A test method is described for the measurement, under standard conditions, of the amount of dichlorvos (00-dimethyl 2,2-dichlorovinyl phosphate) vapour emitted from insecticide slow-release units. Specimen results, obtained under these conditions, are given for the outputs of several types of unit during the initial 14-d period when output is greatest, with corresponding values for the concentr...

Sport and leisure horses in Morocco are treated with several anthelmintics, organophosphates (dichlorvos), benzimidazoles (mostly thiabendazole) or tetrahydropyrimidines (mostly pyrantel pamoate) against nematodes. We studied three horse stables in Rabat, one in Meknes and one in Bouznika. Two of the Rabat and Bouznika stables had introduced a large number of horses from countries (Argentina or...

Organophosphorus (OP) pesticides poison more than 3,000,000 people every year in the developing world, mostly through intentional self-poisoning. Advances in medical therapy for OP poisoning have lagged, and current treatment is not highly effective with mortality of up to 40% in even the most advanced Western medical facilities. Administration of a broadly active bacterial OP hydrolase to pati...

219 Abstract: Toxicity of neem extract in comparison with DDVP (Dichlorvos) was determined against the housefly (Musca domestica L). Neem leaf extract was applied at 5, 10, 20, 40 and 80 microgram/fly and DDVP was treated in 0.1, 0.2, 0.4, 0.8 and 1.6 microgram/fly doses. Lethal dose values were calculated with probit analysis and LD50 and LD90 values were found to be 8.4 and 169.8 ug/fly of ne...

The method of independent bounded differences (McDiarmid, 1989) gives largedeviation concentration bounds for multivariate functions in terms of the maximum effect that changing one coordinate of the input can have on the output. This method has been widely used in combinatorial applications, and in learning theory. In some recent applications to the theory of algorithmic stability (Kutin and N...

Ex vivo conversion of the anti-influenza drug oseltamivir to its active metabolite can be inhibited by the esterase inhibitor dichlorvos or by using commercial fluoride-oxalate tubes. Oseltamivir and its active metabolite remain intact in plasma samples during a proposed virus heat inactivation step: incubation at 60 degrees C for 45 min.

Reduced glutathione (GSH) and Glutathione S-transferase (GST) play important roles in the detoxification of several xenobiotic compounds, including pesticides. This study was carried out to access the effect of the organophosphate pesticide, dichlorvos on the activities of GSH, GST as well as lipid peroxidation of egg laying hens. Seven weeks old pullets weighing between 400-600 g divided into ...

The need for rapid and accurate detection systems is expanding and the utilization of cross-reactive sensor arrays to detect chemical warfare agents in conjunction with novel computational techniques may prove to be a potential solution to this challenge. We have investigated the detection, prediction, and classification of various organophosphate (OP) nerve agent simulants using sensor arrays ...

Recent results have shown that the generalization error of structured predictors decreases with both the number of examples and the size of each example, provided the data distribution has weak dependence and the predictor exhibits a smoothness property called collective stability. These results use an especially strong definition of collective stability that must hold uniformly over all inputs...
