Dysregulation of liver sinusoidal endothelial cell (LSEC) differentiation and function has been reported in alcohol-associated disease (ALD).Impaired nitric oxide (NO) production stimulates LSEC capillarization dysfunction; however, the mechanism underlying NO remains unclear.Here, we investigated role thioredoxin-interacting protein (TXNIP), an important regulator redox homeostasis, its subsequent effects on ALD progression.We found that hepatic TXNIP expression was upregulated patients...
In an effort to mitigate carbon emissions, the shift towards renewable energy sources and electric vehicles is accelerating. However, for developing nations grappling with basic electricity provision, this transition appears be a long-term goal. This study investigates deployment of micro-off-grid power systems in regions lacking access, exploring their integration motorcycles within holistic development framework enhance overall quality life. The configuration facilitated collection data on...
To improve the NO2-sensing performance of single-walled carbon nanotube (SWCNT)-based sensors, zinc oxide (ZnO) nanoclusters (NCs) were functionalized by a microwave (MW)-assisted synthesis technique. Gas sensors based on pristine SWCNTs and ZnO NC-SWCNT composites synthesized using different weight ratios (ZnO/SWCNTs = 0.5:1, 1:1, 2:1, 3:1) fabricated, their ability to sense various gases at room temperature (25 °C) was investigated. The results showed that sensing composite with ratio 1:1...
Abstract A lightweight 200‐W direct methanol fuel cell (DMFC) stack was developed to power a small‐scale unmanned aerial vehicle (UAV). To reduce the weight and volume of DMFC stack, carbon‐composite bipolar plates were fabricated using natural graphite, phenolic resin, carbon black. In addition, end plates, bolts, nuts polyetheretherketone (PEEK) materials. The which designed for small UAV operating under cruising conditions, consisted 33 cells, in membrane‐electrode assemblies (MEAs) with...
Abstract Background Gastric cancer (GC) is a common malignancy worldwide, with major attribution to Helicobacter pylori . Interleukin (IL)-17A has been reported be up-regulated in serum and tumor of GC patients, but the precise mechanisms underlying its involvement gastric tumorigenesis are yet established. Here, we investigated roles IL-17A pathogenesis H. -induced GC. Methods was induced knockout (KO) wild-type (WT) mice via N -methyl- -nitrosourea (MNU) treatment infection. At 50 weeks...
In this study, we aimed to investigate quantitative differences in performance terms of comparing the automated classification deep vein thrombosis (DVT) using two categories artificial intelligence algorithms: learning based on convolutional neural networks (CNNs) and conventional machine learning. We retrospectively enrolled 659 participants (DVT patients, 282; normal controls, 377) who were evaluated contrast-enhanced lower extremity computed tomography (CT) venography. Conventional...
This study compared the responses of Pd-functionalized and pristine titanate (TiO2) nanotube arrays to ethanol with those acetone determine effects functionalization TiO2 nanotubes Pd nanoparticles on sensitivity selectivity. The gas at 200 °C were ~2877% ~21,253%, respectively. On other hand, 250 ~1636% 8746% In case sensing, response recovery times (10.2 7.1 s) obviously shorter than (14.3 8.8 s), contrast, in sensing (42.5 19.7 almost same as (47.2 17.9 s). showed strongest was most...
Early diagnosis of deep venous thrombosis is essential for reducing complications, such as recurrent pulmonary embolism and thromboembolism. There are numerous studies on enhancing efficiency computer-aided diagnosis, but clinical diagnostic approaches have never been considered. In this study, we evaluated the performance an artificial intelligence (AI) algorithm in detection iliofemoral computed tomography angiography lower extremities to investigate effectiveness using approach during...
To evaluate the safety, efficacy, and long-term outcome of bronchial artery embolization (BAE) in treatment non-massive hemoptysis prognostic factors associated with recurrent bleeding.From March 2005 to September 2014, BAE was performed 233 patients hemoptysis. All had a history persistent or despite conservative medical treatment. We assessed technical clinical success, recurrence, related bleeding, recurrence-free survival rate, additional treatment, major complications all...
The current status of buildings and roads is an essential element land monitoring management, used in various fields such as urban planning, disaster change detection.With the recent advancement deep learning technology, high-performance semantic segmentation techniques have become commonplace, research on applying them to building road detection has begun be actively conducted.However, most these studies are conducted overseas, so there still limitations Korean field.Therefore, this study,...
In this paper, a novel silicon nanowire photodetector on flexible substrate is presented for replacing the function of photoreceptors in retina to restore vision blind. An extremely high surface-to-volume-ratio characteristic capable developing highly-sensitive photonic sensors. Therefore, can be used as stand-alone visual perception device without an external camera. The first fabricated rigid substrate, and then transferred fit curvature eyeball. Experimental results using show very...
WO3-coated multiwall carbon nanotubes (MWCNTs) were fabricated by sputter-deposition of WO3 on MWCNT paste. The outer diameters MWCNTs ranged from 20 to 40 nm and the lengths up a few tens micrometers. low-magnification TEM image typical CNT showed with an inner diameter ~20 tube wall thickness ~7 shells 10 at both edges tube. very nonuniform in not only along axis nanotube but also one other. sensing properties multiple networked sensors toward NO2 gas examined. responses 120-221% over...
