The use of the metastable equilibrium solubility (MES) concept to describe the solubility properties of carbonated apatites (CAPs) and human dental enamel (HE) has been well established in previous studies using a range of CAPs with varying carbonate contents and crystallinities. It was shown in these studies that the mean value of the CAP MES is directly(More)
BACKGROUND The efficacy of sirolimus-eluting stents (SESs) has not been established in dialysis patients. METHODS AND RESULTS This study was a non-randomized observational single-center registry in a community hospital: data for 80 consecutive dialysis patients who underwent percutaneous coronary intervention (PCI) with SES were compared with those of a(More)
Elevated fibrinogen levels after coronary balloon angioplasty have been reported to be useful in predicting restenosis. Therefore, we sought to evaluate the relationship between preprocedural fibrinogen levels and the 6-12-month outcomes of patients undergoing coronary stenting. Plasma levels of fibrinogen were measured in 390 consecutive patients prior to(More)
BACKGROUND Diverse pharmacological effects of anti-platelet thienopyridines due to individual differences in metabolism have been reported. However, an association between on-treatment platelet reactivity and adverse ischemic events after drug-eluting stent (DES) implantation in Japanese patients has not been fully elucidated. METHODS AND RESULTS A total(More)
BACKGROUND The current development of serological biomarkers allows detection of smaller myocardial necrosis and early acute myocardial infarction (AMI). We evaluated the relevance of the heart-type fatty acid binding protein (H-FABP) assay, which has recently been approved in Japan, for early diagnosis of AMI as compared with the sensitive troponin assay.(More)
OBJECTIVE Very late stent thrombosis (VLST) remains an unresolved problem, and recent reports have indicated that VLST onset can occur in patients treated with both drug-eluting stents (DES) and bare metal stents (BMS). We evaluated the causes of VLST using optical coherence tomography (OCT). METHODS OCT was performed in 22 patients (12 DES-treated(More)
Previous studies have shown that carbonated apatites with a range of carbonate contents and crystallinities exhibit the phenomenon of metastable equilibrium solubility (MES) distributions. The purpose of the present study was to investigate the solubility behavior of bone mineral using the concepts of MES and MES distributions and, together with(More)
A 3-year-old girl with fever and neck swelling showed widening of the superior mediastinum on chest radiographs. Contrast-enhanced CT of the neck revealed ill-defined low-attenuation areas with a thick, enhanced rim adjacent to the hypertrophied palatine tonsil. The abscess extended inferiorly within the carotid sheath between the carotid artery and the(More)
BACKGROUND The efficacy of drug-eluting stents after rotational atherectomy (ROTA) has not been clarified. METHODS AND RESULTS The 704 consecutive patients who underwent percutaneous coronary intervention (PCI) with a sirolimus-eluting stent (SES) (79 with and 625 without ROTA) were enrolled. The 2-year clinical outcome of these patients was compared with(More)
BACKGROUND It is unknown whether adenosine triphosphate disodium (ATP) administration during primary percutaneous coronary intervention (PCI) is useful in anterior acute myocardial infarction (AMI). METHODS The study was a prospective, non-randomized, open-label trial. Primary PCI was successfully performed in 204 consecutive patients with first anterior(More)
