| ○ | ○ | Article | Mitigating phytotoxicity of tetracycline by metal-free 8-hydroxyquinoline functionalized carbon nitride photocatalyst | Photooxidative removal of pharmaceuticals and organic dyes is an effective way to elimi-nate growing micropollutants. However, photooxidation often results in byproducts as sec-ondary hazardous substances such as phytotoxins. Herein, we found that photooxidation of common antibiotic tetracycline hydrochloride (TCH) over a metal-free 8-hydroxyquinoline (8-HQ) functionalized carbon nitride (CN) photocatalyst significantly reduces the TCH phy-totoxic effect. The phytotoxicity test of photocatalytic treated TCH-solution evaluated to-wards seed growth of Cicer arietinum plant model endowed natural root and shoot growth. This study highlights the conceptual insights in designing of metal-free photocatalyst for environmental remediation.

| ○ | Article | The clinical course of hospitalized COVID-19 patients and aggravation risk prediction models: a retrospective, multi-center Korean cohort study | Background: Understanding the clinical course and pivotal time points of COVID-19 aggravation is critical for enhancing patient monitoring. This retrospective, multi-center cohort study aims to identify these significant time points and associate them with potential risk factors, leveraging data from a sizable cohort with mild-to-moderate symptoms upon admission. Methods: This study included data from 1,696 COVID-19 patients with mild-to-moderate clinical severity upon admission across multiple hospitals in Daegu-Kyungpook Province (Daegu dataset) between February 18 and early March 2020 and 321 COVID-19 patients at Seoul Boramae Hospital (Boramae dataset) collected from February to July 2020. The approach involved: (1) identifying the optimal time point for aggravation using survival analyses with maximally selected rank statistics; (2) investigating the relationship between comorbidities and time to aggravation; and (3) developing prediction models through machine learning techniques. The models were validated internally among patients from the Daegu dataset and externally among patients from the Boramae dataset. Results: The Daegu dataset showed a mean age of 51.0 ± 19.6 years, with 8 days for aggravation and day 5 being identified as the pivotal point for survival. Contrary to previous findings, specific comorbidities had no notable impact on aggravation patterns. Prediction models utilizing factors including age and chest X-ray infiltration demonstrated promising performance, with the top model achieving an AUC of 0.827 in external validation for 5 days aggravation prediction. Conclusion: Our study highlights the crucial significance of the initial 5 days period post-admission in managing COVID-19 patients. The identification of this pivotal time frame, combined with our robust predictive models, provides valuable insights for early intervention strategies. This research underscores the potential of proactive monitoring and timely interventions in enhancing patient outcomes, particularly for those at risk of rapid aggravation. Our findings offer a meaningful contribution to understanding the COVID-19 clinical course and supporting healthcare providers in optimizing patient care and resource allocation.

| ○ | ○ | Article | Whole-body imaging of Camponotus atrox using photoacoustic microscopy for three-dimensional morphological analysis: A preliminary study | Whole-body image analysis has been extensively applied in the field of entomology to identify differences in insect morphology. Although various conventional imaging techniques have been used for analyzing insect morphology, these often inflict damage on the sample during preparation and limitedly provide superficial in-formation. To overcome the conventional limitations, in this study, we noninvasively observed the morpho-logical structures of the ant Camponotus atrox, from the whole body to specific parts, over a wide scan range using optical-resolution photoacoustic microscopy (PAM). Based on the obtained photoacoustic maximum amplitude projection images, various structures of the ant, including the antenna, compound eyes, coxa, mandibles, mes-onotum, propodeum, petiole, sting, and tergite, could be discerned by covering the entire ant body. In addition, we attained the morphological structures in detail by magnifying three specific parts, namely, the compound eyes, head, and thorax. Furthermore, we non-destructively analyzed the internal structure of various organs, such as the compound eyes, social stomach, and hindgut, via depth profiling of cross-sectional images. Finally, by implementing an algorithm, we visualized the depth-resolved en-face images of internal structures according to a constant depth interval. The findings established that the PAM system could identify not only each external morphological feature of the ant visible but also the sublayers of its internal structures. This study demonstrates the feasibility of PAM for contributing to performing morphological studies in entomological research. | Kim, Hyunmo; Seong, Daewoon; Han, Sangyeob; Cho, Hoseong; Lee, Jaeyul; Wijesinghe, Ruchire Eranga; Jeon, Mansik; Kim, Jeehyun | Kyungpook Natl Univ, Coll IT Engn, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, ICT Convergence Res Ctr, 80 Daehak Ro, Daegu 41566, South Korea; Univ Calif Los Angeles, Dept Bioengn, Los Angeles, CA 90095 USA; Univ Sri Jayewardenepura, Fac Technol, Dept Mat & Mech Technol, Pitipana 10200, Homagama, Sri Lanka | Wijesinghe, Ruchire/K-3797-2016; Lee, Junsoo/IUO-9627-2023; Han, Sangyeob/W-3206-2018 | 58078407800; 57212512353; 57193695305; 57209416599; 57188689420; 57214877268; 24171094000; 7601373350 | msjeon@knu.ac.kr;jeehk@knu.ac.kr; | OPTICS AND LASER TECHNOLOGY | OPT LASER TECHNOL | 0030-3992 | 1879-2545 | 167 | SCIE | OPTICS;PHYSICS, APPLIED | 2023 | 4.6 | 17.2 | 0.27 | 2025-06-25 | 2 | 2 | Ant; Camponotus atrox; Whole-body imaging; Morphology; Optical imaging; Photoacoustic microscopy | HYMENOPTERA-FORMICIDAE; HIGH-RESOLUTION; ANT; TOMOGRAPHY; LIMITATIONS; ECOLOGY; CT | Ant; Camponotus atrox; Morphology; Optical imaging; Photoacoustic microscopy; Whole-body imaging | Antennas; Depth profiling; Image analysis; Photoacoustic microscopy; Ant; Body image; Camponotu atrox; Compound eye; Internal structure; Morphological analysis; Morphological structures; Optical imaging; Whole-body; Whole-body imaging; Morphology | English | 2023 | 2023-12 | 10.1016/j.optlastec.2023.109754 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A Search for Pulsars around Sgr A* in the First Event Horizon Telescope Data Set | In 2017 the Event Horizon Telescope (EHT) observed the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), at a frequency of 228.1 GHz (lambda = 1.3 mm). The fundamental physics tests that even a single pulsar orbiting Sgr A* would enable motivate searching for pulsars in EHT data sets. The high observing frequency means that pulsars-which typically exhibit steep emission spectra-are expected to be very faint. However, it also negates pulse scattering, an effect that could hinder pulsar detections in the Galactic center. Additionally, magnetars or a secondary inverse Compton emission could be stronger at millimeter wavelengths than at lower frequencies. We present a search for pulsars close to Sgr A* using the data from the three most sensitive stations in the EHT 2017 campaign: the Atacama Large Millimeter/submillimeter Array, the Large Millimeter Telescope, and the IRAM 30 m Telescope. We apply three detection methods based on Fourier-domain analysis, the fast folding algorithm, and single-pulse searches targeting both pulsars and burst-like transient emission. We use the simultaneity of the observations to confirm potential candidates. No new pulsars or significant bursts were found. Being the first pulsar search ever carried out at such high radio frequencies, we detail our analysis methods and give a detailed estimation of the sensitivity of the search. We conclude that the EHT 2017 observations are only sensitive to a small fraction (less than or similar to 2.2%) of the pulsars that may exist close to Sgr A*, motivating further searches for fainter pulsars in the region. | Torne, Pablo; Liu, Kuo; Eatough, Ralph P.; Wongphechauxsorn, Jompoj; Cordes, James M.; Desvignes, Gregory; De Laurentis, Mariafelicia; Kramer, Michael; Ransom, Scott M.; Chatterjee, Shami; Wharton, Robert; Karuppusamy, Ramesh; Blackburn, Lindy; Janssen, Michael; Chan, Chi-Kwan; Crew, Geoffrey B.; Matthews, Lynn D.; Goddi, Ciriaco; Rottmann, Helge; Wagner, Jan; Sanchez, Salvador; Ruiz, Ignacio; Abbate, Federico; Bower, Geoffrey C.; Salamanca, Juan J.; Gomez-Ruiz, Arturo I.; Herrera-Aguilar, Alfredo; Jiang, Wu; Lu, Ru-Sen; Pen, Ue-Li; Raymond, Alexander W.; Shao, Lijing; Shen, Zhiqiang; Paubert, Gabriel; Sanchez-Portal, Miguel; Kramer, Carsten; Castillo, Manuel; Navarro, Santiago; John, David; Schuster, Karl-Friedrich; Johnson, Michael D.; Rygl, Kazi L.

| ○ | ○ | Article | ApoE4-dependent lysosomal cholesterol accumulation impairs mitochondrial homeostasis and oxidative phosphorylation in human astrocytes | Recent developments in genome sequencing have expanded the knowledge of genetic factors associated with late-onset Alzheimer's disease (AD). Among them, genetic variant epsilon 4 of the APOE gene (APOE4) confers the greatest disease risk. Dysregulated glucose metabolism is an early pathological feature of AD. Using isogenic ApoE3 and ApoE4 astrocytes derived from human induced pluripotent stem cells, we find that ApoE4 increases glycolytic activity but impairs mitochondrial respiration in astrocytes. Ultrastructural and autophagy flux analyses show that ApoE4-induced cholesterol accumulation impairs lysosome-dependent removal of damaged mitochondria. Acute treatment with cholesterol-depleting agents restores autophagic activity, mitochondrial dynamics, and associated proteomes, and extended treatment rescues mitochondrial respiration in ApoE4 astrocytes. Taken together, our study provides a direct link between ApoE4-induced lysosomal cholesterol accumulation and abnormal oxidative phosphorylation. | Lee, Hyein; Cho, Sukhee; Kim, Mi-Jin; Park, Yeo Jin; Cho, Eunji; Jo, Yeon Suk; Kim, Yong-Seok; Lee, Jung Yi; Thoudam, Themis; Woo, Seung-Hwa; Lee, Se-In; Jeon, Juyeong; Lee, Young-Sam; Suh, Byung-Chang; Yoon, Jong Hyuk; Go, Younghoon; Lee, In-Kyu; Seo, Jinsoo | Daegu Gyeongbuk Inst Sci & Technol, Dept Brain Sci, Daegu 42988, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Leading Edge Res Ctr Drug Discovery & Dev Diabet &, Sch Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Res Inst Aging & Metab, Daegu 41944, South Korea; Univ Sci & Technol, Korean Med Life Sci, Daejeon 34054, South Korea; Korea Inst Oriental Med, Korean Med Applicat Ctr, Daegu 41062, South Korea; Korea Brain Res Inst, Neurodegenerat Dis Res Grp, Daegu 41062, South Korea; Daegu Gyeongbuk Inst Sci & Technol, Dept New Biol, Daegu 42988, South Korea | ; Seo, Jinsoo/AAD-4950-2019; thoudam, themis/ACM-3919-2022 | 57212057493; 55801815000; 58364690500; 57196349389; 55863428700; 57343806700; 57216975471; 57195563161; 57192905626; 57225025140; 57253049800; 58622080700; 56328278900; 7103193835; 57212513350; 55455882000; 36071537600; 7401783716 | gotra827@kiom.re.kr;leei@knu.ac.kr;jsseo@dgist.ac.kr; | CELL REPORTS | CELL REP | 2211-1247 | 42 | 10 | SCIE | CELL BIOLOGY | 2023 | 7.5 | 17.3 | 2.29 | 2025-06-25 | 31 | 23 | BRAIN AEROBIC GLYCOLYSIS; METHYL-BETA-CYCLODEXTRIN; ALZHEIMERS-DISEASE; PATTERNS; APOE | ApoE4; CP: Cell biology; CP: Metabolism; glucose metabolism; human astrocytes; lysosomal cholesterol accumulation; mitophagy | Alzheimer Disease; Apolipoprotein E3; Apolipoprotein E4; Apolipoproteins E; Astrocytes; Cells, Cultured; Cholesterol; Humans; Induced Pluripotent Stem Cells; Oxidative Phosphorylation; apolipoprotein E3; apolipoprotein E4; cholesterol; apolipoprotein E; apolipoprotein E3; apolipoprotein E4; cholesterol; aged; animal cell; ApoE4 gene; Article; astrocyte; autophagy (cellular); cell damage; cell ultrastructure; cholesterol metabolism; clinical article; controlled study; female; glycolysis; human; human cell; induced pluripotent stem cell; lysosome; mitochondrial dynamics; mitochondrial respiration; mouse; nonhuman; oxidative phosphorylation; proteomics; very elderly; Alzheimer disease; astrocyte; cell culture; genetics; induced pluripotent stem cell; metabolism; oxidative phosphorylation | English | 2023 | 2023-10-31 | 10.1016/j.celrep.2023.113183 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Comparison of Polarized Radiative Transfer Codes Used by the EHT Collaboration | Interpretation of resolved polarized images of black holes by the Event Horizon Telescope (EHT) requires predictions of the polarized emission observable by an Earth-based instrument for a particular model of the black hole accretion system. Such predictions are generated by general relativistic radiative transfer (GRRT) codes, which integrate the equations of polarized radiative transfer in curved spacetime. A selection of ray-tracing GRRT codes used within the EHT Collaboration is evaluated for accuracy and consistency in producing a selection of test images, demonstrating that the various methods and implementations of radiative transfer calculations are highly consistent. When imaging an analytic accretion model, we find that all codes produce images similar within a pixel-wise normalized mean squared error (NMSE) of 0.012 in the worst case. When imaging a snapshot from a cell-based magnetohydrodynamic simulation, we find all test images to be similar within NMSEs of 0.02, 0.04, 0.04, and 0.12 in Stokes I, Q, U, and V, respectively. We additionally find the values of several image metrics relevant to published EHT results to be in agreement to much better precision than measurement uncertainties. | Prather, Ben S.; Dexter, Jason; Moscibrodzka, Monika; Pu, Hung-Yi; Bronzwaer, Thomas; Davelaar, Jordy; Younsi, Ziri; Gammie, Charles F.; Gold, Roman; Wong, George N.; Akiyama, Kazunori; Alberdi, Antxon; Alef, Walter; Algaba, Juan Carlos; Anantua, Richard; Asada, Keiichi; Azulay, Rebecca; Bach, Uwe; Baczko, Anne-Kathrin; Ball, David; Balokovic, Mislav; Barrett, John; Bauboeck, Michi A.; Benson, Bradford; Bintley, Dan; Blackburn, Lindy; Blundell, Raymond L.; Bouman, Katherine C.; Bower, Geoffrey; Boyce, Hope; Bremer, Michael D.; Brinkerink, Christiaan; Brissenden, Roger; Britzen, Silke E.; Broderick, Avery; Broguiere, Dominique; Bustamante, Sandra; Byun, Do-Young E.; Carlstrom, John; Ceccobello, Chiara; Chael, Andrew; Chan, Chi-kwan O.; Chang, Dominic; Chatterjee, Koushik; Chatterjee, Shami; Chen, Ming-Tang; Chen, Yongjun; Cheng, Xiaopeng; Cho, Ilje; Christian, Pierre S.; Conroy, Nicholas E.; Conway, John M.; Cordes, James M.; Crawford, Thomas B.; Crew, Geoffrey; Cruz-Osorio, Alejandro; Cui, Yuzhu; De Laurentis, Mariafelicia; Deane, Roger; Dempsey, Jessica; Desvignes, Gregory; Dhruv, Vedant S.; Doeleman, Sheperd; Dougal, Sean A.; Dzib, Sergio P.; Eatough, Ralph; Emami, Razieh; Falcke, Heino; Farah, Joseph L.; Fish, Vincent; Fomalont, Ed; Ford, H.

| ○ | ○ | Article | Deficit of Hot Dust in Low-redshift Active Galactic Nuclei | We assemble a broadband spectral energy distribution (SED) ranging from the optical to the mid-infrared of nearby active galactic nuclei (AGNs) at z < 0.4. The SED fitting analysis is performed using semiempirical templates derived from Palomar-Green quasars to classify the sample into normal, warm-dust-deficient (WDD), and hot-dust-deficient (HDD) AGNs. Kolmogorov-Smirnov tests reveal that HDD AGNs exhibit higher AGN luminosity on average than normal and WDD AGNs. The HDD fraction, on the other hand, is only weakly correlated with the black hole mass and inversely correlated with the Eddington ratio. By fixing the other parameters, we conclude that the HDD fraction is primarily connected with the AGN luminosity. This implies that there is a causal connection between the covering factor of the hot dust component and AGN luminosity, possibly due to the sublimation of the innermost dust or the thickening of the intervening gas in the broad-line region. Analysis of the outflow properties traced by the wing of [O iii]& lambda;5007 suggests that outflows may be related to the formation and maintenance of the hot dust component. Finally, we demonstrate through comparison with previous studies that the classification of HDD AGNs requires careful subtraction of the host galaxy light. | Son, Suyeon; Kim, Minjin; Ho, Luis C. | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 702701, South Korea; Peking Univ, Kavli Inst Astron & Astrophys, Beijing 100871, Peoples R China; Peking Univ, Sch Phys, Dept Astron, Beijing 100871, Peoples R China | Kim, Minjin/AAU-9910-2020 | 57226328130; 56898213300; 57225302746 | mkim.astro@gmail.com; | ASTROPHYSICAL JOURNAL | ASTROPHYS J | 0004-637X | 1538-4357 | 953 | 2 | SCIE | ASTRONOMY & ASTROPHYSICS | 2023 | 4.8 | 17.3 | 0.59 | 2025-06-25 | 5 | 5 | SPECTRAL ENERGY-DISTRIBUTIONS; EMISSION-LINE REGION; BLACK-HOLES; REVERBERATION MEASUREMENTS; STELLAR POPULATION; INFRARED-EMISSION; INNER RADIUS; RADIATION PRESSURE; SEYFERT-GALAXIES; COVERING FACTOR | English | 2023 | 2023-08-01 | 10.3847/1538-4357/ace165 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Double SSA spectrum and magnetic field strength of the FSRQ 3C 454.3 | We present the results of a radio multifrequency (3-340 GHz) study of the blazar 3C 454.3. After subtracting the quiescent spectrum corresponding to optically thin emission, we found two individual synchrotron self-absorption (SSA) features in the wide-band spectrum. The one SSA had a relatively low turnover frequency (nu(m)) in the range of 3-37 GHz (lower nu(m) SSA spectrum, LSS), and the other one had a relatively high nu(m) of 55-124 GHz (higher nu(m) SSA spectrum, HSS). Using the SSA parameters, we estimated B-field strengths at the surface where optical depth tau = 1. The estimated B-field strengths were > 7 and > 0.2 mG for the LSS and HSS, respectively. The LSS-emitting region was magnetically dominated before the 2014 June gamma-ray flare. The quasi-stationary component (C), similar to 0.6 mas apart from the 43 -GHz radio core, became brighter than the core with decreasing observing frequency, and we found that component C was related to the LSS. A decrease in jet width was found near component C. As a moving component, K14 approached component C, and the flux density of the component was enhanced while the angular size decreased. The high intrinsic brightness temperature in the fluid frame was obtained as T-B,T- int approximate to (7.0 +/- 1.0) x 10(11) K from the jet component after the 2015 August.-ray flare, suggesting that component C is a high-energy emitting region. The observed local minimum of jet width and re-brightening behaviour suggest a possible recollimation shock in component C. | Jeong, Hyeon-Woo; Lee, Sang-Sung; Cheong, Whee Yeon; Kim, Jae-Young; Lee, Jee Won; Kang, Sincheol; Kim, Sang-Hyun; Rani, B.; Park, Jongho; Gurwell, Mark A. | Univ Sci & Technol, Astron & Space Sci, 217 Gajeong Ro, Daejeon 34113, South Korea; Korea Astron & Space Sci Inst, 776 Daedeok Daero, Daejeon 34055, South Korea; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 702701, South Korea; Max Planck Inst Radioastron, Auf Hugel 69, D-53121 Bonn, Germany; NASA Goddard Space Flight Ctr, Greenbelt, MD 20771 USA; Amer Univ, Dept Phys, Washington, DC 20016 USA; Ctr Astrophys Harvard & Smithsonian, 60 Garden St, Cambridge, MA 02138 USA | Lee, Sang-Sung/AFS-2722-2022; Jeong, Hyeon Woo/HTM-2917-2023; Park, Jongho/JFB-2747-2023; Cheong, Whee Yeon/KCZ-2228-2024; Kim, Sang-hyun/C-1811-2011; Kim, Jae-Young/IUO-6466-2023 | 58260672200; 37056945900; 58150566100; 57211836467; 55870740000; 56023283900; 57219655175; 36125334100; 56953647500; 6602556944 | sslee@kasi.re.kr; | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY | MON NOT R ASTRON SOC | 0035-8711 | 1365-2966 | 523 | 4 | SCIE | ASTRONOMY & ASTROPHYSICS | 2023 | 4.8 | 17.3 | 0.36 | 2025-06-25 | 3 | 3 | galaxies: active; galaxies: jets; quasars: individual: 3C 454.3; radio continuum: galaxies | ACTIVE GALACTIC NUCLEI; PARSEC-SCALE JETS; GAMMA-RAY BLAZARS; CTA 102; RECOLLIMATION SHOCK; KINEMATICS ANALYSIS; FLUX-DENSITY; RADIO FLARE; CORE-SHIFT; FERMI ERA | galaxies: active; galaxies: jets; quasars: individual: 3C 454.3; radio continuum: galaxies | Absorption spectroscopy; Galaxies; B-fields; Component C; Field strengths; Galaxies active; Galaxies jets; Magnetic field strengths; Quasar: individual: 3c 454.3; Quasars: individual; Radio continuum: galaxies; Self absorption; Gamma rays | English | 2023 | 2023-06-22 | 10.1093/mnras/stad1736 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Estimators of Bolometric Luminosity and Black Hole Mass with Mid-infrared Continuum Luminosities for Dust-obscured Quasars: Prevalence of Dust-obscured SDSS Quasars | We present bolometric luminosity (L bol) and black hole (BH) mass (M BH) estimators based on mid-infrared (MIR) continuum luminosity (hereafter, L MIR) that are measured from infrared (IR) photometric data. The L MIR-based estimators are relatively immune from dust extinction effects, hence they can be used for dust-obscured quasars. To derive the L bol and M BH estimators, we use unobscured quasars selected from the Sloan Digital Sky Survey (SDSS) quasar catalog, which have wide ranges of L bol (1044.62-1046.16 erg s-1) and M BH (107.14-109.69 M & ODOT;). We find empirical relations between (i) continuum luminosity at 5100 & ANGS; (hereafter, L5100) and L MIR; (ii) L bol and L MIR. Using these relations, we derive the L MIR-based L bol and M BH estimators. We find that our estimators allow the determination of L bol and M BH at an accuracy of & SIM;0.2 dex against the fiducial estimates based on the optical properties of the unobscured quasars. We apply the L MIR-based estimators to SDSS quasars at z & LSIM; 0.5 including obscured ones. The ratios of L bol from the L MIR-based estimators to those from the optical luminosity-based estimators become larger with the amount of the dust extinction, and a non-negligible fraction (& SIM;15%) of the SDSS quasars exhibits ratios greater than 1.5. This result suggests that dust extinction can significantly affect physical parameter derivations even for SDSS quasars, and that dust extinction needs to be carefully taken into account when deriving quasar properties. | Kim, Dohyeong; Im, Myungshin; Kim, Minjin; Kim, Yongjung; Shin, Suhyun; Shim, Hyunjin; Song, Hyunmi | Pusan Natl Univ, Dept Earth Sci, Busan 46241, South Korea; Seoul Natl Univ, Dept Phys & Astron, Astron Program, Seoul 08826, South Korea; Seoul Natl Univ, SNU Astron Res Ctr SNU ARC, Dept Phys & Astron, Astron Program, Seoul 08826, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Earth Sci Educ, 80 Daehak Ro, Daegu 41566, South Korea; Chungnam Natl Univ, Dept Astron & Space Sci, 99 Daehak Ro, Daejeon 34134, South Korea | ; , Yong Jung Kim/JRW-0681-2023; Kim, Minjin/AAU-9910-2020; Shim, Hyunjin/LZI-7486-2025; Im, Myungshin/B-3436-2013 | 55574223678; 7004267711; 56898213300; 59622148200; 57205483501; 14061137700; 35749280400 | myungshin.im@gmail.com; | ASTROPHYSICAL JOURNAL | ASTROPHYS J | 0004-637X | 1538-4357 | 954 | 2 | SCIE | ASTRONOMY & ASTROPHYSICS | 2023 | 4.8 | 17.3 | 1.07 | 2025-06-25 | 9 | 9 | ACTIVE GALACTIC NUCLEI; SPECTRAL ENERGY-DISTRIBUTIONS; INFRARED-SURVEY-EXPLORER; HOT-DUST; GALAXY MERGERS; RED QUASARS; REVERBERATION MEASUREMENTS; ELLIPTIC GALAXIES; EMISSION-LINE; SKY | English | 2023 | 2023-09-01 | 10.3847/1538-4357/aceb5e | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Feasibility study for the automatic surgical planning method based on statistical model | PurposeIn this study, we proposed establishing an automatic computer-assisted surgical planning approach based on average population models.MethodsWe built the average population models from humerus datasets using the Advanced Normalization Toolkits (ANTs) and Shapeworks. Experiments include (1) evaluation of the average population models before surgical planning and (2) validation of the average population models in the context of predicting clinical landmarks on the humerus from the new dataset that was not involved in the process of building the average population model. The evaluation experiment consists of explained variation and distance model. The validation experiment calculated the root-mean-square error (RMSE) between the expert-determined clinical ground truths and the landmarks transferred from the average population model to the new dataset. The evaluation results and validation results when using the templates built from ANTs were compared to when using the mean shape generated from Shapeworks.ResultsThe average population models predicted clinical locations on the new dataset with acceptable errors when compared to the ground truth determined by an expert. However, the templates built from ANTs present better accuracy in landmark prediction when compared to the mean shape built from the Shapeworks.ConclusionThe average population model could be utilized to assist anatomical landmarks checking automatically and following surgical decisions for new patients who are not involved in the dataset used to generate the average population model. | Nguyen, Hang Phuong; Lee, Hyun-Joo; Kim, Sungmin | Univ Ulsan, Dept Elect Elect & Comp Engn, Ulsan, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Orthopaed Surg, Daegu, South Africa | Lee, Hyun Joo/GVU-6347-2022 | 57450084300; 58838750100; 57835343800 | sungminkim@ulsan.ac.kr; | JOURNAL OF ORTHOPAEDIC SURGERY AND RESEARCH | J ORTHOP SURG RES | 1749-799X | 18 | 1 | SCIE | ORTHOPEDICS | 2023 | 2.8 | 17.3 | 0.29 | 2025-06-25 | 2 | 1 | Template; Statistical shape model; Computer-assisted surgical planning; Clinical decision support | SHAPE MODELS; MRI; REGISTRATION | Clinical decision support; Computer-assisted surgical planning; Statistical shape model; Template | Feasibility Studies; Humans; Humerus; Models, Statistical; feasibility study; human; humerus; statistical model; surgery | English | 2023 | 2023-06-01 | 10.1186/s13018-023-03870-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | First BISTRO Observations of the Dark Cloud Taurus L1495A-B10: The Role of the Magnetic Field in the Earliest Stages of Low-mass Star Formation | We present BISTRO Survey 850 mu m dust emission polarization observations of the L1495A-B10 region of the Taurus molecular cloud, taken at the James Clerk Maxwell Telescope (JCMT). We observe a roughly triangular network of dense filaments. We detect nine of the dense starless cores embedded within these filaments in polarization, finding that the plane-of-sky orientation of the core-scale magnetic field lies roughly perpendicular to the filaments in almost all cases. We also find that the large-scale magnetic field orientation measured by Planck is not correlated with any of the core or filament structures, except in the case of the lowest-density core. We propose a scenario for early prestellar evolution that is both an extension to, and consistent with, previous models, introducing an additional evolutionary transitional stage between field-dominated and matter-dominated evolution, observed here for the first time. In this scenario, the cloud collapses first to a sheet-like structure. Uniquely, we appear to be seeing this sheet almost face on. The sheet fragments into filaments, which in turn form cores. However, the material must reach a certain critical density before the evolution changes from being field dominated to being matter dominated. We measure the sheet surface density and the magnetic field strength at that transition for the first time and show consistency with an analytical prediction that had previously gone untested for over 50 yr. | Ward-Thompson, Derek; Karoly, Janik; Pattle, Kate; Whitworth., Anthony; Kirk, Jason; Berry, David; Bastien, Pierre; Ching, Tao-Chung; Coude, Simon; Hwang, Jihye; Kwon, Woojin; Soam, Archana; Wang, Jia-Wei; Hasegawa, Tetsuo; Lai, Shih-Ping; Qiu, Keping; Arzoumanian, Doris; Bourke, Tyler L.; Byun, Do-Young; Chen, Huei-Ru Vivien; Chen, Wen Ping; Chen, Mike; Chen, Zhiwei; Cho, Jungyeon; Choi, Minho; Choi, Youngwoo; Choi, Yunhee; Chrysostomou, Antonio; Chung, Eun Jung; Dai, Sophia; Debattista, Victor; Di Francesco, James; Diep, Pham Ngoc; Doi, Yasuo; Duan, Hao-Yuan; Duan, Yan; Eswaraiah, Chakali; Fanciullo, Lapo; Fiege, Jason; Fissel, Laura M.; Franzmann, Erica; Friberg, Per; Friesen, Rachel; Fuller, Gary; Furuya, Ray; Gledhill, Tim; Graves, Sarah; Greaves, Jane; Griffin, Matt; Gu, Qilao; Han, Ilseung; Hayashi, Saeko; Hoang, Thiem; Houde, Martin; Hull, Charles L.

| ○ | ○ | Article | Metformin increases the expression of proinflammatory cytokines and inhibits supraspinatus fatty infiltration | Background After a rotator cuff (RC) tendon tear, the supraspinatus (SS) inflammatory response induces fatty infiltration (FI). Metformin has the effect of regulating the initial inflammatory response of atrophic muscles. Therefore, this study aimed to investigate the effect of metformin use on modulating the expression of proinflammatory cytokines and SS FI in an acute RC tear rat model. Methods This study used 26 male Sprague-Dawley rats. Animals were randomly divided into two groups: The metformin group received metformin for 5 days after cutting the RC tendon, and the control group was administered only with saline after cutting the tendon. Metformin 50 mg/kg was intraperitoneally injected for 5 days. Three rats in each group were sacrificed 5 days after SS tendon rupture surgery, and 10 rats in each group were sacrificed 14 days after surgery. The SS was sampled 5 days after SS tendon tear surgery, and the expression of proinflammatory cytokines was measured by quantitative reverse-transcription polymerase chain reaction (qRT-PCR). On day 14 after sampling, histological analysis of the SS was performed using hematoxylin and eosin, Masson's trichrome, and picrosirius red staining. Results On day 5 of surgery, the expression values of interferon gamma (increased 7.2-fold, P <.01), tumor necrosis factor alpha (increased 13-fold, P <.05), interleukin-1 beta (increased 4.7-fold, P <.001), and interleukin-6 (increased 4.6-fold, P <.01) increased significantly in the metformin group compared with those in the control group. As a result of Oil Red O staining, SS FI was significantly suppressed in the metformin group compared with that in the control group (metformin group, 305 +/- 50.3 mu m(2), P <.001; control group, 3136 +/- 662.8 mu m(2), P <.001). In addition, the SS volume of the metformin group was not reduced compared with those of the control group, and the morphology and structure of the SS were better preserved. Conclusions The results of this study revealed that metformin can increase the expression of proinflammatory cytokines and suppress SS fat infiltration in delayed sutures. | Yoon, Jong Pil; Park, Sung-Jin; Kim, Dong-Hyun; Chung, Seok Won | Kyungpook Natl Univ, Sch Med, Dept Orthopaed Surg, Daegu, South Korea; KonKuk Univ, Med Ctr, Dept Orthopaed Surg, Sch Med, Seoul, South Korea | 36098548400; 58527890700; 57198637188; 37065938600 | knuhos_sh2@naver.com; | JOURNAL OF ORTHOPAEDIC SURGERY AND RESEARCH | J ORTHOP SURG RES | 1749-799X | 18 | 1 | SCIE | ORTHOPEDICS | 2023 | 2.8 | 17.3 | 1.45 | 2025-06-25 | 5 | 5 | Metformin; Inflammatory response; Fatty infiltration; Supraspinatus atrophy; Histology; Rotator cuff tear | ROTATOR CUFF REPAIR; DEGENERATION; CELLS; TEARS; ATROPHY; RISK; NEER | Fatty infiltration; Histology; Inflammatory response; Metformin; Rotator cuff tear; Supraspinatus atrophy | Animals; Cytokines; Male; Metformin; Rats; Rats, Sprague-Dawley; Rotator Cuff; Rotator Cuff Injuries; Tendons; cytokine; metformin; animal; male; rat; rotator cuff; rotator cuff injury; Sprague Dawley rat; tendon | English | 2023 | 2023-09-12 | 10.1186/s13018-023-04163-z | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Performance of Cardiovascular Risk Prediction Models in Korean Patients With New-Onset Rheumatoid Arthritis: National Cohort Study | BackgroundThis study aimed to compare the performance of established cardiovascular risk algorithms in Korean patients with new-onset rheumatoid arthritis.Methods and ResultsThis retrospective cohort study identified patients newly diagnosed with rheumatoid arthritis without a history of cardiovascular diseases between 2013 and 2019 using the National Health Insurance Service database. The cohort was followed up until 2020 for the development of the first major adverse cardiovascular event. General cardiovascular risk prediction algorithms, such as the systematic coronary risk evaluation model, the Korean risk prediction model for atherosclerotic cardiovascular diseases, the American College of Cardiology/American Heart Association pooled equations, and the Framingham Risk Score, were used. The discrimination and calibration of cardiovascular risk prediction models were evaluated. Hazard ratios were estimated using Cox proportional hazards regression. A total of 611 patients among 24 889 patients experienced a major adverse cardiovascular event during follow-up. The median 10-year atherosclerotic cardiovascular diseases risk score was significantly higher in patients with major adverse cardiovascular events than those without. The C-statistics of risk algorithms ranged between 0.72 and 0.74. Compared with the low-risk group, the actual risk of developing major adverse cardiovascular events increased significantly in the intermediate- and high-risk groups for all algorithms. However, the risk predictions calculated from all algorithms overestimated the observed cardiovascular risk in the middle to high deciles, and only the systematic coronary risk evaluation algorithm showed comparable observed and predicted event rates in the low-intermediate deciles with the highest sensitivity.ConclusionsThe systematic coronary risk evaluation model algorithm and the general risk prediction models discriminated patients with rheumatoid arthritis appropriately. However, overestimation should be considered when applying the cardiovascular risk prediction model in Korean patients. | Kim, Jae Hyun; Lee, Gaeun; Hwang, Jinseub; Kim, Ji-Won; Kwon, Jin-Won; Song, Yun-Kyoung | Jeonbuk Natl Univ, Sch Pharm, Jeonju, South Korea; Jeonbuk Natl Univ, Inst New Drug Dev, Jeonju, South Korea; Daegu Univ, Dept Stat, Gyeongbuk, South Korea; Daegu Catholic Univ, Dept Internal Med, Div Rheumatol, Sch Med, Daegu, South Korea; Kyungpook Natl Univ, Coll Pharm, FOUR Community Based Intelligent Novel Drug Discov, Daegu, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu, South Korea; Daegu Catholic Univ, Coll Pharm, 13-13 Hayang Ro, Gyongsan 38430, Gyeongbuk, South Korea | Bin Kim, Hong/J-5452-2012; Kim, Ju-Hyoung/N-1450-2019 | 57193420203; 58692232500; 57189231296; 57251295000; 16202951700; 56136407200 | yksong@cu.ac.kr; | JOURNAL OF THE AMERICAN HEART ASSOCIATION | J AM HEART ASSOC | 2047-9980 | 12 | 22 | SCIE | CARDIAC & CARDIOVASCULAR SYSTEMS | 2023 | 5 | 17.3 | 0.19 | 2025-06-25 | 0 | 1 | cardiovascular risk prediction; Korean; major adverse cardiovascular events; rheumatoid arthritis | CORONARY-ARTERY; DISEASE; SCORE; VALIDATION; PREVENTION; EVENTS; CARE | cardiovascular risk prediction; Korean; major adverse cardiovascular events; rheumatoid arthritis | Adult; Aged; Algorithms; Arthritis, Rheumatoid; Cardiovascular Diseases; Databases, Factual; Female; Heart Disease Risk Factors; Humans; Male; Middle Aged; Prognosis; Republic of Korea; Retrospective Studies; Risk Assessment; Risk Factors; adult; aged; Article; calibration; cardiovascular disease; cardiovascular risk; cohort analysis; controlled study; coronary atherosclerosis; disease risk assessment; female; follow up; Framingham risk score; human; Korean (people); major clinical study; male; medical society; national health insurance; prediction; retrospective study; rheumatoid arthritis; risk algorithm; algorithm; cardiovascular disease; complication; diagnosis; epidemiology; factual database; heart disease risk factor; middle aged; procedures; prognosis; risk assessment; risk factor; South Korea | English | 2023 | 2023-11-21 | 10.1161/jaha.123.030604 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | RadioAstron Space VLBI Imaging of the Jet in M87. I. Detection of High Brightness Temperature at 22 GHz | We present results from the first 22 GHz space very long baseline interferometric (VLBI) imaging observations of M87 by RadioAstron. As a part of the Nearby AGN Key Science Program, the source was observed in 2014 February at 22 GHz with 21 ground stations, reaching projected (u, v) spacings up to similar to 11 G.. The imaging experiment was complemented by snapshot RadioAstron data of M87 obtained during 2013-2016 from the AGN Survey Key Science Program. Their longest baselines extend up to similar to 25 G.. For all of these measurements, fringes are detected only up to similar to 2.8 Earth diameter or similar to 3G. baseline lengths, resulting in a new image with angular resolution of similar to 150 mu as or similar to 20 Schwarzschild radii spatial resolution. The new image not only shows edgebrightened jet and counterjet structures down to submilliarcsecond scales but also clearly resolves the VLBI core region. While the overall size of the core is comparable to those reported in the literature, the ground-space fringe detection and slightly superresolved RadioAstron image suggest the presence of substructures in the nucleus, whose minimum brightness temperature exceeds TB, min 10 similar to 12 K. It is challenging to explain the origin of this record-high TB, min value for M87 by pure Doppler boosting effect with a simple conical jet geometry and known jet speed. Therefore, this can be evidence for more extreme Doppler boosting due to a blazar-like small jet viewing angle or highly efficient particle acceleration processes occurring already at the base of the outflow. | Kim, Jae-Young; Savolainen, Tuomas; Voitsik, Petr; Kravchenko, Evgeniya V.

| ○ | ○ | Article | Serum Acylcarnitine and Long-Term Functional Prognosis after Traumatic Brain Injury with Intracranial Injury: A Multi-Center Prospective Study | Serum biomarkers have potential to help predict prognosis of traumatic brain injury (TBI). The objective of this study was to evaluate the association between serum acylcarnitine levels and functional outcomes at 1 month/6 months after injury for TBI patients with intracranial hemorrhage or diffuse axonal injury. This study is a multi-center prospective cohort study in which adult TBI patients with intracranial injury visiting the emergency departments (EDs) from December 2018 to June 2020 were enrolled. Serum acylcarnitine levels at the time of ED arrival were categorized into four groups: low (1.2-5.5 mu mol/L), low-normal (5.6-10.0 mu mol/L), high-normal (10.1-14.5 mu mol/L), and high (1.4.6-56.6 mu mol/L). The study outcome was set as poor functional recovery at 1 month/6 months after injury (Glasgow Outcome Scale score, 1-3). Multi-level logistic regression analyses were conducted to estimate association between serum acylcarnitine and functional outcomes. Among total of 549 patients, poor functional recovery at 1 month and 6 months after injury were observed in 29.1% (160/549) and 29.1% (158/543, follow-up loss n = 6). The odds for 1-month poor functional outcome increased in the high-normal and the high groups [adjusted odds ratios, AORs (95% confidence intervals, CIs): 1.56 (1.09-2.23) and 2.47 (1.63-3.75)], compared with the low-normal group) and also as a continuous variable [1.05 (1.03-1.07) for each 1 mu mol/L]. Regarding 6-month mortality, the high group had significantly higher odds when compared with the low-normal group [AOR (95% CI): 2.16 (1.37-3.40)]. Higher serum acylcarnitine levels are associated with poor functional outcomes at 1 month/6 months after injury for TBI patients with intracranial injury. | Lee, Stephen Gyung Won; Ro, Young Sun; Jung, Eujene; Moon, Sung Bae; Park, Gwan Jin; Yoon, Hanna; Park, Jeong Ho; Shin, Sang Do | Seoul Natl Univ, Dept Emergency Med, Boramae Med Ctr, Seoul, South Korea; Seoul Natl Univ Hosp, Lab Emergency Med Serv, Biomed Res Inst, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Emergency Med, 101 Daehak Ro, Seoul 03080, South Korea; Seoul Natl Univ, Dept Emergency Med, Coll Med, Seoul, South Korea; Chonnam Natl Univ Hosp, Dept Emergency Med, Gwangju, South Korea; Kyungpook Natl Univ, Dept Emergency Med, Sch Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Daegu, South Korea; Chungbuk Natl Univ Hosp, Dept Emergency Med, Cheongju, South Korea | Do Shin, Sang/D-6020-2012 | 57221045307; 37665990400; 57194543281; 57191584601; 57193389046; 57218530108; 57222635486; 57049712400 | ro.youngsun@gmail.com; | JOURNAL OF NEUROTRAUMA | J NEUROTRAUM | 0897-7151 | 1557-9042 | 40 | 3-4 | SCIE | CLINICAL NEUROLOGY;CRITICAL CARE MEDICINE;NEUROSCIENCES | 2023 | 3.9 | 17.3 | 0.76 | 2025-06-25 | 5 | 5 | acylcarnitine; prognosis; traumatic brain injury | CARNITINE; BIOMARKERS; IMPROVE; S100B | acylcarnitine; prognosis; traumatic brain injury | Adult; Brain Injuries; Brain Injuries, Traumatic; Glasgow Coma Scale; Humans; Prognosis; Prospective Studies; acylcarnitine; acylcarnitine; adult; aged; Article; body mass; brain function; brain injury; cohort analysis; computer assisted tomography; consciousness; controlled study; emergency ward; female; Glasgow outcome scale; human; injury scale; liquid chromatography-mass spectrometry; logistic regression analysis; long term care; major clinical study; male; multicenter study; nuclear magnetic resonance imaging; outcome assessment; prognosis; prospective study; Rankin scale; sensitivity analysis; traumatic brain injury; clinical trial; complication; Glasgow coma scale; prognosis; traumatic brain injury | English | 2023 | 2023-02-01 | 10.1089/neu.2022.0096 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
