Recent studies implicate channels of the transient receptor potential vanilloid family (e.g., TRPV1) in regulating vascular tone; however, little is known about these channels in the coronary circulation. Furthermore, it is unclear whether metabolic syndrome alters the function and/or expression of TRPV1. We tested the hypothesis that TRPV1 mediates(More)
Six monoclonal anti-Ly-2.1 antibodies are described that arose from a single fusion using the spleen from a 129/ReJ mouse immunized with CBA/H thymus cells. The specificity was determined from the strain distribution, and testing of congenic strains where all six monoclonal antibodies detected the Ly-2.1 alloantigen. Furthermore, the antibodies fall into(More)
BACKGROUND Stent-induced neointimal hyperplasia is a major cause of morbidity following stent deployment in patients with coronary artery disease. Importantly, however, mechanisms underlying stent-induced neointimal hyperplasia are unclear. This pathological response to stent placement is more aggressive when stents are over-expanded, suggesting that(More)
Peripheral-blood mononuclear cells from renal-allograft patients receiving cyclosporin A (CSA) were tested for their ability to produce T cells cytotoxic for EB-virus-infected B-cell targets in culture and compared with those from healthy seropositive subjects. Whereas in the control cultures the proliferating foci of EB-virus-transformed B cells regressed(More)
Peripheral blood lymphocytes from normal seropositive donors and renal transplant recipients on various immunosuppressive regimens have been tested for their ability to mount a cytotoxic response when cultured with autologous EB virus-infected B cells and thereby to cause regression of proliferating b-cell foci. Cultures from 10 normal seropositive donors(More)
Fetuin-A is a known inhibitor of vascular calcification in vitro. In arteries with calcification, there is increased immunostaining for fetuin-A. However, vascular smooth muscle cells (VSMC) do not synthesize fetuin-A, suggesting fetuin-A may be endocytosed to exert its inhibitory effects. To examine the mechanism by which fetuin-A is taken up in bovine(More)
Metabolic syndrome (MetS), a compilation of associated risk factors, increases the risk of type 2 diabetes and coronary artery disease (CAD, atherosclerosis), which can progress to the point of artery occlusion. Stents are the primary interventional treatment for occlusive CAD, and patients with MetS and hyperinsulinemia have increased restenosis. Because(More)
AIMS Stenting attenuates restenosis, but accelerated coronary artery disease (CAD) adjacent to the stent (peri-stent CAD) remains a concern in metabolic syndrome (MetS). Smooth muscle cell proliferation, a major mechanism of CAD, is mediated partly by myoplasmic Ca2+ dysregulation and store-operated Ca2+ entry (SOCE) via canonical transient receptor(More)
OBJECTIVE Assessment of ventricular function in the fetus has been limited for many reasons, including relative cardiac size and atypical orientation of fetal cardiac structures. A myocardial performance index (MPI) has been described in adult and pediatric populations as an echocardiographic measure of global (systolic and diastolic) ventricular(More)
