diazinon (dzn) is a synthetic organophosphorus (ops) insecticide widely used in agricultural and household applications. ops, particularly dzn, are highly lipid soluble liquids. intravenous lipid emulsion (ile) has been shown to reduce toxicity caused by some lipid soluble agents. we evaluated the antidote effect of ile on acute toxicity of dzn. twenty-four sprague-dawley female rats weighting ...

Organophosphorus compounds are ubiquitous in nature, and due to their innate chemical properties, serve a fundamental role in a number of important fields. Among the more prominent features that elevate their status as a unique and versatile class of compounds, include variable oxidation states, multivalency, asymmetry and metal-binding properties. Their presence in bioactive natural products, ...

Abstract Melatonin ( N -acetyl-5-methoxytriptamine) is a novel plant regulatory molecule currently under study. Its role as biostimulator and protector against abiotic biotic stressors, through the regulation of redox network change in expression many elements primary secondary metabolism, great interest. The possible protective effect melatonin mungbean seedlings, previously primed seed treate...

The fate and movement of the organophosphorus insecticide chlorpyrifos (CPY;CAS No.2921-88-2) and its metabolite chlorpyrifos-oxon (CPYO; CASNo.5598-15-2) determine exposures in terrestrial and aquatic environments.Detectable concentrations of the organophosphorus insecticide CPY in air, rain,snow and other environmental media have been measured in North America and other locations at considera...

This study investigated the effect of interleukin (IL)-10 on the expression of OX62, MHC-II and CD86 in bone marrow dendritic cells (DCs) in rats with organophosphorus poisoning. Sixty adult SD rats were randomly divided into normal control group (group A) (20 rats), 20 rats with organophosphorus pesticide poisoning (group B), 20 rats with organophosphorus poisoning, and IL-10 treated (group C)...

A highly sensitive fourth derivative spectrophotometric method is presented for the residue analysis of ethylenebis dithiocarbamate fungicide Maneb. The fungicide maneb forms a blue complex with sodium molybdate on heating which is studied spectrophotometrically. The method has been successfully applied to maneb determination in wheat grains and soft drinks with high recoveries. The analytical ...

Cover: Scanning electron micrograph of 7-day-old colony of powdery mildew (Blumeria graminis f.sp. tritici) on a wheat leaf. Insert shows a 2-day-old colony at higher magnification. Although the sensitivity of mildew populations towards certain fungicides has changed considerably over the years, implementation of resistance management strategies has helped to sustain an overall satisfactory deg...

Abstract Organophosphorus pesticides are currently extensively applied on the control of agricultural and forestry pests. The number poisonings deaths caused by organophosphorus increasing year year. Because complex matrix, numerous interfering substances, low poison content, pretreatment methods crucial for detection analysis such cases. As an adsorbent used pretreatment, magnetic nanoparticle...
