Objective(s): Exposing to stress may be associated with increased production of reactive oxygen species (ROS). Therefore, high level of oxidative stress may eventually give rise to accumulation of oxidative damage and development of numerous neurodegenerative diseases. It has been presented that brain-derived neurotrophic factor (BDNF) supports neurons against various neurodegenerative conditio...

background and objective: a huge amount of investigational evidence support a role for oxidative stress as an intermediary of nerve cell dysfunction in parkinson’s disease (pd). polyphenols such as carvacrol have been indicated to prevent neuronal deterioration caused by increased oxidative load, thus, this study evaluated whether carvacrol administration would attenuate behavioral abnormalitie...

aim: we conducted this study to investigate the role of ramadan fasting on oxidative stress. materials and method: 23 people (16 male, 7 female) aged between 25 and 65 years were recruited in this study. 10cc venous blood samples were taken after 8- to 10- hours fasting on 2 different times: a week before ramadan and at the end of ramadan (day 27). portions of the serum samples were used immedi...

In living organisms production of reactive oxygen species (ROS) is counterbalanced by their elimination and/or prevention of formation which in concert can typically maintain a steady-state (stationary) ROS level. However, this balance may be disturbed and lead to elevated ROS levels called oxidative stress. To our best knowledge, there is no broadly acceptable system of classification of oxida...

introduction: the aim of the present study was to evaluate the effect of exercise training and l-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (mi). methods: four weeks after the surgically-induced mi, 40 male wistar rats were randomly assigned to the following 4 groups (n=10): mi-sedentary control (sed) mi-exercise (ex) mi-sed...

helicobacter pylori infection leads to different clinical and pathological outcomes in humans, including chronic gastritis and gastric neoplasia. it has been demonstrated that oxidative stress associated with inflammation plays an important role in gastric carcinogenesis. to evaluate the oxidative stress in h. pylori infection we studied the gastric juice levels of nitric oxide and the activiti...
