Platelet Gαz Regulates Ovarian Tumor Growth And Mediates The Effects Of Chronic Stress, María G. Torres Carrizalez May 2026

Platelet Gαz Regulates Ovarian Tumor Growth And Mediates The Effects Of Chronic Stress, María G. Torres Carrizalez

Dissertations and Theses (Open Access)

Ovarian cancer is the most aggressive gynecologic cancer, with 12,450 estimated deaths in 2026. Elevated platelet counts are commonly observed in patients with ovarian cancer and are associated with enhanced tumor growth and poor prognosis. Patients with ovarian cancer are frequently exposed to elevated levels of stress, which has been correlated with accelerated disease progression and increased mortality. Interestingly, the platelet Gαz protein is activated by epinephrine through the α2A-adrenergic receptor, suggesting a potential mechanistic link between stress signaling and platelet-driven tumor progression. To investigate this, I evaluated the role of platelet Gαz in ovarian cancer using control (Gzfl/fl …


Abnormal Trafficking And Processing Of Multiple Matrix Metalloproteinases Drive Cartilage Defects In Congenital Disorders Of Glycosylation, Chia-Lun Wu May 2026

Abnormal Trafficking And Processing Of Multiple Matrix Metalloproteinases Drive Cartilage Defects In Congenital Disorders Of Glycosylation, Chia-Lun Wu

All Dissertations

Congenital Disorders of Glycosylation (CDG) are rare metabolic diseases caused by defects in glycosylation. Despite identification of over 200 CDG types, the mechanisms linking glycosylation defects to diverse clinical phenotypes remain unclear. This dissertation uses zebrafish models of PMM2-CDG and STT3-CDG to redefine CDG pathogenesis, shifting from a simple glycan deficiency model to one involving disrupted cellular spatial organization.

We identify a protease-dependent pathway underlying craniofacial cartilage defects. Specifically, defective proteolytic processing of N-cadherin, a key adhesion molecule in chondrogenesis, is a central driver of pathology. We further uncover an unconventional trafficking mechanism in which ER stress and altered secretory …


From Synapse To Circuit: Mechanisms Of Behavioral Flexibility And Its Restoration After Prenatal Alcohol Exposure, Jayapriya Chandrasekaran May 2026

From Synapse To Circuit: Mechanisms Of Behavioral Flexibility And Its Restoration After Prenatal Alcohol Exposure, Jayapriya Chandrasekaran

Biomedical Sciences ETDs

Behavioral flexibility—the ability to adapt behavior when contingencies change—is a fundamental executive function supported by orbitofrontal–striatal circuitry. This dissertation examined molecular, motivational, and circuit mechanisms underlying flexibility and its restoration after prenatal alcohol exposure (PAE). In healthy mice, GluN2B-containing NMDA receptors in the orbitofrontal cortex increased during outcome updating, while AMPA receptor subunits in the dorsal striatum rose during new learning, defining temporally distinct plasticity processes. PAE impaired reversal learning under low-reward conditions, but not when motivation was high, indicating altered thresholds for circuit engagement rather than permanent loss. Finally, optogenetic stimulation of OFC→dorsal striatum projections rescued flexibility in PAE …


In-Vitro Testing Of Light Wavelength To Detect Clots In Neonatal Extracorporeal Membrane Oxygenation Circuitry, Amanda Holmes May 2026

In-Vitro Testing Of Light Wavelength To Detect Clots In Neonatal Extracorporeal Membrane Oxygenation Circuitry, Amanda Holmes

Dissertations and Theses (Open Access)

Background: Neonates requiring extracorporeal membrane oxygenation (ECMO) are at high risk for thrombotic complications, which contribute substantially to morbidity and mortality. Current circuit surveillance methods rely on intermittent visual inspection and indirect laboratory markers, both of which often detect thrombosis only after clinically significant progression. Optical approaches offer a non-invasive alternative for earlier clot visualization, yet the influence of illumination wavelength on detection performance under realistic ECMO conditions remains incompletely characterized.

Methods: This study evaluated wavelength-dependent clot detection performance in a controlled in-vitro neonatal ECMO circuit model using a portable imaging prototype designed to emulate bedside workflow. Twelve independent ECMO …

Adhesion G protein-coupled receptors (aGPCRs) constitute a structurally and functionally distinct group within the superfamily of GPCRs. In 2015, the International Union of Pharmacology invited the Adhesion GPCR Consortium to publish a comprehensive review about aGPCRs and establish a unified nomenclature. Since then, substantial progress has been made in delineating the biological roles, molecular architecture, biochemical properties, expression profiles, ligand repertoire, and activation and signaling strategies of aGPCRs. Commensurate with these advances, their relevance to human pathophysiology has become increasingly apparent. In a coordinated effort, the Adhesion GPCR Consortium has reviewed recent progress in this field and provides a comprehensive …


Social Correlates Of Trauma And Posttraumatic Stress Disorder: The Importance Of Context, Lukoye Atwoli, Linnet Ongeri May 2026

Social Correlates Of Trauma And Posttraumatic Stress Disorder: The Importance Of Context, Lukoye Atwoli, Linnet Ongeri

Internal Medicine, East Africa

Understanding trauma and posttraumatic stress disorder (PTSD) requires a contextual perspective that considers historical legacies, social environments, and cultural realities. This paper draws on empirical evidence from Kenya and Uganda to demonstrate the limitations of applying trauma frameworks developed in high-income countries to African contexts. Findings from the Orphaned and Separated Children’s Assessment Related to Their Health and Well-Being (OSCAR) study challenge assumptions about care environments. The study reveals higher PTSD rates among orphans in family-based settings compared to institutional care, and highlights the protective roles of religion and social support. The Neuropsychiatric Genetics of African Populations-Psychosis (NeuroGAP-Psychosis) study provides …


Surgical Timing After Acromioclavicular Joint Separation: Association With Clinical Outcomes, Mallory B Lane, Jacob Siahaan, James M Gregory May 2026

Surgical Timing After Acromioclavicular Joint Separation: Association With Clinical Outcomes, Mallory B Lane, Jacob Siahaan, James M Gregory

Faculty, Staff and Student Publications

Background: Treatment of acromioclavicular joint (ACJ) separations continually lacks consensus between providers, and while low-grade injuries generally respond well to conservative management, high-grade injury management is more complex. For patients requiring surgery, the effect of the timing of surgery with respect to the original injury on clinical outcomes remains unclear.

Hypothesis: Clinical outcome measures would worsen as the time between ACJ dislocation injury and surgery increased.

Study design: Cohort study; Level of evidence, 3.

Methods: A large nationwide insurance claims database was queried for patients who had an ACJ dislocation injury using International Classification of Diseases, Ninth and Tenth Revision …

Factors Influencing Patient Recall For Follow-Up In The Multi-Stage Deployment Of Medical Intelligent Screening Systems, Wenjie Chen

Dissertations and Theses Collection (Open Access)

With the deep integration of artificial intelligence (AI) technology in the healthcare sector, intelligent screening systems have achieved significant breakthroughs in predictive accuracy; however, they commonly face a management challenge in clinical implementation: accurate early warnings but limited patient recall. To address this ineffective technological empowerment issue in practice, this study proposes a theoretical framework featuringbidirectional interactions between "technological empowerment" and"relational empowerment" based on empowerment theory to systematicallyinvestigate the dynamic evolution mechanisms and boundary conditions of patient recall willingness under multi-stage, cross-departmental deployment of medical intelligent screening systems. Using a leading municipal hospital as the primary experimental setting, the study …

Predictors Of Elevated Borderline Personality Disorder And Pai-Bor Scores: The Role Of Psychological, Trauma, And Treatment Factors, Isabel Avendano Gil

Electronic Theses and Dissertations

Borderline Personality Disorder (BPD) is a complex and multifaceted mental health condition that significantly affects individuals' emotional, cognitive, and interpersonal functioning. BPD is characterized by impulsivity, emotional dysregulation, unstable relationships, and self-destructive behaviors, and often results in significant impairment across multiple life domains. Previous research has consistently identified Adverse Childhood Experiences (ACEs), particularly sexual abuse (SA), as key contributors to the development of BPD. These early traumas are closely associated with core features of the disorder, including affective instability, identity disturbance, impulsivity, and maladaptive interpersonal patterns.

Psychotherapeutic interventions, such as Dialectical Behavior Therapy (DBT) and Cognitive Behavioral Therapy (CBT), have …

Exploring Policy Change To Support Early Diagnosis Of Congenital Heart Defects (Chd) In New Mexico, Kelsey Carson Leibenhaut

Doctor of Nursing Practice Scholarly Projects

Congenital heart disease (CHD) is not a new or rare problem; it has likely always been a leading cause of childhood morbidity and mortality and clocks in today as the most frequently occurring birth defect, affecting an estimated 1 in 100 newborns (CDC, 2025). Prior to the middle of the 20th century, there was little to be done about CHD, as no treatments existed. Everything changed with the advancement of options for surgical repair of CHDs, significantly prolonging lifespans and improving quality of life for affected individuals. Despite these incredible advancements, babies are born with CHD every day, leading to …

Comparison Of Age Distribution Among Individuals Experiencing Homelessness: Local And National Perspectives, Alexandria Cross, Samantha Somiah

Undergraduate Honors Theses

Individuals experiencing homelessness represent a vulnerable population facing significant health and social challenges across the United States. Although people of all ages are affected, certain age groups are disproportionately represented. National data indicate that adults aged 35-54 make up the largest community of individuals experiencing homelessness, with a growing number of adults aged 55 and older. However, less is known about how these national trends compare to local populations, particularly in Appalachia. The purpose of this study is to compare the age distribution between individuals experiencing homelessness at the national level with local data from northeast Tennessee to identify potential …


Associations Between Controlling Coaching Behaviors And Mental Health Help Seeking Attitudes In Collegiate Athletes, Maria C. Cacheiro May 2026

Associations Between Controlling Coaching Behaviors And Mental Health Help Seeking Attitudes In Collegiate Athletes, Maria C. Cacheiro

Undergraduate Honors Theses

Although correlations between coaching behaviors and mental health have been investigated before, research that extensively analyzes collegiate athletes’ willingness to seek out mental healthcare has not been conducted. Previous research shows that coaching behaviors correlate with athlete mental health and even predict depression levels more accurately than their own personality traits. The current study aimed to analyze the relationship between athletes’ perceived controlling coaching behaviors and their mental health-help seeking attitudes. Participants were surveyed to determine their perception of controlling coaching behaviors, available emotional support, athlete-coach relationship satisfaction, and mental health seeking attitudes. It was found that perceived aspects of …

Molecular Mechanisms Of Pfas Induced Protein Dysfunction: Implications For Neurodegenerative Risk, Daisy Lee Wilson May 2026

Molecular Mechanisms Of Pfas Induced Protein Dysfunction: Implications For Neurodegenerative Risk, Daisy Lee Wilson

Open Access Theses & Dissertations

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants with widespread human exposure and well-established links to adverse health outcomes. However, despite increasing epidemiological and experimental evidence, the molecular mechanisms underlying PFAS-induced neurotoxicity remain incompletely defined. This dissertation investigates PFAS toxicity across biological scales, integrating protein biophysics with neuronal cell models to elucidate pathways relevant to neurodegeneration. At the molecular level, we demonstrate that PFAS disrupts the structure and function of globular proteins, including the impairment of α-lactalbumin's calcium-binding capacity and of β-lactoglobulin's retinol binding, through concentration-dependent conformational destabilization. By applying these findings to a neuronal model, we show that …

Health disparities among low-income Hispanic immigrants in the United States are shaped by complex interactions between acculturation, structural inequality, and socio-cultural determinants that behavioral and epidemiological models have not fully explained. This dissertation examines the relationship between acculturation and obesity-related outcomes among uninsured and low-income Hispanic adults of Mexican descent in El Paso, Texas, using a three-article, sequential, explanatory, mixed-methods design grounded in Latina/o Critical Race Theory (LatCrit).Article 1 presents a systematic review of 20 peer-reviewed studies examining acculturation and obesity among Mexican Americans, finding consistent evidence that longer U.S. residence is associated with increased BMI and obesity prevalence, mediated …


Determining Zap-70 Signaling Pathways Mediated By Ccr7 In Tcr T Cell Activation, Vivian Torres May 2026

Determining Zap-70 Signaling Pathways Mediated By Ccr7 In Tcr T Cell Activation, Vivian Torres

Open Access Theses & Dissertations

Activation of T lymphocytes is the main event that occurs in the adaptive immune response after engagement of the T cell receptor (TCR) with the peptide of the major histocompatibility complex (pMHC) molecules that are demonstrated by antigen presenting cells [1]. A key step in this process is the recruitment and activation of the zeta chain associated protein of 70 kDa (ZAP-70). ZAP-70 couples TCR engagement to downstream intracellular signaling pathways through phosphorylation of tyrosine residues within intracellular tyrosine activation motifs (ITAMs) [2]. Although there have been extensive studies on the signaling response through TCR activation, the regulatory influence of …

Optimized Ultrasound Imaging Of Phase-Change Nanodroplets, Charles R Dyall, Dmitry Nevozhay, Andy Liu, Trevor M Mitcham, George J Lu, Konstantin V Sokolov, Richard R Bouchard

Faculty, Staff and Student Publications

Phase-change nanodroplets (PCNDs) continue to generate significant research interest due to their potential to extravasate into tissue, to be targeted for molecular imaging and drug delivery, and to undergo an induced phase-change to "activated" microbubbles (MBs) for ultrasound (US) imaging. To accurately quantify molecular markers, however, one assumes a consistent proportion of PCNDs in a region of interest (ROI) are stably activated and imaged. Herein we present a framework for developing a diagnostic sequence that is optimized for PCND activation uniformity, contrast, and acquisition time. To develop this framework, activation was examined at three scales of increasing complexity: single, adjacent, …

There is much interest in the role of sweeteners such as table sugar (sucrose) and high-fructose corn syrup in obesity and metabolic disease. Both sweeteners consist of glucose and fructose, two six-carbon isomeric sugars. Whereas glucose ingestion may promote obesity through its effects to stimulate insulin secretion, fructose has unique metabolic effects that promote triglyceride synthesis and fat accumulation. These effects arise from fructose's well-known role as a signal of metabolic plenty. Under modern conditions of overnutrition, chronic excess fructose drives features of metabolic syndrome. Emerging evidence further links fructose to cancer and dementia. Here we review the biochemical, molecular …

Introduction: Rare, deleterious germline variants are key contributors to inherited lung cancer (LC) risk. The Genetic Epidemiology of LC Consortium (GELCC) has curated valuable high-risk LC families and is uniquely positioned to uncover rare, high-penetrance variants underlying familial LC (FLC).

Methods: We performed whole-genome and exome sequencing on germline DNA from 120 high-risk LC families (177 FLC cases, 309 unaffected relatives). We prioritized rare (allele frequency < 1% in the genome aggregation database), potentially deleterious variants present in two or more FLC cases. These variants were then validated in 10,085 sporadic LC (SLC) cases and 612,970 controls.

Results: We identified 118 candidate variants, 28 of which were validated in SLC with strong statistical support. We discovered a novel pathogenic axis of three truncating variants in GALNT6, MUC4, and ERBB3 genes, which …

The digestive system is essential for nutrient absorption, processing, and waste elimination. The expression of many genes and physiological processes within this system exhibits a 24-h rhythmicity. However, modern lifestyle factors, such as jet lag, shift work, and irregular eating patterns, significantly disrupt these rhythms, triggering various stress responses and contributing to numerous digestive disorders. Here, we focus on emerging studies on noncanonical clock regulators involved in stress responses, integrate these novel findings into the established model of the core circadian clock, and highlight recent advances in the development of novel therapeutics targeting these 24-h regulators. In addition, we discuss …

Stochastic Universal Differential Equations For Epidemiological Modeling: Uncertainty Quantification In Disease Transmission Dynamics, Alice Menaya Armah-Bonney May 2026

Stochastic Universal Differential Equations For Epidemiological Modeling: Uncertainty Quantification In Disease Transmission Dynamics, Alice Menaya Armah-Bonney

Electronic Theses and Dissertations

Epidemic forecasting requires not only predictions of expected case counts, but also quantification of uncertainty, although existing surrogate modeling frameworks for agent-based models remain fundamentally deterministic. In this thesis a Stochastic Universal Differential Equation framework is presented that extends the deterministic Universal Differential Equation approach by incorporating a learnable stochastic diffusion term, enabling calibrated probabilistic forecasts while preserving the mechanistic interpretability and computational efficiency of the deterministic baseline. In doing so, a two-phase training algorithm is introduced to ensure stable convergence and the framework is validated against the ensemble output from ExaEpi, an exascale agent-based model of a COVID-19 outbreak …

Bergsonian Blend: Subjective Temporality Within Modernist Aesthetics Of Mental Illness, Lydia Victoria Gervais May 2026

Bergsonian Blend: Subjective Temporality Within Modernist Aesthetics Of Mental Illness, Lydia Victoria Gervais

Electronic Theses and Dissertations

Henri Bergson was a modernist French philosopher who wrote extensively on the topic of the lived experience of time, which he called durée, or duration. His contemporary, Sigmund Freud, was developing psychoanalytic theory in a growing field of psychological study, which serves as a prominent ancestor to modern psychiatry and current psychoanalytical literary studies. Fiction writers of the 1900s absorbed the zeitgeist of melded chronology and consciousness, interweaving themes of time and trauma in their works. Utilizing Henri Bergson’s durée as a philosophical framework, I examine the moralization of time-consciousness in connection with mental illness and investigate representations of …

UNLABELLED: The NRF2 transcription factor is constitutively active in cancer, in which it functions to maintain oxidative homeostasis and reprogram cellular metabolism. NRF2-active tumors exhibit NRF2 dependency and resistance to chemotherapy/radiotherapy (RT). In this study, we characterize VVD-065, a first-in-class NRF2 inhibitor that acts via an unprecedented allosteric molecular glue mechanism. In the absence of stress or mutation, NRF2 is rapidly degraded by the Kelch-like ECH-associated protein 1 (KEAP1)-cullin3 (CUL3) ubiquitin-ligase complex. VVD-065 specifically and covalently engages Cys151 on KEAP1, which in turn promotes KEAP1-CUL3 complex formation, leading to enhancement of NRF2 degradation. Previously reported Cys151-directed compounds decrease KEAP1-CUL3 interactions …

BACKGROUND: Women's lacrosse is an increasingly popular sport. Current rules allow incidental body and stick-to-stick contact, with limited required protective equipment. Injuries to the head, face, and lower extremities are common, especially at higher levels of competition. Differences in injury rates and types based on competition level remain largely unknown.

PURPOSE: To systematically review the literature to better understand injury differences between scholastic and collegiate female lacrosse athletes.

STUDY DESIGN: Systematic review; Level of evidence, 4.

METHODS: Under PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses), 543 studies were identified in September 2025 in PubMed, Scopus, Google Scholar, …
