Alternative Material Nest Boxes And Impacts On Nestling Physiology And Adult Behavior In The Eastern Bluebird (Sialia Sialis), Jamie E. Jackson

Honors Theses

In the mid-nineteenth century, Eastern Bluebird (Sialia sialis, a native cavity nesting species) populations experienced serious declines because of a decrease in natural cavities and the introduction of non-native, competitive cavity nesting species. The creation of nest box programs led to an increase in bluebird populations and these programs continue to be of importance. In this study, a recycled metal ammunition can was used as a nest box to determine if this was a viable resource for bluebirds. This work investigated the effects of this alternate material nest box on nestling physiology and adult behavior with special emphasis …

Activation Of Nf-Κb Transcription Factor During In Vitro Differentiation Of Mouse Embryonic Stem Cells, Natalya A. Ortolano

Honors Theses

Embryonic stem cells (ESCs) are a promising cell source for regenerative medicine. However, recent studies indicated that ESCs and ESC-derived cells (ESC-DCs) lack functional innate immunity against various pathogens and inflammatory cytokines. This presents a barrier to clinical application, as ESC-DCs would be placed in a wound site and exposed to pathogens and inflammatory cytokines. Using mouse ESCs (mESCs) as a model, we recently demonstrated that they are deficient in expressing type I interferons (IFN) and inflammatory cytokines. To determine the molecular basis for this finding, this study examined the activation state of nuclear factor-κB (NF-κB), a transcription factor that …

Tracking Plastid Gene Migration In Karenia Brevis, Kelly E. Scott

Honors Theses

Karenia brevis is a marine dinoflagellate responsible for the harmful algal blooms (also known as red tides) in the Gulf of Mexico. K. brevis expresses antisense (AS) RNAs, each of which has a complementary region to the messenger RNA (mRNA) of a variety of genes. In dinoflagellates, many plastid (and mitochondrial) genes have migrated to the nuclear genome. It is unknown whether chloroplast genes, such as photosystem – D2, have migrated in K. brevis. It is also unknown where the gene that expresses the AS RNA for photosystem D2 resides. The protein-coding gene and the AS RNA-expressing gene could …

Granulins As Inflammatory Mediators In Alzheimer Disease, Randi G. Reed

Honors Theses

Alzheimer disease (AD) is a neurodegenerative disorder characterized by severe memory deficit and cognitive decline among the elderly. This degeneration is caused by the aggregation and deposition of a protein called amyloid-β (Aβ) in the brain. Aggregation of Aβ causes neuroinflammation in addition to other toxic events. However, it is unclear whether inflammation from an external source, such as from a traumatic brain injury (TBI), could trigger Aβ aggregation. In this context, several pro-inflammatory mediators such as cytokines and chemokines have been suspects. It is now hypothesized that a group of proteins called granulins (Grns) are unique inflammatory mediators that …

Alcohol Consumption And Dietary Behavior Among College Greek Students, William B. Stevens

Drinking has increased in even higher rates among students involved in Greek fraternities and sororities. The implications that this rise in drinking has on dietary behaviors are an important concern. While several studies have focused on investigating reasons for drinking and negative consequences with regards to drinking, literature is limited that focuses on how alcohol consumption affects dietary habits and behavior.

Purpose: The aim of this study is to investigate the effects of alcohol consumption on the dietary behaviors of college Greek students.

Methods: …

A New Species Of Euphorbia Subgenus Chamaesyce Section Alectoroctonum (Euphorbiaceae) From Limestone Hills Of Wayne County, Mississippi, Andrew C. Fennell

Honors Theses

As part of a project to document the vascular flora of Wayne County, Mississippi, an unusual Euphorbia, which keys to the Euphorbia corollata complex, was encountered in mature hardwood forests in limestone regions. Unlike typical E. corollata and E. pubentissima, these individuals have long petioles (0.4–1.2 cm), oval to ovate leaves, short stature, small cyathia, small seeds, and a different phenology. In order to test species boundaries, morphological character differences were explored using principal component analysis (PCA), and additional characters were gathered from plastid (rpL16) and nuclear (ITS) DNA data of the unusual individuals as well …

The Effects Of Lotion Fatty Acids On Gram Negative Skin Flora: Implications For Membrane Remodeling And Pathogenicity, Adrianna Eder

Honors Theses

AIM: The purpose of this experiment was to determine whether or not Enterobacter aerogenes, Acinetobacter baumannii, and Klebsiella pneumoniae, which are three gram negative bacteria commonly found on the skin, utilize fatty acids in a manner that affects bacterial phenotype. Furthermore, an objective was to gain a deeper understanding of how the alteration of bacterial membranes, as a result of fatty acid uptake, affected the pathogenicity, membrane permeability, and resistance in gram negative bacteria. METHODS: The lipids were extracted using the method of Bligh and Dyer and analyzed using thin-layer chromatography (TLC). A series of tests were performed, including a …

The Uptake And Incorporation Of Exogenous Fatty Acids Confer Phenotypic Advantages To Acinetobacter Baumannii, Saba A. Munir

Honors Theses

AIM: Acinetobacter baumannii is a ubiquitous gram-negative bacterium found on a variety of surfaces that include skin, hair, and soil. Some gram-negative bacteria like A. baumannii have the ability to acquire and incorporate fatty acids into their phospholipid membranes. Known as ‘Iraqibacter,’ A. baumannii has emerged as a significant cause of nosocomial infections in the United States and abroad. This study was designed to determine whether structural alterations occur in A. baumannii upon exposure to a wide range of polyunsaturated fatty acids (PUFAs) as well as the significance of this phenomenon in terms of survival and resistance to stress. Thin …

Family Planning, Pregnancy, And Birth In Guatemala: Maya Women And Modern Healthcare, Kelsay Payton

Honors Theses

Within Maya populations in rural Guatemala, childbearing is considered a sacred and spiritual experience, in addition to a physical one. This country is home to some of the highest rates of maternal and infant mortality in Latin America, along with the largest disparities in health care, primarily between the indigenous Maya and ladino women (Schooley 2009). The use of biomedical reproductive services remains surprisingly low among the Maya, while it is continually rising in the ladino populations. To increase the overall reproductive health care in these indigenous communities, attention must be given to the understanding of Maya’s beliefs, therefore enabling …

Fueling Performance: Determining The Efficacy Of Low-Carbohydrate Diet Models For Athletic Populations, Chelsea Jackle

Honors Theses

Advocates of low-carbohydrate (LC) diets assert that these diets help lessen dependence on sugar while aiding in the metabolism of fat tissue. Additionally, it is believed that lipolysis helps dieters feel more energetic, lose weight, and improve physical performance. For these reasons, many athletes and active people are drawn to diets such as the Atkins Diet, the South Beach Diet, the Paleo Diet, and the Zone Diet. According to current evidence, excessive weight loss, ketosis, reduced glycogen availability, dehydration, and increased stress hormone levels make LC diets that severely limit carbohydrates disadvantageous for athletes. Although LC diets are widely followed, …

Investigation Of The Genetic Interactions Between Hippo Signaling Pathway And Drosophila C-Terminal Src Kinase (Dcsk), Hailey Jimin Kwon

Honors Theses

The focus of my research revolved around the intersection between the Hippo tumor suppressor pathway and the Src oncogenic pathway. Both pathways control tissue and organ size during development by regulating cell proliferation, cell death, cell migration, and cell adhesion. Aberrant functions in either pathway are often detected in human cancers and correlate with poor prognosis. The Drosophila C-terminal Src kinase (dCsk) is a genetic modifier of warts (wts), a tumor-suppressor gene in the Hippo pathway, and interacts with the Src oncogene. Reduction in dCsk expression and the consequent activation of Src are reported in hepatocellular and colorectal tumors. …

Coding Dna Into Music: An Alternate Way Of Analysis, Samuel Fesenmeier

Honors Theses

In the study, we are analyzing the human genome in order to determine patterns that may tell something about how DNA functions. Patterns require an explanation: it is highly improbable that they are random occurrence. These patterns may hint to something about how DNA functions. There are known patterns already discovered in DNA. For example, in the coding portion, three base pairs translate to a specific amino acid. In the non coding portion, however, specific patterns are not as simple.

We will search for patterns by applying a coding system that turns DNA into music. Music may serve as a …

Identification Of Bacterial Species Using Colony Pcr, Kaiti Walker

Honors Theses

My research consisted of two separate parts, both involving the PCR methods. In part one I was trying to identify bacteria isolated from a chicken coop. In part two I was trying to identify bacteria isolated from the bluff. In both parts, I used a technique called colony PCR. This concept uses a single colony of bacteria to complete the PCR reaction. One pipet tip from a single colony is selected from the plate and mixed into a tube containing ultrapure water. A small amount of this bacterial mixture is then added into the PCR reaction. In the first part …

Understanding A Possible Wonder Drug: A Radial Diffusion Assay For The Rapid Evaluation Of Antimicrobial Peptides, Dustin Walter

Honors Theses

Antimicrobial peptides (AMPs) have been a major research focus due to their potential to combat a variety of human pathogens. Our laboratory has identified several novel peptides that display significant antifungal activity. The effectiveness of these peptides in vitro has been promising; however, it has been shown that physiological concentrations of various salts along with other conditions are inhibitory to peptide activity. To further explore the inhibitory effects of these salts, a new assay was developed whereby we can observe the effects of various salts on the peptide killing activity. For our studies, we employed several clinical isolates of Candida …

Effects Of Soil Environment On Abundance, Diversity And Community Structure Of Ectomycorrhizal Fungi In Pinus Radiata, Sarah C. Steele

Honors Theses

Balanced and sustained nutrient cycles are critical to the success of the world's forest ecosystems. Research has shown ectomycorrhizal fungi (ECM) play a vital role in regulating these systems, as they store and mobilize cycled nutrients for the trees they colonize. Not all species of ECM allocate essential nutrients (nitrogen, phosphorous and carbon) to their host with the same efficiency. Studies have shown the soil environment is important for determining fungal distribution. To better understand the ECM fungal community of Pinus radiata, I explored the effects of soil characteristics (percent silt, percent clay, percent sand and soil water content) on …

Does This Have Gluten? Comparison Of Gluten-Free And Unrestricted Diets In Intestinal Bacterial Populations And Diversity, Bradshaw Hammond

Honors Theses

As different diets continue to grow in popularity within the United States, the effect of these diets upon bacteria in the intestines is only beginning to be understood. This study focused on the effect that a shift to a gluten-free diet has on the human gut microbiome. Three genetically close subjects were selected for observation over a six month time period. One subject observed a consistent gluten-free diet. A second subject started on an unrestrictive diet, switched to a gluten-free diet for three months, then returned to an unrestricted diet for an additional three months. The third subject left an …

Knowledge And Perceptions Of Vegetarian Diets Among College-Aged Students, Haley Marie Berich

Honors Theses

As health becomes a more primary focus for many Americans, people are turning to new diet choices. Vegetarian diets are available in a wide range of choices and have been found to provide many health benefits. However, adequate knowledge within the general public is lacking when it comes to vegetarian diets. The purpose of this study was to assess the knowledge and perceptions held by college-aged students at the University of Mississippi. A survey was developed and distributed in health and wellness classes that were offered to students of all majors. 187 completed surveys were returned, of which 7 (3.7%) …

The Effects Of Mouth Guards And Clenching On Strength And Power Measures Of A Countermovement Vertical Jump: A Pilot Study, Hannah M. Hudson

Honors Theses

Strength and power gains from either mouth guards or clenching have been reported in highly trained athletes from a number of studies utilizing different testing measures. However, there have not been statistically significant effects in a recreationally trained population; and there has not been a research design to combine multiple mouthpiece conditions (mouthpiece designed for performance, a traditional mouth guard, and no mouthpiece condition) with a clench and no clench sub-condition. Therefore, the purpose of this study was to evaluate potential ergogenic effects of mouth guards and clenching on strength and power measures of a countermovement vertical jump. Three recreationally …
