BACKGROUND Transluminal stent-graft placements (TSGPs) are a new, less invasive procedure now recognized as the choice for aortic disease repair. Treatment of aortic dissections with TSGPs has resulted in good early results, but the long-term results and changes in the false lumen have not been elucidated in detail. METHODS AND RESULTS TSGPs were(More)
OBJECTIVE Tenascin-C, an extracellular matrix glycoprotein, is thought to play an important role in neointimal hyperplasia of artery bypass grafts. In this study, the direct contribution of tenascin-C to neointimal hyperplasia of free artery grafts and the origin of tenascin-C-producing cells were examined using tenascin-C transgenic mice. METHODS AND(More)
The aim of this study was to investigate how insulin secretion is controlled by phosphorylation of the myosin light chain (MLC). Ca2+-evoked insulin release from pancreatic islets permeabilized with streptolysin O was inhibited by different monoclonal antibodies against myosin light-chain kinase (MLCK) to an extent parallel to their inhibition of purified(More)
OBJECTIVE Neointimal hyperplasia at the arterial anastomotic site is a critical problem during cardiovascular surgery. It has been suggested that tenascin-C (TN-C), an extracellular matrix (ECM) glycoprotein, might play an important role in neointimal hyperplasia. In this study, the direct contribution of tenascin-C to neointimal hyperplasia after aortotomy(More)
The effects of cilostazol (OPC-13013, 6-[4-(1-cyclohexyl-1H-tetrazol-5-yl)butoxy]-3,4-dihydro-2(1H)-quin olinone) on cyclic nucleotide metabolism and Ca2+-induced contraction of intact and skinned rabbit arterial smooth muscles were investigated. The concentrations of cilostazol producing 50% inhibition of cyclic adenosine monophosphate phosphodiesterase(More)
BACKGROUND Transluminal stent-graft placement (TSGP) for aortic dissection is a relatively new procedure. We performed TSGPs to seal the primary entry site to treat and prevent complications of aortic dissection. The early to mid-term outcomes were analyzed. METHODS AND RESULTS Thirty-seven patients with a primary intimal tear in descending aorta(More)
Monoclonal antibodies raised against rabbit brain protein kinase C were classified into at least three types, MC-1a, MC-2a, and MC-3a, which selectively interact with hydroxyapatite column chromatographically resolved isozymes type I, II, and III of protein kinase C, respectively, determined on the basis of immunoblotting experiments. Immunoprecipitating(More)
OBJECTIVES p38 mitogen-activated protein kinase is associated with many clinical entities characterized by inflammation. We postulated that inhibition of p38 mitogen-activated protein kinase with FR167653 attenuates inflammation and the development of pulmonary hypertension in monocrotaline-treated rats. METHODS Rats were divided into 4 groups: (1) the(More)
The pathogenesis of obliterative bronchiolitis (OB) following lung and heart-lung transplantation remains unclear. We evaluated the role of CsA and IL-2 on the development of obliterative airway disease (OAD) by administrating exogenous IL-2 in a CsA-treated rat tracheal transplant model. Tracheal grafts were implanted into the peritoneal cavity from Brown(More)
