Modeling and optimizing Acid Orange 142 degradation in aqueous solution by non-thermal plasma.

The effects of the high voltage electrode material, initial pH of the solution, initial concentration of Fe, and time of plasma treatment on the efficiency of Acid Orange 142 (AO142) degradation were studied and evaluated. Furthermore, based on the Box-Behnken response surface methodology (BBD-RSM), a model between response (decolorization efficiency %) and influencing factors was proposed to estimate the interactive effects and optimize the process conditions. The proposed model was adequate with an R of 0.

Can zinc levels predict response to pegylated-interferon and ribavirin therapy in hepatitis C genotype 4 infected Egyptian patients?

Background And Aims: Zinc has been found to be low in chronic hepatitis patients. Its level was correlated with response to Interferon/ribavirin therapy in patients infected with hepatitis C genotype 1. In Egypt, inexpensive predictors to treatment response in Hepatitis C genotype 4 infected patients are desperately needed.
