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 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)
PURPOSE To find out an effective prognostic factor for early stage non-small cell lung cancer (NSCLC), we examined the relationship of the degree of tenascin-C (TN-C) degradation in relapsed NSCLC tumors with the prognosis of the patients. The molecular mechanism of TN-C degradation was also evaluated. EXPERIMENTAL DESIGN In 63 stage-1 NSCLC patients,(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)
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)
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)
A male patient was suspected as olivo-ponto-cerebellar atrophy from the clinical and computed tomographic features at 34 years of age. Afterwards, his dysarthria and limb ataxia were slowly and steadily worsened. He was finally bed-ridden and unresponsive, and died of hyperpyrexia and general wasting at 37 years of age. It was noted that laboratory(More)
To elucidate differential roles of protein kinase C isozymes in pancreatic islet cells, the precise localization of the isozymes in rabbit and rat islet endocrine cells was investigated using monoclonal antibodies specific for three types of the enzyme. We detected strong immunoreactivity for the type III protein kinase C in B cells. Immunoreactivity for(More)
