Sugar Consumption In Aboriginal Children Explored From A Social Practice Perspective, Amy Budrikis, Angela Durey, Dan Mcaullay, Paul Ward, Hanny Calache, Thierry Ng, Roma Winmar, Linda Slack-Smith

Research outputs 2022 to 2026

Australian Aboriginal children have higher sugar intake and are disproportionately affected by sugar-related diseases such as obesity, diabetes and dental caries than non-Aboriginal children. The intention of this paper was to highlight the need for approaches that can capture the complexity of health practices without reducing them to either individual choice or structural determination. We explore sugar consumption in Aboriginal children from a social practice perspective. Here, the unit of analysis is the practice, not the individual, where the elements of a social practice (competence, materials and meanings) are integrated into its performance. We conducted qualitative research using elements of …

We investigated the cross-sectional association between total, animal and plant protein intake with the presence of a multidimensional measure of frailty in older women. Participants included 1380 community-dwelling Australian women, mean (SD) age 75.1 (2.7) years. A validated food frequency questionnaire was used to determine total, plant, and animal protein intake. Frailty was assessed using a frailty index across numerous health domains (scored 0–1, ≥0.25 indicating frailty). Cross-sectional associations were analysed using multivariable-adjusted logistic regression models. In total, 275 (19.9%) women were identified as frail. A non-linear inverse association was observed between higher intakes of total protein and the odds …

Diet, Gut Microbiota, And Intestinal Permeability: Emerging Mechanisms In Hypertension Pathogenesis, Esha Vashisht, Helen Nguyen, Francine Z. Marques, Matthew Snelson

Research outputs 2022 to 2026

Hypertension is a leading contributor to global morbidity and mortality, arising from the interplay of genetic and environmental risk factors together with the dysregulation of multiple physiological systems involved in blood pressure control. Recent advances have established the gut as a central regulator, implicating the intestinal microbiota and barrier integrity in the modulation of blood pressure. Alterations in the gut microbial consortium, along with changes in levels of metabolites produced by the microbiota, have been associated with blood pressure regulation in animal models and human studies. Key microbial metabolites, including short-chain fatty acids, trimethylamine-N-oxide, and bile acids influence endothelial function, …

Assessing Climate-Driven Shifts In Floral Resource Availability For Bees On Barrier Islands In The Southeastern U.S., Hannah Brown

College of Graduate Studies: Theses & Dissertations

Climate change can alter the timing of bee and angiosperm phenology, potentially reshaping the seasonal availability of floral resources for bee species. Although plant-pollinator phenology has been widely studied in temperate systems, less is known about these dynamics in subtropical coastal ecosystems, such as barrier islands in the southeastern United States. In this study, we examined climate-driven changes in bee activity and floral resource availability across 16 barrier-island sites spanning from Florida to Virginia. Using museum bee occurrence records, herbarium-derived flowering phenology models, site-specific floristic inventories, and published bee-plant interaction data, we estimated species-specific bee activity periods and daily floral …

The Depuration Of Microplastic Pollution In Aquacultured Indian River Lagoon Oysters, Lee Nguyen

Honors Undergraduate Theses

Plastics are widely used in consumer goods and industrial manufacturing, and their degradation into microplastics (MP, size < 5 mm) has created an emergent environmental pollutant. Plastics readily enter aquatic environments, where they accumulate additional contaminants and bioaccumulate in organisms. While MP contamination in marine ecosystems is well documented, less is known about MP presence in aquacultured shellfish. Depuration, the process of purging contaminants from shellfish, is conducted in sterile seawater without food, which may cause oyster starvation and death. To date, MP depuration has not been examined in the aquacultured eastern oyster (Crassostrea virginica) in published studies. This study had 3 goals: 1) evaluate the effects of algal feed on oyster survival during depuration, 2) determine the effect of algal feed on depuration effectiveness, and 3) investigate the effect of a ten-day depuration on MP concentration in aquacultured C. virginica soft tissue. MP were quantified in oyster tissues, biodeposits, and in industrial algal feed. Tissues were digested using alkaline solutions, manually examined via microscopy, and analyzed using Fourier-Transform Infrared Spectroscopy (FTIR) to investigate MP polymer …

Microglial Apoe Across Alzheimer’S Disease-Relevant Pathologies, Georgia Nolt

Theses and Dissertations--Physiology

APOE exists as three common alleles (APOE2, APOE3, APOE4) that encode their corresponding protein isoforms (apoE2, apoE3, apoE4). Despite differing by only one or two single-amino acid substitutions, each APOE allele confers a distinct AD risk profile with APOE4 increasing risk by 28% and APOE2 decreasing risk by 14% compared to the most commonly expressed APOE3 allele. While traditionally considered “neutral,” APOE3 still accounts for ~36% of AD cases while APOE4 contributes ~57%, indicating that the majority of AD cases would not occur in the absence of the APOE3 and APOE4 alleles. Microglia, the resident phagocytic immune cells …

Characterizing Gut Microbial Communities And Symbiont-Mediated Detoxification In Herbivorous Insects, Rachel C. Vargas

Biology Dissertations

Insect gut bacteria are vital contributors to host physiology, yet the broader prevalence and fitness implications of symbiont-mediated detoxification remain poorly understood. This thesis investigates these dynamics across three research chapters. Chapter 1 uses 16S rRNA sequencing to characterize how grasshopper gut microbial communities vary across species, dietary breadths, and gastrointestinal segments. Chapter 2 evaluates the detoxification capacity of over 150 bacterial isolates from diverse herbivores against the plant allelochemicals phenethyl isothiocyanate, rutin, and chlorogenic acid to determine if host dietary specialization predicts microbial metabolic ability. Finally, Chapter 3 employs fitness bioassays to test whether inoculating generalist herbivores with detoxifying …

American Elderberry's Next Top Pollinator: Evaluating The Role Of Arthropods In Pollination, Jenny K. Burrow

Theses and Dissertations

This study investigates how Black girls in US independent schools experience Zora Neale Hurston’s, Their Eyes Were Watching God, and Toni Morrison’s Song of Solomon, alongside the larger, traditional literary canon taught within high school English classrooms as texts that can shape their sense of self. In this project, wholeness is defined through a tripartite framework consisting of three interconnected parts: Self (a deepened sense of identity and ways of knowing), Community (experiences of belonging, safety, mentoring, and joy), and Purpose (the development of values, meaning, and a sense of connection both to the community and self). These aspects are …

Do Friendship Features Moderate Associations Between Body-Related (Co)-Rumination And Disordered Eating Behaviors?, Annabel Grace Susanin

Theses and Dissertations

For young adults, the transition to college includes increased responsibility and academic pressures, as well as new living environments with same-age peers. The demands of this transition can contribute to increased stress and uncertainty in students, resulting in engagement of behaviors that negatively impact physical and mental well-being. Among these behaviors include disordered eating. In this project, we sought to better understand individual and social risk factors for developing disordered eating behaviors. We measured a cognitive process that can occur within the self (rumination) or between the self and others (co-rumination), two concepts previously linked to other internalizing disorders, including …
