OBJECTIVES The aim of this study was to compare the diagnostic performance of multidetector computed tomography (MDCT) with prospective electrocardiogram (ECG) triggering versus retrospective ECG triggering. BACKGROUND MDCT allows the noninvasive visualization of the coronary arteries. However, radiation exposure is a reason for concern. METHODS One(More)
A longstanding goal for the treatment of hemophilia B is the development of a gene transfer strategy that can maintain sustained production of clotting factor IX (F.IX) in the absence of an immune response. To this end, we have sought to use lentiviral vectors (LVs) as a means for systemic gene transfer. Unfortunately, initial evaluation of LVs expressing(More)
Liver gene transfer is a highly sought goal for the treatment of inherited and infectious diseases. Lentiviral vectors (LVs) have many desirable properties for hepatocyte-directed gene delivery, including the ability to integrate into nondividing cells. Unfortunately, upon systemic administration, LV transduces hepatocytes relatively inefficiently compared(More)
Experimental autoimmune myasthenia gravis (EAMG), a model for human myasthenia (MG), is routinely induced in susceptible rat strains by a single immunization with Torpedo acetylcholine receptor (TAChR). TAChR immunization induces anti-AChR Abs that cross-react with self AChR, activate the complement cascade, and promote degradation of the postsynaptic(More)
Unfavorable complex anatomy or congenital anomalies of supra-aortic vessel take-off may increase carotid artery stenting (CAS) procedural difficulties and complications through the femoral route. We assessed the feasibility, safety, and efficacy of CAS through the right brachial approach in patients in whom left internal carotid artery stenosis and bovine(More)
We previously showed that incorporating target sequences for the hematopoietic-specific microRNA miR-142 into an antigen-encoding transgene prevents antigen expression in antigen-presenting cells (APCs). To determine whether this approach induces immunologic tolerance, we treated mice with a miR-142-regulated lentiviral vector encoding green fluorescent(More)
Stable gene replacement by in vivo administration of lentiviral vectors (LVs) has therapeutic potential for metabolic disorders and other systemic diseases. We studied the expression of intracellular and secreted proteins by LVs in immunocompetent mice. Liver, spleen, and bone marrow cells were efficiently transduced. However, transgene expression, driven(More)
OBJECTIVES The aim of this study was to assess the long-term prognostic role of multidetector computed tomography coronary angiography (CTA) in patients with suspected coronary artery disease (CAD). BACKGROUND Use of CTA is increasing in patients with suspected CAD. Although there is a large body of data supporting the prognostic role of CTA for major(More)
BACKGROUND The aim of this study was to assess the accuracy of a comprehensive multidetector computed tomography (MDCT) evaluation of the aortic annulus (AoA), coronary artery disease (CAD), and peripheral vessels in patients referred for transcatheter aortic valve implantation (TAVI). METHODS In 60 patients referred for TAVI, the following parameters(More)
Noninvasive assessment of coronary in-stent restenosis (ISR) is clinically useful but 4- and 16-slice multidetector computed tomography is limited due to stent strut artifacts. We evaluated the feasibility and accuracy of 64-slice multidetector computed tomography in the diagnosis of ISR to validate its accuracy in ISR quantification and identify factors(More)
