Determination of diniconazole fungicide residues in grapes and zucchini by capillary gas chromatography

Pesticides are used on a large scale for agricultural purposes. The adverse effects of pesticides on both human health and the environment are a matter of public concern. Thus both the actual state and residue levels of pesticides in agricultural products should be extensively monitored. One of the new classes of pesticide is the triazole derivatives, which are very effective fungicides. In thi...

Effects of Spray Drying and Spray Chilling on Ibuprofen Dissolution

       The formulation of hydrophobic drugs for oral drug delivery is challenging due to poor solubility, poor dissolution and poor wetting of these drugs. Consequently, the aim of this study was to improve the dissolution of a model poorly water soluble drug, ibuprofen. Microparticles containing ibuprofen were produced by spray drying and spray chilling technology in the absence/presence of a ...

Methyl parathion comes inside.

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 ...

Sour Grapes

In most prokaryotes Asn-tRNA and Gln-tRNA are formed by amidation of aspartate and glutamate mischarged onto tRNA and tRNA, respectively. Coexistence in the organism of mischarged Asp-tRNA and Glu-tRNA and the homologous Asn-tRNA and Gln-tRNA does not, however, lead to erroneous incorporation of Asp and Glu into proteins, since EF-Tu discriminates the misacylated tRNAs from the correctly charge...
