Combined methylmalonic acidemia and homocystinuria (cblC) is the most common inborn error of intracellular cobalamin metabolism and due to mutations in Methylmalonic Aciduria type C and Homocystinuria (MMACHC). Recently, mutations in the transcriptional regulators HCFC1 and RONIN (THAP11) were shown to result in cellular phenocopies of cblC. Since HCFC1/RONIN jointly regulate MMACHC, patients with mutations in these factors suffer from reduced MMACHC expression and exhibit a cblC-like disease. However, additional de-regulated genes and the resulting pathophysiology is unknown. Therefore, we have generated mouse models of this disease. In addition to exhibiting loss of Mmachc, metabolic perturbations, and developmental defects previously …

Secretogranin Iii Stringently Regulates Pathological But Not Physiological Angiogenesis In Oxygen-Induced Retinopathy, Chang Dai, Prabuddha Waduge, Liyang Ji, Chengchi Huang, Ye He, Hong Tian, Elizabeth Zuniga-Sanchez, Amit Bhatt, Iok-Hou Pang, Guanfang Su, Keith A Webster, Wei Li

Faculty, Staff and Students Publications

Conventional angiogenic factors, such as vascular endothelial growth factor (VEGF), regulate both pathological and physiological angiogenesis indiscriminately, and their inhibitors may elicit adverse side effects. Secretogranin III (Scg3) was recently reported to be a diabetes-restricted VEGF-independent angiogenic factor, but the disease selectivity of Scg3 in retinopathy of prematurity (ROP), a retinal disease in preterm infants with concurrent pathological and physiological angiogenesis, was not defined. Here, using oxygen-induced retinopathy (OIR) mice, a surrogate model of ROP, we quantified an exclusive binding of Scg3 to diseased versus healthy developing neovessels that contrasted sharply with the ubiquitous binding of VEGF. Functional immunohistochemistry visualized …

Magnetic Nanoparticles Enhanced Surface Plasmon Resonance Biosensor For Rapid Detection Of Salmonella Typhimurium In Romaine Lettuce, Devendra Bhandari, Fur-Chi Chen, Roger C. Bridgman

Human Sciences Faculty Research

Salmonella is one of the major foodborne pathogens responsible for many cases of illnesses, hospitalizations and deaths worldwide. Although different methods are available to timely detect Salmonella in foods, surface plasmon resonance (SPR) has the benefit of real-time detection with a high sensitivity and specificity. The purpose of this study was to develop an SPR method in conjunction with magnetic nanoparticles (MNPs) for the rapid detection of Salmonella Typhimurium. The assay utilizes a pair of well-characterized, flagellin-specific monoclonal antibodies; one is immobilized on the sensor surface and the other is coupled to the MNPs. Samples of romaine lettuce contaminated with …

Do Empowered Women Receive Better Quality Antenatal Care In Pakistan? An Analysis Of Demographic And Health Survey Data, Muhammad Asim, Waqas Hameed, Sarah Saleem

Community Health Sciences

Introduction: Quality antenatal care is a window of opportunity for improving maternal and neonatal outcomes. Numerous studies have shown a positive effect of women empowerment on improved coverage of maternal and reproductive health services, including antenatal care (ANC). However, there is scarce evidence on the association between women's empowerment and improved ANC services both in terms of coverage and quality. Addressing this gap, this paper examines the relationship between multi-dimensional measures of women empowerment on utilization of quality ANC (service coverage and consultation) in Pakistan.
Methods: We used Pakistan Demographic and Health Survey 2017-18 (PDHS) data which comprises of 6,602 …

Comparison Of Percutaneous Vs Oral Infection Of Hamsters With The Hookworm Ancylostoma Ceylanicum: Parasite Development, Pathology And Primary Immune Response, Richard D. Bungiro, Lisa M. Harrison, Blaise Dondji, Michael Cappello

Biology Faculty Scholarship

Background

Hundreds of millions of people in poor countries continue to suffer from disease caused by bloodfeeding hookworms. While mice and rats are not reliably permissive hosts for any human hookworm species, adult Golden Syrian hamsters are fully permissive for the human and animal pathogen Ancylostoma ceylanicum. Similar to humans, hamsters may be infected with A. ceylanicum third-stage larvae orally or percutaneously. Oral infection typically leads to consistent worm yields in hamsters but may not accurately reflect the clinical and immunological manifestations of human infection resulting from skin penetration.

Methodology/Principal findings

In this study we compared host responses …

Covid-19 Challenges And Firm Responses: Analysis Of A City-Wide Census In A Developing Country, Bryan S. Weber, Toan Luu Duc Huynh

Publications and Research

We use the unique data set of 16,300 firms' responses for the large‐scale census survey in an urban area at Ho Chi Minh City (Vietnam) to study how firms perceived their problems and responded to during the COVID‐19 pandemic. We provide estimates of 65 cross‐associations between a firm's challenges during the pandemic and their responses. We find several firm characteristics that suggest increased likelihood of pandemic response, including some, such as state ownership, which are typically associated with being slow to respond to market conditions. A theoretical model is posited that matches with the rapidly declared survey response.

Turning The Tables On Covid-19, Wei Wei

Rosen Research Review

The COVID-19 pandemic all but eviscerated the restaurant industry. Around the world, businesses shut doors. For some this would prove to be forever, and those that did reopen were stifled by strict social-distancing regulations and the challenge of how best to rearrange their servicescapes to meet regulations and still provide an enjoyable dining experience. The big question: how best to do this? Dr. Wei Wei from UCF Rosen College of Hospitality Management and her collaborators examined the issues of built density and customer power to uncover a vital piece of the puzzle.

Essential Worker Heroes, Cynthia Mejia

Rosen Research Review

The COVID-19 pandemic brought with it untold disruptions to the hospitality and related services industries, and it also prompted a dramatic shift in public perceptions towards line-level workers. Normally associated with unskilled and ‘dirty’ labor, these workers were embraced as ‘heroes’ by providing essential services in the face of a severe and frightening public health threat. This phenomenon provided a rare opportunity for researchers in the fields of hospitality and psychology to examine how those workers, and the society they served, made sense of this perceptive shift.

Restaurants Post Covid-19, Elizabeth Yost, Murat Kizildag, Jorge Ridderstaat

Rosen Research Review

When you’re suddenly forced to close 1,800 restaurant dining rooms without any certainty of being able to reopen them any time soon, you need to act decisively and prioritize if you plan to be around for a grand reopening. For Darden Restaurants and their market-leading US brands, those priorities during lockdown were ‘look after the people – look after the cash!’ Dr. Elizabeth Yost, Dr. Murat Kizildag and Dr. Jorge Ridderstaat of UCF Rosen College of Hospitality Management investigate the company’s achievement.

The Impact Of Covid-19 On Restaurant Workers, Diego Bufquin, Jeong-Yeol Park, Robin Back

Rosen Research Review

The COVID-19 pandemic has hit many business sectors hard, none more so than the hospitality industry. Restaurant employees were already known to report high levels of depression and anxiety, as well as alcohol and drug use. How has the pandemic contributed to these problems? In the first study of its kind, Dr. Diego Bufquin, Dr. Jeong-Yeol Park and Dr. Robin Back from UCF Rosen College of Hospitality Management, along with two collaborators, examine the relationships between restaurant employees’ work status, mental health, substance use, and career turnover intentions during the pandemic.

Endothelial Nitric Oxide Synthase (Enos) And The Cardiovascular System: In Physiology And In Disease States, N Tran, T Garcia, M Aniqa, S Ali, A Ally, Surya M. Nauli

Pharmacy Faculty Articles and Research

Endothelial nitric oxide synthase (eNOS) plays a critical role in regulating and maintaining a healthy cardiovascular system. The importance of eNOS can be emphasized from the genetic polymorphisms of the eNOS gene, uncoupling of eNOS dimerization, and its numerous signaling regulations. The activity of eNOS on the cardiac myocytes, vasculature, and the central nervous system are discussed. The effects of eNOS on the sympathetic autonomic nervous system (SANS) and the parasympathetic autonomic nervous system (PANS), both of which profoundly influence the cardiovascular system, will be elaborated. The relationship between the eNOS protein with cardiovascular autonomic reflexes such as the baroreflex …

Faculty, Staff and Students Publications

Thrombopoietin receptor agonists (TPO-RAs) can mitigate preprocedural thrombocytopenia in patients with chronic liver disease (CLD) however their effects on procedural outcomes is unclear. In this meta-analysis, we aimed to better define the efficacy, thrombotic risk and bleeding mitigation associated with the use of preoperative TPO-RAs in patients with CLD. We performed a systematic review and meta-analysis of randomized placebo-controlled clinical trials to assess the use of preprocedural TPO-RAs in patients with CLD, searching MEDLINE, EMBASE and the Cochrane library database. Six publications comprising eight randomized trials (1229 patients; 717 received TPO-RAs, 512 received placebo) and three unique TPO-RAs were retrieved. …

Current And Novel Neuroregenerative Therapies, Arrin Brooks

Theses, Dissertations and Capstones

Underlying the physical and cognitive deficits consequent of many neuropathologies is one common factor, the loss of neurons. While neurodegenerative diseases, stroke, and traumatic brain injury arise from a variety of etiologies, they all ultimately result in injury and/or death of neuronal cells and concomitant functional deficits. In the present work we primarily focus on current and potential treatments for localized lesions, particularly those in the striatum of Parkinson’s disease (PD) or the cortex as in stroke. First, we discuss a new surgical technique for deep brain stimulator (DBS) placement, as DBS is a mainstay treatment for movement disorders including …

Experiences In Remote Learning: Perceptions Of West Virginia Educators During The Covid-19 Pandemic, Craig Edward Arch

Theses, Dissertations and Capstones

In March 2020, the threat of illness caused by Covid-19 prompted West Virginia Governor Jim Justice to abruptly close public schools statewide. Instruction was delivered remotely for the remainder of the 2019 – 2020 school year and sporadically across the state during the 2020-2021 school year with educators holding class meetings and delivering instruction where technology and a reliable internet connection were available. Gaining understanding as it relates to a teacher’s remote learning experience may provide insight into how administrators can prepare for future interruptions in in-person instruction. Identifying specific areas teachers felt were challenging or stressful may provide a …

Improving Nutrition Literacy In Primary Care, Kami D. Dykes

DNP Research Projects

Abstract

By the year 2030, nearly one in every two adults will have obesity (Body Mass Index [BMI] ≥30 kg/m².), and one in four adults will have severe obesity (BMI ≥35 kg/m²) (Ward et al., 2019). Equally troubling is that obesity poses a threat to the health of individuals, decreases the quality of life, shortens life expectancy, causes and worsens comorbidities, and increases all- cause mortality (Abdelaal et al., 2017). Studies have shown a link between BMI, nutritional knowledge, and dietary practices. Nutrition literacy is a newer term that refers to the complex relationship between nutrition …

Causal Attribution, Personal Responsibility, And Regret In Lung Cancer Survivors, Justin Ulland, Anthony Cortez-Morales, Kevin R. Criswell

2022 Symposium

Introduction: Lung cancer is the second-most common cancer for males and females and the leading cause of cancer-related deaths in the United States. Ninety percent of lung cancer cases are associated with a smoking history. Less is known about (a) how lung cancer survivors with and without smoking histories attribute their cancer to secondhand smoke and (b) how those attributions may be associated with personal responsibility, regret, and stigma from medical staff/professionals. This secondary data analytic study examined 196 lung cancer survivors.

Method: Paper surveys included (a) whether secondhand smoking caused their cancer, (b) whether they perceived control …

Heart In Polycystic Kidney Disease Is Characterized By Cardiac Dysfunction And Structural Deformation, Farideh Amirrad

Pharmaceutical Sciences (PhD) Dissertations

Background: Autosomal dominant polycystic kidney disease (PKD) is a hereditary disorder affecting multiple organs, including the heart. PKD patients have been associated with arrhythmogenic remodeling in some clinical evaluations. However, the structural changes in myocardium and pathway analyses on the pathology of human PKD hearts have never been studied.

Methods: Sex- and age-matched human heart tissues from non-PKD and PKD were studied and verified in a heart-specific PKD mouse model. Structural and functional abnormalities of cardiac tissues and fibrosis-associated pathways were analyzed.

Results: Human PKD myocardium were infiltrated by inflammatory cells M1 and M2. Expressions of transforming growth factor (TGF-β …

Diabetes Mellitus Among Black/African Americans: A Critical Discourse Analysis Of Epigenetic Research, Eliana Jacobs

Honors Undergraduate Theses

During their lifetime, Black/African Americans have a higher likelihood of developing the diabetes mellitus metabolic disorder than other racial and ethnic groups in the United States. While research indicates that socioeconomic status, diet, and obesity factor into race disparities, the epigenetics field additionally identifies historical and contemporary racism as contributors to race disparities. This study is a qualitative analysis that examines a sample of health science research articles that use an epigenetics approach to understand diabetes among Black/African Americans. I analyzed the extent and mechanisms through which articles subtly reproduce dominant stereotypes of Black/African Americans and diabetes through representations of …

A Retrospective Analysis Of Ebola Virus Disease In Liberia, Matthew Jeremiah Matson

Theses, Dissertations and Capstones

The outbreak of Ebola virus disease (EVD) centered in the West African countries of Guinea, Liberia, and Sierra Leone from 2013-2016 was the longest and largest such outbreak on record. At least 30,000 cases were reported, and the outbreak lasted nearly two-and-a-half years. Despite the progress made during and since that time, many questions remain unanswered. The studies here utilize a large set of nearly 750 whole blood samples from patients that were triaged and treated at the ELWA-3 Ebola treatment unit in Monrovia, Liberia in 2014 and 2015. Viral load, as approximated by qRT-PCR diagnostic assays in the field, …
