The Lyme Disease Spirochete In Tick Species Collected From Warren County, Kentucky, Cheryl C. Onwu

Mahurin Honors College Capstone Experience/Thesis Projects

The overall goal of this present study was to determine the prevalence of the Lyme disease spirochete, Borrelia burgdorferi, in south central Kentucky. A survey of ticks collected from a single location in Warren County, Kentucky was conducted between the months of April and June, 2010. A total of 293 ticks were collected. Three species were identified: 264 (91.7 %) of the ticks were Amblyoma americanum, 18 (6.6%) were Dermacentor variabilis, and 1 (0.35%) was Ixodes scapularis. The ten remaining ticks were immature nymphs and could not be identified. After identifying the species and sex of …

What's That Hooting Sound? A Survey On Novel Sound Producing Mechanisms In Chameleons, Keyana Boka

Mahurin Honors College Capstone Experience/Thesis Projects

This research project seeks to study how chameleons generate low frequency vibrations, some audible and some not. The mechanism responsible for this 'hoot' is unknown. A modified tracheal appendage we termed “the resonator” has been hypothesized as the potential source of this sound. An anatomical survey was conducted on various chameleon species including, Chameleo melleri (Meller), Chamaeleo pardalis (Ambanja, Nosy Be, Panther, Sambava), Furcifer rhinoceratus, Chamaeleo dilepis (Flapneck), Chamaeleo rudis (Side-striped), Chamaeleo calyptratus (Veiled), Chamaeleo jacksonii (Jackson’s), Chamaeleo quadricornicus (4-horned), Chamaeleo quilensis (Flapneck), Chamaeleo senegalensis (Senegal), Chamaeleo jacksonii xantholophus (giant Jackson’s), and Rhampholean brevicaudatus (Pygmy). Each chameleon was dissected …

Determination Of Repetitive Jumping Intensity Relative To Measured Vo2max, Laura Igaune

Masters Theses & Specialist Projects

To regular exercise and a healthy diet, the American Heart Association (AHA) strongly recommends rope jumping, and according to previous studies, rope jumping is considered a very strenuous exercise. Therefore the purpose of this study was to determine the steady state metabolic cost of repetitive jumping on the Digi-Jump machine, and to determine if exercise on this device is more or less strenuous than similar exercise with a jump rope. We also evaluated relative intensity of this type of exercise, based on each person’s VO_2max as measured on a treadmill. Twenty – seven subjects completed two trials, one jumping …

Phenotypic Plasticity Of Oral Jaw Dentition In Archosargus Probatocephalus, Cynthia E. Worcester

Masters Theses & Specialist Projects

Phenotypic plasticity, the capacity of a single genotype to exhibit variable phenotypes in different environments, is common in many species. A sample of wild caught Archosargus probatocephalus, also known as sheepshead, from Florida was randomly divided into two treatment groups: one group was fed soft prey, Mercenaria sp. muscle tissue, and the other group was fed hard prey, Mercenaria sp. in the shell, for 365 days. It was hypothesized that the sheepshead fed hard prey would have a thicker tooth enamel layer containing more calcium, and therefore be stronger than the tooth enamel layer of those fed soft prey …

Influences Of A Cladophora Bloom On The Diets Of Amblema Plicata And Elliptio Dilatata In The Upper Green River, Kentucky, Jennifer Maria Yates

Masters Theses & Specialist Projects

Freshwater mussels are the most imperiled group of freshwater invertebrates globally. Recent research suggests a better understanding of mussel feeding ecology may facilitate and improve conservation efforts. The use of stable isotopes is becoming an increasingly common method to study aquatic food webs. Carbon (C) and nitrogen (N) are two of the most frequently employed elements in food web studies. Differences in natural abundance of ¹³C/¹²C can indicate which food sources are the basal sources of carbon incorporated into a consumer’s tissue, while the ratio of ¹⁵N /¹⁴N provides a method of assessing trophic …

Contour Extraction Of Drosophila Embryos Using Active Contours In Scale Space, Soujanya Siddavaram Ananta

Masters Theses & Specialist Projects

Contour extraction of Drosophila embryos is an important step to build a computational system for pattern matching of embryonic images which aids in the discovery of genes. Automatic contour extraction of embryos is challenging due to several image variations such as size, shape, orientation and neigh- boring embryos such as touching and non-touching embryos. In this thesis, we introduce a framework for contour extraction based on the connected components in the gaussian scale space of an embryonic image. The active contour model is applied on the images to refine embryo contours. Data cleaning methods are applied to smooth the jaggy …

My dad had early onset Alzheimer’s disease. I first knew something was wrong with him in 1995. He was 49 then, and I was just about to start the eighth grade. That’s the summer his company backed him into a corner and told him to quit or be fired. He had worked there 14 years. They said his behavior was changing, and they thought he was doing it on purpose. It took seven years to get an actual diagnosis. The doctors looked for everything. They just thought he was too young.

I’ve relied on materials found in my parents’ house …

"In Space" Or "As Space"?: A New Model, Charles H. Smith, Megan Derr

DLPS Faculty Publications

In this analysis natural systems are posed to subsystemize in a manner facilitating both structured information/energy sharing and an entropy maximization process projecting a three-dimensional, spatial, outcome. Numerical simulations were first carried out to determine whether n × n input-output matrices could, once entropymaximized, project a three-dimensional Euclidean metric. Only 4 × 4 matrices could; a small proportion passed the test. Larger proportions passed when grouped random patterns on and within two- and three-dimensional forms were tested. Topographical patterns within 31 stream basin systems in the state of Kentucky, USA, were then similarly investigated, anticipating that the spatial configuration of …

Endothelin-1 Induced Phosphorylation Of Erk1/2 In Bovine Corneal Endothelial Cells, Akhila Bethi

Masters Theses & Specialist Projects

The purpose of this study was to determine whether Endothelin-1 (ET-1) induced cellular responses in bovine corneal endothelial cells (BCECs) involves MAPK pathway by phosphorylating ERK1/2 protein kinase and to find out the phosphorylation patterns of ERK1/2 in confluent and sub-confluent cells. BCECs were isolated from bovine corneas and cultured in medium supplemented with 10% serum. Confluent (contact inhibited) and sub-confluent (actively growing cells) serum starved cells grown in T-75 flasks were treated with 10nM Endothelin-1. The control cells were left untreated. Total cellular protein was isolated using RIPA buffer and quantified according to the Peterson modification of the Lowry …

Next Generation Sequencing Reveals Gene Expression Patterns In The Zebrafish Inner Ear Following Growth Hormone Injection, Gopinath Rajadinakaran

Masters Theses & Specialist Projects

Loss of hair cells due to acoustic trauma results in the loss of hearing. In humans, unlike other vertebrates, the mechanism of hair cell regeneration is not possible. The molecular mechanisms that underlie this regeneration in nonmammalian vertebrates remain elusive. To understand the gene regulation during hair cell regeneration, our previous microarray study on zebrafish inner ears found that growth hormone (GH) was significantly upregulated after noise exposure. In this current study, we utilized Next Generation Sequencing (NGS) to examine the genes and pathways that are significantly regulated in the zebrafish inner ear following sound exposure and GH injection. Four …

This study examined population density and habitat use of a species of greater galago, genus Otolemur, around Mt. Kasigau, Kenya. Mt. Kasigau has a unique regional microclimate, a cloud forest, which provides many different flora and fauna a home. To examine population density, two different methods were used. The first method was using line transects and analyzing results using Distance 6.0. These surveys were conducted during both dry and wet season and results were compared after the study. The second method was to trap individuals and use mark-recapture to determine population density. When caught in a trap, individuals were …

Production And Degradation Of 4-Ethylphenol In Lactobacillus Sp. Pep8 Cultures And In Blended Swine Lagoon Enrichments, Clinton W. Copp

Masters Theses & Specialist Projects

4-Ethylphenol (4-EP) is a malodorant of swine waste and is derived from a component of lignin called p-coumaric acid (p-CA). The production of 4-EP from lignin in swine waste is untested. Additionally, the effect of Fe (III) on 4-EP levels is unknown. Four experiments were performed to determine if Lactobacillus sp. pep8 cultures, as well as enriched swine lagoon slurries, could liberate p-CA from lignin and convert p-CA to 4-EP. Furthermore, it was tested if the addition of Fe (III) influences the conversion of p- CA to 4-EP.

Experiment 1 tested Lactobacillus sp. pep8 cultures to determine if the addition …

Plant-Like Cryptochrome Does Not Promote Blue Light-Induced Resetting Of The Circadian Clock In Chlamydomonas Reinhardtii, Jonathan Howton

Masters Theses & Specialist Projects

The circadian clock is an endogenous timer that allows an organism to anticipate and properly prepare for the daily changes in the environment. This preparation occurs in the form of daily rhythms in metabolism, physiology, and behavior. These approximately 24-hour rhythms are reset upon environmental time cues such as the daily light/dark and temperature cycles. The unicellular green alga Chlamydomonas reinhardtii is a useful model organism for circadian clock research. It shows several well-characterized circadian rhythms of behavior, and the monitoring of its rhythm of phototaxis, or swimming towards light, has been automated. The receptors involved in entraining the clock …

Effect Of Lion Calls On African Elephants (Loxodonta Africana) In Addo Elephant National Park, South Africa, Margaret Rose Hook

Masters Theses & Specialist Projects

Perceived predation risk alters animals’ behavior. This shift in behavior often comes at the cost of attaining resources. Generally, African elephants (Loxodonta africana) experience little predation pressure; however, the risk of predation by lions (Panthera leo) increases other prey species are less abundant. In elephant herds, related females and their offspring travel together in family groups, led by the eldest female. Response to predation pressure was examined by playing lion calls to the population of 437 elephants at the Main Camp Section of Addo Elephant National Park (AENP) in South Africa. Unfamiliar lion calls from a …

The Effects Of Endothelin-1 On Cell Migration Of Corneal Endothelial Cells, Leah B. Frazier

Mahurin Honors College Capstone Experience/Thesis Projects

Wound healing occurs through the processes of cell proliferation (mitosis) and/or cell migration. The corneal endothelium in humans is known to be mostly non-proliferative. As a result, wounds in the corneal endothelium heal by migration. A 21-amino acid peptide called Endothelin-1 (ET-1) is studied in the Crawford research lab and is a known mitogen, i.e. increases cell proliferation. Data suggests that Endothelin-1 can stimulate cell proliferation in the corneal endothelium. This fact led to the first hypothesis that ET-1 stimulated wound closure in this cell layer. I explored this hypothesis using a bovine model of corneal endothelial cells isolated and …

Empowering The World Through Dentistry, Charles W. Vittitow

Mahurin Honors College Capstone Experience/Thesis Projects

Dentistry is a very specific trade that one develops after years of education and training. With this skill comes a great amount of power and opportunity to serve, and with great skill comes great responsibility. Many dentists have decided to answer the call of third world countries that lack proper health care and specifically dental care. They do this in a variety of ways from sending supplies, supporting a local clinic financially, or traveling to the country for a short-term trip where they provide dental care to as many patients as they are physically able to for 7 to 10 …
