Exploring Hexavalent Chromium Exposure And Lipid Accumulation In Liver Disease., Gabrielle Celine Griffin

Electronic Theses and Dissertations

The prevalence of MASLD has doubled over the past 20 years and continues to rise. Hexavalent chromium [Cr(VI)], a top chemical hazard in U.S. drinking water, is emerging as potential risk factor for liver disease. To study the impact of Cr(VI) and high-fat diet on MASLD, we developed an in vivo model using Sprague-Dawley rats exposed to Cr(VI) in drinking water (0, 0.05, or 0.1 mg/L) and fed normal or high-fat diet for 90 days. High-fat diet significantly increased body mass, plasma lipoproteins, cholesterol, liver injury, and hepatic triglycerides, which were exacerbated by Cr(VI) exposure. Cr(VI) alone increased hepatic chromium …

Analysis Of An Ethanol Sensitive Bmp-Nkx2.3-Fgf Signaling Pathway In Pouch Morphogenesis., Hieu Dai Le Vo

Electronic Theses and Dissertations

Craniofacial malformations lie at the heart of Fetal Alcohol Spectrum Disorders (FASD). While there is growing evidence for a genetic component to FASD, little is known of the cellular mechanisms underlying these ethanol-sensitive loci in facial development. Bone Morphogenetic Protein (Bmp) signaling pathway dependent pouch formation is a key mechanism in facial development. We have previously shown that multiple Bmp mutants are sensitized to ethanol-induced facial defects. However, ethanol does not directly impact Bmp signaling. This suggests that downstream effectors, like nkx2.3 and Fibroblast Growth Factor (Fgf) signaling, may mediate the impact of ethanol on Bmp mutants. Here, I …

Understanding The Potential Impact Of Ostracism On Lgbtq Health Disparities, Ellen D.B. Riggle

Political Science Faculty Publications

Research finds harmful impacts of ostracism on the health and well-being of the ostracized individual (as well as the ostracizer and members of the community). While often conceptualized as social (interpersonal), ostracism may originate at multiple levels of the socio-ecological system, including forms of political and institutional ostracism. The ostracism of LGBTQ people originates in cultural stigma and is reproduced and reinforced at all levels, from discriminatory laws and institutional policies (e.g., workplace, educational), to the actions of community or family members, to interactions with strangers. Ostracism, acute and chronic, creates increased risk for psychological and physical harm to LGBTQ …

Human Salivary Gland Stem/Progenitor Cells For Tissue Engineering, Sars-Cov-2 Susceptibility, And Neurointegration, Caitlynn Barrows

Dissertations and Theses (Open Access)

Salivary glands and the saliva they secrete are important for digestion, chewing, and maintaining oral health. Reduced saliva production leads to a decreased quality of life for patients experiencing hyposalivation as a result of disease or injury, thus a large effort has been dedicated to developing materials and medium to recapitulate the structure of the gland for regenerative medicine. In doing so, we have come closer to developing a more complex model to study disease. These models, however, do not yet fully recapitulate the gland. In this dissertation, we describe a new cell source that can be used to develop …

Integrating Bulk And Single-Cell Transcriptomics To Investigate Intratumor Heterogeneity, Shuai Guo

Dissertations and Theses (Open Access)

Cancers are heterogeneous mixtures of tumor and surrounding cells, where each component comprises multiple distinct sub-types and/or states. Understanding the cell-type-specific contributions is critical for advancing cancer biology, yet high-throughput expression profiles from tumor tissues only represent combined signals from all diverse cellular sources. Bulk deconvolution with single-cell/nucleus (sc/sn) RNA-seq data has emerged as a powerful approach to dissect both cellular composition and cell-type-specific expression patterns, yet the technological discrepancy across sequencing platforms limits accuracy.

To systematically evaluate the impact of platform discrepancies on bulk deconvolution, we first generated a benchmark dataset of 24 healthy retinas with paired bulk and …

Clonal Phenotype Mapping Reveals Genomic Alterations Underlying Tumor Immunosuppression During Immunotherapy, Er-Yen Yen

Dissertations and Theses (Open Access)

Tumors are dynamic ecosystems that evolve under selective pressures, shaping their ability to either elicit or evade immune responses. In pancreatic ductal adenocarcinoma (PDAC), where immunotherapy has yet to become an effective treatment option, we investigated the role of intratumoral heterogeneity in influencing immune interactions. Using orthotopic clonal replica tumors, we tracked clonal dynamics in response to anti-PD1 therapy and found that while treatment had limited impact on overall tumor volume, it induced profound shifts in clonal composition. Spatial lineage analysis of treatment-naïve tumors revealed that clones with distinct immunotherapy sensitivities occupy unique tumor microenvironments, a pattern that remained stable …

Chronic Cluster Headache Is A Rare Disease: Implications For Diagnosis, Treatment And Public Health, Hsiangkuo Yuan, Jan Hoffmann, Elena Ruiz De La Torre, Michael J. Marmura, Mario F. P. Peres

Department of Jefferson Headache Center Papers and Presentations

Cluster headache (CH) is a rare and painful primary headache disorder characterized by severe unilateral pain and cranial autonomic symptoms. This perspective examines the epidemiological evidence supporting the classification of chronic cluster headache (CCH) as a rare disease, noting a prevalence of CH of approximately 124 per 100,000 individuals, with only 3.5-13.7% manifesting CCH. This prevalence meets criteria established by both the US Food and Drug Administration and European Medicines Agency for rare disease designation. The rarity of CCH creates substantial clinical and research challenges, including prolonged diagnostic delays, limited research funding and a dearth of approved treatments. The economic …

Spectacle And The Archipelagic Void: Mark Justiniani, Simulacra, And The Poetics Of Repetition, Luisa L. Gomez

Literary and Cultural Studies Program Faculty Publications

This paper examines the tension between spectacle and meaning in the immersive installations of Filipino artist Mark Justiniani, whose mirror-and-light works produce illusions of infinite regress. While Jean Baudrillard warns against the flattening of meaning in the era of simulacra, I argue that Justiniani repurposes the tools of spectacle to resist simulation. His “void of spectacles” stages not emptiness but layered depth, offering a spatial metaphor for archipelagic thinking—fragmented, entangled, and relational. I read Justiniani’s recursive visual structures alongside the poetics of repetition in the Filipino language, where reduplicated forms such as alaala (memory), guniguni (phantasm), bulong-bulong (rumor), or halakhak …

A Game Of Chicken: Exploring Religiosity, Gambling, And Acts Of Worship In Ren Galeno's Graphic Novel Sa Wala (Nothing To Lose), Elisha Camille Catimpo

Literary and Cultural Studies Program Faculty Publications

There are few more devout than a gambler. By his nature, he believes in something bigger than himself—be it faith, chance, luck, fortune, or some other greater power. The Philippine tradition of cockfighting, or sabong, is known for its established position in Philippine culture and the superstitious nature of the sabungero. In his 1977 book In Defense of Cockfighting, Nid Anima even goes as far as to claim that the Philippines is the cockfight Mecca of the world. In spite of the contradictory implications, there is a deep religiosity at work here, which makes the sabong unique in the Southeast …

Loyal By Nature: How Uncertainty Avoidance Shapes Dispositional Brand Loyalty, Khondoker Sayeed Hossain

Theses and Dissertations

Loyal consumers are prized assets for brands, as even minor improvements in customer retention can lead to significant increases in company profits. Most research has examined brand loyalty as a brand-specific concept and explored what brands can do to develop loyal consumers, overlooking the role of individual-level psychological and cultural factors.

This dissertation aims to address this gap by examining brand loyalty as a personality disposition and investigating its relationship with cultural values. Drawing on the extensive body of research linking culture to consumer judgments and decisions, the central hypothesis proposes that cultural values, particularly uncertainty avoidance, systematically influence individuals' …

Acute Exposure Of American Oyster (Crassostrea Virginica) To Selected Antidepressant Drug: Histological, Biochemical, And Immunohistochemical Assessments, Md. Faisal Amin

Theses and Dissertations

The rapid increase in pharmaceutical use has brought significant health benefits to humans. Studies have shown that many pharmaceuticals, such as antidepressants, are often detected in surface waters, groundwater, and even drinking water. These pharmaceuticals in aquatic environments threaten marine life seriously. Marine bivalves are vital source of seafood for people worldwide. In this study, we examined the effects of short-term exposure to fluoxetine, an antidepressant used to treat depression, at low (0.5 μg/L) and high (5 μg/L) doses over a one-week period on American oysters (Crassostrea virginica) under controlled laboratory conditions. Histological analysis revealed atrophy in the gills and …

Heavy metal contamination in water resources presents a significant environmental and public health challenge, with lead a particular concern due to its toxicity and persistence. This study reports the green synthesis of Fe-Ti mixed oxide nanoparticles (NPs) using dextrose as a green source and investigates their effectiveness in lead removal from aqueous solutions. The synthesized NPs were characterized using XRD, FTIR, XPS, SEM-EDS, and BET analysis, revealing an amorphous structure with a high surface area (292.89 m² g¹) and mesoporous characteristics. XPS analysis confirmed the presence of mixed Fe³⁺/Fe²⁺ valence states in a Ti⁴⁺-rich framework, creating diverse binding sites for …

The Effect Of The Markle Mill Dam Removal On The Habitat And Riverine Food Web Of Otter Creek, Jenna Blanton

All-Inclusive List of Electronic Theses and Dissertations

Across the United States, dam removals are increasing in frequency. Despite this, the effects of dam removal on freshwater food webs are under-studied. Most existing studies investigate the impacts on fish assemblages, and very few investigate the impact on diatom, crayfish, and turtle communities. Furthermore, low-head dams are more abundant than large hydropower dams, yet the impacts of their removal are less studied than their larger counterparts. I used a Before After Control Impact (BACI) study design to survey populations of benthic diatoms, riffle-dwelling crayfish, and aquatic turtles. Species richness, species evenness, and Shannon Diversity Index values were used to …

Performance Of The Two Sample Likelihood Ratio Test Under A Nested Dirichlet: A Simulation Study, Edwina Agyeman

Electronic Theses and Dissertations

Compositional data analysis (CoDA) addresses multivariate data constrained to a constant sum, such as proportions or percentages. Originating from early warnings regarding misinterpretation by Pearson (1897), the field was formalized by John Aitchison in 1986, whose foundational work remains highly influential. Over time, new modeling techniques and visualization tools have advanced the field, as noted by Greenacre et al. More recently, Turner et al. proposed an approach based on the Nested Dirichlet Distribution (NDD), which accommodates more flexible dependence structures than the standard Dirichlet model. This thesis builds on the methodology of Turner et al. Chapter 1 introduces the nature …

Evaluating Alpha Spending Functions Applied To Observational Time-To-Event Analysis, Moses Torgbenu

Electronic Theses and Dissertations

This thesis explores the theoretical foundation of the alpha spending approach and extends its application beyond the conventional setting of randomized controlled trials (RCTs) to observational studies with time to event analyses. In these less structured environments, key design parameters such as the total number of events are often unknown, posing challenges for the standard implementation of sequential analysis methods.

Through simulation studies, this research delivers several important contributions. First, it presents a modified approach that uses calendar time to define the timing of interim analyses while relying on event-based information to estimate the correlation among test statistics. This adjustment …

Simultaneous Application Of Multiple Process Control Rules, Tran B. Ngo

Electronic Theses and Dissertations

Statistical Process Control (SPC) charts are tools used in quality control to monitor and analyze the stability of a process over time. This study evaluates the effectiveness of eight individual Western Electric rules, also known as WECO rules, and the various combinations of these rules with Shewhart rule (or WECO rule 1) to SPC charts. As more rules are added to a process control scheme with Rule 1, there is a trade-off: a higher false out-of-control signal rate but an increase in sensitivity, that is the ability of a specified process control scheme to capture a true out-of-control signal. This …

Guided Modes Through The Dual Perspectives Of Geometrical Optics And Wave Equation, Mason Spears

Mathematics and Statistics Undergraduate Departmental Honors Theses

In an optical waveguide, only finitely many electric field intensity profiles travel without loss, and these are aptly named guided modes. This paper uses fundamental concepts from the two paradigms of interpreting light, geometrical and physical optics, to derive guided modes axiomatically. First, basic principles of geometrical optics are demonstrated in a slab waveguide to explain characteristics of optical waveguides such as total internal reflection and numerical aperture. Dispersion curves are assembled from the same principles and used to show that only finitely many guided modes exist for a given waveguide. Next, Maxwell’s equations are used to derive the famous …

A New Approach To Probabilistic County Population Forecasting With An Example Application To West Texas, David Swanson, Jeff Tayman, Mike Cline

Publications, Reports and Presentations

This paper shows how measures of uncertainty can be applied to existing subnational population forecasts using the 107 counties that make up West Texas as a case study. The measures of forecast uncertainty are relatively easy to calculate and meet several important criteria routinely applied by state and local demographers. We also report the results of two independent comparisons supporting the argument that our approach is valid. The paper concludes it is well-suited for developing probabilistic population forecasts in the United States and elsewhere.

Master of Urban and Regional Planning Workshop Projects

Grounded Growth Planning Cooperative partnered with Sabin Community Development Corporation (CDC), a non-profit affordable housing developer in North/Northeast Portland. The project goal was to examine 11 sites in their Scattered Sites Portfolio for the possibility of infill development to increase the portfolio’s financial performance and to provide additional housing to individuals with intellectual and developmental disabilities (IDD). Accessory Dwelling Units (ADUs) were the primary focus of the evaluation, as they can be constructed without modifying the existing housing and displacing existing tenants. The report identifies opportunities for Sabin CDC to take advantage of Portland zoning code changes that allow increased …

Rebounds Reconsidered: Exploring Perceived Causes And Consequences Of People's Beliefs About Rebound Relationships, Hunter Krampe

All-Inclusive List of Electronic Theses and Dissertations

Romantic breakups are common and can significantly impact emotional well-being. Many individuals enter rebound relationships despite the prevailing belief that these relationships are disingenuous or unhealthy. While limited empirical research exists, some studies suggest rebound relationships may have positive effects, contradicting common advice. This study examined perceptions of rebound relationships, assessing whether individuals who entered a new relationship shortly after a breakup (3 weeks) were perceived more negatively than those who waited longer (3 months). Using a 2x2 experimental design, participants rated targets on emotional state, personality traits, and expected relationship stability. Results indicated that rebounders were not perceived as …

The Impact Of Previous Police Contact And Attitudes Toward Police On Firearm Carriage In A College Student Population, Amanda Kroll

All-Inclusive List of Electronic Theses and Dissertations

This study examines whether an association exists between police contact and firearm carriage. Additionally, the present study examines whether the intrusiveness of police contact has an association with firearm carriage. Questionnaires measuring participant demographics, perceptions of the police, contact with the police, and firearm carriage were administered to 222 participants recruited through undergraduate psychology courses at a state university in the Midwest. Results indicated that participants with a history of contact with the police were more likely to carry a firearm than participants with no contact with the police. Regarding frequency of firearm carriage, participants with a history of police …

The Influence Of High Iq On Adhd Symptom Presentation And Outcomes In Children, David A. Lee

All-Inclusive List of Electronic Theses and Dissertations

Research suggests that a high intelligence quotient (IQ) may contribute to the underdiagnosis and misdiagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD) in children. High IQ may allow children to compensate for executive functioning-related deficits inherent in ADHD and/or may influence behaviors such as high activity level or not following rules that mimic ADHD symptoms. To gain a better understanding of the relationship between IQ and ADHD, the present study aimed to investigate how high IQ impacts symptoms of inattention and hyperactivity as well as outcomes related to academic performance, emotional regulation, and peer relationships in children. The study utilized archival data from …
