Impact Of Urban Fine Particulate Matter Exposure On Cardiovascular Health, Shelby P. Briggs

Honors Theses

Air pollution, particularly exposure to fine particulate matter (PM2.5), poses a growing threat to cardiopulmonary health. PM2.5 consists of microscopic particles smaller than 2.5 microns in diameter and originates from industrial combustion, transportation, and urban dust. These particles are classified as xenobiotics and are capable of bypassing respiratory defenses to enter systemic circulation, where they cause oxidative stress, inflammation, and cardiovascular dysfunction. This study examines the effects of PM2.5 on cardiovascular function using a murine model. Male C57BL/6 mice were divided into control (saline), subchronic (10 µg), and chronic (100 µg) groups and were exposed weekly for 11 weeks via …

Effects Of Cytochalasin D On Motor Function In Drosophila, Airyel Noguera

Honors Theses

Actin proteins play an important role in microfilaments, one of the three components of the cytoskeleton of the cell. The actin protein is responsible for cellular functions such as with their role in neuromuscular junctions. The dynamics of these proteins can be further explored with manipulation of polymerization through the treatment of a biochemical drug, Cytochalasin D. This fungal toxin caps the ends of actin filaments, destabilizing them by inhibiting G- and F-actin monomers from binding. Treating Drosophila in their early embryonic stage with this drug after permeabilization can give insights on the importance of actin proteins at neuromuscular junctions …

Pilot/ Validation Of Protocol For An Alternative To Clinical, Morgan Sylvester

Honors Theses

All across the country, Clinical Microbiology laboratories are being consolidated into one location for an entire hospital network10. Though this helps reduce cost and staffing needs, it creates issues for the next generation of Medical Laboratory Scientists (MLS) trying to find clinical sites to complete clinical practicum rotations to complete the necessary certification processes. To combat this issue, it was proposed that MLS programs create alternative curriculums to offer in place of clinical rotations to reduce the amount of time students need in these rotations from three weeks to one week. This study investigated one alternative with the intent that …

Exploring The Relationship Between Diet And Mental Health, Emory Layne

Honors Theses

Dietary patterns in Western societies have shifted over the past century due to the rise of food manufacturing and technological advancements. Ultra-processed foods now account for approximately half of the daily energy intake in high-income countries. Similarly, the national mental health crisis emerged in the 21st century and worsened after the COVID-19 pandemic. The changes in diet have impacted the gut microbiome, which interacts with the brain through the bidirectional gut-brain axis. Research suggests the concept of the gut-brain axis is a principal indicator of diet’s impact on mental health. However, this area of research is still emerging and requires …

Knowledge Gaps And Personal Experiences: A Qualitative Examination Of Women's Menstrual Health And Birth Control Choices, Danielle M. Jackson

Honors Theses

Women all over the world face significant knowledge gaps and societal perceptions (Mukanga et al., 2023) regarding menstruation and birth control, which impact their understanding of both the physical and mental symptoms associated with these experiences. From a young age, women are often left to navigate these processes without sufficient education or support, leading to confusion, misconceptions, and a lack of empowerment when it comes to managing their reproductive health (Guendelman et al., 2000). The stigma surrounding topics like menstruation and hormonal contraception can further isolate women, making it difficult for them to seek reliable information or openly discuss their …

Family Involvement In Pediatric Occupational Therapy Interventions: A Qualitative Study, Maylee S. Collins

Impacts Of Polyploidization On Endocrine Regulation And Vocalization In The Gray Treefrog Complex, Avery Thigpen

Honors Theses

Comparative genomics data suggest that vertebrates are descendants of ancestral polyploids and that historical polyploidization events fueled evolutionary innovations. For example, polyploidization can modify gene expression patterns and/or increase gene mutation rates to alter the phenotype. While considerable emphasis has been placed on the evolutionary impact of ancient polyploidization events, less is known regarding phenotypic modifications in extant polyploids. I examined circulating levels of adrenal glucocorticoids and gonadal steroids in the diploid-tetraploid gray treefrog complex to understand how polyploidization has impacted hormonal regulation. Furthermore, I examined the relationships between levels of these hormones and acoustic signals to examine if and …

Evolving Enemy Behavior In Video Games, Hermie H. Adams Iii

Honors Theses

The video game I developed for my senior project lacked complex and engaging enemy artificial intelligence. The standard implementations of AI systems such as finite state machines and behavior trees felt like side-steps rather than innovative solutions. Upon seeing the 'magic' of machine learning in perfecting games such as Snake, Super Mario, and Flappy Bird, I was inspired to seek my answer in the field of evolutionary computation. However, my challenge differed in that the problem space would be defined by dynamic player strategies, making it not well-defined or static. As such, my evaluations are based on enemies exhibiting emergent …

The Role Of Presynaptic Proteins In Alcohol Sensitivity And Tolerance, Madhumitha Gundluru

Honors Theses

Mammalian Unc13 (Munc13) and Drosophila Unc13 (Dunc13) are presynaptic active zone proteins essential for synaptic vesicle docking and priming in a neuron. Alcohol binds to the C1 domain of Munc13, which inhibits DAG binding. The reduction in DAG binding by Munc13 decreases the probability of vesicle fusion with the membrane, decreasing neurotransmitter release. Heterozygotes for a Dunc13 loss-of-function allele are behaviorally resistant to alcohol, physiologically resistant to alcohol, molecularly resistant to alcohol, and self-administer significantly more alcohol than control flies. Therefore, genetically reducing Dunc13 mimics a state of alcohol tolerance in the fly. The two main Dunc13 isoforms, Dunc13A and …

Claiming More To Cope: Does Ostracism Increase Overclaiming?, Katy Q. Chen

Honors Theses

In a pre-registered online study, we investigated the relationship between ostracism and overclaiming. Ostracism is the act of deliberately or unintentionally excluding and ignoring others. Overclaiming refers to the behavior of exaggerating one’s knowledge or familiarity with specific topics, often as a way of attempting to present oneself as more knowledgeable or competent than one actually is. Drawing from the temporal need-threat model, we hypothesized that ostracized individuals, as a compensatory response, would likely overclaim more compared to included individuals. This online study simulated a work experience where participants were asked to answer questions about their work-related experiences and opinions. …

Assisted Reproductive Technologies For Southern Cricket Frogs (Acris Gryllus), Audrey Grace Koltz

Honors Theses

Amphibians are facing the most drastic biodiversity declines of all vertebrates, with an estimated 41% of amphibians threatened with extinction. Captive breeding programs employ a variety of assisted reproductive technologies including environmental manipulation, hormonal therapies, artificial fertilization, and gamete preservation to augment vulnerable populations and optimize genetic diversity. Amphibians require a species-specific combination of environmental, social, and physiological cues to reproduce, which makes universal and successful captive breeding programs especially elusive. Here, I investigate assisted reproductive technologies for a small frog species, the southern cricket frog (Acris gryllus). Establishing successful methods for southern cricket frogs may yield promising results for …

Anti-Cancer Activity Of Marine-Derived Fucosylated Chondroitin Sulfates In Ovarian Cancer Cell Spheroid Formation And Notch Signaling Inhibition, Daniella Beiner

Honors Theses

Ovarian cancer is the deadliest gynecological malignancy, with high recurrence rates driven by chemotherapy-resistant cancer stem cells (CSCs). Current therapeutics targeting Notch signaling to inhibit CSC formation have yet to demonstrate clinical benefit and pose risk of gastrointestinal toxicities. Here, we report that treatment with fucosylated chondroitin sulfates (FucCS) inhibited Notch signaling activation and spheroid formation in OVCAR3 ovarian cancer cells. Sulfation and fucosylation were shown to be key structural requirements of this anti-cancer activity. Moreover, this inhibition was synergistic with suppression of Notch glycosylation by Radical Fringe knockout. Preliminary experiments to conjugate FucCS to a maleimide linker in preparation …

The Impact Of Antimicrobial Peptide Depletion And Fungal Infection On Thermal Preference In Green Frogs, Rana Clamitans, Kim M. Salvador

Honors Theses

Climate change and the disease chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), are the two main drivers of amphibian decline worldwide, but it is difficult to predict the outcomes of these interacting stressors. Amphibians are ectotherms meaning they are dependent on environmental temperature for the maintenance of physiological processes, and they rely on behavioral thermoregulation to maintain body temperatures within their thermal limits. As the climate becomes more variable, amphibians are also potentially more susceptible to diseases such as Bd, as their immune defenses, such as antimicrobial peptide (AMP) defenses of the skin, take longer to …
