Two series of column experiments were designed to investigate the mobility of trace metals during ISCO of TCE by MnO4 in the presence of MnOx and Fe oxyhydroxides. Results indicated that despite variable pH, concentrations of Mo, Pb, Cu, Cd and Ni are rapidly attenuated from the aqueous phase. In contrast, Zn concentrations were not significantly attenuated, except in the presence of Fe oxyhydr...

Etoposide is one of the most successful chemotherapeutic agents used for the treatment of human cancers. The drug kills cells by inhibiting the ability of topoisomerase II to ligate nucleic acids that it cleaves during the double-stranded DNA passage reaction. Etoposide is composed of a polycyclic ring system (rings A-D), a glycosidic moiety at the C4 position, and a pendent ring (E-ring) at th...
