AMP-activated kinase (AMPK) is a fuel-sensing enzyme present in most mammalian tissue. In response to a decrease in the energy state of a cell AMPK is phosphorylated and activated by still poorly characterized upstream events. Exposure of bovine aortic endothelial cells (BAEC) to chemically synthesized ONOO- acutely and significantly increased(More)
BACKGROUND Hormone replacement therapy increases intimal hyperplasia (IH) following vascular intervention. Matrix metalloproteinases (MMPs) play a role in IH development. We have shown estrogen up-regulates MT1-MMP expression, a transmembrane protein that activates MMP-2, and increases vascular smooth muscle cell (VSMC) collagen invasion via increased MMP-2(More)
Doppler ultrasonography sound-spectrum analysis (SSA) was used to evaluate blood flow in the transplanted kidney and its renal artery. Seven patients with posttransplant hypertension and a bruit over the transplanted kidney were screened for renal artery stenosis (RAS). In five patients, RAS was diagnosed by SSA, and in two it was not. These findings were(More)
OBJECTIVE The TransAtlantic Inter-Society Consensus (TASC) document did not define the best treatment for moderately severe iliac artery lesions, ie, TASC type B and type C iliac lesions, because of insufficient solid evidence to make firm recommendations. The purpose of this study was to evaluate the influence of risk factors on outcome of iliac stenting(More)
BACKGROUND Defining the phenotype is critical for investigating the genetic etiology of asthma. As part of the Collaborative Study on the Genetics of Asthma (CSGA), the primary objective of which is to identify asthma susceptibility loci, an algorithm was designed to determine diagnoses of definite asthma, probable asthma, less than probable asthma, or no(More)
INTRODUCTION Diabetes is known to increase poly-ADP-ribose-polymerase (PARP) activity and posttranslational poly-ADP-ribosylation of several regulatory proteins involved in inflammation and energy metabolism. These experiments test the hypothesis that PARP inhibition will modulate hind limb ischemia reperfusion (IR) in a mouse model of type-II diabetes and(More)
A case of absence of the right common carotid artery with origin of the external carotid artery from the innominate artery and origin of the internal carotid artery from the right subclavian artery proximal to the right vertebral artery is presented. Atherosclerotic occlusion at the origin of the right subclavian artery and occlusion of the left internal(More)
Symptomatic peripheral septic embolism is a rare systemic complication of infective endocarditis. This case report describes abdominal pain secondary to a septic pseudoaneurysm in the distal superior mesenteric artery. Presentation, imaging, surgical intervention, and histologic evaluation are described, and a review of recent literature relating to this(More)
INTRODUCTION Injury to the subclavian and axillary arteries is uncommon. Exposure of these vessels is associated with significant morbidity, and mortality ranges from 5% to 30%. Endovascular methods may offer an alternative approach to these technically challenging injuries. METHODS We retrospectively studied patients with blunt or penetrating (including(More)
