While endomyocardial biopsy (EMB) is recommended in adult patients with fulminant myocarditis, the clinical impact of its timing still unclear.Data were collected from 419 clinically suspected myocarditis admitted to intensive care units across 36 tertiary centres 15 countries worldwide. The diagnosis was histologically proven 210 (50%) patients, either by EMB (n = 183, 44%) or autopsy/explanted heart examination 27, 6%), and cardiac magnetic resonance imaging confirmed 96 (23%) patients....
1. Doxorubicin exhibited dose-independent pharmacokinetics after intravenous (5-20 mg/kg) and oral (20-100 administration to rats. Nearly all (82.1-99.7%) of the orally administered doxorubicin remained unabsorbed, hepatic first-pass extraction ratio bioavailability were approximately 0.5% 1%, respectively. Based on these results, it is likely that primary factor responsible for low limited intestinal absorption, rather than CYP3A4-mediated metabolism. 2. Moreover, in vitro transport...
Objective: Lyophilized microparticles composed of budesonide (BDS), hydroxypropyl-β-cyclodextrin (HP-β-CD), and hydroxypropylmethylcellulose (HPMC) or sodium carboxymethylcellulose (CMC-Na) were developed for intranasal delivery their characteristics evaluated.Materials methods: The particle size morphology assessed by mean diameter measurement scanning electron microscopy (SEM) image, respectively. solid-state products was tested X-ray powder diffraction (XRPD), Fourier transform infrared...
Abstract The detection of Epstein–Barr virus (EBV) in gastric cancer patients is crucial for clinical decision making, as it related with specific treatment responses and prognoses. Despite its importance, the limited medical resources preclude universal EBV testing. Herein, we propose a deep learning-based prediction method from H&E-stained whole-slide images (WSI). Our model was developed using 319 H&E stained WSI (26 positive; TCGA dataset) Cancer Genome Atlas, 108 (8 ISH an...
<TEX>$CuInS_{2}$</TEX> nanoparticles were synthesized by a simple sonochemical method; First, Cu prepared from in methanol solution one pot reaction through the sonochemistry under multibubble sonoluminescence (MBSL) conditions. Second, resulting treated with <TEX>$InCl_3{\cdot}4H_2O$</TEx> and <TEX>$CH_3CSNH_2$</TEX> (thioacetamide) at same MBSL conditions to synthesize <TEX>$In_2S_3$<TEX>-coated solution. Then, they transformed into (CIS) of 20 <TEX>$\sim$</TEX> 40 nm size diameter thermal...
We introduce a multiple conjugation biquandle, and show that it is the universal algebra for defining semi-arc coloring invariant handlebody-links. A biquandle generalization of quandle. extend notion $n$-parallel operations any integer $n$, gives with them.
In this study, we performed laser cleaning using a Q-switching fiber to remove the shop-primer paint and oxide layer. An analysis of surface cleaned by was carried out at various energy densities. The results showed that layer on steel not removed relatively low density, whereas base metal damaged under excessive density. We confirmed it essential select an appropriate density for efficiently removing only without damaging in cleaning.
In the shipbuilding and marine fields, pre-treatment of painted surfaces for cleaning creates environmental pollution problems. Laser is an eco-friendly surface process which selectively removing contaminants on a by vaporizing them with laser beam. this study, pulse was employed to clean shop primer epoxy steel plates. The evaporation characteristics two paints were analyzed according number scans. It determined that removal paint, has relatively low point, higher than paint. addition,...
It is well known that surface-links in [Formula: see text]-space can be presented by diagrams on the plane of text]-valent spatial graphs with makers vertices, called marked graph diagrams. In this paper, we extend method presenting to immersed surface-links. We also give some moves preserve ambient isotopy classes their
Laser cleaning technologies have been attracting attention as a solution to the environmental problems caused by pre-treatment processes, but there are very few studies on removal of paint using laser cleaning. In this study, was performed steel painted with shop primer and epoxy Q-switching fiber laser, characteristics cleaned surfaces compared in relation pulse overlap rate, main parameter. Experimental results showed that number scans remove decreased rate increased. At rates 20â % 50â...
Shipyards are very interested in improving their working environment and resolving environmental pollution issues by replacing mechanical cleaning technologies used before after painting processes with laser technology. Because epoxy paint is thickly coated, a thickness of 200 μm or greater, it difficult to remove using both technologies. Therefore, this study tried obtain effective results controlling the process parameters when removing thick coating Q-switching fiber system an average...
Underwater acoustic communication can be applied to many fields, such as oceanic data collection, undersea exploration, disaster prevention, underwater environmental monitoring, and tactical surveillance. monitoring system is one of basic technologies in these application fields. Therefore, there a growing need for researching systems. systems should designed differently from terrestrial wireless because the special characteristics environment, bandwidth limitations, multi-path propagation,...
In this paper, we introduce the (co)homology group of a multiple conjugation biquandle. It is prismatic chain complex, which related to homology foams introduced by J. S. Carter, modulo certain subchain complex. We construct invariants for [Formula: see text]-oriented handlebody-links using text]-cocycles. When biquandle text] obtained from text]-parallel operations, provide text]-cocycle (or text]-cocycle) equipped with an text]-set text].
레이저 클리닝은 친환경적, 고정밀, 자동화 및 비접촉식 공정 등과 같은 많은 장점으로 인하여 다양한 산업분야에 적용되어왔다. 최근에는 자동차, 우주항공, 조선해양 산업 등에서 대면적의 표면 전처리 기술에 클리닝을 적용하고자 하는 수요가 늘어나면서 이에 대한 연구가 활발하게 진행되고 있다. 따라서 본 연구에서는 에폭시 도장면의 제거를 위한 클리닝 시 주요 변수인 펄스 중첩률과 패스 중첩률에 따른 특성 효율을 연구하였다. 실험 결과, 상대적으로 높은 중첩률 조건에서는 입열량의 증가로 제거량이 높게 나타났으나 느린 스캔 속도로 효율이 낮아지는 것을 확인할 수 있었다. 레이저와 재료의 짧은 상호작용 시간에 도장면만을 효율적으로 제거할 있는 변수의 선정이 중요함을 알
While producing gas fuel supply pipes for duel (DF) engines, a welding process is essential. Accordingly, specimen management before and after crucial to obtain highly reliable weldments. In this study, we developed an environmentally friendly laser cleaning technology address toxic work environment environmental pollution problems caused by chemical utilized in post-welding treatment of DF engines. An experiment was conducted implementing surface the butt fillet weldment specimens according...
We report a rare and severe nasal presentation of antiphospholipid syndrome in 41-year-old man with systemic lupus erythematosus end-stage renal disease. His signs included total septal necrosis, along external swelling erythema. Prior to the correct diagnosis, multiple medical surgical treatments were attempted without success. After initiation intravenous immunoglobulin anticoagulation therapy, his symptoms promptly resolved. The complication is relatively unknown finding limited...
본 연구는 건강의 사회적 결정요인의 관점에 기반하여 박탈이 우울에 미치는 영향을 살펴보고, 박탈과 우울의 관계에서 고립의 매개효과를 검증하는 것을 목적으로 한다. 이를 위해 2010년 서울시 복지패널조사 자료의 만 18세 이상 65세 미만 성인 4,592명을 대상으로 우울과의 관계를 분석하고 검증하였으며, 성별을 기준으로 집단을 구분하여 매개효과분석을 실시하였다. 연구결과, 박탈은 고립과 정적인 것으로 나타났다. 고립이 분석한 결과, 고립은 부분매개효과를 갖는 확인되었다. 성별 비교를 남성과 여성 집단에서 각각 박탈, 집단 모두에서 유의한 미쳤고, 분석되었다. 하지만 성별에 따라 변수들과 변수들의 영향력 정도에서 차이가 연구결과는 적절하게 개입하고 예방하기 위해서는 결정요인인 박탈을 완화시킬 수 있는 제도적 개선과 고립을 예방할 지원이 필요하다는 함의를 제공한다. 또한 다르게 나타나는 대한 이해를 기반으로 하는 실천이 점을 강조한다.
