Many decades of research have produced a significant amount of data showing increased oxidative stress in asthma and indicating a potential role for oxidants in the pathogenesis of the disease, particularly during exacerbations. Putatively relevant pro-oxidative mechanisms have also been identified. Currently available asthma drugs are generally effective for the treatment of the disease, but t...

Water pollution by organic contaminants is one of the most severe issues confronting world today as a result rapid increase industrialization, urbanization, human population growth, and advances in agricultural technologies. Several attempts have been made to address global water utilizing conventional wastewater treatment However, methods several limitations such low efficiency, high operation...

The imbalance in to oxidants and antioxidants leads to the condition called oxidative stress. The oxidative stress is considered as one of the etiopathological factors for development and /or exacerbation of psoriasis. Therefore we undertook this study to determine serum levels of oxidants (Malondialdehyde MDA, Nitric oxide NO) and antioxidants (Total Antioxidant Status TAS, Superoxide Dismutas...

boiling of water for its purification has been recommended since 500 b. o. modern desinfecition methods involve specialized treatments for the purpose of destroying or inactivating pathogenic organisms . different factors .in flu - ensing the efficiency of desinfection are considered in this article physical and chemical methods of water desinfection are described briefly the use of chemical ox...

Oxidants are highly unstable molecules that attack every chemical substance they come into contact. Oxidants modify the macromolecules both structurally and functionally. Body has defense mechanisms against oxidants in the form of both enzymatic and non-enzymatic antioxidants. Reactive oxygen species (ROS) are a group of oxidants formed during oxygen metabolism. ROS appears to be involved in th...
