Flood Risk Reduction: An Analysis Of Policy, Policy Implementation, And The Role Of Non-Governmental Organisations, Elsa Cutler

Nepal: Geoscience in the Himalaya

As global temperatures rise, flood frequency and severity increase due to unpredictable rainfall, consequently escalating flood risk for Nepal's population. Therefore, implementing mitigation strategies and disaster risk reduction operations has become of utmost importance to effectively protect the people of Nepal. In 2024, countless lives were lost and a great deal of infrastructure was destroyed in Kathmandu due to the floods that swept through the city. The scale of damage the flood caused could have been minimized if the risk management policies in place were enforced properly. This investigation uses interviews, news reports, policies, policy analyses, and the case study …

To Pause With A Cliffhanger Or A Temporary Closure? The Differential Impact Of Serial Versus Episodic Narratives On Children's Physical Activity Behaviors, Amy Shirong Lu, Melanie C Green, Caio Victor Sousa, Jungyun Hwang, I-Min Lee, Debbe Thompson, Tom Baranowski

Children’s Nutrition Research Center Staff Publications

Research has supported the effectiveness of narratives for promoting health behavior, but different narrative presentation formats (serial vs. episodic) have seldom been compared. Suspense theories suggest that serial narratives, which do not provide a full resolution at the end of an episode, may create higher motivation for continued engagement with a story. Forty-four 8 to 12-year-old children were randomly assigned to watch an animation series designed for an existing active video game in which the plot was delivered either continuously across multiple episodes (serial) or in multiple yet relatively independent self-contained episodes (episodic). Controlling for social desirability, children who watched …

Children’s Nutrition Research Center Staff Publications

Background: Assessing fruit and vegetable intake is important to determine the effectiveness of nutrition intervention studies. Few objective measures of fruit and vegetable intake have been directly compared within the same study participants.

Objectives: This study aims to compare the relative validity of 2 different skin spectrophotometry devices to serve as biomarkers of plasma carotenoid concentrations, self-reported fruit and vegetable intake (FVI), and carotenoid intake, to examine if both devices can be used to approximate FVI.

Methods: Human skin carotenoid scores (SCS, Veggie Meter-assessed) and color space measurement data from 2 prior studies were used. Participants' skin color space parameters …

Investigating The Role Of Metallothioneins In Fungal Iron Homeostasis, David Eap

Theses and Dissertations

The pathogenic fungi Aspergillus fumigatus requires metals to survive and infect humans, but metal overload can be detrimental. Metallothioneins (MTs) are small, cysteine-rich proteins that alleviate metal toxicity by binding excess metals (typically Zn or Cu) for storage or delivery. A recent report indicates that the Fe-S cluster binding glutaredoxin GrxD and the putative Cu-MT CmtA were interacting under high iron conditions in A. fumigatus. We hypothesize that this MT may have a role in binding iron or Fe-S clusters under iron overload conditions to prevent iron toxicity. We also aim to characterize this new MT by determining its …

Circannual And Kinship Cues Shape Reproduction And Epigenetic Aging In Peromyscus, Kim Tuyen Huynh Dam

Theses and Dissertations

Evolutionary success is defined by the ability of a species to adapt and survive across many generations. This success is not determined by any single attribute but rather includes the entrenched, complex system that could be associated with biological rhythms, reproductive strategies, and regulations of epigenetic and genetic components. By using closed Peromyscus colonies as a model and by coupling mathematical modeling, analyses of breeding records, epigenetic studies, and in vitro and in vivo experiments, this dissertation aims to discover how Peromyscus adjusts to the internal and external pressures to ensure their survival and preserve evolutionary fitness in controlled environments. …

Exploring The Ancestry And Mutational Signatures Of Free-Breeding Dogs From Chernobyl And The Galápagos Islands, Gabriella Jean Spatola

Theses and Dissertations

Two free-breeding dog populations, one in Chernobyl, Ukraine, and the other on the Galápagos Islands, Ecuador, exist on opposite sides of the globe, yet both hold unique scientific potential to further our understanding of free-breeding dog population dynamics and evolutionary processes related to their environments. In the following studies, blood samples from more than 400 individual Chernobyl dogs were collected and their genomes were analyzed alongside over 1500 purebred and 200 global free-breeding dogs, describing genetic relationships and the extent of admixture with purebred migrants. Importantly, the sampled Chernobyl dogs had long-term exposures to ionizing radiation because of the 1986 …

Hybrid Penstemon Flowers: Colors, Pigments, And Detectability & Experimental Teaching: Evaluating The Impact Of Active Learning, Josh Thomas Edward Stevens

Theses and Dissertations

Shifts to different primary pollinators are often accompanied by changes in suites of floral traits. Understanding how and why these floral adaptations evolve is a central goal in evolutionary biology. Within the genus Penstemon, the transition from bee-pollinated to hummingbird-pollinated flowers is a common evolutionary pattern. These pollinator shifts have caused several closely related species to exhibit distinct pollination syndromes. One example of this evolutionary phenomenon can be seen within the sister species P. eatonii (hummingbird-pollinated) and P. laevis (bee-pollinated). These two species form several hybrid zones, in which hybrid individuals exhibit colors resembling both parental species, along with a …

Investigating The Immunomodulatory Effects Of Cdk8/19 Inhibitor Senexin631 In A Her2-Positive Breast Cancer Model, Stephen O'Rourke

Theses and Dissertations

HER2-positive (HER2⁺) breast cancer is aggressive and often develops resistance to anti-HER2 therapies. CDK8 and CDK19, transcription-associated cyclin-dependent kinases (tCDKs) in the Mediator complex, are dysregulated in HER2⁺ breast cancer, correlate with poor survival, and support transcriptional escape driving therapeutic resistance. Previous studies Previous studies in immune-deficient models demonstrated that CDK8/19 inhibition (CDK8/19i) reduces pro-tumor macrophages (M2Φs), but its role in immune-competent tumors and innate immune–mediated tumor control remains unclear. Since HER2⁺ tumors are often immunogenic and anti-HER2 therapies rely on innate immune activation, reprogramming immunosuppressive M2Φ toward an M1Φ-like phenotype could enhance antitumor immunity. We hypothesized that CDK8/19i modulates …

Novel Approaches To Combat Neuro-Degradation: Investigations Of Two Supplemental Strategies Aimed At Improving Warfighter Performance, Blaine Lints

Theses and Dissertations

This dissertation examines the efficacy of two distinct nutritional supplementation strategies for improving physical and/or cognitive performance under stress. The first study investigated the effects of 150 mg caffeine plus 150 mg theacrine ingestion in tactically trained individuals. Results indicated that the combination of caffeine and theacrine was associated with significant improvements in reaction time, accuracy, and measures of ocular control following high-intensity interval (HII) exercise. The HII exercise protocol consisted of ten repetitions of 60s high-intensity intervals (≥90% maximal oxygen uptake [VO_2max]) followed by 120s low-intensity intervals (~40% VO_2max) on a treadmill. These benefits were …

Investigating Mechanisms And Day-Level Factors That Influence Children’S 24-Hour Movement Behaviors, Hannah Parker

Theses and Dissertations

Twenty-four hour movement behaviors (i.e., physical activity (PA), screen time (ST), and sleep) are associated with health outcomes, chronic disease (obesity, type 2 diabetes), and mortality. Most literature evaluating children’s 24-hour movement behaviors has focused on static person-level demographic information such as age or biological sex. Relatively less work has examined the variable factors that change day to day, such as environment or context. The Structured Days Hypothesis (SDH) suggests that when children are in structured environments, they have healthier movement behaviors compared to less structured environments where children have more discretionary time to engage in obesogenic behaviors. Besides school/childcare, …

Modeling The Interaction Between Pain And Movement: Insights From Brain Activation Patterns And Context-Dependent Emotion In Chronic Low Back Pain, Pradeep Kumar Sahu

Theses and Dissertations

In persons with chronic pain, fear or anxiety related to movement is a well-established model under the biopsychosocial framework that explains in part, the chronicity of symptoms commonly reported by individuals with chronic low back pain (cLBP). This dissertation aimed to further understand the link between the context-dependent emotion network in the brain and movement in two separate studies using brain functional MRI and autonomic nervous system indices. Aim 1sought to investigate the brain functional connectivity linking brain regions involved in context-dependent emotion and movement while cLBP participants moved their back inside the scanner by performing a modified trunk bridging …

Heat Shock Induces Alternative Polyadenylation Through Dynamic Dna Methylation And Chromatin Looping, Emily E Fink, Yi Zhang, Briana Santo, Anwita Siddavatam, Rosie Ou, Vishal Nanavaty, Byron H Lee, Angela H Ting

Faculty, Staff and Student Publications

Alternative cleavage and polyadenylation (APA) is a gene regulatory mechanism used by cells under stress to upregulate proteostasis-promoting transcripts, but how cells achieve this remains poorly understood. Previously, we elucidated a DNA methylation-regulated APA mechanism, in which gene body DNA methylation enhances distal poly(A) isoform expression by blocking CCCTC-binding factor (CTCF) binding and chromatin loop formation at APA control regions. We hypothesized that DNA methylation-regulated APA is one mechanism cells employ to induce proteostasis-promoting poly(A) isoforms. At the DNAJB6 cochaperone locus, acute heat shock resulted in binding of stress response transcription factors heat shock factor 1, ATF6, and YY1 at …

Renal G Protein-Coupled Estrogen Receptor 1 Regulates The Epithelial Sodium Channel Promoting Natriuresis To A Greater Extent In Females, Victoria L Nasci, Jean C Bopassa, Elena Mironova, Megan Rhoads, Ravneet Singh, Dennis P Buehler, David M Pollock, Oleh M Pochynyuk, James D Stockand, Eman Y Gohar

Faculty, Staff and Student Publications

Hypertension prevalence is lower in women than men. Enhanced renal sodium (Na+) handling in females has been implicated in sex-differences in hypertension. Epithelial Na+ channel (ENaC) is a key contributor to Na+ homeostasis and is regulated by estrogen. Recent evidence suggests G protein-coupled estrogen receptor 1 (GPER1) evokes a female-specific natriuresis that involves endothelin-1 (ET-1). ET-1 has been shown to downregulate ENaC activity, but whether GPER1 regulates ENaC to modulate natriuresis is unknown. We tested the hypothesis that renal GPER1 functionally interacts with ENaC to promote natriuresis in a sex-specific manner. RNAscope confirmed co-expression of GPER1 and ENaC in rat …

Faculty, Staff and Student Publications

Smooth muscle cell-specific myosin heavy chain, encoded by MYH11, is selectively expressed in smooth muscle cells (SMCs). Pathogenic variants in MYH11 predispose to a number of disorders, including heritable thoracic aortic disease associated with patent ductus arteriosus, visceral myopathy, and megacystis-microcolon-intestinal hypoperistalsis syndrome. Rare variants of uncertain significance occur throughout the gene, including MYH11 p.Glu1892Asp, and we sought to determine if this variant causes thoracic aortic disease in mice. Genomic editing was used to generate Myh11E1892D/E1892D mice. Wild-type (WT) and mutant mice underwent cardiovascular phenotyping with and without transverse aortic constriction (TAC). Myh11E1892D/E1892D and WT mice displayed …

Children’s Nutrition Research Center Staff Publications

The current-day epidemic of type 2 diabetes, largely driven by increased adiposity and reduced physical activity in the setting of genetic susceptibility, is a major public health challenge. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) presciently proposed the Diabetes Prevention Program (DPP), a multicenter randomized clinical trial, designed by investigators in conjunction with NIDDK staff and initiated in 1996. The primary goal of DPP was to determine whether an intensive lifestyle intervention (ILS) or metformin in comparison with placebo would reduce the development of diabetes in a high-risk population with prediabetes. After mean 2.8 years, ILS …

The Effects Of Extreme Weather On Rural Transportation Infrastructure And Crop Prices Along The Lower Mississippi River, James Mitchell, Hunter D. Biram

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Extreme weather events are worsening the fragile rural infrastructure in the United States, impacting trade flows of agricultural products. The Mississippi River, vital for transporting agricultural commodities, reached historic lows during the 2022 and 2023 fall harvests, increasing transportation costs and lowering crop prices. This paper estimates the cost of these drought events by analyzing Arkansas soybean basis data and Mississippi River stream gauge data. Low river levels significantly weaken soybean prices, with the impact being a function of a grain market's distance to a river port. Findings have implications for public policy investment in rural infrastructure and risk management …

Targeting Cdk2 And Other Novel Cell Cycle Targets For Breast Cancer Therapy, Mei-Kuang Chen, Linjie Luo, Nicole Massoumi, Khandan Keyomarsi

Faculty, Staff and Student Publications

Introduction: The dysregulation of cyclin-dependent kinases (CDKs) is a key driver of cancer progression, making them attractive therapeutic targets. In CDK4/6 inhibitor (CDK4/6i)-resistant breast cancer, targeting CDK2 offers a promising approach. CDK2 is frequently hyperactivated due to cyclin E1 overexpression or retinoblastoma protein loss, acting as a mechanism that sustains proliferation despite CDK4/6 inhibition. CDK2 inhibitors (CDK2i) show strong anti-tumor activity, particularly in combination with CDK4/6i or immune checkpoint inhibitors.

Areas covered: This review explores the biological roles of CDK2 and its regulatory mechanisms. The review highlights the latest advancements in CDK2i, their mechanisms of action, and their potential in …
