Circadian Influences On Glycemic Control In 24-Hr Fasts Initiated At Different Mealtimes, Elizabeth Z. Gipson

Theses and Dissertations

This study investigated whether the timing of a 24-hour fast influences indicators of glycemic control throughout the duration of the fast or upon refeeding. Twenty-four adults who have overweight or obesity (13 female, 11 male) completed this randomized crossover study involving three 24-hour fasts initiated at either 8:00 am, 1:00 pm, or 6:00 pm followed by a 75 g oral glucose tolerance test (OGTT) which lasted 2 hours. Continuous glucose monitors (CGMs) were employed to track interstitial glucose throughout each fast and OGTT. Plasma samples for insulin, glucagon, glucagon-like peptide-1 (GLP-1), and glucose-dependent insulinotropic polypeptide (GIP) were collected at the …

Bank Stocks And Roosevelt’S Bank Holiday, Marc Weidenmier, Angela Vossmeyer, Nathan Stella, Oncel Aldanmaz

Business Faculty Articles and Research

Roosevelt’s Bank Holiday in March 1933 aimed to halt bank runs and implement licensing for banks. Using a new hand-collected daily database, we examine how bank stocks and bond markets responded to this sweeping regulation. We find that New York City banks saw significant negative abnormal returns, while Chicago banks experienced positive returns, highlighting regional differences in perceptions of the policy. Corporate bond yields fell by 1.4 percentage points, lowering interest rates. Our findings show how markets reacted differently across regions and asset classes to this critical intervention.

Chemically Mediated Communication In Mound-Building Termites, Sree Subha Ramaswamy

Theses and Dissertations

Nest-building in social insects requires layered communication to coordinate complex, functional structures for housing, protection, storage, and homeostasis. This is especially striking in mound-building termites, which construct and repair large mounds collectively despite lacking image-forming eyes. This thesis investigates how Odontotermes obesus achieves such coordination through chemical communication embedded in soil.

Using controlled two-choice assays with manipulated soils, I separated airborne volatile signals from contact non-volatile signals by baking to remove volatiles, a mesh assay that presented volatile cues without contact, and solvent extraction with reapplication of contact cues. I quantified responses in major-only, minor-only, and mixed groups at two …

The Interplay Of Oxidative Stress, Mitochondrial Dysfunction, And Neuroinflammation In Autism Spectrum Disorder: Behavioral Implications And Therapeutic Strategies, Ansab Akhtar, S K. Rahaman

School of Medicine Faculty Publications

Autism spectrum disorder (ASD) deals with several symptoms, including language and speech impairment and developmental delays. The main brain regions affected could be the prefrontal cortex (PFC) or the temporal lobe. The detrimental features could include oxidative stress, mitochondrial dysfunction, and neuroinflammation. Most often, these phenomena are interrelated and can lead to one another, creating a vicious cycle. They also influence the regulation of certain genes involved in the pathogenesis of ASD or related behavior. In the brain regions prone to these detrimental features, a cascade of free radicals, inflammatory cytokines, and mitochondrial energy disruptions is initiated. These actions during …

The Impact Of Early Life Experiences On Math Confidence, Nhu X. Hin

Master's Theses

Students form beliefs about their academic abilities through a combination of emotional experiences and early learning environments. While prior research has documented how math anxiety can undermine performance and how early experiences with math-typed activities can foster positive attitudes, less is known about how these factors collectively influence students’ math confidence. The present study investigates how math anxiety, engagement in childhood math-typed activities, and perceived support for math-related learning contribute to college students’ confidence in their math abilities. Participants (N = 102) completed self-report measures assessing each of these constructs. A multiple regression analysis revealed that the three predictors collectively …

Impact Of Urban Fine Particulate Matter Exposure On Cardiovascular Health, Shelby P. Briggs

Honors Theses

Air pollution, particularly exposure to fine particulate matter (PM2.5), poses a growing threat to cardiopulmonary health. PM2.5 consists of microscopic particles smaller than 2.5 microns in diameter and originates from industrial combustion, transportation, and urban dust. These particles are classified as xenobiotics and are capable of bypassing respiratory defenses to enter systemic circulation, where they cause oxidative stress, inflammation, and cardiovascular dysfunction. This study examines the effects of PM2.5 on cardiovascular function using a murine model. Male C57BL/6 mice were divided into control (saline), subchronic (10 µg), and chronic (100 µg) groups and were exposed weekly for 11 weeks via …

Is Social Media Use A Reason For Socially Withdrawn Individuals' Mental Health Difficulties?, Angela Grundvig

Theses and Dissertations

Studies have found a link between subtypes of social withdrawal and internalizing problems throughout most of the lifespan. However, the work conducted in adolescence is much more limited including a lack of work examining factors that might mediate the association between forms of social withdrawal and internalizing problems. Social comparison may be one way in which social withdrawal predicts internalizing problems. There has been research showing that social media usage is associated with internalizing problems. The purpose of this study was to assess (a) the associations between three subtypes of social withdrawal (shyness, avoidance, and unsociability), respectively, and indices of …

Differential Mirna Expressions Linking Environmental Risk Factors To Triple-Negative Breast Cancer Stages At Diagnosis, Amjila Bam, Yawen Hu, Xiaocheng Wu, Meng Luo, Nubaira Rizvi, Luis Del Valle, Arnold H. Zea, Fokhrul Hossain, Denise Moore Danos, Jovanny Zabaleta, Augusto Ochoa, Lucio Miele, Edward Trapido, Qingzhao Yu

School of Public Health Faculty Publications

Background/Objectives: Triple negative breast cancer (TNBC) is an aggressive, molecularly heterogeneous subtype of breast cancer, accounting for approximately 10–15% of all cases. While reproductive and metabolic factors contribute to breast cancer development, growing concerns about environmental exposures, alongside biological and socio-cultural influences, underscore the need for targeted prevention strategies across diverse populations. Despite increasing evidence linking biological, socioeconomic, and environmental factors to TNBC outcomes, the molecular mechanisms underlying these relationships remain poorly understood. Micro-RNAs (miRNAs), which regulate gene expression and play critical roles in cancer development, have emerged as potential mediators between environmental exposures and TNBC progression. The goal of …

Mental Health Disparities In Hospital Admissions For Youth With And Without Autism, Ben Pfingston, Lindsey Sneed

Journal of Social, Behavioral, and Health Sciences

The purpose of this study was to compare mental health diagnoses in a sample of youth with autism spectrum disorder (ASD) and youth without ASD (non-ASD) admitted to inpatient hospitals across the United States. We hypothesized that autistic youth would have a greater proportion of co-occurring psychiatric diagnoses compared to their typically developing peers. To do this, we conducted a cross-sectional analysis of the Healthcare Cost and Utilization Project (HCUP) 2019 Kids’ Inpatient Database (KID). We compared the proportions of co-occurring psychiatric diagnoses between autistic and typically developing youth. Compared to 21% of non-ASD admissions, 36% of the ASD admissions …

Cognitive Reserve In The Deaf/Hard Of Hearing Community: An Exploration Of Contributing Factors, Olivia B. Allaby

Theses

Cognitive reserve (CR) refers to the individual differences in how people execute tasks, allowing some to cope with cognitive challenges more effectively than others. Additionally, previous studies have established a link between age-related hearing loss and cognitive decline. However, CR and cognitive aging have not been explored extensively in those who might identify as Deaf/hard of hearing (HH). There are four features potentially unique to this community that could shape one’s CR: use of hearing technology (e.g., hearing aid), bimodal bilingualism, and social connectedness and social support. One hundred fifty-nine Deaf/hard of hearing participants completed an online survey study assessing …
