Understanding Wellbeing In Refugee Youth From The African Great Lakes Region., Victory Osezua
Electronic Theses and Dissertations
Young refugees are a vital and growing population in the United States that experience health inequities that make them vulnerable to adverse health outcomes. The health inequities that are evident between refugees and the general population elucidate the disparate power relations between the outcomes of the colonial past and postcolonial present. Although research shows that colonialism and their more recent experience of racism may have adverse long-term impacts on young people's health, it is essential to understand the contexts that shape their wellbeing. While the westernized model of wellbeing focuses on the individual, this study prioritizes the prevention of illness …
An Analysis Of Taste Neuron Morphological Variability: Influences Of Neuron Type And Plasticity., Lisa Christina Ohman
An Analysis Of Taste Neuron Morphological Variability: Influences Of Neuron Type And Plasticity., Lisa Christina Ohman
Electronic Theses and Dissertations
Taste neurons are functionally and molecularly diverse, but their morphological diversity was, until recently, completely unexplored. Taste neurons were considered relay cells, communicating information from taste-transducing cells to the brain without variation in morphology. Instead, individual taste neurons are tremendously morphologically variable. To determine how differences in branching relate to the number and types of taste-transducing cells providing neuronal input, I combined sparse cell genetic labeling with a whole-mount immunohistochemistry and analysis workflow. I found that the maximum number of taste-transducing cells capable of providing convergent input onto individual gustatory neurons varied with a range of 1-22 taste-transducing cells. Consistently, …

How Do Cover Crops Change Soil Health In A No-Till System?, Aysha Kirsten Tapp Ross
Electronic Theses and Dissertations
Nutrient levels and aggregation measurements are currently the most accurate means to measure soil health. It has been suggested that bacterial and fungal communities may prove to be a more accurate measure of soil health. In this study soil microbe communities and nutrient levels were compared in rye cover cropped soils to measure for differences between treatments. Effects between the microbial communities and environmental measurements were also measured within those treatments to test for correlations between soil health measures and microbial communities. The plots were put in a biennial corn (Zea mays L.) and soybean (Glycine max …

Of 698 hospitalized patients, there were 204 (29%) defined to have either depression or anxiety. There were 109 deaths, and of those, 52 (48%) were diagnosed with depression/anxiety. Multivariable logistic regression and Cox proportional hazards models were used to examine associations. ICU admission and ventilation were not significantly associated with depression/anxiety. Depression/anxiety was associated with mortality (OR: 1.84, …
Investigation Of Mitochondrial Inheritance In The Smut Fungus Sporisorium Reilianum., Hector Eduardo Mendoza
Investigation Of Mitochondrial Inheritance In The Smut Fungus Sporisorium Reilianum., Hector Eduardo Mendoza
Electronic Theses and Dissertations
An important goal in evolutionary biology is to address the origin of Earth’s immense biodiversity through the evolution of complex sexual reproduction mechanisms in eukaryotes. Inheritance of mitochondria during sexual reproduction has received special attention in recent years, as these organelles cannot be synthesized de novo and must be transmitted from parent to offspring. The importance of these organelles far exceeds its common function as the energy-producing “powerhouse” of the cell, as it has been found to also be involved in fundamental processes like apoptosis, aging and metabolic homeostasis. Thus, appropriate inheritance of mitochondria is essential for growth and development …
Computational Modeling Of 3d-Printed Lactobacillus-Antibiotic Scaffolds For Bacterial Vaginosis., Veeresh P. Rai
Computational Modeling Of 3d-Printed Lactobacillus-Antibiotic Scaffolds For Bacterial Vaginosis., Veeresh P. Rai
Electronic Theses and Dissertations
The standard treatment for bacterial vaginosis (BV) is currently antibiotics, such as metronidazole, clindamycin, or tinidazole. These antibiotics are highly effective in getting rid of bacteria in the female reproductive tract (FRT); however, there are some bacteria that provide benefits to the FRT which also get expunged. While there are many strains of bacteria that play a beneficial role in the FRT, lactobacilli are among the most important. These bacteria are responsible for maintaining a healthy environment in the FRT via pH regulation by lactic acid metabolism. Antibiotics eliminate all bacteria from an environment, including lactobacilli, and as a result, …

Trained Immunity Enhances The Immune Response And Maintains Microbiome Diversity In Aging And Sepsis, P. Spencer Gill
Electronic Theses and Dissertations
The global population is rapidly aging. It is estimated that over the next thirty years, the number of individuals >60 years of age will increase by over a billion, and the number of individuals over age 80 may increase by 300 million. As humans age, our immune system becomes progressively weaker through a process called immune senescence. This age-related decrease in immune function increases susceptibility to infection and chronic diseases. Sepsis is a leading cause of death worldwide. Over the past two decades, there has been an increased incidence of sepsis which is due, in part, to our aging population …

Electronic Theses and Dissertations
Perfluoroalkyl Substances (PFAS) are a family of man-made, surfactant-like compounds that are a major environmental contaminant. A multitude of studies have indicated that PFAS are able to induce fatty liver disease and modulate lipid metabolism. However, the distinct mechanism of PFAS influence on the liver and metabolism disruption remains to be elucidated. On the other hand, it is well documented that alcohol consumption has various adverse health impacts including fatty liver disease and subsequent progression to more adverse liver states. To date, there are no published studies on whether PFAS and alcohol can jointly exacerbate fatty liver progression or interact …
Concurrent Reporting Of Adverse Childhood Experiences Among Perspectives Of Adolescents And Caregivers., Katie J. Berghuis
Concurrent Reporting Of Adverse Childhood Experiences Among Perspectives Of Adolescents And Caregivers., Katie J. Berghuis
Electronic Theses and Dissertations
The consequences of Adverse Childhood Experience (ACE) events in youth have predominantly been studied through retrospective studies that assess adults’ first 18 years of life or caregiver report of ACEs in youth. Reliance on only caregiver report to discern ACEs is a limitation amongst prior studies as research has found that caregivers tend to underestimate ACEs among their children, and there is even a greater discrepancy of reporting between caregivers and youth 12 years and older. Therefore, this study investigated concurrent reporting of self-report ACE scores in adolescents – defined in this study as 12 to 20 years old – …

The Influence Of Incubation Conditions On Oxygen Consumption During The Development Of Pantherophis Guttatus, Celeste Gallardo
Electronic Theses and Dissertations
The flexible shell of some oviparous reptiles has led to differences in nutrient mobilization and water relations when compared to their rigid-shelled counterparts. Flexible-shelled eggs gain more water during development, and because of the shell structure, yolk calcium content is higher than that of eggshells. When water availability is altered for reptiles with flexible-shelled eggs, differences in both energy and nutrient utilization are observed. This study was designed to determine the baseline metabolic rate during development for the snake, Pantherophis guttatus under normal conditions, and to observe how changes in eggshell calcium and water availability impact embryonic oxygen consumption. Eggshell …
