Characterization Of Ocular Surface Pathology And Tear Film Dysfunction Due To Type 1 And Type 2 Diabetes Mellitus, Judy Weng

Pharmaceutical Sciences (PhD) Dissertations

Untreated diabetes mellitus leads to development of microvascular and macrovascular complications affecting heart, nerves, kidney, and eyes. While the etiological mechanisms of diabetes-associated retinopathy and cataract have been well characterized, the time kinetics and the severity of diabetes-mediated injury to the ocular surface and its various components like tear film, goblet cells and glycocalyx, has not yet been investigated. These pathological changes can potentially cause dry eye and corneal injury including epithelial erosion, impaired wound healing and keratopathy. As the mainstay treatment option for the management of dry eye disease due to diabetes mellitus, artificial tears are frequently used. Therefore, …

The Associations Between Stress, Depression, And Health Complications: A Comparative Study Between Young And Old African American Childbearing Adolescents, Lakyah Morgan

2023 Fall Honors Capstone Projects - Archive

Stress and depression are noted as major psychological determinants impacting health outcomes for childbearing women. African American (AA) women have been shown to experience “wear and tear” or “weathering” over time with increasing complications. Via secondary analysis, the current study explored the association between stress, depression, and maternal and infant health complications and examined a potential trend of “weathering” emerging between younger and older AA childbearing adolescents. The Institutional Review Board (IRB) approved primary study examined birth experiences and mental health of adolescents up to nine months postpartum. The current study noted significant associations between postpartum depression (EPDS scores) and …

Re-Regulating Dietary Supplements, Jessie L. Bekker, Alex Flores, Michael S. Sinha

Journal of Food Law & Policy

In 1994, Congress introduced the Dietary Supplement Health and Education Act (DSHEA) to create a regulatory framework for the dietary supplement industry. Despite the increased market size of dietary supplements, the Food and Drug Administration’s (FDA) pre-market authority to regulate the introduction of dietary supplements into the stream of commerce has remained subdued. Under DSHEA, the FDA has limited authority to review dietary supplements before entering the market. Unlike pharmaceuticals, which must be proven safe and effective prior to approval and marketing, dietary supplements can be sold to consumers without such reassurances. We call on Congress to amend DSHEA to …

Growing Agriculture Literacy’S Presence In America’S Classrooms, Emily Stone

Journal of Food Law & Policy

“Americans, as a whole, were at least two generations removed from the farm and did not understand even the most rudimentary of processes, challenges, and risks that farmers and the agricultural industry worked with and met head-on every day.” This quote perfectly describes the mindset of agriculture stakeholders in 1981 as they began to realize the drastic steps our education system had taken away from using principles of agriculture in K-12 education. As they saw it, Americans were moving out of rural America, away from farms, and becoming less connected to the food they daily consumed. Simultaneously, the education system …

The Contradictory Nature Of U.S. Laws And Nutrition Programs And Their Effects On Infant Feeding, Lily Patel

Journal of Food Law & Policy

The contradictory nature of U.S. laws, including the laws concerning infant feeding, though supposedly aligned with policies to promote wellness in Americans, can exacerbate gender and race inequality and work against the National Strategy. The overarching goal of U.S. laws concerning infant feeding is to ensure that infants are fed, nourished, and receive proper nutrition. However, the laws often appear to be directly contradictory to one another in the priorities they are promoting.

Free For All: Proposing Legislation To Eliminate Food Insecurity In Arkansas Public Schools, A. Mills Bryant

Journal of Food Law & Policy

Schools serve millions of students daily as one of the largest food distribution sites in the United States. However, more than 13.1 million children in the United States, and almost 150,000 in Arkansas, are food insecure. Before the COVID-19 pandemic, most Arkansas schools offered free and reduced lunch to students at or below the poverty line through participation in the National School Lunch Program (“NSLP”). During COVID-19, Congress passed The Families First Coronavirus Response Act (“FFCRA”) and The Coronavirus Aid, Relief, and Economic Security Act (“CARES”) (hereinafter “The Acts”). This legislation effectively eliminated food insecurity in participating American public schools, …

Ethanol Dysregulates Sirt1-Mediated Lipogenic Signaling Pathways Through Α4*-Nicotinic Acetylcholine Receptors In Hepatocytes., Caitlin Christina Wilkerson

Electronic Theses and Dissertations

Alcohol-associated liver disease (ALD) is a broad spectrum of diseases ranging from steatosis to severe hepatic cirrhosis, none of which have any FDA approved therapies. Downregulation of hepatic Sirtuin 1 (Sirt1) activity by ethanol has been shown to lead to an upregulation of the pro-lipogenic gene targets under its jurisdiction, resulting in increased lipogenesis and triglyceride accumulation. It was hypothesized that ethanol acts on α4*-nicotinic acetylcholine receptors (α4*-nAChRs) in hepatocytes to decrease Sirt1 expression, which ultimately dysregulates lipid metabolic homeostasis. Ethanol’s effects were investigated in cultured AML12 hepatocytes and in WT primary mouse hepatocytes acutely exposed to ethanol. Consistent with …

The Interplay Between Lung Adenocarcinoma, Nutrient Availability, And The Microbiome., Alexis A. Vega

Electronic Theses and Dissertations

Lung cancer is one of the most common forms of cancer diagnosed, and has the highest lethality rate across all other forms of cancer in the U.S. While current therapeutic options include chemo-, immuno-, and radio-therapy, the benefits of caloric or nutrient restriction on cancer cells has also been investigated. Due to the many biological functions associated with methionine, many have proposed a methionine restricted diet would lead to favorable outcomes when combating cancer. Although our cells are incapable of synthesizing methionine, the bacteria found in our microbiome can. Furthermore, recent discoveries suggest an independent microbiome found within tumors that …

Genetic Risk Scores For Hypertension And Chronic Kidney Disease In African Americans., Aastha Kakar

Electronic Theses and Dissertations

Hypertension (HT) and chronic kidney diseases (CKD) are complex conditions, disproportionally prevalent among African Americans (AA) and are influenced by multiple genetic as well as environmental factors. Genetic risk scores (GRS) enable the analysis of the combined effects of multiple single nucleotide polymorphisms (SNPs). This study investigates the association of blood pressure (BP) and CKD GRS with BP, hypertension (HT) and CKD; early-onset HT and CKD; and investigates interactions of the GRSs with environmental measures in AA. We observed a significant association between the BP-GRS with HT, SBP and DBP. The odds of HT for one standard deviation (s.d.) increase …

Investigating The Effects Of Subchronic Dietary Zinc Supplementation On Diet-Induced Metabolic Dysfunction-Associated Steatotic Liver Disease., Oluwanifemi Esther Bolatimi

Electronic Theses and Dissertations

Zinc deficiency is associated with metabolic dysfunction-associated steatotic liver disease (MASLD). Previous studies show zinc supplementation improves steatosis, but its therapeutic effects in established MASLD remain unclear. We developed a model to characterize the effects of zinc supplementation on high-fat diet (HFD) induced MASLD and hypothesized established MASLD would be attenuated. Mice were fed control diet or HFD for 12 weeks and then grouped into normal or zinc-supplemented diets for 8 additional weeks. At euthanasia, plasma and liver tissues were collected for phenotypic analysis. Twelve weeks of HFD altered glucose clearance and body composition. Eight weeks of subsequent zinc supplementation …

The Impact Of Environmental Pollutants On Alcohol-Associated Liver Disease Pathogenesis., Tyler Charles Gripshover

Electronic Theses and Dissertations

Steatotic liver disease is brought upon by differing etiologies and its global prevalence is expected to keep increasing over the next several decades. Particularly, alcohol-associated liver disease (ALD) manifests from excessive alcohol consumption where the liver retains lipids and progresses with metabolic dysfunction. Previous studies have demonstrated that environmental pollutants, polychlorinated biphenyls (PCBs) promote metabolic dysfunction associated steatotic liver disease (MASLD), in diet-induced obesity models. However, it is unknown if environmental pollutants may also promote ALD pathogenesis. Thus, this dissertation focuses on characterizing the effects of PCB126 in a rodent ALD model followed by multiple ‘Omics approaches to identify mechanisms …

Environmental Exposures And Male Reproductive Outcomes., Damilola Rukayat Owoade

Electronic Theses and Dissertations

Male sexual dysfunction comprises various conditions, including erectile dysfunction (ED) and ejaculatory dysfunction. Testosterone deficiency (TD), which has been linked to some of these sexual dysfunctions, is characterized by low production of testosterone by the testes. These male reproductive outcomes may develop due to exposure to various risk factors, including environmental exposures. These environmental exposures may include volatile organic compounds (VOCs) and tear gas. This dissertation aims to examine the effects of tear gas exposure and VOCs on male reproductive outcomes. The association between tear gas exposure and male reproductive outcomes was assessed using data obtained from an online anonymous …

Investigation Of Heterocyclic Amines And N-Acetyltransferase 2 Genetic Polymorphism In The Dysregulation Of Hepatic Energy Homeostasis: A Gene-Environment Approach., Kennedy M Walls

Electronic Theses and Dissertations

Heterocyclic amines (HCAs) are mutagens generated when cooking meat for prolonged periods of time or until well-done. Recent epidemiological studies reported significant associations between dietary HCA exposure and insulin resistance and type II diabetes. However, no previous studies have examined if HCAs, independent of meat consumption, contributes to pathogenesis of insulin resistance or metabolic disease. It is well known that HCAs require hepatic bioactivation by cytochrome P450 1A2 (CYP1A2) and N-acetyltransferase 2 (NAT2). NAT2 expresses a well-defined genetic polymorphism in humans that, depending on the combination of NAT2 alleles, correlate to rapid, intermediate, or slow acetylator phenotypes that exhibit differential …

Bayesian Strategies For Propensity Score Estimation In Causal Inference., Uthpala I. Wanigasekara

Electronic Theses and Dissertations

Causal inference is a method used in various fields to draw causal conclusions based on data. It involves using assumptions, study designs, and estimation strategies to minimize the impact of confounding variables. Propensity scores are used to estimate outcome effects, through matching methods, stratification, weighting methods, and the Covariate Balancing Propensity Score method. However, they can be sensitive to estimation techniques and can lead to unstable findings. Researchers have proposed integrating weighing with regression adjustment in parametric models to improve causal inference validity. The first project focuses on Bayesian joint and two-stage methods for propensity score analysis. Propensity score modeling …

Causal Inference For The Effect Of Continuous Treatment On Time-To-Event Outcomes And Mediation Analysis On Health Disparities In Observational Studies., Triparna Poddar

Electronic Theses and Dissertations

The dissertation comprises two projects related to causal inference based on observational data. In healthcare research, where abundant observational data such as claims data and electronic records are available, researchers often aim to study the treatment effect and the pathway of that effect. However, estimating treatment effects in observational data presents challenges due to confounding factors. The first project focuses on estimating continuous treatment effects for survival outcomes, while the second concentrates on mediation analysis, allowing the exploration of the pathway of the causal effect. Both projects involve addressing confounding variables. In the first project, I investigate estimation of the …

The Radical Power Of Education, Arindam Nandi, Nicole Haberland, Thoai Ngo

Gender, Education, Justice, and Equity (GEJE)

When education works, people thrive and societies flourish alongside economies. We have made real progress on primary enrollment on the global scale, with 90% of children enrolling in school. However, completion rates lag far behind—only 77% of children complete lower secondary school and 58% complete upper secondary. Those numbers decline sharply for those living in poverty, for girls, and for Indigenous communities, with 44% of adolescent girls in low- and middle-income countries (LMICs) either dropping out of primary school or never attending at all.

Low educational attainment and illiteracy exclude children from the freedoms that come with learning and also …

Effects Of Dietary Rumen-Protected Choline Supplementation To Periparturient Dairy Cattle On Inflammation, Metabolism, And Performance During An Intramammary Lipopolysaccharide Challenge, Turner H. Swartz, Barry Bradford, Laman Mamedova, Kari Estes

Dairy Science and Food Science Faculty Publications: 2022 to Present

Recent studies have suggested that dietary rumen-protected choline (RPC) supplementation can modulate immune function, attenuate inflammation, and improve performance in periparturient dairy cattle; however, this has yet to be evaluated during a mastitis challenge. Therefore, the objective of this study was to examine the effects of supplementation and dose of RPC on metabolism, inflammation, and performance during an intramammary lipopolysaccharide (LPS) challenge. Parous Holstein cows (parity, mean ± SD, 1.9 ± 1.1 at enrollment) were blocked by calving month and randomly assigned within block to receive either 45 g/d of RPC (20.4 g/d of choline ions; CHOL45, n = 18), …

The Chemical And Physical Analysis Of Hiveless Tm A Plant Based Honey Alternative, Javin Goodine

All Theses

Honey is perhaps the oldest and one of the world's most widely used natural sweeteners. It is a viscous, sweet, golden substance bees produce via natural enzymatic and physical modification of flower nectar. It has long been prized for its unique flavor and medicinal properties. It can be incorporated into many applications, such as bread, cured meats, alcohol, condiments, candy, pharmaceuticals, and skin care products. In 2022 alone, America consumed over 600 million pounds of honey (Board Reports, 2023), but less than a fifth of that was produced domestically, the rest imported from other countries. The international honey trade can …

Enabling Breeding For Fruitlet Freeze Tolerance In Peach, Ufuk Caglar

All Theses

Climate change is affecting the production of temperate fruit crops, with cold temperatures emerging as a critical abiotic stressor that limits plant growth and performance. Freeze damage, particularly in spring, has resulted in significant economic losses in peach production in the southeastern United States. Research efforts in peach and other Prunus species have primarily focused on studying dormancy-related traits associated with bloom time, such as chill and heat requirement, with fruitlet freeze tolerance not equally represented. Breeding for climate resilience in peach requires a combination of these traits to allow for late bloom via targeted chill requirement and high heat …
