A Comparative Investigation Of Mammalian Serine Transhydroxymethylases, Sanha Panichajakul

Theses and Dissertations

Serine transhydroxymethylase was purified one thousand-fold from bovine brain and one hundred and twenty-fold from bovine liver. Both enzymes were yellow due to the presence of the coenzyme pyridoxal 5'-phosphate. Polyacrylamide gel electrophoresis of the liver enzyme showed one major band containing 95% of the protein, while in the case of the brain enzyme two major bands of nearly equal intensity were observable. The specific activity of the crude liver enzyme was about sixty times higher than that of brain. The liver enzyme was also more heat stable than the brain enzyme. The purified enzymes exhibited L-allothreonine and L-threonine aldolase …

The Kinetics And Mechanism Of A Free Radical Decay In Aqueous Solution, Denzel Lee Fillmore

Theses and Dissertations

The decomposition of nitrosyl disulfonate ion was studied in strongly alkaline solution of 10-2 to 5 m sodium hydroxide. The decomposition was found to be first-order in both hydroxide and nitrosyl disulfonate ions. A multi-step mechanism involving sulfite ion, sulfite ion radical and nitrosyl monosulfonate ion radical as intermediates was proposed, with the initiating step being the SN2 replacement of a sulfite ion by a hydroxide ion. The rate constant for the initiating step ranged from 1.2 x 10-7 to 2.25 x 10-5 M-1s-1 for the solution concentration range of the study. The products of the decomposition were identified as …

Composition, Time, And Size Distributions Of Airborne Particulate Material In Utah Valley, Douglas R. Lawson

Theses and Dissertations

The Lundgren impactor is used to determine the variations in time and size distributions of particulate matter in Utah Valley. Charged particle X-ray fluorescence is employed in this study to determine elemental concentrations. Air samples are taken during two 24-hour periods in downtown Provo, 24 hours near U.S. Steel Corporation, Geneva Works, and 12 hours at Lindon Elementary School, and diurnal particulate variations are compared. The amounts of lead and bromine are four times greater on a weekday than on a Sunday in downtown Provo, suggesting the effect of the automobile on atmospheric particulate concentrations. Paraffin coated impaction surfaces are …

Development Of Proton-Induced X-Ray Emission Techniques With Application To Multielement Analyses Of Human Autopsy Tissues And Obsidian Artifacts, Kirk Kay Nielson

Theses and Dissertations

A method of trace element analysis using proton-induced X-ray emission (PIXE) techniques with energy dispersive X-ray detection methods is described. Data were processed using the computer program ANALEX. PIXE analysis methods were applied to the analysis of liver, spleen, aorta, kidney medulla, kidney cortex, abdominal fat, pancreas and hair from autopsies of Pima Indians. Tissues were freeze dried and low temperature ashed before analysis. Concentrations were tabulated for K, Ca, Ti, Mn, Fe, Co, Ni, Cu, Zn, Pb, Se, Br, Rb, Sr, Cd and Cs and examined for significant differences related to diabetes. Concentrations of Ca and Sr in aorta, …

Use Of Selected Macroinvertebrates As Indicators Of Sedimentation Effects On Huntington River, Utah, Michael Kenneth Reichert

Theses and Dissertations

Benthic macroinvertebrate communities of Huntington River, Emery County, Utah were studied to determine effects of sedimentation from construction of Electric Lake Dam, a state highway, and two bridges. Approximately 900 benthic samples were collected from riffle areas above, in, and below the construction zone from January, 1971 to December, 1973. Two settling basins below construction sites were effective in limiting scouring of downstream communities. Heavy silt deposition was limited to a 1-km stream reach. Number of indicators, density, and biomass were reduced in the construction zone during periods of sediment input. During periods of scouring, density and biomass were reduced; …

Dance In The Church Of Jesus Christ Of Latter-Day Saints 1830-1940, Karl E. Wesson

Theses and Dissertations

The purpose of this study was to compile a history of dance in The Church of Jesus Christ of Latter-day Saints from 1830 to 1940.
The following subproblems have been investigated:
1. What was the history of dance in The Church of Jesus Christ of Latter-day Saints?
2. What was the philosophy of dance in the LDS Church?
3. What were the dance forms, music, and attire in dance within the LDS church?
4. What was the contribution of the LDS Church towards the preservation of folk dances in America?

A Survey Of Parental Knowledge Of Asthma, Nancy Aldred O'Donnell

Theses and Dissertations

The purpose of this study was to investigate the level of parents' knowledge regarding asthma.

Twenty-five parents of children who have asthma were interviewed during their child's hospitalization for status asthmaticus. Adequate knowledge about environmental control and medication was noted in the majority of the subjects but over half were unable to explain the pathological changes which caused wheezeing. While most parents appear to have adequate knowledge of medications and environmental control on which to base their decisions about their child’s care there appears to be a need for more information regarding the pathophysiology.

A Comparison Of Acrosomal Proteinase Activity In The Male And Female Reproductive Tracts Of The Guinea Pig, Thomas Joseph Morris

Theses and Dissertations

The spermatozoon has been the subject of numerous investigations because of its remarkable specialization for locomotion and fertilization. Although the spermatozoon of the guinea pig is relatively large when compared with other mammalian spermatozoa, its small size has hidden many of the details of its structure from the light microscopist. It was not until the invention of the electron microscope that a thorough study of spermatozoon structure could be accomplished. The following anatomical description is based on the works of Fawcett and Hollenberg (1963), Fawcett (1965), and Fawcett (1970). The principle parts of the guinea pig spermatozoon are the head …

The Morphologic Changes In The Muscles Of Mastication Due To Direct Intramuscular Injection Of Lidocaine, Carbocaine, Procaine And Citanest, Kurt Elliot Friedman

Theses and Dissertations

One of the most commonly experienced symptoms in dentistry and one that is of major concern to the dentist is pain. Since pain is manifested when an environmental change occurs causing injury to responsive tissues, it is often spoken of as a protective mechanism.

Pain has been described by a variety of terms: sharp, burning, aching, cramping, dull and throbbing! (Monheim, 1969). Therefore, it is a difficult term to define. Monheim (1969) describes pain as an unpleasant sensation created by a noxious stimulus that is mediated along specific nerve pathways into the central nervous system, where it is interpreted as …
