Kutsi, Alexander Tischer, Siri Froiland, Elizabeth L. Gertz, Jaime L. Jensen, Matthew Auton, Sangita C. Sinha, Christopher L. Colbert

APC Fund Awardees

Gram-negative bacteria utilize siderophores to scavenge for environmental iron. Pseudomonas capeferrum produces the siderophores pseudobactin BN7/8, which trigger cell surface signaling (CSS). Iron import CSS pathways consist of an outer membrane TonBdependent transporter, an inner membrane sigma regulator, and a cytoplasmic sigma factor that activates transcription of target genes. The P. capeferrum sigma regulator, PupR, has an N-terminal antisigma domain (ASD). Previously, the PupR ASD was purified as a dimer in the absence of its cognate sigma factor, PupI. Here we use pulldown assays to demonstrate that His6-PupIFL interacts with the PupR ASD as well as with homodimer-disrupting mutants. We …

Assessment Of Polymeric Chloroquine Formulations For Targeted Therapy Of Ulcerative Colitis And Metastatic Colorectal Cancer, Neha Kumari

Theses & Dissertations

Effective targeted drug delivery is a critical unmet need in the management of both ulcerative colitis and metastatic colorectal cancer, where conventional systemic therapies may be hindered by suboptimal efficacy and significant side effects. This thesis explores the development and preclinical assessment of polymeric chloroquine (PCQ)-based nanotherapeutics, leveraging stimuli-responsive designs for disease-specific delivery and action.

For ulcerative colitis, a reactive oxygen species (ROS)-responsive nanogel system was engineered to release PCQ, a macromolecular derivative of hydroxychloroquine, specifically in the inflamed areas within the colon. Nanogels with well-defined size and positive surface charge were synthesized via reversible fragmentation chain transfer (RAFT) polymerization …

Investigating Metabolic Heterogeneity In Engineered Isogenic Microorganisms, Xinyue Mu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Engineered microorganisms play an increasingly important role in the sustainable production of fuels, bioplastics, and other valuable biomaterials. Successful industrial deployment depends on maximizing product titers and ensuring process robustness at large scale. However, one of the major obstacles is non-genetic cell-to-cell heterogeneity arising from stochastic intracellular processes. Such heterogeneity can result in subpopulations that divert substrates toward growth rather than product biosynthesis, ultimately reducing yield and contributing to batch-to-batch inconsistency. To better understand the mechanisms by which cell-to-cell variation emerges, propagates, and impacts bioproduction, this dissertation investigated how intracellular energetic dynamics and stochastic biosynthetic noise contributed to metabolic heterogeneity …

Probing The Mechanisms Of Reinforcement Learning: Reinforcement Learning, Ventral Striatal Astrocytes, And The Dynamic Coordination Of Information Seeking With Learning, Fatih Sogukpinar

McKelvey School of Engineering Graduate Student Theses & Dissertations

While reinforcement learning has been a vital component in artificial intelligence and machine learning, there exist many open questions about its implementations and how to improve them, in both minds and machines. Among these are i) the contribution of non-neuronal cell types to reinforcement learning, and ii) information-seeking behavior during reinforcement learning. In this thesis, we studied these main topics pertaining to reinforcement learning. In the first chapter, we examined the role of astrocytes in reinforcement learning, and in the second, we investigated human information seeking during reinforcement learning. Neurons in the human and animal brain have been known to …

Exposures, Protections, And Barriers: Advancing Understanding Of Agricultural Worker Health, Alexandra A. Farfalla

Theses & Dissertations

Farming is a hazardous occupation. Exposures are multifactorial, variable, and shaped by overlapping tasks, environments, and social contexts. This dissertation aimed to illustrate the complexity of agricultural exposures and the barriers to protective practices through three complementary studies.

The first study examined co-exposures to solvents and noise as risk factors for hearing loss (HL) among 7,495 farmers and ranchers in a 7-state region. Results indicated nearly 60% of co-exposed participants reported hearing loss, with an adjusted odds ratio nearly six-fold (OR=6.03, [4.67-7.78]) for moderate/severe HL. This work highlights the importance of recognizing chemical exposures as a modality in HL in …

Background

Obesity is associated with systemic inflammation, increasing chronic disease risk. Carotenoids possess anti-inflammatory properties, yet the short-term impact of carotenoid-rich juice intake on inflammation in individuals with obesity remains unclear. Therefore, the purpose of this paper was to examine: (1) participant adherence to a 3-week lycopene-rich juice intervention; (2) variance and effect sizes of responses to the dietary intervention; (3) changes in skin and plasma carotenoids, and inflammatory markers among adults with obesity.

Methods

Twenty-five participants with body mass index (BMI) > 30 kg/m2 were recruited and completed the study. Participants drank 4 ounces (118.3 mL) of study-provided tomato juice, …

The Effect Of Glp-1 Receptor Agonists On Reoperation Following Anterior Cervical Discectomy And Fusion, Nicholas C. Bank, Daniel Whittingslow, Sam Duggan, Joshua L. Morningstar, Douglas S. Weinberg

Student Papers, Posters & Projects

BACKGROUND: Pseudarthrosis remains a significant complication of ACDF, contributing to patient morbidity and increased healthcare costs. Glucagon-like peptide-1 receptor agonists (GLP-1RA), widely prescribed for diabetes and obesity, have been shown to reduced odds of pseudoarthrosis after ACDF. However, it remains unclear whether these reductions meaningfully translate to reduced odds of subsequent cervical surgery.

METHODS: The TriNetX United States Collaborative Network was queried for patients who underwent single- or multi-level ACDF between 2013-2023. Patients with perioperative GLP-1RA use and propensity-score-matched controls without GLP-1RA use were compared for subsequent rates of pseudoarthrosis and cervical reoperation at 6-, 12-, and 24-month intervals. Odds …

Sporadic early-onset Alzheimer’s disease (sEOAD) represents a substantial but less-studied subtype of Alzheimer’s disease (AD). Here, we generated a single-nucleus multiome atlas derived from the postmortem prefrontal cortex, entorhinal cortex, and hippocampus of nine individuals with or without sEOAD. Comprehensive analyses were conducted to delineate cell type–specific transcriptomic changes and linked candidate cis-regulatory elements (cCREs) across brain regions. We prioritized eight conservative transcription factors in glial cells in multiple brain regions, including RFX4 in astrocytes and IKZF1 in microglia, which are implicated in regulating sEOAD-associated genes. Moreover, we identified the top 25 altered intercellular signaling between glial cells …

Duncan NRI Faculty and Staff Publications

Rhizomelic chondrodysplasia punctata type 1 (RCDP1) is a peroxisomal disorder characterized by skeletal shortening, intellectual disability, seizures, cataracts, and reduced lifespans. RCDP1 is caused by biallelic loss-of-function variants in PEX7, which encodes a protein required for importing select enzymes into the peroxisome matrix, including those essential for ether lipid synthesis (e.g., plasmalogens) and the branched-chain fatty acid catabolism. Plasmalogen deficiency is a hallmark of RCDP1 and other peroxisomal disorders, including RCDP types 2-5 (RCDP2-5) and Zellweger spectrum disorders (ZSD). Here, we performed comprehensive metabolomic profiling of clinical samples from RCDP patients and Pex7-deficient mouse models. We identified profound …

Student Publications

The VISIA camera is a device that captures images of the skin, offering a detailed look at skin health by detecting changes that are often missed during physical exams and by the naked eye. It can help identify changes in UV damage, pigmentation, texture, fine lines, and redness. In dermatology, it has become a useful tool to build targeted treatment plans and follow patient progress over time. We present a case of a male patient diagnosed with diffuse scalp actinic keratoses who was treated with topical 5-fluorouracil (5-FU). VISIA images were taken before treatment, at one week, and again three …

Beyond Precision: Ambiomic Survivorship In Childhood And Aya Cancer., Juan Antonio Ortega-García, Omar Shakeel, Nicole Wood, Antonio Pérez-Martínez, Jose Luís Fuster-Soler, Mark D. Miller

Manuscripts, Articles, Book Chapters and Other Papers

Background: Survival among children and adolescents and young adults (AYA) with cancer has improved substantially over recent decades; however, dominant survivorship models remain reactive-activated post-treatment and anchored to static exposure- and organ-based screening. This design underuses the anticipatory window at diagnosis and overlooks environmental and social determinants that modulate outcomes across the life course. Methods: We narratively reviewed international frameworks including the Children's Oncology Group (COG), the International Late Effects of Childhood Cancer Guideline Harmonization Group (IGHG), the Pan-European Network for Care of Survivors after Childhood and Adolescent Cancer (PanCare) and the National Comprehensive Cancer Network (NCCN), and synthesized evidence …

Socrates And Early Buddhist Medical Ethics: Foundations Of Moral Reasoning In The Care Of Body And Mind, Chandima Gangodawila

Budhi: A Journal of Ideas and Culture

While Buddhist traditions articulate a parallel moral vision in the early discourses of the Pāli Canon, Western traditions usually locate the roots of ethical reasoning in Socratic inquiry. Especially in their approaches to bodily care, spiritual well - being, and moral responsibility, this article contends that both Socratic and Early Buddhist ideas converge on fundamental principles in medical ethics. Through a comparative textual and philosophical study, the paper examines how Socratic dialectics and the Buddha's diagnostic approach to dissatisfa ction/ suffering (dukkha) both produce frameworks for ethical healthcare anchored in the development of virtue, wisdom, and care for the integrity …

This study, therefore, focuses on identifying actionable insights that paint a picture of the impact it has on women over the age of 18 in Puerto Rico. In order to achieve this objective, the study relies on a strong theoretical framework that is made up of Foucauldian discourse analysis, necropolitics, and sexual scripts theories. One of the core findings of this research is that Puerto Rico’s colonial history and cultural norms sustain a cycle of …

The Detrimental Impact Of Early Childhood Exposure To Pornography, Leica Marie Estomo

The Scholarship Without Borders Journal

As pornography continues to become more easily and readily accessible, children are at higher risk of viewing it. This work aims to investigate the destructive impact of premature exposure to pornography, and the negative perceptions of sex and decision-making towards it as a result. The operational definition used defines “early exposure” as prepubescents (children of elementary-grade school ages) viewing explicit material through involuntary and accidental initial engagement, and “decision-making” as moral agency and choice of response and action. The populations searched focused more on American culture and its lens on sex and pornography, with the incorporation of other cultural frameworks …
