| ○ | ○ | Article | 4′-Hydroxydehydrokawain Mitigate the Cytotoxicity of Citrinin in Porcine Intestinal Epithelial Cells | Citrinin (CTN) is a mycotoxin that adversely affects livestock by contaminating stored grains, leading to significant health and economic impacts. This study investigates the toxicological effects of CTN on porcine small intestinal epithelial cells (IPEC-J2) and explores potential mitigation strategies using natural products and chemical inhibitors. Our study demonstrates that CTN induces cytotoxicity through the TGF-beta signaling pathway, triggering apoptosis and G2/M phase cell cycle arrest. We examined cell viability, cell cycle progression, and gene expression changes in IPEC-J2 cells treated with CTN, 4 '-Hydroxydehydrokawain (4-HDK), and LY-364947, a TGF-beta receptor inhibitor. LY-364947 treatment confirmed that CTN-induced toxicity is mediated through TGF-beta signaling. Although 4-HDK alleviated CTN-induced cytotoxicity by improving cell viability and reducing apoptosis, its direct involvement in TGF-beta inhibition remains unclear. These results suggest that CTN disrupts intestinal epithelial cell homeostasis via TGF-beta activation, whereas 4-HDK may exert protective effects through an alternative mechanism. Our study provides novel insights into CTN-induced toxicity mechanisms and highlights the therapeutic potential of 4-HDK as a mitigator of mycotoxin-induced cellular damage. | Lim, Seung Joon; Shin, Sangsu; Lee, Sang In | Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea; Kyungpook Natl Univ, Res Inst Innovat Anim Sci, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea | 59759385500; 55490360000; 57203597336 | coocu1214@knu.ac.kr; sss@knu.ac.kr; silee78@knu.ac.kr; | TOXICS | TOXICS | 2305-6304 | 13 | 4 | SCIE | ENVIRONMENTAL SCIENCES;TOXICOLOGY | 2024 | 4.1 | 21.2 | 0 | 2025-05-07 | 0 | 0 | citrinin; cell cycle arrest; apoptosis; TGF-beta signaling; 4 '-hydroxydehydrokawain; IPEC-J2 cells | CYCLE ARREST; REGENERATION; MYCOTOXINS; EXPRESSION; STRESS; DEATH; B-1 | 4′-hydroxydehydrokawain; apoptosis; cell cycle arrest; citrinin; IPEC-J2 cells; TGF-beta signaling | citrinin; plant extract; transforming growth factor beta; animal cell; apoptosis; Article; cell cycle progression; cell viability; controlled study; cytotoxicity; G2 phase cell cycle checkpoint; gene expression; homeostasis; intestine epithelium cell; IPEC-J2 cell line; M phase cell cycle checkpoint; nonhuman; TGF beta signaling | English | 2025 | 2025-04-18 | 10.3390/toxics13040315 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Analysis of Fire Resistance Performance of Double Swing Fire Doors Using Thermo-Mechanical Model Depending on Gap Size | Fire doors are installed between compartments to prevent the spread of fire. During a fire, the temperature difference between the exposed and unexposed surfaces induces bending deformation of the door, thereby reducing its fire resistance performance. Excessive deformation may further compromise the structural integrity of the door. This study presents a thermo-mechanical model that idealizes the bending behavior of double swing fire doors based on the deflection equation of a simply supported beam subjected to a thermal gradient between the tensile and compressive sides. A criterion of deformation, quantifying the relationship between the meeting stile gap and the resulting maximum deflection, is introduced and compared with the predicted values. The validity of the proposed model was confirmed through fire resistance tests conducted on both insulated and non-insulated fire door specimens, demonstrating strong agreement with experimental results. Furthermore, by comparing the predicted deformation with the deformation criterion, the impact of increasing gap sizes on the service life of fire doors on their fire resistance performance was evaluated. Based on this analysis, appropriate gap size limits for different door specifications are proposed to ensure reliable fire performance. | Lim, Bohyuk; Bae, Bongki; Jang, Mingyu; Lee, Heedu; Lee, Changjun; Kim, Minkoo; Yi, Changyong | AMI Inc, Fire Lab, Jincheon Gun 27870, South Korea; Pukyong Natl Univ, Dept Fire Protect Engn, Busan 48513, South Korea; Chungbuk Natl Univ, Dept Architectural Engn, Cheongju 28644, South Korea; Kyungpook Natl Univ, Intelligent Construction Automat Ctr, Daegu 41566, South Korea | 59724688100; 59964103800; 59962750100; 53865180300; 59962750200; 57219442864; 36614886300 | bhlim@ami20.re.kr; bkbae@ami20.re.kr; mgjang@ami20.re.kr; hdlee@pknu.ac.kr; cjlee@chungbuk.ac.kr; joekim@chungbuk.ac.kr; cyyi@knu.ac.kr; | FIRE-SWITZERLAND | FIRE-BASEL | 2571-6255 | 8 | 6 | SCIE | ECOLOGY;FORESTRY | 2024 | 2.7 | 21.2 | 0 | 0 | fire doors; double swing doors; fire resistance; thermo-mechanical model; gap size | double swing doors; fire doors; fire resistance; gap size; thermo-mechanical model | English | 2025 | 2025-06-19 | 10.3390/fire8060238 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||||
| ○ | ○ | Review | Amino acids in cancer: Understanding metabolic plasticity and divergence for better therapeutic approaches | Metabolic reprogramming is a hallmark of malignant transformation. While initial studies in the field of cancer metabolism focused on central carbon metabolism, the field has expanded to metabolism beyond glucose and glutamine and uncovered the important role of amino acids in tumorigenesis and tumor immunity as energy sources, signaling molecules, and precursors for (epi)genetic modification. As a result of the development and application of new technologies, a multifaceted picture has emerged, showing that context-dependent heterogeneity in amino acid metabolism exists between tumors and even within distinct regions of solid tumors. Understanding the complexity and flexibility of amino acid metabolism in cancer is critical because it can influence therapeutic responses and predict clinical outcomes. This overview discusses the current findings on the heterogeneity in amino acid metabolism in cancer and how understanding the metabolic diversity of amino acids can be translated into more clinically relevant therapeutic interventions. | Do, Linda K.; Lee, Hyun Min; Ha, Yun-Sok; Lee, Chan-Hyeong; Kim, Jiyeon | Yale Sch Med, Dept Urol, New Haven, CT 06519 USA; Yale Sch Med, Dept Cellular & Mol Physiol, New Haven, CT 06519 USA; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Urol, Daegu 41404, South Korea | 59722836500; 57218618865; 35487226400; 59722836600; 57207437004 | jiyeon.kim1@yale.edu; | CELL REPORTS | CELL REP | 2211-1247 | 44 | 4 | SCIE | CELL BIOLOGY | 2024 | 6.9 | 21.3 | 0 | 2025-05-07 | 1 | 1 | GLUTAMINE; ASPARAGINE; ASPARTATE; SERINE; CELLS; PROGRESSION; ACTIVATION; SCREENS; CHAIN | amino acids; cancer metabolism; CP: Cancer; CP: Metabolism; metabolic heterogeneity | Amino Acids; Animals; Glutamine; Humans; Neoplasms; amino acid; glucose; glutamine; amino acid metabolism; carbon metabolism; carcinogenesis; drug therapy; energy resource; genetic modification; human; major clinical study; malignant neoplasm; malignant transformation; metabolic reprogramming; neoplastic cell transformation; review; signal transduction; solid tumor; tumor immunity; tumor metabolism; animal; metabolism; neoplasm; pathology; therapy | English | 2025 | 2025-04-22 | 10.1016/j.celrep.2025.115529 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | The ventral CA2 region of the hippocampus and its differential contributions to social memory and social aggression | The dorsal and ventral regions of the CA1 field of the hippocampus play distinct roles in the encoding of cognitive vs. emotional behaviors, respectively. Whether this distinction applies to other hippocampal fields and other behaviors is unclear. Here, we focus on the hippocampal CA2 field and compare the properties and behavioral roles of its dorsal (dCA2) and ventral (vCA2) regions. Although dCA2 is known to be required for social memory and to promote social aggression, the role of vCA2 is unknown. We report that a defined CA2 region extends to the extreme ventral pole of the hippocampus, with certain distinctions to dCA2. Unlike dCA2, chemogenetic silencing of vCA2 pyramidal neurons did not impair social memory. Similar to dCA2, vCA2 was required to promote social aggression. Thus, consistent with the CA1 region, CA2 may be differentially tuned to support cognitive compared with emotional processes along its dorsal to ventral axis. | Boyle, Lara M.; Sheng, Wanhui; Villegas, Andres; Sahai, Rhea; Irfan, Sarah; Lee, Heon-Jin; Young, W.

| ○ | ○ | Article | Relationship Between High-Density Lipoprotein Cholesterol and Mortality in Elderly Hemodialysis Patients: Data From the Korean Society of Geriatric Nephrology Retrospective Cohort | Objectives: The association between high-density lipoprotein (HDL) cholesterol levels and mortality in elderly patients undergoing hemodialysis is not well established. Thus, this study investigated HDL levels and mortality in elderly Korean patients undergoing hemodialysis. Methods: We recruited 1860 incident hemodialysis patients aged greater than 70 years from a retrospective cohort of the Korean Society of Geriatric Nephrology. The primary outcome measure was all-cause mortality. Results: The mean age of the cohort was 77.8 years, and 1049 (56.4%) were men. When we grouped the patients into HDL cholesterol tertiles, the T1 group (HDL level 40 mg/dL. Triglyceride/HDL ratio was not significantly associated with the risk of mortality (HR per 1 log increase, 1.08; 95% confidence interval, 0.99-1.18; P = .069). Conclusions: Low HDL cholesterol levels are associated with an increased risk of mortality in elderly patients undergoing hemodialysis. However, there was no significant relationship between HDL cholesterol levels and mortality when levels were below 40 mg/ dL. Therefore, low HDL cholesterol levels may be a useful risk factor for predicting mortality in elderly patients undergoing hemodialysis. | Chu, Seung Hye; Park, Eun Hee; Lee, Haekyung; Hong, Yu Ah; Park, Woo Yeong; Cho, Jang-Hee; Sun, In O.; Hwang, Won Min; Kwon, Soon Hyo; Jeon, Jin Seok; Noh, Hyunjin; Yoo, Kyung Don; Kim, Hyoungnae | Soonchunhyang Univ, Dept Internal Med, Div Nephrol, Seoul, South Korea; Soonchunhyang Univ, Hyonam Kidney Lab, Seoul, South Korea; Univ Ulsan, Ulsan Univ Hosp, Dept Internal Med, Div Nephrol,Coll Med, Ulsan, South Korea; Catholic Univ Korea, Daejeon St Marys Hosp, Coll Med, Div Nephrol,Dept Internal Med, Daejeon, South Korea; Keimyung Univ, Dongsan Hosp, Dept Internal Med, Div Nephrol,Sch Med, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Internal Med, Div Nephrol,Sch Med, Daegu, South Korea; Presbyterian Med Ctr, Dept Internal Med, Div Nephrol, Jeonju, South Korea; Konyang Univ Hosp, Dept Internal Med, Div Nephrol, Daejeon, South Korea | ; Lee, Seung Eun/ABG-1607-2021; Park, Woo Yeong/AGK-9140-2022; Cho, Jang-hee/ABD-3534-2020 | 59195027300; 58628520900; 57202973861; 55125210000; 36344980100; 7403536291; 36994821600; 55568773500; 57204097241; 36120293400; 55790442600; 56603636300; 57191261788 | ykd9062@gmail.com; hkim@schmc.ac.kr; | JOURNAL OF RENAL NUTRITION | J RENAL NUTR | 1051-2276 | 1532-8503 | 35 | 1 | SCIE | NUTRITION & DIETETICS;UROLOGY & NEPHROLOGY | 2024 | 3.2 | 21.4 | 5.31 | 2025-05-07 | 1 | 1 | elderly; HDL cholesterol; hemodialysis; mortality | DIALYSIS; RISK; ASSOCIATION; HDL | elderly; HDL cholesterol; hemodialysis; mortality | Aged; Aged, 80 and over; Cholesterol, HDL; Cohort Studies; Female; Humans; Kidney Failure, Chronic; Male; Proportional Hazards Models; Renal Dialysis; Republic of Korea; Retrospective Studies; Risk Factors; high density lipoprotein cholesterol; aged; blood; chronic kidney failure; cohort analysis; complication; epidemiology; female; hemodialysis; human; male; mortality; proportional hazards model; retrospective study; risk factor; South Korea; therapy; very elderly | English | 2025 | 2025-01 | 10.1053/j.jrn.2024.05.003 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Unrecognized Tuberculosis: Risk Factors for Smear-Positive/Cavitary Asymptomatic Cases | Background Screening patients with asymptomatic active tuberculosis (TB) is crucial as they can transmit the disease. Identifying the risk factors for transmission is essential for targeted screening. Understanding how the infectiousness of asymptomatic patients with TB affects disease outcomes is crucial for developing strategies to control TB spread. Methods We analyzed the national Korean TB cohort data to determine the factors associated with transmission risk and clinical outcomes in patients with asymptomatic pulmonary TB. The primary outcome was the factors associated with a risk factor for transmission, while the secondary outcome was mortality in asymptomatic patients with pulmonary TB stratified by transmission risk. Results Among 20 455 patients with pulmonary TB, 7434 (36.4%) were asymptomatic, while 1520 (25.5%) had potential transmission risks, indicated by a positive sputum acid-fast bacillus smear test or cavitation on chest radiographs. The factors associated with a higher transmission risk included male sex (odds ratio [OR], 1.385; 95% CI, 1.172-1.636; P < .001), low body mass index (BMI; OR, 1.687; 95% CI, 1.420-2.004; P < .001), current smoking (OR, 1.443; 95% CI, 1.213-1.716; P < .001), diabetes (OR, 1.399; 95% CI, 1.201-1.629; P < .001), and autoimmune disease (OR, 2.233; 95% CI, 1.295-3.850; P = .004). The mortality rate was higher in patients with a risk factor for transmission risk than in those without (9.3 vs 7.1%; P = .008). Conclusions Lean, smoking men with asymptomatic TB who have DM and/or autoimmune diseases have higher transmission and mortality risk. Asymptomatic populations with these risk factors warrant targeted screening. | Oh, Jee Youn; Rodwell, Timothy C.; Syed, Rehan R.; Ko, Yousang; Min, Jinsoo; Kim, Hyung Woo; Koo, Hyeon-Kyoung; Jeong, Yun-Jeong; Lee, Eun Hye; Yang, Bumhee; Chae, Ganghee; Kim, Ju Sang; Lee, Sung-Soon; Hwang, Hun-Gyu; Lee, Jaehee; Lee, Heung Bum; Na, Juock; Park, Jae Seuk | Korea Univ, Guro Hosp, Dept Internal Med, Div Pulm Allergy & Crit Care Med ,Coll Med, Seoul, South Korea; Univ Calif San Diego, Div Pulm Crit Care Sleep Med & Physiol, La Jolla, CA USA; Univ Calif San Diego, Div Infect Dis & Global Publ Hlth, La Jolla, CA USA; Hallym Univ, Kangdong Sacred Heart Hosp, Dept Internal Med, Div Pulm Allergy & Crit Care Med, Seoul, South Korea; Catholic Univ Korea, Seoul St Marys Hosp, Div Pulm & Crit Care Med, Dept Internal Med,Coll Med, Seoul, South Korea; Catholic Univ Korea, Incheon St Marys Hosp, Div Pulm & Crit Care Med, Dept Internal Med,Coll Med, Incheon, South Korea; Inje Univ, Ilsan Paik Hosp, Div Pulm & Crit Care Med, Dept Internal Med,Coll Med, Ilsan, South Korea; Dongguk Univ, Ilsan Hosp, Dept Internal Med, Div Pulm & Crit Care Med, Ilsan, South Korea; Yonsei Univ, Yongin Severance Hosp, Dept Internal Med, Div Pulmonol Allergy & Crit Care Med,Coll Med, Yongin, South Korea; Chungbuk Natl Univ, Coll Med, Div Pulm & Crit Care Med, Dept Internal Med,Chungbuk Natl Univ Hosp, Cheongju, South Korea; Univ Ulsan, Ulsan Univ Hosp, Dept Internal Med, Div Pulmonol & Crit Care Med,Coll Med, Ulsan, South Korea; Soonchunhyang Univ, Sch Med, Gumi Hosp, Dept Internal Med,Resp Div, Gumi, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Jeonbuk Natl Univ, Med Sch, Dept Internal Med, Jeonju, South Korea; Soonchunhyang Univ, Cheonan Hosp, Dept Internal Med, Div Pulm & Crit Care Med,Coll Med, Cheonan, South Korea; Dankook Univ, Coll Med, Dept Internal Med, Div Pulm Med, Cheonan, South Korea | Syed, Rehan/LRC-6424-2024; Chae, Ganghee/AAZ-8736-2021; Min, Jinsoo/D-5181-2018 | 54420734100; 6603200869; 57266415700; 55353881500; 39863339000; 59749673900; 36622978100; 55432432400; 57204439746; 57191708107; 57221348865; 56563350500; 35278414600; 55653757700; 13805476000; 35248585800; 59078093700; 15036124600 | trodwell@health.ucsd.edu; jspark@dankook.ac.kr; | OPEN FORUM INFECTIOUS DISEASES | OPEN FORUM INFECT DI | 2328-8957 | 12 | 4 | SCIE | IMMUNOLOGY;INFECTIOUS DISEASES;MICROBIOLOGY | 2024 | 3.8 | 21.5 | 0 | 2025-05-07 | 0 | 0 | asymptomatic; cohort studies; pulmonary; transmission; tuberculosis | PATIENTS INCREASES; TRANSMISSION; INFECTION; SMOKING; TIME; TB | asymptomatic; cohort studies; pulmonary; transmission; tuberculosis | alcohol consumption; Article; asymptomatic disease; autoimmune disease; body mass; cavitary asymptomatic; clinical outcome; cohort analysis; cross-sectional study; human; major clinical study; male; mortality rate; observational study; questionnaire; risk factor; screening; thorax radiography; treatment outcome; tuberculosis | English | 2025 | 2025-04 | 10.1093/ofid/ofaf176 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | Article | Optimization of a 5-Bar Linkage Mechanism Knee Prosthesis for Lower-Limb Amputees | People with amputations cannot walk because a part of their body has been amputated due to an accident or disease. They use assistive devices, such as knee prostheses, to walk. There are two types of prostheses: monocentric and polycentric. The latter has been developed to increase walking stance stability and match swing to that of normal people’s gait. A typical example of a polycentric-type knee prosthesis is a 4-bar linkage mechanism prosthesis. In this study, a 5-bar linkage prosthesis was developed to increase walking stability. A hydraulic damper, which helped the amputees swing their leg according to their walking speed, was combined with the 5-bar linkage mechanism knee prosthesis. A hydraulic damper and a brushless DC motor were combined to actively adjust the damping coefficient of the hydraulic damper. Through optimization work, the instantaneous center of rotation was designed to be relatively higher than that of the prosthetic leg with a 4-bar linkage mechanism so that it had a higher walking stability in the stance phase. Mechanical and walking experiments were conducted to evaluate the performance of the developed knee prosthesis. The mechanical performance was evaluated through movement, durability, and torque experiments. In the walking experiment, subjects wore the developed knee prosthesis and walked on a treadmill. The results confirmed that the locked state was maintained in the stance phase; thus, there was no change in the knee angle, and walking stability was improved. Furthermore, in the swing phase, the walking pattern was almost identical to that of normal people. © The Author(s), under exclusive licence to Korean Society for Precision Engineering 2025. | Lee, Ji-Woon; Ahn, Dong-Young; Lee, Won-Jae; Yi, Hak; Kim, Ki-Young | School of Mechanical Engineering, Kyungpook National University, 80 Daehak-Ro, Buk-Gu, Daegu, 41566, South Korea, Department of Medical Robot, Korea Institute of Machinery and Materials, 330, Techno Sunhwan-Ro, Yuga-Eup, Dalseong-Gun, Daegu, 42994, South Korea; Department of Prosthesis and Orthotics Center, Verterans Health Service Hospital, 53, Jinhwangdo-Ro 61-Gil, Gangdong-Gu, Seoul, 05368, South Korea; Department of Physical Medicine and Rehabilitation Center, Verterans Health Service Hospital, 53, Jinhwangdo-Ro 61-Gil, Gangdong-Gu, Seoul, 05368, South Korea; School of Mechanical Engineering, Kyungpook National University, 80 Daehak-Ro, Buk-Gu, Daegu, 41566, South Korea; Department of Medical Robot, Korea Institute of Machinery and Materials, 330, Techno Sunhwan-Ro, Yuga-Eup, Dalseong-Gun, Daegu, 42994, South Korea | 59946208900; 57200987897; 59947306200; 56567311000; 57201688619 | yihaK@knu.ac.kr; kiyoung@kimm.re.kr; | International Journal of Precision Engineering and Manufacturing | INT J PRECIS ENG MAN | 2234-7593 | 2005-4602 | SCIE | ENGINEERING, MANUFACTURING;ENGINEERING, MECHANICAL | 2024 | 3.6 | 21.7 | N/A | 0 | 5-bar mechanism; Amputee; Knee prosthesis; Polycentric knee | Artificial limbs; Damping; Electric motors; Exercise equipment; Gait analysis; Stability; Walking aids; 5-bar mechanisms; Amputee; Assistive devices; Bar linkages; Hydraulic damper; Linkage mechanism; Lower-limb amputees; Optimisations; Polycentric knee; Walking stability; Knee prostheses | English | Article in press | 2025 | 10.1007/s12541-025-01243-4 | 바로가기 | 바로가기 | 바로가기 | ||||||||||

| ○ | ○ | Article | Voltage Balancing for Triple-Active-Bridge Converter Using Integrated Transformer | The bipolar dc distribution has many advantages compared with the unipolar type. The triple-active-bridge (TAB) converter is a popular topology for the implementation of bipolar dc distribution due to its dual-output structure. However, the unbalanced output voltages caused by the asymmetric load condition is a big issue. This article proposes a voltage balancing integrated transformer to achieve the output voltage balancing in the TAB converter without requiring any additional balancer circuits or dedicated control schemes. In this article, the high-frequency transformer and two external inductors in the conventional TAB converter are merged into a single magnetic structure. As a result, the desired voltage balancing is automatically achieved and the power density of magnetic components in the converter can be increased. The voltage balancing performance of the proposed integrated transformer was tested with a 4-kW experimental prototype under severely unbalanced load conditions, and the imbalance of the output voltages is reduced to less than 1.6% where the conventional TAB converter shows 80% unbalanced results. In addition, the power density of magnetic components increased by 35% (7.9-10.7 kW/L) and the total loss of magnetic components is reduced by 19%. | Lee, Seunghoon; Cha, Honnyong; Lee, Dong-Choon | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Yeungnam Univ, Dept Elect Engn, Gyongsan 38541, Gyeongsangbuk D, South Korea | Lee, Dong-Choon/L-6825-2019 | 56089566700; 59810211800; 8510130400 | rldlghdh@knu.ac.kr; chahonny@knu.ac.kr; dclee@yu.ac.kr; | IEEE JOURNAL OF EMERGING AND SELECTED TOPICS IN POWER ELECTRONICS | IEEE J EM SEL TOP P | 2168-6777 | 2168-6785 | 13 | 2 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2024 | 4.9 | 21.7 | 0 | 2025-05-07 | 0 | 0 | Transformers; Windings; Inductors; Voltage control; Legged locomotion; Transformer cores; Inductance; Magnetic circuits; Air gaps; Zero voltage switching; Bipolar dc grid; integrated transformer; triple-active-bridge (TAB) converter; voltage balancing | DC-DC CONVERTER; CLL RESONANT CONVERTER; INDUCTOR; DESIGN | Bipolar dc grid; integrated transformer; triple-active-bridge (TAB) converter; voltage balancing | DC transformers; Distribution transformers; High frequency transformers; Voltage-source converters; Bipolar dc grid; Bridge converter; Dc distribution; DC grid; Integrated transformers; Load condition; Magnetic components; Output voltages; Triple-active-bridge converter; Voltage balancing; DC distribution systems | English | 2025 | 2025-04 | 10.1109/jestpe.2025.3545041 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Computed tomography-based measurements associated with rapid lung function decline in severe asthma | Background: Patients with severe asthma are susceptible to lung function decline (LFD), but biomarkers that reliably predict an accelerated LFD have not been fully recognized. Objective: To identify variables associated with previous LFD occurrences in patients with severe asthma by exploring the computed tomography (CT) imaging features within predefined LFD groups. Methods: We obtained inspiratory and expiratory CT images of 102 patients with severe asthma and derived 2 airway structural parameters (wall thickness [WT] and hydraulic diameter) and 2 parenchymal variables (functional small airway disease and emphysema). We retrospectively calculated the annual changes in forced expiratory volume in 1 second and grouped participants by their values determined. The 4-imaging metrics, along with levels of several biomarkers, were compared among the LFD groups. Results: Patients with severe asthma with enhanced LFD exhibited significantly lower WT and smaller hydraulic diameter compared with those with minimal change or slight decline in lung function, after an adjustment of smoking status. Conversely, CT-based percentages of emphysema and functional small airway disease did not significantly differ according to LFD. Furthermore, fractional exhaled nitric oxide (FeNO) level and the blood matrix metalloproteinase-9/TIMP metallopeptidase inhibitor 1 ratio were significantly higher in patients with severe asthma with enhanced LFD compared with those in the others. Conclusion: Lower WT on CT scans with increased FeNO that may represent increased airway inflammation significantly correlated with enhanced LFD in patients with severe asthma. Consequently, active management plans may help to attenuate LFD for patients with severe asthma with lower WT and high FeNO. (c) 2024 American College of Allergy, Asthma & Immunology.

| ○ | ○ | Article | Accuracy of Stellar Mass-to-light Ratios of Nearby Galaxies in the Near Infrared | Future satellite missions are expected to perform all-sky surveys, thus providing the entire sky near-infrared spectral data and consequently opening a new window to investigate the evolution of galaxies. Specifically, the infrared spectral data facilitate the precise estimation of stellar masses of numerous low-redshift galaxies. We utilize the synthetic spectral energy distribution (SED) of 2853 nearby galaxies drawn from the DustPedia (435) and Stripe 82 regions (2418). The stellar mass-to-light ratio (M*/L) estimation accuracy over a wavelength range of 0.75-5.0 mu m is computed through the SED fitting of the multiwavelength photometric data set, which has not yet been intensively explored in previous studies. We find that the scatter in M*/L is significantly larger in the shorter and longer wavelength regimes due to the effect of the young stellar population and the dust contribution, respectively. While the scatter in M*/L approaches its minimum (similar to 0.10 dex) at similar to 1.6 mu m, it remains sensitive to the adopted star formation history model. Furthermore, M*/L demonstrates weak and strong correlations with the stellar mass and the specific star formation rate (SFR), respectively. Upon adequately correcting the dependence of M*/L on the specific SFR, the scatter in the M*/L further reduces to 0.02 dex at similar to 1.6 mu m. This indicates that the stellar mass can be estimated with an accuracy of similar to 0.02 dex with a prior knowledge of SFR, which can be estimated using the infrared spectra obtained with future survey missions. | Kim, Taehyun; Kim, Minjin; Ho, Luis C.; Li, Yang A.; Jeong, Woong-Seob; Kim, Dohyeong; Kim, Yongjung; Lee, Bomee; Lee, Dongseob; Lee, Jeong Hwan; Pyo, Jeonghyun; Shim, Hyunjin; Son, Suyeon; Song, Hyunmi; Yang, Yujin | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; Peking Univ, Kavli Inst Astron & Astrophys, Beijing 100871, Peoples R China; Peking Univ, Sch Phys, Dept Astron, Beijing 100871, Peoples R China; Shanghai Jiao Tong Univ, Sch Phys & Astron, Dept Astron, Shanghai 200240, Peoples R China; Korea Astron & Space Sci Inst, Daejeon 34055, South Korea; Univ Sci & Technol Korea, Daejeon 34113, South Korea; Pusan Natl Univ, Dept Earth Sci, Busan 46241, South Korea; Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea; Seoul Natl Univ, Dept Phys & Astron, 1 Gwanak Ro, Seoul 08826, South Korea; Seoul Natl Univ, Res Inst Basic Sci, Seoul 08826, South Korea; Chungnam Natl Univ, Dept Astron & Space Sci, Daejeon 34134, South Korea | ; Kim, Minjin/AAU-9910-2020; Li, Yang/MEO-8870-2025; , Yong Jung Kim/JRW-0681-2023; Shim, Hyunjin/LZI-7486-2025 | 57050549000; 56898213300; 57225302746; 57219452188; 7102145940; 55574223678; 59622148200; 55832276300; 57218674853; 57195344163; 22036293900; 14061137700; 57226328130; 35749280400; 7409384232 | mkim.astro@gmail.com; | ASTRONOMICAL JOURNAL | ASTRON J | 0004-6256 | 1538-3881 | 169 | 1 | SCIE | ASTRONOMY & ASTROPHYSICS | 2024 | 5.1 | 22.0 | 3.15 | 2025-05-07 | 2 | 2 | AROMATIC-HYDROCARBON EMISSION; SPECTRAL ENERGY-DISTRIBUTIONS; STAR-FORMATION HISTORY; S(4)G IRAC 3.6; ASSEMBLY GAMA; FORMING GALAXIES; DUST; ULTRAVIOLET; PHOTOMETRY; EVOLUTION | English | 2025 | 2025-01-03 | 10.3847/1538-3881/ad95eb | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
