A diet rich in fruits, vegetables and minimally refined cereals is associated with lower risk for chronic degenerative diseases. Since oxidative stress is common in chronic degenerative disease, it has been assumed that dietary antioxidants may explain this protective effect. Every dietary plant contains numerous types of antioxidants with different properties. Many of these antioxidants cooper...
Proliferation of ovarian theca-interstitial cells is modulated by antioxidants and oxidative stress.
BACKGROUND Maintenance of ovarian homeostasis requires precise regulation of proliferation of thecal- interstitial (T-I) cells. Recent evidence indicates that oxidative stress and antioxidants modulate proliferation of various tissues under both physiological and pathological conditions. This study evaluated the effects of oxidative stress and antioxidants on T-I proliferation. METHODS Rat T-...
A major cause of male infertility, which includes 50 causes of infertility, is oxidative stress. The aerobic respiration in the sperm cell is associated with the production of reactive oxygen species (ROS). Some reactions such as sperm capacitation and acrosome reactions require moderate levels of ROS. However, when the amount of ROS production surpasses the natural antioxidant defense of the ...
This study compared the antioxidant status and major lipophilic antioxidants in patients with ataxia-telangiectasia (AT) and Nijmegen breakage syndrome (NBS). Total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), and concentrations of coenzyme Q10 (CoQ10) and vitamins A and E were estimated in the plasma of 22 patients with AT, 12 children with NBS, and the h...
Within the male reproductive system, oxidative stress (OS) has been identified as prevailing etiology of infertility. The effects reactive oxygen species (ROS) on fertility depend dimensions, “modus operandi” ROS and oxido-reduction potential (ORP) tract. Hereupon, for an adequate response to OS, cells our body are endowed with a well-sophisticated system defense in order be protected. Various ...
Oxidative stress plays a crucial role in dementia pathogenesis; however, its impact on salivary secretion and salivary qualities is still unknown. This study included 80 patients with moderate dementia and 80 healthy age- and sex-matched individuals. Salivary flow, antioxidants (salivary peroxidase, catalase, superoxide dismutase, uric acid and total antioxidant capacity), and oxidative damage ...
