BACKGROUND The antiplatelet drug cilostazol is efficacious for prevention of stroke recurrence compared with placebo. We designed the second Cilostazol Stroke Prevention Study (CSPS 2) to establish non-inferiority of cilostazol versus aspirin for prevention of stroke, and to compare the efficacy and safety of cilostazol and aspirin in patients with(More)
To elucidate the utility of benzodiazepine receptor imaging for the detection of viable cortical neurons, dual-tracer autoradiography using iodine-125 iomazenil (IMZ) and iodine-123 N-isopropyl-4-iodoamphetamine (IMP) was performed in a model of reversible focal ischaemia during the acute and subacute phases. The right middle cerebral artery of(More)
Early diagnosis of Parkinson's disease (PD) is important for the potential application of neuroprotective therapies. The purpose of this study was to assess the detection of the early changes of PD by either imaging the dopamine transporter (DAT) or uptake of L-3,4-dihydroxyphenylalanine (L-DOPA). An early to advanced stage model of PD was induced in rats(More)
We examined the effect of cardioprotective agents on three distinct phases of the H2O2-induced response that leads to loss of mitochondrial membrane potential (DeltaPsi(m)) and cell death in cultured cardiac myocytes: (1) priming, consisting of calcium-dependent morphological changes in mitochondria (swelling and loss of cristae), with preserved(More)
To elucidate the role of intracellular Na+ kinetics during ischemia and reperfusion in postischemic contractile dysfunction, intracellular Na+ concentration ([Na+]i) was measured in isolated perfused rat hearts using 23Na nuclear magnetic resonance spectroscopy. The extension of the ischemic period from 9 minutes to 15, 21, and 27 minutes (at 37 degrees C)(More)
We tested the hypothesis that accumulation of H+ or inorganic phosphate (Pi) is responsible for the early contractile failure of hypoxia by measuring maximal Ca2+-activated pressure and 31P nuclear magnetic resonance spectra in Langendorff-perfused ferret hearts at 30 degrees C. Maximal Ca2+-activated pressure was identified by the saturation of pressure(More)
BACKGROUND To implement personalized medicine, we established a large-scale patient cohort, BioBank Japan, in 2003. BioBank Japan contains DNA, serum, and clinical information derived from approximately 200,000 patients with 47 diseases. Serum and clinical information were collected annually until 2012. METHODS We analyzed clinical information of(More)
BACKGROUND Quality management in health care services has not been as successful as in other industries. OBJECTIVE To assess the potential contribution of an on-line incident reporting system (OIRS) and of an electronic patient record (EPR) system to quality management in hospitals. METHODS The two approaches are being implemented in Osaka University(More)
BACKGROUND We established a patient-oriented biobank, BioBank Japan, with information on approximately 200,000 patients, suffering from any of 47 common diseases. This follow-up survey focused on 32 diseases, potentially associated with poor vital prognosis, and collected patient survival information, including cause of death. We performed a survival(More)
