[How can we improve symptomatic hypotension in hemodialysis patients: cold dialysis vs isothermic dialysis].

Background: Symptomatic hypotension is the most frequent acute complication affecting patients during chronic hemodialysis treatment sessions. Many reports have demonstrated that the use of cool dialysate has a protective effect on blood pressure during hemodialysis treatments. In the present study, we investigated whether preventing the hyperthermic response had favourable effects on hemodynamic stability during the hemodialysis procedure while affording good tolerance to patients.

Green chemistry--views and strategies.

Background And Goal: The object of Green Chemistry is the reduction of chemical pollutants flowing to the environment. The Chemistry and the Environment Division of EuCheMS has assumed Green Chemistry as one of its areas of interest, but one question to solve is where Green Chemistry should be placed within the context of Chemistry and the Environment. The concept of Green Chemistry, as primarily conceived by Paul Anastas and John Warner, is commonly presented through the Twelve Principles of Green Chemistry.

Deltamethrin: uses and environmental safety.

Deltamethrin is a photostable pyrethroid providing valuable insecticidal activity against a large number of pests. Since it has potential uses for crop, cattle, and human health protection, extensive research work was done to evaluate its safety. Protection against insect pests in agriculture requires safety not only for applicators, but also for honey bees, nontarget insects and other arthorpods, mammals and birds in the wild and terrestrial fauna.

Forced volatilization or sweep extraction of organochlorine pesticide from vegetable extracts.

Selective partition by vapor solvent sweeping, on borosilicate wool, of organochlorine pesticides from fruit and vegetable extracts in the present apparatus and with the present technique provides sufficient cleanup for subsequent electron capture detector analysis. Amounts of organochlorine pesticides from 0.02 to 0.
