1 Current status of non‐pharmacotherapies in Japan Pacemaker treatment for bradyarrhythmia was first approved national health insurance coverage Japan 1974, and its use rapidly became widespread thereafter. Approximately 40 years later, 2017, the number patients treated with this technology has increased to 60 137 (41 895 new cases approximately 18 242 replacements). 5 Capsule‐shaped leadless pacemaker also available 2016, is being established as a option. Non‐pharmacological...
The original guideline for non-pharmacological treatments (cardiac implantable electronic device, catheter ablation, and arrhythmia surgery) of arrhythmias (Japanese Circulation Society [JCS] Guideline on Non-pharmacotherapy Cardiac Arrhythmias) was first published in 2001, there have been two revisions thereafter (2006 2011). “JCS Indications Procedures Catheter Ablation” 2012 to cover the rapid development expansion ablation techniques. Advances treatment further accelerated since then,...
To determine the role of vascular cell adhesion molecule 1 (VCAM-1)/very late activation antigen 4 (VLA-4) and intercellular (ICAM-1)/lymphocyte function-associated (LFA-1) interactions in causing antigen-induced eosinophil T recruitment into tissue, we studied effect vivo blocking VCAM-1, ICAM-1, VLA-4, LFA-1 by pretreatment with monoclonal antibodies (mAb) to these four molecules on infiltration trachea induced inhalation mice. The VCAM-1 but not ICAM-1 LFA-1, prevented mouse trachea. On...
Models of the active site in [NiFe]hydrogenase enzymes have proven challenging to prepare. We isolated a paramagnetic dinuclear nickel-ruthenium complex with bridging hydrido ligand from heterolytic cleavage H 2 by NiRu aqua water under ambient conditions (20°C and 1 atmosphere pressure). The structure hexacoordinate Ni(μ-H)Ru was unequivocally determined neutron diffraction analysis, it comes closest an effective analog for core proposed form enzyme.
The Impella microaxial-flow pump can directly unload left ventricle (LV) in cases of acute heart failure. Extracorporeal membrane oxygenation (ECMO) is widely used for circulatory support. Although the clinical effectiveness ECMO has been demonstrated, insufficient LV loading reduction may not be advantageous myocardial recovery. objective was to compare ventricular and reversibility fibrillation (VF) with either or ECMO. Six dogs were used. established by femoral artery right atrium. LD...
Objective. Early detection of nerve dysfunction is important to provide appropriate care for patients with diabetic polyneuropathy. The aim this study was assess the echo intensity peripheral and evaluate relationship between conduction results sonographic findings in type 2 diabetes mellitus. Methods. Thirty (mean ± SD, 59.8 10.2 years) 32 healthy volunteers (mean, 53.7 13.9 were enrolled study. cross-sectional area (CSA) evaluated at carpal tunnel proximal wrist (wrist) median tibial...
Objective. Diabetes mellitus is becoming a major cause of premature disability in Japan, and peripheral neuropathy common complication diabetes. The aim this study was to evaluate the relationship between results nerve conduction studies (NCS) size determined by sonography diabetic patients. Methods. Twenty patients (mean age ± SD, 57.1 13.6 years) 20 healthy volunteers (mean, 61.1 8.9 were enrolled study. Patients' wrists that had symptoms carpal tunnel syndrome not included study; those...
We show experimental evidence of the equilibrium surface magnetization α-Cr2O3(0001) by studying chromium at Co(111)/α-Cr2O3(0001) interface. The soft X-ray magnetic circular dichroism intensity from uncompensated Cr spins was found to be almost independent interface roughness and exchange anisotropy energy. Moreover, no bias training effect found, except in transition temperature regime, suggesting that antiferromagnetic spin structure, including arrangement, is equilibrium. Furthermore,...
Abstract A silicon (Si) wafer was heated using concurrent laser irradiation and a heating current under static electric magnetic fields. Si melted locally near the point, flowed, accumulated on surface along direction dictated by Lorentz force. Electric stress exceeding tension pulled melt upward, forming protrusion with an apex surrounded facets. The of grown at -10 kV exhibited {001}, {113}, {111} facets, whereas -13 featured small protrusions faceted surfaces. In contrast, formed solely...

Abstract We apply the interpenetration network (IPN) gel of poly( N ‐isopropylacrylamide) (PNIPAm) and poly(sodium acrylate) (PNaAAc) to stimuli‐responsive heavy‐metal‐ion adsorbent system. In IPN system, PNIPAm PNaAAc units are expected behave independently. Therefore, exhibits a thermosensitive volume–phase transition behavior in spite presence polyelectrolytes like that well known prevent from shrinking when above their lower critical solution temperature (LCST). NIPAm‐co‐NaAAc copolymer...
Abstract In the presence of a catalyst generated from GaCl3 and silver salt (AgClO4 or AgSbF6), Friedel-Crafts acylation reaction aromatic compounds such as anisole veratrole with acid anhydrides smoothly proceeds to afford corresponding ketones in high yields.
Dislocation density in GaAs layers grown on Si substrates has been investigated by measuring in-depth profile of the etch pit (EPD) using a molten KOH. Reduction EPD into 10 7 cm -2 level for layer 2-3 µm thickness is attained post annealing at 900°C 30 min. Further reduction dislocation achieved In x Ga 1- As-GaAs y P strained-layer superlattices (SLS's); step-like SLS's and its continuous decrease even passing through have observed.
Coarse grained dynamically reconfigurable processor arrays (DRPAs) have been received an attention as a flexible and efficient off-loading engine in System-On-Chips (SoCs). Evaluation results recent researches revealed that the parameters of optimal array structure: granularity, functions, size, context size interconnection flexibility, are completely different for each application. That is, DRPAs should be configurable target SoCs applications. MuCCRA is project developing DRPA generator...
It is well known that the columnar dendrite grows in a direction opposing liquid flow. Therefore, order to make clear fluid flow within pool, solidification structures of steel slabs cast continuously by curved mould bending type machine were investigated. At same time, amount large inclusions trapped upper part slab was measured method X-ray radiography. The following results obtained;(1) deflection angle dendrite, depending on rate and velocity along solidified shell, at edge slab, but...
Tensile, fracture toughness, and high cycle fatigue tests were done at 293, 77, 4 K for Ti-6Al-4V alloys with three levels of oxygen content. The investigated both in as-forged condition the rolled condition. Rolling did not necessarily make α grains finer, but changed shape from plate-like to globular. Strengths depended mainly on content; lower content produced strengths. alloy lowest showed best ductility K. toughness cryogenic temperature was also enhanced by reduction oxygen. In alloy,...
Abstract O-Trimethylsilyl monothioacetals, which are generally difficult to activate under acidic conditions due their rapid disproportionation, smoothly react with triethylsilane in the presence of a novel catalyst system, trimethylsilyl chloride and indium(III) chloride, afford corresponding sulfides good high yields. One pot synthesis from aldehydes is also attained yields by successive treatments alkyl (aryl) above system extremely mild conditions.
This paper describes the dependence of dislocation density reduction effect on employing position either thermal cyclic annealing (TCA) or InGaAs-GaAs strained-layer superlattice (SLS) in GaAs-on-Si grown by metalorganic chemical vapor deposition (MOCVD). The is reduced to one twenty-fifth that as-grown sample TCA as becomes farther than about 1.5 µm from Si surface. additionally third SLS 2.0 µm. As a result, × 10 6 cm -2 combined use and SLS. determined mainly degree residual stress. That...
