Fermentation Of Prebiotics In Whole Food Powders By Probiotic Lactic-Acid Producing Bacterial Strains To Identify Synbiotic Combinations, Michaela Brubaker

Undergraduate Honors Capstone Projects

Dietary interventions with probiotic lactic acid bacteria (LAB) and prebiotics, complex dietary fibers that promote LAB growth, may favorably shift the gut microbiome to reduce colorectal cancer risk. Our primary hypothesis was that the LAB strains NCFM Lactobacillus acidophilus and HNO 19 Bifidobacterium lactis would thrive in the presence of agave, green banana, black raspberry, baobab fruit, or pomegranate peel whole food powders by fermenting their oligosaccharide (OS) components into lactic acid end products. LAB strains were cultured in media with no carbohydrate, purified OS, or one of the whole food powders. LAB strains cultured with agave appeared to grow …

Young Germ Cell Depleted Ovaries In Post-Reproductive Mice And Its Effects On Immune Function, Mckenna Walters

Undergraduate Honors Capstone Projects

It has previously been shown that young, cycling ovarian transplantation in aged female mice increased the general health and life span in regard to their post-reproductive health. It has further been hypothesized that this enhancement of health is directly influenced by the ovarian somatic cells. To address this hypothesis, transplants of young germ cell depleted and germ cell containing ovaries were performed on female mice. The purpose of this study is to continue to discern the reproductive influence on aging health, specifically in the area of immunological well-being. Control group mice were separated by age and treatment mice were subsequently …

The purpose of this study is to expand the understanding of female reproductive health on metabolism. Control mice were grouped by age and treatment mice were age-matched. Treatment mice were placed into one of three groups: 1) mice received germ cell-depleted ovaries, 2) mice received germ cell-containing ovaries, and 3) mice …

How Can Occupational Licensing Reforms Improve Access To Dental Care?, Jacob M. Caldwell, Brian Isom

Undergraduate Honors Capstone Projects

Occupational licensing laws have a large effect on the American economy and requirements affect all levels of professional work, from hairdressers and plumbers to doctors and lawyers.Those laws vary by state and exist to protect consumers from asymmetric information problems. Yet a growing body of literature finds that occupational licensing raises costs for consumers without necessarily raising the quality of service.

The dental field is one such sector of employment that commonly is licensed. Oral health is an important indicator of overall individual health and general wellbeing. Unfortunately, consumers lack access to dental care in many parts of the United …

Alternative Futures For Dalton Wells, Mary Oliver

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Visitation to the Moab region has increased significantly in recent years, causing campgrounds near town to be consistently full. The Dalton Wells area, a recreation area off Highway 191 just north of Moab, has become an especially popular place for dispersed camping, as it is free and in close proximity to town. Dalton Wells does not have the infrastructure or management necessary to support the current number of visitors, straining the site’s fragile desert ecosystem. The site also hosts a dinosaur quarry and the foundations of a historic CCC camp. These resources are unmaintained and at risk of pillaging and …

Third, to measure any differences in the number of microaggressions and microaffirmations girls …

Impacts Of Cattle Grazing As A Tool To Control Phragmites Australis In Wetlands On Nitrogen, Phosphorus, And Carbon, Brittany L. Duncan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phragmites australis is a plant that is causing problems in wetlands by outcompeting native plants that provide food and shelter for millions of migratory birds. Currently, managers try to control Phragmites australis by spraying herbicide, burning, and mowing, but these methods are costly, time consuming, and have low levels of success. Adding grazing as a tool to control Phragmites australis provides a cheap and low labor alternative. However, there are many concerns regarding if grazing will cause nutrient loading in our wetlands that will decrease water quality and alter beneficial functions of wetlands.

To better understand the effects of grazing …

Development Of Mouse Models For Respiratory And Neurological Disease Caused By Enterovirus D68 And Evaluation Of Antiviral Therapies, Brett L. Hurst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enterovirus D68 (EV-D68) is a virus that normally causes disease in children. While this virus typically causes a respiratory infection, in 2014, a large outbreak of the virus was associated with patients that had paralysis of the arms or legs. Even though the virus was discovered in 1962, little was known about the life cycle of the virus or its ability to cause disease. An animal model of disease was needed to understand how the virus causes disease and to develop antiviral compounds to target the virus life cycle.

We adapted the virus by serial-passage in lung tissues from mice …

In Vitro Simulation Of Microgravity Induced Muscle Loss Successfully Increases Expression Of Key In Vivo Atrophy Markers, Charles P. Harding

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Muscle loss from lack of activity is a serious issue for immobilized patients on Earth and in human spaceflight, where the low gravity environment prevents normal muscle activity. Simulating muscle loss in cultured cells is an important step in understanding how this condition occurs. This work evaluates different means of simulating muscle loss and selects the one that most closely mimics the cellular responses seen in animals and humans.

To simulate the microgravity environment of spaceflight, mouse skeletal muscle cells were grown in a rotary cell culture system (RCCS). Growing the cells within a natural gelled substrate was compared against …

Landscape Of Stress: Does Drought Prevail Over Anthropogenic Activity In Influencing Cortisol Levels And Fitness In The Pacific Fisher?, Jennifer R. Kordosky

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fishers (Pekania pennanti) are a species of concern in the Sierra Nevada Mountains of California. Cortisol is a glucocorticoid hormone released to mobilize energy in response to stress and has been used as an indication of an individual’s physiological response to its environment. By collecting samples of fisher hair and measuring an individual’s cortisol, we examined the physiological stress response of the animals to human disturbances (housing density, road density, habitat type, and silvicultural treatements) and drought (tree mortality) in their home ranges. Using AICc model selection, we found that levels of tree mortality within a fisher’s home …

The Total Western Diet And Vancomycin Treatment Increase Inflammation-Mediated Colorectal Cancer, Niklas David Joakim Aardema

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Prior work by our research group showed that the total Western diet (TWD), a rodent diet which models the typical American diet, promoted the development of colon tumors when fed to mice. Other researchers previously showed that vancomycin, an antibiotic that changes the gut microbiome composition, causes differential changes in the severity of colon inflammation and CRC. Our goal was to determine the combined effects of feeding the TWD and vancomycin treatment on colitis and CRC, and if these factors interact. We hypothesized that vancomycin treatment would mitigate colitis and CRC in mice fed the TWD. To this end, mice …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Emerging computing architectures such as, neuromorphic computing and third party intellectual property (3PIP) cores, have attracted significant attention in the recent past. Neuromorphic Computing introduces an unorthodox non-von neumann architecture that mimics the abstract behavior of neuron activity of the human brain. They can execute more complex applications, such as image processing, object recognition, more efficiently in terms of performance and energy than the traditional microprocessors. However, focus on the hardware security aspects of the neuromorphic computing at its nascent stage. 3PIP core, on the other hand, have covertly inserted malicious functional behavior that can inflict range of harms at …

Youth Prevention Programs: A Framework For Conducting Mediation Meta-Analyses, Morgan A. Kawamura

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Often for prevention program designs, researchers are interested in understanding the processes through which a program impacts a targeted outcome. Mediation analysis assists in identifying not only how a program influences an outcome, but also which intermediate variables (i.e., mediators) cause the effects between a program and an outcome to occur. Mediation analysis explains why a program works, which is useful for program developers in creating effective prevention and intervention-based programs.

To make use of mediation analysis findings for preventive intervention programs, researchers need a comprehensive understanding of the mediators between various programs and outcomes. However, a comprehensive examination into …

Abnormal growth of blood vessels in the eye during the course of AMD causes damage to the retina, resulting in irreversible blindness. The goal of this research was to determine whether physical pressure on retinal cells can contribute to the increased blood vessel formation. To replicate the tears in the cell layers, a micropatterning method was used as a means of detaching cells from each other. Two new devices were also developed to mimic slow and fast increases in mechanical pressure on cell layers of the eye. After …

The Impact Of Wood Biochar On The Plant Uptake Of Pharmaceuticals And Personal Care Products From Reclaimed Wastewater, Jeffrey Flashinski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reclaimed water (treated water discharged from wastewater treatment plants (WWTPs)) is increasingly used in drier regions for irrigation purposes. This effectively increases the water supply and reduces the amount of WWTP discharge into surface waters but it creates the potential for contaminants in the reclaimed water, such as pharmaceuticals and personal care products (PPCPs), to accumulate in exposed crops. The US Environmental Protection Agency (US EPA) considers PPCPs contaminants of emerging concern due to their near universal presence in the environment and their potential for endocrine disruption. Biochar is gaining attention as a soil amendment and could potentially be used …

Examining Different Patterns Of Children’S Early Dual Language Development And Nonverbal Executive Functioning, Audrey C. Juhasz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children from non-English-speaking homes often lag behind their English speaking peers academically. However, people who speak two languages often have better executive functioning skills than people who speak only one language. Executive functions are neurologically-based skills related to managing oneself to achieve a goal. The relation between bilingualism and executive function may be due to how two languages are processed in the brain. However, it is unclear if more balanced bilinguals experience larger gains in executive function than people who are less balanced.

Children from low-income homes are at a disadvantage as compared to children from homes with higher incomes. …
