| ○ | ○ | Article | On m-complex symmetric weighted shift operators on Cⁿ | In this paper we study m-complex symmetric weighted shift operators on C-n. Let T be the (backward) weighted shift on C-n for some n >= 2. We consider when T and T-a (the matrix of entries the moduli of those of T) are both m-complex symmetric with the (same) standard conjugation C, give as well some unitary operators useful in the study, and generalize to upper triangular matrices. Also, we show that if T is 2k-complex symmetric with the standard conjugation C for some k is an element of N with k < n, then T is (2k - 1)-complex symmetric with the conjugation C.

| ○ | ○ | Article | Quick-start guide for first-principles modelling of point defects in crystalline materials | Defects influence the properties and functionality of all crystalline materials. For instance, point defects participate in electronic (e.g. carrier generation and recombination) and optical (e.g. absorption and emission) processes critical to solar energy conversion. Solid-state diffusion, mediated by the transport of charged defects, is used for electrochemical energy storage. First-principles calculations of defects based on density functional theory have been widely used to complement, and even validate, experimental observations. In this 'quick-start guide', we discuss the best practice in how to calculate the formation energy of point defects in crystalline materials and analysis techniques appropriate to probe changes in structure and properties relevant across energy technologies. | Kim, Sunghyun; Hood, Samantha N.; Park, Ji-Sang; Whalley, Lucy D.; Walsh, Aron | Imperial Coll London, Dept Mat, Exhibition Rd, London SW7 2AZ, England; Yonsei Univ, Dept Mat Sci & Engn, Seoul 03722, South Korea; Kyungpook Natl Univ, Dept Phys, Daegu 41566, Daegu 41566, South Korea | Walsh, Aron/A-7843-2008; Park, Ji-Sang/F-9944-2010 | 55719000400; 57192087597; 36671796300; 57192416581; 35315151400 | a.walsh@imperial.ac.uk; | JOURNAL OF PHYSICS-ENERGY | J PHYS-ENERGY | 2515-7655 | 2 | 3 | SCIE | ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2020 | 5.967 | 26.2 | 1.77 | 2025-06-25 | 36 | 36 | point defect; carrier trapping; ion transport; materials modelling; density functional theory | ENERGY | Carrier trapping; Density functional theory; Ion transport; Materials modelling; Point defect | Calculations; Charge carriers; Crystallites; Density functional theory; Diffusion in solids; Energy conversion; Energy storage; Nanocrystalline materials; Solar energy; Absorption and emissions; Analysis techniques; Electrochemical energy storage; Energy technologies; First-principles calculation; Formation energies; Solid-state diffusion; Structure and properties; Point defects | English | 2020 | 2020-07 | 10.1088/2515-7655/aba081 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Softening of lotus root and carrot using freeze-thaw enzyme infusion for texture-modified foods | Freeze-thaw enzyme infusion was used to soften lotus root and carrot, and to develop texture-modified foods. Samples were dipped into 0.25% cellulase solution with different vacuum pressures (0-0.05 MPa), vacuum times (5-30 min), and restoration times (0-120 min). Effects of these treatments on maximum force and pH were determined. Overall, the maximum force and pH of samples decreased as vacuum pressure, and vacuum and restoration times increased. The texture softening rate (K) and residual texture (d) were obtained from a firstorder model, and results showed that the K value of the lotus root increased as vacuum time increased. K and d values for the carrot decreased as vacuum time increased. A regression analysis confirmed that lotus root texture was strongly influenced by restoration time, while carrot texture was more affected by vacuum time. Overall, color values were lower for untreated samples compared to treated sample. Compared with cooked samples, samples cooked after freeze-thaw enzyme infusion with restoration showed a significantly reduced maximum force by 84% for lotus root and 58% for carrot. These data suggested that treatment with freeze-thaw enzyme infusion followed by restoration before cooking helps soften lotus root and carrot tissue. | Park, Jong Jin; Lee, Won Young | Kyungpook Natl Univ, Sch Food Sci & Technol, Daegu 41566, South Korea | Park, Jongjin/AAL-3484-2021; Lee, Wonyoung/AAL-2780-2021 | 58602432200; 57195940408 | bjj1490@nate.com;wonyoung@knu.ac.kr; | FOOD BIOSCIENCE | FOOD BIOSCI | 2212-4292 | 2212-4306 | 35 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2020 | 4.24 | 26.2 | 0.59 | 2025-06-25 | 13 | 14 | Cellulase; Daucus carota; Freeze-thawed enzyme infusion; Nelumbo nucifera root; Softening vegetable; Texture-modified food | VACUUM IMPREGNATION; PHYSICOCHEMICAL PROPERTIES; OSMOTIC DEHYDRATION; VEGETABLES; FRUITS; PRETREATMENTS; REDUCTION; PRESSURE; COOKING; IMPROVE | Cellulase; Daucus carota; Freeze-thawed enzyme infusion; Nelumbo nucifera root; Softening vegetable; Texture-modified food | English | 2020 | 2020-06 | 10.1016/j.fbio.2020.100557 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Statistical ensemble inequivalence for flexible polymers under confinement in various geometries | The problem of statistical ensemble inequivalence for single polymers has been the subject of intense research. In a recent publication, we show that even though the force-extension relation of a free Gaussian chain exhibits ensemble equivalence, confinement to half-space due to tethering to a planar substrate induces significant inequivalence [S. Dutta and P. Benetatos, Soft Matter, 2018, 14, 6857-6866]. In the present article, we extend that work to the conformational response to confining forces distributed over surfaces. We analyze in both the Helmholtz and the Gibbs ensemble the pressure-volume equation of state of a chain in rectangular, spherical, and cylindrical confinement. We especially consider the case of a directed polymer in a cylinder. We also analyze the case of a tethered chain inside a rectangular box, a sphere, and outside a sphere. In general, confinement causes significant ensemble inequivalence. Remarkably, we recover ensemble equivalence in the limit of squashing confinement. We trace the ensemble inequivalence to the persistence of strong fluctuations. Our work may be useful in the interpretation of single molecule experiments and caging phenomena. | Dutta, Sandipan; Benetatos, Panayotis | Inst Basic Sci, Ctr Soft & Living Matter, Ulsan 44919, South Korea; Kyungpook Natl Univ, Dept Phys, 80 Daehakro, Daegu 41566, South Korea | Benetatos, Panayotis/AAT-5957-2021 | 56844405300; 6507575810 | pben@knu.ac.kr; | SOFT MATTER | SOFT MATTER | 1744-683X | 1744-6848 | 16 | 8 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, MULTIDISCIPLINARY;POLYMER SCIENCE | 2020 | 3.679 | 26.2 | 0.56 | 2025-06-25 | 13 | 13 | COMPRESSION; EQUIVALENCE; EXTENSION; BRUSHES; MODEL | Equations of state; Spheres; Conformational response; Ensemble inequivalence; Flexible polymers; Force-extension relations; Planar substrate; Pressure-volume equation of state; Single molecule experiments; Statistical ensembles; Polymers | English | 2020 | 2020-02-28 | 10.1039/c9sm02246e | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | CYTOPROTECTIVE EFFECTS OF FERMENTED OYSTER EXTRACTS AGAINST OXIDATIVE STRESS-INDUCED DNA DAMAGE AND APOPTOSIS THROUGH ACTIVATION OF THE NRF2/HO-1 SIGNALING PATHWAY IN MC3T3-E1 OSTEOBLASTS | Osteoblast damage by oxidative stress has been recognized as a cause of bone-related disease, including osteoporosis. Recently, we reported that fermented Pacific oyster (Crassostrea gigas) extracts (FO) inhibited osteoclastogenesis and osteoporosis, while promoting osteogenesis. However, since the beneficial potential of FO on osteoblasts is not well known, in the present study, we investigated the cytoprotective effect of FO against oxidative stress in MC3T3-E1 osteoblasts. Our results demonstrated that FO inhibited hydrogen peroxide (H2O2)-induced DNA damage and cytotoxicity through the rescue of mitochondrial function by blocking abnormal ROS accumulation. FO also prevented apoptosis by suppressing loss of mitochondrial membrane potential and cytosolic release of cytochrome c, decreasing the rate of Bax/Bcl-2 expression and reducing the activity of caspase-9 and caspase3 in H2O2-stimulated MC3T3-E1 osteoblasts, suggesting that FO protected MC3T3-E1 osteoblasts from the induction of caspase dependent- and mitochondria-mediated apoptosis by oxidative stress. In addition, FO markedly promoted the activation of nuclear factor-erythroid-2-related factor 2 (Nrf2), which was associated with the enhanced expression of heme oxygenase-1 (HO-1). However, inhibiting the expression of HO-1 by artificially blocking the expression of Nrf2 using siRNA significantly eliminated the protective effect of FO, indicating that FO activates the Nrf2/HO-1 signaling pathway in MC3T3-E1 osteoblasts to protect against oxidative stress. Based on the present data, FO is thought to be useful as a potential therapeutic agent for the inhibition of oxidative stress in osteoblasts. | Park, Cheol; Lee, Hyesook; Han, Min Ho; Jeong, Jin-Woo; Kim, Sung Ok; Jeong, Soon-Jeong; Lee, Bae-Jin; Kim, Gi-Young; Park, Eui Kyun; Jeon, You-Jin; Choi, Yung Hyun | Dong Eui Univ, Div Basic Sci, Coll Liberal Studies, Busan, South Korea; Dong Eui Univ, Antiaging Res Ctr, Busan, South Korea; Dong Eui Univ, Dept Biochem, Coll Korean Med, 52-57 Yangj Eong Ro, Busan 47227, South Korea; Natl Marine Biodivers Inst Korea, Seocheon, South Korea; Nakdonggang Natl Inst Biol Resources, Freshwater Bioresources Utilizat Bur, Sangju, South Korea; Kyungsung Univ, Coll Engn, Dept Food Sci & Biotechnol, Busan, South Korea; Youngsan Univ, Coll Hlth Sci, Dept Dent Hyg, Yangsan, South Korea; Marine Bioproc Co Ltd, Ocean Fisheries & Biol Ctr, Busan, South Korea; Jeju Natl Univ, Dept Marine Life Sci, Jeju, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral Pathol & Regenerat Med, Daegu, South Korea | ; Kim, Kyoung-Sook/A-7768-2017; Jeon, You-Jin/AAD-3452-2021; 정, 순정/GVU-3261-2022 | 7408418079; 57192499270; 58594848400; 55199557300; 34770981600; 46761269800; 35620558000; 7403063801; 37071072400; 55782690600; 57211727369 | choiyh@deu.ac.kr; | EXCLI JOURNAL | EXCLI J | 1611-2156 | 19 | SCIE | BIOLOGY | 2020 | 4.068 | 26.3 | 1.01 | 2025-06-25 | 16 | 17 | Fermented oyster extract; ROS; DNA damage; apoptosis; Nrf2/HO-1 | DEXAMETHASONE-INDUCED APOPTOSIS; CULTURED HUMAN HEPATOCYTES; PHENOLIC ANTIOXIDANT; MEDIATED APOPTOSIS; CRASSOSTREA-GIGAS; ACID PROMOTES; COMET ASSAY; BONE LOSS; PROTECTS; CELLS | Apoptosis; DNA damage; Fermented oyster extract; Nrf2/HO-1; ROS | caspase 3; caspase 9; heme oxygenase 1; hydrogen peroxide; oyster extract; reactive oxygen metabolite; small interfering RNA; transcription factor Nrf2; animal cell; apoptosis; Article; bioaccumulation; cell culture; cell protection; cell viability; chemoluminescence; colorimetry; comet assay; controlled study; cytotoxicity; DNA damage; enzyme activation; in vitro study; MC3T3-E1 cell line; mitochondrial membrane potential; mitochondrion; mouse; MTT assay; nonhuman; oxidative stress; protein expression; protein RNA binding; signal transduction; Western blotting | English | 2020 | 2020 | 10.17179/excli2020-2376 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of temperature on single- and mixed-strain fermentation of ruminant feeds | Use of raw feedstuffs for livestock is limited by low digestibility. Recently, fermentation of feedstuffs has been highlighted as a new way to improve nutrient absorption through the production of organic acids using inoculated microorganisms, which can also play a probiotic role. However, standard procedures for feedstuff fermentation have not been clearly defined because the process is influenced by climatic variation, and an analytical standard for fermented feedstuffs is lacking. This study aimed to evaluate the microbiological and biochemical changes of feedstuffs during fermentation at temperatures corresponding to different seasons (10 degrees C, 20 degrees C, 30 degrees C, and 40 degrees C). We also investigated the effects of yeast, lactic acid bacteria (LAB), and Bacillus spp. on fermentation and determined the results of their interactions during fermentation. The viable cells were observed within 8 days in single-strain fermentation. However, when feedstuffs were inoculated with a culture of mixed strains, LAB were predominant at low temperatures (10 degrees C and 20 degrees C), while Bacillus spp. was predominant at high temperatures (30 degrees C and 40 degrees C). A significant drop in pH from 6.5 to 4.3 was observed when LAB was the dominant strain in the culture, which correlated with the concentrations of lactic acid. Slight ethanol production was detected above 20 degrees C regardless of the incubation temperature, suggesting active metabolism of yeast, despite this organism making up a marginal portion of the microbes in the mixed culture. These results suggested that fermentation temperature significantly affects microbiological profiles and biochemical parameters, such as pH and the lactic acid concentration, of fermented feedstuffs. Our data provide valuable information for the determination of industrial standards for fermented feedstuffs. | Woo, Seungmin; Kim, Sooah; Ye, Suji; Kim, Soo Rin; Seol, Jeongman; Dooyum, Uyeh Daniel; Kim, Junhee; Hong, Dong Hyuck; Kim, Jong Nam; Ha, Yushin | Kyungpook Natl Univ, Dept Bio Ind Machinery Engn, Daegu 41566, South Korea; Jeonju Univ, Dept Environm Sci & Biotechnol, Jeonju 55069, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Dongseo Univ, Dept Food Sci & Nutr, Busan 47011, South Korea | ; Kim, Soo Rin/X-2192-2019 | 57192074884; 36554561100; 57208240237; 36659584200; 57191336541; 57192916175; 57197854979; 57192068978; 57201935201; 57192072314 | yorker20@gdsu.dongseo.ac.kr;yushin72@knu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 62 | 2 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2020 | 2.225 | 26.4 | 0.24 | 2025-06-25 | 5 | 3 | Agricultural by-products; Fermented feeds; Saccharomyces cerevisiae; Bacillus subtilis; Lactobacillus plantarum | LACTIC-ACID BACTERIA; SACCHAROMYCES-CEREVISIAE; AEROBIC STABILITY; LACTOBACILLUS-BUCHNERI; SILAGE FERMENTATION; NUTRITIVE-VALUE; SOYBEAN-MEAL; DAIRY-COWS; BY-PRODUCT; RUMEN | Agricultural by-products; Bacillus subtilis; Fermented feeds; Lactobacillus plantarum; Saccharomyces cerevisiae | English | 2020 | 2020 | 10.5187/jast.2020.62.2.227 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effects of supplementing limiting amino acids on milk production in dairy cows consuming a corn grain and soybean meal-based diet | Limiting amino acids (AAs) for milk production in dairy cows fed on a concentrate diet of corn grain and soybean meal was evaluated in this study. Four lactating and multiparous Holstein cows (in third or fourth parities, with an average body weight of 633 +/- 49.2 kg), 8 to 9 weeks into their lactation period, were used in a 4 x 4 Latin square design. The experiment comprised four dietary treatments: (1) no intravenous infusion (control); (2) control plus intravenous infusion of an AA mixture of 6 g/d methionine, 19.1 g/d lysine, 13.8 g/d isoleucine, and 15.4 g/d valine (4AA); (3) control plus intravenous infusion of the AA mixture without methionine (no-Met); and (4) control plus intravenous infusion of the AA mixture without lysine (no-Lys). All animals were fed on a controlled diet (1 kg/d alfalfa hay, 10 kg/d silage, 14 kg/d concentrate mixture, ad libitum timothy hay). The AA composition of the diet and blood were determined using an automatic AA analyzer. Milk composition (protein, fat, lactose, urea nitrogen, and somatic cell counts) was determined using a MilkoScan. The results showed that feed intake for milk production did not differ from that of intravenous infusion using a limiting AA mixture. The 4AA treatment numerically had the highest milk yield (32.4 kg/d), although there was no difference when compared with the control (31.2 kg/d), no-Met (31.3 kg/d), and no-Lys (31.7 kg/d) treatments. The concentration of AAs in blood plasma of cows in all treatments, mainly isoleucine and valine, increased significantly compared with that of control. The no-Met treatment increased (p < 0.05) the concentration of lysine in the blood relative to the control and no-Lys treatments, whereas the no-Lys treatment increased (p < 0.05) the concentration of methionine relative to the control and no-Met treatments. In conclusion, milk production increased when feeding 10 g/d methionine to the cows, together with their concentrate diet of corn grain and soybean meal. | Park, Joong Kook; Yeo, Joon-Mo; Bae, Gui-Seck; Kim, Eun Joong; Kim, Chang-Hyun | Hankyong Natl Univ, Sch Anim Life Convergence Sci, Anseong 17579, South Korea; Korean Natl Coll Apiculture & Fisheries, Dept Dairy Sci, Jeonju 54874, South Korea; Chung Ang Univ, Dept Anim Sci & Technol, Anseong 17546, South Korea; Kyungpook Natl Univ, Dept Anim Sci, Sangju 37224, South Korea | Kim, Eun Joong/HGF-1639-2022; Park, Ji/ABG-5893-2020; Bae, Gui-Seck/W-7902-2019 | 57208164337; 14065489900; 8207886400; 57213620881; 55618227500 | kimch@hknu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 62 | 4 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2020 | 2.225 | 26.4 | 1.3 | 2025-06-25 | 13 | 14 | Limiting amino acid; Methionine; Lysine; Dairy cow | RUMEN-PROTECTED METHIONINE; ABOMASAL INFUSIONS; GRASS-SILAGE; NITROGEN-UTILIZATION; LACTATING COWS; DL-METHIONINE; PROTEIN; LYSINE; PERFORMANCE; HISTIDINE | Dairy cow; Limiting amino acid; Lysine; Methionine | English | 2020 | 2020 | 10.5187/jast.2020.62.4.485 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Evaluation of energy and amino acids of brown rice and its effects on laying performance and egg quality of layers | Two experiments were conducted to determine apparent metabolizable energy (AME), nitrogen-corrected AME (AMEn), and ileal digestible amino acid (AA) content of brown rice (BR) and to investigate the effect of dietary supplementation of BR on laying performance and egg quality of laying hens. In Exp. 1, 72 Hy-line Brown layers (49-week-old) were allocated to two treatments using a completely randomized block design, and each treatment included six cages per treatment and six hens per cage. A semi-purified diet was formulated to include BR as the sole source of AA and energy and an N-free diet was used to determine basal endogenous loss of AA. The hens were fed a commercial layer diet for adaptation to the experimental environment and diet for 7 days from d 0, and then fed experimental diets for 5 days from d 7. Excreta were collected from d 10 to 11 and ileal digesta were collected on d 12. On a dry matter (DM) basis, the AME and AMEn of BR was determined at 3,773 and 3,729 kcal/kg, respectively. The apparent ileal digestibility (AID) of BR ranged from 32.7% for Thr to 73.7% for Arg. The range of the standardized ileal digestibility (SID) value was between 79.4% for Met and 96.6% for Lys. In Exp. 2, 252 Hy-line Brown layers (44-week-old) were divided into four groups, comprising seven replicates of nine birds each and assigned to four experimental diets containing 0 (Control), 5%, 10%, or 15% BR for 5 weeks. The BR-containing diets were formulated to be equal in the content of AMEn and digestible AA to those of the diet without BR. No significant differences were observed in laying performances. Egg quality and blood profiles were not linearly or quadratically affected by dietary treatments. These results suggest that up to 15% BR can be included into layer feed without any adverse effects on laying performance and egg quality, if its energy and digestible AA values are well evaluated. | An, Byoung-Ki; An, Su Hyun; Jeong, Han-Seul; Kim, Kwan-Eung; Kim, Eun Jip; Lee, Sang-Rak; Kong, Changsu | Konkuk Univ, Dept Anim Sci & Technol, Seoul 05029, South Korea; Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea; Nonghyup Feed, R&D Ctr, Seoul 05398, South Korea; Yonam Coll, Div Anim Husb, Cheonan 31005, South Korea; Kyungpook Natl Univ, Dept Anim Sci, Sangju 37224, South Korea | 안, 수현/JFK-5079-2023 | 7007154139; 57216974969; 57217630013; 57209988434; 56389998000; 37056875600; 36027521600 | changsukong@knu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 62 | 3 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2020 | 2.225 | 26.4 | 0.12 | 2025-06-25 | 3 | 4 | Brown rice; Apparent metabolizable energy; Standardized ileal digestible amino acids; Egg production; Laying hens | DISTILLERS DRIED GRAINS; DIETARY CALCIUM LEVELS; GROWTH-PERFORMANCE; BROILERS; CORN; DIGESTIBILITY; FEEDSTUFF; SOLUBLES; NITROGEN; LOSSES | Apparent metabolizable energy; Brown rice; Egg production; Laying hens; Standardized ileal digestible amino acids | English | 2020 | 2020 | 10.5187/jast.2020.62.3.374 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Exploring the feasibility of Salmonella Typhimurium-specific phage as a novel bio-receptor | The purpose of this study was aimed to isolate a Salmonella Typhimurium-specific phage (KFS-ST) from washing water in a poultry processing facility and to investigate the feasibility of the KFS-ST as a novel bio-receptor for the magnetoelastic (ME) biosensor method. KFSST against S. Typhimurium was isolated, propagated, and purified using a CsCl-gradient ultracentrifugation. Morphological characteristics of KFS-ST were analyzed using transmission electron microscopy (TEM). Its specificity and efficiency of plating analysis were conducted against 39 foodborne pathogens. The temperature and pH stabilities of KFS-ST were investigated by the exposure of the phage to various temperatures (-70 degrees C-70 degrees C) and pHs (1-12) for 1 h. A one-step growth curve analysis was performed to determine the eclipse time, latent time and burst size of phage. The storage stability of KFS-ST was studied by exposing KFSST to various storage temperatures (-70 degrees C, -20 degrees C, 4 degrees C, and 22 degrees C) for 12 weeks. KFS-ST was isolated and purified with a high concentration of (11.47 +/- 0.25) Log PFU/mL. It had an icosahedral head (56.91 +/- 2.90 nm) and a non-contractile tail (225.49 +/- 2.67 nm), which was classified into the family of Siphoviridae in the order of Caudovirales. KFS-ST exhibited an excellent specificity against only S. Typhimurium and S. Enteritidis, which are considered two of the most problematic Salmonella strains in the meat and poultry. However, KFS-ST did not exhibit any specificity against six other Salmonella and 27 non-Salmonella strains. KFS-ST was stable at temperature of 4 degrees C to 50 degrees C and at pH of 4 to 12. The eclipse time, latent time, and burst size of KFS-ST were determined to be 10 min, 25 min and 26 PFU/ infected cell, respectively. KFS-ST was relatively stable during the 12-week storage period at all tested temperatures. Therefore, this study demonstrated the feasibility of KFS-ST as a novel bio-receptor for the detection of S.

| ○ | ○ | Article | N-acetylcysteine modulates cyclo-phosphamide-induced immunosuppression, liver injury, and oxidative stress in miniature pigs | Cyclophosphamide, a cytotoxic anticancer agent, induces immunosuppression and has several adverse effects. N-acetylcysteine alleviates oxidative stress, liver injury, and intestinal tissue damage. The present study examined whether N-acetylcysteine modulates the adverse effects of cyclophosphamide in pigs. Miniature pigs (n = 15) were used as an experimental model to evaluate the effects of N-acetylcysteine treatment on immune reactions, liver injury, and oxidative stress after cyclophosphamide challenge. Corn-soybean meal based dietary treatments were as follows: control diet with either saline injection, cyclophosphamide injection, or 0.5% N-acetylcysteine and cyclophosphamide injection. N-acetylcysteine increased the number of immune cells and decreased TNF-alpha production after cyclophosphamide injection and decreased TNF-alpha, IFN-gamma, NF-kappa B, and IL-8 expression and increased IL-10 expression in peripheral blood mononuclear cells. Serum levels of alanine transaminase and aspartate aminotransferase decreased, superoxide dismutase activity increased, and malondialdehyde activity decreased following N-acetylcysteine treatment after cyclophosphamide injection. N-acetylcysteine decreases immunosuppression, liver injury, and oxidative stress in cyclophosphamide-challenged miniature pigs. The present study suggests that N-acetylcysteine has therapeutic application in livestock for modulating immune reactions, liver injury, and oxidative stress. | Kang, Kyung Soo; Shin, Sangsu; Lee, Sang In | Ovozen Inc, Bio Div, Suwon 16636, South Korea; Kyungpook Natl Univ, Dept Anim Biotechnol, Sangju 37224, South Korea | 57198425395; 55490360000; 57203597336 | sss@knu.ac.kr;silee78@knu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 62 | 3 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2020 | 2.225 | 26.4 | 0.47 | 2025-06-25 | 9 | 8 | Cyclophosphamide; Miniature pig; N-acetylcysteine; Peripheral blood mononuclear cells | BLOOD MONONUCLEAR-CELLS; GENE-EXPRESSION; CYCLOPHOSPHAMIDE; METABOLISM; EXPANSION; MINIPIG; REDOX; TLR4 | Cyclophosphamide; Miniature pig; N-acetylcysteine; Peripheral blood mononuclear cells | English | 2020 | 2020 | 10.5187/jast.2020.62.3.348 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The effect of protease on growth performance, nutrient digestibility, and expression of growth-related genes and amino acid transporters in broilers | During the course of this trial, our team assessed the influence of protease upon the growth performance, the nutrient digestibility, and the expression of growth-related genes and amino acid transporters within the liver, muscle, and small intestines of broilers. During the first step, our team allocated 600 broilers into four dietary treatments for a period of 35 days in order to measure the growth performance and nutrient digestibility of the broilers selected. The separate treatments contained 10 replicates (15 birds per replicate). The treatments were composed of: 1) CON, basal diet; 2) T1, basal diet + 0.03% protease; 3) T2, basal diet + 0.06% protease; and 4) T3, basal diet + 0.09% protease. Next, the broiler chick sample tissue was harvested from the CON and T3 groups in order to conduct gene expression analysis following the feeding trials the broilers underwent. Our team discovered that the broilers fed protease diets possessed increased body weight and an average daily gain, but conversely, had lower feed conversion ratios when their dietary protease levels increased from 0% to 0.09% (p < 0.05). Additionally, significant linear improvements were identified among the nutrient digestibility of dry matter, crude protein, energy, and amino acids within broilers supplied with protease diets when contrasted and compared with broilers supplied with the basal diet (p < 0.05). In addition, the gene expression of the genes IGF1, IGF2, GH, and LEP in the liver, and the genes MYOD1 and MYOG in the breast muscles, was significantly increased after broilers were fed with a protease diet as compared to broilersthat subsisted on a basal diet (p < 0.05). Protease supplementation also raised the expression levels within these amino acid transporters: SCL6A19, SLC7A1, SLC7A7, SLC7A2, SLC7A6, SLC7A9, and SLC15A1, located in the small intestine, when compared to the basal diet (p < 0.05). Our results suggest that protease supplementation in their diet improved the growth performance of broilers via an increase in the expression growth-related genes within broiler liver and muscle tissue. In addition, protease supplementation enhanced broiler digestibility via the upregulation of amino acid transporter expression within the small intestine. | Park, Jae Hong; Lee, Sang In; Kim, In Ho | Dankook Univ, Dept Anim Resource & Sci, Cheonan 31116, South Korea; Kyungpook Natl Univ, Dept Anim Biotechnol, Sangju 37224, South Korea | 56988396000; 57203597336; 36050641300 | inhokim@dankook.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 62 | 5 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2020 | 2.225 | 26.4 | 0.94 | 2025-06-25 | 17 | 16 | Amino acids; Broiler; Protease; Small intestine; Transporter | SATELLITE CELL-PROLIFERATION; IGF-BINDING PROTEIN-1; CARCASS CHARACTERISTICS; EXOGENOUS PROTEASE; NUTRITIONAL-STATUS; INTESTINAL MORPHOLOGY; BLOOD-CONSTITUENTS; TRYPSIN ACTIVITY; MUSCLE GROWTH; IMPROVES | Amino acids; Broiler; Protease; Small intestine; Transporter | English | 2020 | 2020 | 10.5187/jast.2020.62.5.614 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | An optimized hepatocellular carcinoma prediction model for chronic hepatitis B with well-controlled viremia | Background and Aims Hepatocellular carcinoma (HCC) risk in chronic hepatitis B (CHB) substantially decreased in the era of potent antiviral therapy. We developed an optimized HCC risk prediction model for CHB with well-controlled viremia by nucelos(t)ide analogs (NUCs). Method We analysed those who achieved virological response (VR; serum HBV-DNA = 11 kPa (aHR 6.09) were independently associated with HCC. Using these, CAMPAS model was developed with c-index of 0.874. The predicted and observed HCC probabilities were calibrated with a reliable agreement. Such results were reproduced from internal validation and external validation among the independent cohort (n = 252). The intermediate-risk (CAMPAS model score 75 similar to 161) and high-risk (score >161) groups were more likely to develop HCC compared with the low-risk group (score <= 75) with statistical significances (HRs; 4.43 and 47.693 respectively; both P < .001). Conclusion CAMPAS model derived through comprehensive clinical evaluation of liver disease allowed the more delicate HCC prediction for CHB patients with well-controlled viremia by NUCs. | Lee, Hye W.; Park, Soo Y.; Lee, Myeongjee; Lee, Eun J.; Lee, Jinae; Kim, Seung U.; Park, Jun Y.; Kim, Do Y.; Ahn, Sang H.; Kim, Beom K. | Yonsei Univ, Dept Internal Med, Coll Med, 50-1 Yonsei Ro, Seoul 03722, South Korea; Yonsei Univ, Inst Gastroenterol, Coll Med, Seoul, South Korea; Severance Hosp, Yonsei Liver Ctr, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Daegu, South Korea; Yonsei Univ, Dept Biomed Syst Informat, Biostat Collaborat Unit, Coll Med, Seoul, South Korea | ; Park, Jun/H-7127-2019; Kim, Dong/F-4608-2014; Lee, Hye/D-9081-2016; Ahn, Sang Hoon/AFM-2603-2022; Kim, Sun/L-4239-2013; Lee, Jinae/LTZ-3314-2024; SANG-HOON, AHN/AAV-2600-2020; Lee, Yoojin/AAB-9799-2022; Kim, Nayoung/J-5387-2012 | 57200110315; 57191674344; 55716877100; 59512296200; 57117289600; 54933821200; 47861376300; 56119929100; 7401989551; 35302925200 | beomkkim@yuhs.ac; | LIVER INTERNATIONAL | LIVER INT | 1478-3223 | 1478-3231 | 40 | 7 | SCIE | GASTROENTEROLOGY & HEPATOLOGY | 2020 | 5.828 | 26.6 | 1.1 | 2025-06-25 | 30 | 33 | antiviral therapy; hepatitis B; hepatocellular carcinoma; prediction; virological response | TRANSIENT ELASTOGRAPHY; LIVER STIFFNESS; RISK; CIRRHOSIS; ENTECAVIR; CAUCASIANS; GUIDELINES; MANAGEMENT; TENOFOVIR; FIBROSCAN | antiviral therapy; hepatitis B; hepatocellular carcinoma; prediction; virological response | adefovir; albumin; clevudine; entecavir; hepatitis B(e) antigen; lamivudine; telbivudine; tenofovir; virus DNA; adult; albumin blood level; antiviral therapy; Article; chronic hepatitis B; clinical evaluation; clinical outcome; cohort analysis; decompensated liver cirrhosis; echography; female; follow up; human; intermediate risk patient; liver cell carcinoma; liver cirrhosis; liver stiffness; low risk population; major clinical study; male; platelet count; portal hypertension; prediction; predictive value; prognosis; sensitivity and specificity; transient elastography; viremia | English | 2020 | 2020-07 | 10.1111/liv.14451 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Association between non-alcoholic fatty liver disease and risk of new-onset atrial fibrillation in healthy adults | Background & Aims Previous studies demonstrated conflicting results regarding the association between non-alcoholic fatty liver disease (NAFLD) and atrial fibrillation (AF). The statistical power was not sufficient because of modest sample sizes of these studies. We analysed a large population-based cohort to evaluate the association between NAFLD and AF. Methods We evaluated 334 280 healthy individuals without comorbidities who underwent National Health check-ups in South Korea from 2009 to 2014. NAFLD was defined by a surrogate marker, the fatty liver index (FLI). The association between FLI and AF incidence was analysed using multivariate Cox proportional hazards regression models. Results During a median follow-up of 5.3 years, 1415 subjects (0.4%) were newly diagnosed with AF. Subjects were categorized into quartile groups according to FLI (range: Q1, 0-4.9; Q2, 5.0-12.5; Q3, 12.6-31.0; Q4, >31.0). The cumulative incidence of AF was significantly higher in subjects with higher FLIs than in those with lower FLIs (Q1, 167 [0.2%]; Q2, 281 [0.3%]; Q3, 470 [0.6%]; Q4, 497 [0.6%]; P < .001). Adjusted hazard ratios (HRs) indicated that a higher FLI was independently associated with an increased risk for AF (HR between Q4 and Q1, 1.35; 95% confidence interval [CI], 1.11-1.63; P = .002). After further adjustment for the interim events (diabetes, hypertension, heart failure and myocardial infarction), this association remained statistically significant (HR between Q4 and Q1, 1.55; 95% CI, 1.19-2.03; P = .001). Conclusions NAFLD, assessed by FLI, was independently associated with increased risk for AF in healthy Korean population. Moreover, NAFLD itself predisposes to AF independently of the interim events. | Roh, Jae-Hyung; Lee, Jae-Hwan; Lee, Hanbyul; Yoon, Yong-Hoon; Kim, Minsu; Kim, Yong-Giun; Park, Gyung-Min; Park, Jae-Hyeong; Seong, In-Whan | Chungnam Natl Univ, Chungnam Natl Univ Hosp, Sch Med, Dept Cardiol Internal Med, Daejeon, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Univ Ulsan, Coll Med, Ulsan Univ Hosp, Dept Cardiol, Ulsan, South Korea | Park, M.J./Y-5611-2019; Park, Jae-Hyeong/AAD-9015-2021 | 57216309871; 36066387900; 59107079300; 56038479700; 57208554686; 57207444006; 25924423800; 36063048400; 35254371300 | myheart@cnuh.co.kr; | LIVER INTERNATIONAL | LIVER INT | 1478-3223 | 1478-3231 | 40 | 2 | SCIE | GASTROENTEROLOGY & HEPATOLOGY | 2020 | 5.828 | 26.6 | 0.79 | 2025-06-25 | 27 | 30 | atrial fibrillation; fatty liver index; non-alcoholic fatty liver disease | HEPATIC STEATOSIS; OBESITY | atrial fibrillation; fatty liver index; non-alcoholic fatty liver disease | adult; age; alcohol consumption; Article; cardiovascular risk; cohort analysis; diabetes mellitus; disease association; disease marker; fatty liver index; female; heart failure; heart infarction; human; hypertension; major clinical study; male; never drinker; new-onset atrial fibrillation; nonalcoholic fatty liver; population research; South Korea | English | 2020 | 2020-02 | 10.1111/liv.14236 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
