Abstract Composites of multiwall carbon nanotubes (MWCNTs) and sulfonated polyaniline (SPAN) were prepared through the oxidative polymerization a mixture aniline, 2,5‐diaminobenzene sulfonic acid, MWCNTs. Fe, Pd, or Fe–Pd alloy nanoparticles embedded into MWCNT–SPAN matrix by reduction Fe Pd ions with γ radiation. Sulfonic acid groups emeraldine form backbone units in SPAN served as source for metal presence The existence metallic/alloy particles was further ascertained characterization...
Aims This study aimed to develop and validate deep-learning-based artificial intelligence algorithm for predicting mortality of AHF (DAHF). Methods results 12,654 dataset from 2165 patients with in two hospitals were used as train data DAHF development, 4759 10 enrolled the Korean registry performance test data. The endpoints in-hospital, 12-month, 36-month mortality. We compared Get Guidelines–Heart Failure (GWTG-HF) score, Meta-Analysis Global Group Chronic Heart (MAGGIC) other...
Abstract Androgen and androgen receptor (AR)–mediated signaling are crucial for the development of prostate cancer. Identification novel naturally occurring phytochemicals that target AR from Oriental medicinal herbs holds exciting promises chemoprevention this disease. In article, we report discovery strong long-lasting antiandrogen activities ethanol extract a herbal formula (termed KMKKT) containing Korean Angelica gigas Nakai (AGN) root nine other in androgen-dependent LNCaP human cancer...
Heteroatom doping is a powerful means to tune the optical and electronic properties of gold clusters at atomic level. We herein report that Au38 cluster with Pt Pd atoms leads core-doped [Pt2Au36(SC6H13)24]2– [Pd2Au36(SC6H13)24]0, respectively. Voltammetric investigations show these exhibit drastically different structures; whereas HOMO–LUMO gap found be 0.95 V, [Pd2Au36(SC6H13)24]0 decreased 0.26 suggesting Jahn–Teller distortion 12-electron cluster. Density functional confirm Pd-doped...
A wide variety of information technology (IT) services will become available for vehicles through the IEEE 802.11p, 1609, and wireless access in vehicular environment (WAVE) standards, naturally need service handover a necessity. For WAVE networks, time coordinated medium control (MAC) protocol named point coordination function (WPCF) is proposed this paper. The mathematical derivations simulation analysis demonstrate that WPCF can significantly enhance utilization efficiency support more...
The aim of this study was to evaluate after more than 5 years the outcome surgical treatment for flexible idiopathic scoliosis using skipped pedicle screw fixation.For patients with spine curves < 90° and flexibility > 20%, screws had been inserted into every other segment on corrective side 2-4 per curve supportive side. authors analyzed results in 57 patients, including correction rate coronal curvature rotational deformity, loss, sagittal balance, complications, blood operation time,...
Porous β-calcium pyrophosphate (β-CPP) was developed to improve the fusion success of posterolateral lumbar (PLF). The possibility accomplishing PLF using a mixture porous β-CPP and iliac bone studied. This paper reports radiologic results plus autograft for degenerative disease as graft extender.A prospective, case-matched, radiographic study evaluating short segment performed compare efficacy with that an alone fusion. Thirty one consecutive patients (46 levels) underwent pedicle screw...
Mesenchymal stem cells (MSCs) in the bone marrow and other somatic tissues reside an environment with relative low oxygen tension. Cobalt chloride (CoCl2) can mimic hypoxic conditions through transcriptional changes of some genes including hypoxia-inducible factor-1α (HIF-1α) vascular endothelial growth factor (VEGF). This study evaluated potential role CoCl2 preconditioning on multi-lineage differentiation C3H/10T1/2, a murine MSC line to understand its possible molecular mechanisms vitro....
Aims In 2021, vericiguat was approved by the US Food and Drug Administration (FDA) European Commission (EC) for reducing cardiovascular mortality heart failure (HF) hospitalizations in patients with HF reduced ejection fraction (HFrEF) based on Vericiguat Global Study Subjects Heart Failure Reduced Ejection Fraction (VICTORIA) trial. However, there has been no report characterizing generalizability of to real-world clinical practice. Methods results The Korean Acute (KorAHF) registry is a...
To investigate the morphological characteristics of dome-shaped macula (DSM) and inferior staphyloma complicated by serous retinal detachment (SRD). Electronic medical records multimodal images patients diagnosed with DSM were retrospectively reviewed. Morphological features, including axial length, curvature height, orientation dome, presence pigment epithelial detachment, choroidal vascular features such as subfoveal thickness, variations in abrupt changes thickness large vessels analyzed....
Abstract We propose an active‐switching light‐field (LF) camera system that significantly extends the measurable depth range over conventional passive‐optics‐based LF systems by integrating a stacked geometric phase lens (GPL) module in compact design. During elemental image acquisition and rendering, chromatic aberration focus‐tunable GPL is compensated adjusting reconstruction magnification for each color channel. Additionally, optimal operation sets are selected based on color‐dependent...
We investigated the implications of SerpinA3, a secretory serine protease inhibitor, in inflammation and adipogenesis Graves' orbitopathy (GO). To identify its precise function GO pathogenesis, we evaluated role SerpinA3 GO. expression was compared between (n = 30) normal participants 28) orbital tissue explants using real-time PCR. Orbital fibroblasts from 3) were transfected with or without small interfering RNA against before IL-1β stimulation. Western blotting assessed inflammatory...
Abstract We reduced image noise in broadband full‐color holographic capture a compact self‐interference incoherent digital holography (SIDH) system by combining cholesteric liquid crystal (CLC) circular polarizer with quarter‐waveplate‐based geometric phase lens (QW‐GPL). To address chromatic wavefront issues commonly found conventional half‐waveplate‐based SIDH systems, we explore incorporating GPL In particular, resolve angular polarization‐dependent QW‐GPL modulation utilizing circularly...
Abstract OBJECTIVES The aims of this study were to evaluate the changes in myocardial single photon emission computed tomography results after coronary artery bypass grafting, and examine segments with persistent perfusion defect preoperatively patients who underwent grafting having all patent grafts at 1-year postoperatively. METHODS Patients complete revascularization, assessed by preoperative, postoperative 3- 12-month tomography, showed angiograms included. Stress rest imaging was...
To evaluate the long-term outcomes of immunosuppressive therapy in patients with autoimmune retinopathy (AIR) and assess differences based on anti-retinal antibody (ARA) profiles. A retrospective multicenter observational study was conducted 26 AIR who received for at least six months.
