Characterization Of An Unknown Mutant C3 With A High Level Of Endogenous Replication Stress In Fission Yeast, Neha Singh Jan 2025

Characterization Of An Unknown Mutant C3 With A High Level Of Endogenous Replication Stress In Fission Yeast, Neha Singh

Browse all Theses and Dissertations

To maintain genome stability, which is essential for cell proliferation and survival, cells rely on cell cycle checkpoint pathways to deal with perturbed DNA replication or replication stress. The fission yeast Schizosaccharomyces pombe serves as a powerful model organism for studying checkpoint mechanisms because its fundamental cellular processes are highly conserved in higher eukaryotes. During a genetic screening for mutants affecting genome integrity, we identified a novel mutant called C3 that exhibits a unique phenotype. Unlike wild-type cells, where phosphorylation of the checkpoint mediator Mrc1 is typically observed only in response to exogenously induced replication stress, such as the treatment …


Induced Reduction Of N-Glycosylation Leads To Heart Failure, Anthony M. Young Jan 2025

Induced Reduction Of N-Glycosylation Leads To Heart Failure, Anthony M. Young

Browse all Theses and Dissertations

Cardiovascular disease is the leading cause of death and contributes to the increasing global prevalence of heart failure (HF). N-glycosylation is a common co-/post-translational modification where branching oligosaccharides are bound to the extracellular domain of membrane proteins. This creates a diverse range of glycan structures and requires the coordination of hundreds of regulated genes. Inherited mutations in glycan synthesis frequently present with cardiomyopathies leading to HF with reduced ejection fraction (HFrEF). Additionally, gene expression studies of HFrEF patients have shown altered expression of glycosylation-related genes, including alpha-1,3-mannosyl-glycoproten 2-beta-N acetlyglucosaminyltransferase (Mgat1). This gene encodes N-acetylglucosaminyl transferase 1 (GlcNAcT1) which is required …

Antibody production is an essential component of the immune response against pathogens. The immunoglobulin heavy chain (IgH) gene codes for the heavy chain of antibodies. The IgH constant regions Cμ, Cδ, Cγ1-4, Cα1-2, and Cε encode the five major classes of antibodies, i.e., IgM, IgD, IgG1-4, IgA1-2, and IgE, respectively. The transcription of the IgH gene and class switch from IgM to other isotypes is regulated by two 3’ IgH regulatory regions (3’IgHRRs), each of which is a cluster of three enhancer regions (hs3, hs1.2 and hs4). The genetic variations in the hs1.2 enhancer have been identified; a ~53 bp …

Characterizing The Microvesicle Particles From Keratinocytes Stimulated With Multiple Stressors, Muslima Begum

Browse all Theses and Dissertations

Many types of environmental and physical stressors act upon the skin and can initiate inflammation, systemic effects, and even damage to internal organs. Recent studies have identified that these harmful events are driven by the release of subcellular microvesicle particles (MVPs), an inflammatory process promoted by the glycerophosphocholines-derived lipid mediator, Platelet-activating Factor (PAF). These harmful effects are driven by the release of MVPs, a process promoted by the inflammatory lipid mediator, PAF. We have previously demonstrated that exposure of human HaCaT keratinocyte and mouse skin to stressors such as thermal burn injury, ultraviolet B (UVB) radiation, and topical photodynamic therapy …

Birth On Mother Earth: Mitigating The Maternal Health Crisis, Jill C. Engle Jan 2025

Birth On Mother Earth: Mitigating The Maternal Health Crisis, Jill C. Engle

Faculty Scholarship

Maternal health outcomes in the U.S. are remarkably poor, especially when compared to those in other industrialized countries. For example, our maternal death rate is more than twice that of Canada’s. Women of color in the U.S. suffer maternal morbidity and mortality at rates considerably higher than white women. Indigenous women experience the worst maternal health outcomes of all. Yet, most maternal deaths and injuries are preventable. Furthermore, rates of maternal harm, including death, are lower when midwives and similar birthing attendants are involved. This Article is the first to fully explore the unique skillset of traditional birth attendants (TBAs). …

Department of Otolaryngology (ENT) Faculty Publications

[Introduction] Chronic rhinosinusitis with nasal polyps (CRSwNP) can substantially affect quality of life (QoL), and is often challenging to manage.¹ First-line treatment for the management of CRSwNP involves intranasal corticosteroids, with short courses of systemic corticosteroids (SCS) for exacerbations, and sinus surgery for uncontrolled disease.² Biologics targeting type 2 inflammation (eg, dupilumab, omalizumab, and mepolizumab) have become a treatment option for refractory CRSwNP. With the advent of disease-modifying treatments such as biologics, control, defined as patients reporting no/low-symptom levels, has increasingly become the treatment goal for CRSwNP.³ However, the optimal use of biologics for symptom control in individual patients remains …

Computer Science Faculty Research and Publications

Delirium occurs in about 80% of cases in the Intensive Care Unit (ICU) and is associated with an extended hospital stay, increased mortality, and other complications. Delirium lacks biomarker-based diagnosis and is frequently treated with antipsychotic drugs (APD), despite numerous studies debating its efficacy. Since randomized controlled trials (RCT) are expensive and time-consuming, we approach the research question of estimating the efficacy and safety outcomes of APD in treating delirium through retrospective cohort analysis. We employed the Causal inference framework to explore the underlying causal model for Delirium patient cohort. We focus on building a structural causal model for delirium …

It also explores how education serves as a stepping stone from childhood curiosity to a lifetime …


Reflections On The Importance Of Critical Theory To Teaching Environmental Law, Sean M. Kammer Jan 2025

Reflections On The Importance Of Critical Theory To Teaching Environmental Law, Sean M. Kammer

South Dakota Law Review

The freedom of students to learn about critical approaches to understanding their world is under sustained political attack. In this time of increasing environmental peril and political dysfunction, Professor Sean M. Kammer reflects upon the importance of critical theory (including Critical Race Theory) to understanding - and ultimately redressing - the related problems of resource scarcity and environmental degradation. While these problems can surely be described in terms of "economic inefficiencies" or "ecological disturbances," as they most often are, they must also be understood (and taught) as problems of colonial exploitation and violence. For example, one cannot understand Justice John …

Sugar Maple (Acer Saccharum Marsh.) Tree-Ring Growth And Carbon Stable Isotope Responses To Nitrogen And Climate, Libbie Ring

Dissertations, Master's Theses and Master's Reports

This dendrochronological and stable carbon isotope study used tree rings from sugar maple (Acer Saccharum Marsh.) collected at long-term nitrogen (N) amended sites throughout Michigan to understand N amendment and deposition, climate, and growth relationships. Climate responses varied by site, however, we found importance in grouping sites by “productivity” which is related to inherent N and soil nutrients. Our results did not detect an overall effect of N amendments on growth during the treatment period. However, data shows N amendments benefiting larger diameter trees, while smaller diameter trees responded more positively without amendments, especially on more productive sites. Results …

Methods In Statistics, Machine Learning, And Deep Learning For Combining Multi-Omics Dataset, Md Mutasim Billah

Dissertations, Master's Theses and Master's Reports

Transcriptome-wide association studies (TWAS) have emerged as a powerful strategy to bridge genome-wide association studies (GWAS) with gene regulatory mechanisms by integrating genotypic data with gene expression data. While early TWAS methods typically rely on linear models and single-tissue expression references, recent advances underscore the need for flexible, multi-tissue approaches that can capture heterogeneous regulatory architectures and tissue-specific expression patterns. This dissertation introduces a three‑part research project that advances multi‑tissue transcriptome‑wide association studies (TWAS) along complementary axes of methodology, statistical power, and modelling flexibility.

In chapter One, TWAS‑CTL introduces a two‑stage cross‑tissue learner that trains any user‑chosen single‑tissue imputers (STLs) …


Effects Of Invigorating And Relaxing Music On Heart Rate, Blood Pressure, And Heart Rate Variability, Matthew Joshua Faur Jan 2025

Effects Of Invigorating And Relaxing Music On Heart Rate, Blood Pressure, And Heart Rate Variability, Matthew Joshua Faur

Honors Undergraduate Theses

Heart-rate variability (HRV) has been documented to correlate with several health measures, including autonomic nervous system longevity and athletic performance (Zulfiqar, 2010). While increasing age does not affect heart rate, there is a steady decline in HRV, which is a biological marker of aging and the decline of autonomic nervous system function. Furthermore, men who exercise regularly tend to have increased HRV, suggesting a mitigation of the typical age-dependent loss of HRV (Kristal-Boneh et al., 1995). Previous studies have suggested that music may have a physiological effect (e.g., fluctuating vitals, emotional changes) on cardiovascular parameters. However, little is known about …

Respiratory Cycle Influence On Lumbosacral Muscle Function: A Tensiomyographic Analysis, Anthony Trombetta

Honors Undergraduate Theses

Introduction:

Tensiomyography (TMG) has significant potential in examining muscle functionality while evading the limitations found in other methods muscle analysis. Specifically, the erector spinae and other lumbosacral muscles can be analyzed with little challenge. Such analyses include data on muscle displacement (Dm), delay time (Td), contraction time (Tc), half-relaxation time (Tr), and sustain time (Ts). Of these parameters, the most evaluated and with the highest level of reliability are Dm, Td, and Tc. However, stiffness of the lumbar spine and lumbosacral muscles fluctuates throughout the respiratory cycle. These fluctuations may pose an issue when examining the functionality of muscles. This …

Impact Of Tgf-Β And Twist1 On Motility And Proliferation In Estradiol-Treated Mcf-7 Tamr Cells In-Vitro, Thomas L. Scott Iii

Honors Undergraduate Theses

Breast cancer is a highly malignant cancer and is known to be grouped into three main types: adenocarcinoma, invasive ductal carcinoma (IDC) and ductal carcinoma. Breast cancer commonly arises as adenocarcinoma, located in the milk ducts, and becomes IDC when it spreads into the surrounding tissue from the influence of cytokines and hormones. This study outlines the rate of proliferation and motility of a type of adenocarcinoma, MCF-7-TamR, to become invasive ductal carcinoma when Twist1 is downregulated and exposed to TGF- and estradiol (E2) in-vitro. We hypothesize that the downregulation of Twist1 will reduce cell adhesion and cytoskeleton proteins …


Tools And Trends: An Analysis Of Maya Dental Modification, Channing M. Cook Jan 2025

Tools And Trends: An Analysis Of Maya Dental Modification, Channing M. Cook

Honors Undergraduate Theses

The ancient Maya practiced dental modification, intentionally filing, incising, and inlaying stones into the front teeth, potentially to display identity and status. The literature surrounding Maya dental modification tends to overlook mechanical aspects of the process, and many studies approach dental modification through limiting or destructive means. Optical microscopy presents an adaptable, cost-effective option for closer inquiry. Preliminary research suggests the process of dental modification leaves distinct patterns of tool use, depending on style, that can be identified through optical microscopy. The sample selected includes 25 incisors and canines from 14 Classic period Maya individuals from Altun Ha, representing 12 …

Investigating The Role Of Prostasin In Angiogenesis: A Chorioallantoic Membrane Model Approach, Zaima Aline Jan 2025

Investigating The Role Of Prostasin In Angiogenesis: A Chorioallantoic Membrane Model Approach, Zaima Aline

Honors Undergraduate Theses

Prostasin, also known as PRSS8 or CAP1, is a glycosylphosphatidylinositol (GPI)-anchored extracellular serine protease involved in various physiological and pathophysiological processes. Prostasin expression is observed during key phases of trophoblast invasion and placental development, critical steps in embryo implantation in Rhesus monkeys. This suggests a role for prostasin in extracellular matrix remodeling and tissue invasion, both essential for a healthy pregnancy. Moreover, prostasin appears vital for development as studies in mice show that a germline knockout of the gene leads to significant placental defects and eventual embryonic death, highlighting its importance in vascular and structural development within the placenta.
