Central Neural Mechanisms Of Salt-Sensitive Hypertension, Robert Larson
Central Neural Mechanisms Of Salt-Sensitive Hypertension, Robert Larson
Dissertations, Master's Theses and Master's Reports
Hypertension (HTN) is a major risk factor for the development of cardiovascular disease, and it’s estimated that over 80 million adults in the United States have HTN. Essential HTN often demonstrates sensitivity to salt, and reductions in dietary salt attenuate high blood pressure in this population. Evidence indicates that the paraventricular nucleus (PVN) of the hypothalamus is a key driver of HTN due to excess salt intake. The cellular mechanisms whereby PVN neuronal activity is augmented in response to salt are largely unknown. Previous work from our lab has demonstrated that small conductance calcium activated potassium (SK) channel function is …
Vena Cava Filter Utilization And Retrieval: A Quality Of Care Issue, Joshua Brown
Vena Cava Filter Utilization And Retrieval: A Quality Of Care Issue, Joshua Brown
Theses and Dissertations--Pharmacy
Vena cava filters (VCFs) are mechanical devices implanted in the inferior vena cava to trap thrombi from travelling to the pulmonary circulation, resulting in pulmonary embolism. VCFs are available as permanent or non-permanent, retrievable devices and are generally indicated for use in patients unable to receive systemic anticoagulation or at exceedingly high risk for pulmonary embolism (PE). Retrievable devices allow for removal of the VCF once the contraindication to anticoagulation or high risk of PE has abated. Since the introduction of retrievable VCFs in the early 2000’s, use of VCFs has increased three-fold, with >85% of all VCFs placed being …
Probing Allosteric, Partial Inhibition Of Thrombin Using Novel Anticoagulants, Stephen S. Verespy Iii
Probing Allosteric, Partial Inhibition Of Thrombin Using Novel Anticoagulants, Stephen S. Verespy Iii
Theses and Dissertations
Thrombin is the key protease that regulates hemostasis; the delicate balance between procoagulation and anticoagulation of blood. In clotting disorders, like deep vein thrombosis or pulmonary embolism, procoagulation is up-regulated, but propagation of clotting can be inhibited with drugs targeting the proteases involved, like thrombin. Such drugs however, have serious side effects (e.g., excessive bleeding) and some require monitoring during the course of treatment. The reason for these side effects is the mechanism by which the drugs’ act. The two major mechanisms are direct orthosteric and indirect allosteric inhibition, which will completely abolish the protease’s activity. Herein we sought an …
Exploring The Role Of Intersectionality On Cardiovascular Disease Risk In Sexual Minorities, Leia Harper
Exploring The Role Of Intersectionality On Cardiovascular Disease Risk In Sexual Minorities, Leia Harper
Theses and Dissertations
Background: Previous research has shown that sexual minority individuals (SM) are twice as likely to smoke, twice as likely to be overweight or obese, and less likely to be physically active than heterosexual persons; all of which place SMs at an increased risk for cardiovascular disease (CVD). While information on CVD risk by race/ethnicity and socioeconomic status is well documented, there is scant literature examining race, gender, and the potential CVD risk in SMs. The purpose of this study was to examine CVD risk in sexual minorities.
Method: The current study used data from the National Longitudinal Study of Adolescent …
Ppap2b Expression Limits Lesion Formation In Murine Models Of Atherosclerosis, Paul A. Mueller
Ppap2b Expression Limits Lesion Formation In Murine Models Of Atherosclerosis, Paul A. Mueller
Theses and Dissertations--Physiology
Coronary artery disease (CAD) is the leading cause of death in both men and women worldwide and is defined as a narrowing of the coronary arteries due to accumulation of atherosclerotic plaques. Genome-wide association studies have identified risk loci within the gene PPAP2B that confers increased risk of developing CAD. Evidence suggests these aforementioned SNPs are regulating PPAP2B expression in a cis-manner through the interruption of transcription factor binding sites. PPAP2B encodes the lipid phosphate phosphatase 3 enzyme that plays a key role in degrading bioactive lysophosphatidic acid (LPA). LPA has a plethora of effects on vascular tissue and is …
Development And Application Of Gadolinium Free Cardiac Magnetic Resonance Fibrosis Imaging For Multiscale Study Of Heart Failure In Patients With End Stage Renal Disease, Tori A. Stromp
Theses and Dissertations--Physiology
Cardiac magnetic resonance (CMR) is a powerful tool to noninvasively image ventricular fibrosis. Late gadolinium enhancement (LGE) CMR identifies focal and, with T1 mapping, diffuse fibrosis. Despite prevalent cardiac fibrosis and heart failure, patients with end stage renal disease (ESRD) are excluded from LGE. Absence of a suitable diagnostic has limited the understanding of heart failure and obstructed development of therapies in the setting of ESRD. A quantitative, gadolinium free fibrosis detection method could overcome this critical barrier, propelling the advancement of diagnostic, monitoring, and therapy options. This project describes the development of a gadolinium free CMR technique and application …
Lifestyle Contributors To Cardiovascular Disease Risk, Adam J. Berrones
Lifestyle Contributors To Cardiovascular Disease Risk, Adam J. Berrones
Theses and Dissertations--Kinesiology and Health Promotion
Aortic stiffness is an independent risk factor that has prognostic value regarding future cardiovascular disease (CVD) events such as myocardial infarction, strokes, and heart failure. Although death rates due to coronary heart disease have declined in recent years, the leading global killer remains CVD and prevalence is still high. Understanding lifestyle contributors associated with aortic stiffness would provide the public with insight into targeting key health-related behaviors.
The purpose of this observational study was to examine the association of physical activity, physical function, and dietary quality as independent factors contributing to aortic stiffness in apparently healthy middle aged men. Fifty-two …
The Role Of Pxr And Ikkβ Signaling In Cardiometabolic Disease, Robert N. Helsley
The Role Of Pxr And Ikkβ Signaling In Cardiometabolic Disease, Robert N. Helsley
Theses and Dissertations--Pharmacology and Nutritional Sciences
Cardiovascular disease (CVD) is the leading cause of death worldwide and is partially attributed to perturbations in lipid metabolism. Xenobiotics, such as pharmaceutical drugs and environmental chemicals, have been associated with increased risk of CVD in multiple large-scale human population studies, but the underlying mechanisms remain poorly defined. We and others have identified several xenobiotics as potent agonists for the pregnane X receptor (PXR), a nuclear receptor that can be activated by numerous drugs as well as environmental and dietary chemicals. However, the role of PXR in mediating the pathophysiological effects of xenobiotic exposure in humans and animals remains elusive. …
Molecular Basis Of Sex Differences In Cardiac Hypertrophy And Heart Failure, Maya James
Molecular Basis Of Sex Differences In Cardiac Hypertrophy And Heart Failure, Maya James
Online Theses and Dissertations
Transforming growth factor beta ligands and receptors are known to be pro-hypertrophic and pro-fibrotic factors in the heart, and are known to contribute to the development of cardiac hypertrophy and heart failure. It is well established that premenopausal females possess a lower incidence of these pathologies. We and others have observed a greater level of fibrosis in male hearts compared to female hearts in rodent models of cardiac hypertrophy. It is well established that estrogen is cardioprotective in that it can prevent the development of cardiac hypertrophy, as well as abrogate the development of heart failure following sustained cardiac hypertrophy. …
