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. …

Biopsychosocial Risk Factors And Knowledge Of Cervical Cancer Among Young Women: A Case Study From Kenya To Inform Hpv Prevention In Sub-Saharan Africa, Irene Ngune, Fatch Kalembo, Barbara Loessl, Lucy W. Kivuti-Bitok

Research outputs 2014 to 2021

Background Cervical cancer is the second most common female reproductive cancer after breast cancer with 84% of the cases in developing countries. A high uptake of human papilloma virus (HPV) vaccination and screening, and early diagnosis leads to a reduction of incidence and mortality rates. Yet uptake of screening is low in Sub-Saharan Africa and there is an increasing number of women presenting for treatment with advanced disease. Nine women in their twenties die from cervical cancer in Kenya every day. This paper presents the biopsychosocial risk factors that impact on cervical cancer knowledge among Kenyan women aged 15 to …

Comments On The Preliminary Framework For Equitable Allocation Of Covid-19 Vaccine, Ana Santos Rutschman, Julia Barnes-Weise, Robert Gatter, Timothy L. Wiemken

All Faculty Scholarship

On September 1, 2020 the National Academies released a draft framework for Equitable Allocation of a COVID-19 Vaccine. In this response, we analyze the proposed framework and highlight several areas.

Among the proposed changes, we highlight the need for the following interventions. The final framework for distribution of COVID-19 vaccines should give a higher priority to populations made most vulnerable by the social determinants of health. It should incorporate more geography-based approaches in at least some of the four proposed phases of vaccine distribution. It should address the possibility of a vaccine being made available through an emergency use authorization …

Mucosa-Associated Microbiota In Barrett’S Esophagus, Dysplasia, And Esophageal Adenocarcinoma Differ Similarly Compared With Healthy Controls, Shajan Peter, Amanda Pendergraft,, William Vanderpol, Mel Wilcox, Kondal R. Kyanam Kabir Baig, Casey Morrow, Jacques Izard, Peter J. Mannon

Department of Food Science and Technology: Faculty Publications

Introduction: Alterations in the composition of the human gut microbiome and its metabolites have been linked to gut epithelial neoplasia. We hypothesized that differences in mucosa-adherent Barrett’s microbiota could link to risk factors, providing risk of progression to neoplasia.

Methods: Paired biopsies from both diseased and nonaffected esophagus (as well as gastric cardia and gastric juice for comparison) from patients with intestinal metaplasia (n = 10), low grade dysplasia (n = 10), high grade dysplasia (n = 10), esophageal adenocarcinoma (n = 12), and controls (n = 10) were processed for mucosa-associated bacteria …

Urban Food Sovereignty: Urgent Need For Agroecology And Systems Thinking In A Post-Covid-19 Future, Ali Loker, Charles A. Francis

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 …

Functional Characterisation Of Cancer-Associated Fibroblasts From Nasopharyngeal Carcinoma, Wee Lin Wong

Student Works (2020-2029)

Nasopharyngeal carcinoma (NPC) remains a major health issue in Southern China and Southeast Asia where the disease is endemic. Whilst the cure rate for early stage NPC is high, patients often present with late stage diseases and have a 5-year survival rate of less than 50%. NPC patients often suffer from severe treatment side effects because of the location of the tumours that is in proximity to various important organs in the head and neck region. Therefore, alternative therapeutic approaches are needed to improve the treatment outcomes and reduce patient morbidity. Targeted therapies are not in routine use to treat …

Utilization Of A Continuous Pericapsular Nerve Group (Peng) Block With An Opioid-Sparing Repair Of A Femoral Neck Fracture In A Pediatric Patient, Karla Wyatt, Moustafa Zidane, Chyong-Jy Joyce Liu

Faculty, Staff and Students Publications

In the pediatric population, femoral neck fractures are usually associated with high-impact trauma and often present with pain in the groin area. Regional anesthesia can offer adjunctive therapy for acute pain management. Various techniques have been employed to circumvent pain related to hip fractures and resultant hip surgery. Neuraxial, lumbar plexus, caudal, epidural, fascia iliaca, and femoral continuous nerve block techniques are advantageous in mitigating hip pain. However, these approaches require patient repositioning during placement and carry the potential for motor blockade with resultant weakness. A newly described method, the Pericapsular Nerve Group (PENG) block, allows for analgesia of the …

Sirt3 Promotes Lipophagy And Chaperon-Mediated Autophagy To Protect Hepatocytes Against Lipotoxicity, Tian Zhang, Jingxin Liu, Shengnan Shen, Qiang Tong, Xiaojun Ma, Ligen Lin

Faculty, Staff and Students Publications

Lipophagy is a lysosomal lipolytic pathway that complements the actions of cytosolic neutral lipases. Chaperon-mediated autophagy (CMA) triggers lipid droplets (LDs) breakdown, to initiate lipolysis via either cytosolic lipases or macroautophagy. SIRT3, a mitochondrial NAD+-dependent deacetylase, regulates the acetylation status and activity of many substrates involving in energy metabolism. However, the role of SIRT3 in regulating lipophagy is controversial. The current study showed that SIRT3 expression was decreased and the macroautophagy flux was blocked in the primary hepatocytes from high-fat diet fed mice and P/O (palmitic acid and oleic acid mixture) treated AML12 mouse hepatocytes, compared with the corresponding controls. …

Extracellular Mitochondria Released From Traumatized Brains Induced Platelet Procoagulant Activity, Zilong Zhao, Yuan Zhou, Tristan Hilton, Fanjian Li, Cha Han, Li Liu, Hengjie Yuan, Ying Li, Xin Xu, Xiaoping Wu, Fangyi Zhang, Perumal Thiagarajan, Andrew Cap, Fu-Dong Shi, Jianning Zhang, Jing-Fei Dong

Faculty, Staff and Students Publications

Coagulopathy often develops soon after acute traumatic brain injury and its cause remains poorly understood. We have shown that injured brains release cellular microvesicles that disrupt the endothelial barrier and induce consumptive coagulopathy. Morphologically intact extracellular mitochondria accounted for 55.2% of these microvesicles, leading to the hypothesis that these extracellular mitochondria are metabolically active and serve as a source of oxidative stress that activates platelets and renders them procoagulant. In testing this hypothesis experimentally, we found that the extracellular mitochondria purified from brain trauma mice and those released from brains subjected to freeze-thaw injury remained metabolically active and produced reactive …

Lisinopril-Induced Angioedema In A Patient With Plasma Prekallikrein Deficiency, Swapan K Dasgupta, Stefanie Rivera, Perumal Thiagarajan

Faculty, Staff and Students Publications

Angiotensin-converting enzyme (ACE) inhibitors are extensively prescribed to treat patients with hypertension, congestive heart failure, and diabetic nephropathy. A small fraction of these patients (approximately 0.7%) develop angioedema, manifested by swelling of the lips and oropharynx. Angioedema of oropharynx is a medical emergency that can lead to asphyxiation and death. The angioedema is due to bradykinin generated from high molecular weight kininogen by kallikrein, which is derived from plasma prekallikrein by action of the factor XIIa, factor Xia, or prolylcarboxypeptidase. Bradykinin induces vasodilation and increased vascular permeability. ACE is the major degrading enzyme of bradykinin in the intravascular department. ACE …

Aromatase Inhibitors Plus Weight Loss Improves The Hormonal Profile Of Obese Hypogonadal Men Without Causing Major Side Effects, Georgia Colleluori, Rui Chen, Christie G Turin, Francesca Vigevano, Clifford Qualls, Biju Johnson, Sanjay Mediwala, Dennis T Villareal, Reina Armamento-Villareal

Faculty, Staff and Students Publications

Objective: In obese men, the increased expression of the aromatase enzyme in adipose tissue leads to high conversion of androgens to estrogens contributing to hypogonadotropic hypogonadism (HHG). Our objective is to evaluate efficacy and safety of weight loss (WL) plus aromatase inhibitor (AI) therapy in severely obese men with HHG. We hypothesize that AI+WL will be more effective as compared to WL alone in improving the hormonal profile, thus muscle strength and symptoms of HHG (primary outcomes), with no significant adverse effects on lean mass, metabolic profile, and bone mineral density (secondary outcomes).

Design: Randomized double-blind placebo-controlled pilot trial.

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 …

Structural Discrimination In Covid-19 Workplace Protections, Ruqaiijah Yearby, Seema Mohapatra

All Faculty Scholarship

Workers, who are being asked to risk their health by working outside their homes during the COVID-19 pandemic, need adequate hazard compensation, safe workplace conditions, and personal protective equipment (PPE). Sadly, this is not happening for many essential workers, such as those working in home health care and in the meat processing industry. These workers are not only being unnecessarily exposed to the virus, but they are also not receiving paid sick leave, unemployment benefits, and affordable health care and childcare. The lack of these protections is due to structural discrimination and has disproportionately disadvantaged women of color and low-wage …

The Problem With Relying On Profit-Driven Models To Produce Pandemic Drugs, Ana Santos Rutschman

All Faculty Scholarship

The longstanding problems of relying on a market response to a pandemic are becoming readily apparent in the United States, which has quickly become the epicenter of the COVID-19 outbreak. The problems are particularly pronounced in pharmaceutical markets, where we are pinning our hopes for both cures and vaccines. In previous work we have shown how characteristics of healthcare markets in the United States create a divergence between the private incentives of for-profit companies and public health needs, leading to sub-optimal health outcomes in what is a uniquely market-driven healthcare system. In this Essay, written as the COVID-19 pandemic unfolds, …

Substance Use Disorder, Discrimination, And The Cares Act: Using Disability Law To Strengthen New Protections, Kelly K. Dineen, Elizabeth Pendo

All Faculty Scholarship

The COVID-19 pandemic is having devastating consequences for people with substance use disorders (SUD). SUD is a chronic health condition—like people with other chronic health conditions, people with SUD experience periods of remission and periods of exacerbation and relapse. Unlike people with most other chronic conditions, people with SUD who experience a relapse may face criminal charges and incarceration. They are chronically disadvantaged by pervasive social stigma, discrimination, and structural inequities. People with SUD are also at higher risk for both contracting the SARS-CoV-19 virus and experiencing poorer outcomes. Meanwhile, there are early indications that pandemic conditions have led to …

Vaccine Hesitancy: Experimentalism As Regulatory Opportunity, Ana Santos Rutschman, Timothy L. Wiemken

All Faculty Scholarship

This symposium on patient innovation has prompted us to explore problems related to departures from official vaccination schedules. At a time in which vaccine confidence has been plummeting across the world, we argue that a more granular understanding—and ultimately a more finely tuned regulatory framework—is needed to reflect the current behavioral heterogeneity among indicated patients who choose to forego or delay administration of recommended vaccines. In particular, we focus on a phenomenon we term “vaccine staggering:” a departure from vaccination schedules in the form of delays in receiving one or more vaccines, which is motivated by the desire to boost …
