Mesenchymal stem cells (MSCs) promote therapeutic angiogenesis to cure serious vascular disorders. However, their survival period and cytokine-secretory capacity are limited. Although hepatocyte growth factor (HGF) can accelerate the rate of angiogenesis, recombinant HGF is limited because its very short half-life (<3-5 minutes). Thus, continuous treatment with required obtain an effective response. To overcome these limitations, we produced genome-edited MSCs that secreted upon...
Recently, the stem cell-derived secretome, which is set of proteins expressed by cells and secreted into extracellular space, has been demonstrated as a critical contributor for tissue repair. In this study, we have produced two sets high concentration secretomes from adipose-derived mesenchymal (ADSCs) that contain bovine serum or free exogenous molecules. Through proteomic analysis, elucidated related to matrix organization growth factor-related are highly ADSCs. Additionally, application...
The climate-induced decrease in fish catches South Korea has been a big concern over the last decades. increase sea surface temperature (SST) due to climate change led not only decline fishery landings but also shift fishing grounds of several species. habitat suitability index (HSI), reliable indicator capacity habitant support selected species, widely used detect and forecast ground formation. In this study, catch data chub mackerel satellite-derived environmental factors were calculate...
Abstract. The in situ primary production rates and various environmental variables were investigated the Chukchi Sea during RUSALCA expedition, which was conducted 2012, to identify current status of production. A 13C–15N dual-tracer technique used measure daily rates, ranged from 0.02 1.61 g C m−2 d−1 (mean ±SD = 0.42 ± 0.52 d−1). showed large regional differences, with southern region (0.66 0.62 d−1) producing approximately 5 times as much northern (0.14 0.10 d−1), primarily due...
Exosomes are nanosized vesicles commonly found in biological fluids as a result of secretion process involving endosomes and multivesicular bodies. The isolation analysis exosomes can be useful for noninvasive clinical diagnosis variety human diseases. We investigated the utility analyzing exosomal proteins, using matrix-assisted laser desorption/ionization combined with Fourier-transform ion cyclotron resonance mass spectrometry (MALDI-FTICR-MS), means determining presence exosomes....
The Changjiang River discharges substantial freshwater into the East China Sea, forming Diluted Water (CDW), a low-salinity plume that influences regional hydrography, nutrient distribution, and marine ecosystems. CDW intrusions Korean coastal waters can cause abrupt salinity temperature changes, impacting fisheries promoting harmful algal blooms. Climate change-driven variations in precipitation have altered discharge patterns, increasing uncertainties its behavior impacts on environment....
The sinapinic acid (SA) matrix has frequently been used for protein analysis in matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS). However, the SA does not result formation of distinctive multiple charge states, whereas 2-nitrophloroglucinol (2-NPG) is capable this. states MALDI-MS proteins advantageous that it results higher accuracy. In this study, mass spectra several common standard proteins, namely cytochrome c, myoglobin, bovine serum albumin (BSA), and...
Sensitive strain sensors (an important component of soft robotics, wearable devices, and biomedical electronics) with high sensitivity, stretchability, long-term stability are still challenging. A sensitive, stretchable, sustainable sensor using poly(3,4-ethylenedioxythiophene) (PEDOT) coated cellulose nanocrystals (CNC) poly(vinyl alcohol)/glycerol (PVA/Gly) composite is proposed. The low cost PEDOT CNC aspect ratio lowered the electrical percolation threshold that significantly improved...
Abstract Understanding the partitioning of primary production into new and regenerated productions, based on nitrate or ammonium utilization, is crucial to understanding biogeochemical processes marine ecosystems. This study addresses scarcity information productions in Yellow Sea (YS), South (SS), East/Japan (EJS). Employing 13 C– 15 N tracer method, we quantified carbon nitrogen uptake rates phytoplankton across four seasons 2018. Seasonal exhibited distinct ranges YS (0.2–6.1 0.4–22.3 mg...
Abstract. The biochemical composition of particulate organic matter (POM) produced through phytoplankton photosynthesis is important in determining food quality for planktonic consumers as well the physiological conditions phytoplankton. Major environmental factors controlling were seasonally investigated Gwangyang Bay, South Korea, which has only natural (e.g., no artificial dams). Water samples compositions obtained from three different light depths (100, 30, and 1 %) mainly at sites Bay...
Adipose tissue is the key organ coordinating whole-body energy homeostasis. Although it has been reported that ring finger protein 20 (RNF20) regulates lipid metabolism in liver and kidney, roles of RNF20 adipose have not explored. Here, we demonstrate promotes adipogenesis by potentiating transcriptional activity peroxisome proliferator–activated receptor-γ (PPARγ). Under normal chow diet feeding, Rnf20 defective (Rnf20+/−) mice exhibited reduced fat mass with smaller adipocytes compared...
Dramatic environmental changes have been recently reported in the Yellow Sea (YS), South of Korea (SS), and East/Japan (EJS), but little information on regional primary productions is currently available. Using 13C-15N tracer method, we measured YS, SS, EJS for first time 2018 to understand current status marine ecosystems three distinct seas. The mean daily during observation period ranged from 25.8 607.5 mg C m−2 d−1 68.5 487.3 106.4 490.5 EJS, respectively. In comparison with previous...
