BACKGROUND Percutaneous intervention for symptomatic renal artery fibromuscular dysplasia (FMD) has replaced surgical therapy as first-line treatment. This study evaluates the factors that impact long-term anatomic and functional outcomes of endovascular therapy for symptomatic renal artery FMD. METHODS Records of patients who underwent renal artery(More)
BACKGROUND Endoluminal therapy for superficial femoral artery (SFA) occlusive disease is commonplace, but the incidence and outcomes of in situ thrombosis (IST) and distal embolization (DE) have not been well defined. The aim of this study was to examine the impact of IST and DE on long-term outcomes of SFA interventions. METHODS A database of patients(More)
The heme-containing enzyme myeloperoxidase (MPO) is both present and active in inflammatory conditions. This enzyme is potentiated by its formation of multiple inflammatory mediators. The two most common mediators are the modified tyrosines: nitrotyrosine and 3-chlorotyrosine. Along with other modified tyrosines, these molecules have been found to be(More)
We have investigated the effects of an improved liposomal formulation (extruded DOTAP:cholesterol (DOTAP:Chol)-DNA complex) on transgene expression in tumor cells and normal cells of murine and human origin both in vitro and in vivo. In vitro, transgene expression was significantly increased (P = 0.01) in human tumor cells compared to normal human cells.(More)
Studies in animals and human clinical trials demonstrate the safety and persistence of recombinant adeno-associated viral (rAAV) serotype 2 vectors in a variety of tissues. rAAV vectors of other serotypes are also being developed for efficient gene transfer. To date, the literature describing these vectors has relied on physical or transducing titers to(More)
Percutaneous renal artery revascularization for hypertension and renal dysfunction is now common, and there is an increasing realization that renal artery intervention can be associated with parenchymal injury. The frequency, cause, and outcomes of acute functional injury associated with renal intervention are poorly delineated. Our aim was to determine the(More)
Abnormal phosphatase and tensin analog (PTEN) gene expression has been noted in neoplasms. The PTEN protein cleaves phosphate groups from cellular growth kinases inhibiting tumor propagation. A downstream target ofPTEN is AKT, a serine-threonine kinase that when activated inhibits apoptosis. We sought to determine whether PTEN overexpression in(More)
BACKGROUND While aggressive endoluminal therapy for superficial femoral artery (SFA) occlusive disease is commonplace, the implications of runoff on long-term outcomes of these interventions in patients with rest pain and tissue loss is unclear. Runoff is known to negatively effect graft patency. The aim of this study is to examine the impact of distal(More)
The ratio of pro-apoptotic (PAP) and anti-apoptotic (AAP) bcl-2 proteins is important in apoptosis regulation. We sought to determine if inhibition of the AAP bcl-xl by sodium butyrate (SB) would augment apoptotic cellular death in mesothelioma when combined with adenoviral pro-apoptotic gene therapy (PAGT) by simultaneously increasing PAP and decreasing(More)
PURPOSE Carotid artery stenting (CAS) has emerged as an acceptable treatment alternative in high-risk patients with carotid stenosis. The purpose of this study was to assess the effect of the learning curve on treatment complications and the clinical outcomes of CAS. METHODS Clinical variables and treatment outcomes of 200 consecutive CAS procedures in(More)
