Objective: To test the coalescence effect of two chemotherapy drugs at low effective dose(cisplatin and taxotere) combined with pomegranate juice on A549 cancer cells. Methods: Infrared spectroscopy method is a qualitative test that was performed to ensure the existence of the phytochemicals providing the antioxidant activity through the presence of the hydroxyl group(-OH). The viability of A549 cell line and normal MCs was tested using the neutral red uptake, Clonogenic survival, XTT and Cell migration assays. Results: Our results showed that this combination firstly led to a greater decrease in the viability of cells comparing to those treated with chemotherapy drugs alone, and secondly led to a significant reduction in cell migration. Conclusions: These data suggest a synergistic effect between the pomegranate and cisplatin which makes probably this combination a powerful option for treating lung adenocarcinoma and in parallel minimizing the systemic side effects.

Effect of Dye Structure on the Photodegradation Kinetic Using TiO<sub>2</sub>Nanoparticles

引用

Journal of Materials Science and Chemical Engineering 2017年第6期5卷 31-45页

作者： Hawraa Ayoub Mounir Kassir Mohammad Raad Houssein Bazzi akram hijazi Laboratory of Materials Catalysis Environment and Analytical Methods Faculty of Sciences I Lebanese University Beirut Lebanon Platform for Research and Analysis in Environmental Sciences (PRASE) Doctoral School of Science and Technology (EDST) Lebanese University Beirut Lebanon

In this study the effect of pH, adsorption behavior and the chemical struc-tures of two dyes (Methyl Orange and Bromothymol Blue) on the photo-degradation rate constant, was investigated. Adsorption isotherm shows that the adsorption amount of dyes on TiO2 surface is highly related to the pH of the solution and to the pKa of each dye. In acidic medium the adsorption percentage of Methyl Orange on TiO2 surface was 76% facing 5% for Bromothymol Blue. The kinetic study shows compatibility between the degradation rate constant and the adsorption percentage on the surface. In basic medium the adsorption percentage of Methyl orange and Bromothymol Blue is similar while the degradation rate of Methyl orange is two times faster than that of Bromothymol Blue which reveals the role of chemical structure in the photodegradation rate.
