The Interaction Of Promazine With Selected Macromolecules And A Membrane Utilizing Absorption And Emission Spectroscopy, Jess D. Keeler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The association of promazine-HCl with bovine serum albumin, ammonium detergent micelles, and hemoglobin-free-rabbit-erythrocyte membranes were measured using the changes in the absorption and the emission of the interactants plus the fluorescent probe 1-anilino-8-naphthalene sulfonate. The binding of a promazine to serum protein and membrane did not alter the emission of the drug. However, the binding did produce a measurable quenching of the membrane and protein fluorescence. The quenching reaction was pH sensitive for both the protein and the membrane. Promazine binding to serum protein produced a hyperchromic change in the drugs absorption spectrum which paralleled the quenching reaction. The binding …

A Simple Microradiometric Technique For The Rapid Measurement Of Monoamine Oxidase Activity In Rat Testicular Minced And Teased-Tubular Preparations, Ronald L. Urry

Biology

Two radiometric techniques are described for the measurement of monoamine oxidase activity in testicular tissue preparations. These techniques utilize 5-HT-2-¹⁴C (serotonin) as the substrate and measure its conversion into 5-HIAA-¹⁴C (hydroxy-indole acetic acid). The first technique described uses a substrate concentration of 0.9 µM (0.05 µCi) in an incubation volume of 3.1 ml and 120 mg of teased-tubules. Samples are incubated 1 hour. This assay was found suitable for use with teased-tubule preparations but not for preparations containing interstitual cells. An inhibitor was present in the interstitual cell preparations which at the low substrate concentrations used …

Growth Of The Rabbit Coccidium, Eimeria Magna, In Cell Cultures, Clarence A. Speer

Biology

The in vitro development of Eimeria magna was studied using various cell types and compared with corresponding development observed in the intestinal epithelial cells of rabbits at 3, 4 and 5 days after inoculation. Leighton tubes were inoculated with sporozoites and the cultures examined at various intervals after incubation with phase-contrast or interference-contrast microscopy. Mucosal scrapings from infected rabbits were also examined. Mature first- and second-generation schizonts were seen in Madin-Darby bovine kidney (MDBK) cells and epithelioid embryonic bovine liver cells, whereas no development beyond the sporozoite occurred in fibroblastic, embryonic, bovine liver cells, lamb trachea cells and aggregates of …

The Regulation Of Purine Biosynthesis In A Phosphoribosylpyrophosphate Aminotransferase-Deficient Mutant Of Salmonella Typhimurium, Wen-Cherng Tsai

Biology

The regulation of the alternate first enzyme of purine de novo synthesis (ribose-5'-phosphate aminotransferase) has been examined in pur-F 341, a purine-requiring mutant of Salmonella typhimurium deficient in the primary first enzyme (PP-ribose-P amidotransferase, EC 2.4.2.14). The ribose-5'- phosphate aminotransferase is feed-back inhibited by AMP, ADP, GDP and adenosine but not by ATP, GTP, GMP and free adenine. Pyrimidines (except CDP and UDP) and thiamine compounds show no significant inhibitory effect on ribose-5'-phosphate aminotransferase activity. The alternate enzyme seems to be also controlled at the gene-level by one or more intra-cellular purines (repression-derepression). The role of the aminotransferase in …

Homeotherm Productivity And Activity As A Function Of Microclimatological Variables, June K. Rushing

Biology

The purpose of this paper is to advocate the use of computer modeling as a tool in the study of homeotherm energetics. The relationships between measurable environmental variables and components of productivity were reviewed and discussed as a basis for data input in the models. Photoperiod, temperature, rainfall, and wind were suggested as measurable environmental parameters. The facets of productivity which can be predicted from these parameters are the timing, the energetic cost, and the energetic capacity for productivity.

Amino Acid And Protein Metabolism During Development Of The Alfalfa Weevil Hypera Postica (Gyllenhal), Darrel J. Gunderson

Biology

Amino acid and protein metabolism were studied during growth and development of the alfalfa weevil. The amino acids were separated and identified by two-dimensional thin layer chromatography on cellulose plates and quantitative determinations were made with a ninhydrin spectrophotometric method. The radioactive isotope glucose-U-C¹⁴ was used to determine amino acid requirements and their rates of synthesis. A total of 23 amino acids were identified in the fourth instar larvae. Of these, 21 were free amino acids and 17 were protein amino acids. Limited concentrations of methionine, Y-aminobutyric acid and tryptophan in the insect were directly correlated with their dietary …

Chemical Differences Between Nectar Of Onion And Competing Plant Species And Probable Effects On Attractiveness To Pollinators, Gordon D. Waller

Biology

Levels of potassium in nectar of onion, Allium cepa L., varied from 3600 to 13,000 parts per million, about ten times higher than that of nectar of competing flora tested. An open-pollinated amphidiploid derived from the interspecific cross, A. cepa x A. fistulosum L., was the only onion with nectar potassium level as low as that of competing flora, and it was more attractive to honey bees, Apis mellifera L., than was the common onion. Addition of potassium salts to sugar solutions at the rate of 1500, 3000, 4500, 6000, or 7500 parts per million potassium clearly reduced uptake of …

Kinetic studies showed that this L-asparaginase has a temperature optimum of 74 C, an activation energy of 11,400 calories, a pH optimum of 9.2 in sodium carbonate-bicarbonate buffer and Michaelis constant for asparagine of 3.7 x 10^-3 Mat 74 C and pH 9.2. …

Instructional Costs In The School Of Graduate Studies At Utah State University, Evan N. Stevenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Institutions of higher learning are presently experiencing budget constraints unparalleled in recent times. The desire to reduce unnecessary expenditures has extended from administrators to the faculty and even to students. However, one of the greatest difficulties seems to be in identifying those specific areas where economies might be effected.

Business and industry have experienced the critical need for effective methods of analyzing their costs in order to survive in a competitive economy. Cost accounting techniques have been developed and have assisted in pinpointing both strengths and weaknesses. However, the administrator in higher education has been reluctant to accept similar approaches …

Economic Development Of Thailand: An Analysis Of The Agricultural Sector, Thamnoon Soparatana

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study takes a look at government aid to agriculture in Thailand and attempts to analyze its effectiveness. Only two crops have been aided directly by the government, rice and rubber, though others have undoubtedly benefitted by improvements in the country's infrastructure. The regressions performed on some simple production functions indicate that rice yields have been improved through government programs. The program for rubber largely a subsidy for new plantings, ha as yet not had much impact on yields. This maybe due to the fact that the pay-off period is at least seven years. There is also some evidence that …

Educational Mathematical Games As An Aid To Learning With Seventh Grade Mathematics Students At Wahlquist Junior High, Lewis Riley Taylor

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

One of the trends in mathematics has been the introduction of educational games as learning devices . A student's attitude toward mathematics is recognized to be very high when games are used. Walter Cronkite, on CBS television, summed up the promise of educational gaming when he said, "By participating, by playing a game , an other - wise dull subject becomes fascinating and unforgettable to the student." (Nesbitt, 1971, p. 2) Bradfield states it in this manner:

Many teachers of mathematics are unbelievably boring in their approach to teaching. Consequently , many potentially strong students never develop any great liking …
