Characterization Of Microbial Communities In Karstic Sediments : A Study Of Cave Bacteria In Central Kentucky., Justine Kay Roback 1964- May 2005

Characterization Of Microbial Communities In Karstic Sediments : A Study Of Cave Bacteria In Central Kentucky., Justine Kay Roback 1964-

Electronic Theses and Dissertations

Few previous studies have compared microbial communities in subterranean and surface environments. Chemical analyses used to characterize the surface and cave microbial environments indicated limited exchange between surface and subsurface waters. Here, bacterial communities from four distinct cave sediments collected in central Kentucky and adjacent surface streams were compared using a combination of culture and molecular methods. Predictions were that: 1) Cave communities will have unique community structures when compared to those of nearby surface sediments, and 2) Genetic diversity of bacterial communities in cave sediments will be higher than those in nearby surface sediments. Since diversity and community structure …

Investigations Of N-Acetyltransferases In Human Hepatocytes And Rat Models., Jason Matthew Walraven May 2005

Investigations Of N-Acetyltransferases In Human Hepatocytes And Rat Models., Jason Matthew Walraven

Electronic Theses and Dissertations

This thesis begins by reviewing human N-acetyltransferases (Chapter I), then outlines experiments involving human hepatocytes and rat N-acetyltransferases (Chapters II-V). These experiments facilitated the development of a dissertation project designed to study N-acetyltransferase tissue-specific expression in inbred rat strains (Chapter VI). Real-time PCR experiments concluded that genetic and/or environmental factors influence N-acetyltransferase expression in cryopreserved human hepatocytes. Therefore, an animal model must be used to study N-acetyltransferase expression. Initial studies of recombinanatly expressed rat N-acetyltransferases (Nats) revealed a correlation between rat and human N-acetyltransferases in nucleotide and amino acide sequence, catalytic activity, substrate selectivity and thermostability, suggesting the rat is …

Role Of Inducible Nitric Oxide Synthase And P-Selectin In Platelet-Arteriolar Wall Adhesion And Associated Arteriolar Constriction During Lung Reperfusion., Alexander V. Ovechkin 1957- May 2005

Role Of Inducible Nitric Oxide Synthase And P-Selectin In Platelet-Arteriolar Wall Adhesion And Associated Arteriolar Constriction During Lung Reperfusion., Alexander V. Ovechkin 1957-

Electronic Theses and Dissertations

Reperfusion of the ischemic lung causes pulmonary arteriolar vasoconstriction and reduces alveolar perfusion. Lung ischemia-reperfusion (IR) injury leads to platelet and leukocyte activation which could contribute to decreased alveolar perfusion during reperfusion by platelet-arteriolar wall interactions (rolling and adhesion) and subsequent microvascular constriction. During the oxidative stress of ischemia and reperfusion, formation of reactive nitrogen species (RNS) may promote platelet adhesion to the vascular wall with subsequent formation of microthrombi and release of vasoactive substances. Platelets play an important role in causing reperfusion injury in the systemic vasculature through accumulation and release of mediators, but information is lacking about consequences …

The Alternatives To Detention Program : Assessment Of One Kentucky County's Efforts To Deinstitutionalize Status Offenders., Arthur Hayden May 2005

The Alternatives To Detention Program : Assessment Of One Kentucky County's Efforts To Deinstitutionalize Status Offenders., Arthur Hayden

Electronic Theses and Dissertations

Since the beginning of the juvenile justice movement in the United States over a century ago, considerable debate has persisted among policymakers and practitioners concerning the causes of juvenile offending and the appropriate responses to control it. Although the juvenile justice system was conceived and developed to provide individualized, benevolent treatment to young offenders, the system has gradually shifted to resemble a more punitive, adult criminal justice model. While presently the system includes characteristics of both the juvenile and adult justice models, future directions are uncertain. This is problematic for young offenders who need and deserve more solicitous care in …

General Ishii Shiro: His Legacy Is That Of Genius And Madman, Gregory Dean Byrd May 2005

General Ishii Shiro: His Legacy Is That Of Genius And Madman, Gregory Dean Byrd

Electronic Theses and Dissertations

This paper covers the development of the chemical weapons division founded by Ishii Shiro, and discusses the horrible experimentation that was done by the Japanese. These experiments have been a source of controversy. The Chinese feel the Japanese should acknowledge these as war crimes. When the Japanese left Manchuria, they left the world’s largest chemical waste dump behind, and even to this day the government refuses to admit the actions of Unit 731. The information on biological warfare that the Japanese discovered during the experimentation in China later was used as a negotiation tool with the United States to secure …

Effects Of Food Deprivation On Blood Lipid Concentration And Composition In Steller Sea Lions (Eumetopias Jubatus), Michelle Lea Berman Jan 2005

Effects Of Food Deprivation On Blood Lipid Concentration And Composition In Steller Sea Lions (Eumetopias Jubatus), Michelle Lea Berman

Electronic Theses and Dissertations

Steller sea lions, the largest Otariid, fast during their breeding season; during this time they refrain from ingesting food for a period of 12-43 days. Fasting, while undertaking an extremely energetically demanding activity (breeding and pupping), requires specific physiological adaptations. This study examined the physiological response to fasting of two age classes, juveniles and sub-adults, during the breeding and non-breeding seasons to determine how these animals utilize lipids and the pattern of fatty acid mobilization from lipid stores during fasting. Four juveniles and 5 sub-adults were fasted for one and two weeks, respectively, and blood samples were collected approximately every …

Novel Protein-Protein Interactions Regulate The Proteolytic Activity Of The Pro- Apoptotic Serine Protease, Omi/Htra2, Supriya Singh

Electronic Theses and Dissertations

Omi/HtrA2 is a mitochondrial serine protease with high homology to the bacterial HtrA proteins. Omi promotes caspase-dependent apoptosis by binding and degrading IAPs-inhibitor of apoptosis proteins. Omi can also induce caspase-independent apoptosis but the actual mechanism is still unknown. IAP's are not the only substrates cleaved by Omi. There are at least two more known substrates of Omi, the HAX-1 and the ped/pea-15 proteins. HS1-associated protein X-1 (HAX-1) is a mitochondrial protein, degraded by Omi after induction of caspase-dependent apoptosis. Ped/pea-15 is also an anti-apoptotic protein and is cleaved by Omi after induction of caspase-independent apoptosis. The proteolytic activity of …

The Effects Of Arsenic On Selenoprotein Biosythesis, Fanta Konate Jan 2005

The Effects Of Arsenic On Selenoprotein Biosythesis, Fanta Konate

Electronic Theses and Dissertations

Arsenic contamination of drinking water is a real public health problem in certain areas of South-East Asia where chronic exposure has been correlated to higher rates of lung, skin, bladder, kidney, and liver cancer. Although arsenic carcinogenicity is well established, the mechanism by which it induces cancer is poorly understood. Recent evidence suggests that oxidative stress could be a possible mechanism for the carcinogenic effects of arsenic. Selenium, in the form of selenocysteine, is necessary for the activity of several enzymes with a role in the defense against reactive oxygen species (ROS), primarily thioredoxin reductases (TrxR) and glutathione peroxidases (Gpx). …

Electronic Theses and Dissertations

Association of Mycobacterium avium subspecies paratuberculosis (MAP) with Crohn's disease (CD) and not with ulcerative colitis (UC), two forms of inflammatory bowel disease (IBD), has been vigorously debated in recent years. This theory has been strengthened by recent culture of MAP from breast milk, intestinal tissue and Blood from patients with active Crohn's disease. Culture of MAP from clinical samples remained challenging due to the fastidious nature of MAP including its lack of cell wall in infected patients. The advent of real time PCR has proven to be significant in infectious disease diagnostics. In this study, real time reverse transcriptase …

The Effects Of Ecotourism On Polar Bear Behavior, Gillian Eckhardt Jan 2005

The Effects Of Ecotourism On Polar Bear Behavior, Gillian Eckhardt

Electronic Theses and Dissertations

Polar bears spend the majority of their lives on the sea ice, where they gain access to seals and mates. In western Hudson Bay, the sea ice melts for three to four months in the summer, and polar bears there are forced onto land. These bears live on their fat reserves for the duration of the iceless period, until temperatures get colder in the fall and freeze up begins. The aggregation of polar bears near Churchill, Manitoba during the ice free period has led to a thriving tourist industry, with a large influx of tourists visiting Churchill in the fall …

A Theoretical Approach To Assessing Annual Energy Balance In Gray Whales (Eschrichtius Robustus), Nathalie Lucie Elizabeth Greenwald Jan 2005

A Theoretical Approach To Assessing Annual Energy Balance In Gray Whales (Eschrichtius Robustus), Nathalie Lucie Elizabeth Greenwald

Electronic Theses and Dissertations

While direct measurements of energetic demands are nearly impossible to collect on large cetaceans, comprehensive bioenergetic models can give insights on such parameters by combining physiological and ecological knowledge. This model was developed to estimate necessary food intake of gray whales, Eschrichtius robustus, of the Eastern North Pacific stock. Field Metabolic Rates (FMR) for gray whales were first estimated based on various assumptions (e.g. volumetric representation of gray whales, extent of their feeding season, and blubber depth distribution) using morphometric data, energetic costs, and food assimilation according to age and gender specific requirements. Food intake rates for gray whales of …

Receptor Mediated Oral Delivery Of Bioencapsulated Green Fluorescent Protein Expressed In Transgenic Chloroplasts, Arati Limaye

Electronic Theses and Dissertations

The skyrocketing costs of prescription medicine in developed countries and their lack of availability in developing countries are the most challenging problems of human health. Primary reasons for such high cost are fermentation-based production, expensive purification methods, the need for low temperature storage and transportation and the delivery through sterile injections. Most of these expenses could be minimized or eliminated when therapeutic proteins are expressed and orally delivered via plant cells. Chloroplasts have the machinery to fold complex and biologically active eukaryotic proteins in the soluble chloroplast stromal compartment. Protein expression through chloroplast transformation system offers a number of advantages …

Historical Responses Of Marine Turtles To Global Climate Change And Juvenile Loggerhead Recruitment In Florida, Joshua Reece Jan 2005

Historical Responses Of Marine Turtles To Global Climate Change And Juvenile Loggerhead Recruitment In Florida, Joshua Reece

Electronic Theses and Dissertations

Marine turtle conservation is most successful when it is based on sound data incorporating life history, historical population stability, and gene flow among populations. This research attempts to provide that information through two studies. In chapter I, I identify historical patterns of gene flow, population sizes, and contraction/expansion during major climatic shifts. In chapter II, I reveal a life history characteristic of loggerhead turtles previously undocumented. I identify a pattern of juvenile recruitment to foraging grounds proximal to their natal nesting beach. This pattern results in a predictable recruitment pattern from juvenile foraging ground aggregations to local rookeries. This research …

The Role Of Histidine-Rich Proteins In The Biomineralization Of Hemozoin, Lisa Pasierb Jan 2005

The Role Of Histidine-Rich Proteins In The Biomineralization Of Hemozoin, Lisa Pasierb

Electronic Theses and Dissertations

Hemozoin formation, the consequential end product of the proteolysis of hemoglobin by Plasmodium falciparum, is essentially a biomineralization process whereby toxic free heme is aggregated into an inert crystalline solid, also known as malaria pigment or ß-hematin. The histidine-rich protein II (HPR II), isolated from the digestive vacuole of the parasite, has been implicated in the mediation of this biomineral through the protein's ability to bind heme, aggregate the biomineral, and be effectively inhibited by known antimalarials, including chloroquine. The HRP II sequence, which is comprised of 76% of histidine and alanine residues, has a specific amino acid repeat motif …

Selenotrisulfide Derivative Of Alpha-Lipoic Acid: Evaluation In A Cell Culture Model For Potential Use As A Topical Antioxidant, Melenie Lee Alonis Jan 2005

Selenotrisulfide Derivative Of Alpha-Lipoic Acid: Evaluation In A Cell Culture Model For Potential Use As A Topical Antioxidant, Melenie Lee Alonis

Electronic Theses and Dissertations

Selenium is a required micronutrient in mammalian cells. It is incorporated in the form of selenocysteine into selenoenzymes such as glutathione peroxidase and thioredoxin reductase, and is absolutely required for activity. Thioredoxin reductase is necessary for reduction of oxidized thioredoxin and therefore plays a major role in maintaining the redox status of the cell. Glutathione peroxidase is responsible for reducing peroxides into their corresponding alcohols and water. Together, these selenoenzymes constitute a significant part of the cell's arsenal to defend itself against oxidative stress. Exogenous sources of oxidative stress, such as UV radiation, are capable of generating reactive oxygen species …

Session-Based Intrusion Detection System To Map Anomalous Network Traffic, Bruce Caulkins Jan 2005

Session-Based Intrusion Detection System To Map Anomalous Network Traffic, Bruce Caulkins

Electronic Theses and Dissertations

Computer crime is a large problem (CSI, 2004; Kabay, 2001a; Kabay, 2001b). Security managers have a variety of tools at their disposal -- firewalls, Intrusion Detection Systems (IDSs), encryption, authentication, and other hardware and software solutions to combat computer crime. Many IDS variants exist which allow security managers and engineers to identify attack network packets primarily through the use of signature detection; i.e., the IDS recognizes attack packets due to their well-known "fingerprints" or signatures as those packets cross the network's gateway threshold. On the other hand, anomaly-based ID systems determine what is normal traffic within a network and reports …
