Article Molecular surveillance of rotavirus A associated with diarrheic calves from the Republic of Korea and full genomic characterization of bovine-porcine reassortant G5P[7] strain Group A rotavirus (RVA) is the most common diarrhea-causing pathogen among humans and animals worldwide. Rotavirus infection in neonatal calves causes major problems in the livestock industry. This study aimed to determine the prevalence and genetic diversity of bovine rotavirus (BoRVA) infections in calves with diarrhea and to perform whole genome analysis of an unusual strain, designated as RVA/Calf-wt/KOR/KNU-GJ2/2020/ G5P[7], that was detected in a 2-day-old diarrheic calf. From 459 diarrheic calves aged 1-40 days, fecal samples were collected and BoRVA infections were screened using real-time RT-PCR targeting VP6 gene. BoRVA was detected in 195 (42.4%) samples and was most prevalent in calves aged 1-10 days (47.2%). No significant difference in the BoRVA infection rate was observed between calves born in herds that were (42.1%) and were not (42.6%) vaccinated against BoRVA. A binomial regression analysis revealed that calves aged 1-10 days (95% confidence intervals [CI]:1.18-24.34; P = 0.000) and 11-20 days (95% CI: 0.76-16.83, P = 0.000) had a 5.37 and 3.58-fold higher BoRVA prevalence in comparison to those aged 31-40 days, respectively. The RVA-positive samples were subsequently subjected to amplification of the VP7 and VP4 genes for determining G and P genotypes. Overall, 45 (23.1%, 45/195) and 63 (32.3, 63/195) sequences for VP7 and VP4 were obtained. In this study, four G and three P genotypes were identified. G6 (86.7%) was the most prevalent genotype, followed by G8 (8.9%), G10 (2.2%), and G5 (2.2%). P[5] (92.1%) was the most frequently detected, followed by P[11] (6.3%), and P[7] (1.6%). The G6P[5] (82.2%) is the most common combination found in Korean native calves with diarrhea, whereas G6P[11] (4.4%) and G10P[11] (2.2%) had relatively low prevalence. G8P[5] (8.9%) was identified for the first time in diarrheic calves in the KOR. The uncommon strain KNU-GJ2 exhibited a G5-P[7] I5-R1-C1-M2-A1-N1-T1-E1-H1 genotype constellation possessing a typical porcine RVA backbone, with the exception of the VP3 gene, which is derived from bovine. Phylogenetically, except for VP3, ten gene segments of KNU-GJ2 were closely related to porcine, porcine-like, and reassortant bovine strains. Interestingly, the VP3-M2 gene of KNU-GJ2 clustered with bovine-like strains as well as reassortant porcine and bovine strains. Comparison of the NSP4s within a species-specific region of amino acids 131-141 demonstrated that KNU-GJ2 belonged to genotype B with porcine RVAs; however, it differed from porcine RVAs by one to three amino acids. The present study is fundamental to understanding the epidemiology and genotypes of circulating RVAs throughout the KOR and underscoring the importance of continuous monitoring and molecular characterization of RVAs circulating within animal populations for future vaccine development.

Article Prevalence and genetic characterization of bovine coronavirus identified from diarrheic pre-weaned native Korean calves from 2019 to 2021 Bovine coronavirus (BCoV) is associated with severe diarrhea in calves, winter dysentery in adult cattle, and respiratory diseases in cattle. However, there is currently limited information regarding its molecular characterization in the Republic of Korea (KOR). Therefore, this study investigated the prevalence of BCoV in diarrheic pre-weaned calves (aged <= 60 days) and compared BCoV genome sequences identified globally. A total of 846 fecal samples were collected from calves with diarrhea across 100 beef farms in the KOR. The samples were divided into three groups based on age as follows: 1-10 days (n = 490), 11-30 days (n = 277), and 31-60 days (n = 79). BCoV infection was detected in 50 calves by real-time RT-PCR analysis. The results showed that the prevalence of BCoV was associated with calf age (P = 0.028) and was significantly higher in calves aged 31-60 days (odds ratio: 2.69, 95% confidence interval: 1.24-5.85; P = 0.012) than in those aged 1-10 days. Our findings show that BCoV is an important etiological agent of diarrhea in calves aged 31-60 days. Fifteen full genome sequences (2019-2021 variants) of the spike, hemagglutinin/esterase, and nucleocapsid were obtained from the 50 BCoV-positive samples. Phylogenetic analysis of each gene revealed that BCoVs circulating worldwide might have no boundary between enteric and respiratory tropisms, demonstrating the presence of three BCoVs groups: the classical, Asia/USA, and European. Initially, Korean BCoVs were originated from the USA, but diverged since the 1980s and rapidly evolved independently, unlike in other Asian countries. In this study, Korean BCoVs are more recent BCoVs and present relatively high nucleotide substitution rates in all genes compared with other BCoVs. Our results showed that the 2019-2021 variants undergo continuous genetic evolution and that there are genetic differences among globally distributed BCoVs.

Article Role of wild birds in the spread of Glade 2.3.4.4e H5N6 highly pathogenic avian influenza virus into South Korea and Japan H5Nx highly pathogenic avian influenza viruses (HPAIVs) have caused transboundary epizootics in poultry and wild birds. In 2016, the H5N6 subtype of Glade 2.3.4.4e HPAIVs caused multiple outbreaks in Asia, including China, Japan, Korea, and Vietnam. However, the geographical spread pattern of 2.3.4.4e H5N6 HPAIV has not been clearly identified. To better understand the emergence and transmission history of 2.3.4.4e H5N6 HPAIV, we investigated the underlying epidemiologic processes associated with this viral spread by performing a Bayesian phylogeography analysis. The results revealed that wild waterfowl played a central role in the transboundary spread of Glade 2.3.4.4e H5N6 HPAIV into both endemic and non-endemic countries, causing multiple incursions of the 2.3.4.4e H5N6 HPAIV into South Korea, Japan, and Vietnam. In our analysis, Guangdong province, China was estimated to be the most probable site where 2.3.4.4e H5N6 HPAIVs emerged prior to the transboundary transmissions. Continued genomic surveillance in both wild birds and poultry would be necessary for monitoring of HPAIV incursions. In addition, enhanced biosecurity would be key to preventing the HPAIV spread by minimizing contact between domestic poultry and wild birds.

Article Enhancing adhesion of thermosetting urea-formaldehyde resins by preventing the formation of H-bonds with multi-reactive melamine Contemporary urea-formaldehyde (UF) resins with low-molar-ratio contain highly crystalline domains induced by the hydrogen (H) bonds between their linear molecules, which inhibits cross-linking, and results in poor adhesion. In this study, a novel way of controlling the crystallinity of such resins by preventing the formation of H-bonds using multi-reactive melamine during synthesis was reported. FTIR and(1)H-NMR spectroscopy confirmed the shifting of the carbonyl (C = O) peak, and N-H signal. XRD patterns revealed the conversion of crystalline to amorphous domains by adding 20% melamine, resulting in a decrease in crystallinity from 52 to 22%. The amorphous UF resins cured faster, have higher molecular weight and cross-linking density, and also followed the autocatalytic reaction model with excellent theoretical fitting. In addition, a 33% increase in adhesion strength, and a 62% reduction in formaldehyde emission was recorded. Hence, the addition of 20% melamine into the UF resins leads to better adhesion and less formaldehyde emission.

Article Isomeric yield ratio of ¹¹⁵m,gCd in the ¹¹⁶Cd(?,n) and 116Cd(n,2n) reactions The isomeric yield ratio (IR) of (115m,)gCd in the (116C)d(gamma,n) reaction at the bremsstrahlung endpoint energies of 70 and 75 MeV and in the (116Cd)(n,2n) reaction at the average neutron energies ( ) of 21.4 and 30.1 MeV were measured via an offline gamma -ray spectrometric technique. The bremsstrahlung energies were produced by impinging the electron beam energies of 70 and 75 MeV on a thin W-target at the Pohang Accelerator Laboratory, Korea. The neutron beams were obtained from the 9Be(p,n) reaction with the proton energies of 35 and 45 MeV using the MC-50 cyclotron at the Korean Institute of Radiological and Medical Sciences. The IR values at different bremsstrahlung and neutron energies were also calculated from the cross-section values of the TENDL-2019 li-brary based on the TALYS-1.9 code. The theoretical values agreed with the experimental data for the brems-strahlung endpoint energies but were slightly higher for all neutron energies. The current and literature data showed that in both the 116Cd(gamma,n) and 116Cd(n,2n) reactions, the IR value of 115m,gCd increases with the pro-jectile energy, indicating the role of excitation energy. However, the experimental and theoretical IR values at the same excitation energy were significantly higher for the 116Cd(n,2n) reaction than that for the 116Cd(gamma,n) reaction, highlighting the role of compound nucleus spin.

Article Measurement of the production cross-sections of ⁿatCd(p,x) reactions up to 45 MeV In this experimental study, we usednatCd as the target material and bombarded it with a 45-MeV energetic proton beam to study the natCd(p,x) reaction and determine the production cross-sections of In-109g,In-110g,In-111g,In-113m,In-114m,In-115m, Cd-107,Cd-109,Cd-115g, and Ag-105,Ag-106m,Ag-110m,Ag-111g radionuclides. The external beam line of the MC-50 cyclotron installed at Korea Institute of Radiological and Medical Sciences (South Korea) was used for the activation. We applied the well-known stacked-foil activation technique to measure the excitation functions of the reaction products. The active foils were analyzed using an offline gamma-ray spectrometry system to measure the production cross-sections. We also determined the thick target yield using the cross-section values. Subsequently, the measured results were compared with the theoretical model calculations using TALYS 1.9 code. In summary, the( nat)Cd(p,x) reaction is considerable because of its reaction products that have potential medical and industrial applications.

Article Morphological and Electrical Properties of Polythiophene Nanostructured Film Synthesized Using Atmospheric Pressure-Plasma Reactor with Double V-Shaped Bare Electrode To synthesize a wide-area conducting polymer with improved morphology and electrical properties, we proposed a new atmospheric pressure (AP) plasma reactor with double V-shaped bare wire electrode operating at a low driven voltage to expand the plasma area for nanostructure synthesis. The two wires form a V-shape making a 60 degrees angle at the edges and are joined together forming a cross, creating a canopy-like plasma medium in the plasma reactor center. Using the AP-plasma reactor, the polythiophene (PTh) nanostructured films are successfully synthesized with and without iodine doping. Moreover, the molecular structures and chemical properties of nascent and iodine-doped PTh films are compared, and the electrical resistivities of ex situ and in situ iodine-doped PTh nanostructures are also analyzed.

Article Photoresist Removal Using Reactive Oxygen Species Produced by an Atmospheric Pressure Plasma Reactor An atmospheric pressure (AP) plasma reactor driven by kHz sinusoidal power is developed to investigate effective removal of the photoresist (PR). This reactor can generate oxygen (O) and hydroxyl (OH) radicals simultaneously by introducing small quantities of oxygen (O-2) gas and hydrogen peroxide (H2O2) vapor along with the discharge gas. To investigate the effects of O and OH radicals on AP-plasma etching, Helium/O-2, helium/O-2/H2O2, argon/O-2 and argon/O-2/H2O2 plasmas are generated and tested. The PR layer with a thickness of 1.6 mu m is completely removed within 20 s using AP helium/O-2 plasma, and the PR is confirmed to chemically disappear by Fourier transform infrared (FT-IR) measurement. In this case, the etch rate is calculated as several tens of nm/s. When AP argon/O-2 plasma is used, the PR etch rate is lowered to several nm/s, and long-duration plasma treatment for PR removal damaged the silicon substrate without complete PR removal.

Article Chemical-bath-deposited rutile TiO2 film for electrochemical detection of 2,4,6-trinitrotoluene In this study, 2,4,6-trinitrotoluene (2,4,6-TNT) was detected electrochemically through cyclic voltammetry (CV) and differential pulse voltammetry (DPV) by using a rutile TiO2 layer under ambient conditions. To accomplish this, an electrode was fabricated in a short time by using the chemical bath deposition process under low temperature conditions. A rutile TiO2 layer was grown on both fluorine-doped tin oxide and glass surfaces by using a precursor solution containing chloride ions. Following calcination, the crystallinity of the rutile phases in the TiO2 layer was enhanced. In the CV profiles (obtained over a potential range between-0.6 and-1.2 V (versus Ag/AgCl, 3 M KCl) in a 100 ppm 2,4,6-TNT solution under ambient conditions), the three main reduction peaks of 2,4,6-TNT were observed only for the calcined TiO2 layer owing to the increased crystallinity of the rutile phase and the increased active site density. Calcination facilitated high active site density, a large electrochemically active surface area, and short electrochemical reaction times under low charge transfer resistance, which were key for enhancing the performance of the rutile TiO2 layer as the electrode toward 2,4,6-TNT detection. The DPV results revealed that the limits of detection and quantitation were 10.8 ppm and 36.0 ppm, respectively, with a linear range of 10-100 ppm, for 2,4,6-TNT detection using the calcined TiO2 layer as the working electrode. The detection of 2,4,6-TNT using a crystallized transition metal without a noble metal support is an attractive approach that can be applied toward the detection of other explosive nitro-organic compounds such as nitroglycerin and pentaerythritol tetranitrate.

Article Magnetic domain structure of the ferrimagnetic (001) NiCo2O4 film with perpendicular magnetic anisotropy A 65-nm thick epitaxial (001) NiCo2O4 film that has metallic and ferrimagnetic properties at room temperature was grown on a (001) MgAl2O4 substrate. Evolutions in magnetic domains of the ferrimagnetic (001) NiCo2O4 film with perpendicular magnetic anisotropy were observed using polar magneto-optical Kerr effect microscopy with changes in magnetic field, temperature, or time. The magnetic domain structure in the magnetic field exhibited noticeable changes around a coercive field; whereas, its change in temperature or time at a fixed magnetic field was indistinct. This suggests that the ferrimagnetic (001) NiCo2O4 film has a relatively stable magnetic domain structure in comparison with Co alloy films with perpendicular magnetic anisotropy and fast domain wall motion. Conclusively, the magnetic domain variation in the NiCo2O4 film signified that the magnetization process at an early stage was mainly caused by domain rotation behavior rather than domain wall motion.

Article Analytical Structure and Performance of Interval Type-2 Fuzzy Two-Term Controllers with Varying Footprint of Uncertainty While type-2 fuzzy control has gained a lot of attention in the recent years, several challenges still remain with respect to controller design. The footprint of uncertainty (FoU) plays a very important role in designing type-2 fuzzy controllers, since the performance of type-2 fuzzy controllers largely depends on the choice of FoU. In this paper, we propose a simplified model of interval type-2 (IT2) fuzzy two-term controllers of Takagi-Sugeno (TS) type with only two rules in the rule base. The controller model is derived with varying FoUs based on only two type-2 input fuzzy sets (the simplest case). An extension to multiple input fuzzy sets is also presented. We investigate the variation in control surface and computational aspects of the IT2 fuzzy two-term controller as the FoU is varied. The performance of the proposed IT2 fuzzy controller with respect to varying FoUs is evaluated in the simulation study.

Article Artemisiae argyi Water Extract Alleviates Obesity-Induced Metabolic Disorder Artemisiae argyi is a well-known traditional herbal medicine used in East Asia. Although the antibacterial and anti-inflammatory effects of A. argyi have been reported, its efficacy in improving obesity has not been yet evaluated. In this study, mice were fed a normal diet (AIN-93), a high-fat diet (HFD, 60% of kcal from fat), and an HFD with 0.1% of A. argyi water extract for 16 weeks. The body weight and body fat in A. argyi-fed mice significantly decreased via upregulation of the mRNA expression of fatty acid oxidation-related genes, with a simultaneous decrease in plasma lipid content and leptin levels. A. argyi water extract also ameliorated hepatic steatosis by restricting lipogenesis via lowering the activities of fatty acid synthase and phosphatidic acid phosphatase. Consistently, hepatic histological analysis indicated that A. argyi water extract decreased hepatic lipid accumulation in accordance with the hepatic H, E and Oil Red O-stained area. Additionally, A. argyi ameliorated the impaired glucose homeostasis by increasing the mRNA expression of AMP-activated kinase and glycolysis-related genes. In conclusion, our results indicate that A. argyi can be used to treat obesity-related metabolic conditions.

Article Fermionic construction in the supersymmetric coset model It is known previously that the operator product expansion (OPE) between the first N = 3 multiplet and itself contains the second N = 3 multiplet in the supersymmetric coset model. In this paper, by using their realizations in terms of various fermions, we compute the four kinds of OPEs between the first and the second N = 3 multiplets for fixed N andM, where the group of the coset contains SU(N+M). By supersymmetrizing the above OPEs in N = 3 superspace and using the various Jacobi identities between the currents, we determine the N = 3 supersymmetric OPE between the first and the second N = 3 multiplets completely. The right-hand side of this OPE contains the various N = 3 multiplets: the SO(3) singlet N = 3 multiplets of superspin- 3 2; 2; 3; 4 and the SO(3) triplet N = 3 multiplets of superspin-5/2; 3; 7/2. The N = 2 superspace description and the decoupling of the spin-1/2 current of the N = 3 superconformal algebra are also described.

Article Immune Pathway and Gene Database (IMPAGT) Revealed the Immune Dysregulation Dynamics and Overactivation of the PI3K/Akt Pathway in Tumor Buddings of Cervical Cancer Tumor budding (TB) is a small cluster of malignant cells at the invasive front of a tumor. Despite being an adverse prognosis marker, little research has been conducted on the tumor immune microenvironment of tumor buddings, especially in cervical cancer. Therefore, RNA sequencing was performed using 21 formalin-fixed, paraffin-embedded slides of cervical tissues, and differentially expressed genes (DEGs) were analyzed. Immune Pathway and Gene Database (IMPAGT) was generated for immune profiling. "Pathway in Cancer" was identified as the most enriched pathway for both up- and downregulated DEGs. Kyoto Encyclopedia of Genes and Genomes Mapper and Gene Ontology further revealed the activation of the PI3K/Akt signaling pathway. An IMPAGT analysis revealed immune dysregulation even at the tumor budding stage, especially in the PI3K/Akt/mTOR axis, with a high efficiency and integrity. These findings emphasized the clinical significance of tumor buddings and the necessity of blocking the overactivation of the PI3K/Akt/mTOR pathway to improve targeted therapy in cervical cancer.

Article Induction of Apoptosis and Effect on the FAK/AKT/mTOR Signal Pathway by Evodiamine in Gastric Cancer Cells Evodiamine isolated from Evodia rutaecarpa has been known to have anti-tumor activity against various cancer cell types. Although there have been reports showing the inhibitory effect of evodiamine on cell survival of gastric cancer cell, it is not clearly explained how evodiamine affects the expression and modification of proteins associated with apoptosis and upstream signal pathways. We confirmed the cytotoxic activity of evodiamine against AGS and MKN45 cells by a WST assay, cell morphological change, and clonogenic assay. The apoptotic cells were evaluated by Annexin V/PI analysis and Western blot and the expressions of apoptosis-related molecules were confirmed by Western blot. Evodiamine promoted apoptosis of AGS gastric cancer cells through both intrinsic and extrinsic signal pathways in a time- and dose-dependent manner. Evodiamine attenuated the expression of anti-apoptotic proteins, including Bcl-2, XIAP, and survivin, and elevated that of the pro-apoptotic protein Bax. Evodiamine also suppressed the FAK/AKT/mTOR signal pathway. Based on these results, we expect that the results from this study will further elucidate our understanding of evodiamine as an anti-cancer drug.
