Recent studies have shown that histones, the chief protein component of chromatin, are released into extracellular space during sepsis, trauma, and ischemia-reperfusion injury, act as major mediators death an organism. This study was designed to elucidate cellular molecular basis histone-induced lethality assess protective effects recombinant thrombomodulin (rTM). rTM has been approved for treatment disseminated intravascular coagulation (DIC) in Japan, is currently undergoing a phase III...
The effects of the anti-methanogenic compound, bromochloromethane (BCM), on rumen microbial fermentation and ecology were examined in vivo . Japanese goats fed a diet 50 % Timothy grass concentrate then sequentially adapted to low, mid high doses BCM. placed into respiration chambers for analysis function methane H 2 production. levels production reduced by 5, 71 91 %, was estimated at 545, 2941 3496 mmol/head per d, response BCM, respectively, with no effect maintenance feed intake...

Background: Pulsed-field ablation (PFA) is a nonthermal energy with higher selectivity to myocardial tissue in comparison radiofrequency (RFA). We compared the effects of PFA and RFA on heterogeneous ventricular scar swine model healed infarction. Methods: In 9 swine, infarction was created by balloon occlusion left anterior descending artery. After survival period 8 10 weeks, or performed at infarct border zones identified abnormal electrograms. group (4 swine), lattice catheter (Sphere-9,...
Inappropriate cardiac remodeling and repair after myocardial infarction (MI) predisposes to heart failure. Studies have reported on the potential for lineage negative, steel factor positive ( c - kit + ) bone marrow-derived hematopoetic stem∕progenitor cells (HSPCs) damaged myocardium through neovascularization myogenesis. However, precise contribution of c-kit signaling pathway process has yet be determined. In this study, we sought directly elucidate mechanistic contributions in...
Background: The prevalence, gender- and age-related differences, ablation success rate inter-relationship between the origins of idiopathic ventricular arrhythmias (I-VA) have not been clarified. Methods Results: A total 625 consecutive patients with symptomatic, drug resistant I-VA (315 males 310 females; mean age, 54±17 years; 218 tachycardias, 407 premature contractions) who underwent catheter were studied. divided into 5 groups based on VA origin: (1) outflow tract (OT)-VA, consisting...
The association between serum uric acid (UA) levels and left ventricular hypertrophy (LVH) remains unclear. We aimed to investigate this using electrocardiographic findings. Health examination data from Kagoshima Kouseiren Hospital included 79,200 participants without cardiovascular diseases. Hypertension was defined as a blood pressure ≥ 140/90 mmHg. A Sokolow–Lyon criterion of 3.5 mm used define LVH. Sex-specific associations UA LVH were adjusted for age, body mass index, systolic...
The Japanese Hypertrophic Cardiomyopathy Registry Study was designed to provide comprehensive, real-world insights into the clinical characteristics and management of hypertrophic cardiomyopathy (HCM) in Japan. This multicentre, prospective study enrolled consecutive patients with HCM from 24 referral hospitals across Japan starting 2016. baseline 1485 by December 2019 are presented this analysis. median ages at registration diagnosis were 69 60 years, respectively, men accounting for 54%...
Perforation of a coronary venous branch for pericardial insufflation carbon dioxide (CO2) enhances safety epicardial access. The multiple procedural steps and length the procedure remain major limitation this approach impacting its routine clinical adoption. This study describes novel streamlined technique CO2 via radiofrequency (RF)-assisted right atrial appendage (RAA) perforation. Between 2023 2024, 18 patients (age: 55 ± 11 years; left ventricular ejection fraction: 44 13%) underwent...
ABSTRACT Background The use of an automated annotation algorithm based on the maximal negative derivative unipolar potential (−dV/dTmax) for local activation timing in ablation outflow tract (OT) ventricular premature contractions (VPCs) remains controversial. Objective To investigate spatial differences earliest sites (EASs) OT‐VPCs identified by −dV/dTmax versus manual using bipolar potentials. Methods Seventy‐nine patients with frequent who underwent successful were included. VPCs...
We present results of a search for proton decays, p→¯νK+, using data from 33kt˙yr exposure the Super-Kamiokande detector. Two decay modes kaon, K+→μ+νμ and K+→π+π0, were studied. The consistent with background expected atmospheric neutrinos; therefore lower limit on partial lifetime τ/B(p→¯νK+) was found to be 6.7×1032years at 90% confidence level.Received 22 February 1999DOI:https://doi.org/10.1103/PhysRevLett.83.1529©1999 American Physical Society
Structural remodeling in chronic atrial fibrillation (AF) occurs over weeks to months. To study the electrophysiological, structural, and functional changes that occur AF, selection of best animal model is critical. AF was induced by rapid pacing (50-Hz stimulation every other second) pigs (n = 4), dogs 8), goats 9). Animals underwent MRIs at baseline 6 mo evaluate left ventricular (LV) ejection fraction (EF). Dogs were given metoprolol (50-100 mg po bid) digoxin (0.0625-0.125 limit response...
The east-west anisotropy, caused by the deflection of primary cosmic rays in Earth's magnetic field, is observed for first time flux atmospheric neutrinos. Using a 45 kt yr exposure Super-Kamiokande detector, 552 $e$-like and 633 $\ensuremath{\mu}$-like horizontally going events are selected momentum range between 400 $3000\mathrm{MeV}/c$. azimuthal distributions agree with expectation from neutrino calculations, verifying that neutrinos GeV energy reasonably well modeled calculations...
