Oxidative stress has been associated with prostate cancer development and progression due to an increase of reactive oxygen species (ROS). However, the mechanisms whereby ROS and the antioxidant system participate in cancer progression remain unclear. In order to clarify the influence of oxidative stress in prostate cancer progression, we performed this study in two human prostate cancer cell l...

background: alzheimer’s disease (ad) is the most prevalent degenerative disorder of the brain among elderly individuals. many studies indicate that oxidative stress is an important pathogenic factor which involves oxidizing macromolecules such as dna, lipids, and proteins in ad. green tea is a rich source of antioxidant compounds that can remove radical oxygen species. the purpose of this study...

evidence acquisition literature searching for studies on female infertility and micronutrient intakes, published between january 1984 and november 2014, was performed using the pubmed and embase databases. the bibliographies of included studies were also searched for additional references. results about 100 articles were identified and after the elimination of irrelevant studies, 28 related stu...

Infertility is a global health problem and it is one of the most stressful conditions amongst married couples. Even though not lethal, it has been described as a radical life changing problem that carries with it significant psychological trauma. Infertility can be caused by various problems and sometimes it is not possible to establish a cause. Oxidative stress, which arises from an imbalance ...

OBJECTIVE The aim of this study is to evaluate the relationship between cataract development and serum lipids, glucose as well as antioxidants in a case-control study. METHODS Ninety patients with cataract and 90 age- and sex-matched healthy controls were investigated. Lipid profiles including triglyceride (Tg), total serum cholesterol (Chol) and cholesterol content in high-density lipoprotei...

Ageing is a dynamic and progressive process that is characterized by the occurrence of morphological, biochemical, functional and psychological changes in the organism. The aim of the present article is to provide updated concepts on oxidative stress, covering its importance in aging, as well as nutritional status and supplementation with antioxidants (substances that prevent or attenuate oxida...

Exercise has been shown to increase the production of reactive oxygen species to a point that can exceed antioxidant defenses to cause oxidative stress. Dietary intake of antioxidants, physical activity levels, various antioxidants and oxidative stress markers were examined in 20 exercise-trained "athletes" and 20 age- and sex-matched sedentary "controls." Plasma F2-isoprostanes, antioxidant en...
