The Effects Of Psychological Stress On Gut Health In Mice Fed Either A Healthy Diet Or The Total Western Diet, David Keenan Thomas Prescott

All Graduate Theses and Dissertations, Fall 2023 to Present

The Total Western Diet (TWD), a rodent diet designed to model the typical American dietary pattern, has been shown to worsen inflammation and colitis severity in mice. Psychological stress has also been associated with increased intestinal inflammation, barrier dysfunction, and alterations to the gut microbiome. The goal of this study was to determine whether combining the TWD with psychological stress would further worsen colitis severity and alter the gut microbiome. To investigate this, mice were fed either a healthy control diet or the TWD and exposed to psychological stress using a social disruption stress model. Colitis was induced using established …

Additionally, by applying the principles of SCT, the curriculum incorporates scenario-based questions, opportunities to engage with peers, …

Independent And Combined Effects Of Early-Life Iron Deficiency And Antibiotic Exposure On Growth And Hematological Outcomes In A Piglet Model, Ginger M. Fitzpatrick

Master's Theses

Iron deficiency (ID) affects over 2 billion individuals globally. Children under 5 are at increased risk of ID due to rapid growth and are especially vulnerable to its negative consequences because of iron’s essential role in cognitive development and immune maturation. ID is the leading cause of iron deficiency anemia (IDA), with IDA affecting approximately 40% of children in this age group. Antibiotic (abx) exposure is also prevalent during early life and may disrupt growth and through gut dysbiosis, with increasing use posing additional risk in younger populations. Geographically, there is overlap in regions with high anemia prevalence and those …

Food-Form Delivery Of Spore-Forming Probiotics As An Alternative To Gavage In Animal Models, Aubreyona Faith Migliori Skalka

All Graduate Theses and Dissertations, Fall 2023 to Present

Western dietary patterns are characterized by nutrient-poor, calorie-rich diets and have been linked to poor health outcomes and gut inflammation phenotypes. Probiotics are often taken to support gut health, but many beneficial bacteria do not survive transport through the digestive system to produce any effect. Spore-forming bacteria, such as Bacillus coagulans, are more resilient due to their hardy outer coat which aids in survival through many obstacles encountered in the gastrointestinal tract, including acidic stomach conditions. In research studies, probiotics are usually given to mice through a procedure called oral gavage, where a tube is used to deliver the …

Impact Of Inhibiting Mitochondrial Calcium Uptake On Calcium Homeostasis And Postmortem Metabolism In Porcine Muscle, Fatema Rahaman Mishu

All Graduate Theses and Dissertations, Fall 2023 to Present

After harvesting the animal, pork muscle continues to undergo changes as it turns from muscle into meat. During this early period, the muscle uses up energy and produces acid, which lowers pH and can affect important quality traits such as color and how well the meat holds water. A key driver of these early changes is calcium, a natural mineral inside muscle cells that helps control contraction and energy use. In this study, we tested whether mitochondria (the cell’s “powerhouse”) help control calcium after harvest and, in turn, influence early postmortem changes in pork. We used a research compound (DS16570511) …

A Functional Nutrition Literature Review For Brain Fog And Adhd-Like Symptoms In Adults, Natalie Elisani Aldahondo-Matos

Department of Nutrition Student Projects

Attention-deficit/hyperactivity disorder (ADHD) and ADHD-like symptoms, such as difficulty concentrating, mental fatigue, and problems with executive functioning, are increasingly recognized in adults. Although medication is commonly used to manage ADHD, there is growing interest in whether nutrition may also play a role in supporting brain function and attention. Several nutrients involved in brain health including omega-3 fatty acids, vitamin B12, magnesium, iron, and choline  have been suggested as potential contributors to cognitive performance and attention. However, the research examining the connection between diet and ADHD symptoms is still limited and sometimes shows mixed results.

The purpose of this project was …

Ethnicity, Culture, And The Epidemiology Of Eating Disorders, Rebecca Atwell

Honors Theses

This systematic literature review addresses the research question: How does culture affect eating disorders? It examines the role of ethnicity and culture in shaping the prevalence, symptom presentation, and treatment of eating disorders across diverse populations. Although eating disorders have traditionally been studied in Western, predominantly White populations, growing evidence suggests that cultural norms, ethnic identity, globalization, and exposure to Western ideals significantly influence both the development and expression of disordered eating behaviors. Twenty peer-reviewed studies published between 2000 and 2024 were included. These studies were identified through systematic searches of PubMed, Scopus, Web of Science, and PsycINFO and selected …

The Effect Of Low And High-Carbohydrate Diets On Memory Performance In College Students, Samia Baugh, Zoe Zajko, Jamie Analuisa, Ivanna Jacome

Department of Nutrition Student Projects

Carbohydrates are the primary source of energy for the brain and play an important role in processes related to memory performance. The purpose of this study is to examine the impact of a low-carbohydrate diet compared to a high-carbohydrate diet on memory performance in college students aged 18–22 years. For the purposes of this study, a low-carbohydrate diet is defined as a diet providing fewer than 130 grams of carbohydrates per day, while a high-carbohydrate diet provides approximately 325 grams of carbohydrates. This population is particularly important to study because college students experience high academic demands that require strong memory …

Weaning Drives Microbiome-Mediated Epigenetic Regulation To Shape Immune Memory In Mice, Li Yang, Robert C Peery, Shirui Zhou, Xiaomin Chen, Leah M Farmer, Fabiola Gutierrez, Stephanie Fowler, Lanjing Zhang, Julia M Salamat, Karen Riggins, Jiejun Shi, Lanlan Shen

Children’s Nutrition Research Center Staff Publications

During weaning, the transition to solid food diversifies the gut microbiome, triggering a programmed immune response critical for long-lasting mucosal immunity. Previous work showed that the gut microbiome mediates epigenetic development in intestinal stem cells (ISCs) during suckling, but what happens during weaning is unclear. Here, genome-wide profiling revealed that weaning-driven microbiome changes shape the DNA methylome and transcriptome of murine ISCs in an IFNγ-dependent manner. Specifically, we observe demethylation of enhancer elements essential for MHC class II genes, which results in a transcriptional memory that persists through differentiation into adulthood. IFNγ blockade, or low-dose penicillin to target Gram-positive bacteria, …

We experienced a 45-year-old male with ADPKD who developed spontaneous retroperitoneal hemorrhages with hypertension in the right subcapsular renal space without trauma. After his condition worsened with conservative management, he was treated by renal transarterial embolization (TAE). Over the next eight years, he experienced bilateral bleeding at three different sites and underwent repeated endovascular treatment with renal TAE to stop the bleeding. After the fourth occurrence, the patient underwent hemodialysis. Although renal cysts and urinary tract bleeding occur frequently in ADPKD, retroperitoneal hemorrhage is rare; however, TAE is both effective and a good way to preserve renal function.
