Investigation of a Hazardous Metabolite, Ethylenethiourea, in Ethylene Bis-Dithiocarbamates, Fresh and Processed Tomatoes: Case of Mwea Division, Kirinyaga District

Interaction of bis(ethylene)tin(bis(salicylidene)ethylenediamine) with DNA.

The fluorescence spectral characteristics and interaction of bis(ethylene)tin(bis(salicylidene)ethylenediamine) [Et2Sn(salen)] with DNA are described. The polarity of the solvent has a strong effect on the fluorescence characteristics of Et2Sn(salen). Et2Sn(salen) bound to DNA showed a marked decrease in the fluorescence intensity with a bathochromic shift of the excitation and emission peaks. ...

Relation of Polyphenol Oxidases to Fungitoxicity.

Stemphylium sarcinaeforme (Cav.) Wilt. (formerly Macrosporium sarcinaeforme Cav.) and Monilinia fructicola (Wint.) Honey (formerly Sclerotinia fructicola (Wint.) Rehm.) are two fungi which have been widely used as test organisms for screening fungicides in the laboratory. S. sarcinaeforme is resistant to the toxicity of phenolic and quinonoid compounds (herein referred to as phenols and quinone...

Permeation and toxicity of ethylene glycol and methanol in larvae of Anopheles gambiae.

In this study, we applied proton NMR to measure the permeation of two cryoprotective agents (CPAs), ethylene glycol (EG) and methanol, into 1st instar Anopheles larvae. Calibration with standard solutions of EG or methanol (0-10 mol l(-1)) confirmed the reliability of the NMR measurements for determining the concentration of these solutes. To assess permeation, larvae were immersed in 1.5 mol l...

synthesis of ethylene bis-stearamide for acrylonitrile-butadiene-styrene polymer

ethylene bis-stearamide is one of the important acrylonitrile-butadiene-styrene ()abs)( polymer additives, which is used as lubricant, slip agent and mold release agent. in this research, ethylene bis-stearamide for abs application was synthesized using stearic acid and ethylene diamine under reflux condition. refluxing prevented ethylenediamine from evaporation and thus the initial molar ratio...
