The Influence Of Fermentation Duration And Secondary Fermentation Conditions On The Bioactive Compound Profile Of Kombucha, Jordan Vereen

Honors Theses

Kombucha is a fermented sweet tea produced using a symbiotic culture of bacteria and yeast (SCOBY) and has gained widespread popularity due to its proposed health benefits. Kombucha has been studied to understand these advantages in cardiovascular support, improved metabolism, increased antioxidant effects, enhanced antimicrobial properties, and even potentially slowing the progression of certain diseases. Despite its increasing popularity, the way in which the specific bioactive compounds responsible for these effects and the fermentation conditions that influence their production remain unclear. The present study, conducted in collaboration with Dr. Budner, focuses on quantifying bioactive compounds in kombucha to better understand …

The Legacy Of Lead: Lead Exposure's Harmful Effects And Its Concentration In Poc Communities, Layla Sophronia Barber

Student Theses 2015-Present

This thesis examines the disproportionate burden of lead exposure carried by low income, POC communities. The systemic nature of this problem is a symptom of a longstanding legacy of environmental injustice in the United States. Decades of federal neglect are reflected in the higher statistics of lead exposure and poisoning in predominantly black communities. While it is understood that lead exposure poses a serious threat to physical health and early cognitive development, there is a discouraging lack of urgency to remove the toxin from non-wealthy communities. The material covered by this thesis aims to identify and correct the discriminatory social …

Silence is embedded into the life of medical students. Silence pierces the air when you are standing in the back of a patient room observing the conversation, feet aching, wondering if your presence is unnecessary and overwhelming for the patient. We are transient members of the healthcare team. We contribute to patient medical records with out notes and bedside conversations, yet we lack power in the system---the authority to sign orders, be responsible to true coordination of care, the autonomy that residents wield to make healthcare decisions.

It is easy to lose your sense of self in this silence. We …

Bio 340 Final Project: Rural Population Structure And Food Production Interact To Shape Global Undernourishment, Ava Ripanti

Biology Student Scholarship

Ava Ripanti - Environmental Biology '27

Undernourishment remains a major global public health challenge, reflecting the proportion of a population lacking sufficient dietary energy intake. While food availability is central to food security, undernourishment is also shaped by structural and socioeconomic factors such as population distribution and access to resources. Although rural populations are closely tied to agriculture, they often experience higher food insecurity due to limited infrastructure, market access, and healthcare. Prior research emphasizes that broader determinants, particularly inequality and development, are stronger predictors of undernourishment than agricultural output alone, that food insecurity exists in both rural and urban …

Bacteriophage Therapy For Klebsiella Pneumoniae: Phage Screening And Efficacy Assessment In Macrophages/Neutrophils And Mouse Model, Mounika Duggineni

Biotechnology Theses

Klebsiella pneumoniae causes infections such as pneumonia and urinary tract infections, necessitating alternative therapies. As an emerging MDR pathogen, evaluating newer therapeutic strategies is essential. This study utilized bacteriophages and Klebsiella pneumoniae strains kindly provided by Dr. John, who previously isolated and characterized broad-host-range bacteriophages from hospital wastewater targeting diverse clinical K. pneumoniae isolates. Among fifteen lytic bacteriophages identified across multiple genera, bacteriophage #418 was selected and purified using ultrafiltration, yielding higher functional titers than PEG-based methods. In vitro assays showed Bacteriophage #418 nearly killed bacteria after 2 hours of co-incubation. Ex vivo studies using healthy donors human macrophages …

Hyposense: Multimodal Physiologic And Voc Wearable For Early Hypoglycemia Detection, Nidhi R. Patel

Honors Theses

Hypoglycemia remains a significant safety concern for insulin-dependent individuals, especially when blood glucose declines rapidly during exercise, sleep, or periods of impaired hypoglycemia awareness. Current continuous glucose monitors and automated insulin delivery systems have helped to improve diabetes management, but these technologies primarily respond to glucose trends after they have already started and may not actually provide sufficient warning before symptoms occur. This thesis describes the development of HypoSense, a noninvasive wrist worn wearable concept that is designed to support earlier hypoglycemia risk detection through multimodal physiologic and volatile organic compound emission sensing. HypoSense combines volatile organic compounds/gas sensing with …

Expanding Expanded Access: A Case Of Onc201 And The Ethical Limitations Of Compassionate Use, Ava C. Hutchings

Honors Theses

This study examines the ethical and structural limitations of the Expanded Access program in the United States, with particular focus on its application to terminal pediatric illness. Although the program is intended to provide patients with life-threatening conditions access to investigational therapies outside of clinical trials, its effectiveness in serving critically ill children remains uncertain. This program is analyzed through careful consideration of regulatory review and ethical theory. Key policies governing Expanded Access are examined alongside scholarly discussions of pediatric autonomy and parental authority.

A case study of ONC201, a now-approved investigational drug, is used to illustrate how Expanded Access …

Kevin Kelly, Kevin K. Zarrabi

Department of Medical Oncology Faculty Papers

BACKGROUND: T-cell redirecting therapies, including T-cell engagers (TCEs) and Chimeric Antigen Receptor T-cell (CAR-T), are under investigation in metastatic castration-resistant prostate cancer (mCRPC). Despite their promising therapeutic potential, these therapies remain in early stages of development due to treatment-related adverse events (TRAEs). This study aims to quantify the frequency and severity of adverse events in clinical trials with a pooled analysis.

MATERIALS AND METHODS: A systematic search of PubMed, CINHAL, Scopus, and Ovid was conducted to identify clinical trials evaluating TCEs or CAR-T in patients with mCRPC. Types and frequencies of TRAEs were collected and analyzed using a random-effects model. …

Values-Based Clinical Ethics: A New Model Of Health And Ethics Consultation For Patients Suffering In Extremis, Adam Trainer

Electronic Theses and Dissertations

This dissertation argues that contemporary clinical ethics is inadequately equipped to support patients suffering in extremis because it relies on an insufficiently discriminating account of health and a constrained model of moral reasoning. Drawing on Bernard Lonergan, it reconceives health as an emergent, multi-layered, heuristic notion shaped by biological, psychological, social, and existential goods. On that basis, it critiques principlism’s global applicability thesis and the undergirding claim that its principles form part of the common morality, arguing that this justificatory structure is philosophically insufficient and practically limited for clinical ethics in cases marked by profound suffering, moral plurality, and normative …

Background: Bipolar disorder (BD) is a major mood disorder influenced by both genetic and environmental factors. While DNA methylation from peripheral tissues can reflect both genetic and environmental influences and reveal insights into disease biology, it remains understudied in BD. DNA methylation signatures may complement polygenic scores (PGS) and hold potential as biomarkers. Here, we conducted the largest epigenome-wide association study (EWAS) of BD to date and evaluated the predictive value of polymethylation scores (PMS) in classifying case-control status.

Methods: DNA methylation from peripheral blood of 1729 cases and 1747 controls, comprising twelve cohorts, was obtained. We performed meta-analyses for …

Identifying Novel Gene Dysregulation Associated With Opioid Overdose Death: A Meta-Analysis Of Differential Gene Expression In Human Prefrontal Cortex, Javan K Carter, Bryan C Quach, Caryn Willis, Melyssa S Minto, Dana B Hancock, Janitza Montalvo-Ortiz, Olivia Corradin, Ryan W Logan, Consuelo Walss-Bass, Brion S Maher, Eric Otto Johnson

Faculty, Staff and Student Publications

Only recently have human postmortem brain studies of differential gene expression (DGE) associated with opioid overdose death (OOD) been published; sample sizes from these studies have been modest (N = 40-153). To increase statistical power to identify OOD-associated genes, we leveraged human prefrontal cortex RNA-seq data from four independent OOD studies and conducted a transcriptome-wide DGE meta-analysis (N = 272). Using a unified gene expression data processing and analysis framework across studies, we meta-analyzed 20, 098 genes and found 335 significant differentially expressed genes (DEGs) by OOD status (false discovery rate <  0.05). Of these, 66 DEGs were among the list of 303 genes reported as OOD-associated in prior prefrontal cortex molecular studies (e.g., genes/gene families OPRK1, NPAS4, DUSP, EGR). The remaining 269 DEGs were not previously reported (e.g., NR4A2, SYT1, HCRTR2, BDNF). There was little evidence of genetic drivers for the observed differences in gene expression between opioid addiction cases and controls. Enrichment analyses for the DEGs across molecular pathway and biological process databases highlight an interconnected set of genes and pathways linked to orexin and tyrosine kinase receptors through MEK/ERK/MAPK signaling to affect neuronal plasticity.

Modeling Individual Self-Protective Behavior During Epidemics, Geonsik Yu, Michael J. Garee, Mario Ventresca, Yuehwern Yih

Faculty Publications

Protecting public health from infectious diseases requires collective action, as individual behaviors—such as vaccination and mask-wearing—directly influence disease dynamics. During the COVID-19 pandemic, unexpected public responses often undermined the effectiveness of interventions, highlighting the need to understand collective behavioral patterns and motivations to design more effective mitigation strategies. This study presents an agent-based simulation model that captures how individuals adjust self-protective behaviors based on evolving opinions about disease risk and examines how these decisions interact with external factors, such as public health interventions, to shape collective outcomes. To improve the representativeness of the simulated population, multiple datasets were integrated to …

Progressive Cardiac Phenotypes And Reduced Reversibility From Long-Term Cugexp Rna Expression In A Dm1 Mouse Model, Rong-Chi Hu, Mohammadreza Tabary, Xander Ht Wehrens, Thomas A Cooper

Faculty, Staff and Students Publications

Myotonic dystrophy type 1 (DM1) is caused by an expanded CTG repeat in the DMPK gene, resulting in mutant transcripts that form expanded CUG (CUGexp) RNA foci and sequester muscleblind-like (MBNL) RNA-binding proteins. DM1 is multisystemic, with progressive worsening of disease manifestations in affected tissues. Disease progression is attributed to somatic expansion of the CTG repeats with age, resulting in production of CUGexp RNA with enhanced intrinsic toxicity due to increased MBNL sequestration. To determine the degree to which cardiac disease progression can occur independently of repeat expansion, we used a transgenic DM1 mouse model with inducible heart-specific expression of …

Transition To Noninvasive Testing From The Gold Standard Of Liver Biopsy, Heidi Bien, Sabina Choudhry, Christine Pocha, University Of South Dakota Sanford School Of Medicine & Avera Health System

Scholarship Pathways Program

Purpose: Metabolic dysfunction–associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease, represents a rapidly growing public health concern, affecting roughly 30% of the global population. MASLD encompasses a spectrum from simple steatosis to its more progressive form, metabolic dysfunction–associated steatohepatitis (MASH). Early and accurate assessment of liver disease is critical for risk stratification and management, yet the current gold standard-liver biopsy remains invasive, costly, and limited by sampling variability and interpretive subjectivity. Noninvasive imaging modalities, particularly magnetic resonance elastography (MRE), have emerged as promising alternatives, but their concordance with biopsy in real-world clinical practice remains underexplored.
