The Influence Of Sex On Cognitive Control Performance And Frontoparietal Network Integrity In First Episode Psychosis, Kaitlyn Mcfarlane Greer Jun 2022

The Influence Of Sex On Cognitive Control Performance And Frontoparietal Network Integrity In First Episode Psychosis, Kaitlyn Mcfarlane Greer

Theses and Dissertations

Cognitive deficits in first-episode psychosis (FEP) are well documented including deficits in cognitive control, but how sex may influence or impact these cognitive deficits is not well known. Cognitive deficits may impact multiple neural networks, including the fronto-parietal network (FPN). How sex may influence the structural integrity of regions in the FPN is also an important area of research in FEP that may provide further insight into the beginnings of the disease. The current study aimed to examine sexual dimorphisms in structural integrity of the frontoparietal network (FPN) and its role in cognitive control in FEP. A total of 111 …

Predicting Columbian Sharp-Tailed Grouse Lek Occurrence In Grand Teton National Park, Wyoming, Jonathan D. Lautenbach, John A. Stephenson, Jeffrey L. Beck Jun 2022

Predicting Columbian Sharp-Tailed Grouse Lek Occurrence In Grand Teton National Park, Wyoming, Jonathan D. Lautenbach, John A. Stephenson, Jeffrey L. Beck

Western North American Naturalist

Many North American populations of lekking grouse have declined across their ranges, and understanding and evaluating population trajectories can assist in better managing these iconic species. Columbian Sharp-tailed Grouse (Tympanuchus phasianellus columbianus) is a subspecies of Sharp-tailed Grouse that has declined across its range in the Intermountain West over the past century. Management of this species primarily focuses on habitat around leks; therefore, knowing where Columbian Sharp-tailed Grouse leks occur is key to their conservation. We used a resource selection framework to predict lek occurrence in an area with multiple known leks in Carbon County, Wyoming. We used …

Exploring Melatonin As A Treatment For Oral Ulcers, William H. Sutherland Jun 2022

Exploring Melatonin As A Treatment For Oral Ulcers, William H. Sutherland

Undergraduate Honors Theses

The hormone melatonin is best known for its role in the sleep-wake cycle, but its anti-inflammatory and antioxidant effects have significant implications that have not been fully explored in oral health. Some studies use melatonin to treat gastrointestinal ulcers, including duodenal ulcers and oral mucositis, but we found no study reporting its effects on more common oral ulcers, like aphthous stomatitis. We hypothesize that the anti-inflammatory and antioxidant characteristics of melatonin could effectively prevent and heal oral ulcers. In this paper, we review the literature on melatonin to propose its use as a treatment for oral ulcers. We also include …

"Newstead And I Stand Or Fall Together": Memorial Ecology And Multispecies Agency In Byron's Early Poetry, Taylore Ann Wintch Jun 2022

"Newstead And I Stand Or Fall Together": Memorial Ecology And Multispecies Agency In Byron's Early Poetry, Taylore Ann Wintch

Theses and Dissertations

Scholars studying memory, literary tourism, and Byron all note the cooperation between author and audience at work in memorials--be it in terms of speech and response, hospitality and reception, or memory and forgetting. None, however, address the environment at Newstead as an agentic being involved with Byron's memorial legacy. Byron acknowledged multispecies beings as important actors in his eventual legacy. Through some of his early poems, we see the land under and around Newstead Abbey, as well as its nonhuman life, exercising agency and affecting Byron's memory. I limit my analysis to Byron's early poetry partly to trace how a …

Concurrent And Incremental Validity Of Parent- And Teacher-Report And Neuropsychological Measures Of Executive Functions, Attention, And Hyperactivity In An Outpatient Community Mental Health Clinic Pediatric Sample, Lindsay Morgan Fruehauf

Theses and Dissertations

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that affects academic, social, and health functioning. The psychometric properties of measures commonly used in diagnostic settings to assess the constructs of attention, hyperactivity, and executive functioning, including concurrent and incremental validity with other commonly used measures, are not well-established. Additionally, these specific psychometric properties within ecological samples of children and adolescents presenting to community-based clinics is infrequent. The purpose of this dissertation was to describe a sample of children and adolescents presenting to a community-based mental health clinic and to test the concurrent and incremental validity of parent- and teacher-report questionnaires …

Sleep And Eating Behavior Among Adolescent Females With Overweight Or Obesity: The Role Of Appetite-Related Cognitive Processes, Kirandeep Kaur Jun 2022

Sleep And Eating Behavior Among Adolescent Females With Overweight Or Obesity: The Role Of Appetite-Related Cognitive Processes, Kirandeep Kaur

Theses and Dissertations

Insufficient sleep duration and poor sleep quality can potentiate weight gain and obesity in adolescents. Furthermore, overweight and obese females are at unique risk for insufficient sleep and associated health complications. We examined self-reported sleep duration and self-reported adequacy of sleep duration as potential moderators of the relationship between eating behavior and several cognitive processes including hedonic hunger, executive dysfunction, and self-control. We used a multisystemic conceptual framework to highlight the pathways that may explain the relationship between sleep behaviors and the Healthy Eating Index (HEI). The study employed a cross-sectional design. Participants completed baseline measures of height and weight, …

Affective Transfer In Writing: Utilizing Affect In Teaching For Transfer, Emily Morgan Jun 2022

Affective Transfer In Writing: Utilizing Affect In Teaching For Transfer, Emily Morgan

Theses and Dissertations

According to current scholarship in writing studies, students with a positive affect toward writing are more likely to transfer writing knowledge and skills. Yet my findings from an IRB-approved longitudinal study suggest that this is not always the case. This study was designed to see what students transfer from their first-year composition course, focusing especially on rhetoric, process, genre, and mindfulness. In annual semi-structured interviews that took place over the course of three years, two study participants described having positive writing affect but did not discuss transfer, even when prompted. These students express caring much more about a writing task …

The Behavioral And Neurophysiologic Relationships Between Sensory Processing And Autistic Traits In Emerging Adults, Savanah Calton Jun 2022

The Behavioral And Neurophysiologic Relationships Between Sensory Processing And Autistic Traits In Emerging Adults, Savanah Calton

Theses and Dissertations

The majority of individuals diagnosed with Autism Spectrum Disorder (ASD) experience sensory processing difficulties that are also associated with greater presence of autistic traits, psychiatric difficulty, and intolerance of uncertainty (IU). These relationships are also expressed in the neurotypical (NT) population, termed the Broader Autism Phenotype (BAP), and present with impacts to daily functioning/well-being just as prominently. However, little is known concerning the neurophysiologic nature of these behavioral relationships, especially in young adults. Thus, the purpose of the current study was to examine the behavioral and neurophysiologic nature of the relationships between sensory processing, autistic traits, and related behavioral functions …

Auditory Brainstem Response In Autistic Children: Potential Implications For Sensory Processing, Madelyn Cate Jun 2022

Auditory Brainstem Response In Autistic Children: Potential Implications For Sensory Processing, Madelyn Cate

Theses and Dissertations

Autistic people frequently experience sensory processing difficulties. For many on the autism spectrum, such difficulties can significantly impact important functions and quality of life. We are only beginning to understand the neural mechanisms of atypical sensory processing. However, one established way to measure certain levels of auditory processing is with auditory brainstem responses (ABR). While ABR has been primarily hypothesized in the current literature as a means of early detection/diagnosis in autism, additional research is needed to determine the ABR’s utility in examining sensory processing in this population. Thus, we evaluated ABR in 19 young children with autism during various …

Synthesis And Applications Of Α,Β-Dehydroamino Acid-Containing Peptides, Diego A. Moya Jun 2022

Synthesis And Applications Of Α,Β-Dehydroamino Acid-Containing Peptides, Diego A. Moya

Theses and Dissertations

Yaku’amide A (YA) is a linear anticancer peptide that is rich in bulky dehydroamino acids (ΔAAs) and β-hydroxyamino acids (β-OHAAs). In our recent total synthesis of YA, we featured a one-pot anti dehydration–azide reduction–O→N acyl transfer process for the stereospecific construction of Z- and E- ∆Ile residues. Despite previous total syntheses and our efforts, the synthesis of YA remains lengthy. Via computational studies, we identified two analogue peptides that closely resemble the conformation of YA. The use of simpler and symmetrical bulky ΔAAs such as dehydrovaline (ΔVal) and dehydroethylnorvaline (ΔEnv) as surrogates of ∆Ile, along with azlactone chemistry for their …

The Regulation Of Atg9a-Mediated Aggrephagy By An Ulk1-Independent Atg13-Atg101 Complex, Joshua Youngs Jun 2022

The Regulation Of Atg9a-Mediated Aggrephagy By An Ulk1-Independent Atg13-Atg101 Complex, Joshua Youngs

Undergraduate Honors Theses

Aggrephagy, a type of autophagy, is an essential cellular process by which protein aggregates are collected and broken down in the lysosome. Protein aggregates are implicated in several diseases including Alzheimer’s disease, diabetes, and cancer. Here, we investigate the ATG13-ATG101 protein complex, a sub-complex of the canonical ULK1 complex whose regulatory role in aggrephagy is not completely understood. We also develop a protein fragment complementation (PFC) assay using the biotin ligase TurboID to study the functions of the ATG13-ATG101 complex with increased specificity. We demonstrate that ATG13 is required for optimal degradation of p62-ubiquitin condensates. We also show that a …

The Dna Methylation Landscape Of Five Pediatric-Tumor Types, Alyssa C. Parker, Badí I. Quinteros, Stephen Piccolo Jun 2022

The Dna Methylation Landscape Of Five Pediatric-Tumor Types, Alyssa C. Parker, Badí I. Quinteros, Stephen Piccolo

Faculty Publications

Fewer DNA mutations have been identified in pediatric tumors than in adult tumors, suggesting that alternative tumorigenic mechanisms, including aberrant DNA methylation, may play a prominent role. In one epigenetic process of regulating gene expression, methyl groups are attached at the 5-carbon of the cytosine ring, leading to 5-methylcytosine (5mC). In somatic cells, 5mC occurs mostly in CpG islands, which are often within promoter regions. In Wilms tumors and acute myeloid leukemias, increased levels of epigenetic silencing have been associated with worse patient outcomes. However, to date, researchers have studied methylation primarily in adult tumors and for specific genes—but not …

Synthesis Of Yaku’Amide A Analogues And Impact Of Dehydroamino Acids On The Structure And Stability Of Incipient 310 Helical Peptides, Daniel Joaquin Jun 2022

Synthesis Of Yaku’Amide A Analogues And Impact Of Dehydroamino Acids On The Structure And Stability Of Incipient 310 Helical Peptides, Daniel Joaquin

Theses and Dissertations

The first project in this dissertation describes the total synthesis of yaku’amide A analogues. Natural product yaku’amide A possesses potent anticancer activity and exhibits a novel mode of action. However, due to its complex asymmetrical isoleucine dehydroamino acids, the synthesis of this polypeptide poses a unique challenge. Despite the efficient synthesis developed in our lab, the total synthesis of this natural product remains lengthy. In order to simplify the overall synthesis, symmetrical dehydroamino acids were incorporated to replace the dehydroisoleucine residues yielding two analogues of yaku’amide A that closely resembles the conformation of the natural product. Biological testing of the …

Relative Influence Of Precipitation And Grazing On A Salt Desert Shrub Plant Community, Clint A. Stonecipher, Eric Thacker, Michael H. Ralphs

Western North American Naturalist

Long-term vegetation monitoring is essential to understanding plant responses to both climate and grazing. The objective of this study was to monitor the long-term effects of precipitation on vegetation changes within a salt desert shrub plant community and determine whether grazing by livestock altered the vegetation during this time. The study was located within the Colorado Plateau in southern Utah. Two sites were selected. One exclosure was constructed at each site, and foliar cover was measured inside and outside the exclosure to separate the effect of grazing from precipitation on vegetation change over a 30-year period. Shrubs were the dominant …

Monitoring Whitebark Pine Stand Health In The Central Washington Cascades, Nancy H. Parra, Teresa J. Lorenz, Taza D. Schaming, Alison Scoville

Western North American Naturalist

Whitebark pine (Pinus albicaulis) plays a vital role in colonizing newly disturbed areas, providing shade for other tree species to germinate, and supplying food for a variety of birds and mammals, such as Clark’s Nutcrackers (Nucifraga columbiana) and grizzly bears (Ursus arctos horribilis). Decline of whitebark pine populations has been attributed to several factors, including white pine blister rust (Cronartium ribicola), mountain pine beetle (Dendroctonus ponderosae) outbreaks, and fire exclusion. In 2009, the U.S. Forest Service began to install permanent plots in whitebark pine stands in Washington and Oregon as …

Climate Change And The Global Nutrient Overload: The Microbial Response Of Extreme Waterbodies To Environmental Change, Samuel P. Bratsman Jun 2022

Climate Change And The Global Nutrient Overload: The Microbial Response Of Extreme Waterbodies To Environmental Change, Samuel P. Bratsman

Theses and Dissertations

One of the defining characteristics of our current epoch—the Anthropocene—is modification of nutrient cycles. At regional to global scales, humans have fundamentally reshaped the availability of carbon, nitrogen, and phosphorus. These changes are particularly apparent in freshwater ecosystems, which receive surface and groundwater inputs of nutrients from agriculture, fossil fuel use, and wastewater. In this thesis, I investigated how the addition of nutrients affects microbial community and biogeochemistry in two extreme environments: the hypereutrophic shallow Utah Lake and nutrient-limited Arctic permafrost streams. In my first chapter, I used bioassay and dilution bioassay experiments to identify what factors control harmful algal …

Understanding And Working Through Self-Harm, Maya Wilde Jun 2022

Understanding And Working Through Self-Harm, Maya Wilde

Student Works

Self-harm is a coping strategy used by many adolescents dealing with mental disorders. Fifteen articles from academic journals published between 2012 and 2022 were examined. Those who struggle with non-suicidal self-injury (NSSI) experience overactivation in the fronto-limbic system of the brain, which includes the amygdala (Kaess et al., 2021). Self-harm decreases activity and stress in the amygdala and increases the amount of dopamine in the brain (Kaess et al., 2021; Reitz et al., 2015). Self-harm may be used as a way to regulate negative affect. Seeing blood might be a significant part of an episode of NSSI, but it is …

Improvement Of Ex Vivo Testing Methods For Spine Biomechanical Characterization, Aubrie Lisa Taylor Jun 2022

Improvement Of Ex Vivo Testing Methods For Spine Biomechanical Characterization, Aubrie Lisa Taylor

Theses and Dissertations

This dissertation contributed three main areas to flexibility testing and biomechanical characterization of human spinal segments. The first was a literature review of existing testing methodology, the second examined common spine fixation procedures, and the third developed an improved fixation method. Spine biomechanical characterization is the primary technique for assessing the healthy, diseased, and surgically treated response of spinal tissues. However, despite decades of use, no standard testing protocol or reporting methodology for flexibility testing conditions has been established. As part of the present work, a comprehensive, systematic literature review was performed, and the methods sections of 242 relevant journal …

Computational Methods To Simulate Molten Salt Thermophysical Properties, Talmage Porter, Michael M. Vaka, Parker Steenblik, Dennis Della Corte Jun 2022

Computational Methods To Simulate Molten Salt Thermophysical Properties, Talmage Porter, Michael M. Vaka, Parker Steenblik, Dennis Della Corte

Faculty Publications

Molten salts are important thermal conductors used in molten salt reactors and solar applications. To use molten salts safely, accurate knowledge of their thermophysical properties is necessary. However, it is experimentally challenging to measure these properties and a comprehensive evaluation of the full chemical space is unfeasible. Computational methods provide an alternative route to access these properties. Here, we summarize the developments in methods over the last 70 years and cluster them into three relevant eras. We review the main advances and limitations of each era and conclude with an optimistic perspective for the next decade, which will likely be …

Mapping Auditory And Vestibular Response Neurons In The Optic Tectum Of Larval Zebrafish, Erika Marks, Arminda Suli Jun 2022

Mapping Auditory And Vestibular Response Neurons In The Optic Tectum Of Larval Zebrafish, Erika Marks, Arminda Suli

Undergraduate Honors Theses

Cellular mapping of the sensory receptive fields of brain structures is a critical step in understanding function and dysfunction in development. Deficits in the ability to receive, process and integrate the senses leads to difficulties recognizing and responding appropriately to stimuli. To understand how the senses are integrated, it is first necessary to map the neurons receptive to inputs from individual senses. The optic tectum of zebrafish is a structure known for its homology to the superior colliculus of mammals and is a center of multisensory integration – including visual, auditory, and somatosensory stimuli. However, the microcircuitry of this important …
