Continuity Of Care In The Post-Partum Period, Ashley Quezada

MSN Capstone Projects

Maternal mortality rates in the United States have been a growing concern over the past decade, with rates continuing to climb as recent studies have been published. The total maternal mortality rate in the United States in 2018 was 17.4 and has increased to 32.9 as of 2021, while other developed countries continue to decline (Hoyert, 2023). The maternal mortality rate is the number of deaths per 100,000 live births. More than 50% of pregnancy-related deaths in the United States occur after delivery, in the post-partum period (Melillo, 2020). The purpose of this report is to not only bring light …

Biophysical Factors Affecting Habitat Suitability For Crassostrea Virginica, Jason D. Tilley

Dissertations

Oyster reefs provide a variety of important ecosystem services. However, the mortality rate of eastern oyster, Crassostrea virginica, the dominant species that produces oyster reefs in the northern Gulf of Mexico, is increasing at an alarming rate due to a variety of abiotic and biological factors. I examined how biophysical factors, including the less-studied fatty acid profiles of the suspended particulate matter on which oysters feed, influenced morphometric condition of C. virginica.

I sampled suspended particulate matter (SPM) and oysters in-situ in the western Mississippi Sound, which historically supported the majority of oyster production in Mississippi waters. Sampling …

Characterizing Stress Granule Regulation By Pas Kinase, Ataxin-2 And Ptc6 And Investigating The Lifespan Of Covid-19 Virus On Currency, Colleen R. Newey

Theses and Dissertations

The protein Ataxin-2 is a known positive regulator of stress granules in humans, mice and yeast (known as yeast PBP1). Due to the role that stress granules play in diseases including Amyotrophic Lateral Sclerosis (ALS) and cancer, this thesis investigates the role of Ataxin-2 and its protein binding partners in stress granule development and its effects on various metabolic phenotypes of the cell. PAS kinase is a sensory protein kinase, conserved from yeast to man, which regulates respiration and lipid biosynthesis. Our lab discovered that PAS kinase phosphorylates and activates Ataxin-2 in yeast, and that PAS kinase overexpression enhances localization …

Soil Health In American Sports Fields, Miria C. Barnes

Theses and Dissertations

Healthy soils are essential for sustaining the world's ecosystems and maintaining human lifestyles. The adoption of biological, chemical, and physical analyses to assess soil health is a relatively new concept with a paucity of scientific work assessing how these metrics are affected by field management in urban systems Soil samples (n = 110) were collected from a diverse range of sports fields and, for comparative purposes, golf courses, farm fields, non-sport urban, undisturbed forest, and non-vegetated sandy soils. The samples were then analyzed using biological, chemical, and physical metrics to determine if there were significant differences between sport/golf venues and …

Interfacial Properties Of Hybrid Lipid-Polymer Bilayers: Applications In Drug Delivery And Biosensors, Keith L. Willes

Theses and Dissertations

Amphiphilic block copolymers are unique macro-molecules capable of self-assembling into bilayers analogous to naturally occurring lipid membranes. When combined with lipids, these copolymers form hybrid membranes with unique and sometimes unpredictable properties, including increased chemical and mechanical stability. These synthetically enhanced biological structures represent a versatile platform suitable for a wide range of applications, from advanced biosensing devices to drug delivery systems. The realization of these advancements necessitates a deep understanding of material properties, including the ability to predict and control interfacial behaviors. It has been shown that in the case of pure lipid membranes, interfacial behaviors are dominated by …

Advancements In Levitated Optomechanics: Exploring Plasmon-Enhanced Light-Matter Interactions In Optical Trapping, Siavash Mirzaei Ghormish

Theses and Dissertations

Optical trapping of metallic nanoparticles investigates phenomena at the interface of plasmonics and optical micromanipulation. This thesis combines ideas from the optical properties of metals, originating in solid-state physics, with the force mechanisms resulting from optical trapping. I explore the influence of enhanced light-matter interaction due to the plasmon resonances of gold particles on their trapping properties. I present theories for trapping mechanisms of gold metallic particles and then verify these theories through experiments. Optical trapping of metallic nanoparticles is considered challenging, especially in air, as they are highly absorbing and reflecting at optical wavelengths. Yet the optical levitation of …

Mitochondrial Dna Variants At Low-Level Heteroplasmy And Decreased Copy Numbers In Chronic Kidney Disease (Ckd) Tissues With Kidney Cancer, Yuki Kanazashi, Kazuhiro Maejima, Todd A Johnson, Shota Sasagawa, Ryosuke Jikuya, Hisashi Hasumi, Naomichi Matsumoto, Shigekatsu Maekawa, Wataru Obara, Hidewaki Nakagawa

Faculty, Staff and Student Publications

The human mitochondrial genome (mtDNA) is a circular DNA molecule with a length of 16.6 kb, which contains a total of 37 genes. Somatic mtDNA mutations accumulate with age and environmental exposure, and some types of mtDNA variants may play a role in carcinogenesis. Recent studies observed mtDNA variants not only in kidney tumors but also in adjacent kidney tissues, and mtDNA dysfunction results in kidney injury, including chronic kidney disease (CKD). To investigate whether a relationship exists between heteroplasmic mtDNA variants and kidney function, we performed ultra-deep sequencing (30,000×) based on long-range PCR of DNA from 77 non-tumor kidney …

An optimized hepatocellular carcinoma (HCC)-targeted methylation next generation sequencing assay was developed to discover HCC-associated methylation markers directly from urine for HCC screening. Urine cell-free DNA (ucfDNA) isolated from a discovery cohort of 31 non-HCC and 30 HCC was used for biomarker discovery, identifying 29 genes with differentially methylated regions (DMRs). Methylation-specific qPCR (MSqPCR) assays were developed to verify the selected DMRs corresponding to 8 genes (GRASP, CCND2, HOXA9, BMP4, VIM, EMX1, SFRP1, and ECE). Using archived ucfDNA, methylation of GRASP, HOXA9, BMP4, and ECE1, were found to be significantly different (p < 0.05) between HCC and non-HCC patients. The four markers together with previously reported GSTP1 and RASSF1A markers were assessed as a 6-marker panel in an independent training cohort of 87 non-HCC and 78 HCC using logistic regression modeling. AUROC of 0.908 (95% CI, 0.8656-0.9252) was identified for the 6-marker panel with AFP, which was significantly higher than AFP-alone (AUROC 0.841 (95% CI, 0.778-0.904), p = 0.0026). Applying backward selection method, a 4-marker panel was found to exhibit similar performance to the 6-marker panel with AFP having 80% sensitivity compared to 29.5% by AFP-alone at a specificity of 85%. This study supports the potential use of methylated transrenal ucfDNA for HCC screening.

Systematic Comparison Of Nonviral Gene Delivery Strategies For Efficient Co-Expression Of Two Transgenes In Human Mesenchymal Stem Cells, Tyler Kozisek, Luke Samuelson, Andrew Hamann, Angela K. Pannier

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background Human mesenchymal stem cells (hMSCs) are being researched for cell-based therapies due to a host of unique properties, however, genetic modification of hMSCs, accomplished through nonviral gene delivery, could greatly advance their therapeutic potential. Furthermore, expression of multiple transgenes in hMSCs could greatly advance their clinical significance for treatment of multifaceted diseases, as individual transgenes could be expressed that target separate pathogenic drivers of complex diseases. Expressing multiple transgenes can be accomplished by delivering multiple DNA vectors encoding for each transgene, or by delivering a single poly-cistronic vector that encodes for each transgene and accomplishes expression through either use …

Exploring Regular And Turbulent Flow States In Active Nematic Channel Flow Via Exact Coherent Structures And Their Invariant Manifolds, Caleb G. Wagner, Rumayel H. Pallock, Jae Sung Park, Michael M. Norton, Piyush Grover

Department of Mechanical and Materials Engineering: Faculty Publications

This work is a unified study of stable and unstable steady states of 2D active nematic channel flow using the framework of Exact Coherent Structures (ECSs). ECSs are stationary, periodic, quasiperiodic, or traveling wave solutions of the governing equations that, together with their invariant manifolds, organize the dynamics of nonlinear continuum systems. We extend our earlier work on ECSs in the preturbulent regime by performing a comprehensive study of stable and unstable ECSs for a wide range of activity values spanning the preturbulent and turbulent regimes. In the weakly turbulent regime, we compute more than 200 unstable ECSs that coexist …

An Examination Of The African American Male Perception Of Church Attendance, Edward D. Gaston Jr.

Doctoral Dissertations and Projects

The variances among religious groups in the U.S. have been presumed to have weakened, yet class and ethnic variances have been largely overlooked by sociology (Wilde et. al., 2018, as cited in Pyle & Davidson, 2014). Though some research focuses explicitly on African American (AA) men, (Fitzgerald, 2010; Davis, 2020; Truss, 2018) the researcher discovered little evidence emphasizing AA men who are de-churched (Trends in the black church: More faithful, but not immune to decline, 2021; Dechurched: Witness & Outreach, 2021, para 1). The purpose of this qualitative, phenomenological study is to understand why AA males are increasingly becoming religiously …

Thomas Jefferson: Slavery, Education, And The Public Mind, Brendan Lenahan

Doctoral Dissertations and Projects

Thomas Jefferson’s autobiography reveals his continual struggle against slavery and his frustration at the resistance of the “public mind” in Virginia, predominantly composed of slave-owning aristocrats. Despite vocal condemnations of slavery, attempts to translate his anti-slavery stance into formal documents faced significant resistance from the society he aimed to change. Even within the House of Burgess, Jefferson's support for a bill allowing individual slave owners to free their slaves was met with contempt. His draft of the Declaration of Independence, condemning the King for slavery, was revised by delegates, impeded by both northern financiers of the slave trade and southern …
