Physical Activity, Cardiorespiratory Fitness And All-Cause Mortality, Jorin Dane Larsen Apr 2024

Physical Activity, Cardiorespiratory Fitness And All-Cause Mortality, Jorin Dane Larsen

Theses and Dissertations

Introduction Both elevated levels of physical activity (PA) and high cardiorespiratory fitness (CRF) are associated with a decreased risk of all-cause mortality. The degree to which an individual's PA level and CRF status interact to influence mortality is not currently fully understood. This study investigated whether PA and CRF were independently related to all-cause mortality, and to what degree PA was associated with improved mortality risk in individuals with low CRF. Methods This is a prospective cohort study using health assessments on individuals gathered between 1975 and 2002. Health assessment data were matched with the National Death Registry to assess …

Conservation And Management Of Greater Sage-Grouse In Strawberry Valley: Quantifying Influences On A Traditional Capture Method And Long-Term Trends In Clutch Size, Janae Radke

Theses and Dissertations

The greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern that has undergone serious declines in the last century. The Strawberry Valley sage grouse population in Utah underwent such a decline from an estimated 3,500 sage grouse in the 1930s to 150 sage grouse in the early 2000s. This decline initiated a long-term conservation and monitoring project in Strawberry Valley with the goal of preserving the sage grouse population. As part of this ongoing conservation project, we investigated factors that impact the success of capturing sage grouse using the night-lighting method (Chapter 1). We found that capture success is …


The Role Of Caloric Intake On Achilles Tendon Health In Pre-Professional Ballet Dancers, Annie G. Smedley Apr 2024

The Role Of Caloric Intake On Achilles Tendon Health In Pre-Professional Ballet Dancers, Annie G. Smedley

Theses and Dissertations

Background: Achilles tendinopathy is a common and debilitating condition among female ballet dancers due to the large repetitive loading forces placed on their Achilles tendons during rehearsals and performances. Tendon health problems in females are exacerbated by a lack of understanding about how energy availability influences tendons. Ballet dancers, as aesthetic athletes, are vulnerable to low energy availability and can enter a spectrum disorder, relative energy deficiency in sport, that consists of low energy availability (with or without disordered eating), menstrual cycle dysfunction, and low bone mineral density (BMD). Aims: 1) To investigate the relationship between insufficient caloric intake and …

Exploring Mesolimbic Circuitry Modulation By Opiates, Interleukin-10, And Psychostimulants, Joakim W. Ronström

Theses and Dissertations

The mesolimbic dopamine (DA) system originates in the ventral tegmental area (VTA) and projects to the nucleus accumbens (NAc) and other areas including the basolateral amygdala (BLA), prefrontal cortex, and the hippocampus. Drug use induces reward and leads to dysregulation in these brain areas and eventually to substance use disorders (SUDs). Chapter 1 introduces the mesolimbic DA system and its relationship to drug use and their relevance to each chapter. Chapter 2 explores opioid effects on BLA circuitry which is known to play a role in the emotional response including anxiety and stress in SUDs. We showed that morphine induced …


Characterization Of Cellular Metabolism Regulation By The Transcription Factor Centromere Binding Factor 1 (Cbf1), Spencer Ellsworth Apr 2024

Characterization Of Cellular Metabolism Regulation By The Transcription Factor Centromere Binding Factor 1 (Cbf1), Spencer Ellsworth

Theses and Dissertations

Centromere binding factor 1 (Cbf1) is a transcription factor that controls the transcription of many genes involved in cellular respiration and lipid biogenesis and, as such, has been associated with hypolipidemia in humans. It is a known substrate for PAS kinase, which phosphorylates Cbf1 and alters its activity. Our hypothesis is that this phosphorylation affects the genes it regulates and the DNA motifs it binds to, perhaps due to different transcription complexes being formed. In this study, we conduct a chromatin immunoprecipitation in Saccharomyces cerevisiae to determine what genes and DNA motifs Cbf1 binds to in its wild type versus …

Theses and Dissertations

The protein Ataxin-2 is a known positive regulator of stress granules in humans, mice and yeast (known as yeast PBP1). Due to the role that stress granules play in diseases including Amyotrophic Lateral Sclerosis (ALS) and cancer, this thesis investigates the role of Ataxin-2 and its protein binding partners in stress granule development and its effects on various metabolic phenotypes of the cell. PAS kinase is a sensory protein kinase, conserved from yeast to man, which regulates respiration and lipid biosynthesis. Our lab discovered that PAS kinase phosphorylates and activates Ataxin-2 in yeast, and that PAS kinase overexpression enhances localization …


Use Of Microcalorimetry To Evaluate Hardening Reactions In Protein Bars During Accelerated Storage, Tiffany Rose Spackman Dec 2023

Use Of Microcalorimetry To Evaluate Hardening Reactions In Protein Bars During Accelerated Storage, Tiffany Rose Spackman

Theses and Dissertations

Protein bars have become a popular option among consumers to increase protein content in their diets. Since there is a large market for protein bars, many factors must be considered when creating a protein bar that both satisfies consumers and has a long shelf-life. Hardening and textural changes in protein bars are some of the most common modes of shelf-life failure in this product category. When the typical product creation timeline from formulation to launch can be as short as 3-6 months and with added pressure from executives to quickly launch another new product afterwards, product development scientists simply do …

Rage In Chronic Pulmonary Inflammation And Obstetric Complications, Katrina Lynn Curtis Nov 2023

Rage In Chronic Pulmonary Inflammation And Obstetric Complications, Katrina Lynn Curtis

Theses and Dissertations

The receptor for advanced glycation end-products (RAGE) is a transmembrane cell surface protein of the immunoglobulin superfamily that acts as part of both the innate and adaptive immune system. RAGE is highly expressed in lung tissue and is therefore of interest in the pulmonary immune response. Specifically, RAGE mediates several cell-signaling responses such as inflammation and apoptosis. This work sought to elucidate the role of RAGE in the setting of chronic pulmonary irritation such as that found in long-term exposure to secondhand smoke (SHS). This irritation has several shared characteristics with lung diseases such as chronic obstructive pulmonary disease (COPD) …

Elucidating The Architecture Of The Tclijn Complex That Converts Cysteine To Thiazoles In The Biosynthesis Of Micrococcin, Diana G. Calvopina Chavez

Theses and Dissertations

Thiopeptides are a family of antimicrobial peptides that are characterized for having sulfur-containing heterocycles, and for being highly post-translationally modified. Numerous thiopeptides have been identified; almost all of which inhibit protein synthesis in gram-positive bacteria. These intrinsic antimicrobial properties make thiopeptides promising candidates for the development of new antibiotics. The antimicrobial peptide micrococcin is a thiopeptide that is synthesized by the ribosome and undergoes several post-translational modifications (PTMs). Micrococcin is formed from a precursor peptide, TclE. TclE comprises an N-terminal leader (35-AA) that is crucial for recognition of the PTM machinery, alongside a C-terminal core sequence (14-AA) that undergoes multiple …

Manipulating And Assaying Chromatin Architecture Around Enhancer Elements In Vivo, John Lawrence Carter

Theses and Dissertations

There are about 20,000 genes in the human genome. The lowly nematode worm, C. elegans, has about the same number of genes. How could two organisms that are so different arise from a similar number of genes? The answer is epigenetics, or the factors that help control when and where genes are expressed. There are many layers that comprise the epigenetic control of genes. One of which is the structure or architecture of chromatin. Chromatin is a complex of DNA and proteins. Histone proteins with DNA wrapped around them form the fundamental component of chromatin, the nucleosome. Chromatin exists in …

Cell Of Origin Identification Using Methylation Signatures From Seminal Cell-Free Dna And Heterogenous Cellular Mixtures, Ryan Barney

Theses and Dissertations

Infertility is an issue for approximately 12% of couples attempting to have a child. Of this group, 50% of the cases are due to male factor infertility. There are many reasons for decreased fecundity in men, but there remains 10% to 15% of infertile men that are diagnosed with the most severe form of infertility, non-obstructive azoospermia (NOA). A diagnosis of NOA implies the lack of sperm cells in the ejaculate with no physiological reason. The current diagnostic test and treatment consist of microscopic examination of seminal fluid and a biopsy to extract any viable sperm from the testis. This …

"The Trees Act Not As Individuals"--Learning To See The Whole Picture In Biology Education And Remote Sensing Research, Rebeka A.F. Greenall

Theses and Dissertations

To increase equity and inclusion for underserved and excluded Indigenous students, we must make efforts to mitigate the unique barriers they face. As their knowledge systems have been historically excluded and erased in Western science, we begin by reviewing the literature on the inclusion of Traditional Ecological Knowledge (TEK) in biology education and describe best practices. Next, to better understand how Native Hawaiian and other Pacific Islander (NHPI) students integrate into the scientific community, we used Social Influence Theory as a framework to measure NHPI student science identity, self-efficacy, alignment with science values, and belonging. We also investigated how students …


Exploring The Role Of Salt-Tolerant Halomonas Inoculant In Altering Plant Gene Expression To Improve Salt Tolerance In Alfalfa., Ashley Kay Miller Aug 2023

Exploring The Role Of Salt-Tolerant Halomonas Inoculant In Altering Plant Gene Expression To Improve Salt Tolerance In Alfalfa., Ashley Kay Miller

Theses and Dissertations

Soil salinity is an increasing problem facing agriculture in many parts of the world. Climate change and irrigation practices have led to decreased yields of large areas of farmland due to increased salt levels in the soil. Irrigation introduces salts to the soil that with time accumulate and threaten crop yield. In arid climates like Utah, the practice of irrigation is especially threatening to salt-sensitive crops including alfalfa (Medicago sativa). Plants that have tolerance to salt are needed to feed livestock and the world's population. One approach to address this problem is to introduce genes encoding salt tolerance into the …

The brain is one of the most energetically demanding organs within the human body and is cognitively susceptible to energetic deficits such that the rise in obesity, insulin resistance, and Alzheimer’s disease in recent decades pose a substantial threat to cognitive longevity. The therapeutic efficacy of ketones are well-established in epilepsy and are currently being applied to other disease states. Alzheimer’s disease is characterized by impairments in brain glucose uptake and metabolism in regions relevant to learning, memory, and cognition that progress with the disease. While brain glucose uptake is impaired, ketone uptake is unaltered, potentially enabling ketones to fuel …


Does Chronic Low Back Pain Influence Breathing Mechanics And Diaphragm Positioning? A Pilot Study, Lindsey Wensel Jun 2023

Does Chronic Low Back Pain Influence Breathing Mechanics And Diaphragm Positioning? A Pilot Study, Lindsey Wensel

Theses and Dissertations

Background and objective: Chronic low back pain (CLBP) is a complex musculoskeletal condition and often the source of the pain is not clear. A correlation has been found to exist between incidences of low back pain (LBP) and those with respiratory diseases such as COPD. This could give reason to believe that the sequence of events could be reversed, and LBP could elicit changes in respiratory function. The purpose of this study is to investigate if CLBP has an influence on breathing mechanics and the positioning of the diaphragm in the trunk. Methods: Volunteers were recruited between the ages of …

Variability Among Individual Male Runners Influences Cumulative Loading More Than Foot Strike Type, Tamarie Trotter

Theses and Dissertations

Foot strike type affects running mechanics and may influence overuse injury occurrence. Measuring the interaction between cumulative load and foot strike type may provide additional information that could eventually help with understanding injury mechanisms. The purpose of this study was to determine how foot strike type affects cumulative loading in runners, and to determine if individual metrics change throughout a 5-kilometer sub-maximal run. 30 participants ran on an instrumented treadmill for 5 km at 3.15 m/s with their preferred foot strike type (14 rearfoot strike, 16 non-rearfoot strike). Stride rate, foot strike angle, loading rate, per stride and per km …


Improving Restoration Success Of Winterfat: Influences Of Hydrophobic Seed Coatings And Planting Depth On Seedling Emergence, Kyle Andrew Cook Jun 2023

Improving Restoration Success Of Winterfat: Influences Of Hydrophobic Seed Coatings And Planting Depth On Seedling Emergence, Kyle Andrew Cook

Theses and Dissertations

In western North America, winterfat (Krascheninnikovia lanata (Pursh) A. Meeuse & Smit) is a valuable protein-rich subshrub whose restoration has been limited by poor seed flowability and low rates of seedling establishment. Seed flowability can be limited by a dense covering of hairs on winterfat fruits that can cause them to clog in mechanized equipment. Seedling establishment can be limited by premature germination of fall-sown seeds that can cause over-winter seedling mortality from freezing, pathogen attack, and winter drought. Seed coatings may provide a way to overcome both of these barriers to winterfat restoration. Coatings can compress hairs against the …


Assessing The Role Of Hybridization In The Evolution Of Two Common Lineages Of Lichen-Forming Fungi, Rachel Keuler Apr 2023

Assessing The Role Of Hybridization In The Evolution Of Two Common Lineages Of Lichen-Forming Fungi, Rachel Keuler

Theses and Dissertations

Once thought to be an evolutionary dead-end, hybridization is now being detected in genomes across kingdoms, perhaps even playing an integral role in evolution. In chapter 1, I investigated the potential influences of hybridization on the evolution of a group of vagrant, asexual species in the Rhizoplaca melanophthalma species group. I sequenced the mitochondrial and nuclear genomes of 55 specimens and found well-supported nuclear phylogenies of both datasets. There were, however, multiple instances of discordance between the mitochondrial and nuclear trees, which can be caused by hybridization. PhyloNet and ABBA-BABA also detected widespread hybridization among this group. In chapter 2, …


Superabsorbent Polymer Use In Rangeland Restoration, Shannon V. Nelson Apr 2023

Superabsorbent Polymer Use In Rangeland Restoration, Shannon V. Nelson

Theses and Dissertations

Soil moisture deficits often hinder rangeland revegetation efforts. Due to sheer numbers and germination timing, invasive annual species can easily outcompete those of desired seeded species for resources, including water. One way to increase seedling establishment may be to increase the amount of water available to seeded species. Superabsorbent polymers (SAPs) can absorb and release hundreds of times their weight in water and slowly release it. Concentrated SAP bands at or near seedling rooting depth may act as a soil water reservoir for germinating seedlings and increase rangeland seedling establishment. The objective of these studies was to evaluate the effect …


Migration Of Elk (Cervus Canadensis) And Barriers To Movement, Levi Watkins Apr 2023

Migration Of Elk (Cervus Canadensis) And Barriers To Movement, Levi Watkins

Theses and Dissertations

Movement patterns of animals are varied, complex, and can be influenced by environmental and anthropogenic factors. One form of animal movement, migration, is influenced by environmental factors that alter the timing, duration, intensity, and likelihood of migration. Additionally, features of the landscape, both natural and anthropogenic, can alter how animals move through their seasonal and home ranges. Movement patterns can be impeded or prevented by features such as railroads, rivers, and roads. Here we explore characteristics of elk (Cervus canadensis) migration by evaluating the strategies of migration exhibited and the factors that influence migration of elk in central and eastern …


Overcoming Barriers To Native Species Restoration Using Gibberellic Acid And Fungicide Seed Coatings, Amber Jo Johnson Apr 2023

Overcoming Barriers To Native Species Restoration Using Gibberellic Acid And Fungicide Seed Coatings, Amber Jo Johnson

Theses and Dissertations

Many barriers can limit restoration success. In the first chapter of this thesis, the barrier of strong seed dormancy is addressed. While dormancy benefits the species' long-term survival, it can present a challenge within a restoration scenario where rapid establishment is required. Soaking seeds in gibberellic acid (GA3) can overcome dormancy. An easier and potentially more effective method to apply this hormone is to coat seeds with a GA3-impregnated polymer, which provides a slow release of the hormone. Seed dormancy can also be mitigated by creating a favorable microsite with increased soil moisture. We compared the emergence and establishment of …
