Article The ameliorative effects of capsidiol isolated from elicited Capsicum annuum on mouse splenocyte immune responses and neuroinflammation Capsidiol, is an anti-fungal phytoalexin produced by plants of Solanaceae. Capsidiol was examined in cultures of primary splenocytes (SPLCs) isolated from healthy C57BL/6 mice and from those with induced experimental autoimmune encephalomyelitis (EAE) as a mouse model for autoimmune neurodegenerative multiple sclerosis (MS). We also examined the impact of capsidiol in IFN-gamma-stimulated mouse BV2 microglial cells. Capsidiol resulted in a significant reduction in the anti-CD3/CD28 (alpha CD3/CD28)-induced IFN-gamma(+)CD4(+) (Th1) and IFN-gamma(+)CD8(+) (Tc1) populations as well as in the production of cytokines (IFN-gamma, IL-17A, IL-6, IL-2, TNF-alpha, and IP-10). Specifically, the CD4(+) and CD8(+) populations (T-bet(+)IFN-gamma(-), T-bet(+)IFN-gamma(+), and T-bet(-)IFN-gamma(+)) and cytokine production mediated by Th1/Tc1 polarization were diminished by 25 mu M capsidiol. MOG(35-55) restimulation of SPLCs from EAE mice resulted in an increase in antigen-specific T cells, including Th1, IL-17A(+)CD4(+) (Th17), and IL-17A(+)CD8(+) (Tc17) populations. By contrast, capsidiol resulted in a decrease in the proportions of Th17 and Tc17 cells; MOG(35-55)-specific cytokine production was also diminished by capsidiol. Capsidiol treatment resulted in diminished levels of IFN-gamma-induced nitric oxide and IL-6; expression of iNOS and COX-2 were suppressed by 50 mu M capsidiol in IFN-gamma-stimulated BV2 cells. This is the first report of capsidiol-mediated immunomodulatory and antineuroinflammatory activities that may serve to prevent neurodegeneration.

Article Effectiveness of rapid multiplex polymerase chain reaction for early diagnosis and treatment of pertussis Background: Pertussis, is an infectious respiratory disease caused by Bordetella pertussis. The incidence of pertussis has been increasing in South Korea to due to waning vaccine-induced immunity. Culture has a low sensitivity and a long turnaround time (TAT). Recently, a rapid multi-polymerase chain reaction (mPCR) test with a TAT of about 1 h was developed for the detection of respiratory pathogens (17 viruses and three bacteria), including B. pertussis. This study aimed to investigate the effectiveness of mPCR for early diagnosis and treatment of pertussis. Methods: We performed a retrospective study of patients with pertussis diagnosed from May 2017 to June 2019 at a university hospital in South Korea. Nasopharyngeal swab specimens were tested using mPCR. Data were extracted from medical records. Results: A total of 27 patients with a median age of 48.9 years (range: 3.3-82.2 years) were diagnosed with pertussis, of whom 9 (33.3% ) were male. Eleven (40.7%) had fever, 12 (44.4%) had dyspnea, three (11.1%) had paroxysmal cough, and nine (33.3%) had inspiratory whooping. The median interval from symptom onset to diagnosis was 9.0 days (range: 1-31 days). Twenty-four patients (81.5%) were diagnosed within 2 weeks from symptom onset. All but one patient was prescribed macrolide antibiotics. Twenty-two patients (81.5%) required hospitalization, including three (11.1%) who required intensive care unit care for ventilation. Conclusion: Testing patients with respiratory symptoms using mPCR can improve early diag-nosis of pertussis, ensure proper treatment, and may help with outbreak control.

Article Evaluation of growth kinetics of aluminide coating layers on Ti-6Al-4V alloys by pack cementation and the oxidation behaviours of the coated Ti-6Al-4V alloys Ti-6Al-4V(Ti64) alloy has excellent mechanical properties and corrosion resistances, but poor oxidation properties at high temperatures. It is necessary to improve the oxidation resistances of the alloy in order to expand its application in the aerospace and automotive fields. This study aimed to improve oxidation resistances through diffusion coatings on the surface of the alloy. Aluminide coatings on Ti64 alloys have been investigated via pack aluminium process at temperature ranges of 400-800 degrees C. Al and/or TiAl3 layers were formed at the interface between the Ti64 alloy and the Al coating layer, when the Ti64 alloys were heat-treated at 400 and 500 degrees C. TiAl3 layer was manufactured on Ti64 alloys at 600, 700 and 800 degrees C. The growth of the coated TiAl3 layer followed diffusional growth manner, and the estimated value of the nucleation barrier was the lowest among the intermediate phases of the Ti-Al system. The coating kinetics were discussed together with free energy diagram observations. The activation energy for growth of the TiAl3 layer was estimated as similar to 82 kJ/mol in the experimental temperature ranges. At the same time, isothermal oxidation tests of the bare Ti64 alloy and the aluminized Ti64 alloys were performed at 1000 degrees C. By confirming the diffusion pathway of the Ti-Al-O ternary system, the oxidation behaviours and resistances of the alloys were compared and analysed.

Article Chronic inflammation-induced senescence impairs immunomodulatory properties of synovial fluid mesenchymal stem cells in rheumatoid arthritis Background: Although the immunomodulatory properties of mesenchymal stem cells (MSCs) have been highlighted as a new therapy for autoimmune diseases, including rheumatoid arthritis (RA), the disease-specific characteristics of MSCs derived from elderly RA patients are not well understood. Methods: We established MSCs derived from synovial fluid (SF) from age-matched early (average duration of the disease: 1.7 years) and long-standing (average duration of the disease: 13.8 years) RA patients (E-/L-SF-MSCs) and then analyzed the MSC characteristics such as stemness, proliferation, cellular senescence, in vitro differentiation, and in vivo immunomodulatory properties. Results: The presence of MSC populations in the SF from RA patients was identified. We found that L-SF-MSCs exhibited impaired proliferation, intensified cellular senescence, reduced immunomodulatory properties, and attenuated anti-arthritic capacity in an RA animal model. In particular, E-SF-MSCs demonstrated cellular senescence progression and attenuated immunomodulatory properties similar to those of L-SF-MSC in an RA joint-mimetic milieu due to hypoxia and pro-inflammatory cytokine exposure. Due to a long-term exposure to the chronic inflammatory milieu, cellular senescence, attenuated immunomodulatory properties, and the loss of anti-arthritic potentials were more often identified in SF-MSCs in a long-term RA than early RA. Conclusion: We conclude that a chronic RA inflammatory milieu affects the MSC potential. Therefore, this work addresses the importance of understanding MSC characteristics during disease states prior to their application in patients.

Article Development of Na2O-MO-Bi2O3-B2O3-Sm2O3 glasses (MO=Ba/Mg) for laser and scintillation application. Na2O-MO-Bi2O3-B2O3-Sm2O3 glasses (MO=Ba/Mg) were developed for the light emitting materials applications. Four broad emission peaks were observed at transitions 4G5/2 ? 6HJ (J=5/2, 7/2, 9/2 and 11/2). The maximum transition occur at 600 nm. Concentration quenching were observed at 0.5 mol% of Sm3+ ion for both glasses. The X-ray luminescence spectra were found similar to the photoluminescence spectra. The Judd Ofelt (JO) parameters for Sm3+ in the present glasses were procure from the absorption and emission spectra. The important parameters for the laser materials like quantum efficiency, stimulated emission cross section and radiative decay time were explained in detail in the present study. The lifetime were found decreasing with Sm3+-concentration which is the evident of energy transfer between Sm3+ ions. The energy transfer process were further explained by applying IH model. The orange emission from the present glasses were confirmed from CIE chromoticity diagram. According to the present results it is suggested that at 404 nm excitation and 600 nm emission the NMgBiBSm1.0 glass is suitable for the orange emitting devices and from X-ray luminescence emission spectra the present glass might be used for scintillation purpose.

Article How Does Pacific Decadal Oscillation Affect Tropical Cyclone Activity Over Far East Asia? We investigated the relationship between tropical cyclones (TCs) and the Pacific Decadal Oscillation (PDO) over the western North Pacific (WNP) during 1982-2018, focusing on an area surrounding the Korean Peninsula and Japan. The frequency of TCs passing through this area (TCm) in the negative PDO phase was approximately 50% higher than that in the positive phase in September. Higher TC track density was observed around the Korean Peninsula and Japan in the negative PDO phase because the large-scale environments were favorable for TC activity. However, TCm and PDO were not related in August because the location of WNP subtropical high was not significantly different. In addition, large-scale environments, which were associated with TC activity, provided more favorable conditions in September than in August.

Article Luminescence and scintillation properties of Ce3+-doped P2O5-Li2CO3-GdBr3-Al2O3 glasses A series of glass samples were fabricated with the composition of (65-x)P2O5:20Li2CO3:10GdBr3:5Al2O3:xCeBr3 (where, x = 0.5,1,2,3,4). The powder X-ray diffraction measurements were performed to verify the amorphous structure of the prepared glass samples. Energy-dispersive X-ray spectroscopy showed an interesting phenomenon of oxygen bridging eliminating Br (Bromine) from the initial compounds. The luminescence characteristics of the samples were studied using X-rays and UV-Vis excitations. Characteristics Ce3+ emission was observed at 350 nm including energy transfer from 4f energy state of Gd3+ to 5d energy band of Ce3+. The fast decay component was observed as 37 ns, 42 ns, and 44 ns for the UV, alpha-particles, and gamma-ray excitations, respectively. The intermediate and slow components were observed for alpha-particles, and gamma-rays excitations indicating Gd3+ to Ce3+ energy transfer and 4f-4f transitions of Gd3+ -ions accordingly. The scintillation property was studied with alpha-particles using a 241Am source. Ntarisa, Amos Vincent; Saha, Sudipta; Aryal, Pabitra; Kim, H.

Article Slow control and monitoring system at the JSNS² The Sterile Neutrino Search at the J-PARC Spallation Neutron Source (JSNS(2)) experiment aims to search for sterile neutrino oscillations using a neutrino beam from muon decays at rest. The JSNS(2) detector contains 17 tons of 0.1% gadolinium (Gd) loaded liquid scintillator (LS) as a neutrino target. Detector construction was completed in the spring of 2020. A slow control and monitoring system (SCMS) was implemented for reliable control and quick monitoring of the detector operational status and environmental conditions. It issues an alarm if any of the monitored parameters exceed a preset acceptable range. The SCMS monitors the high voltage of the photomultiplier tubes, the LS level in the detector, possible LS overflow and leakage, the temperature and air pressure in the detector, the humidity of the experimental hall, and the LS flow rate during filling and extraction. An initial 10 days of data-taking with a neutrino beam was done following a successful commissioning of the detector and SCMS in 2020 June. In this paper, we present a description of the assembly and installation of the SCMS and its performance. Park, J. S.; Ajimura, S.; Botran, M.; Choi, J. H.; Choi, J. W.; Cheoun, M.

Article Toward improvement of sampling-based seismic probabilistic safety assessment method for nuclear facilities using composite distribution and adaptive discretization As a seismic probabilistic safety assessment (SPSA) method for nuclear facilities, direct quantification of fault tree using the Monte Carlo simulation (DQFM) was developed to accurately consider the partial dependency between components. However, since this is a sampling-based method, there is a disadvantage in that a large number of samples must be extracted for accurate seismic risk estimation. Accordingly, this study develops an efficient SPSA method by improving the existing DQFM method. We replace the method of extracting samples from both seismic response and capacity at each component by that of taking samples only from a single response distribution with a composite deviation. Also, a method of adaptive discretization for seismic intensity (ADSI) is devised by linking the seismic intensity subdivision with the convergence of the final seismic risk. The Monte-Carlo sampling technique is replaced by the Latin hypercube sampling. As an application result to nuclear facilities, the proposed method requires only half samples for every seismic intensity than the existing DQFM method, while the accuracy of results was almost similar. Besides, through the ADSI method, the proposed method was able to secure approximately three times efficiency more than the existing DQFM method, without losing the accuracy of the results.

Article Tunable orange, yellow and white emission of Pr³⁺-doped tungsten gadolinium borate glasses Pr3+ doped WO3-Gd2O3-B2O3 glasses were prepared by the melt quenching technique to study in the luminescence under different excitation. X-ray diffraction (XRD) pattern represents the dominant vitreous disordered structure. The glass with 2.0 mol% of Pr2O3 possess a massive density at 6.15 g/cm(3). The luminescence spectra of Pr3+ doped glasses were recorded under the various excitation wavelengths of visible light and under the electron excitation. The streak camera was used to measure decay time. The developed glasses show tunable luminescence property, orange under 435 and 447 nm excitation, yellow under 471 and 484 nm excitation and white under the electron excitation. The photoand catodoluminescence decay times of glasses are comparable. The optimal concentration of Pr2O3 in the glass is 0.1 mol% that performed the highest emission intensity. This glass can be considered as a new low-cost alternative for the tunable light source and the electron detection material.

Article Impact of wind pattern and complex topography on snow microphysics during International Collaborative Experiment for PyeongChang 2018 Olympic and Paralympic winter games (ICE-POP 2018) Snowfall in the northeastern part of South Korea is the result of complex snowfall mechanisms due to a highly contrasting terrain combined with nearby warm waters and three synoptic pressure patterns. All these factors together create unique combinations, whose disentangling can provide new insights into the microphysics of snow on the planet. This study focuses on the impact of wind flow and topography on the microphysics drawing of 20 snowfall events during the ICE-POP 2018 (International Collaborative Experiment for PyeongChang 2018 Olympic and Paralympic winter games) field campaign in the Gangwon region. The vertical structure of precipitation and size distribution characteristics are investigated with collocated MRR (micro rain radar) and PARSIVEL (particle size velocity) disdrometers installed across the mountain range. The results indicate that wind shear and embedded turbulence were the cause of the riming process dominating the mountainous region. As the strength of these processes weakens from the mountainous region to the coastal region, riming became less significant and gave way to aggregation. This study specifically analyzes the microphysical characteristics under three major synoptic patterns: air-sea interaction, cold low, and warm low. Air-sea interaction pattern is characterized by more frequent snowfall and vertically deeper precipitation systems on the wind-ward side, resulting in significant aggregation in the coastal region, with riming featuring as a primary growth mechanism in both mountainous and coastal regions. The cold-low pattern is characterized by a higher snowfall rate and vertically deep systems in the mountainous region, with the precipitation system becoming shallower in the coastal region and strong turbulence being found in the layer below 2 km in the mountainous upstream region (linked with dominant aggregation). The warm-low pattern features the deepest system: precipitation here is enhanced by the seeder-feeder mechanism with two different precipitation systems divided by the transition zone (easterly below and westerly above). Overall, it is found that strong shear and turbulence in the transition zone is a likely reason for the dominant riming process in the mountainous region, with aggregation being important in both mountainous and coastal regions.

Article Orphan nuclear receptor ERRγ regulates hepatic TGF-β2 expression and fibrogenic response in CCl4-induced acute liver injury Acute liver injury results from the complex interactions of various pathological processes. The TGF-beta superfamily plays a crucial role in orchestrating fibrogenic response. In contrast to TGF-beta 1, a role of TGF-beta 2 in hepatic fibrogenic response has not been fully investigated. In this study, we showed that TGF-beta 2 gene expression and secretion are induced in the liver of CCl4 (1 ml/kg)-treated WT mice. Studies with hepatocyte specific ERR gamma knockout mice or treatment with an ERR gamma-specific inverse agonist, GSK5182 (40 mg/kg), indicated that CCl4-induced hepatic TGF-beta 2 production is ERR gamma dependent. Moreover, IL6 was found as upstream signal to induce hepatic ERR gamma and TGF-beta 2 gene expression in CCl4-mediated acute toxicity model. Over-expression of ERR gamma was sufficient to induce hepatic TGF-beta 2 expression, whereas ERR gamma depletion markedly reduces IL6-induced TGF-beta 2 gene expression and secretion in vitro and in vivo. Promoter assays showed that ERR gamma directly binds to an ERR response element in the TGF-beta 2 promoter to induce TGF-beta 2 transcription. Finally, GSK5182 diminished CCl4-induced fibrogenic response through inhibition of ERR gamma-mediated TGF-beta 2 production. Taken together, these results firstly demonstrate that ERR gamma can regulate the TGF-beta 2-mediated fibrogenic response in a mouse model of CC1(4)-induced acute liver injury.

Article Prussian blue analogues as platform materials for understanding and developing oxygen evolution reaction electrocatalysts Transition metal based materials containing Fe have drawn great attention as oxygen evolution reaction (OER) catalysts. The nature of the electrocatalytic active species remains under debate due to the ambiguous physicochemical properties of the catalyst materials, such as the oxidation states and crystal structures. Here, in order to address this issue, transition metal Prussian blue analogues (TM-PBA, Na(TM)(Fe) (CN)(6), TM = V, Fe, Co, and Ni) with an isomorphous structure are investigated for OER catalysis. Our combined experimental measurements and density functional theory (DFT) calculations reveal that TM-PBAs exhibit volcano-like OER activity with Ni-PBA located near the top of the volcano. Such a volcano-like activity profile can be attributed to the distinctive binding energy difference between *O and *OH on different TM-PBAs surfaces. This work demonstrates that TM-PBAs can be used as platform materials for understanding structure-property-activity relationships in OER catalysts. (C) 2020 Elsevier Inc. All rights reserved.

Article Synergistic metal-oxide interaction for efficient self-reconstruction of cobalt oxide as highly active water oxidation electrocatalyst Developing catalysts with outstanding performance for oxygen evolution reaction (OER) is crucial to advance energy conversion technologies. In these regards, catalysts based on 3d transition metals have recently attracted much attention, yet further development is required. Here, we present a new type of heterostructure catalyst in which CoO nanowire arrays are hybridized with tungsten nanoparticles (W-CoO), and are self-supported on conductive carbon cloth (CC). Electronic coupling effects at the W-CoO heterointerface promote electron transfer and OER kinetics to expedite the formation of oxyhydrox-ide species, which are the active sites for OER processes. A variety of in situ and ex situ characterization methods are employed to reveal deep insights into surface transformations and investigate the relation-ship between the conversion to oxyhydroxide moieties and OER performance. This report presents new understanding of the rational design and synthesis of catalysts that exhibit outstanding performance as electrochemical water splitting electrode for OER.
