Ranging Patterns And Habitat Utilization Of Northern River Otters, Lontra Canadensis, In Missouri: Implications For The Conservation Of A Reintroduced Species, Deborah Dorothy Boege-Tobin
Ranging Patterns And Habitat Utilization Of Northern River Otters, Lontra Canadensis, In Missouri: Implications For The Conservation Of A Reintroduced Species, Deborah Dorothy Boege-Tobin
Dissertations
I studied the spacing patterns and habitat utilization by reintroduced northern river otters, Lontra canadensis, at two sites in Missouri because previous studies of otters indicate, plasticity of a species social structure will likely be due to the tactics employed in acquiring resources in any given area. Seven hypotheses were tested by employing radio-tracking, habitat assessment and geographic information system approaches: (1) home range (HR) and core area (CA) size differ by sex; (2) HR and CA size differ in breeding vs. non-breeding seasons; (3) percent range overlap differs by sex; (4) habitat utilization, as indicated by latrine use, …

The Role Of Viruses In Fe Recycling In The World's Oceans, Leo Poorvin
The Role Of Viruses In Fe Recycling In The World's Oceans, Leo Poorvin
Doctoral Dissertations
Viral lysis is responsible for a significant fraction of bacterioplankton mortality in marine systems. This work shows that viral lysis of both heterotrophic bacterial and autotrophic cyanobacterial plankton releases iron (Fe) at a greater rate than is released from unlysed cells. These studies also show that the Fe released is bound to organic ligands, these ligands are not siderophores, and that these ligands have Fe binding stability constants similar to organic ligands found in seawater. Further, these studies have shown Fe released via viral lysis to be highly bioavailable to a range of model marine plankton and may potentially satisfy …
Understanding Immune Response In Mycobacterium Ulcerans Infection, Sarojini Adusumilli
Understanding Immune Response In Mycobacterium Ulcerans Infection, Sarojini Adusumilli
Doctoral Dissertations
Buruli ulcer is a necrotizing skin infection and is the third most important mycobacterial disease in immune competent individuals after tuberculosis and leprosy in humid tropical countries. The causative agent Mycobacterium ulcerans is unlike other mycobacterial pathogens in that it appears to maintain an extracellular location during infection. Another unusual feature of the bacterium is that it is the only mycobacterium known to produce a dermo-necrotic polyketide toxin called mycolactone. A single Buruli ulcer, which can cover 15% of a person's skin surface, contains huge numbers of extracellular bacteria. The infection is characterized by massive necrosis at the site of …
Studies On The Role Of Specific Residues Of The Saccharomyces Α-Factor Pheromone Receptor (Ste2p) In The Inactive And Active State, Yong-Hun Lee
Doctoral Dissertations
G protein-coupled receptors (GPCRs) are a class of integral membrane receptor proteins that are characterized by seven-transmembrane (7TM) domains connected by intracellular and extracellular loops, an extracellular N-terminus, and an intracellular C-terminus. To date more than 1000 GPCRs have been identified, and these proteins recognize neurotransmitters, sensory molecules and chemotactic agents. These receptors are involved in the control of many aspects of metabolism and play important roles in diverse processes such as pain perception, growth and blood pressure regulation, and viral pathogenesis. Therefore, these proteins became important target for therapeutic agents and recent reports indicate that nearly 40% of drugs …

Analysis Of Vehicle Use Patterns During Military Field Exercises To Identify Potential Roads, Chunxia Wu
Analysis Of Vehicle Use Patterns During Military Field Exercises To Identify Potential Roads, Chunxia Wu
Doctoral Dissertations
Military training is an intensive land use and can cause negative environmental effects. Many studies conducted under Integrated Training Area Management (ITAM) for quantifying the impact resulted from the military training exercise found that off-road vehicular activities during training exercises cause the major impact to the training land. Vehicle land use patterns at a certain location affect the impact severity: concentrated and repeated traffic create more serious damage to the land compared to the dispersed offroad vehicle movements. Those areas heavily disturbed by off-road traffic may require a longer period of time or special treatments for the land to return …
High Resolution X-Ray And Neutron Crystallographic Studies Of Escherichia Coli Dihydrofolate Reductase, Brad C. Bennett
High Resolution X-Ray And Neutron Crystallographic Studies Of Escherichia Coli Dihydrofolate Reductase, Brad C. Bennett
Doctoral Dissertations
Dihydrofolate Reductases (DHFRs) have been identified in nearly every proteome and are essential for most biosynthetic pathways involving one-carbon transfer reactions due to their recycling of tetrahydrofolate (THF). They catalyze the NADPH-dependent reduction of dihydrofolate (DHF), producing THF. Inhibition of DHFR ultimately depletes cellular pools of THF; causing a reduced supply of thymine nucleotides for DNA synthesis, resulting in genomic instability and cell death. Therefore, DHFRs remain important drug targets in antimicrobial and chemotherapeutic treatments. Despite exhaustive investigation of E. coli chromosomal DHFR, controversy persists over the dynamics of regulatory loops (the Met20, the βF-βG, and the βG-βH) and the …

Ligand Binding Studies In R67 Dihydrofolate Reductase And The Evaluation Of The Anion-Quadrupole Interaction At A Quantum Mechanical Level, Michael Robert Jackson
Ligand Binding Studies In R67 Dihydrofolate Reductase And The Evaluation Of The Anion-Quadrupole Interaction At A Quantum Mechanical Level, Michael Robert Jackson
Doctoral Dissertations
Dihydrofolate reductases (DHFR) are important, ubiquitous enzymes catalyzing the hydride transfer from NADPH to dihydrofolate and producing the tetrahydrofolate intermediate that is essential for many metabolic processes, particularly for its role in DNA synthesis. R67 DHFR is a plasmid encoded enzyme that confers resistance to the antibiotic drug trimethoprim. This enzyme is active as a homotetramer. The active site pore possesses 222 symmetry as a result. This symmetry gives rise to a different mechanism by which it binds its ligands. There are potentially four symmetry related binding sites, but various studies have indicated only three possible combinations that include: two …
Limits Of Temperature Tolerance Of Leishmania Enriettii And Leishmania Hertigi In A Real-Time Pcr Assay, Christina Salinas
Limits Of Temperature Tolerance Of Leishmania Enriettii And Leishmania Hertigi In A Real-Time Pcr Assay, Christina Salinas
Theses & Dissertations
Protozoans of the genus Leishmania are intracellular parasites found across five continents. They cycle between a promastigote form inside the digestive tracts of blood-feeding female sand flies and an amastigote form within mammalian host macrophages. Temperature is an important factor that must be defeated in order for the parasites' survival and continuance. This paper studies the limits of temperature tolerance by Leishmania enriettii and Leishmania hertigi. It was hypothesized that a correlation would exist between the limits of temperature tolerance to body temperature of their host. I explored growth characteristics at 21,27,29, 33, 35, 37, and 39° C. It was …
The Bovine Coronavirus 2'-O-Methyltransferase Binds Cis-Acting Stem-Loop Iv In The 5-Prime Untranslated Region Of The Viral Genome, Tara Beth Tucker
The Bovine Coronavirus 2'-O-Methyltransferase Binds Cis-Acting Stem-Loop Iv In The 5-Prime Untranslated Region Of The Viral Genome, Tara Beth Tucker
Masters Theses
The positive-stranded coronavirus genome, at 32 kilobases in length, is the largest known viral RNA genome, and internal cis-signaling elements directing its replication have been described only within the last ten years. The bovine coronavirus genome encodes 26 proteins in the region between the 5’-terminal 210-nt untranslated region and the 3’-terminal 298-nt untranslated region. Here, genes for 5 of the 26 proteins were cloned into bacterial expression plasmids for the long-term goals of characterizing enzymatic and RNA binding properties. These genes encode enzymes postulated to interact directly with the cis-acting RNA elements and carry out RNA synthesis, namely, the …

Effect Of Chitosan And Water Soluble Chitosan Coatings On Quality Of Small Fruits, Jason Ki-Myung Noh
Masters Theses
Edible coating has been applied on the surface of fresh produce to extend shelf-life by suppressing respiration, transpiration, and microbial growth. The coatings, thus, can help decrease moisture and weight loss, and may offer a protective barrier against bacterial contamination and spoilage. Recent studies have indicated chitosan as an effective coating that extends shelf-life and improves a storability of fruits. The objective of this study was to demonstrate the effectiveness of natural biodegradable chitosan coatings in extending shelf-life and quality of fresh small fruits, such as blueberries and grapes. Fruits were dipped for 30 seconds in 1% chitosan in 1% …
Human Equivalent Dose Modeling For Omega-3 Fatty Acid Supplementation In C57bl/6j Mice, Laura Louise Jones
Human Equivalent Dose Modeling For Omega-3 Fatty Acid Supplementation In C57bl/6j Mice, Laura Louise Jones
Masters Theses
The rodent model is often used to study the impact of dietary n-3 fatty acids on a variety of biological endpoints, and the results of these studies have been used to explain anticipated effects of n-3 fatty acid intake in humans. However, supplemental levels of n-3 fatty acids that are commonly used in rodent studies do not represent reasonable human intake, by comparison. Currently there is no standard method for the addition of n-3 fatty acids to rodent diets. We tested a mathematical model for dosing supplemental levels of α-linolenic acid (ALA) and eicosapentaenoic acid (EPA) to rodent diets on …
The Subcellular Targeting And In Vivo Metal Binding Characteristics Of Agnt84 Using Transgenic Tobacco And By-2 Suspension Cell Cultures, Brook Kay Nelson
The Subcellular Targeting And In Vivo Metal Binding Characteristics Of Agnt84 Using Transgenic Tobacco And By-2 Suspension Cell Cultures, Brook Kay Nelson
Masters Theses
AgNt84 is a nodulin protein expressed in Alnus glutinosa, an actinorhizal tree that participates with the actinomycete Frankia in symbiotic nitrogen fixation. Expression of AgNt84 mRNA is exclusively found within Zone 2 of the nodules, which is the zone that contains cells in the process of being infected by Frankia. A truncated form of the protein was found to bind Zn2+, Ni2+, Co2+, Cu2+, Cd2+, and Hg2+ in vitro. AgNt84 was predicted to be targeted extracellularly based on the presence of an N-terminal signal sequence. The purpose …
Tennessee Hay Supply And Demand Response To Prices And Other Factors, Jon Edwin Travis
Tennessee Hay Supply And Demand Response To Prices And Other Factors, Jon Edwin Travis
Masters Theses
The hay industry in Tennessee closely resembles a perfectly competitive market. There are no substantial barriers to market entry and farmers can freely exit if they so choose. A large number of firms and consumers (livestock producers and equine operators) exist. Hay is a fairly homogeneous product; although hay varieties are not identical, in many livestock production situations they are close substitutes. Producers are price takers in the market.
Currently, more information is needed regarding Tennessee hay supply and price response. The objectives of this study were: 1) to determine the factors that influence Tennessee hay acreage and yield, 2) …

Reverse Genetics With Tilling In Phytophthora Sojae, Melinda Beth Tierney
Masters Theses
The reverse genetic method TILLING (Targeting Induced Local Lesions in Genomes) is being applied to the plant pathogen Phytophthora sojae. The objective is to recover gene-specific mutants carrying allelic series and/or knockout induced mutations.
A library of 3000 mutant individuals was generated using the chemical mutagens ethylmethanesulfonate (EMS) or ethylnitrosourea (ENU). Gene-specific induced mutations are detected by screening a mirror library of genomic DNA. PCR is used to amplify and fluorescently label 1kb portions of specific genes from the mutant library and the PCR products are then heated and cooled slowly to form hetero- and homoduplexes.
The PCR fragments …

The Tennessee Wildlife Resources Agency (TWRA) reintroduced elk (Cervus elaphus manitobensis) into the Cumberland Mountains, Tennessee over a 3-year period beginning in December 2000. We radio-collared 160 elk and monitored them by aerial telemetry from February 2001 to June 2003. Locations (n = 1450) were used in a geographic information system (GIS) to develop a core herd home range (789-ha sampling area) to assess elk seasonal forage use and availability. We monitored diet and resource availability from November 2003 to October 2004 by vegetation sampling and microhistological analysis of feces. Tall fescue (Festuca arundinacea; 35.1%) dominated …
Paper Substrates For Electronic Printing, Laura K. Wood
Paper Substrates For Electronic Printing, Laura K. Wood
Masters Theses
Printed Radio Frequency Identification (RFID) labels utilize conductive inks to provide the means for wireless flow of electronic signals. An RFID label is an identification label with an integrated circuit and antenna that transmits data via radio waves to a reader, which sends the data to a computer for processing. RFID labels allow manufacturers and retailers to accurately track their inventory more efficiently than previously possible with bar codes. However, etched metal RFID labels are too expensive for widespread implementation. The key to reducing the cost of RFID technology is replacing etched metal tags with tags printed with conducting ink. …

An Evaluation Of The Effects Of Small, Man-Made Impoundments On Stream Macroinvertebrate Communities And Water Quality In Eastern Tennessee, Larry Eugene Everett Jr.
Masters Theses
Semi-quantitative benthic macroinvertebrate samples were collected from riffles above and below four small impoundments in eastern Tennessee. Watershed and habitat surveys and a variety of field measurements were performed for each sample site and each sampling event when appropriate. Samples were collected quarterly (seasonally) during a one-year period. The goal of the study was twofold: (1) to determine whether or not differences in stream macroinvertebrate communities above and below impoundments existed and if so, (2) to attempt to evaluate the possible effects of the impoundments on the downstream benthic community and water quality.
One-hundred and fifty-four distinct macroinvertebrate taxa in …
Brassica Mulches And Meal Control Fungal Wheat Pathogens In Vitro And Take-All Disease In Soil, Thomas Samuel Breeden
Brassica Mulches And Meal Control Fungal Wheat Pathogens In Vitro And Take-All Disease In Soil, Thomas Samuel Breeden
Masters Theses
Soilborne pathogens have an economic impact on crops throughout the world. Many survive saprophytically and therefore are difficult to control. Soil fumigation and seed treatments are sometimes effective. However, they are economically impractical for many crops. Crop rotation/alternative crops are often a practical, economical, and successful means of controlling soilborne pathogens. Recent studies have revealed that Brassica spp. Inhibit a wide array of plant pathogens. Decomposing species of Brassica release glucosinolates, which are converted to isothiocyanates (ITC) by the enzyme myrosinase. The ITC compounds inhibit microorganisms. The present study had three objectives. The first was to evaluate the effect of …
Cloning And Characterization Of Three Alleles Of The Mouse Furloss (Frl) Gene, Heather Marie Dech
Cloning And Characterization Of Three Alleles Of The Mouse Furloss (Frl) Gene, Heather Marie Dech
Masters Theses
Single-gene mutations in the mouse serve as useful models for understanding the pathophysiology and molecular mechanisms of human diseases. Three dominant autosomal mutations affecting skin, hair and eye development in the mouse were recovered in mutagenesis experiments at the Oak Ridge National Laboratory. Previous work demonstrated that these mutations constitute an allelic series at the mouse Furloss (Frl) locus, and they were given the symbols Frla, Frlb and Frlc. The heterozygous phenotypes of all three mutants are similar; the mice appear normal at birth but gradually lose their hair until the hair follicles and sebaceous …
