The Relationship Of Macronutrient Intake With Growth In Children With Type 1 Diabetes Mellitus, Jessica L. Freeling

Electronic Theses and Dissertations

Child growth, a sensitive metric of overall health, results from the intricate interplay of nature and nurture. While the importance of nutrition in child growth is well established, growth trajectories exhibit substantial individual variability, influenced by sex and age, and often characterized by nonlinear patterns. Inadequate nutrition or disease can hinder growth, with potential for recovery upon proper nutrition or acute disease resolution. However, chronic disease or persistent malnutrition may lead to permanent growth perturbation. Notably, before the advent of insulin, chronic stunting and wasting were hallmarks of Type 1 diabetes mellitus (T1DM), though the specific impacts under modern standard …

Exploring The Physiology Of Clostridioides Difficile: Selenium-Dependent Catabolism Of Host-Derived Nutrients, Michael A. Johnstone

Graduate Thesis and Dissertation 2023-2024

Clostridioides difficile is a bacterial pathogen that causes pseudomembranous colitis and the majority of antibiotic-associated diarrheal cases. Broad-spectrum antibiotic usage disrupts the normal gut microbiota and thereby compromises colonization resistance, the main defense against C. difficile infection. Treatment options are limited to vancomycin, fidaxomicin, and the fecal microbiota transplant. Addressing the scarcity of these therapeutics, we documented two explorations in C. difficile drug discovery: (i) evaluation of antibacterial and toxin-suppressing activity of (+)-puupehenone and similar derivatives, and (ii) clarification of a discrepancy in the hypothesized mechanism of auranofin against C. difficile. A better understanding of how C. difficile colonizes …

The Effects Of Moderate Prenatal Alcohol Exposure On Kappa Opioid Receptor Expression Across Development In Rats, Margaret Agajanov, Kelcie Schatz

Research Days Posters 2024

Fetal Alcohol Spectrum Disorder is an umbrella term that describes the host of symptoms that may result from prenatal alcohol exposure (PAE). The incidence of anxiety disorders in children exposed to moderate PAE (mPAE) is twice that seen in children exposed to low amounts. mPAE animal models demonstrate anxiety-like behaviors reflective of those seen in humans exposed to mPAE. Gestational day 12 (G12) in rats is a period during which the amygdala is undergoing significant development. Past studies suggest that mPAE during G12 is implicated in the anxiety-like behavior observed in rats. The basolateral amygdala is part of the anxiety …
