OBJECTIVE Cell therapy is an exciting area of investigation for repair of injured myocardial tissue. Platelet-rich plasma (PRP) is an autologous fractionation of whole blood containing high concentrations of growth factors including vascular endothelial growth factor and insulin-like growth factor, among many others. PRP has been shown to safely and(More)
A 26-year-old man presented to a local emergency department with hematemesis and melena associated with mild mid-epigastric abdominal discomfort and light-headedness. He had no prior history of gastrointestinal (GI) bleeding, but he recalled having as a young child, up to 10 years of age, intermittent self-limited attacks of crampy abdominal pain that were(More)
OBJECTIVES Respiratory syncytial virus (RSV) is an important cause of upper respiratory infections and is known to play a causal role in the pathogenesis of rhinitis, sinusitis, acute otitis media, and pneumonia. RSV appears to prime the respiratory tract to secondary inciting events, such as bacterial or antigen challenges. To study the proinflammatory(More)
The main cause of mortality after the first year from cardiac transplantation is cardiac allograft vasculopathy (CAV), which leads to chronic rejection of the heart. To improve long-term outcomes in cardiac transplantation, treatments to prevent or diminish CAV are actively being researched. Ischemia-reperfusion (I-R) injury has been shown to be the(More)
BACKGROUND In this study we systematically dissect the prenylation pathway to better define the mechanism behind statin inhibition in chronic allograft rejection in heart transplants, or transplant coronary artery disease (TCAD). METHODS Utilizing a murine heterotopic heart transplant model, animals received daily treatments of either statin or selective(More)
t can hardly be argued that cardiac imaging methodologies argeting small-animal models have been crucial for rapidly ransitioning therapies from bench to bedside. The adaptation f ultrasound for imaging murine hearts, for example, has llowed characterization of the developing and adult rodent eart, making it an essential tool for the study of developmenal(More)
A 53-year-old woman presented with severe, post-prandial generalized abdominal pain and a 50-pound unintentional weight loss over a 3-month period. There had been a prior chronic history of this discomfort, but it had never reached this level of severity and it had not been associated with weight loss. Over the previous 3 months, her symptoms worsened to(More)
OBJECTIVE The purpose of this study was to examine the practice patterns of intraoperative completion imaging (CI) for lower extremity bypass (LEB) in the Vascular Quality Initiative (VQI). METHODS A retrospective review of all LEB procedures in the VQI database from January 2003 to October 2013 was performed. Regions with fewer than 200 LEB procedures(More)
Stroke is an exceedingly rare presentation of arterial thoracic outlet syndrome (aTOS). This report describes a case of cerebellar stroke secondary to aTOS and reviews the literature. A 56-year-old woman with no previous history of stroke or arm ischemia presented with vertigo. Computed tomography (CT) and magnetic resonance imaging confirmed a left(More)
