The effect of novel synthesized aminophosphonates on membrane potential and electrical conductance of internodal cells of Nitellopsis obtusa and hemolysis of erythrocytes (RBC) was studied. It was found that those the organophosphorous compounds, when present at 10-100 microM concentrations, caused depolarization and increased electrical conductance of alga membranes. They also influenced fluid...

A work in the article is really commendable. Nevertheless, as per my perspective some missing parts of the study are being highlighted here. The study showed that use of organophosphorous (OP) compound was the commonest method of poisoning (44.4%) followed by drugs and insecticides. It is not clear what kind of insecticides were used for the suicidal purposes as many insecticides themselves are...

The newest results in the chromatographic analysis of pesrticides present in foods and food products are collected and the results are critically evaluated. Examples for the employment of preconcentration and prepurification technologies, gas chromatography using ECD, NPD, MS and MS/MS detection methods, liquid chromatographic methodologies such as thin-layer chromatography, high performance li...

Fresh normal serum treated with immune complexes is chemotactic for polymorphonudear leukocytes (PMN's) from a variety of species (1, 2). The factor in treated serum causing specific directional migration of PMN's has been identified as a molecular complex consisting of the fifth (C'5), sixth (C~6), and probably seventh (CtT) components of complement (2, 3). The manner by which the chemotactic ...

In a Belgian pilot study honey bee wax combs from ten hives were analyzed on the presence of almost 300 organochlorine and organophosphorous compounds by LC-MS/MS and GC-MS/MS. Traces of 18 pesticides were found and not a single sample was free of residues. The number of residues found per sample ranged from 3 to 13, and the pesticides found could be categorized as (1) pesticides for solely api...

The biosensor devices were first researched by Clark and Lyons in 1962, aiming to measure the blood glucose level. Currently, there is a popularization of blood glucose meters and various technologies have been developed mainly for applications in medical diagnostics and environmental monitoring. However, there is a wide range of applications for biosensors not yet available. The immobilization...

Abstract Organic esters of phosphoric acid and other organophosphorous compounds are enzymatically hydrolyzed during wastewater treatment by microbial phosphoesterases, especially phosphomonoesterase (phosphatase). For physiological reasons, the enzyme is inhibited its main inorganic reaction product, ortho-phosphate. It known that oxyanions transition metals, resembling molecular topology orth...

In order to develop detector working in gas phase for organophophorous molecules, resonant microcantilevers surfaces were chemically modified with pristine and functionalized TiO 2 nanorods. By using a solvothermal synthesis method...
