Detailed and comprehensive study at the molecular, cellular and pathophysiological levels are crucial to improving diagnosis and treatment of cardiovascular disease in children, and quite possibly hold the key to prevention in adults. Investigators seeks to identify mechanisms and risk factors associated with initiation and/or progression of cardiovascular disease in children, define differences and similarities between pediatric and adult disease mechanisms, and ultimately optimize therapies and strategies for prevention of heart disease.
Active collaborative projects with The Ohio State University include examination of the role of oxidants and mitochondria in sepsis-related cardiac failure, vascular endothelial growth factors (VEGF) transcript variation and angiogenesis, mechanisms of HIV-related cardiomyopathy and molecular approaches for antioxidant protection.
The Heart’s Response to Long-Term Exposure to Air Pollution
Air pollution studies have mostly focused on exposure durations that represent a portion of a lifespan. This animal model study suggests that long-term exposure to environmentally exposure to relevant concentrations of air pollutants are linked to symptoms consistent with beginning heart failure.

Investigating the Role of C-Reactive Protein in Development of Heart Diseases
Elevated plasma C-reactive protein (CRP) is a biomarker of cardiovascular diseases, but its potential roles as a participant of the disease process are not well defined. This study investigated the direct effects of CRP on human endothelial cells. Findings provide evidence supporting myocardial CRP as a locally produced inflammatory marker.

Examining the Role of the MKP1 Pathway in Cardiac Dysfunction During Endotoxemia
Myocardial tumour necrosis factor-α (TNF-α) expression induces cardiac dysfunction in endotoxemia. The aim of this study was to investigate the role of the MKP1 pathway in myocardial TNF-α expression and cardiac function during endotoxemia.

Direct and Indirect Effects of Particulate Matter on the Heart
Exposure to particulate matter causes a variety of responses on the cardiovascular system through both direct and indirect pathways. In this review, the authors present key evidence in both the direct and indirect pathways, suggest clinical applications of the current literature, and recommend directions for future research.

Abstract from Specialty Conference Selected for American Heart Association Presentation
Faculty members in the Center for Cardiovascular and Pulmonary Research, The Heart Center and The Ohio State University presented an abstract at the American Heart Association Basic Cardiovascular Sciences conference, which was selected to be re-presented at the 2010 American Heart Association conference.
The abstract “Subclinical Right Ventricular Remodeling in Restrictive Ventricular Septal Defect” was considered among the specialty conference’s top 10 percent of the accepted abstracts.
