oxidative stress during and after intense or prolonged exercise. the aim of this study was to investigate the effect of l-carnitine supplementation on t...

PURPOSE To investigate changes in the oxidant-antioxidant system in pterygium tissue. METHODS Tissue samples ablated from 40 patients during pterygium surgery constituted the study material, while normal nasal conjunctiva tissue samples from 20 patients matched for age group (who had undergone surgery for strabismus or extracapsular cataract surgery) were used as controls. The samples were ke...

Higher plants are sessile therefore are continuously exposed to different environmental stress factors, such as drought, salinity, heavy metals, nutritional disorders, radiation without any protection. Most of these stresses produce certain common effects on plants, like induced oxidative stress by overproduction of reactive oxygen species (ROS), besides their own specific effects (Rao, 2006). ...

Acne vulgaris is one of the most prevalent inflammatory skin conditions found in late childhood and adolescence. Despite various studies, the etiology or pathogenesis of acne is still not well understood and a single, primary cause has not been identified. In the past several decades, various studies have indicated that patients with acne are under increased cutaneous and systemic oxidative str...

INTRODUCTION Thyroid disorders are known to be a risk factor for cardiovascular diseases. Epicardial fat thickness (EFT) and oxidative stress are also believed to be major risk factors for cardiovascular events. The aim of this study was to evaluate the possible relationship between oxidative stress parameters and EFT in patients with subclinical hypothyroidism (SCH). MATERIAL AND METHODS A t...

Persistent inflammation and the generation of reactive oxygen and nitrogen species play pivotal roles in tissue injury during disease pathogenesis and as a reaction to toxicant exposures. The associated oxidative and nitrative stress promote diverse pathologic reactions including neurodegenerative disorders, atherosclerosis, chronic inflammation, cancer, and premature labor and stillbirth. Thes...

Objective Oxidative stress (OS) has been associated with numerous adverse pregnancy outcomes and fetal disturbances. Due to overproduction of reactive oxygen (ROS) and reactive nitrogen species (RNS) as well as inadequate induce of antioxidant protection newborns are particularly susceptible to oxidative injury. Furthermore, it has been shown that oxidative stress in adipose tissue may also imp...

Paraquat (PQ) is a commonly used herbicide that induces oxidative stress via reactive oxygen species (ROS) generation. This study aimed to investigate the effects of the antioxidant N-acetylcysteine (NAC) against PQ-induced oxidative stress in mice. Male Balb/C mice (24) were randomly divided into 4 groups and treated for 3 weeks: 1) control (saline), 2) NAC (0.5% in diet), 3) PQ (20 mg/kg, IP)...

Objective: Physical exercise has different effects on oxidative stress. Oxidative stress influences TLR4 and NFkB gene expression. The purpose of this study was to investigate the effect of aerobic training and vitamin D on gene expression of TLR4 and NFkB in lung tissue of obese rats exposed to oxygenated water. Materials and Methods: In an experimental study, 30 obese male wistar rats were r...
