High Energy Chemistry;
Chemiluminecscence (CL) generated during the thermal degradation of sodium persulfate in the presence of terbium(III) sulfate was studied. The CL spectrum corresponds to emission from excited terbium ions. It was found that Tb(III) acts not only as a photon emitter but also a catalyst for the thermal degradation of sodium persulfate. A scheme of reactions resulting in the formation of excited-state Tb(III) was proposed.

    Geranylgeraniol (GGO) at 50 μM induces apoptosis in HL-60 cells. We examined the effects of Zn2+ ions on this process. Treatment of HL-60 cells with Zn2+ ions inhibited subsequent GGO-induced fragmentation of DNA. In a cell-free system that consisted of a specific substrate for caspase-3 and...
