Detection of organophosphorus compounds by covalently immobilized organophosphorus hydrolase.
As a consequence of organophosphorus (OP) toxins posing a threat to human life globally, organophosphorus hydrolase (OPH) has become the enzyme of choice to detoxify such compounds. Organophosphorus hydrolase was covalently immobilized onto a quartz substrate for utilization in paraoxon detection. The substrate was cleaned and modified prior to chemical attachment. Each modification step was mo...

متن کاملAntioxidants in organophosphorus compounds poisoning.
Oxidative stress has recently been implicated as a factor in the mortality and morbidity induced by organophosphorus (OP) compound poisoning. An overwhelming number of research papers are based on studying at the cellular and organ level. Such studies have concluded that antioxidants can be used as an adjunct compound in the treatment of both chronic as well as acute OP poisoning. Still, the ro...
متن کاملSide effects of organophosphorus compounds: delayed neurotoxicity.
Many organophosphorus compounds produce a chronic toxicity that has been classified as a dying-back process in which the long axons are particularly affected. Recent evidence indicates that an essential first step in the production of the lesion is the phosphorylation of a protein that is able to hydrolyse substrates such as phenyl phenylacetate. The esterase activity of the protein is inhibite...
متن کاملReaction of Trivalent Organophosphorus Compounds with Selenium
Over the years, evidence has been accumulating [1, 2] that selenium is an essential nutrient in animals, preventing various serious deficiency diseases. On the other hand, no such firm proof for the need of selenium in human nutrition has been established, although several instances of beneficial effects as a result of selenium supplementation of human diet have been reported [3-5]. Although va...
