The Southwest Pacific Ocean Circulation and Climate Experiment (SPICE) is an international research program under the auspices of CLIVAR.The key objectives are to understand circulation South Convergence Zone (SPCZ) dynamics, as well their influence on regional basin-scale climate patterns.South thermocline waters transported in westward flowing Equatorial Current (SEC) toward Australia Papua-New Guinea.On its way, SEC encounters numerous islands straits forms boundary currents jets that...
Abstract Aims Altered thyroid hormone metabolism characterized by a low triiodothyronine (T3), so‐called low‐T3 syndrome, is common finding in patients with severe systemic diseases. Additionally, subclinical dysfunction, defined as abnormal stimulating (TSH) and normal thyroxine (T4), causes left ventricular dysfunction. Our objective was to identify the prevalence prognostic impact of syndrome dysfunction acute decompensated heart failure (ADHF). Methods results We examined 274 ADHF who...
Although the important role of fibroblast growth factor (FGF)23 on cardiac remodeling has been suggested in advanced chronic kidney disease (CKD), little is known about serum (s)FGF23 levels patients with heart failure (HF) due to nonischemic (NICD) and early CKD. The present study aimed investigate sFGF23 NICD identify responsible factors for elevation levels. We prospectively measured consecutive hospitalized CKD (estimated glomerular filtration rate ≥ 40 ml·min(-1)·1.73 m(-2)) analyzed...
Objective Atrial functional mitral regurgitation (A-FMR) has been suggested as a new aetiology of MR (MR); however, its prognosis and prognostic predictors are not fully elucidated. Aim this study was to investigate the A-FMR in comparison with ventricular (V-FMR). Methods Three hundred seventy-eight consecutive patients moderate-to-severe or severe were studied. Functional classified into V-FMR (N=288) (N=90) depending on alterations left ventricle (LV) atrium (LA) along clinical context...
JAMSTEC have been monitoring changes in underground fluid pressure, or "pore pressure," from boreholes near the site of 1944 Tonankai earthquake southwestern Japan. These are linked to Slow Slip Events (SSEs), which occur on boundary between Eurasian plate and subducting Philippine Sea beneath Nankai Trough. By connecting their borehole observatory (LTBMS) a seafloor network (DONET), they now collect real-time pore pressure data, allowing them update SSE catalog.This updated catalog revealed...
Patients with heart failure (HF) have a high risk of cardiovascular (CV) death and re-hospitalization. The purpose the present study was therefore to investigate predictors CV re-hospitalization for acute decompensated HF (ADHF). A total 225 patients aged 67.2±15.2 years, including 134 men (59.6%), who were hospitalized ADHF between 2008 2009, followed up. After discharge, relationship clinical parameters events (ie, or HF) examined. Follow-up continued until 30 April 2011. most important...
The semi-enclosed Solomon Sea in the southwestern tropical Pacific is on pathway of a major oceanic circuit connecting subtropics to equator via energetic western boundary currents. Waters transiting through this area replenish Warm Pool and ultimately feed equatorial current system, particular undercurrent. In addition dynamical transformations, water masses undergo nutrient micronutrient enrichment when coming contact with coasts, impacting productivity downstream region. Broadscale...
Background Early detection for worsening renal function (WRF) is indispensable in patients with acute decompensated heart failure (HF). We tested the hypothesis that difference circulating levels of each B-type or brain natriuretic peptide (BNP) molecular form associated occurrence WRF. Methods and Results Circulating proBNP, NT-proBNP (N-terminal proBNP), total BNP (proBNP+mature BNP) were prospectively measured HF using specific sensitive enzyme immunochemiluminescent assays. An estimated...
Indoxyl sulfate (IS) is associated with either chronic kidney disease or renal failure, which may predict cardiovascular events via cardiorenal syndrome. The present study aimed to elucidate whether the plasma levels of IS can occurrence in patients heart failure (CHF) and investigate causes CHF leading are highly influenced by levels. We measured 165 [valvular disease: 78, dilated cardiomyopathy: 29, hypertrophic cardiomyopathy (HCM): 25 others: 33] admitted our hospital 2012, we followed...
Abstract Upper-ocean salinity variation in the tropical Pacific is investigated during 2000s, when Triangle Trans-Ocean Buoy Network (TRITON) buoys and Argo floats were deployed more data observed than previous periods. This study focuses on upper-ocean variability warming period of El Niño–Southern Oscillation (ENSO)-like quasi-decadal (QD)-scale sea surface temperature anomalies over central equatorial (January 2002–December 2005; hereafter “warm QD phase”). It shown that strong negative...
[1] The cooperative Indian Ocean experiment on intraseasonal variability in the Year 2011 (CINDY2011) was conducted to capture atmospheric and oceanic characteristics of Madden-Julian Oscillation (MJO) central from late early 2012. During CINDY2011, research vessel (R/V) MIRAI stayed at 8°S, 80.5°E for two months during special observing period (SOP). Intraseasonal convection associated with MJO organized October November SOP. In middle November, both sea surface temperature (SST) mixed...
