Global Trends In Dietary Exposure To Polychlorinated Naphthalenes (Pcns): A Review Of Contamination Levels And Health Implications, Vhodaho Nevondo, Okechukwu Jonathan Okonkwo

Engineering and Technology Journal

Polychlorinated naphthalenes (PCNs) belong to a class of persistent organic pollutants that are structurally related to chlorinated dibenzo-p-dioxins, dibenzofurans, and other chlorinated biphenyls as a result of the presence of benzene rings in their respective structures. Additionally, they display high levels of persistence in the environment, bioaccumulative, and dioxin-like toxicities characteristics. Although the production and use of PCNs is either banned or greatly regulated in several countries around the globe, unintentional production in industrial thermal processes and legacy usage have resulted in the ubiquity of these compounds in the environment and the food chain. Several studies have shown various exposure …

Mechanistic Insights Of Enterolactone Within 3t3-L1 Adipocyte Cells, Merritt Smith

Liberty University Research Week

Type 2 diabetes mellitus (T2D) is one of the leading causes of morbidity and mortality in the United States, with approximately 25% of healthcare expenditures directed toward its management and associated metabolic complications. In response to the urgent need for novel therapeutic strategies, recent research has focused on bioactive compounds derived from dietary sources. In light of that, we identified the plant lignan matairesinol (MA) and its gut-derived metabolite, enterolactone (ENL), as agents capable of enhancing glucose uptake in 3T3-L1 differentiated adipocytes. These results suggest that enterolactone may represent a promising dietary supplement for improving glycemic control in patients with …

“Slaves To Sin:” Harnessing Neuroplasticity To Defeat Habitual Behaviors, Charity Parrott

Liberty University Research Week

How does neuroplasticity affect the life of a Christian? This thesis will seek to address the concepts of habit formation, neuroplasticity, and top-down control through a neurobiological perspective, and how they relate to the Biblical concept of habitual sin. Discoveries in neuroplasticity have revealed the brain to be a malleable organ, capable of rewiring neural connections and, in the hippocampus region, neurogenesis, or the creation of new neurons (Fuchs & Flügge, 2014). This thesis will compile research in neuroplasticity, explore the biological reasons behind the difficulty in escaping patterns of sin, and connect Biblical-based strategies for sin prevention with neurobiology. …

The Impact Of Maternal Western-Style Diet On Ovarian Anti-Müllerian Hormone Expression And Localization In Mouse Offspring, Kati Platt, Chase Shinabery, Jackson Mellish, Madison Howard, Soriya Scott

Liberty University Research Week

The Western diet, characterized by high saturated fat and sucrose intake, has become increasingly prevalent in the United States and globally, yet its effects on female reproductive health across life stages remain insufficiently understood. In adult human females, consumption of a Western-style diet has been linked to an increase in premenstrual symptoms, higher rates of depression, and elevated free estradiol levels, contributing to an increased risk of breast cancer, particularly in postmenopausal women. In human female children, Western diet consumption has been linked to an early onset of secondary sexual characteristics and premature menarche. Maternal consumption of this diet during …

Regulation Of Glut5 Expression And Fructose Uptake By Heat Stress And Pro-Inflammatory Cytokines In Enterocytes, Landri Shope, Gretchka Mair

Liberty University Research Week

Diabetes is an escalating global health concern, affecting 11.1% of the adult population worldwide, with over 90% of cases classified as type 2 diabetes mellitus (T2DM) (Facts & Figures., n.d.). T2DM is characterized by chronic fasting hyperglycemia and is increasingly associated with alterations in the gut microbiome. This study tests the hypothesis that heat stress, a gut dysbiosis-associated stressor, will upregulate the fructose transporter GLUT5 in enterocytes. Increased GLUT5 expression may enhance intestinal fructose uptake, thereby contributing to worsened glycemic control in T2DM. While the mechanism linking inflammation and impaired glucose homeostasis remains elusive, emerging evidence supports strong associations among …

Investigating Nutritionally Derived Treatments For Metabolic Disease: Enterolactone And Its Effect On Glp-1 And Pyy Secretion, Aidan Clancy

Liberty University Research Week

Gut-derived hormones such as glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) play essential roles in maintaining glucose homeostasis and appetite regulation. These hormones are primarily secreted by enteroendocrine L cells in response to nutrient signaling in the gut. Emerging evidence suggests that polyphenolic compounds and their metabolites may influence gut hormone secretion. Enterolactone (ENL), a microbial metabolite of the dietary lignan, matairesinol, is of particular interest due to its reported anti-diabetic properties. In this study, we propose to test whether ENL can modulate the secretion of GLP-1 and PYY in L cells in vitro, thereby identifying a potential mechanism by …

Real World Fertility: From Participatory Research To Clinical Trial, Belinda Tan, Azure Grant, Ayla Barmmer

Oxford ICSB

Nutritional supplements are widely popular for female reproductive health, but their ingredients are typically studied in isolation in the laboratory. Finished products make claims based on these isolated studies, creating a gap in which impact of multi-nutrient formulas in the real world are not investigated, largely due to high research costs. Decentralized clinical research methods are modernizing clinical trials, leading to affordable, efficient evidence generation in large representative populations. Utilizing a decentralized research platform, we tested the hypothesis that specific supplement protocols would be associated with improved female health and fertility in a real world cohort. We present a novel …

Health Sciences Student Scholarship

More female athletes are participating in sports today than ever before, yet they remain underrepresented in sport and exercise science (SES) research. According to a 2021 review, 34% of SES research participants are females and just 6% of studies used female-only designs. Female athletes are also at an increased risk for low energy availability (LEA), or a mismatch between energy intake and exercise energy expenditure. However, the representation of women in research related to LEA remains unclear. PURPOSE: This study aimed to (a) evaluate the representation of girls, women, and female athletes in LEA research, and (b) explore methodological characteristics …

Using Lean Body Mass To Calculate Resting Metabolic Rate Across Gender Identities, Kara Dixon, Liza Goetcheus, Brett R. Ely

Health Sciences Student Scholarship

Accurate estimate of resting metabolic rate (RMR) is important for tailoring nutrition support in clinical settings. Metabolic rate is often calculated using the Harris-Benedict equations, which estimate metabolic rate using separate equations for men and women. PURPOSE: This study aims to develop a more inclusive, single predictive equation based on lean body mass instead of gender. METHODS: Six healthy individuals (Age: 22±5; BMI: 22.3±0.7) underwent assessment of resting metabolic rate (RMR) using indirect calorimetry, and full-body dual energy x-ray absorptiometry to measure lean body mass.

Department of Nutrition Student Projects

The prevalence of Autism spectrum disorder (ASD) has risen significantly over the past five decades, now affecting approximately 1 in 31 children. This literature review examined whether folinic acid, compared with other forms of vitamin B9 (synthetic folic acid, dietary folate, and 5-methyltetrahydrofolate), modulates ASD symptoms including verbal communication, motor skills and social interaction, particularly in children positive for folate receptor alpha autoantibodies (FRAAs). A thorough search of PubMed, Google Scholar, Nature, and ScienceDirect, primarily from 2015–2026, identified five randomized controlled trials (RCTs) and one meta-analysis evaluating folinic acid at standardized doses of 2 mg/kg/day with a maximum dose of …

Implementing A Nutrition Screening, Education, And Risk Reduction Framework In Optometric Care To Prevent Diabetic Retinopathy In Adults With T2dm, Juliana M. Varanelli

Department of Nutrition Student Projects

Diabetic retinopathy (DR) is a leading cause of preventable vision loss among adults with Type 2 diabetes mellitus (T2DM), driven largely by chronic hyperglycemia, oxidative stress, and inflammation. Despite strong evidence supporting the role of nutrition in modifying these risk factors, nutrition screening and counseling are not routinely integrated into optometric care. This project aimed to develop a practical, evidence-based framework to incorporate nutrition screening, patient education, and referral pathways into comprehensive optometric practice to support prevention and reduce the onset and progression of diabetic retinopathy.

This project involved a literature review of peer-reviewed research and clinical guidelines related to …

The Price Of Democracy: How Federal Tax Receipts Can Enhance Public Awareness, Transparency, And Civic Discourse, Hannah Bordeau

Honors Theses

Each year, the IRS collects roughly $2.18 trillion in income taxes alone, accounting for approximately 48% of the government's total revenue. However, the IRS does not audit individual tax receipts for citizens, preventing them from seeing a visual breakdown of where their money is allocated. To better understand how citizens feel about governmental spending, this project will utilize a mixed-methods approach, incorporating a qualitative case study to explore the developments (or lack thereof) regarding a “tax receipt” and conducting interviews to gain insights into public perception of a tax receipt program. In addition to the interviews, this project will explore …

Ai-Driven Computer Vision For Automated Ripeness Detection In Tomato Plants, Austin Ebbing

Honors Theses

This work presents a computer vision-based approach for automated ripeness detection in tomato plants. The system leverages a YOLOv8 segmentation model trained on a publicly available dataset to detect and isolate individual tomatoes within complex visual environments. While segmentation provides an initial estimate of tomato regions, additional processing is required to remove non-fruit artifacts such as stems and leaves that may interfere with analysis. To address this, an edge-constrained region growing method is used to tighten segmentation masks by removing unwanted structures such as stems and leaves while preserving the underlying fruit. Ripeness is then estimated using a color-based analysis …

Exercise As A Non-Pharmacological Intervention For The Prevention And Delay Of Alzheimer’S Disease And Dementia, Eden Culver

Honors Theses

Alzheimer’s disease (AD) and related dementias are rapidly increasing public health concerns due to aging populations and rising life expectancy. Alzheimer’s disease is characterized by progressive neurodegeneration associated with amyloid-β plaques, tau neurofibrillary tangles, neuroinflammation, oxidative stress, and neuronal loss, leading to impairments in memory, cognition, and daily functioning. Because there is currently no cure for Alzheimer’s disease, identifying effective non-pharmacological prevention strategies is essential. This paper examines the role of physical exercise as a preventive and protective intervention for delaying the onset and progression of Alzheimer’s disease and dementia. Current research demonstrates that exercise supports brain health through several …

Wherefore The Magic? The Evolutionary Role Of Psilocybin In Nature, K. J. Matthews Nicholass, I. Flis, M. E. Hanley, M. E. Knight, S. M. Lane, G. Littlejohn, M. D.F. Thom, R. A. Billington, R. Boden, R. Cummins, B. J. Green, C. Griffin, S. Jones, D. Salmon, I. Sleep, N. Smirnoff, J. S. Ellis

School of Biological and Marine Sciences

Research into psychedelic compounds is in resurgence because of the exciting potential for their use in the treatment of psychiatric and mental health disorders. Despite this revival, remarkably little is known about their evolution. One of the most intriguing psychedelic compounds is psilocybin, the compound found in ‘magic’ mushrooms and used in ritual ceremonies in North America for generations. Associated with agaricomycete fungi across eight distantly related genera, psilocybin acts in a similar way to the neurotransmitter serotonin, yet how and why natural selection favoured its biosynthesis remains unclear. Given the resemblance to serotonin, a highly conserved neurotransmitter across invertebrates …

Development Of A Survey For Assessing Women’S Perceptions Of Weight-Related Side Effects Of Hormonal Contraceptives, Ayla Mae Laro

Theses

Background —Hormonal contraceptives (HCs) are widely used among reproductive-age women, yet concerns about weight gain remain common and are frequently cited as a reason for dissatisfaction or discontinuation. Dissatisfaction and discontinuation of HCs can lead to unintended pregnancy—a serious health concern in the United States. Existing research has largely focused on objectively measured weight change as a secondary outcome rather than on perceptions of weight-related side effects, and no validated tool currently assesses these perceptions. Additionally, studies have historically failed to include women with overweight and obesity. This cross-sectional mixed-methods study developed and face-validated an online survey measuring reproductive-age women’s …
