Comparative Studies Of The Metal Activation Of The Cytoplasmic And Mitochondrial Forms Of Phosphoenolpyruvate Carboxykinase In Rabbit Liver (Gluconeogenesis)., Gertrude Hanke Jacoby

Theses and Dissertations

The cytoplasmic and mitochondrial isozymes of phosphoenolpyruvate carboxykinase (PEPCK) catalyze the reversible decarboxylation and phosphorylation of OAA to PEP with GTP or ITP serving as the phosphoryl donor. The forward reaction is an essential component of the gluconeogenic pathway. The purpose of this research was to compare the effects of metal activation on the forward (decarboxylating) and reverse (carboxylating) reactions of the PEPCK isozmes purified from rabbit liver.A purification procedure for rabbit cytoplasmic PEPCK was developed. The final enzyme preparation was homogeneous as established by SDS-PAGE. Pure cytoplasmic PEPCK and pure mitochondrial PEPCK from rabbit liver exhibit identical electrophoretic behavior …

Regulation Of The Solubility Of Zinc In Milk (Calcium-Phosphate, Co-Precipitation, Iron)., Lowell S. Nelson Jr.

Theses and Dissertations

Humans absorb zinc, iron and copper more readily from human milk than from bovine milk or infant formulae. Given that solubility is requisite to absorption, the solubilities of select components, including zinc, were examined in preparations of bovine and human milk and in model solutions based on the low-molecular-weight components of the two milks. Solubility was examined over a pH range similar to that found in the human digestive system. Factors which could alter zinc solubility were examined by changing the composition of the model solutions and by fortifying milks with various compounds.Each aliquot of the models or milks was …

Part I: The Intraluminal Chemistry Of Calcium, Magnesium And Zinc In Human And Bovine Milks. Part Ii: Complexed Metal Ion Binding To Poly(Acrylic Acid): A Simple Model For In Vivo Metal Ion Binding., Richard Warren Ames

Theses and Dissertations

Part I. The bioavailability of calcium, magnesium, and zinc is greater from human milk than bovine milk, even though individual concentration magnitudes are reversed. Reasons for this are investigated by studying the complexation and precipitation reactions of these minerals and the low molecular weight ligands present in both milks at pHs ranging from two to eight. These reactions control the solubility of these minerals and we assume that for a mineral to be bioavailable it must be in solution and arrive at the appropriate intestinal segment for absorption. Techniques used to study mineral solubilities are: computer modelling, synthetic models, and …

A Burkean Logological Analysis Of Doctrine And Covenants Section 88, Joann Farias

Theses and Dissertations

This thesis applies Kenneth Burke's method of logology as exemplified in The Rhetoric of Religion to analyze the Mormon text Doctrine and Covenants Section 88. This method of logology is based on the assumption that what is said about God in theology reveals a religion's use of language to influence human motives. The logological method uses six analogies to discover the motives implicit in religious terminologies. These six analogies are as follows: words-Word, Matter-Spirit, the Negative, the Titular, Time-Eternity, and the Formal.

This study revealed that the terminology contained in Doctrine and Covenants uses motives far diferent from the motives …

Precinct Government In Salt Lake County, Utah 1852-1904, Steven K. Madsen

Theses and Dissertations

This thesis traces the origin, development, and decline, from 1852 to 1904, of Salt Lake County's judicial precincts. A precinct functioned as the basic subdivision of county government. Its boundaries were generally coterminous with those of local communities. It was established to allow for a degree of local control by the people.
Chapter two reveals that precinct justices experienced over time a marked decline in socio-political prominence. This is largely due to legislative statutes that decreased their jurisdictional powers. Chapter three examines the evolution of precinct boundaries. It is demonstrated that geographic distribution of individuals played a major role in …

The In Vivo And In Vitro Effects Of Pn200-110, A Novel Calcium Channel Blocking Agent (Hypertension)., Steven B. Magill

Theses and Dissertations

PN200-110 is an analogue of the 1,4-dihydropyridine class of calcium antagonists, which have previously been shown to be efficacious in lowering blood pressure in essential hypertension. In our study, PN200-110 was found to be effective in lowering systolic blood pressures both acutely, in normotensive and spontaneously hypertensive rats, and chronically in the hypertensive group. Heart rates were increased above pretreatment values following PN200-110 therapy, but these changes were statistically insignificant.The in vitro binding of (+)- methyl-('3)H PN200-110 to synaptosomal P(,2) membranes was found to be saturable, specific, reversible, temperature-dependent, and of high affinity to a single set of dihydropyridine receptor …

From Babylon To Zion: The Life Of William Mclachlan, A British Convert To The Mormon Church, Winifred Morse Mclachlan

Theses and Dissertations

William McLachlan, a Scotsman, was converted to the L. D. S. Church, in Braintree, Essex, England in 1859. The motivating factor in his life was his faith that Joseph Smith was a prophet to whom the Lord had restored the precepts of the original Christian church. His journals, his letters, his speeches, his life, were oriented toward one ultimate goal, to build the Kingdom of God and to gain a place for himself and his family in that kingdom.
This thesis is a biography of his life and examines his emigration to Zion, his settlement and adjustment to the frontier, …

Degradation Of Human Anaphylatoxin C3a By Rat Peritoneal Mast Cells: A Role For The Secretory Granule Enzyme Chymase And Heparin Proteoglycan, James Edmund Gervasoni Jr

Theses and Dissertations

Purified human C3a was iodinated (¹²⁵I-C3a) and used to study the interaction of labeled peptide with rat peritoneal mast cells (RMC). Cellular binding of ¹²⁵I-C3a occurred within 30 sec, followed by a rapid dissociation from the cell. Both the binding of ¹²⁵I-C3a and the rate of dissociation from the cell were temperature dependent. At 0°C, the binding of ¹²⁵I-C3a was increased and the rate of dissociation reduced, as compared to 37°C. Once ¹²⁵I-C3a was exposed to RMC, it lost the ability to rebind to a second batch of RMC. Analysis of the supernatants by …

Surface Coat Material Associated With The Developing Otic Vesicle, Allan R. Sinning

Theses and Dissertations

The purpose of the present study was to investigate the development of the otic placode/vesicle and the concurrent synthesis of an associated cell surface coat material (SCM) in the chick embryo. This was accomplished by means of precipitation of the glycoconjugate constituents of the SCM with cetylpyridinium chloride (CPC) and subsequent observation by scanning electron microscopy (SEM). Cryofixation and freeze-substitution were utilized to validate the results of CPC precipitation. In addition, specific sugar moieties present within the SCM were characterized, in part, using fluorescein isothiocyanate (FITC)-conjugated lectins.

Embryos utilized for SEM were incubated for 45-56 hours (stages 12-16), fixed in …

Brood Parasitism And Reproduction Of Canvasbacks And Redheads On The Delta Marsh, Rodney D. Sayler

Theses and Dissertations

I studied brood parasitism and breeding ecology of canvasbacks (Aythya valisineria) and redheads (A. americana) nesting on the Delta Marsh near Portage la Prairie, Manitoba, from 1977 to 1980. The dissertation focuses on 3 aspects of this investigation: 1) the role of prairie drought in influencing pochard reproductive performance, including a comprehensive review of hypotheses explaining evolution of brood parasitism in waterfowl (Anatidae), 2) behavioral ecology and evolution of host/parasite interactions, and 3) development of improved redhead aging techniques by using cluster analysis.

Redheads shifted egg distributions from eggs in redhead nests to eggs laid parasitically in canvasback nests during …
