Objective There are conflicting results among previous studies regarding the prognosis of heart failure with preserved ejection fraction (HFpEF) compared reduced (HFrEF). This study aimed to compare outcomes patients de novo acute (AHF) or decompensated HF (ADHF) according HFpEF (EF≥50%), HFrEF (EF<40%) and define mid-range EF (HFmrEF, 40≤EF<50%). Methods Between March 2011 February 2014, 5625 consecutive AHF were recruited from 10 university hospitals. A total 5414 (96.2%) data...
This study sought to examine the impact of door-to-diuretic (D2D) time on mortality in patients with acute heart failure (AHF) who were presenting an emergency department (ED). Most AHF present congestion. Early decongestion diuretic agents could improve their clinical outcomes. The Korea Acute Heart Failure registry enrolled 5,625 consecutive hospitalized for AHF. For this analysis, included received intravenous within 24 h after ED arrival. and delayed groups defined as D2D ≤60 min >60...
In this work, the chronoamperometry-based redox cycling of 3,3',5,5'-tetramethylbenzidine (TMB) was performed by using interdigitated electrode (IDE). The signal obtained from two sequential chronoamperometric profiles: (1) with generator at oxidative potential TMB and collector reductive TMB, (2) TMB. (dual mode) showed a sensitivity 1.49 μA/OD, efficiency estimated to be 94% (n = 10). sensitivities conventional same chronoamperometry single working (single were 0.67 μA/OD 0.18...
An electrochemical capacitance immunosensor based on an interdigitated wave-shaped micro electrode array (IDWµE) for direct and label-free detection of C-reactive protein (CRP) was reported. A self-assembled monolayer (SAM) dithiobis (succinimidyl propionate) (DTSP) used to modify the antibody immobilization. The SAM functionalized characterized morphologically by atomic force microscopy (AFM) energy dispersive X-ray spectroscopy (EDX). nature gold-sulfur interactions SAM-treated probed...
Clinical Features of Right-Sided Infective Endocarditis Occurring in Non-Drug UsersRight-sided infective endocarditis (RIE) occurs predominantly intravenous drug users western countries, and it has a relatively good prognosis.Clinical features prognosis RIE occurring non-drug are not well known.We investigated the clinical findings users.We retrospectively reviewed 345 cases diagnosed with IE.Cases or left-sided (LIE) defined by vegetation site were included having no both-side...
Background Although current guidelines now define heart failure with midrange ejection fraction ( HF mr EF ) as a left ventricular of 40% to 49%, there are limited data on response guideline‐directed medical therapy in patients . The study aimed evaluate the association between β‐blocker, renin‐angiotensin system blocker RASB ), or aldosterone antagonist AA treatment clinical outcome Methods and Results We performed patient‐level pooled analysis 1144 who were hospitalized for acute from Kor...
A green to orange emitting nitridosilicate based phosphor was developed for white-LED application. Observed broad-band emission in range is originated from Eu2+ and Yb2+-trap site of double doped SrSi2O2N2:Eu2+,Yb2+ phosphor. Energy transfer between activator ions confirmed by measuring decay time the green-emission as energy donor. The effect co-doping different ratio on photoluminescence properties studied. Emission obtained function ion contents, increasing Yb2+ concentration, red...
It is unknown whether different β-blockers (BBs) have variable effects on long-term survival of patients with heart failure reduced ejection fraction (HFrEF). This study compares the two BBs, carvedilol and bisoprolol, in HFrEF.The Korean Acute Heart Failure (KorAHF) registry a prospective multicenter cohort that includes 5,625 who were hospitalized for acute (AHF). We selected 3,016 HFrEF divided this population into groups: BB at discharge (n = 1,707) or no 1,309). Among discharge,...
Electrical cell-substrate impedance sensing is increasingly being used for label-free and real-time monitoring of changes in cell morphology number during growth, drug screening, differentiation. In this study, we evaluated the feasibility using ECIS to monitor C2C12 myoblast differentiation a fabricated indium tin oxide (ITO) electrode-based chip. on ITO electrode was validated based decreases mRNA level MyoD increases levels myogenin myosin heavy chain (MHC). Additionally, MHC expression...
