An Exploration Into Network Analyses Of Motor Behavior, Brain-Computer Interface Control, Arousal States, And An Ischemic Lesion Model, Shashank Anand Mar 2026

An Exploration Into Network Analyses Of Motor Behavior, Brain-Computer Interface Control, Arousal States, And An Ischemic Lesion Model, Shashank Anand

McKelvey School of Engineering Graduate Student Theses & Dissertations

Network-level modelling of neural function incorporates activity in specific brain regions along with a measure of the interactions between these regions (“connectivity”). Connectivity can be assessed through several means, for example through tractography (structural connectivity) or correlated temporal evolution of neural activity (functional connectivity). These analyses have provided valuable insight into several aspects of brain function, such as top-down control, memory, and navigation. This work focuses on studying neural activity within and between several brain regions across different brain states: namely, during motor actions, sensory perception, brain-computer interface engagement, task-free fluctuations in arousal state, and ischemic injury. High gamma (70-170 …

The Prospects Of Car T-Cell Therapies In Changing The Therapeutic Algorithm Of Neurologic Autoimmunities, Marinos C. Dalakas

Department of Neurosurgery Faculty Papers

T cells, genetically modified to express chimeric antigen receptors (CAR T), successfully used in hemato-oncologic malignancies, are showing promising and sustained benefits in refractory autoimmune neurological diseases, including Myasthenia Gravis, stiff-person syndrome, neuromyelitis optica, myositis, autoimmune neuropathies, and multiple sclerosis. Several reported patients with a steadily progressive disease and evolving disability unresponsive to available therapies, including rituximab and new biologics, after 2-3 months of treatment with CARs targeting CD19-positive, antibody-secreting, long-lived plasma cells, and plasmablasts exhibit impressive, long-lasting, and drug-free clinical improvements with the potential for immune reset shifting immunity to a healthy state without the need for continuing more …


Nonlinear Bivariate Associations And Mononuclear Cell‐Type‐Specific Expression Level Differences In The Sting Signalling Pathway, David Kaplan Mar 2026

Nonlinear Bivariate Associations And Mononuclear Cell‐Type‐Specific Expression Level Differences In The Sting Signalling Pathway, David Kaplan

Faculty Scholarship

Understanding intracellular signalling pathways is crucial since they regulate essential functional activities. Bivariate relationships have been useful in delineating these pathways in clinical samples. In our previous studies, we have found many linear associations between pathway components, and we have interpreted these correlations as rheostatic regulators. Increases in an upstream component are correlated with a commensurate downstream increase. Here, we report a quantitative analysis of molecules in the STING pathway by assessing the variance in human peripheral blood mononuclear cell-type-specific molecular expression from patients with atherosclerotic coronary artery disease. The induction of the type I interferon track by this pathway …

From Answers To Understanding: Bridging The Gap Between Multiple-Choice And Open-Ended Questions, Kathleen A. Siren

Teaching and Learning in Communication Sciences & Disorders

Assessment is central to effective teaching, and the structure of exam questions significantly influences both learning and instruction. Multiple-choice (MCQ) and short-answer (SAQ) questions are widely used and frequently studied, each offering distinct advantages and limitations for formative and summative assessment. This study examined a modified multiple-choice format, multiple-choice questions with explanation (MCQwE), for which students selected an answer and briefly explained their reasoning. Designed to combine the efficiency of MCQs with the diagnostic value of open-ended responses, MCQwE were implemented in an undergraduate speech science course and compared to traditional MCQs and SAQs in terms of student performance. Findings …


Intergenerational Hypertension Transmission Before And After South Africa's Democratic Transition, Winfred A. Avogo Mar 2026

Intergenerational Hypertension Transmission Before And After South Africa's Democratic Transition, Winfred A. Avogo

Faculty Publications – Sociology and Anthropology

Background: Apartheid's structural violence produced profound cardiovascular inequalities among Black South Africans through processes that accelerate biological aging ("weathering") and transmit health disadvantage across successive generations. Whether South Africa's 1994 political transition interrupted this intergenerational transmission remains unknown. This study tests whether parent-to-offspring hypertension transmission weakened among cohorts born after apartheid's end, using the 1994 transition as a natural experiment. Methods: This study analyzed 30,438 parent-offspring dyads from five waves (2008–2017) of South Africa's National Income Dynamics Study, representing 11,655 unique offspring aged 18 years and older. Hypertension was defined as blood pressure ≥140/90mmHg or use of antihypertensive medication. Logistic …

School of Integrative Biological & Chemical Sciences Faculty Publications

Currently, there are very few efficient treatment options for hepatobiliary pancreatic cancer (HPC), which comprises pancreatic ductal adenocarcinoma (PDAC), biliary tract cancer (BTC), and hepatocellular carcinoma (HCC). The HPC tumors are the most lethal malignant tumors in the world. Traditional chemotherapy offers little survival benefit and is associated with notable systemic toxicity, which has made antibody–drug conjugates (ADCs) a hopeful treatment option. Strong cytotoxic drugs combine with monoclonal antibodies to attack tumor-associated antigens. This review discusses the benefits and current developments of Antibody–Drug Conjugates (ADCs) in treating HPC. It also covers their mechanisms of action, ongoing clinical trials, and the …

Background: Social vulnerability, dietary fiber, and the gut microbiome have been individually implicated in clinical outcomes for melanoma and sarcoma patients. This study hypothesized that increasing social vulnerability is associated with insufficient dietary fiber intake and negatively associated with microbiome composition and clinical outcomes.

Methods: Clinicopathologic data, baseline fiber intake, and gut microbiome profiles were assessed in 153 patients with melanoma or sarcoma treated with immune checkpoint blockade (ICB) and prospectively followed. Patients' social vulnerability index (SVI) and fiber intake were evaluated for associations with microbiome composition, treatment response, and overall survival (OS).

Results: SVI percentile was 0.4 (interquartile ratio …

Simulated Hearing Loss In Healthy Young And Older Adults Results In Poor Reaction Time In Older Adults., Victoria Kowalewski, Nicoleta Bugnariu, Rita M. Patterson, Jessica Hartos

Pacific Journal of Health

Emerging evidence links hearing loss to increased fall risk in older adults, yet mechanisms remain unclear. This study examined the impact of simulated hearing loss on reactive balance control in healthy young and older adults. Participants performed dual-task scenario involving auditory sentence repetition and unexpected surface translations. Hearing loss was simulated using Adobe Audition, applying frequency-specific attenuation based on moderate sensorineural hearing loss levels from the literature.

Speech-in-noise performance significantly declined under simulated hearing loss for both age groups (p < .001), confirming effective simulation, but not significant differences were found between age groups. Maximum COP-COM displacement (the scalar distance between Center of Pressure and Center of Mass) increased with perturbation intensity (Level 1 vs. Level 2: p < .001), but no significant differences were found between hearing conditions or age groups (p > .05), suggesting compensatory step execution was preserved.

Reaction time analysis revealed a significant interaction between hearing condition and perturbation level …

Cutaneous Rosai-Dorfman Disease Misdiagnosed As Granulomatous Dermatitis: A Diagnostic Pitfall, Sri Naidnur, Jamie Hedrick, Smaran Marupudi, Kara Asbury, Kelly Maedo, Bryan Gammon, Rick Lin

School of Medicine Publications

Cutaneous Rosai-Dorfman disease (CRDD) is an uncommon non-Langerhans cell histiocytosis that may occur without systemic involvement and lacks specific clinical features. We report a 17-year-old female with a slowly enlarging chest lesion initially diagnosed as granulomatous dermatitis on a 4-mm punch biopsy. The lesion was treated as an inflammatory process without improvement. Complete excision revealed a multinodular dermal and subcutaneous infiltrate of large histiocytes demonstrating emperipolesis, confirming CRDD. Systemic evaluation was negative. The initial limited biopsy did not capture defining features, delaying diagnosis.

Persistent nodular lesions that fail to respond to therapy should prompt reconsideration and more representative tissue sampling. …

Gadolinium nanoparticles (GdNPs) have gained increasing attention as multifunctional metal-based nanoplatforms that extend far beyond their traditional use as magnetic resonance imaging (MRI) contrast agents. Their specific magnetic properties, tunable physicochemical features, and tunable biocompatibilities with biocompatible coatings give them great potential as drug delivery and theranostic applications. They offer greater stability, lower systemic toxicity, and more surface modification options compared to molecular gadolinium chelates. The functionalized GdNPs not only show excellent properties as drug carriers for their specific indications but also serve as agents in various imaging modalities with superior therapeutic efficacy by means of radio sensitization and magnetically …


Gastrointestinal Symptoms After Sport-Related Concussion In Irish Athletes, Emma Finnegan, Ed Daly, Katherine Hunzinger, Lisa Ryan Mar 2026

Gastrointestinal Symptoms After Sport-Related Concussion In Irish Athletes, Emma Finnegan, Ed Daly, Katherine Hunzinger, Lisa Ryan

Department of Exercise Science Faculty Papers

Background/Objectives: Sport-related concussion (SRC) elicits multi-systemic symptoms, including nausea, fatigue, and cognitive changes. Gastrointestinal (GI) symptoms are not well captured in current concussion assessments and may be under-recognised in clinical follow-up. GI disturbances may influence intake tolerance and day-to-day fuelling during post-SRC recovery. This study investigated the prevalence and severity of self-reported GI symptoms in Irish athletes after their most recent SRC, examined sex-based patterns, and evaluated the rationale for integrating GI symptom checks into standard concussion tools (e.g., SCAT6) and post-injury monitoring. Methods: An online survey was completed by recreational, competitive, and elite athletes who retrospectively self-reported concussion history, …

Breaking Into Hiv-1'S Epigenetic Vault: Cure Strategies To Eliminate The Viral Reservoir, Joanna Jones, Chelsea Gunderson, Brian Wigdahl, Michael Nonnemacher

Kimmel Cancer Center Faculty Papers

Human immunodeficiency virus type 1 (HIV-1) is a retrovirus that integrates into the host cell's DNA as a provirus. Transcription from the provirus is regulated in large part by cellular proteins and epigenetic factors. These may be repressive or permissive to productive infection. The host factors that regulate this balance are therefore attractive targets for HIV-1 therapeutics. Indeed, proviral chromatin is the focus of two of the current HIV-1 cure strategies. "Shock and Kill" uses latency reversal agents to open the provirus's chromatin, promoting high levels of gene expression that induce the killing of infected cells. "Block and Lock" uses …


Quality Of Prenatal Care, Provider Preference, And Preeclampsia Among African American Women In Georgia, Lyteasha Bass Mar 2026

Quality Of Prenatal Care, Provider Preference, And Preeclampsia Among African American Women In Georgia, Lyteasha Bass

Walden Dissertations and Doctoral Studies

African American women experience disproportionately high rates of preeclampsia in the United States; however, the contributions of prenatal care provider type, health care access, and quality of care to this disparity were insufficiently defined. Guided by the quality health outcomes model, this quantitative case-control study used primary data to examine associations between these factors and the occurrence of preeclampsia among African American women age 18–40 who had given birth within the previous 5 years in Georgia. Descriptive statistics and binary and multinomial logistic regression analyses were conducted. Prenatal care quality was measured using the Quality of Prenatal Care Questionnaire (QPCQ), …

Colorectal cancer (CRC) remains a leading cause of cancer mortality globally, yet current histopathological diagnostics capture only limited features. This study aimed to discover subtle, prognostically significant histomorphological patterns in CRC tissues using unsupervised deep learning. We developed a framework integrating convolutional neural networks with deep clustering, trained on 23,341 image patches from 493 patients. We identified 30 distinct histomorphological clusters from CRC tissue images. Through univariate and multivariate survival analyses, three clusters (Cluster13, Cluster19, and Cluster24) were consistently associated with patient prognosis. These clusters were integrated with clinical factors (T stage, N stage, and differentiation degree) to construct a …

Pan-Cancer Evolution Signatures Link Clonal Expansion To Dynamic Changes In The Tumor Immune Microenvironment, Xinyu Yang, Wei Liu, Geoff Macintyre, Peter Van Loo, Florian Markowetz, Peter Bailey, Ke Yuan

Faculty, Staff and Student Publications

Cancer is an evolutionary process characterized by profound intratumor heterogeneity (ITH), which can be quantified using in silico estimates of cancer cell fractions (CCFs) of tumor-specific somatic mutations. We demonstrate a data-driven approach based on CCF distributions to identify 4 robust pan-cancer evolutionary signatures from 4,146 tumors across 17 cancer types in The Cancer Genome Atlas (TCGA). These signatures define a continuum of cancer cell fractions reflecting neutral evolution, clonal expansion, and clonal fixation. Correlating evolutionary signatures with mutational and biological programs reveals that tumors enriched for clonal expansion and fixation are associated with immune evasion and distinct changes in …

Aging is a major risk factor for heart failure, yet the molecular mechanisms linking cardiac aging to the inflammatory pathophysiology of heart failure remain elusive. Mitochondrial dysfunction and defective organelle quality control are emerging hallmarks of the aging heart, but their biochemical underpinnings are poorly defined. Using comprehensive glycomics, we found that cardiac mitochondria from physiologically aged mice (≥ 20 months) are the major intracellular reservoirs of advanced glycation end products (AGEs), derived primarily from the chemical attack of some α-oxoaldehydes on proteins. This was associated with mild mitochondrial dysfunction and structural remodeling. Lysosomes in aged hearts were enlarged, more …

Chronic inflammatory and degenerative disorders are driven by interconnected immune dysregulation, metabolic instability, epithelial barrier disruption, and impaired tissue repair, limiting the durability of conventional single-target therapies. The global rise in chronic inflammatory, metabolic, and age-related degenerative diseases underscores an urgent need for multi-dimensional therapeutic strategies that move beyond isolated molecular targets. Despite rapid advances in microbiome science and regenerative medicine, these fields have largely evolved in parallel, with limited integration at the translational level. Emerging evidence identifies the gut microbiome as a central regulator of systemic immunometabolic homeostasis through microbial metabolites, barrier integrity modulation, and immune-cell education. In parallel, …

COBRA Preprint Series

Background: An emerging feature in modern biomedical research is collecting and analyzing numerous variables. In the presence of many potential covariates, inference becomes challenging requiring both distinguishing a set of covariates truly associated with an outcome and estimating their corresponding regression coefficients consistently. Traditional statistical inference typically focuses on estimating coefficients assuming a pre-specified set of covariates. Further, advanced machine/statistical learning methods performing both selection and estimation predominantly focus on outcome prediction rather than association inference.

Methods: Motivated by our epidemiological research on long-term childhood cancer survivors, where we aimed to investigate associations between a large pool of longitudinal symptom …

No Effect In Plasma Corticosterone Levels After Observation Of Diseased Conspecifics, B. M. Hardy, M. Chang, S. Mccallum, S. Santangelo, Patricia C. Lopes

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Organisms commonly respond to stressors in their environment by increasing the secretion of corticosterone (CORT). While increased CORT is acknowledged as a response to predation risk by organisms inhabiting a landscape of fear, new research raises the potential for changes in CORT as a response to the risk of infection by organisms in their environment. An increase in CORT of a healthy, uninfected individual in response to their perception of the risk of infection in their environment could change their susceptibility to infection, highlighting a significant role for CORT to alter host–pathogen dynamics. To investigate the effects of infection risk …
