Environmental Regulation Of The Heart: The Role Of Non-Coding Rna And Epigenetics In Influencing Mitochondrial And Cellular Health, Quincy Alexander Hathaway

Graduate Theses, Dissertations, and Problem Reports (ETD)

The mitochondrion, a small but ubiquitously distributed organelle in the cell, continues to be the focus of many disease pathogeneses, tissue and organ dysfunctions, and other morbidities that occur throughout the body. The purpose of this work was to understand how cardiac mitochondrion are altered in disease and pathological states, specifically in their adaptation to environmentally stimulated regulatory networks, such as epigenetic modifications and promotion/inhibition of non-coding RNAs. Acute stress to mitochondrial regulation (inhalation toxicology) as well as chronic (type 2 diabetes mellitus) was examined. Using a FVB transgenic microRNA-378a mouse knockout model, the cardiovascular impact derived from altering the …

Diuretic And Natriuretic Activity Of Faah Inhibition In The Renal Medulla: A Proposed Role Of Palmitoylethanolamide And Its Regulation By Renal Medullary Interstitial Cells, Sara Dempsey

Theses and Dissertations

Hypertension is a critical public health issue worldwide, and in the United States, it is the leading cause of heart disease, stroke, and kidney failure, contributing to more than 1,100 deaths per day. It is proposed that the renal medulla combats increased blood pressure by releasing a neutral lipid from the lipid droplets of medullary interstitial cells, termed medullipin, which induces diuresis- natriuresis and vasodepression. The renal medulla is enriched with fatty acid lipid ethanolamides including the endocannabinoid anandamide (AEA), palmitoylethanolamide (PEA), and oleoylethanolamide (OEA), along with their primary hydrolyzing enzyme fatty acid amide hydrolase (FAAH). Our lab is investigating …

The Effects Of Habitual Protein Consumption On Vasodilation In Young Adults, Natalie O'Neal, Jordan Rezac

Health, Human Performance and Recreation Undergraduate Honors Theses

Introduction: Blood pressure is a critical indicator for a number of health risks and conditions, such as hypertension (high blood pressure), heart failure, and stroke. Decreasing blood pressure occurs by vasodilation (relaxation) of blood vessels. The consumption of high amounts of protein is hypothesized to have a correlation with the vasodilation of vessels, thus creating a decrease in blood pressure. Purpose: The purpose of this study was to relate blood vessel diameter to habitual protein consumption. Our findings have the power to make individuals more aware of the effect their habitual protein intake can have on cardiovascular health. Methods: This …

Cholesterol Metabolism And Statin Effects On An Fh Class Ii Ldl-Receptor Mutation., Linda Omer

Electronic Theses and Dissertations

Familial hypercholesterolemia (FH) is a common genetic disease and has been studied with the aim of finding a curative measure for decades. FH is caused by mutations in the low-density lipoprotein receptor (LDLR) resulting in defects in LDL-cholesterol (LDL-C)-receptor mediated endocytosis and development of premature cardiovascular disease (CVD). Here I describe the use of a corrected and non-corrected LDLR FH cell model to investigate receptor-mediated endocytosis and statin effects. For these studies, we reprogrammed FH fibroblast cells to induced pluripotent stem cells (iPSC) and confirmed their pluripotency and ability to differentiate to hepatocyte-like cells (HLC). A clustered regularly interspaced short …

OBJECTIVES: To assess the effect of pulmonary hypertension on neonatal intensive care unit mortality and hospital readmission through 1 year of corrected age in a large multicenter cohort of infants with severe bronchopulmonary dysplasia.

STUDY DESIGN: This was a multicenter, retrospective cohort study of 1677 infants bornChildren's Hospital Neonatal Consortium with records linked to the Pediatric Health Information System.

RESULTS: Pulmonary hypertension occurred in 370 out of 1677 (22%) infants. During the neonatal admission, pulmonary hypertension was associated with mortality (OR 3.15, 95% CI 2.10-4.73, P < .001), ventilator support at 36 weeks of postmenstrual age (60% vs 40%, P < .001), duration of ventilation (72 IQR 30-124 vs 41 IQR 17-74 days, P < .001), and higher respiratory severity score (3.6 IQR 0.4-7.0 vs 0.8 IQR 0.3-3.3, P < .001). At discharge, pulmonary hypertension was associated with tracheostomy (27% vs 9%, P < .001), supplemental oxygen use (84% vs 61%, P < .001), and tube feeds (80% vs 46%, P < .001). Through 1 year of corrected age, pulmonary hypertension was associated with increased frequency of readmission (incidence rate ratio [IRR] = 1.38, 95% CI 1.18-1.63, P < .001).

CONCLUSIONS: Infants with severe bronchopulmonary dysplasia-associated pulmonary hypertension have increased morbidity and mortality through …

The Roles Of Primary Cilia In Cardiovascular Diseases, Rajasekharreddy Pala, Maha Jamal, Qamar Alshammari, Surya M. Nauli

Pharmacy Faculty Articles and Research

Primary cilia are microtubule-based organelles found in most mammalian cell types. Cilia act as sensory organelles that transmit extracellular clues into intracellular signals for molecular and cellular responses. Biochemical and molecular defects in primary cilia are associated with a wide range of diseases, termed ciliopathies, with phenotypes ranging from polycystic kidney disease, liver disorders, mental retardation, and obesity to cardiovascular diseases. Primary cilia in vascular endothelia protrude into the lumen of blood vessels and function as molecular switches for calcium (Ca2+) and nitric oxide (NO) signaling. As mechanosensory organelles, endothelial cilia are involved in blood flow sensing. Dysfunction in endothelial …

Aims: There is debate about the optimum algorithm for cardiovascular disease (CVD) risk estimation. We conducted head-to-head comparisons of four algorithms recommended by primary prevention guidelines, before and after ‘recalibration’, a method that adapts risk algorithms to take account of differences in the risk characteristics of the populations being studied.

Methods & Results: Using individual-participant data on 360737 participants without CVD at baseline in 86 prospective studies from 22 countries, we compared the Framingham risk score (FRS), Systematic COronary Risk Evaluation (SCORE), pooled cohort equations (PCE), and Reynolds risk score (RRS). We calculated measures of risk discrimination and calibration, and …

Modeling In The Physiology Classroom, Sowmya Anjur

Faculty Publications & Research

Physiology and Disease is a Biology elective at IMSA that has been developed to be mostly student-centered. Some examples of student projects include modeling heart structure to reflect function and creating LED arduino monitors to measure heart rate. Students also measure their lung capacity and blood pressure to demonstrate correlation of these values with heart rate, and trace the correlation back to neuronal controls. Projects such as these integrate other disciplines such as engineering and conform to NGSS Science and Engineering standards and NGSS Cross cutting Concepts standards. Students take responsibility for their own learning and articulate better on tests.

Hyperhomocysteinemia As A Risk Factor For Vascular Contributions To Cognitive Impairment And Dementia, Brittani R. Price, Donna M. Wilcock, Erica M. Weekman

Physiology Faculty Publications

Behind only Alzheimer’s disease, vascular contributions to cognitive impairment and dementia (VCID) is the second most common cause of dementia, affecting roughly 10–40% of dementia patients. While there is no cure for VCID, several risk factors for VCID, such as diabetes, hypertension, and stroke, have been identified. Elevated plasma levels of homocysteine, termed hyperhomocysteinemia (HHcy), are a major, yet underrecognized, risk factor for VCID. B vitamin deficiency, which is the most common cause of HHcy, is common in the elderly. With B vitamin supplementation being a relatively safe and inexpensive therapeutic, the treatment of HHcy-induced VCID would seem straightforward; however, …

This descriptive, exploratory study, an extension of a previous analysis that examined high-priority problems in the first month, comprised 19 participants who were assigned to an intervention group that received a randomized, 12-week-pilot coping partnership (COPE-HF) intervention. A trained research nurse provided the intervention, and participants used a standard list to identify high-priority heart failure-related problems. Quantitative and content data analysis was conducted. While the highest-priority problem continued to be managing …

Myocardial Ischemia Reperfusion Injury: Apoptotic, Inflammatory And Oxidative Stress Role Of Galectin-3, Suhail Al-Salam, Satwat Hashmi

Department of Biological & Biomedical Sciences

Background/aims: Myocardial reperfusion has the potential to salvage the ischemic myocardium after a period of coronary occlusion. Reperfusion, however, can cause a wide spectrum of deleterious effects. Galectin-3 (GAL-3), a beta galactoside binding lectin, is closely associated with myocardial infarction (MI), myocardial fibrosis and heart failure. In our study, we investigated its role in ischemia-reperfusion injuries (IR) as this phenomenon is extremely relevant to the early intervention after acute MI.
Methods: C57B6/J wild type (WT) mice and GAL-3 knockout (KO) mice were used for murine model of IR injury in the heart where a period of 30 minutes ischemia was …
