The activity of cancer procoagulant after ATO exposure was determined by a specific three-stage chromogenic assay.RESULTS: ATO decreased the CP activity in a dose- and time-dependent manner in MCF-7 cells with no effect on cell proliferation at the same time. However, it affected the CP activity of WM-115 cells in a different way. Reduction in CP activity was followed by an increase after 48 h incubation. The cells viability results showed dose-and time-correlated response within high arsenic concentrations.CONCLUSIONS: Arsenic trioxide downregulates the CP expression in human breast cancer and melanoma cells.Peer reviewedFinal Published versio
Russia's Afghan problem: The Russian Federation and the Afghanistan problem since 2001. OSW Study 38/2011
Russia is facing a difficult choice regarding its further policy towards the Afghan problem. It seems that Moscow has no coherent or consistent strategy. It is likely that the Russian ruling elite, like expert circles, is divided on this issue. In practice, the Russian authorities now seem to be simultaneously implementing elements of various strategies, thus trying to leave themselves the widest possible room for manoeuvre
