BACKGROUND Although several trials have demonstrated the safety of drug-eluting stent (DES) implantation for acute myocardial infarction (AMI) patients, care must be exercised when DES are implanted in AMI cases because of the risk of in-stent thrombosis or adverse side effects of antiplatelet agents. On the other hand, recently, there has been much(More)
Substrate binding triggers catalytic radical formation through the cobalt-carbon bond homolysis in coenzyme B12-dependent enzymes. We have determined the crystal structure of the substrate-free form of Klebsiella oxytoca diol dehydratase*cyanocobalamin complex at 1.85 A resolution. The structure contains two units of the heterotrimer consisting of alpha,(More)
OBJECTIVES To investigate the optimal method of coronary revascularization in patients on dialysis. METHODS We retrospectively analyzed 145 patients on dialysis who underwent percutaneous coronary intervention (PCI) (81 patients) or coronary artery bypass grafting (CABG) (64 patients). Survival and non-fatal cardiac event-free rates were compared between(More)
A new nanophase-separated structure with parallel double periodicity has been identified for an undecablock terpolymer in bulk. The polymer includes two long poly(2-vinypyridine) (P) chains on each end, with five short polyisoprene (I) and four short polystyrene (S) chains at the center. This polymer exhibits a hierarchical lamellar structure with two(More)
Carcinosarcomas, often referred to as malignant mixed tumors, are rare neoplasm. We reported herein a carcinosarcoma of the gallbladder in an elderly patient with long-term survival (4 years). The operation carried out was open cholecystectomy under the preoperative diagnosis of chronic cholecystitis and tumor of the gallbladder. Anticancer chemotherapy(More)
BACKGROUND Usefulness and efficacy of intravascular ultrasound (IVUS) for the implantation of sirolimus-eluting stent (SES) is controversial. We investigated the primary and mid-term results of SES deployment with angiographic guidance comparing with IVUS guidance, retrospectively. METHODS AND RESULTS SESs were deployed in 480 de novo lesions of 459(More)
BACKGROUND Although drug-eluting stents (DES) are widely used today, bare metal stents (BMS) are still frequently employed. We investigated the utilization and clinical outcomes of BMS implantation since we first began using DES. METHODS The clinical course following percutaneous intervention with de novo implantation of BMS was studied beginning in July(More)
A 29-year-old man was admitted with right hypochondralgia and fever. Markedly dilated bile ducts were observed, mainly in the right lobe of the liver. Based on both the clinical findings and imaging, we diagnosed Caroli's disease and choledochal cyst complicated with cholangitis. Hepatocellular carcinoma (HCC) was also observed in segment 3, and the tumor(More)
The safety of docetaxel (60 mg/m(2)) plus cyclophosphamide (600 mg/m(2)) every three weeks (TC) as adjuvant therapy for Japanese women with operable breast cancer was evaluated. Ehime TC Study Group initiated the randomized control study,which compared the effects of the TC course number (4 cycles versus 8 cycles) in the adjuvant setting on the treatment(More)
