Developing A Tool To Measure Resistance To Sustainable Food Choices: A Pilot Study In Ireland And The Netherlands, Kate Flanagan, Bart Sinteur, Patricia J. Bulsing, John M. Kearney

SURE Journal: Science Undergraduate Research Experience Journal

Consumer uptake of a sustainable diet is critical for addressing environmental challenges and promoting public health. Understanding why consumers resist adopting sustainable eating habits can inform targeted interventions and policies. This pilot study examines whether a newly developed scale can effectively detect consumer resistance to a sustainable diet. Currently, there is a lack of research on a tool to measure consumer resistance to a sustainable diet, highlighting the need for a reliable instrument.

The aim of this study is to develop a scale, based on existing literature, to measure consumer resistance to a sustainable diet. Additionally, the study aims to …

Investigating The Role And Mechanism Of Faecalibacterium Prausnitzii In Fatty Acid Metabolism And Obesity Using The Drosophila Melanogaster Model, Jackson Head, Whitley Whitehead

Student Scholar Symposium

The obesity epidemic has increased to enormous numbers with 890 million adults being classified as obese (BMI≥30). Obesity is of extreme concern as it is a comorbidity to coronary heart disease, type-2 diabetes, and cancer. Although obesity has classically been attributed to genetics and lifestyle, there is a growing interest in other factors, including the gut microbiome. Germ-free mice are resistant to weight gain even when placed on a high-calorie diet, establishing that metabolites produced by gut microbiota can dramatically inhibit metabolism. Here, we use Faecalibacterium prausnitzii, which has been previously shown to be reduced in obese individuals; however, …

Indole Improves Outcomes Of Cronobacter Sakazakii Infection In C. Elegans Through Ahr-1, Cayden Durrough

Student Scholar Symposium

Necrotizing enterocolitis (NEC) is a severe gastrointestinal disease primarily affecting premature infants. Toll-like receptor 4 (TLR4)-mediated epithelial damage allows microbial translocation, triggering inflammation that can lead to sepsis and death. The aryl hydrocarbon receptor (AhR) is a ligand-dependent transcription factor, and AhR ligands have been shown to prevent NEC in a mouse model. Indole, an AhR ligand, has been reported to extend the healthspan of C. elegans, and we have shown previously it mitigates poor outcomes in wild-type worms infected with Cronobacter sakazakii (Cs), a bacterial pathogen linked to NEC. We hypothesized that C. elegans must express ahr-1, the ortholog …

Understanding The Role Of Hd5 In Colonic Epithelial Cell Death, Maryam M. Gerges, Amanda D. Williams

Student Scholar Symposium

Inflammatory bowel disease (IBD) is an autoimmune disorder where the immune system attacks healthy tissue. IBD can occur in both adults and children, describing Ulcerative Colitis (UC) and Crohn’s Colitis (CC). Our lab studies human alpha defensin 5 (HD5), an antimicrobial peptide that normally maintains small intestinal sterility. However, in CC patients, HD5 is overexpressed in the colon. Preliminary data suggests that HD5 increases colonic cell death. This project aims to determine if HD5 induces apoptosis and its mechanisms. To this end, we will test if the suppression of caspase enzymes with a pan-caspase inhibitor reduces cell death triggered by …

Functionality Of The Ryanodine Receptor Type 1 (Ryr1) In The Development Of Malignant Hyperthermia (Mh), Cesar Medina, Joshua Owens

Student Scholar Symposium

Malignant Hyperthermia (MH) is a rare but potentially lethal pharmacogenetic disorder, affecting roughly 1 in 30,000 children and 1 in 100,000 adults undergoing surgery. MH can be triggered by agents used for general anesthesia. These may include volatile anesthetics such as sevoflurane, isoflurane, desflurane, halothane or depolarizing neuromuscular blockers such as succinylcholine. Upon administration of a trigger, an MH susceptible (MHS) patient can develop a hypermetabolic state during the intraoperative or postoperative periods. If not treated quickly, an MH episode could result in organ dysfunction or death. The primary mechanisms involved in the development of an MH crisis include the …

Buffer Vs. Swabs: Efficacy Of Carrier Nucleic Acids In Robotic Extractions, Shawn Cecil

Honors Projects

This study compared the efficiency of two carrier nucleic acid methods, specifically using salmon sperm DNA (spDNA), in robotic solid-phase extractions of cotton swab samples. Robotic extractions reduce processing time and workload but result in substantially lower DNA recovery than manual organic extraction. This research tested 10 µg of spDNA being added to the lysis buffer or pre-treating the swabs with it before DNA was added. Both methods showed a significant increase in recovery compared to extractions with no carrier. In the buffer extractions, recovery ranged from 69.4% to 117.5% and the swabs being pre-treated ranged from 84.2% to 125.8% …

Investigating Factors That Affect Total Ige Antibody Levels Of A Canine Population In Louisville, Ky, Iris N. Gillespie

Undergraduate Theses

Canine atopic dermatitis (CAD) is a genetically predisposed condition that causes inflammatory and pruritic (itchy) skin reactions in response to environmental and food allergens. The main purpose of this study is to determine if there is a correlation between pollen counts and total canine IgE antibody levels of dogs living in Louisville, KY. Additionally, data is analyzed to look for trends documented in previous studies related to the impacts of sex, age, and allergic symptoms on total IgE count. In collaboration with the Downtown Animal Hospital, blood samples were drawn from 16 dogs at one point in February (when pollen …

Dendrimer Gel Nanoparticles With Dual-Targeting Of Upar And Ribonucleotide Reductase R2 Influence Necrosis, Apoptosis, And Cell Cycle Arrest In Triple-Negative Breast Cancer, Hsin Yin Chuang, Yue-Wern Huang, Hu Yang

Biological Sciences Faculty Research & Creative Works

Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype with limited treatment options due to the absence of estrogen (ER), progesterone (PR), and human epidermal growth factor receptor 2 (HER2) receptors. We previously developed highly adaptable polyamidoamine (PAMAM) dendrimer-based gel nanoparticles (GDP-uPA/GTI) with dual-targeting capabilities against urokinase-type plasminogen activator receptor (uPAR) and ribonucleotide reductase R2 (R2) to achieve selective antitumor effects. In this study, we investigated the underlying mechanisms of GDP-uPA/GTI-induced tumor inhibition. In vivo, GDP-uPA/GTI significantly downregulated R2 expression and activated caspase 8 and caspase 3, indicating caspase-dependent apoptosis. Histological evaluation of major organs revealed no observable toxicity. …

A Molecular Mechanism Of Epithelial To Mesenchymal Transition (Emt): An Evidence Based Lesson Applying Molecular Biology Through The Lens Of Cancer, Sophie Hasson, Melissa Rowland-Goldsmith

Open Educational Resources

This lesson aims to strengthen students’ critical thinking and molecular biology data analysis skills as well as their understanding of concepts related to the hallmark of cancer: tissue invasion and metastasis. Students begin by learning about the invasion of cancer cells, Epithelial-Mesenchymal Transition (EMT), and an important protein involved in EMT: E-cadherin. They then apply molecular biology knowledge to analyze data from multiple papers to infer the relationship between Snail and E-cadherin in different types of cancers. Next, they continue to interpret data from many papers to determine that a repressor transcription factor is present during EMT in cancer cells …

Improving Coral Restoration Outcomes Through Novel Molecular Applications, Matthew H. Gamache

USF Tampa Graduate Theses and Dissertations

Coral reef ecosystems are declining globally from numerous stressors, including localized pollution, disease, and marine heatwaves induced by climate change. To preserve these ecosystems, it is critical to identify corals that can withstand stressors—primarily future marine heatwaves—and prioritize them for coral restoration efforts until these stressors are mitigated. Coral responses to thermal stress can be influenced by several partners, including mutualistic microalgae and a vast prokaryotic community. Here, I use advanced molecular techniques to examine which partners (coral host, algal symbiont, and microbial communities) are associated with coral health, how they contribute to holobiont physiology, and their potential to increase …
