Arterial Distribution Of The Human Aorta: An Examination Of The Evolutionary, Developmental, And Physiological Bases Of Asymmetry., Brandon Oddo, Cooker Storm

Seaver College Research And Scholarly Achievement Symposium

The study of anatomy contends that “form follows function”; a disciplinary theme purporting that anatomical structures (i.e., cells, tissues, and organs) have a shape that serves its proper function. With this in mind, it is unclear why human arterial distribution off the aortic arch is asymmetrical, while the corresponding venous anatomy is symmetrical. We investigated the evolutionary, developmental, and physiological bases for the asymmetry of aortic arch branches in humans. First, we investigated the cardiovascular anatomy of ancestral species to determine if, and at what level, anatomical divergence (from aortic symmetry to asymmetry) occurs. Second, we examined the formation of …

Renal And Cardiovascular Morbidities Associated With Apol1 Status Among African-American And Non-African-American Children With Focal Segmental Glomerulosclerosis., Robert P. Woroniecki, Derek K.

BACKGROUND AND OBJECTIVES: African-American (AA) children with focal segmental glomerulosclerosis (FSGS) have later onset disease that progresses more rapidly than in non-AA children. It is unclear how APOL1 genotypes contribute to kidney disease risk, progression, and cardiovascular morbidity in children.

DESIGN SETTING PARTICIPANTS AND MEASUREMENTS: We examined the prevalence of APOL1 genotypes and associated cardiovascular phenotypes among children with FSGS in the Chronic Kidney Disease in Children (CKiD) study; an ongoing multicenter prospective cohort study of children aged 1-16 years with mild to moderate kidney disease.

RESULTS: A total of 140 AA children in the CKiD study were genotyped. High …

Assessment Of Obesity As A Cardiovascular Disease Risk Factor In A Geriatric Rural Texas Community - A Six Month Follow-Up, Alberto Coustasse Md, Mba

Alberto Coustasse, DrPH, MD, MBA, MPH

Coustasse, Alberto, Assessment of Obesity as a Cardiovascular Disease Risk Factor in a Geriatric Rural Texas Community – A Six Month Follow-up. Master of Public Health Track, Public Health Administration, December 1999, 22 pp., 9 tables, 9 illustrations, bibliography, 7 titles. The health fair approach was used as a method to establish individual and population health status baselines and to provide a mechanism to follow-up with an elderly population in a rural Texas community. A controlled trial sample of forty-four seniors was initially screened in a primary care clinic in August 1998. Patients were reevaluated at six months and results …

Role Of Cardiac Catecholamines In Embryos And Adults Under Stress, Candice Baker

Electronic Theses and Dissertations

Cardiovascular disease is responsible for the loss of one life every 38 seconds and accounts for 26.6 percent of all infants that die of congenital birth defects. Adrenergic hormones are critically important regulators of cardiovascular physiology in embryos and adults. They are key mediators of stress responses and have profound stimulatory effects on cardiovascular function, and dysregulation of adrenergic function has been associated with many adverse cardiac conditions, including congenital malformations, arrhythmias, ischemic heart disease, heart failure, and sudden cardiac death. Despite intensive study, the specific roles these hormones play in the developing heart is not well-understood. Further, there is …

Primary Cilia Regulates The Directional Migration And Barrier Integrity Of Endothelial Cells Through The Modulation Of Hsp27 Dependent Actin Cytoskeletal Organization, Thomas J. Jones, Ravi K. Adapala, Werner J. Geldenhuys, Chris Bursley, Wissam A. Aboualaiwi, Surya M. Nauli, Charles K. Thodeti

Pharmacy Faculty Articles and Research

Cilia are mechanosensing organelles that communicate extracellular signals into intracellular responses. Altered functions of primary cilia play a key role in the development of various diseases including polycystic kidney disease. Here, we show that endothelial cells from the oak ridge polycystic kidney (Tg737orpk/orpk) mouse, with impaired cilia assembly, exhibit a reduction in the actin stress fibers and focal adhesions compared to wild type. In contrast, endothelial cells from polycystin-1 deficient mice (pkd1null/null), with impaired cilia function, display robust stress fibers and focal adhesion assembly. We found that the Tg737orpk/orpk cells exhibit impaired directional migration and endothelial cell monolayer permeability compared …

Estimated Birth Weight And Adult Cardiovascular Risk Factors In A Developing Southern Chinese Population: A Cross Sectional Study, C. Mary Schooling, C. Q. Jiang, T. H. Lam, B. J. Cowling, S. L. Yeung, W. S. Zhang, K. K. Cheng, G. M. Leung

Publications and Research

Background: Birth weight is negatively associated with cardiovascular diseases and diabetes, but the associations are less well-established in developing populations where birth weight is often unavailable. We studied the association of birth weight and cardiovascular risk, using birth rank as an instrumental variable, in Southern China.

Methods: We used published data on birth weight by birth rank from an appropriate population and baseline data from the Guangzhou Biobank Cohort Study phases 2 & 3 (2005-8) to examine the adjusted associations, using instrumental variable analysis, of birth weight with clinically measured cardiovascular risk factors and the metabolic syndrome in older …

Hypertension In Autosomal Dominant Polycystic Kidney Disease: A Clinical And Basic Science Perspective, Shobha Ratnam, Surya M. Nauli

Pharmacy Faculty Articles and Research

Cardiovascular complications are major causes of morbidity and mortality in patients with autosomal dominant polycystic kidney disease (ADPKD). In particular, hypertension is insidious and remains a continuous problem that evolves during the course of the disease. Hypertension in ADPKD has been associated with abnormality in the renin-angiotensin-aldosterone system (RAAS). Early vascular changes have also been reported in young ADPKD patients. In addition, the cellular functions of mechanosensory cilia within vascular system have emerged recently. The basic and clinical perspectives of RAAS, vascular remodeling and sensory cilia are reviewed with regard to hypertension in ADPKD
