Seasonal Investigation Of Native Fishes And Their Habitats In Missouri River And Yellowstone River Backwaters, Shannon J. Fisher Jan 1999

Seasonal Investigation Of Native Fishes And Their Habitats In Missouri River And Yellowstone River Backwaters, Shannon J. Fisher

Electronic Theses and Dissertations

Interactions between the Missouri River and its floodplain have been severely degraded due to channelization and impoundment. Ecologists have assumed that backwaters are a critical habitat component for certain life stages of native fishes; however, documented relationships are limited. During this study, I monitored fishes, invertebrates, and habitats to help determine the importance of backwaters to native fishes of various life stages, and to assess the changes that occur in habitat characteristics and invertebrate densities during periods with differential connectivity. Seven assemblages of fishes, identified with catch-per-unit-effort data, had at least some relationship with the backwaters. The assemblages included two …


Biochemistry Of Hemolysin Toxin Activation By Fatty Acylation: Characterization Of An Internal Protein Acyltransferase, Michael S. Trent Dec 1998

Biochemistry Of Hemolysin Toxin Activation By Fatty Acylation: Characterization Of An Internal Protein Acyltransferase, Michael S. Trent

Electronic Theses and Dissertations

Hemolysin toxin produced and secreted by pathogenic Escherichia coli is one of a family of cytolytic, structurally homologous protein toxins known as RTX (repeats in toxin) toxins. RTX toxins are products of a gene cluster, CABD . The A gene product, nontoxic hemolysin (proHlyA) is made toxic by post-translational fatty acylation of two internal lysine residues. HlyC, C gene product, is essential for acylation, and acyl-acyl carrier protein (ACP) is the acyl donor. HlyB and HlyD are involved in secretion of the toxin. HlyC was thought to serve as an internal protein acyltransferase and remained uncharacterized until now. ProHlyA and …


The Impact Of Cocurricular Experience On Leadership Development, Deborah H. White Dec 1998

The Impact Of Cocurricular Experience On Leadership Development, Deborah H. White

Electronic Theses and Dissertations

This study investigated the impact of cocurricular activities on leadership development. College graduates recognized as community leaders were selected from three communities in Georgia, Kentucky, and Tennessee. Through survey and interview techniques, the leaders were asked to reflect on high school and college experiences that led to their development as leaders. The study included a focus on differences in experiences of male and female leaders. Developmental influences such as family, mentors, global experience, and the cocurricular activities engaged in during high school and college were explored. Title IX had no impact on increased opportunities for women in this group of …


Writing Center Practices In Tennessee Community Colleges, James E. Crawford Aug 1998

Writing Center Practices In Tennessee Community Colleges, James E. Crawford

Electronic Theses and Dissertations

The objective of this study was to develop a profile of writing centers in twelve community colleges governed by the Tennessee Board of Regents. This profile included how they were established, how they are funded and staffed, what services are provided and to whom, how training is provided for staff, and how technology is incorporated. More important than the profile itself, however, was an analysis of successful and unsuccessful practices, especially those related to governance, structure, and training of staff, as revealed through the perceptions and experiences of writing center directors. Because electronic technology has transformed the craft of writing, …


In Vitro Assessment Of The Toxicity Of Cocaine And Its Metabolites In The Human Umbilical Artery, Tessa L. Long Aug 1998

In Vitro Assessment Of The Toxicity Of Cocaine And Its Metabolites In The Human Umbilical Artery, Tessa L. Long

Electronic Theses and Dissertations

An in vitro model was used to assess the effect of cocaine and its metabolites on the umbilical artery. Objectives were to pharmacologically confirm the presence of adrenergic innervation using tyramine, evaluate the ability of cocaine, benzoylecgonine, norcocaine and cocaethylene to potentiate vasoconstriction by serotonin and norepinephrine, examine the ability of ketanserin to block the enhanced vasoconstriction produced by cocaine, and determine displacement of 3 H-ketanserin by serotonin, norepinephrine, tyramine and mianserin. The vasoconstrictive effect of tyramine (100 μM) was enhanced in the presence of cocaine by 257%. Vasoconstrictive effects of serotonin and norepinephrine were significantly enhanced by cocaine by …


Quantal Mechanisms Underlying Stimulation-Induced Augmentation And Potentiation, Hong Cheng May 1998

Quantal Mechanisms Underlying Stimulation-Induced Augmentation And Potentiation, Hong Cheng

Electronic Theses and Dissertations

Repetitive stimulation of motor nerves causes an increase in the number of packets of transmitter ("quanta") that can be released in the ensuing period. This represents a type of conditioning, in which synaptic transmission may be enhanced by prior activity. Despite many studies of this phenomenon, there have been no investigations of the quantal mechanisms underlying these events, due to the rapid changes in transmitter output and the short time periods involved. To examine this problem, a method was developed in which estimates of the quantal release parameters could be obtained over very brief periods (3 s). Conventional microelectrode techniques …


Tnf(Alpha)-Dependent And Tnf(Alpha)-Independent Activation Of Macrophage Effector Function, Annette R. Clemons-Miller May 1998

Tnf(Alpha)-Dependent And Tnf(Alpha)-Independent Activation Of Macrophage Effector Function, Annette R. Clemons-Miller

Electronic Theses and Dissertations

Tumor necrosis factor α (TNFα) is a pleiotropic cytokine that is predominantly produced by activated macrophages. The effects of TNFα are as diverse as the cells with which it interacts, e.g., stimulating fibroblast growth, exerting cytotoxic/cytostatic; activity against various human and murine cell lines, promoting inflammation through upregulation of endothelial adhesion molecules and IL-8 production. Yet TNFα is best known, and in fact was originally described, for its role in the bacterial-induced hemorrhagic necrosis of tumors and exacerbation of septic shock in which aberrant TNFα production leads to vascular collapse, cachexia, multiple organ failure, and ultimately death in as many …


The Influence Of A Human Repetitive Dna On Genome Stability, Eugenia L. Posey May 1998

The Influence Of A Human Repetitive Dna On Genome Stability, Eugenia L. Posey

Electronic Theses and Dissertations

A uniquely human interspersed repetitive DNA sequence family, the L2Hs, are highly polymorphic in human genomes. Several features of interspersed repeated DNA may contribute to the instability observed. Certain motifs (direct repeats, palindromes, and inverted repeats) comprising L2Hs elements may adopt unusual secondary structures such as cruciforms or hairpins. These motifs have been associated with features of genome instability in recombination, insertions and deletions. The L2Hs elements also are AT-rich (76%) compared to the bulk of human DNA (52%). That their dynamic nature (i.e. polymorphisms) may arise from recombination, insertions and deletions has led to the hypothesis that the L2Hs …
