The localization of glycoprotein synthesis and storage was studied during acrosome formation in guinea-pig using fine-structure autoradiography after (3H)-fucose incorporation. Three days after (3H)-fucose injection, labelling in spermatids was concentrated in the matrix of developing acrosomes, and it was evident that the fucosylation of acrosomal glycoproteins largely overshadowed the fucosyl...
On Saturday, April 26th, 1986 at 1:23 am, Block 4 of the nuclear power plant at Chernobyl exploded. The plant was located approximately 100 km north of the Ukrainian capital Kiev, near the border with Belarus. 180,000 kilograms of highly radioactive material is inside the reactor at the time an amount equal to 1,000 Hiroshima bombs. About 1019 Bq of radioactive material – consisting of at least...
The renewal of glycerol in the visual cells and pigment epithelium of the frog retina was studied by autoradiographic analysis of animals injected with [2-(3)H]glycerol. Assay of chloroform:methanol extracts showed that the labeled precursor was used mainly in lipid synthesis, although there was also some utilization in the formation of protein. Radioactive glycerol was initially concentrated i...
