The Role Of Thiamine Pyrophosphate In Regulating The Level Of Gamma-Aminobutyric Acid In The Central Nervous System, Bryant L. Adams
The Role Of Thiamine Pyrophosphate In Regulating The Level Of Gamma-Aminobutyric Acid In The Central Nervous System, Bryant L. Adams
Theses and Dissertations
The level of gamma-aminobutyric acid in the brains of white rats suffering from thiamine deficiency symptoms resulting from pyrithiamine or oxythiamine antagonism of thiamine or from thiamine deprivation was measured. The level of this amino acid was 17.5% lower in the brains of pyrithiamine-treated rats and 20.0% lower in the brains of thiamine-deprived rats than in the control rats. Daily injections of ten times the required amounts of vitamin B6 in rats treated with pyrithiamine or oxythiamine or by thiamine deprivation had no effect on the level of brain gamma-aminobutyric acid or on the psiological behavior of these rats. The …
Studies Of Rat Brain Thiamine Pyrophosphokinase, Lavell Rolfson Johnson
Studies Of Rat Brain Thiamine Pyrophosphokinase, Lavell Rolfson Johnson
Theses and Dissertations
The enzyme ATP:thiamine pyrophosphotransferase (thiamine pyrophosphokinaseJ was purified from acetone powders which were prepared from rat brains up to the chromatography on alumina C_γ step by a modified procedure that Mano (Y. Mano, J. Biochem., 42, 283 (1960)] developed for the purification of the rat liver thiamine pyrophosphokinase. The enzyme was purified 12 fold over that in the original extract of the acetone powder. A spectrophotometric assay for the brain thiamine pyrophosphokinase was developed utilizing brewer's yeast apotransketolase. The transketolase assay was able to detect less than 10^-11 moles of thiamine diphosphate, which was synthesized by the kinase, in the …
Water Chemistry Survey Of Boulder Basin, Lake Mead, P. R. Tramutt, Bureau Of Reclamation
Water Chemistry Survey Of Boulder Basin, Lake Mead, P. R. Tramutt, Bureau Of Reclamation
Publications (WR)
The survey results indicate that the impoundment of water behind Hoover Dam has not adversely affected the dissolved oxygen (DO) content and that water quality and DO content were uniform regardless of depth. The study made in April-May 1964 will provide water quality data of Lake Mead prior to releases from Lake Powell as a basis for evaluating Lake Powell's effect on water quality and limnology of Lake Mead. The performance of a DO analyzer was tested and found unsatisfactory at depths below 150 ft. Parameters tested by standard chemical analyses of water samples in the Denver Laboratory and by …
A Study Of 5-Fluorouracil: Its Effects And Mode Of Action In Drosophila Melanogaster, John B. Jenkins Jr.
A Study Of 5-Fluorouracil: Its Effects And Mode Of Action In Drosophila Melanogaster, John B. Jenkins Jr.
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Investigations involving the fluorinated pyrimidine, 5-fluorouracil, and its effects on viruses, bacteria, plants and mammals, have brought to light the following facts: FU inhibits the growth of bacteria, plants and mammalian cells and it decreases the ability of certain viruses to produce progeny. In other words, FU is an antimetabolite that inhibits growth and/or reproduction. Two mechanisms have emerged from these studies to define the mode of action of FU. The first mechanism involves the incorporation of the compound into the RNA of the organism thus altering the base sequence and creating a non functional or damaging nucleic acid. The …

Until the discovery of the major product of catecholamine n1etabolism, vanillylmandelic acid (VMA), by Annstrong in 1957 (1), biochemical studies of epinephrine and norepinephrine metabolism were dependent upon determination of the small quantities of these materials excreted unchanged in the urine. The methods designed to measure VMA have proved adequate to detect the gross abnormalities in metabolism usually associated with catecholamine-producing tumors (2-7), but more exact procedures are required for quantitative metabolic studies. Present spectrophotometric and electrophoretic methods are nonspecific in that they yield values for VMA that are higher than those obtained by chromatographic and isotope dilution techniques (5). …
