BFR cuffs were inflated to 80% of limb occlusion pressure during each work interval and deflated during each recovery. Following each exercise protocol subjects rested for three hours, …
Managing Multi-Drug Resistance: An Evolutionary Game Theory And Optimal Control Approach, Shukhrat Nasrulloev
Managing Multi-Drug Resistance: An Evolutionary Game Theory And Optimal Control Approach, Shukhrat Nasrulloev
Theses and Dissertations
Multi-drug resistance is an evolutionary process in which treatment eliminates sensitive cells, allowing resistant clones to dominate. This thesis investigates this process using a framework integrating population dynamics, evolutionary game theory, and optimal control theory. We develop a two-population logistic growth model describing competition between drug-sensitive and drug-resistant cells under treatment, construct dose-dependent payoff matrices and replicator dynamics to characterize evolutionary competition, and derive a critical drug level Dcrit = (rS - rR)/(dS - dR) at which resistant cells gain a fitness advantage. An optimal control problem is formulated via Pontryagin's Maximum Principle to identify schedules …

Microbiology, Immunology, and Molecular Genetics Faculty Publications
Mycobacterium tuberculosis (Mtb) and nontuberculous mycobacteria (NTM) are acid-fast bacilli that trigger granuloma formation, a hallmark immune response aimed at containing infection. While the biology of Mtb granulomas has been widely investigated, far less is known about granulomas caused by NTM infection, despite the increasing prevalence and clinical challenge of NTM cases worldwide. Because granulomas influence infection control, pathology, and treatment response, understanding their cellular organization and signaling is critical to improving therapeutic strategies. Therefore, we characterized granulomas formed following infection of rhesus macaques with Mycobacterium avium subsp. hominissuis (MAH) and compared them to granulomas from cynomolgus macaques infected with …

Pain And Pace: Investigating Gait Velocity In Individuals With Cancer, Melaina E. Taylor
2026 Honors Symposium
Background: Cancer remains the second leading cause of death worldwide, with incidence rates continuing to rise. Pain, a hallmark symptom of many cancers, is caused by both the progression of disease and treatments. Gait, the way in which someone walks, is now dubbed the “6th vital sign” for its strong relationship with functional status, longevity, and survival. Specifically, gait velocity is a key metric for gait, with previous studies in cancer free adults showing increased pain associated with a decreased gait velocity. The relationship between gait velocity and pain has not yet been explored in individuals with cancer. Purpose: The …

Inpatient Stroke Quality Improvement, Briyawna N. Wyatt
Doctor of Nursing Practice (DNP) Scholarly Projects - Archive
Inpatient nursing documentation for stroke care is essential for meeting quality metrics, maintaining continuity, and supporting timely decisions. Gaps can lead to inconsistent care, metric failures, and reduced staff confidence. This quality improvement initiative aimed to improve metric compliance, documentation consistency, and nursing knowledge and satisfaction. A three-part intervention included targeted education, a standardized documentation verification form, and ongoing feedback from stroke champions. Outcomes measured were metric compliance, knowledge (pre/posttests), documentation completeness (Venous Thromboembolism (VTE), education, Modified Rankin Scale), and staff satisfaction. Results showed significant improvement in nursing knowledge (p < .005), reduced metric fallouts, and better documentation across all indicators. Staff satisfaction increased by about 20%. Overall, combining education, standardized tools, and continuous feedback improved documentation practices, enhanced compliance with stroke metrics, and increased nursing knowledge and satisfaction, supporting better care processes and patient outcomes.

Biomechanical Effects Of Exercise-Based Interventions In Chronic Nonspecific Low Back Pain: A Systematic Review And Meta-Analysis, Lara De Vecchi Machado
Theses and Dissertations--Kinesiology and Health Promotion
Chronic nonspecific low back pain (CNLBP) is the leading cause of years lived with disability worldwide and represents a complex, multifactorial, and heterogeneous condition. It is characterized by substantial interindividual variability in muscle activation patterns, lumbo-pelvic coordination, and movement strategies. Although exercise is widely recommended as a first-line intervention and its clinical benefits are well established, the biomechanical mechanisms underlying functional improvement remain fragmented in the literature and are rarely synthesized quantitatively.
This dissertation conducted a systematic review with meta-analysis to investigate the biomechanical effects of exercise-based interventions in individuals with CNLBP. A total of 39 studies were included and …
Role Of Estrogen Receptor Alpha In Modulating The Circadian System In Female Mice, Victoria Alvord
Role Of Estrogen Receptor Alpha In Modulating The Circadian System In Female Mice, Victoria Alvord
Theses and Dissertations--Biology
Circadian rhythms are approximately 24-hour cycles of physiology and behavior. Circadian rhythms of eating, or meal timing, are linked to cardiometabolic dysfunction in humans. Mistimed eating, such as breakfast skipping and eating late at night, increases the risk of obesity, diabetes, and cardiovascular disease in humans. Likewise, disrupted eating rhythms cause obesity in mice. This dissertation investigates how estrogens regulate eating behavior rhythms and tissue clock timing in female mice. Chapter 1 reviews three key components critical to this work. The first is an overview of the field of chronobiology and the function of the circadian system. The second is …
The Rhesus Macaque Model Of Mycobacterium Avium Infection Reveals That Age-Related Disease Is Due In Part To Chronic Inflammation And Lung Microbial Dysbiosis, Ethan G. Napier
Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics
Aging is associated with dysregulated immunity and increased susceptibility to infection, a phenomenon dubbed as immunosenescence and characterized by reduced naïve T and B cell pools, altered innate immune function, and chronic low-grade inflammation. Nontuberculous mycobacterial (NTM) pulmonary disease (NTMPD) is an increasingly relevant chronic lung infection that disproportionately affects older adults (65+ years) and immunocompromised individuals. However, the host factors underlying increased disease severity in aged patients remain poorly defined. Literature suggests that effective control of NTM relies on coordinated innate and adaptive immune responses, particularly macrophage activation and Th1 cytokine signaling. Using a rhesus macaque model that closely …

Theses and Dissertations--Neuroscience
Long-read single-cell RNA sequencing provides an opportunity to understand human health and disease at isoform resolution, revealing cellular diversity and disease mechanisms difficult to resolve with bulk or short-read methodologies.
Using a modified PIPseq workflow and computational pipeline adapted for Oxford Nanopore (ONT) sequencing, we profiled isoform usage across immune cells, integrating marker expression and isoform discovery, generating the largest long-read single-cell dataset of human immune cells from a single individual to date. We identified non-canonical protein-coding variants of GZMB and CD3G enriched in unexpected cell types. We also discovered novel transcripts from CMC1 and LYAR with cell-type-specific signatures that …
Metabolism As A Regulator Of Sleep And Cortical Activity In Health And Alzheimer’S Disease, Nicholas J. Constantino
Metabolism As A Regulator Of Sleep And Cortical Activity In Health And Alzheimer’S Disease, Nicholas J. Constantino
Theses and Dissertations--Neuroscience
Metabolic flexibility is essential for maintaining normal physiological function, enabling an organism to sense, flux, utilize, and switch fuel sources in response to changing energetic availability, demand, and cellular needs. Energetic demands are state-dependent, with wake and sleep exhibiting distinct metabolic profiles. Sleep is highly sensitive to changes in metabolism and requires metabolic flexibility to both transition into and maintain sleep stability. Alzheimer’s disease (AD) is increasingly recognized as a disease of altered metabolism yet is often framed as a disease of energetic failure. We instead define AD as a disease of metabolic inflexibility, characterized not by insufficient energy availability, …
Design And Advancement Of Analytical Frameworks For In Vivo Single-Photon Calcium Imaging To Characterize Temporal- And Treatment-Dependent Neural Adaptations To Opioid Exposure And Withdrawal In The Medial Prefrontal Cortex, Alexia R. Alsum Dr.
Theses and Dissertations--Pharmacy
Despite the availability of several approved medications for opioid use disorder (OUD), it remains a significant public health concern characterized by persistent neurobiological adaptations that drive relapse and impede successful recovery. The medial prefrontal cortex (mPFC), a region critical for executive control and decision-making, undergoes pronounced functional changes during chronic opioid exposure and withdrawal, yet the cellular mechanisms underlying these adaptations remain poorly understood. This dissertation aims to investigate longitudinal alterations in mPFC neural activity across opioid exposure and withdrawal using in vivo single-photon calcium imaging and newly developed computational frameworks.
Following standard preprocessing to extract and normalize calcium traces, …
Molecular Mechanisms And Metabolic Consequences Of Glucocorticoid Resistance, Genesee J. Martinez
Molecular Mechanisms And Metabolic Consequences Of Glucocorticoid Resistance, Genesee J. Martinez
Theses and Dissertations--Pharmacology and Nutritional Sciences
Glucocorticoids are vital steroid hormones that govern metabolism, stress responses, and immune functions through intricate, tissue-specific mechanisms, both genomic and non-genomic. These hormones bind to the glucocorticoid receptor (GR), which then acts as a transcription factor to modulate gene expression. Chronic elevation of glucocorticoid levels may lead to glucocorticoid resistance, resulting in adiposity, inflammation, and insulin resistance, thereby adversely affecting multiple metabolic tissues. Whether produced endogenously or administered exogenously, excessive, chronic glucocorticoid concentrations impair glucocorticoid signaling. Although there are two primary isoforms of the receptor, GR⍺ and GRβ, only GR⍺ interacts with glucocorticoids.Through the research conducted in this dissertation, we …
Expanding The Role Of Muscle Stem Cell Fusion In Muscle Under Hypertrophic Stimulus, Jensen Goh Zhong Sheng
Expanding The Role Of Muscle Stem Cell Fusion In Muscle Under Hypertrophic Stimulus, Jensen Goh Zhong Sheng
Theses and Dissertations--Physiology
Muscle stem cells (MuSCs) are a unique stem cell population that can activate in response to both injury and growth stimuli. Studies on muscle regeneration have shown MuSC activation follows a uniform progression through proliferation, differentiation, and fusion. Therefore, to determine whether MuSC replication is a prerequisite for differentiation under hypertrophic stimulus, I used a lineage-tracking mouse model (Pax7rtTA; TRE-H2B-GFP) to label MuSC nuclei and simultaneously tracked DNA synthesis via EdU incorporation. This dual-labeling approach allowed us to not only distinguish MuSC-derived nuclei but also demarcate which MuSC had proliferated prior to fusion. I then employed a mechanical …
A Tale Of Two Serpins: Pathologic And Protective Roles Of Agt And Pai-1 In Metabolic And Cardiovascular Disease, Alex C. Pettey
A Tale Of Two Serpins: Pathologic And Protective Roles Of Agt And Pai-1 In Metabolic And Cardiovascular Disease, Alex C. Pettey
Theses and Dissertations--Physiology
Metabolic and cardiovascular diseases are leading causes of morbidity and mortality worldwide. Conditions such as metabolic dysfunction-associated steatotic liver disease (MASLD), aortic aneurysm, and cardiac fibrosis have limited pharmacological therapies, underscoring the need for deeper mechanistic investigations. Serine protease inhibitors (serpins) have been implicated in these pathologies and represent potential therapeutic targets. Despite structural homology, serpins regulate diverse physiological processes through both protease inhibition and non-inhibitory mechanisms. This dissertation examines the roles of two serpins, angiotensinogen (AGT) and plasminogen activator inhibitor-1 (PAI-1), in preclinical models of metabolic and cardiovascular disease to identify novel mechanisms that may inform future therapeutic strategies. …
Investigation Into The A/Ss Of Cervical Cancer And Its Effects On Tumor Control Probability In Radiation Therapy, Cameron Thayer-Freeman
Investigation Into The A/Ss Of Cervical Cancer And Its Effects On Tumor Control Probability In Radiation Therapy, Cameron Thayer-Freeman
Theses and Dissertations--Radiation Medicine
The standard of care for locally advanced cervical cancer is chemoradiation, consisting of conventional external beam therapy (EBT) followed by a boost of high dose rate (HDR) brachytherapy. These two radiation treatments will illicit different degrees of biological response depending on the tissue in question, and quantifying the overall effect the combined treatments will have require some form of biological modeling. The linear quadratic (LQ) model of cell survival is the most widely used radiobiological model in clinics across the nation.
It is quantified by the parameters a and ß, which model how radiation generates lethal damage in a population …

Managing Dietary Nonstructural Carbohydrates In Insulin Dysregulated Horses: Pasture, Long-Stem Forage, And Restrictive Grazing Strategies, Morgan J. Askins
Theses and Dissertations--Veterinary Science
Insulin dysregulation (ID) is a complex endocrine disorder, impacting a large percentage of the equine population. ID is the defining characteristic of equine metabolic syndrome (EMS). Within the various classifications of EMS horses, the commonality is ID and their higher risk of laminitis. To mitigate insulin response and laminitis risk in ID horses, current management focuses on restricting pasture exposure and feeding low nonstructural carbohydrate (NSC) rations. Minimal studies have evaluated how ID horses respond to pasture of various NSC, long-stem forages, and restrictive grazing strategies. Providing horse owners and managers with improved nutritional management recommendations for ID horses with …
Using Camera-Based Unmarked Spatial Capture-Recapture Modeling To Estimate Reintroduced Elk (Cervus Canadensis) Population Parameters And Distribution In Southeastern Kentucky, Claire Marie Muia
Theses and Dissertations--Forestry and Natural Resources
Estimation of population parameters is important for wildlife management decisions. Elk reintroduced to southeastern Kentucky experienced early irruptive population growth and are currently monitored using a statewide harvest-based statistical population reconstruction model (SPR) across the Kentucky Elk Restoration Zone (KERZ). Because the SPR model is spatially coarse and difficult to scale to the smaller management units comprising the KERZ, we conducted a spatially explicit capture-recapture study using a clustered camera-trapping array deployed for 10 weeks from June–August 2024 to estimate elk population parameters within Management Unit 4. Due to a lack of resights of GPS-marked elk, population parameters were estimated …

Non-Invasive Detection Of Intracranial Pressure, Andrei V. Nesterenko
Non-Invasive Detection Of Intracranial Pressure, Andrei V. Nesterenko
Honors Undergraduate Theses
Intracranial pressure is a critical metric used when managing tumors, strokes, TBIs, hydrocephalus, and other operative conditions. Traditional methods for continuous ICP monitoring, intraparenchymal catheters, epidural transducers etc., are invasive and carry a high risk of infection. Previous attempts to create accurate, easy to use, and non-invasive ICP monitoring techniques have been unsuccessful. In this study, we investigated the utility of supraorbital and posterior auricular photoplethysmography to monitor changes in ICP during orthostatic tilt and hyperventilation, which increase and decrease ICP respectively.
Through a continuous 5-minute recording on a tilt-table we characterized SOA and PAA waveforms in 12 participants (ages …

Manuscripts, Articles, Book Chapters and Other Papers
Juvenile idiopathic arthritis (JIA) is a chronic autoimmune disease that negatively affects ~100,000 children under the age of 16 in the United States. About ~30% of these patients fail first-line drug therapy with low-dose methotrexate (MTX) due to poor tolerability or lack of efficacy. The SLCO1B1*14 allele is associated with increased MTX clearance and has been linked to reduced overall drug exposure and nonresponse to MTX in JIA patients. Herein, we describe transgenic hSLCO1B1*14 and hSLCO1B1*1 DBA1/J mSlco1b2 knock-out mice, which we used to assess arthritic response to MTX using the collagen-induced arthritis model. Mass spectrometry-based proteomics analysis revealed that …
