Seventy-one nutrition and dietetics students completed the survey. Most respondents were female, white, and non-Hispanic. The mean total empathy score was 114.69 (SD=11.09) with a range of 81 to 137. Welch’s t-test did not show significant differences by gender, ethnicity, …

The Registered Dietitian Nutritionist’S Implementation Of Dysphagia Screening In Clinical Practice: A Commentary, Nicole Wiksten, Holly Estes-Doetsch, Laura C. Boucher, Sarah Rusnak, Kristen M. Roberts

Journal of Dietetic Education

Background: The Accreditation Council for Education in Nutrition and Dietetics (ACEND) amended the competencies for the future education model (FEM) in dietetic education to include competency 3.6 stating that the Registered Dietitian Nutritionist (RDN) must be able to "Initiate and conduct bedside swallow screenings". There is no clear process for RDNs to implement dysphagia screening in practice or academia. The aim of this review is to inform clinicians and educators on current literature discussing current RDN and speech language pathology approaches to dysphagia screening and to provide a proposed curriculum for implementation of competency 3.6 in clinical practice and academia.

Disability-Related Educational Content In Nutrition And Dietetic Programs: An Exploratory Study, Wendy Medunick, Allison Gomes, Joachim Sackey, Laura Byham-Gray, Jane Ziegler

Journal of Dietetic Education

Background: Health disparities experienced by people with disabilities (PWD) are partly attributed to inadequate knowledge, training, confidence and competence regarding disabilities among health professionals. While registered dietitian nutritionists (RDNs) are key members of the healthcare team, it is unclear how pre-professional nutrition and dietetics (ND) programs prepare future RDNs to care for PWD. This study examined the status of disability-related education within ND programs in the United States. Methods: A descriptive cross-sectional electronic survey was distributed to 570 directors of accredited ND programs. The survey, which adapted questions from a previously validated instrument and published studies, included questions assessing disability-related …

Assessing And Addressing Cultural Competence And Cultural Humility In Dietetic Education, Zoe Duran, Nicholas Slagel, Lisa Caldwell, Katie Kage

Journal of Dietetic Education

Limited theory-informed, dietetic-specific resources are available to guide the development, evaluation, and refinement of culturally competent (CC) curricula. This pilot study used a mixed-methods, theory-informed approach to evaluate CC integration within an undergraduate dietetics curriculum and examine the applicability of existing CC self-assessment tools for dietetic students. A senior-level undergraduate community nutrition curriculum was evaluated using the Tool for Assessing Cultural Competence Training (TACCT), guided by the Campinha-Bacote Model of Cultural Competence in Healthcare Delivery. James Banks’ Model of Multicultural Curriculum Reform was then applied to refine curricular content and learning activities. In addition, 74 students enrolled in a didactic …

Fraction-Seq: An Integrated Experimental And Computational Workflow For Determining The Localization And Abundance Of Small Non-Coding Rnas In Subcellular Compartments, Siddhartha Shah, Tess Cherlin, Yi Jing, Stepan Nersisyan, Benjamin E. Leiby, Isidore Rigoutsos

Computational Medicine Center Faculty Papers

Small non-coding RNAs (sncRNAs) have garnered considerable attention in recent years, following accumulating evidence of their critical roles in many cellular processes. Among sncRNAs, microRNAs (miRNAs) and their isoforms (isomiRs), tRNA-derived fragments (tRFs), rRNA-derived fragments (rRFs), and Y RNA-derived fragments (yRFs) account for more than 95% of all sncRNAs found in cells. Despite their critical regulatory roles, most sncRNAs remain uncharacterized because their functionalization is a lengthy and challenging undertaking. Knowing an sncRNA's abundance helps prioritize among the various choices, while knowing where it localizes in the cell greatly limits the number and identity of its potential targets and helps …

A Novel Role For The Infralimbic Cortex In Conditioned Fear Responding, Julia R. Mitchell, Samantha Tuberman, Rylin Lubash, Leticia C. N. Takasumi, Emmett Bergeron, Roberto Calitri, Mikaela A. Laine, Maryclare Pikus, Victoria Vance, Leena Ziane, Rebecca M. Shansky

Neuroscience: Faculty Publications

Freezing during Pavlovian fear conditioning is the most commonly used indicator of learned fear in rodents. Although freezing and its neural underpinnings have been widely studied, the field has largely ignored other potential indicators of learned fear. Darting, an escape-like conditioned fear response, occurs more frequently in females and is reliably predicted by a distinct behavioral phenotype: heightened shock response and decreased freezing compared to rodents that do not engage in darting. The experiments in this study sought to expand the field’s understanding of conditioned fear by investigating the neural correlates of conditioned darting, focusing on the infralimbic cortex (IL) …

Staphylococcus Aureus Urease Is Controlled By A Complex Regulatory Network To Promote Dissemination During Cauti, Jana Gomez, Jesus Duran-Ramirez, Maristhela Alvarez, Shane Cristy, Jennifer N Walker

Faculty, Staff and Student Publications

Catheter-associated urinary tract infections (CAUTIs) are one of the most common hospital-associated infections in the United States, accounting for >1 million cases annually. One CAUTI pathogen, Staphylococcus aureus, is commonly found persisting asymptomatically in the bladder of catheterized individuals, increasing these individuals' risk of developing infection. Importantly, S. aureus is not only associated with severe symptoms during CAUTI, including bacteremia and septic shock, but it also produces a common uropathogen-associated virulence factor, urease. Despite its importance, urease has only been well-studied in another uropathogen, Proteus mirabilis. While previous studies identified three S. aureus urease regulators, including CodY, …

Dry After-Ripening Increases Germination Of Critically Imperilled Physaria Thamnophila (Zapata Bladderpod), Christopher A. Gabler, Jerald T. Garrett

School of Earth, Environmental, & Marine Sciences Faculty Publications

Effective endangered plant conservation and recovery require empirical knowledge of seed dormancy release and responses to post-collection handling, yet such information is lacking for many rare taxa. Physaria thamnophila (Zapata bladderpod; Brassicaceae), a critically imperilled (G1) species endemic to southern Texas, USA, is poorly studied, and basic questions regarding seed storage and germination remain unresolved. We evaluated the effects of short-term cool-storage duration (14–180 d), storage temperature (refrigeration vs. freezing), dry after-ripening and maternal plant identity on germination probability and timing in P. thamnophila. Dry after-ripening and increased cool-storage duration consistently increased germination and shortened germination time, whereas storage temperature …

Characterizing Water Source Selection By Pinyon Jays (Gymnorhinus Cyanocephalus) In Utah, Audrey H. Biser, Randy T. Larsen, Samuel B. St. Clair, Steven L. Petersen

Student Works

Pinyon jays (Gymnorhinus cyanocephalus) are corvids native to semiarid ecosystems of the western US. Populations have declined by 84% since 1966, yet no causes have been identified and imminent decisions about federal status make understanding pinyon jay ecology increasingly urgent. As drought conditions intensify, water is becoming scarcer in systems that are already characterized by its limited availability. Therefore, pinyon jay decline is likely influenced by increasing aridity. Jays have been observed drinking from springs and artificial water sources in Utah; however, their relationship to water is poorly understood. Our study aims to characterize pinyon jay water source …

Assessing Gene Expression Changes In The Octocoral Briareum Asbestinum Due To Vibrio Coralliilyticus Exposure, Hailey Poignant

All HCAS Student Capstones, Theses, and Dissertations

Coral reefs are an essential ecosystem home to tons of marine diversity that humans have also  learned to rely on, but they are harmed by climate change and the increasing prevalence of disease. While most studies focus on reef-building coral, octocorals also warrant attention to reveal how they respond to similar stressors. Octocorals share distant ancestry with reef-building corals, so there may be overlap in their immune responses which could provide insight into future restoration projects. To understand how octocorals respond to disease, the octocoral Briareum asbestinum was used as a model to examine gene expression changes caused by the …

Ammonium Phosphate Fertilizers Are A More Effective Phosphorus Source Than Superphosphate For Wheat Grown On Acidic Gravelly Soils, Craig A. Scanlan, Raj Malik, Fien Degryse, Andrew Van Burgel, Mike J. Mclaughlin

Grain and Other Field Crops Research Articles

Selecting the most effective phosphorus (P) fertilizer source is essential for maximizing crop yields. However, there is little information to guide the choice between the widely used soluble granular sources: ammonium phosphates and superphosphates. The aims of this study were to examine whether there are differences in wheat (Triticum aestivum L.) grain yield response to ammonium phosphate and superphosphate fertilizers in field conditions, and if these differences relate to diffusion of P from fertilizer granules. Two field experiments were conducted on acidic gravelly soils in Western Australia where P deficiency occurs to compare wheat growth response to P applied …

Urinary Antimony As A Biomarker For Differentiating Heroin And Brown Mixture Use, Shu-Mei Tsai, Yu-Han Hsiao, Yan-Zin Chang, Sai-Wai Ho

Journal of Food and Drug Analysis

Heroin is classified as a Schedule I controlled substance with severe legal consequences for its use, whereas liquid Brown Mixture (BM) is a legally available and commonly prescribed cough remedy in Taiwan. However, numerous cases of BM ingestion have been misinterpreted as heroin use because BM contains opium tincture, leading to similar urine test results. Owing to the rapid metabolism of heroin, detection of the parent drug and its primary metabolite, 6-acetylmorphine, in urine is difficult; thus, interpretation often relies on morphine concentration and the morphine-to-codeine (M/C) ratio, which can be inconclusive. In our BM analysis, the M/C ratio was …

Changes In Water Quality And Microbiota Over Two Years In Florida Hard Clam (Mercenaria Mercenaria) Hatcheries, Bonnie Getter

Electronic Theses and Dissertations 2020 - Present

This thesis characterized the water quality and bacterial communities in nine hard clam hatcheries over two production years through weekly or biweekly water quality and chemistry monitoring, monthly bacterial plating in the second year of production, and select 16S microbiome sampling at select hatcheries to address production bottlenecks and support the reliable production of high-quality seed for Florida’s growing hard clam aquaculture industry. Logistic regression models showed that water source was distinguished by pH, salinity, alkalinity, and nitrite, whereas geographic location was distinguished by temperature, salinity, nitrate, and calcium; temperature, dissolved oxygen, salinity, and alkalinity distinguished seasons. Vibrio bacteria differed …

Contributions Of Arginine And Nitrosative Stress To Huntington’S Disease Progression, Ian D. Gaudet

Electronic Theses and Dissertations 2020 - Present

Neuroinflammation is a well-established component of Huntington's disease (HD) pathogenesis, yet the intricate molecular mechanisms that govern this process remain a topic of ongoing research and debate. This dissertation elucidates a novel pathway linking arginine metabolism and nitrosative stress to core HD pathology. We found that the arginine transporter SLC7A2 is selectively upregulated in various HD cellular models and patient samples. Our findings reveal that this upregulation drives an overactive inflammatory response, leading to abnormally high inducible nitric oxide synthase (iNOS) induction and subsequent nitric oxide (NO) production, which causes excessive protein nitrosylation and an increase in mitochondrial fragmentation.

Towards The Synthesis Of Dragonamide E And Analogs Thereof, Dante Glover

Chemistry Theses

Leishmaniasis is a disease caused by a parasite spread through the female sand fly. It is categorized as a Neglected Tropical Disease and can cause very severe symptoms, even death, if left untreated. Symptoms include skin lesions that can cause permanent scarring, and mucosal membrane infections that can cause facial deformities. More aggressive forms of leishmaniasis can lead to infections of internal organs like the liver and/or spleen and can lead to death. Drug resistance of these parasites has rendered treatment limited and the side effects of which can be harmful as well.

Scientists looking towards new treatments for tropical …

Non-Enzymatic Hepatic Abhd6 Interacts With Akt-Foxo1 Axis To Regulate Metabolic Health, Guannan Li, Laurence T Maeyens, Jiyuan Yin, Jan-Bernd Funcke, Chanmin Joung, Ruizhen Li, Ziying Xu, Ting Wu, Xin Li, Nisi Jiang, Mbolle Ekane, Maria Paula Lopez, Pengju Cao, Sijia He, Adam B Salmon, S R Murthy Madiraju, Marc Prentki, Juli Bai, James F Nelson, Xianlin Han, Yi Zhu, Shangang Zhao

Children’s Nutrition Research Center Staff Publications

The enzymatic role of ABHD6 in insulin secretion and resistance is well documented. However, its non-enzymatic function, especially its effects on metabolic health, including selective hepatic insulin resistance and metabolic dysfunction-associated steatotic liver disease (MASLD), is poorly understood. To define the role of ABHD6 in liver physiology, we generated liver-specific ABHD6 knockout mice, as well as liver-specific native and enzymatically inactive mutant ABHD6 overexpression mouse models. We demonstrate that non-enzymatic ABHD6 contributes to the regulation of selective hepatic insulin resistance and MASLD progression. Mechanistically, we show that ABHD6 localizes to the nucleus and interacts with Akt/FoxO1 axis to regulate insulin …

Influence Of Transboundary Wildfire Smoke On Fine Particulate Matter Concentrations At South Texas Border Schools, Sai Deepak Pinakana, Kabir Bahadur Shah, Owen Temby, Dawid K. Wladyka, Juan L. Gonzalez, Md Saydur Rahman, Katarzyna Sepielak, Amit U. Raysoni

School of Earth, Environmental, & Marine Sciences Faculty Publications

Exposure to air pollutants in indoor and outdoor school environments poses significant health risks to children due to their heightened vulnerability. Increasing wildfire frequency has intensified transboundary smoke transport, with border communities among the first to experience associated air quality impacts. While the impacts of wildfires on air quality are increasingly recognized through satellite observations and modeling, ground-based observations remain scarce in under-monitored regions. Low-cost air sensors were deployed across schools in the Roma and Rio Grande City areas of Starr County, along the U.S.–Mexico border, for 146-days from November 2023 to April 2024. The raw sensor measurements were corrected …

Flexible Grazing: Evaluating Stocker Cattle As A Drought Management Tool For Utah Livestock Producers?, Ross Israelsen

All Graduate Reports and Creative Projects, Fall 2023 to Present

Drought is a persistent concern in the western United States, often leading to reduced forage production, overgrazing, and economic challenges for livestock producers. This study evaluates the economic feasibility of incorporating stocker cattle as a flexible drought management strategy under varying forage conditions across four Utah grazing locations: Park Valley, Nephi, Vernal, and Beaver. The Rangeland Analysis Platform (RAP) was used to estimate annual forage production and stocking rates from 2001 through 2025. Four stocking-rate scenarios (100%, 75%, 60%, and 50% cow–calf stocking rates) were evaluated using a Net Present Value (NPV) framework to compare the economic performance of traditional …

Formulation And Analysis Of Physiochemical And Sensory Properties Of Ready-To-Mix Whey Protein Phospholipid Concentrate Beverage, Chris Jaquin

All Graduate Theses and Dissertations, Fall 2023 to Present

Whey protein phospholipid concentrate (WPPC) is commonly recovered as a coproduct in filtration process whose aim is to obtain whey protein isolate (WPI) from whey protein concentrate (WPC). Whey protein phospholipid concentrate is high in milk fat globule membrane (MFGM), which has been shown in rodent and human studies to have a variety of physiological benefits, including an increase in exercise capacity. Whey protein phospholipid concentrate is currently considered as an underused dairy coproduct, with most of it either being disposed of or used as animal feed. This research consisted of incorporating WPPC in a protein shake–like beverage at a …

Understanding The Impact Of Environmental Change On Shorebird Abundance And Distribution Across The Intermountain West Over The Past 30 Years, Sharon Montecino

All Graduate Theses and Dissertations, Fall 2023 to Present

Shorebirds have declined worldwide over the past century, mainly due to wetland loss and degradation. Wetlands are sites that are temporarily or permanently flooded and provide critical habitat for shorebirds, especially in arid and semi-arid regions such as the Intermountain West. However, climate change and human water use threaten these wetlands, and how these threats may affect shorebirds in this region remains poorly understood. In the early 1990s, shorebird counts at over 160 wetlands across the Intermountain West provided a broad assessment of shorebird populations in the region. These counts remained the only large-scale surveys until 2022, when the Intermountain …

The Effects Of Psychological Stress On Gut Health In Mice Fed Either A Healthy Diet Or The Total Western Diet, David Keenan Thomas Prescott

All Graduate Theses and Dissertations, Fall 2023 to Present

The Total Western Diet (TWD), a rodent diet designed to model the typical American dietary pattern, has been shown to worsen inflammation and colitis severity in mice. Psychological stress has also been associated with increased intestinal inflammation, barrier dysfunction, and alterations to the gut microbiome. The goal of this study was to determine whether combining the TWD with psychological stress would further worsen colitis severity and alter the gut microbiome. To investigate this, mice were fed either a healthy control diet or the TWD and exposed to psychological stress using a social disruption stress model. Colitis was induced using established …

Nutrient Leaching Under Traditional And Intercropped Cover Crop Fields In Northern Utah, Katherine Hewitt

All Graduate Theses and Dissertations, Fall 2023 to Present

This study examines whether cover crops can be used in Utah and the Intermountain West to improve water quality and reduce contamination due to nutrient leaching from agricultural soils into the groundwater. Cover crops such as grasses, clover, and other seed mixtures can be planted to improve soil health, increasing the soil’s ability to retain water and nutrients, which reduces the amount of nitrate and phosphate fertilizers lost through leaching and contamination. In Utah, short growing seasons and limited irrigation water availability hinder the ability to establish cover crops. By planting the cover crop between the rows (intercropping) when the …
