Organophosphorus compounds, used as insecticides and agents of chemical warfare, are a major global cause of health problems. These irreversible inhibitors of cholinesterase produce three well-recognised clinical entities: the initial cholinergic phase, which is a medical emergency often requiring management in an intensive care unit; the intermediate syndrome, during which prolonged ventilator...

Direct, selective, rapid and simple determination of organophosphate pesticides has been achieved by integrating organophosphorus hydrolase with electrochemical and opitical transducers. Organophosphorus hydrolase catalyzes the hydrolysis of a wide range of organophosphate compounds, releasing an acid and an alcohol that can be detected directly. This article reviews development, characterizati...

Reaction of a cyclophosphinophosphonium cation with neat MeOTf represents a general and high-yield synthetic approach to dications enabling the isolation of the first derivatives of 2,4,5-triphosphino-1,3-diphosphonium as bis-triflate salts.

This letter is a response to the report by Sungur and Güven [1] on intensive care management of organophosphate insecticide poisoning, which was recently published in Critical Care. Insect damage costs the world loses approximately 6 billion pounds sterling every year. Use of pesticides has increased food production in parallel with population growth in many parts of the world. Many insect-born...

organophosphorus compounds are highly toxic chemicals that have application in production of warfare agents and agricultural pesticides. detoxification of areas that have been exposed to these types of materials is of vital importance and several approaches have been used for this purpose. biodegradation of organophosphates is one of these approaches that is in the center of attention due to it...

reaction of dialkyl acetylenedicarboxylates 1a-c andpyrrole derivatives 2a-e in the presence of triphenylphosphite (tpp) was investigated and the effect of the pyrrole substitution was established. diastereoselectivity is observed with pyrroles, 2a,b, yieldingphosphonate ester derivatives 3a-f and 4,and their relative configuration is determined by 1h/13c and 31p nmr and confirmed by single x-r...

Organophosphorus poisoning is common in rural Asia. Clinical features result from overactivity of acetylcholine receptors. Blackish discoloration of urine is not a feature of organophosphorus poisoning. Only one case of black colored urine following quinalphos poisoning has been reported in literature. We report two cases of organophosphorus poisoning from two different compounds, following whi...

In last few decades there is exponential increase in use of organophosphorus (OP) compounds as pesticides and insecticides leading to adverse effect on human population and live stock. There is a great need to develop portable analytical tools that are amenable for remediation and bioremediation process monitoring, where rapid analysis of large number of samples is essential. Determination of v...
