Exploring The Connection: Field Ecology Research And Student Wellbeing, Elizabeth Small

Graduate Research Theses & Dissertations

Field work is essential in ecological research, offering the opportunity to gather firsthand data, observe natural processes, and deepen our understanding of ecosystems. In my study on small mammal trophic niche dynamics, I investigate how small mammals—critical players in grassland food webs—adapt their diets in response to environmental disturbances. By examining the drivers of variation in trophic niche among three common small mammal species, I aim to uncover how these animals coexist despite similar dietary requirements. Understanding these dynamics is critical for informing global conservation efforts, especially as we work to reverse the biodiversity crisis and restore damaged ecosystems.However, the …

Through The Lens Of Tiktok: A New Perspective To Improving Food And Nutrition Literacy In Adolescents, Devin Kathleen Ebeling-Hammond

Graduate Research Theses & Dissertations

Understanding food, nutrition, and physical activity is essential for everyone, and is important to learn from a young age to foster healthy, lifelong habits. Research indicates that 50% of adolescents do not consume the right amount of fruit, vegetables, or protein, and often consume excessive amounts of fats and sugar. Coincidentally, type 2 diabetes and other non-communicable diseases are on the rise, which can be improved through modifiable health determinants. The purpose of this study is to provide insight into innovative ways to teach adolescents about food, nutrition, and the importance of physical activity. An exploratory pilot study was selected …

Examining Project Flex: A Sport-Based Prison Program For Incarcerated Youth, Gabrielle Bennett

Graduate Research Theses & Dissertations

There is a growing global body of literature examining the experiences of adolescents in sport-based youth development programs. Conversely, the advantages of such programming are often contingent on intention, design, population, and environment. One often overlooked setting that serves a vital population benefiting from the integration of sport-based youth development programs, is juvenile justice facilities. Beyond adolescents, much literature remains to be explored in penal settings, particularly, the inception of sport-based prison programs that utilize an evidence-based curriculum and explicit approach to foster life skill development.

Dna Methylation In Aging And Alzheimer's Disease, Raymond Cheng, Jingmin Shu, Hai Chen, Ming Li, Xiaodong Cheng, Li Liu

The Brown Foundation: Institute of Molecular Medicine

DNA methylation undergoes significant changes with age. These alterations play a pivotal role in the development of age-related diseases, including Alzheimer's disease (AD). Recent advancements in DNA methylome profiling have revealed global hypomethylation patterns, particularly within repetitive elements, as well as gene-specific changes that are associated with neurodegeneration. Age-related alterations in DNA methylation have been implicated in the disruption of key cellular processes, such as inflammation and proteostasis, both central to AD pathology. However, several challenges persist in this field. One major issue is the inconsistency of findings across different brain regions and tissue types, which complicates result interpretation. Furthermore, …

Benthic And Epibenthic Invertebrate Assemblages Associated With Estuarine Submerged Aquatic Vegetation Differ Between Native And Invasive Plants, Marissa Hall, Kathryn O'Shaughnessy, Bethany Kiley, Ashley Mcdonald, Taber Faurie, Zoey Hendrickson, Anna Reimer, Samantha Smith, Charles Martin

Gulf and Caribbean Research

Estuarine submerged aquatic vegetation (SAV) provides vital habitat for macroinvertebrate communities that support diverse food webs and subsequent ecosystem services. Invasive SAV, however, has the potential to alter estuarine food webs through competition with native SAV, resulting in different associated biological communities. In the Mobile-Tensaw Delta (Alabama, USA), the invasive Eurasian milfoil, Myriophyllum spicatum, is fast becoming the dominant SAV, out-competing native SAV such as wild celery, Vallisneria americana. This study investigated the above- and belowground macroinvertebrate assemblages associated with these SAV habitats. We found significantly different assemblages between the SAV, with V. americana supporting more even and …

Slow Glycolysis Exercise Responses On The Body When Fueled By Short-Term Differing Carbohydrate Levels, Skylar Gayman

High Impact Practices Student Showcase Fall 2024

Dieting fads have been a fascination across America for many years. “Have you tried the keto diet?” “What about a low carb diet?” But what many people may not know, or consider, is the physiological effects that these may have on the body. Dieting faddists often find themselves in “bad moods” or “irritable”, lacking the energy necessary to maintain physical activity. Weight loss, although necessary for borderline obese and obese populations, has become a hyper fixation of our population. Often leading us to find “quick fixes” to the very simple, yet well-disciplined answer of a healthy diet and exercise to …

Fisher-hunter-gatherer societies of the Pacific Northwest have depended heavily on seasonal salmon runs as a primary staple for foodstuffs and winter storage essentials. Determining which salmonid species were chosen provides a better understanding of ancient socio-economic strategies that impact food procurement and varying preferences of food items that can lead to resource access limitations. Ultimately, this thesis is a preliminary research project to establish the groundwork for successfully …

Understanding Disparities In Hypertension Treatment Cascade And Validating Blood Pressure Measurement Among Persons Living With Or At Risk For Hiv, Jessica Blair

All ETDs from UAB

In the United States, 44% of adult women >18 years have hypertension. Although non-Hispanic Black adults were more likely to be aware of and treated for hypertension compared to non-Hispanic White adults, Black individuals had the highest prevalence of uncontrolled hypertension. Persons living with HIV have a higher prevalence of hypertension, which is a major modifiable risk factor for cardiovascular disease. Similar to the geographic distribution of hypertension in the US, people living in the South have higher incidence of both hypertension and HIV diagnoses compared to other US regions. Furthermore, accurate diagnosis of hypertension and initiation of treatment is …

Exploring The Epitranscriptomic Response To Senolytics And Senomorphs In Cellular Models Of Aging, Emily Benson

Electronic Theses & Dissertations (2024 - present)

In senescence that occurs with aging, cells stop dividing and initiate a pro-inflammatory program called the senescence associated secretory phenotype (SASP). SASP can lead to cell damage and has been linked to age-related conditions such as cancer, diabetes, osteoporosis, cardiovascular disease, Alzheimer’s disease, and osteoarthritis. The epitranscriptome regulates translation through post-transcriptional RNA modifications and can control when and how much of protein synthesis occurs. Several tRNA modifications that include 5-methoxycarbonylmethyl (mcm⁵U), 5-methoxycarbonylmethyl-2-thiouridine (mcm⁵s²U), and mcm⁵Um (5-methoxycarbonylmethyl-2′-O-methyluridine) are linked to the translation of enzymes involved in the detoxification of reactive oxygen species (ROS), …

Evaluation Of Dietary Fiber Technologies In Sow Diets, Garrin Shipman

Electronic Theses and Dissertations

Various technologies and alternative ingredients are being developed to increase the nutrient value of fibrous feedstuffs, improve animal performance, and promote sustainable swine production. Fiber-degrading enzymes have been extensively studied in growing pigs, with few studies focused on gestating sows. When considering gestating sows have greater energy digestibility of fibrous feedstuffs than grower pigs, the efficacy of fiber-degrading enzymes needs to be determined for implementation in commercial sow diets. As fiber inclusion in gestation diets benefits sow performance, corn dried distiller grains with solubles (DDGS) are a candidate fiber source for gestation alternative energy ingredient. Functional fibers, such as yeast …

Using Focus Groups To Explore Older Black Men's Perception Of Dietary Interventions., Ashley R Shaw, Eric D Vidoni, Mickeal N Key, Brandon A Yates, Roland Thorpe

Faculty, Staff and Student Publications

Older Black men are underrepresented in research despite being disproportionately affected by Alzheimer’s disease (AD) and cardiovascular (CV) risk factors related to AD compared with non-Hispanic Whites. Although dietary interventions have shown promise to reduce modifiable CV risk factors related to AD, Black Americans have lower adherence likely due to lack of cultural considerations. Using a noninterventional convergent parallel mixed-methods approach, this study examined the cultural contexts that inform perceptions of dietary interventions among older Midwestern Black men. All participants completed an online demographic and dietary habit survey prior to focus group discussions. Two focus group discussion sessions were conducted …

BACKGROUND: Older cancer survivors likely experience physical function limitations due to cancer and its treatments, leading to disability and early mortality. Existing studies have focused on factors associated with surgical complications and mortality risk rather than factors associated with the development of poor disability status (DS), a proxy measure of poor performance status, in cancer survivors. We aimed to identify factors associated with the development of poor DS among older survivors of colorectal cancer (CRC) and compare poor DS rates to an age-sex-matched, non-cancer cohort.

METHODS: This retrospective cohort study utilized administrative data from the Texas Cancer Registry Medicare-linked database. …

Faculty, Staff and Student Publications

Background: Birth defects and preterm birth co-occur, with some overlapping risk factors. Many birth defects and preterm births tend to have a male preponderance. We explored potential risk factors impacting sex and preterm (< 37 weeks of gestation) birth differences among infants with selected birth defects delivered from 1997 to 2011 using data from the National Birth Defects Prevention Study (NBDPS).

Methods: The NBDPS was a large multisite, population-based case-control study. Using random forests, we identified important predictors of male preterm, female preterm, and male term, each compared with female term births for each birth defect. Using logistic regression, we estimated odds ratios for associations between important predictors and sex-preterm birth status by birth defect.

Results: We examined 11,379 infants with nine specific birth defects. The top …
