An Experiment To Test For Rapid Evolution In An Introduced Ectomycorrhizal Symbiosis, Valerie Rewa

Honors Theses

The rapid evolution of introduced ectomycorrhizal-plant partnerships is an under- explored topic that may have immense impacts on ecosystems around the world. This experiment sought to identify and quantify this evolution and its impacts on both fungal colonization as well as plant growth. I used a laboratory experiment to analyze these factors in native and exotic genotypes of Suillus cothurnatus and Pinus species. Much of the data was not able to be collected, but that which was did not support the presence of rapid evolution in the mutualistic partnership. Pine species was seen to have a significant effect on plant …

Examining The Role Of The Drosophila Melanogaster Unc13 Protein In Open Field Activity Using Rnai, Islam Orabi

Honors Theses

Unc13 are proteins in the presynaptic neurons essential in controlling synaptic vesicle fusion and synaptic transmission. Recently, the reduction of Drosophila melanogaster Unc13 proteins (Dunc13), were found to result in a resistance to alcohol, highly reminiscent of tolerance formation. I investigated whether genetically reducing Dunc13 activity in Drosophila brain regions leads to different forms of behavioral plasticity using an open field activity paradigm. In my approach, a Dunc13 RNAi transgene was expressed in the Drosophila brain within the mushroom body, the ellipsoid body, and in all neurons. The activities of the flies were examined in the open field paradigm to …

The Biodiversity Of Deadwood-Associated Arthropods In The Southern Appalachian Mountains, Isabelle Ong

Honors Theses

A biodiversity hotspot is a location that has significantly elevated levels of biodiversity including many species found nowhere else, and which is also in danger of losing much of this diversity. By identifying biodiverse regions, conservation efforts can be targeted to those locations where they are likely to have the most beneficial impacts. We looked at deadwood associated arthropods within the Southern Appalachian Mountains to examine centers of biodiversity. Nine logs were sampled, three of which were located in Bankhead National Forest and six were located in the Great Smoky Mountains. Polymerase chain reaction was used to amplify the mitochondrial …

Being Female And Indigenous: Barriers To Reducing Bolivia's Maternal Mortality Rates Under Evo Morales, Channell Cole

Honors Theses

This thesis seeks to answer the question: What are the barriers to attempts to reduce Bolivia’s maternal mortality rate under Evo Morales? While Morales’ presidency began in 2006, the timeline is from 2004 to the present to account for changes due to his policy. Using activity theory and social capital theory, I argue that machismo and racism are two social factors that are barriers to efforts to reduce the maternal mortality rate. Machismo manifests itself uniquely in Bolivia, as I argue through a comparison to Paraguay. Machismo is also riddled with a history of anti-indigenous racism. I examine the Rockefeller …

Immunomodulatory Biomaterials For Cancer Immunotherapy, Larry Donnell Stokes Jr

Honors Theses

Cancer immunotherapy has become an effective treatment in the toolbox of oncologists. Immunotherapy offers a less toxic alternative to standard cancer treatments such as chemotherapy and can have prolonged curative effects to decrease cancer recurrence. Today, many drugs and biological agents have been developed that target the immune system and elicit an antitumor/cancer response. These agents are known collectively as cancer immunotherapies. While immunotherapies have radically improved treatment outcomes for many cancer patients, there are drawbacks to using these treatments. Immunotherapy treatments have poor clinical responses in patients with tumors that lack immunogenicity. Some of the treatments also pose a …

Repurposing Antiplatelet Drugs To Treat Platelet Mediated Metastasis, Brianna Chambers

Honors Theses

By applying cardiovascular drugs, which already have been proven effective and safe, to other diseases we can speed the drug discovery process, specifically to translate them into treatments for platelet-mediated metastasis. Each cardiovascular drug within antiplatelet drugs, targets one of the four following pathways: COX-1, thromboxane, P2Y12, or thrombin. There has been varying levels of success with treating adenocarcinomas like breast and colorectal cancer. Continued success in treatment could be the result of pharmacogenetics and further evaluation of dosage levels. By isolating mutation rates in various adenocarcinomas there is the possibility of a targeted treatment based on the mutated gene.

Incorporating Demographic Structure And Variable Interaction Types Into Community Assembly Models, Akhil Reddy Alasandagutti, Nayan Chawla

Honors Theses

Theoretical studies of ecological food webs have allowed ecologists to remove the constraints of specific location and timescales from their study of ecological communities; food webs are generally complex and thus empirical study is difficult. Further, this theoretical approach allows ecologists to compare ecological processes and outcomes across any possible food web structures. However, these simulated communities are only as useful as the model from which they were constructed. Modifying existing considerations in these models, and generating new ones, are the jobs of theoretical ecologists that seek to achieve the shared goal of a majority of simulations: representation of real …

Local adaptation occurs in populations when multiple subsets of the same population are exposed to different environmental conditions causing the beneficial evolution of each species in its respective environment (Delph 2018). PURPOSE: Using Pseudomonas fluorescens as a model organism, this project sought to understand how an individual’s relative fitness will be affected after undergoing local adaptation in three different environments. METHODOLOGY: To conduct this experiment, three identical strains of SBW25 and three identical strains of lacZ were grown up in three separate environments. Each environment contained an M9 minimal salt media supplemented with either dextrose, xylose, or a 50/50 mixture …

An Analysis Of The Effects Of Covid-19 On Students At The University Of Mississippi: Family, Careers, Mental Health, Hannah Newbold

Honors Theses

This study analyzes the effects of COVID-19 on students at the University of Mississippi. For students, COVID-19 changed the landscape of education, with classes and jobs going online. Students who graduated in May 2020 entered a poor job market and many ended up going to graduate school instead of finding a job. Access to medical and professional help was limited at the very beginning, with offices not taking patients or moving appointments to virtual only. This would require that each student needing help had to have access to quality internet service, which wasn’t always guaranteed, thus producing additional challenges.

These …

This thesis explores opportunity gaps, often related to achievement gaps, in education via the analysis of school board members’ responses regarding challenges that face future education, students, and the public school system. The perceptions of these school board members serve to address the sources, prevalence, and effects of inequities that exist in widening (perpetuating) this gap between students. After discussing and elaborating upon the perceived challenges and barriers located in the institution of education, school board member responses will again be used to present potential ways and opportunities through which the achievement gaps, relating to the success rates and testing …

Pain Management Approaches & Experiences: A Systematic Review Of Racial & Gender Differentials, Ann Hoover

Honors Theses

Health care disparities and the social determinants of health (SDOH) are beginning to integrate into public and political narratives of systemic inequities. Pain management is a wide-reaching domain of health care, with complexities arising from the subjectivity of pain and the implications for clinical care. In this thesis, I conduct a systematic literature review to explore the effects of race and gender on pain assessment, diagnosis, and treatment through a health equity lens. While much of health care disparity research emphasizes the effects on population health outcomes, these findings redirect attention to the tangible impacts of discriminatory encounters and experiences …

Gay Identity In The Gdr: The Homosexuelle Interessengemeinschaft Berlin Between Self-Expression And State Control, Susanna Cassisa

Honors Theses

This thesis examines the Homosexuelle Interessengemeinschaft Berlin (HIB), the

first gay liberation group in the German Democratic Republic (GDR). Specifically, it analyzes the demands and tactics of the HIB alongside London Gay Liberation Front activist Peter Tatchell at the tenth World Festival of Youth and Students (WFYS) in 1973. This study analyzes four primary sources: 1) the HIB’s banner from the WFYS, 2) the leaflet Tatchell distributed at the WFYS, 3) Tatchell’s placard from the WFYS, and 4) a 1978 letter from the HIB to the People’s Chamber arguing for a socialist information center geared toward a homosexual patronage.

The Role Of Cannabinoid Receptor 2 In Zebrafish Toxicities Following Developmental Exposure To Thc Or Cbd, Haley Watts

Honors Theses

As the laws concerning the regulation of Cannabis Sativa change across the globe, maternal use of cannabinoid-containing products during pregnancy is a greater concern than ever before. Little research has been conducted on the consequences of maternal use and developmental exposure to ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD. In this study, larval zebrafish (Danio rerio) were used to measure CBD and THC-mediated adverse outcomes including effects on larval length, eye area, and behavior in the cnr^+/+ and cnr2^-/- zebrafish strains where we discovered that cannabinoid exposure results in a decrease in each of these endpoints. Adult …

The Importance Of A Multidisciplinary Approach To Public Health: Addressing Food Insecurity Through A Biological And Sociological Lens, Chloe Grant

Honors Theses

Plants can sense the change of 1 ^oC in their growth environment and thus global climate change has a great impact on plant growth and development. The phenomenon that warm non-stress temperatures promote stem and petiole elongation, as well as leaf hyponastic growth, is collectively known as thermomorphogenesis. While it is known that the basic helix-loop-helix (bHLH) transcription factor PIF4 is highly inducible by temperature elevations and controls thermomorphogenesis in dicots (e.g., Arabidopsis thaliana), the molecular mechanism underlying thermomorphogenetic growth in monocots is not clear. In this study, I identify PIF4 orthologs in several economically important monocotyledonous species and …

Responses To Fine Particulate Matter (Pm2.5) Exposures In Two Wild-Type Zebrafish Strains, Connor Necaise

Honors Theses

Atmospheric fine particulate matter (PM_2.5) exposure poses great health risks across the globe, causing both acute and chronic illnesses in humans. Therefore, a more complete understanding of the mechanisms in which PM_2.5 induces these adverse health effects is urgently needed. Oxidative stress due to PAHs and other common components of PM_2.5 is a proposed mechanism for its adverse health effects. However, little is known about the actual mechanisms of PM_2.5 damage in humans. This study aimed to distinguish behavioral differences in two lines of zebrafish (AB & 5D) as a result of developmental exposure to …

Spectroscopic Analysis Of Potential Astromolecules Via Quantum Chemical Quartic Force Fields, Mason Gardner

Honors Theses

Astrochemistry has been substantially aided by computational techniques, particularly through the use of Quartic Force Field (QFF) analysis. Several methods have proven useful at correlating computed spectroscopic data with experimental observations. The F12-TZ QFF correlated well with experimental data for silicon oxide compounds, particularly those potentially involved in development from rocky bodies to planetary masses [27]. Compared to argon matrix experimental data, the vibrational frequencies for the molecules SiO2, SiO3, Si2O3, and Si2O4 become less accurate as the complexity of the molecules increases but should still be predictive of infrared characteristics of silicon oxides as they form clusters in space …

Analyzing The Effects Of E-Hook Peptides On Kinesin-1, Ashton Ward Murrah, Baylee Hope Howard

Honors Theses

Cancer is the second leading cause of death in the United States. Cancerous growth is a result of oncogenes, or mutated genes that increase the rate of cell division in an uncontrolled manner. Cell division, which consists of mitosis and cytokinesis phases, is dependent upon the active movement of kinesin motor proteins along microtubules to rearrange the cytoskeleton for equitable distribution of genetic material to daughter cells. As kinesins are vital to this process, if we could prevent kinesin from binding to the microtubules, cell division would cease.

The goal of this study is to develop a method to prevent …
