The Functional Importance Of Methyl Cpg Binding Domain Proteins 2 And 3 In Regulating Fetal Hemoglobin Expression In Human Adult Erythroid Cells, Alexander Azzo

Theses and Dissertations

Humans undergo two developmental switches in the predominantly expressed β-like globin chain during embryogenesis and fetal development. The first switch from embryonic (ε) to fetal (γ) occurs around week 5 of embryonic development, while the second switch from fetal to adult (β) globin occurs shortly after birth. By adulthood, fetal hemoglobin represents only 1-2% of total hemoglobin in the blood. As sufficiently elevated levels of fetal hemoglobin are beneficial for improving clinical outcomes in sickle cell disease and β-thalassemia, the mechanisms that enforce silencing of fetal hemoglobin expression postnatally are of great clinical significance. The methyl-CpG binding domain protein MBD2 …

Accounting For The Uncertainty Due To Chemicals Below The Detection Limit In Mixture Analysis, Paul M. Hargarten

Theses and Dissertations

Humans are exposed to multiple chemicals every day. Epidemiological studies have shown that chemical mixtures are associated with cancers, allergies, neurodevelopmental disorders, and other adverse health effects. To assess these associations, investigators are increasingly using chemical mixture approaches like weighted quantile sum (WQS) regression. In these studies, the research objectives are to determine whether a mixture of correlated chemicals is associated with an adverse health outcome and to identify the important chemicals. However, as experimental equipment measures each exposure to a chemical-specific detection limit, the exposures are unknown between zero and the detection limit. Indeed, the number of exposures below …

Selenomonas Sputigena: Growth Conditions And Projected Virulence Factors Of An Emerging Oral Pathogen, Kayla A. Keller

Theses and Dissertations

Periodontal diseases are ubiquitous diseases. They can affect people through a chronic infection that happens over a lifetime, but also as an aggressive infection that afflicts the younger population. It not only results in tooth loss and a lower quality of life, but it can also lead to fatal secondary infections like cervical cancer, heart disease, and Alzheimer’s disease. This study looks at Selenomonas sputigena, an emerging oral pathogen, that has been hypothesized to contribute to periodontal disease. It has been linked to fatal septicemia and has been found in increased abundance within the oral biofilm during peak infection. …

Faculty, Staff and Students Publications

Background: During treatment for acute lymphoblastic leukemia (ALL), children report co-occurring symptoms of fatigue, sleep disturbance, pain, nausea, and depression as a symptom cluster. Central nervous system–directed ALL therapies also put children at risk for cognitive impairments. Cancer therapies can cause an increase in oxidative stress, which may contribute to treatment-related symptoms. This study examined the longitudinal relationships between biomarkers of oxidative stress in the cerebrospinal fluid, the Childhood Cancer Symptom Cluster–Leukemia (CCSC-L), and cognition, in children over the first year of ALL treatment. Methods: Glutathione (GSH) biomarkers of oxidative stress were measured in cerebrospinal fluid collected during treatment lumbar …

Prevalence Of Chronic Hepatitis B In Oro Province, Papua New Guinea, Alice Unah Lee, Luke Mair, Bob Kevin, Lily Gandi, Olive Tarumuri, Caroline Lee, Sue Huntley, David Carl Hilmers

Faculty, Staff and Students Publications

Chronic hepatitis B (CHB) affects over 250 million people worldwide. In Papua New Guinea, the prevalence of CHB has been estimated to be over 8%, and it is a leading cause of death. To address this problem, an alliance was formed between the government of Oro Province, a large private employer and an Australian nongovernmental organization, which established a CHB test and treatment programme. Between 2014 and 2019, rapid hepatitis B surface antigen testing was performed on 4068 individuals in Oro Province. The crude prevalence rate was 12.98% and was significantly higher in males (15.26%) than females (10.94%) (P < 0.001). The rate was 4.72% among children aged 10 years and under, 12.81% among women of childbearing age (19–35 years) and 18.48% among health-care workers. These results indicate that the rates of vaccination at birth and later among women of childbearing age and health-care workers must be improved to prevent transmission of CHB.

Department of Agronomy and Horticulture: Faculty Publications

The current COVID-19 pandemic has brought attention to challenges associated with our dominant industrial food system in the U.S. The general public now has more appreciation for farm workers and meatpacking employees, as well as those in grocery stores and in food transportation who are suddenly recognized as essential frontline workers. It apparently takes a crisis for us to focus clearly on the fragility of this system and the lives of people on whom we depend. In this commentary we discuss the definition of food sovereignty, how it manifests in urban areas, and how the COVID-19 pandemic can trigger viable …

The Impact Of Lifestyle Medicine On Nonalcoholic Fatty Liver Disease, Kelli L. Noble

DNP Research Projects

Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide. The main risk factor for the development of NAFLD is metabolic syndrome. Women are at greatest risk, typically in their 5th to 6th decade of life. The more aggressive form of NAFLD is nonalcoholic steatohepatitis (NASH) which is characterized by inflammation associated with NAFLD. NASH has the greatest tendency to progress into cirrhosis. However, lifestyle intervention has been shown to effectively treat, and even reverse NAFLD. The purpose of this quantitative, quasi-experimental study was to lend additional research and demonstrate improvement in NAFLD through lifestyle intervention with 1) …

Reducing Hypertension Through Faith Community Nursing, Michelle White

DNP Research Projects

Hypertension affects approximately 31.1% of adults (1.39 million) worldwide. It continues to be a significant risk factor for cardiovascular disease and strokes, the leading causes of death in the United States (Mills, Stefanescu, & He, 2020). Hypertension is expected to increase due to the aging population and unhealthy lifestyle choices of the American people (American Heart Association [AHA], 2018a). Therefore, effective strategies are required to manage hypertension in order to decrease stroke and cardiovascular events that can save the lives of many Americans. National programs such as Healthy People 2020 are working to achieve blood pressure control within the United …

Molecular Genetic Cancer Screening: Role Of Prediction Of Colorectal Disease In The Clinic Setting, Samantha Spinks

DNP Research Projects

Colorectal Cancer is the third most common cancer in men and women and the second leading cause of cancer related deaths (ACS, 2019). Colonoscopy screening can prevent colon cancer by early detection and removal of adenomatous colon polyps. The ACS has been lowered from age 50 to 45 due to an increase in the prevalence of colon cancer in people below the age of 50 years of age. Molecular genetic screening is a tool that providers can use to identify patients who are at risk for premature adenomas. People who have a genetic variant are more likely to develop adenomas …

Law, Structural Racism, And The Covid-19 Pandemic, Ruqaiijah Yearby, Seema Mohapatra

All Faculty Scholarship

Racial and ethnic minorities have always been the most impacted by pandemics because of: disparities in exposure to the virus; disparities in susceptibility to contracting the virus; and disparities in treatment. This article explains how structural racism, the ways in which laws are used to advantage the majority and disadvantage racial and ethnic minorities, has caused these disparities. Specifically, this article focuses on how employment, housing, health care, and COVID-19 relief laws have been manipulated to disadvantage racial and ethnic minorities, making minorities more susceptible to COVID-19 infection and death. This article uses Blumenshine’s 2008 framework to outline how structural …

Predictive Factors For Identifying Macrolide Responder In Treating Chronic Rhinosinusitis, Kachorn Seresirikachorn

Chulalongkorn University Theses and Dissertations (Chula ETD)

Background: A low-dose macrolide (LDM) has antineutrophilic activity, so they should not work for eosinophilic inflammation.

Characterization Of Bone Pathology In Sickle Cell Disease And Therapeutic Strategies, Mykel D. Green

Dissertations and Theses

Sickle cell disease (SCD) is a genetic hemoglobinopathy that has grown into a global health concern. While the advances in medical treatment and management of SCD during childhood have drastically improved the overall survival of children, the transition from pediatric to adult services is significantly inadequate in comparison. Life expectancies of patients with SCD in first world countries such as the United States are shortened to averages of 42 and 48 years for men and women, respectively. Despite the increasing number of people living with SCD, remarkably, few detailed studies have described the clinical course and complications of the disease …

Tunable Multiphase Dynamics Of Arginine And Lysine Liquid Condensates, Rachel S. Fisher, Shana Elbaum-Garfinkle

Advanced Science Research Center

Liquid phase separation into two or more coexisting phases has emerged as a new paradigm for understanding subcellular organization, prebiotic life, and the origins of disease. The design principles underlying biomolecular phase separation have the potential to drive the development of novel liquid-based organelles and therapeutics, however, an understanding of how individual molecules contribute to emergent material properties, and approaches to directly manipulate phase dynamics are lacking. Here, using microrheology, we demonstrate that droplets of poly-arginine coassembled with mono/polynucleotides have approximately 100 fold greater viscosity than comparable lysine droplets, both of which can be finer tuned by polymer length. We …
