A Potential Klebsiella Bacteriocin With Efficacy Toward The Enterbacteriaceae Family, Kasey Barber

Undergraduate Honors Theses

Drug resistance is unfortunately becoming a prevalent issue in the course of patient treatment, ranging from chemotherapy resistance to antimicrobial resistance. The Centers for Disease Control and Prevention (CDC) estimated in 2016 that at least 23,000 people die every year in the United States from an infection with an antibiotic-resistant organism (Munita, et al, 2016). Carl Friedlander was the first scientist to describe Klebsiella pneumoniae in 1882 as an encapsulated bacillus after isolating the bacterium from the lungs of patients who had died from pneumonia (Ashurst and Dawson, 2022). Klebsiella pneumoniae is the type species for the Klebsiella genus and …

Mathematical Modeling And Examination Into Existing And Emerging Parkinson’S Disease Treatments: Levodopa And Ketamine, Gabrielle Riddlemoser

Undergraduate Honors Theses

Parkinson’s disease (PD) is the second most common neurodegenerative disease across the world, affecting over 6 million people worldwide. This disorder is characterized by the progressive loss of dopaminergic neurons within the substantia nigra pars compacta (SNpc) due to the aggregation of α-synuclein within the brain. Patients with PD develop motor symptoms such as tremors, bradykinesia, and postural instability, as well as a host of non-motor symptoms such as behavioral changes, sleep difficulties, and fatigue. The reduction of dopamine within the brain is the primary cause of these symptoms. The main form of treatment for PD is levodopa, a precursor …

Process Modeling The Neuroprotective Effects Of A Plant-Based Diet On Parkinson's Disease, Julia Mitchell

Undergraduate Honors Theses

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by motor symptoms such as tremors, bradykinesia, rigidity, and postural instability. Recent research suggests an avenue for potential neuroprotection through dietary intervention, specifically the adoption of a plant-based diet. A plant-based diet predominantly comprises foods derived from plants, emphasizing fruits, vegetables, grains, legumes, and nuts while minimizing or excluding animal products. This thesis aims to explore the biochemical pathways implicated in PD progression and the potential impact of dietary choices on these pathways. The investigation focuses on several key pathways: alpha-synuclein aggregation, the blood-brain barrier crossing of levodopa, oxidative stress, ferroptosis, …

Validity And Test-Retest Reliability Of A Digital Dynamic Visual Acuity Test Of Vestibular Function, Lydia F. Grunstra, Courtney D. Hall, Kara D. Stressman

Undergraduate Honors Theses

The vestibular system senses head motion and facilitates gaze stabilization, allowing for clear vision during movement. The vestibulo-ocular reflex (VOR) causes the eyes to move opposite head motion, thus maintaining focus on a target. Consequently, uncompensated loss of vestibular function leads to reduced VOR function resulting in dizziness, nausea, and visual disturbance. Different testing methods have been developed to measure VOR loss. These tests generally require bulky, expensive equipment, and must be performed by a trained examiner. A newly developed digital form of the dynamic visual acuity (DVA) test requires less equipment, is cost-effective, and may be performed at home …

Algorithmic Bias: Causes And Effects On Marginalized Communities, Katrina M. Baha

Undergraduate Honors Theses

Individuals from marginalized backgrounds face different healthcare outcomes due to algorithmic bias in the technological healthcare industry. Algorithmic biases, which are the biases that arise from the set of steps used to solve or analyze a problem, are evident when people from marginalized communities use healthcare technology. For example, many pulse oximeters, which are the medical devices used to measure oxygen saturation in the blood, are not able to accurately read people who have darker skin tones. Thus, people with darker skin tones are not able to receive proper health care due to their pulse oximetry data being inaccurate. This …

Nicotinamide Riboside And Beta-Hydroxybutyrate Activate Parallel Pathways For C. Elegans Lifespan Extension, Mckenzie Peters

Undergraduate Honors Theses

Supplementation with nicotinamide riboside (NR), a form of vitamin B3 and a precursor of nicotinamide adenine dinucleotide (NAD⁺) extends lifespan in the nematode C. elegans and delays aging-related pathologies in mammals. During aging, levels of NAD⁺ decline causing metabolic dysfunction and oxidative damage. Studies in C. elegans found that when NR was administered during larval development it induced the mitochondrial unfolded protein response (UPR^mt), which is frequently associated with lifespan extension. Both calorie restriction (CR) and ketogenic diets (KD) have been shown to extend lifespan, in part through increasing NAD⁺ and through increasing levels …

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker

Undergraduate Honors Theses

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (R_CAP) and length (L_CAP) would be greater in male rats.

Male (n=4) and female (n=4) with intact …

HD symptoms manifest as motor, cognitive, and psychological symptoms that can range of chorea movements to depression or apathy. The disease progresses through various prodromal and clinical stages as the disease starts to manifest. The current technique to diagnose HD is the use of direct genetic testing, which counts the number of repeats. Due to the nature of HD, both …

Treatment Of Allergic Rhinitis: Diphenhydramine Vs. Fexofenadine, Lauren Setzer

Undergraduate Honors Theses

Allergic rhinitis is a growing allergic illness brought on by the inhalation of allergens, resulting in a list of symptoms, including sneezing, watery eyes, runny nose, etc. Among the many treatment options available, H1-antihistamines are a popular choice for allergic rhinitis sufferers. First-generation antihistamines were the first to hit the market and were later discovered to be lipophilic, causing blood-brain barrier penetration and cognitive impairment. Second-generation antihistamines were later developed with lipophobic properties to eliminate any form of cognitive impairment. Both generations are readily available over-the-counter in tablet form, including two commonly used ones: diphenhydramine (Benadryl®) and fexofenadine (Allegra®). These …
