DOI: 10.1002/jssc.202001081 The cover picture shows a new HPLC strategy for quantitative analysis of multiple components via single marker (QAMS) to determine nine nucleosides (cytidine, uridine, 2'‒deoxyuridine, inosine, guanosine, 2'‒deoxyguanosine, thymidine, adenosine and 2'‒deoxyadenosine) in Rhizoma Paridis the first time. results methodology validation showed that there was no significan...

The incorporation of tritiated thymidine into DNA molecules was studied by electr.:m microscopic autoradiography. To make autoradiogram in electron microscopic level, DNA was extracted from rat ascites hepatoma (AH 130) cells after in vitro incubation with tritiated thymidine. Extracted DNA samples were rotary shadowed with platinum palladium and covered with emulsion. Silver grains demonstrate...

The time course of phosphorylation of thymidine and the effects of various inhibitors on the phosphorylation of thymidine and on DNA synthesis in Ehrlich ascites car cinoma cells in vitro were studied with a double-isotope labeling method. Hydroxyurea, mitomycin C, cycloheximide, puromycin, 1-0-D-arabinofuranosylcytosine, 5-fluoroorotic aldehyde, and the thiosemicarbazones of 2-phthalimido alip...
