Analyzing The Impact Of Sunscreen Pollutants On The Development Of Lytechinus Variegatus, Christina M. Lillenas, Chesney J. Anderson, Ann M. Buchmann

Nebraska Academy of Sciences: Programs and Proceedings

Lytechinus variegatus or the variegated sea urchin is found in shallow, tropical waters. Lytechinus variegatus can be found in sandy reef beds, and sea grass, covered in algae and debris to protect itself from the UV rays and predators. Sea urchins play a crucial role in coral reef ecosystems. Sea urchins follow an omnivore diet, feeding on algae and phytoplankton. In coral reef ecosystems, sea urchins eat unwanted algae, allowing coral reefs to continue growing and thriving. Without the presence of sea urchins in coral reef communities, algae can negatively affect the growth and success of coral reefs. Sunscreen serves …

Evaluating The Relationship Between Body Composition And Bmi In Rotc Air Force Cadets, Joseba Iparraguirre

Master of Education in Applied Human Development Graduate Projects

Body mass index (BMI) is commonly used to categorize weight status and screen for obesity-related health risk; however, BMI does not distinguish between fat mass and fat-free mass and may misclassify physically trained individuals. The purpose of this study was to evaluate the relationship between BMI and percent body fat in Reserve Officers’ Training Corps (ROTC) cadets at Bowling Green State University and to examine sex differences in BMI and adiposity. Eighteen cadets (11 males, 7 females; ages 18–23) completed anthropometric assessment for BMI calculation and body composition assessment using air displacement plethysmography (Bod Pod).

Increasing Oral-Gut Axis Health Literacy In Underserved Communities With Community-Involved, Pantry-Accessible Nutrition Education: A Conceptual Framework And Program, Audrey Kho, Yinon Gankin, Polina Pine

Chemistry: Faculty Publications and Other Works

In metropolitan U.S. areas, health inequities caused by socioeconomic disparity continue to influence oral health, nutritional status, and the risk of chronic diseases. Diets heavy in added sugars and poor in fiber and vital micronutrients are especially harmful to the oral–gut axis, which connects diet, microbial balance, inflammation, and systemic and neurological health. Due to institutional hurdles to health literacy, limited access to preventive health education, and food poverty, these eating habits are more common among low-income individuals. Only 36% of low-income parents in Chicago report being in good health, compared to 75% of parents with better incomes, underscoring the …

Inferring Genes And Biological Systems Under Selective Pressure In The Secondarily Temperate Cryonotothenioids, Esteban Cabrera

Theses, Dissertations and Culminating Projects

Notothenioid fishes represent one of the most compelling examples of adaptive radiation driven by extreme environmental change, having diversified in the chronically cold waters of the Southern Ocean. While most cryonotothenioids evolved highly specialized cold-adapted characteristics, several secondarily temperate species later re-invaded warmer environments. These lineages provide a rare opportunity to examine evolutionary reversibility and the genomic mechanisms enabling escape from extreme specialization. In this study, we investigate two secondarily temperate species, Dissostichus eleginoides and Champsocephalus esox, comparing their protein-coding orthogroups to background sets from Antarctic cryonotothenioids and basal temperate teleosts. Using phylogeny based evolutionary models (BUSTED, aBSREL, and RELAX) …

A Trajectory Of Zostera Marina (Eelgrass) Ecosystem Recovery: Pre- And Post-Hurricane Sandy Degradation In Barnegat Bay, New Jersey, Edgar A. Medina

Theses, Dissertations and Culminating Projects

Hurricane Sandy struck Barnegat Bay, New Jersey in 2012 and obliterated the benthic marine ecosystem with extensive damage to Zostera marina meadows. Previous genetic assessments of Barnegat Bay Z. marina in 2008 revealed low heterozygosity and low connectivity between populations. The great disruption caused by Hurricane Sandy motivated us to investigate the long-term effects of the storm on the genetic condition of the eelgrass populations in the year 2021. The investigation revealed improvements in heterozygosity, inbreeding, and connectivity. These findings drove us to investigate the genetics of Barnegat Bay eelgrass populations in the intervening years of 2013 and 2017 with …

Risk Of Gestational Diabetes By Aerobic And Resistance Exercise During The First And Second Trimesters, Takaki Tanamoto, George Saade, Leryn J. Reynolds, Tetsuya Kawakita

Department of Obstetrics & Gynecology Faculty Publications

Objective

While some studies have shown that exercise reduces the incidence of gestational diabetes mellitus (GDM), there is limited evidence on whether aerobic or resistance exercise is more beneficial. This study aimed to examine the rate of GDM according to the type of exercise during early pregnancy.

Study design

We analyzed data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b), a prospective cohort of individuals enrolled during the first and second trimesters. We excluded participants with pregestational diabetes or delivery < 20 weeks. The primary exposure was either aerobic or resistance exercises in the first or second trimester. For each trimester, the metabolic equivalent of task hours per week (MET-h/week) was calculated for each exercise. Participants were grouped as follows: "Aerobic exercise" (≥7.5 MET-h/week from aerobic exercises), "Resistance exercise" (≥2 times/week from resistance exercises), "Both types of exercise" (≥7.5 MET-h/week from aerobic exercise and ≥2 times/week from resistance exercises), and "Insufficient exercise" (≤7.5 MET-h/week from aerobic exercise and ≤2 times/week from resistance exercises). Our primary outcome was GDM. Adjusted relative risks (aRRs) with 95% confidence intervals (95% CIs) were calculated using modified Poisson regression, adjusting for potential confounders.

Results

In both the first and second trimesters, analyses included 9049 individuals. In the first trimester, individuals who performed …

An Evidence-Based Approach To Standardizing Occupational Therapy Services For Functional Neurological Disorder: Protocol Development And Provider Education, Kimberly Yuen

OTD Capstones

Functional Neurological Disorder is a complex neurological condition that continues to be misinterpreted and stigmatized by healthcare practitioners. Occupational therapists play a vital role in the care team for an individual with FND, as their scope of practice helps to empower individuals with this condition to return to daily, meaningful occupations. However, there remains a lack of evidence-based protocols and resources for occupational therapists to utilize when treating functional neurological disorder (FND), resulting in minimized confidence and understanding of how to treat this population. This capstone project addressed these concerns through the creation of multiple deliverables to help improve clinician …

The Functional Significance Of Plk1 Phosphorylation Of Nrf2 In Prostate Cancer Progression, Maria Nur

Theses and Dissertations--Toxicology and Cancer Biology

Prostate cancer progression and therapeutic resistance are closely linked to alterations in redox homeostasis and cell cycle regulation. Nuclear factor erythroid 2–related factor 2 (NRF2) is a master regulator of antioxidant responses, yet the mechanisms integrating cell cycle signaling with NRF2 activity in prostate cancer remain poorly defined. In this study, we identify polo‑like kinase 1 (PLK1) as a novel regulator of NRF2 through direct phosphorylation at serine 253 (S253). Using bioinformatic prediction, mass spectrometry, in vitro kinase assays, and cell‑based analyses, we demonstrate that PLK1 phosphorylates NRF2 at S253 in a cell cycle–dependent manner, with maximal phosphorylation during mitosis. …

Limitations Of Reproductive Manipulation By Bacterial Endosymbionts In A Spider Host, Jordyn D. Proctor

Theses and Dissertations--Entomology

Maternally inherited bacterial endosymbionts are common in arthropods. Many of these bacteria manipulate host reproduction to favor the production of infected females, thereby increasing bacterial prevalence in the host population, even if cost is incurred to the host. However, there are also many factors that may inhibit symbionts’ ability to spread in host populations, including environmental constraints, symbiont-imposed costs on the host, interactions with co-infecting bacteria, or host biology. I explored two aspects of symbiont biology within a spider host, Mermessus fradeorum (Linyphiidae), which has varying combinations of up to five different bacterial endosymbionts in local populations: Rickettsiella, Tisiphia …

Impacts Of Livestock Dewormers On Dung Beetle Foraging Choices Across Spatial Scales, Madison L. Kluge

Theses and Dissertations--Entomology

Dung beetles provide ecosystem services in pasture systems but are vulnerable to chemical residues in livestock dung. Parasiticides containing macrocyclic lactones (MLs) are used to control parasites in livestock and are excreted unmetabolized in dung, exposing non-target organisms to these compounds. We used a multi-scale approach to examine whether ML residues alter dung beetle foraging ecology. At the field scale, we assessed dung beetle abundance and community composition using traps baited with dung from untreated cattle and cattle treated with ivermectin, moxidectin, or eprinomectin across eight farms and natural areas. At a smaller scale, we conducted behavioral assays to quantify …

Flow Injection Determination Of Fluoride For Total Organic Fluorine Analysis, Memona Zulafiqar

Chemistry & Biochemistry Theses

Poly- and perfluoroalkyl substances (PFAS) are anthropogenic chemicals that have gained increasing attention due to their association with a wide range of adverse health effects. These compounds are highly diverse, with approximately 15,000 PFAS reported. Their exceptional environmental stability and strong tendency to bioaccumulate result in environmentally relevant concentrations that typically occur at very low levels, often in the ng L⁻¹ range. This chemical diversity presents a major analytical challenge, as reference standards are available for only a limited number of PFAS. Consequently, conventional targeted analytical methods frequently quantify less than 1% of the total PFAS present, leading to a …

Human Milk Feeding And Its Impact On The Incidence Of Necrotizing Enterocolitis, Maya C. Kern

Nursing | Senior Theses

One of the leading causes of morbidity and death for preterm and very low birth weight (VLBW) newborns is still necrotizing enterocolitis (NEC). Existing literature consistently shows that the bioactive, anti-inflammatory, and microbiome-supporting components of human breast milk, including donor human milk, significantly lower the incidence of NEC. However, a lot of infants are forced to rely on formula and nutrient fortifiers because they cannot obtain maternal or donor milk. A critical gap persists regarding whether human milk derived fortifiers offer greater NEC protection than bovine derived fortifiers in infants who must receive formula. This thesis examines three interconnected themes; …

Black Americans' Interactions With Law Enforcement: The Black Church's Response, Shalanda Ehiozee

Doctor of Ministry

This research interrogates the disproportionate frequency of lethal law enforcement encounters involving Black Americans, contextualizing these fatalities within the systemic racial hierarchies foundational to the United States. By tracing the historical evolution of policing from antebellum slave patrols to contemporary practice, this study contends that modern law enforcement serves as a sophisticated mechanism of racial and social control.

To examine this phenomenon, the research employs a qualitative, multidimensional methodology that synthesizes Comparative Caste Analysis, case study examination, and a Christological framework. This inquiry is further bolstered by a longitudinal analysis of African American ecclesiological activism, culminating in a theological reflection …
