Deficiency Of Rdh10 Causes Cleft Secondary Palate In Mouse., Swetha Raja

Electronic Theses and Dissertations

The focus of this project is to understand the role of Retinoic Acid (RA) produced by RDH10-mediated metabolism of Vitamin A in palate development. For 80 years now, we have known that dietary restriction of RA/Vitamin A can cause cleft palate but we have failed to understand how RA deficiency causes cleft palate. Our gap in knowledge about how RA deficiency causes cleft palate is mainly owing to the fact that we lack a model system to study such defects. The aim of this thesis research project was to determine if conditional inactivation of the Vitamin A metabolic gene Rdh10 …

Regulation Of Haplid Phenotypes In Ustilago Maydis By Ammonium Transporters And Components Of The B Mating Locus., Rena Margaret Wallen

Electronic Theses and Dissertations

Fungi that can switch from budding to a filamentous infectious state have evolved mating type loci. Ustilago maydis, the maize pathogen, must mate with compatible partners possessing different alleles at two mating type loci for successful host infection. The a locus encodes pheromones and receptors, while the b locus encodes subunits of a heterodimeric transcription factor that regulates expression of virulence genes. Mating is triggered by environmental signals, including nutrient deprivation. My goal was to determine the fate of nitrogen starved haploid cells without a compatible mating partner. On solid low ammonium media, wild-type U. maydis filaments. I examined …

Novel Insight Into The Liver-Lung Axis In Alcohol-Enhanced Acute Lung Injury., Lauren G. Poole

Electronic Theses and Dissertations

Background. Individuals who chronically abuse alcohol are almost 4 times more likely to develop Acute Respiratory Distress Syndrome (ARDS), the most severe form of Acute Lung Injury (ALI), but the mechanisms by which alcohol abuse sensitizes the lung to injury are poorly understood. However, the lung appears to share many parallel mechanisms of injury with the liver- a primary target of alcohol abuse. The overarching goal of this dissertation was therefore to expand on established mechanisms of alcohol-induced liver injury to ask innovative questions about mechanisms of alcohol-enhanced acute lung injury, as well as to develop new tools that may …

The Role Of Hif-1Α In Intestinal Epithelial Barrier Function In Alcoholic Liver Disease., Tuo Shao

Electronic Theses and Dissertations

Hypoxia inducible factor 1 α (HIF1α) is an oxygen-responsive subunit. HIF-1α plays a pivotal role in many pathophysiological processes. In addition to oxygen availability, HIF-1α can be regulated by multiple other factors in response to various pathophysiological processes. Previous studies showed that hepatic HIF-1α could be beneficial or harmful in experimental alcoholic liver disease (ALD). However, the role of intestinal HIF-1α in ALD has not yet been studied. Given the critical role of the gut-liver axis in ALD, it is important to elucidate the role of intestinal epithelial HIF-1α in ALD. In the first chapter, we used wide type (WT) …

Characterization Of Filifactor Alocis And Its Immune Evasion Strategies Employed Against Human Neutrophils., Cortney Linn Armstrong

Electronic Theses and Dissertations

Periodontal disease is among the most common of inflammatory conditions and is caused by bacterial and host derived factors. The presence of bacteria drives the recruitment of neutrophils, professional phagocytes, to migrate to specific oral sites where they produce potent antimicrobials to kill their target. However, this inflammation and production of antimicrobials must be strictly regulated to minimize collateral host tissue damage. Human neutrophils recognized the oral pathogen Filifactor alocis through Toll-like receptor (TLR) 2 and upon binding, activated both p38 MAPK and ERK signaling pathways, known to be involved in neutrophil cell migration and degranulation. F. alocis also stimulated …

A Novel Method For Synthesis Of Hydroxytyrosol, Emmanuel Onobun

Electronic Theses and Dissertations

Hydroxytyrosol, 3,4-dihydroxyphenolethanol, a naturally occurring polyphenol most common in olive tree (Olea europaea), is one of the most effective member of the polyphenols family, because of its remarkable antioxidant activity, its ability to inhibit oxidation of low density lipids (LDL), and its protection against DNA oxidative damage. Hydroxytyrosol, which is widely used in cosmetics and food supplements industries, can be purchased as an olive oil extract that contains low concentration of hydroxytyrosol besides other polyphenols. The price and low natural abundance of hydroxytyrosol make alternative synthetic sources very attractive. In this research, a novel method for the synthesis of pure …

Early Childhood Adversity And Chronic Illness: An Examination Of A High Risk- Forensic Inpatient Population, Courtney L. Cook

Electronic Theses and Dissertations

Individuals exposed adverse childhood experiences (ACEs) are at increased risk of developing chronic illnesses in adulthood including heart disease, cancer, diabetes, and chronic pain. A relationship between ACEs and health risk factors contributing to chronic disease such as smoking, obesity, and sedentary lifestyle has also been established in prior literature. There is evidence that higher that individuals in forensic inpatient mental health samples are disproportionally exposed to ACEs, which may increase odds of chronic disease development. Despite this evidence, little research has examined the prevalence of ACEs and relationships between ACEs and chronic health conditions and risky health behaviors in …
