Unexplained cardiac arrest (UCA) with documented ventricular fibrillation (VF) is a major cause of sudden cardiac death. Abnormal sympathetic innervations have been shown to be a trigger of ventricular fibrillation. Further, adequate expression of SEMA3A was reported to be critical for normal patterning of cardiac sympathetic innervation. We investigated(More)
AIMS Managed ventricular pacing (MVP) and Search AV+ are representative dual-chamber pacing algorithms for minimizing ventricular pacing (VP). This randomized, crossover study aimed to examine the difference in ability to reduce percentage of VP (%VP) between these two algorithms. METHODS AND RESULTS Symptomatic bradyarrhythmia patients implanted with a(More)
We developed a method of space analysis based on the fact that the measurement between the distal surfaces of the mandibular permanent lateral incisors was approximately equal to that of the combined widths of the mandibular permanent canine and premolars. This method is referred to as Interlateral Incisor Width (I.L.I.W.) Analysis. One hundred and nineteen(More)
BACKGROUND House dust mite (HDM) is the major indoor allergen for allergic diseases such as allergic rhinitis (AR) and asthma. Although sublingual immunotherapy is a curative treatment for HDM-induced AR, data from large-scale studies are limited. We evaluated the efficacy and safety of HDM tablets in adolescent and adult patients (aged 12-64 years) with(More)
BACKGROUND To clarify the influence of hypertension and blood pressure (BP) control on thromboembolism and major hemorrhage in patients with nonvalvular atrial fibrillation, a post hoc analysis of the J-RHYTHM Registry was performed. METHODS AND RESULTS A consecutive series of outpatients with atrial fibrillation was enrolled from 158 institutions. Of(More)
In order to investigate why crystal symmetry lowers with increasing temperature by phase transition of T II–III (=369 K) in Cs 3 H(SeO 4) 2 , in spite of the fact that crystal symmetry in the high-temperature phase of many ionic conductors becomes higher by the phase transition, we have studied the relation between the change in crystal symmetry and the(More)
We propose a novel active islanding prevention method for large penetration of photovoltaic (PV) systems by detecting the harmonic impedance change, and have developed the simulation models for PV inverters which have new active methods by using PSCAD/EMTDC. We also study the performance of islanding detection functions in non detection zone (NDZ) by(More)
