| ○ | ○ | Article | Anti-inflammatory potential of Lactiplantibacillus plantarum IDCC 3501 and its safety evaluation | This study investigated the anti-inflammatory activity of Lactiplantibacillus plantarum IDCC 3501 isolated from kimchi (Korean fermented food) and its safety. When lipopolysaccharide (LPS)-induced RAW 264.7 macrophages were treated with cell-free supernatant from L. plantarum IDCC 3501, the mRNA expression level of inflammatory markers (i.e., TNF-alpha, IL-1 beta, and IL-6) was significantly reduced. In addition, the decreased cell viability by LPS was recovered and NO production in LPS-induced cell was also decreased. For the safety assessment, the genes responsible for antibiotic resistance and virulence were not detected from the genome analysis of this strain. Consistent with this, minimal inhibitory concentrations against various antibiotics, biogenic amines, and d-lactate production, as well as enzymatic and hemolysis activities, indicated that L. plantarum IDCC 3501 did not produce any harmful compounds during fermentation. Furthermore, no acute toxicity and mortality were observed in a murine mouse model. Based on our findings, L. plantarum IDCC 3501 is safe and beneficial for human consumption. | Yang, Soo-Yeon; Chae, Seung A.; Bang, Won Yeong; Lee, Minjee; Ban, O-Hyun; Kim, Soo-Jung; Jung, Young Hoon; Yang, Jungwoo | Ildong Biosci, 17 Poseunggongdan Ro, Pyeongtaek Si 17957, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Chonnam Natl Univ, Dept Integrat Food Biosci & Biotechnol, Gwangju 61186, South Korea | ; Jung, Young Hoon/F-1703-2013; Jung, Young/F-1703-2013 | 57219223890; 57219223373; 57208701768; 57221979843; 57219226382; 57092299400; 55550063700; 56076383700 | younghoonjung@knu.ac.kr;yjw@ildong.com; | BRAZILIAN JOURNAL OF MICROBIOLOGY | BRAZ J MICROBIOL | 1517-8382 | 1678-4405 | 52 | 4 | SCIE | MICROBIOLOGY | 2021 | 2.214 | 87.2 | 1.4 | 2025-07-30 | 22 | 21 | Anti-inflammatory; Lactic acid bacteria; Lactiplantibacillus plantarum; Probiotics; Safety evaluation | LACTOBACILLUS-PLANTARUM; ANTIBIOTIC SUSCEPTIBILITY; PROBIOTIC LACTOBACILLUS; FOODS; EFFICACY; COLITIS; STRAINS | Anti-inflammatory; Lactic acid bacteria; Lactiplantibacillus plantarum; Probiotics; Safety evaluation | Animals; Anti-Inflammatory Agents; Lactobacillaceae; Lipopolysaccharides; Mice; Microbial Sensitivity Tests; Probiotics; RAW 264.7 Cells; Safety; antiinflammatory agent; lipopolysaccharide; probiotic agent; animal; chemistry; Lactobacillaceae; microbial sensitivity test; mouse; RAW 264.7 cell line; safety | English | 2021 | 2021-12 | 10.1007/s42770-021-00603-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Craniomaxillofacial Changes Using High-Pull J-Hook Headgear and Mini-Implant Anchorage in Adolescents: A Structural Superimposition Method | Objective: The aim of this study was to compare the craniomaxillofacial changes when using high-pull J-hook headgear (HPJH) and mini-implants (MIs) as maxillary anchorage in adolescents. Study Design: 40 female adolescents with dentoalvolar protrusion were divided into 2 groups; the HPJH group (n=20) and the MI group (n=20). Lateral cephalograms taken before treatment (T0) and after anterior tooth retraction (T1) were superimposed on the stable structures and then craniomaxillofacial changes were evaluated. Results: The cranial base angle, SNB, and facial angle decreased in the HPJH group but increased in the MI group. ANB decreased more in the MI group than in the HPJH group. Mandibular plane angle increased in the HPJH group but decreased in the MI group. Facial height index increased in the MI group while it showed no change in the HPJH group. Mandibular true rotation occurred clockwise in the HPJH group and counterclockwise in the MI group. Maxillary central incisors were intruded and retracted more in the MI group than in the HPJH group. Maxillary first molars were extruded in the HPJH group and were intruded in the MI group. Maxillary first molars were protracted more in the HPJH group than in the MI group. Mandibular central incisors were retracted more in the HPJH group than the MI group. Mandibular first molars were extruded more in the MI group than in the HPJH group. Conclusion: More favorable craniomaxillofacial changes occurred in the MI group than in the HPJH group. | Yun, Sunock; Park, Jae Hyun; Chang, Na-Young; Seo, Hye Young; Sung, Jae-Hyun; Hong, Su-Jeong; Chae, Jong-Moon | Beauty Line Dent Clin, Jinju, South Korea; AT Still Univ, Postgrad Orthodont Program, Arizona Sch Dent & Oral Hlth, Mesa, AZ 85206 USA; Kyung Hee Univ, Grad Sch Dent, Seoul, South Korea; Univ Wonkwang, Sch Dent, Wonkwang Dent Res Inst, Dept Orthodont, Iksan, South Korea; Wonkwang Univ, Sch Big Data & Financial Stat, Coll Nat Sci, Iksan, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Daegu, South Korea; Prime Hanvitt Dent Clin, Daejeon, South Korea | Chae, Jong-Moon/AAK-6624-2020; Kim, Jae/AAY-8167-2020 | 57209499990; 58370073300; 35772274800; 57216635783; 7402626879; 57421860900; 14035042600 | jongmoon@wku.ac.kr; | JOURNAL OF CLINICAL PEDIATRIC DENTISTRY | J CLIN PEDIATR DENT | 1053-4628 | 1557-5268 | 45 | 6 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE;PEDIATRICS | 2021 | 1.338 | 87.3 | 0.45 | 2025-07-30 | 2 | 4 | Mini-implant; High-pull J-hook headgear; Anchorage; Structural superimposition | MAXILLARY SUPERIMPOSITION; ORTHODONTIC DIAGNOSIS; OPEN BITE; GROWTH; DISPLACEMENT; OUTCOMES | Anchorage; High-pull J-hook headgear; Mini-implant; Structural superimposition | Adolescent; Cephalometry; Extraoral Traction Appliances; Female; Humans; Malocclusion, Angle Class II; Mandible; Maxilla; Orthodontic Anchorage Procedures; Tooth Movement Techniques; adolescent; cephalometry; female; human; malocclusion; mandible; maxilla; orthodontic anchorage; orthodontic tooth movement; reverse-pull headgear | English | 2021 | 2021 | 10.17796/1053-4625-45.6.11 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | A NEW CLASSIFICATION OF REAL HYPERSURFACES WITH REEB PARALLEL STRUCTURE JACOBI OPERATOR IN THE COMPLEX QUADRIC | In this paper, first we introduce the full expression of the Riemannian curvature tensor of a real hypersurface M in the complex quadric Q(m) from the equation of Gauss and some important formulas for the structure Jacobi operator R-xi and its derivatives del R-xi under the Levi-Civita connection del of M. Next we give a complete classification of Hopf real hypersurfaces with Reeb parallel structure Jacobi operator, del R-xi(xi) = 0, in the complex quadric Q(m) for m >= 3. In addition, we also consider a new notion of C-parallel structure Jacobi operator of M and give a nonexistence theorem for Hopf real hypersurfaces with C-parallel structure Jacobi operator in Q(m), for m >= 3. | Lee, Hyunjin; Suh, Young Jin | Kyungpook Natl Univ, Res Inst Real & Complex Manifolds RIRCM, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea; Kyungpook Natl Univ, RIRCM, Daegu 41566, South Korea | 55706812200; 7202260479 | lhjibis@hanmail.net;yjsuh@ium.ac.kr; | JOURNAL OF THE KOREAN MATHEMATICAL SOCIETY | J KOREAN MATH SOC | 0304-9914 | 2234-3008 | 58 | 4 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2021 | 0.531 | 87.5 | 0.89 | 2025-07-30 | 4 | 4 | Reeb parallel structure Jacobi operator; C-parallel structure Jacobi operator; singular normal vector field; Kahler structure; complex conjugation; complex quadric | PROJECTIVE-SPACE | C-parallel structure Jacobi operator; Complex conjugation; Complex quadric; Kähler structure; Reeb parallel structure Jacobi operator; Singular normal vector field | English | 2021 | 2021-07 | 10.4134/jkms.j200311 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | UNIQUENESS OF TOPOLOGICAL SOLUTIONS FOR THE GUDNASON MODEL | In this paper, we consider the Gudnason model of N = 2 supersymmetric field theory, where the gauge field dynamics is governed by two Chern-Simons terms. Recently, it was shown by Han et al. that for a prescribed configuration of vortex points, there exist at least two distinct solutions for the Gudnason model in a flat two-torus, where a sufficient condition was obtained for the existence. Furthermore, one of these solutions has the asymptotic behavior of topological type. In this paper, we prove that such doubly periodic topological solutions are uniquely determined by the location of their vortex points in a weak-coupling regime. | Kim, Soojung; Lee, Youngae | Soongsil Univ, Dept Math, Seoul 06978, South Korea; Kyungpook Natl Univ, Teachers Coll, Dept Math Educ, Daegu 41566, South Korea | Lee, Youngae/GPG-2128-2022 | 55862513600; 58239646700 | soojungkim@ssu.ac.kr;youngaelee@knu.ac.kr; | JOURNAL OF THE KOREAN MATHEMATICAL SOCIETY | J KOREAN MATH SOC | 0304-9914 | 2234-3008 | 58 | 4 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2021 | 0.531 | 87.5 | 0 | 2025-07-30 | 0 | 0 | Uniqueness; topological solution; Green representation formula; perturbation; doubly periodic solution | NONTOPOLOGICAL MULTIVORTEX SOLUTIONS; BLOW-UP SOLUTIONS; CHARGED VORTICES; SIMONS; EXISTENCE; SUPERCONDUCTORS; CONFINEMENT; EQUATIONS | Doubly periodic solution; Green representation formula; Perturbation; Topological solution; Uniqueness | English | 2021 | 2021-07 | 10.4134/jkms.j200294 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Noninformative priors for the ratio of variabilities in a bivariate normal population | In this paper, we consider some objective priors for the ratio of variabilities in a bivariate normal distribution. We develop the first and second order matching priors and reference priors. We obtain that the second order matching prior matches the alternative coverage probabilities up to the same order. It is also an HPD matching priors. It turns out that the derived reference priors do not satisfy a second order matching criterion. The simulation result shows that the second order matching prior performs better than reference priors based on matching the target coverage probabilities in a frequentist sense. Finally, we show that the second order matching prior and reference priors produce confidence sets with an expected length shorter than the Cox and Reid adjustment. | Kim, Dal Ho; Kang, Sang Gil; Lee, Woo Dong; Kim, Yongku | Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Sangji Univ, Dept Comp & Data Informat, Wonju, South Korea; Daegu Haany Univ, Premajor Cosmet & Pharmaceut, Gyongsan, South Korea | 57198636658; 56119861400; 8328822200; 47962102500 | dalkim@knu.ac.kr; | JOURNAL OF THE KOREAN STATISTICAL SOCIETY | J KOREAN STAT SOC | 1226-3192 | 2005-2863 | 50 | 3 | SCIE | STATISTICS & PROBABILITY | 2021 | 0.82 | 87.6 | 0 | 2025-07-30 | 0 | 0 | Adjusted likelihoods; Bivariate normal; Matching priors; Reference priors; Ratio of variabilities; Expected length | Adjusted likelihoods; Bivariate normal; Expected length; Matching priors; Ratio of variabilities; Reference priors | English | 2021 | 2021-09 | 10.1007/s42952-021-00119-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Age-Related Variation of Syndecan-1 Levels in Saliva and Plasma of Healthy Individuals | Background: Saliva contains various cells, proteins, and molecules, and it is emerging as a material for diagnosing various diseases. Syndecan-1 (SDC-1) is a member of cell surface heparan sulfate proteoglycans and is mainly expressed in epithelial cells and plasma cells. SDC-1 is known to be associated with various cancers and inflammatory response, but there are few studies related to the change of SDC-1 levels in the saliva and plasma of healthy individuals due to aging process. Methods: The study was conducted on 61 females who were healthy without any metabolic diseases, systemic infection, and oral cavity lesions. The subjects were divided into two groups based on age. Those below 40 years were placed in Group I and those who were 40 years and above were placed in Group II. Saliva was collected according to the guideline and the salivary flow rate (SFR) was determined. SDC-1 levels in the plasma and saliva were measured using a commercially available sandwich ELISA method. Results: Age was significantly different between Group I and II (28.0 +/- 2.5 vs. 47.4 +/- 5.5, p < 0.001). SFR also showed a significant difference between Group I and II [0.32 (0.13 -0.39) vs. 0.25 (0.16 -0.35) ng/mL, p = 0.003]. Salivary SDC-1 level in Group I was significantly higher than that in Group II (p < 0.001). In addition, plasma SDC-1 level in Group I was also higher than that in Group II (p < 0.001). SFR was not significantly correlated as age increased, but it showed a significant negative correlation with salivary SDC-1 (r =-0.607, p < 0.001) and plasma SDC-1 levels (r =-0.373, p = 0.003). Salivary SDC-1 level was significantly correlated with plasma SDC-1 level (r = 0.331, p = 0.012). Conclusions: In the younger group, the SFR, salivary, and plasma SDC-1 levels were significantly higher than in the older group. Salivary and plasma SDC-1 showed significant negative correlation as age increased. Although this study was not conducted on a large scale, it might be thought to provide information on the age-related variation for salivary and plasma SDC-1 levels in the aging process. | Nam, Eon Jeong; Ham, Ji Yeon; Song, Kyung Eun; Won, Dong Il; Lee, Nan Young | Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Rheumatol, Daegu, South Korea; Kyungpook Natl Univ, Dept Lab Med, Chilgok Hosp, 807 Hoguk Ro, Daegu 41404, South Korea; Kyungpook Natl Univ, Dept Clin Pathol, Sch Med, Daegu, South Korea | ; lee, nan/HZM-0321-2023 | 7005824293; 56464754800; 57843936100; 7005166517; 57209204358 | leenanyoung70@gmail.com; | CLINICAL LABORATORY | CLIN LAB | 1433-6510 | 67 | 9 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2021 | 1.053 | 87.9 | 0.05 | 2025-07-30 | 2 | 2 | saliva; aging process; salivary flow rate; salivary SDC-1; plasma SDC-1 | PROTEIN; DIAGNOSIS; STRESS; CD138 | Aging process; Plasma SDC-1; Saliva; Salivary flow rate; Salivary SDC-1 | Enzyme-Linked Immunosorbent Assay; Female; Health Status; Humans; Plasma; Saliva; Syndecan-1; syndecan 1; syndecan 1; adult; aging; Article; controlled study; correlation analysis; enzyme linked immunosorbent assay; female; flow rate; human; human experiment; human tissue; middle aged; mouth cavity; normal human; plasma; practice guideline; protein analysis; protein blood level; protein expression; saliva; saliva analysis; salivation; sandwich ELISA; health status; plasma | English | 2021 | 2021 | 10.7754/clin.lab.2021.210113 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Comparison of Low Voleme and Conventional Sodium Citrate Tubes for Routine Coagulation Testing | Background: Low-volume sample tubes reduce unnecessary blood loss due to repeated blood collection and are more convenient to collect blood from patients with difficult veins. However, different sample tubes may be sources of preanalytical bias, and the corresponding test results may reflect clinically important differences. We compared the new low-volume sodium citrate tube to the conventional sodium citrate tube to determine any significant differences between the two types of tubes for routine coagulation testing. Methods: We collected blood samples from 48 random patients, who were referred for routine coagulation testing, into low-volume (1 mL) and conventional (2.7 mL) sodium citrate tubes. We assayed the samples for prothrombin time (PT), activated partial thromboplastin time (aPTT), and D-dimer using the automated coagulation analyzer. Results: There was excellent correlation (r > 0.97) between the results of the two tubes for PT, aPTT, and D-dimer. The PT and aPTT for the low-volume sodium citrate tube were significantly shorter than those of the conventional sodium citrate tube. There was no statistically significant difference in the results for D-dimer. The percent biases calculated with Bland-Altman analysis were 0.8% for PT and 2.0% for aPTT. Both of them were within the desirable specifications for bias with 2.0% for PT and 2.3% for aPTT. Conclusions: It is imperative to perform local validation before introducing new sodium citrate tubes into the routine blood collection practice. Every laboratory needs to standardize the procedures for evaluation of these tubes. | Chang, Soon Hee | Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Daegu, South Korea | 57222602055 | marta10@hanmail.net; | CLINICAL LABORATORY | CLIN LAB | 1433-6510 | 67 | 7 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2021 | 1.053 | 87.9 | 0 | 2025-07-30 | 0 | 0 | coagulation testing; low-volume sodium citrate tube; validation | BLOOD COLLECTION TUBES; PREANALYTICAL VARIABILITY; VOLUME | Coagulation testing; Low-volume sodium citrate tube; Validation | Blood Coagulation Tests; Blood Specimen Collection; Humans; Partial Thromboplastin Time; Prothrombin Time; Sodium Citrate; citrate sodium; D dimer; fibrinogen; citrate sodium; activated partial thromboplastin time; Article; automation; blood clotting test; blood sampling; clinical article; comparative study; correlational study; human; intermethod comparison; low volume blood sampling; medical examination; prothrombin time; blood clotting test; partial thromboplastin time | English | 2021 | 2021 | 10.7754/clin.lab.2020.201016 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Incidence and Distribution of the Pathogens Causing Central Nervous System Infections at the University Hospital of Korea | Background: The pathogens involved in central nervous system (CNS) infections are various, such as viruses, bacteria, and fungi, so a syndromic approach can be required. In addition, since their rapid and accurate detection is very crucial, molecular diagnostics using cerebrospinal fluid is becoming the emerging standard method. Methods: The study was conducted retrospectively to identify the incidence and distribution patterns of the pathogens according to gender, age, season, and month and to analyze their co-detection from August 2017 to July 2020. It was also conducted to investigate turn-around times (TATs) according to the detection method. The detection methods were FilmArray (R) Meningitis/Encephalitis (M/E) method (FilmArray), Cepheid (R) Xpert EV assay (Xpert), and Multiplex PCR method for five species of bacteria. Results: The overall incidence for at least one pathogen was 13.9% (346/2,496). The highest incidence was shown in age group 4 (3 - 6 years), with 27.4%. The detection rates by FilmArray, Xpert, and Multiplex PCR method were 39.8%, 41.7%, and 0.4%, respectively. Enterovirus (EV) showed the highest incidence rate, which accounted for 37.0%. The distribution of the pathogens according to the age groups were the highest in age group 4, with 47.5% (168/354), followed by 27.4% (97/354) in age group 5. Of the ten cases in which bacteria were detected, S. agalactiae accounted for 60.0% (6/10), most of which occurred in age group 1. E. coli K1, L. monocytogenes, and N. meningitidis were not detected. In the viral distribution, EV accounted for the highest proportion in all age groups. The overall proportion of EV accounted for 87.6% (310/354), followed by human parechovirus with 2.8% (10/354). The most commonly detected season was summer, comprising 75.1%. A total of eight cases of co-detection with two pathogens accounted for 1.6% (8/507) in FilmArray. In FilmArray, all TATs were found to be shorter than Xpert. Conclusions: The information on the incidence and distribution patterns of the pathogens causing CNS infections and their rapid detection are critically important to clinicians in the management of immunocompromised patients, elderly, and children. The expeditious molecular diagnostics for these pathogens would be valuable in medical decisions by clinicians. | Nam, E. J.; Ham, J. Y.; Song, K. E.; Kim, Y. K.; Lee, N.

| ○ | ○ | Article | Inflammatory Markers and Cytokines in Moderate and Critical Cases of COVID-19 | Background: Inflammatory responses have been suggested to be associated with coronavirus disease 2019 (COVID-19). This study investigated the inflammatory markers and cytokines in COVID-19 according to its severity. Methods: We enrolled 49 patients with COVID-19, who were classified as either moderate or critical cases. Serum or plasma interleukin (IL)-1 beta, IL-6, and tumor necrosis factor-alpha (TNF-alpha) levels were measured. Results: Lactate dehydrogenase, ferritin, C-reactive protein, and procalcitonin levels were significantly higher in the critical group than in the moderate group (p < 0.001). IL-6 and TNF-alpha levels were significantly higher in the critical group, with elevated IL-6 levels from the first to third weeks after confirmed PCR (p < 0.05). Conclusions: Inflammatory markers and cytokines were increased in COVID-19 and closely related to the severity of the disease. We recommend early active monitoring of IL-6 levels along with inflammatory markers for severe COVID-19. | Chang, Soon Hee; Minn, Dohsik; Kim, Shin-Woo; Kim, Yu Kyung | Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Daegu, South Korea; Seegene Med Fdn, Dept Diagnost Immunol, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea | Kim, Young-Il/ISS-7678-2023 | 57222602055; 57223127194; 8710731500; 9237571900 | kimukn@hanmail.net; | CLINICAL LABORATORY | CLIN LAB | 1433-6510 | 67 | 9 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2021 | 1.053 | 87.9 | 0.57 | 2025-07-30 | 12 | 13 | COVID-19; inflammatory marker; cytokine; interleukin-6; severity | SEVERITY; INTERLEUKIN-6 | COVID-19; Cytokine; Inflammatory marker; Interleukin-6; Severity | Biomarkers; COVID-19; Cytokines; Humans; SARS-CoV-2; Severity of Illness Index; Tumor Necrosis Factor-alpha; biological marker; C reactive protein; cytokine; ferritin; interleukin 1beta; interleukin 6; lactate dehydrogenase; procalcitonin; tumor necrosis factor; biological marker; cytokine; tumor necrosis factor; adult; aged; Article; clinical article; controlled study; coronavirus disease 2019; disease severity; female; human; male; polymerase chain reaction; protein blood level; severity of illness index | English | 2021 | 2021 | 10.7754/clin.lab.2021.210142 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Severe Acute Respiratory Syndrome Coronavirus-2 Antibody Responses in Hospitalized Patients with Coronavirus Disease 2019 in Daegu, Korea | Background: Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) started to spread in Daegu beginning at the end of February 2020. IgG and IgM antibodies against SARS-CoV-2 were measured in hospitalized patients with COVID-19 with moderate to severe symptoms to improve the understanding of antibody responses. Methods: We enrolled 312 patients with COVID-19 admitted to seven hospitals located in Daegu. Using serum (or plasma) samples from patients with polymerase chain reaction ( PCR)-confirmed SARS-CoV-2 infections, both IgG and IgM antibodies were measured using commercial enzyme-linked immunosorbent assay (R-FIND COVID-19 ELISA, SG medical, Seoul, Korea). Results: The median value from the initial diagnosis, confirmed by SARS-CoV-2 PCR, to the sampling date was 24 days (day 1 to 88). The total positive rate of IgG was 93.9% and the positive IgM rate was 39.4%, without considering the elapsed period after diagnosis. Positive IgG and IgM rates were highest at 100.0% and 59.0%, respectively, at 3 weeks (15 - 21 days). IgG showed a high positive rate of 79.3% even within 7 days after the initial diagnosis of the disease and maintained a positive rate of 97.8% until after 8 weeks. Conclusions: Among hospitalized patients with COVID-19, IgG was detected from the beginning of the diagnosis and persisted for an extended time period. | Kim, Yu Kyung; Minn, Dohsik; Yoo, Eun-Hyung; Park, Mikyoung; Lee, Jae Hee; Ha, Jung-Sook; Ham, Ji Yeon; Chang, Soon Hee; Lee, Hyun Chul; Suh, Jang Soo; Jeon, Chang-Ho; Kim, Do-Hoon; Park, Sunggyun; Lee, Nan Young; Song, Kyung Eun; Kim, Soohyun; Kim, Tae Yeob; Kim, Sang-Gyung | Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Daegu, South Korea; Seegene Med Fdn, Dept Diagnost Immunol, Seoul, South Korea; Daegu Catholic Univ Hosp, Dept Lab Med, 33 Duryugongwon Ro 17-gil, Daegu 42472, South Korea; Yeungnam Univ, Dept Lab Med, Coll Med, Daegu, South Korea; Keimyung Univ, Dept Lab Med, Daegu Dongsan Hosp, Daegu, South Korea; Keimyung Univ, Dept Lab Med, Sch Med, Daegu, South Korea; Daegu Fatima Hosp, Dept Lab Med, Daegu, South Korea; Seegene Med Fdn, Dept Lab Med, Daegu, South Korea | ; Kim, Mi-Kyung/E-8682-2012; Kim, Young-Il/ISS-7678-2023; Park, Mikyoung/GWV-7974-2022; Lee, YoungMi/JCF-0461-2023; lee, nan/HZM-0321-2023 | 9237571900; 57223127194; 7006609233; 57233603600; 57226163939; 35754705000; 56464754800; 57222602055; 57192499630; 57201729629; 35082040600; 56972838700; 57216947436; 57209204358; 57843936100; 57390337900; 57390344600; 7601590190 | sgkim@cu.ac.kr; | CLINICAL LABORATORY | CLIN LAB | 1433-6510 | 67 | 11 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2021 | 1.053 | 87.9 | 0 | 2025-07-30 | 0 | 0 | COVID-19; SARS-CoV-2 PCR; ELISA; antibody response | Antibody re-sponse; COVID-19; ELISA; SARS-CoV-2 PCR | Antibodies, Viral; Antibody Formation; COVID-19; Enzyme-Linked Immunosorbent Assay; Humans; Immunoglobulin G; Immunoglobulin M; Republic of Korea; SARS-CoV-2; Sensitivity and Specificity; immunoglobulin G antibody; immunoglobulin M antibody; SARS-CoV-2 antibody; immunoglobulin G; immunoglobulin M; virus antibody; adult; aged; antibody response; Article; cohort analysis; controlled study; coronavirus disease 2019; disease severity; enzyme linked immunosorbent assay; extracorporeal oxygenation; female; hospital admission; hospital patient; human; immunoassay; Korea; major clinical study; male; middle aged; multicenter study; optical density; polymerase chain reaction; positivity rate; antibody production; sensitivity and specificity; South Korea | English | 2021 | 2021 | 10.7754/clin.lab.2021.210305 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Cold-shock gene cspC in the genome of Massilia polaris sp. nov. revealed cold-adaptation | A straw coloured, motile and Gram-stain-negative bacterium, designated RP-1-19(T) was isolated from soil of Arctic station, Svalbard, Norway. Based on the phylogenetic analysis of its 16S rRNA gene sequence, strain RP-1-19(T) formed a lineage within the family Oxalobacteraceae and clustered together within the genus Massilia. The closest members were M. violaceinigra B2(T) (98.6% sequence similarity), M. eurypsychrophilia JCM 30074(T) (98.3%) and M. atriviolacea SODT (98.1%). The only respiratory quinone was ubiquinone-8. The principal cellular fatty acids were summed feature 3 (iso-C-15:0 2-OH/C-16:1 omega 7c) and C-16:0. The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The DNA G + C content of the type strain was 63.2%. The average nucleotide identity and in silico DNA-DNA hybridization values between strain RP-1-19(T) and closest members were <= 80 and 23.2%, respectively. The genome was 4,522,469 bp long with 30 scaffolds and 4076 protein-coding genes. The genome showed eight putative biosynthetic gene clusters responsible for various secondary metabolites. Genome analysis revealed the presence of cold-shock proteins CspA and CspC. Presence of cspA and cspC genes in the genome manifest ecophysiology of strain RP-1-19(T) that may help in cold-adaptation. Based on these data, strain RP-1-19(T) represents a novel species in the genus Massilia, for which the name Massilia polaris sp. nov. is proposed. The type strain is RP-1-19(T) (= KACC 21619(T) = NBRC 114359(T)). | Dahal, Ram Hari; Chaudhary, Dhiraj Kumar; Kim, Dong-Uk; Kim, Jaisoo | Kyonggi Univ, Dept Life Sci, Coll Nat Sci, Suwon 16227, Kyonggi Do, South Korea; Kyungpook Natl Univ, Sch Med, Dept Microbiol, Daegu 41944, South Korea; Korea Univ, Dept Environm Engn, Sejong Campus, Sejong City 30019, South Korea; Sangji Univ, Dept Biol Sci, Coll Sci & Engn, Wonju, South Korea | Chaudhary, Dhiraj/S-7772-2016; Dahal, Ram Hari/H-8673-2016 | 57110097800; 57191257432; 57206099551; 8718834500 | jkimtamu@kgu.ac.kr; | ANTONIE VAN LEEUWENHOEK INTERNATIONAL JOURNAL OF GENERAL AND MOLECULAR MICROBIOLOGY | ANTON LEEUW INT J G | 0003-6072 | 1572-9699 | 114 | 8 | SCIE | MICROBIOLOGY | 2021 | 2.158 | 88.0 | 0.43 | 2025-07-30 | 8 | 7 | Massilia polaris; Arctic soil; Cold-adaptation; Psychrotolerant; Ecophysiology | EMENDED DESCRIPTION; ALGORITHM; ANNOTATION; SERVER; SOIL | Arctic soil; Cold-adaptation; Ecophysiology; Massilia polaris; Psychrotolerant | Bacterial Typing Techniques; Base Composition; DNA, Bacterial; Fatty Acids; Oxalobacteraceae; Phospholipids; Phylogeny; RNA, Ribosomal, 16S; Sequence Analysis, DNA; bacterial protein; bacterial RNA; cardiolipin; cold shock protein; CspA protein; CspC protein; phosphatidylethanolamine; phosphatidylglycerol; quinone derivative; ribosome RNA; ubiquinone 8; ubiquinone derivative; unclassified drug; bacterial DNA; fatty acid; phospholipid; RNA 16S; Article; average nucleotide identity; bacterial gene; bacterial genome; bacterial strain; cold acclimatization; computer analysis; cspA gene; cspC gene; DNA DNA hybridization; ecophysiology; gene and nucleic acid parameters; gene cluster; gene sequence; gene structure; Gram negative bacterium; lipid composition; Massilia atriviolacea; Massilia eurypsychrophilia; Massilia polaris; Massilia violaceinigra; nonhuman; Norway; Oxalobacteraceae; phylogeny; sequence homology; bacterium identification; DNA base composition; DNA sequence; genetics; Oxalobacteraceae | English | 2021 | 2021-08 | 10.1007/s10482-021-01600-z | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Evaluation of the fatigue life of a tractor's transmission spiral bevel gear | Conventional tractor transmission spiral bevel gears are designed and evaluated based on the engine rated load, which is significantly higher than the load conditions in the field. In this study, the fatigue life of a spiral bevel gear is evaluated to obtain data for design optimization. The equivalent load was calculated using the field load data, and the integrated equivalent load was calculated based on the annual usage of major field operations in Korea. The fatigue life of three spiral bevel gear samples was evaluated using the accelerated life test (ALT) under an engine rated load condition of 120%. It was also evaluated under engine rated, plow equivalent, and integrated equivalent load. Fatigue life was estimated using the ALT results and the fatigue damage exponent based on the ALT equation. We observed that the fatigue life of the spiral bevel gear under the plow equivalent and integrated equivalent loads is higher than that under the rated load by 214 and 9,400 times, respectively. The results of this study can provide useful information for the design optimization of tractor transmission spiral bevel gears considering the field equivalent load. (C) 2020 ISTVS.

| ○ | ○ | Article | Metabacillus elymi sp. nov., isolated from the Rhizosphere of Elymus tsukushiensis, a plant native to the Dokdo Islands, Republic of Korea | Dokdo islands in Republic of Korea, is not suited to survive plant because strong wind, low organic content and high salinity. Nevertheless, 64 taxa of plants have a symbiotic relationship with microbe. The Metabacillus elymi KUDC1714(T) was isolated from the rhizosphere of Elymus tsukushiensis collected from Dokdo Islands. This bacterial strain was Gram-stain positive, non-motile, non-spore forming, aerobic and rod-shape bacteria with 0.4-0.5 x 2.5-3.0 mu m in size. Colonies were smooth, yellowish-white circular and 2.0-3.0 mm in diameter. KUDC1714(T) was capable of growing at 10-45 degrees C (optimum, 30 degrees C), pH 7-11 (optimum, pH 8) and 0-8.0% (w/v) NaCl (optimum, 1.0-2.0%). Flagella were not observed by transmission electron microscopy. Phylogenetic analyses, based on 16S rRNA gene sequences, showed that KUDC1714(T) belonged to the genus Metabacillus formed a phyletic lineage within the genus Metabacillus of the family Bacillaceae. The strain KUDC1714(T) was most closely related to Metabacillus sediminilitoris DSL-17( T) (98.2%), Metabacillus litoralis SW-211( T) (98.2%) and Metabacillus halosaccharovorans E33(T) (97.7%) based on 16S rRNA gene sequence. In silico DNA-DNA hybridization using genome-to-genome distance calculator were analysed at 25.8% and 23.5% in strain KUDC1714(T) and Metabacillus sediminilitoris DSL-17( T), and strain KUDC1714(T) and Metabacillus litoralis SW-211( T), respectively. Strain KUDC1714(T) and its closet type strain were all below cut-off point of the average nucleotide identity and average amino acid identity values. The genome contains 5197 CDSs, 3 rRNAs, 118 tRNAs, 5 ncRNAs. The genomic DNA G + C content was 34.8 mol%. Its polar lipids were diphosphatidylglycerol, phosphatidylglycerol and its major fatty acids were anteiso-C-15:0 and iso-C-15:0. The strain KUDC1714(T) contained menaquinone-7 as major isoprenoid quinone. Based on its genetic data, physiological and biochemical characteristics, strain KUDC1714(T) should be considered a novel species of the genus Metabacillus, for which we propose the name Metabacillus elymi sp. nov. the type strain is KUDC1714(T) (= KCTC 33222( T), = DSM 27608( T)). | Lee, Soo-Yeong; Son, Jin-Soo; Hwang, Ye-Ji; Shin, Jae-Ho; Ghim, Sa-Youl | Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat BioRes Grp, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Life Sci, Res Inst Dokdo & Ulleung Do Isl, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, 80 Daehakro, Daegu BUKGU, South Korea | shin, Jaeho/K-6792-2013 | 57205313627; 55311904400; 55279513600; 57224125922; 7003577307 | ghimsa@knu.ac.kr; | ANTONIE VAN LEEUWENHOEK INTERNATIONAL JOURNAL OF GENERAL AND MOLECULAR MICROBIOLOGY | ANTON LEEUW INT J G | 0003-6072 | 1572-9699 | 114 | 10 | SCIE | MICROBIOLOGY | 2021 | 2.158 | 88.0 | 0.28 | 2025-07-30 | 4 | 4 | Metabacillus; Dokdo Islands; Plant rhizosphere; Novel species | BACTERIUM; GENOME; SAMPLE; SEA | Dokdo Islands; Metabacillus; Novel species; Plant rhizosphere | Bacterial Typing Techniques; DNA, Bacterial; Elymus; Islands; Phylogeny; Republic of Korea; Rhizosphere; RNA, Ribosomal, 16S; Sequence Analysis, DNA; Soil Microbiology; bacterial DNA; cardiolipin; cytosine; fatty acid; genomic DNA; guanine; menaquinone; phosphatidylglycerol; ribosome RNA; RNA 16S; sodium chloride; transfer RNA; untranslated RNA; bacterial DNA; RNA 16S; aerobic bacterium; amino acid sequence; Article; Bacillaceae; bacterial flagellum; bacterial growth; bacterial strain; bacterium colony; bacterium isolation; biochemistry; chemotaxonomy; computer model; DNA base composition; DNA DNA hybridization; Elymus; Elymus tsukushiensis; gene sequence; genetic distance; genus; Gram positive bacterium; Gram staining; lipid composition; Metabacillus elymi; Metabacillus halosaccharovorans; Metabacillus litoralis; Metabacillus sediminilitoris; nonhuman; nucleotide sequence; nucleotide sequence; pH; phylogeny; rhizosphere; sequence analysis; South Korea; strain difference; temperature; transmission electron microscopy; bacterium identification; DNA sequence; genetics; island (geological); microbiology; South Korea | English | 2021 | 2021-10 | 10.1007/s10482-021-01634-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
