The Incorporation of Radioactive Sulfur into Thiamine by Saccharomyces Cerevisiae.
The biosynthesis of thiamine has been believed to be accomplished with the initial formation of the pyrimidine and thiazole moieties by independent routes, followed by a final step in which pyrimidine and thiazole are jointed together to form thiamine. Recently, Nose (1-3), Brown (4-7), and Leder (8, 9) separated the enzyme system from cell-free extracts of bakers' yeast which is capable of syn...
متن کاملStudies on Embryonic Induction using Radioactive Tracers
T H E nature of the agent which brings about induction during the early development of vertebrates has been extraordinarily difficult to determine. As yet we are not even certain whether there is a passage of a comparatively massive quantity of material from the organizer into the reacting competent tissue, as is probably most usually assumed, or whether the action is primarily located at the s...
متن کاملSTUDIES OF RADIOACTIVE COMPOUNDS: rx-sKtoDowsKrTE
Of the several species of uranium silicate minerals, sklodowskite has the most limited geographical distribution, the only recorded occurrence being that at Shinkolobwe, Katanga, Belgian Congo. It was first described by Schoep (1924a). The analogy with uranophane was recognized by Schoep (Ig24b) who subsequently (L927) described its. isomorphism with this mineral. Billiet (1936) obtained an rc-...
متن کاملStudies with a radioactive spinal anaesthetic.
The need for information about the fate of a spinal anaesthetic after its introduction into the spinal theca was early recognized (Miller, 1901), but many years elapsed before the problem was seriously studied by a number of workers, including Stout (1929), Kustner and Eissner (1930), Koster et al. (1936, 1938, 1939), Bullock and Macdonald (1938), and Shields (1942). In the main these workers a...
متن کاملMathematical Modelling in Radioactive Waste Leaching Studies
Transport phenomena involved in the leaching of a radioactive material from a composite matrix into surrounding water are investigated using three methods based on theoretical equations. These are: diffusion equation derived for a plane source model, rate equation for diffusion coupled with a first-order reaction and an empirical method employing a polynomial equation. The obtained results are ...
