Heparan sulfate proteoglycans (HSPGs) are potent regulators of vascular remodeling and repair. Heparanase is the major enzyme capable of degrading heparan sulfate in mammalian cells. Here we examined the role of heparanase in controlling arterial structure, mechanics, and remodeling. In vitro studies supported that heparanase expression in endothelial cells serves as a negative regulator of end...
Arterial thrombosis results from endovascular injury and, to a lesser extent, alterations in hemostatic equilibrium. Although multiple hereditary and acquired hemostatic risk factors have been described in the pathophysiology of venous thrombosis, the degree and type of abnormalities that contribute to arterial thrombosis are less well understood. Endothelial cell injury with the elaboration of...
Introduction: Child abuse has been defined as allowing others to cause physical, emotional, and sexual harm, and also physical and emotional pain to a child. The present study was a report on a case of physical and sexual child abuse accompanied by traumatic brain injury (TBI) referred to an emergency department.Case Presentation: A 4-year-old child was rushed into an emergency department...
conclusions major vascular injuries in our center occurred in young men, frequently because of stab wounds. popliteal injuries mostly caused by motor vehicle accidents was the second most common arterial injury, followed by combined ulnar and radial injuries. vascular reconstruction in the first hours after trauma may prevent many unnecessary and preventable amputation procedures. results most ...

BACKGROUND P-selectin blockade significantly inhibits inflammation and neointimal formation after arterial injury; however, the independent roles of platelet and endothelial P-selectins in this process are unknown. In atherosclerosis, both platelet and endothelial cell P-selectins are important. This study was designed to determine whether P-selectin expression on platelet, endothelial, or both...
OBJECTIVE The purpose of this study was to examine the anatomic distribution and associated mortality of combat-related vascular injuries comparing them to a contemporary civilian standard. DESIGN The Joint Trauma Theater Registry (JTTR) was queried to identify patients with major compressible arterial injury (CAI) and noncompressible arterial injury (NCAI) sites, and their outcomes, among ca...
Delivery of a heterogeneous population of cells with endothelial phenotype derived from peripheral blood has been shown to improve vascular responses after balloon arterial injury in an endothelium-dependent manner. Refinement of culture techniques has enabled the generation of outgrowth endothelial cells (OECs), a homogeneous population of distinctly endothelial cells expanded from circulating...
Chronic hyperinsulinemia is suspected of enhancing the development of arterial diseases. However, direct metabolic effects of insulin on the inner arterial wall are poorly documented. To assess the possible influence of variations in smooth muscle phenotype, we measured lipogenesis from glucose by rat thoracic aortas that had been injured with a balloon catheter. Aortas were exposed to insulin ...
