Research Public health scientists are increasingly discovering that the recent emergence or re-emergence of infectious diseases has an origin in environmental change (McMichael and Martens 2002; Morse 1995; Patz et al. 2000). These environmental changes encompass social processes such as urbanization and creation of transportation infrastructure, as well as eco-logic processes such as land and ...

This paper describes the distribution of parathion in blood and various other organs, according to the etiology of the intoxication. As a rule, concentration levels are small, especially in the blood and in the stomach are higher, particularly in cases of suicide. In studies carried out on some patients admitted to hospital with parathion poisoning, entero-hepatic recirculation could have been ...

Eleven large-plot trials were located across nine counties in eastern Arkansas to evaluate the efficacy of select insecticides on the rice stink bug. Lambda-cyhalothrin, zeta-cypermethrin, methyl parathion, and carbaryl achieved initial control. However, only lambda-cyhalothrin and zeta-cypermethrin maintained significantly lower counts of the rice stink bug at 14 days after treatment (DAT). La...

The effect of sub-lethal doses of Malathion and Methyl-Parathion was studied on the rat liver enzymes. Intravenous administration of both insecticides at weekly interval for four weeks resulted in increase in weight of various tissues, i.e., heart and spleen. Short term (24 hr) and long term (4 weeks) treatment with insecticides resulted in increased specific activities of liver enzymes, Acid p...

A comparative approach to the differences between systemic toxicity and developmental neurotoxicity of organophosphates is critical to determine the degree to which multiple mechanisms of toxicity carry across different members of this class of insecticides. We contrasted neuritic outgrowth and cholinergic synaptic development in neonatal rats given different organophosphates (chlorpyrifos, dia...

Over the past few years, concern for green chemistry and sustainable development has risen dramatically. Researchers make an effort to find solutions difficult challenges using chemical processes. In this study, we use oyster shells as a source prepare calcium oxide nanoparticles (CaO-NPs). Transmission electron microscopy (TEM) results showed CaO-NPs morphology, which was spherical in shape, 4...

Rapid methyl parathion detection was measured using a fabricated glassy carbon electrode (GCE) sensor designed the layer-by-layer (LBL) method. Multilayer assemblies were developed on by alternating depositions of anions and cations in which Dawson Type Polyoxometalate ?-K 6 [(P 2 W 18 O 62 ·H O)]·14H (?P POM) polyethyleneimine (PEI) stabilized silver nanoparticles (?PEI-AgNPs) acted as cations...
