The objective of this research was to access the determination metabolite profiles and antioxidant properties in leaves green perilla (Perilla frutescens), where these are considered functional nutraceutical substances Korea. A total 25 compositions were confirmed as six phenolic acids, two triterpenoids, eight flavonoids, seven fatty glucosides using an ultra high performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry...
Methylmercury (MeHg) accumulation in marine organisms poses serious ecosystem and human health risk, yet the sources of MeHg surface subsurface ocean remain uncertain. Here, we report first mass budgets for Western Pacific Ocean estimated based on cruise observations. We found major net source water to be vertical diffusion from layer (1.8–12 nmol m–2 yr–1). A higher upward North (12 yr–1) than Equatorial (1.8–5.7 caused elevated concentrations observed Pacific. furthermore that slope linear...
Abstract Highly sensitive rapid testing for COVID-19 is essential minimizing virus transmission, especially before the onset of symptoms and in asymptomatic cases. Here, we report bioengineered enrichment tools lateral flow assays (LFAs) with enhanced sensitivity specificity (BEETLES 2 ), achieving SARS-CoV-2 viruses, nucleocapsid (N) proteins immunoglobulin G (IgG) 3-minute operation. The limit detection improved up to 20-fold. We apply this method clinical samples, including 83% either...
The development of nonbleachable colorants made safe and inexpensive materials is a scientifically important task in view future environmental biological impacts. In this study, the conditions under which spherical colloidal crystals (photonic balls) formed mainly sub-micron-sized monodispersed silica fine particles carbon black exhibit vivid structural coloring were systematically investigated. (111) plane face-centered cubic crystal by oriented on surface photonic balls from particles. As...
Obesity is known to increase the risk and severity of age-related macular degeneration (AMD). Increased inflamed metabolic activity visceral adipose tissue (VAT) considered as a crucial underlying mechanism for harmful effects obesity. In this study, we aimed investigate VAT with
In this paper, a fast re-coloring method with information preserving is proposed for the color-blind (CB) who experiences difficulty to discriminate some color differences. algorithm, we utilize new transform that can enhance perceptibility CB while maintaining re-colored image as natural possible normal viewer. addition, an improved which effectively detects unperceivable (CBU) colors be introduced. Experimental results show produce more comprehensible images viewers naturalness of...
Colorimetric glucose sensors using enzyme-coronated gold nanoparticles have been developed for high-throughput assays to monitor the blood levels of diabetic patients. Although those shown sensitivity and wide linear detection ranges, they suffer from poor selectivity stability in detecting glucose, which has limited their practical use. To address this limitation, herein, we functionalized glucose-oxidase-coronated with an erythrocyte membrane (EM-GOx-GNPs). Because (EM) selectively...
Daltonization is a procedure of color adaptation in an image to improve the perception for color-blind viewer. This paper presents fast daltonization algorithm protanopes who cannot distinguish between red and green. In proposed algorithm, protanope-unperceptible (PU) colors are identified then converted into new protanope-perceptible (PP) by method that utilizes clustering rapidly measure similarity. Experimental results indicate performs better than conventional terms both perceptibility...
Classification of sleep stages is important for diagnosis and treatment disorder. Manual classification performed by experts burdensome time-consuming. This study proposes a novel model stage classification. EEG EOG signals 153 healthy subjects was used. The proposed ensembles two EEGNet-BiLSTM models which learn respectively. Compared to the existing models, yielded approximately 82% accuracy 0.78 k-value, whereas ensemble showed 90% 0.80 k-value. superior in terms consistency compared...
The oral microbiome is closely associated with systemic diseases, indicating the presence of bacteremia and inflammatory mediators in circulation. Our research aims to investigate relationship between other microbial habitats. We analyzed 180 specimens from 36 patients, including saliva, buccal swab, plaque, stool, blood samples a healthy group (Non_PD, n = 18) periodontitis (PD, 18). final analysis included 147 specimens, varying sample sizes for each group. Metagenomic was performed using...
To understand the bioconcentration of methylmercury (MeHg) at base riverine food chain, we determined levels dissolved organic carbon, microseston, Hg, and MeHg in surface water relation to microzooplankton from Yeongsan River. The spatial distribution unfiltered Hg (0.29-3.1 ng/L) (0.15-0.74 closely followed microseston distribution. (0.0078-0.077 (0.0069-0.018 increased with increasing distance river mouth appeared arise shallow wetlands surrounding upper riverbanks then be transported...

Various image re-coloring methods have been developed to enhance the perceptibility of for color-blind. Recently, some proposed produce re-colored images that are not only visually perceptible color deficient viewers but also look natural normal observer. However, impractical apply consumer devices due its high complexity. Therefore, in this paper, an efficient method utilizes clustering is proposed. The detects important region further images. Experimental results show can provide more...
