[Effects of Thiomersal on Apoptosis and Autophagy of Leukemia Cell Lines].

Objective: To investigate the effects of different concentrations of thiomersal on apoptosis and autophagy regulation of human leukemia cell lines U937, CEM-C1 and BALL-1.

Methods: The inhibitory effect of thiomersal on the proliferation of U937, CEM-C1 and BALL-1 cells was detected by CCK-8 assay. Annexin V-FITC/PI double staining flow cytometry was used to detect the apoptosis rate.

Investigation on activated semi-coke desulfurization.

An activated semi-coke with industrial-scale size was prepared by high-pressure hydrothermal chemistry activation, HNO3 oxidation and calcination activation in proper order from Inner Mongolia Zhalainuoer semi-coke, which is rich in resource and cheap in sale. SO2 adsorption capacity on this activated semi-coke was assessed in the fixed bed in the temperature range of 60-170 degrees C, space velocity range of 500-1300 h(-1), SO2 concentration of 1000-3000 ppmv, and N2 as balance. The surface area, elemental and proximate analysis for both raw semi-coke and activated semi-cokes were measured.
