BACKGROUND Previous pathological and clinical studies demonstrated an intimal defect in patients with acute aortic intramural hematoma (IMH). The purpose of this study was to investigate the prevalence and clinical outcome of intimal defect detected by multidetector computed tomography (MDCT) in patients with IMH. METHODS AND RESULTS We retrospectively(More)
We present Si nanotubes prepared by reductive decomposition of a silicon precursor in an alumina template and etching. These nanotubes show impressive results, which shows very high reversible charge capacity of 3247 mA h/g with Coulombic efficiency of 89%, and also demonstrate superior capacity retention even at 5C rate (=15 A/g). Furthermore, the capacity(More)
This study demonstrates that the production of reactive oxidizing species (e.g., hydroxyl radical (•OH)) during the photolysis of nitrite (NO2(-)) or nitrate (NO3(-)) leads to the oxidative conversion of arsenite (As(III)) to arsenate (As(V)). While the direct UV photolytic oxidation of As(III) was absent, nitrite (20 or 200 μM) addition markedly(More)
BACKGROUND  Limited data are available for sex-based differences in Japanese patients with acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PCI). METHODS AND RESULTS  The study patients comprised 1,197 women and 3,182 men who underwent primary PCI for AMI in 2005-2007. Compared with the men, the women were(More)
Emerging mobile systems integrate a lot of functionality into a small form factor with a small energy source in the form of rechargeable battery. This situation necessitates accurate estimation of the remaining energy in the battery such that user applications can be judicious on how they consume this scarce and precious resource. This paper thus focuses on(More)
BACKGROUND Limited data are available for gender-based differences in patients undergoing coronary revascularization. This study aimed to identify gender-based differences in risk factor profiles and outcomes among Japanese patients undergoing coronary revascularization. METHODS AND RESULTS The subjects consisted of 2,845 women and 6,843 men who underwent(More)
The availability of iron has been thought to be a main limiting factor for the productivity of phytoplankton and related with the uptake of atmospheric CO(2) and algal blooms in fresh and sea waters. In this work, the formation of bioavailable iron (Fe(II)(aq)) from the dissolution of iron oxide particles was investigated in the ice phase under both UV and(More)
Batch cryptography has been developed into two main branches batch verification and batch identification. Batch verification is a method to determine whether a set of signatures contains invalid signatures, and batch identification is a method to find bad signatures if a set of signatures contains invalid signatures. Recently, some significant developments(More)
OBJECTIVE The management of asymptomatic severe and very severe aortic stenosis (AS) remains unestablished. This study aimed to investigate the clinical outcomes of severe versus very severe AS patients. DESIGN A single centre, retrospective cohort study. PATIENTS AND METHODS The study retrospectively reviewed 108 conservatively treated patients with(More)
OBJECTIVES Surgical papillary muscle (PM) imbrication has been reported to be effective to relieve leaflet tethering in patients with functional mitral regurgitation (FMR). However, the mechanism that contributes to improvement of FMR by shortening the interpapillary muscle distance (IPMD) has not been well investigated. The purpose of the present study was(More)
