| ○ | ○ | Article | Clinical Feasibility of Dual-Layer CT With Virtual Monochromatic Image for Preoperative Staging in Patients With Breast Cancer: A Comparison With Breast MRI | Objective: Dual-layer CT (DLCT) can create virtual monochromatic images (VMIs) at various monochromatic X-ray energies, particularly at low keV levels, with high contrast-to-noise ratio. The purpose of this study was to assess the clinical feasibility of contrast-enhanced chest DLCT with a low keV VMI for preoperative breast cancer staging, in comparison to breast MRI. Materials and Methods: A total of 152 patients with 155 index breast cancers were enrolled in the study. VMIs were generated from contrast-enhanced chest DLCT at 40 keV and maximum intensity projection (MIP) with three-dimensional (3D) reconstruction was performed for both bilateral breast areas. Two radiologists reviewed in consensus the 3D MIP images of the chest DLCT with VMI and breast MRI in separate sessions with a 3-month wash-out period. The detection rate and mean tumor size of the index cancer were compared between the chest DLCT with VMI and breast MRI. Additionally, the agreement of tumor size measurement between the two imaging modalities were evaluated. Results: Of all index cancers, 84.5% (131/155) were detected in the chest DLCT with VMI, while 88.4% (137/155) were detected in the breast MRI (P = 0.210). The Bland-Altman agreement between the chest DLCT with VMI and breast MRI was a mean difference of -0.05 cm with 95% limits of agreement of -1.29 to 1.19 cm. The tumor size in the chest DLCT with VMI (2.3 +/- 1.7 cm) was not significantly different from that in the breast MRI (2.4 +/- 1.6 cm) (P = 0.106). Conclusion: The feasibility of chest DLCT with VMI was demonstrated for preoperative tumor staging in breast cancer patients, showing comparable cancer detectability and good agreement in tumor size measurement compared to breast MRI. This suggests that chest DLCT with VMI can serve as a potential alternative for patients who have contraindications to breast MRI. | Yeo, Bokdong; Shin, Kyung Min; Park, Byunggeon; Kim, Hye Jung; Kim, Won Hwa | Kyungpook Natl Univ Hosp, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Radiol, 807 Hoguk Ro, Daegu 41404, South Korea | 58712813800; 7402410737; 57211532915; 59310314100; 36081886500 | mamrad@knu.ac.kr;oaktree9@knu.ac.kr; | KOREAN JOURNAL OF RADIOLOGY | KOREAN J RADIOL | 1229-6929 | 2005-8330 | 25 | 9 | SCIE | RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2024 | 5.3 | 10.1 | 0 | 2025-05-07 | 1 | 1 | Breast cancer; Dual-layer CT; Virtual monochromatic image; Low keV; Cancer staging | ENERGY CT; SIZE | Breast cancer; Cancer staging; Dual-layer CT; Low keV; Virtual monochromatic image | Adult; Aged; Breast Neoplasms; Contrast Media; Feasibility Studies; Female; Humans; Imaging, Three-Dimensional; Magnetic Resonance Imaging; Middle Aged; Neoplasm Staging; Preoperative Care; Tomography, X-Ray Computed; gadobutrol; Ki 67 antigen; contrast medium; adult; Article; breast cancer; breast magnetic resonance imaging; cancer patient; carcinogenesis; contrast to noise ratio; diagnostic accuracy; echomammography; female; human; image reconstruction; lobular carcinoma; major clinical study; male; neoadjuvant chemotherapy; nuclear magnetic resonance imaging; pancreas islet cell tumor; radiation exposure; retrospective study; tumor volume; X ray analysis; aged; breast tumor; cancer staging; comparative study; diagnostic imaging; feasibility study; middle aged; nuclear magnetic resonance imaging; pathology; preoperative care; procedures; surgery; three-dimensional imaging; x-ray computed tomography | English | 2024 | 2024-09 | 10.3348/kjr.2023.1312 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Dendrite-suppressed Li deposition enabled by surface-tailored carbon-based current collectors for high-rate and stable Li-metal batteries | Lithium (Li) -metal batteries (LMBs) are considered as one of the most promising next -generation batteries due to the exceptionally low redox potential and high specific capacity of the Li metal anode. However, their practical application remains challenging due to problems such as Li dendrites growth and poor Coulombic efficiency (CE) during cycling. Among the various approaches proposed to solve these challenges, the introduction of 3D current collectors has been proven effective for suppressing the growth of dendritic Li. Nevertheless, the surface properties of 3D current collectors have been somewhat overlooked in existing studies. In this work, we assessed three distinct carbon nanotube (CNT)-based current collectors (namely, CNT, oxidized CNT (ONT), and reduced ONT (rONT)) to investigate the effects of their surface properties and compositions on the Li deposition process and, hence, the electrochemical stability of the resulting LMBs. The pristine CNT-based current collector exhibits a poor electrolyte wettability, thus resulting in a rapid decline in CE over successive cycles. In contrast, the ONT current collector shows enhanced electrolyte wettability with lithiophilic surface, which significantly improves the interfacial kinetics and cycling stability. Moreover, after the subsequent reduction process, the rONT current collector exhibits a higher electrical conductivity than the ONT current collector while maintaining the favorable electrolyte wettability. Consequently, the Li|rONT cell delivers a more stable cycling performance than the Li| ONT cell at high current densities. These results demonstrate that the electrochemical performances of the LMBs can be significantly improved by suitably modifying the surface characteristics of the current collectors. | Lee, Seungho; Yang, Subi; Lee, Kyunbae; Jung, Yeonsu; Choi, Junghyun; Kim, Taehoon; Kim, Patrick Joohyun | Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Korea Inst Ceram Engn & Technol, Energy Storage Mat Ctr, Jinju 52851, South Korea; Gachon Univ, Dept Battery Engn, Seongnam Si 13120, Gyeonggi Do, South Korea; Korea Inst Mat Sci KIMS, Composites Res Div, Chang Won 51508, South Korea | ; Kim, Taehoon/A-1088-2012 | 59627599900; 58817498700; 57205304948; 55195879700; 59883103900; 57449684100; 57195611779 | tkim67@kims.re.kr;pjkim@knu.ac.kr; | CARBON | CARBON | 0008-6223 | 1873-3891 | 221 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 11.6 | 10.1 | 1.92 | 2025-05-07 | 7 | 7 | Lithium metal battery; Carbon nanotube; Current collector; Surface modification | CONTAINING FUNCTIONAL-GROUPS; LITHIUM-SULFUR BATTERIES; REDUCED GRAPHENE OXIDE; SINGLE-WALL; PERFORMANCE; CATHODE; ELECTRODES; NANOTUBES; ANODES | Carbon nanotube; Current collector; Lithium metal battery; Surface modification | Deposition; Electric current collectors; Electrolytes; Lithium batteries; Redox reactions; Wetting; Carbon-based; Coulombic efficiency; Current-collector; High rate; Li metal; Lithium metal battery; Lithium metals; Redox potentials; Redoxpotential; Surface-modification; Carbon nanotubes | English | 2024 | 2024-03 | 10.1016/j.carbon.2024.118941 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Direct-spun carbon nanotube sheet: A flexible, ultralight, stackable three-dimensional current collector for high-performance lithium-ion batteries | Among the key components of a battery electrode, current collectors hold significant importance for the energy density of lithium ion batteries (LIBs) as metal foils account for a significant proportion of the total mass. Carbon nanotube sheet (CNTS) has garnered considerable attention because of its fascinating material features such as high electrical conductivity, low density, and excellent flexibility. In this study, we demonstrate the utilization of a direct-spun CNTS as a current collector in order to enhance the electrochemical performance and replace the conventional current collector, that is, aluminum (Al) foil, in LIBs. When the CNTS coated with NCM811 (NCM811/CNTS) is evaluated in LIBs, it delivers superior rate capability and cycle stability compared with Al foil-based and buckypaper-based NCM811 electrodes. It is because the CNTS with a large surface area and high electrical conductivity establishes a number of electronic pathways to the cathode electrode. In addition, the porous structure of the CNTS efficiently enhances the adhesive properties of the electrodes. Due to the synergistic benefits of CNTS, cells with stacked NCM811/CNTS electrodes are successfully fabricated. Electrode stacking with multiple NCM811/CNTS electrodes exhibits improved areal capacity and stable cycle stability, suggesting a new strategy to replace the concept of conventional thick electrodes. Moreover, pouch cells with LTO/CNTS as an anode and NCM811/CNTS as a cathode display stable electrochemical performance even under mechanical deformation (e.g., folding/unfolding) | Jo, Semin; Lee, Kyunbae; Jung, Yeonsu; Woo, Donguk; Kim, Taehoon; Kim, Patrick Joohyun | Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Korea Inst Mat Sci KIMS, Composites Res Div, Chang Won 51508, South Korea | Kim, Taehoon/A-1088-2012 | 58672375600; 57205304948; 55195879700; 58672537900; 57449684100; 57195611779 | tkim67@kims.re.kr;pjkim@knu.ac.kr; | CARBON | CARBON | 0008-6223 | 1873-3891 | 219 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 11.6 | 10.1 | 3.29 | 2025-05-07 | 14 | 13 | Carbon nanotube sheet; Current collector; Lithium ion batteries; Lightweight; Direct spinning; Thick electrode | ELECTRODES; CORROSION; BEHAVIOR; FIBERS | Carbon nanotube sheet; Current collector; Direct spinning; Lightweight; Lithium ion batteries; Thick electrode | Adhesives; Aluminum coatings; Aluminum foil; Anodes; Carbon nanotubes; Cathodes; Electric conductivity; Electric current collectors; Ions; Metal cladding; Carbon nanotube sheets; Current-collector; Cycle stability; Direct spinnings; Electrochemical performance; High electrical conductivity; High-performance lithium-ion batteries; Lightweight; Thick electrodes; Ultra-light; Lithium-ion batteries | English | 2024 | 2024-02-10 | 10.1016/j.carbon.2024.118786 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Dynamic asset allocation and consumption ratcheting with costs | This paper delves into studying the optimal decisions regarding consumption and investment for an agent operating within a finite time frame, where any reduction in consumption is intolerable. In contrast to Jeon et al. (2018), we assume that the agent incurs a proportional utility cost with each increase in consumption. To tackle this problem, we employ the duality method to define the dual problem and investigate the resulting upper obstacle problem using PDE techniques. Our study reveals the existence of a critical time attributed to the utility cost, beyond which not only does the agent cease to further increase their consumption, but they also abstain from investing in the risky asset. Furthermore, the existence of the critical time makes free boundary analysis even more challenging, as this is because the presence of the critical time can also lead to the disruption of the monotonicity of the free boundary. | Jeon, Junkee; Oh, Jehan | Kyung Hee Univ, Coll Appl Sci, Dept Appl Math, Yongin, South Korea; Kyungpook Natl Univ, Dept Math, Daegu, South Korea | 57056929900; 56673305300 | junkeejeon@khu.ac.kr;jehan.oh@knu.ac.kr; | JOURNAL OF COMPUTATIONAL AND APPLIED MATHEMATICS | J COMPUT APPL MATH | 0377-0427 | 1879-1778 | 448 | SCIE | MATHEMATICS, APPLIED | 2024 | 2.6 | 10.1 | 0 | 2025-05-07 | 0 | 0 | Consumption ratcheting; Investment; Utility cost; Obstacle problem; Free boundary problem; Singular control problem | SINGULAR STOCHASTIC-CONTROL; PORTFOLIO SELECTION; INTOLERANCE; CONNECTIONS; DECLINE; FINITE | Consumption ratcheting; Free boundary problem; Investment; Obstacle problem; Singular control problem; Utility cost | Asset allocation; Consumption ratcheting; Control problems; Critical time; Free boundary; Free-boundary problems; Obstacle problems; Singular control; Singular control problem; Utility costs; Investments | English | 2024 | 2024-10-01 | 10.1016/j.cam.2024.115966 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Exploring Unobscured Quasi-stellar Objects in the Southern Hemisphere with KS4 | We present a catalog of unobscured quasi-stellar object (QSO) candidates in the Southern Hemisphere from the early interim data of the KMTNet Synoptic Survey of Southern Sky (KS4). The KS4 data covers similar to 2500 deg(2) sky area, reaching 5 sigma detection limits of similar to 22.1-22.7 AB mag in the BVRI bands. Combining this with available infrared photometric data from the surveys covering the southern sky, we select the unobscured QSO candidates based on their colors and spectral energy distribution fitting results. The final catalog contains 72,964 unobscured QSO candidates, of which only 0.4% are previously identified as QSOs based on spectroscopic observations. Our selection method achieves an 87% recovery rate for spectroscopically confirmed bright QSOs at z < 2 within the KS4 survey area. In addition, the number count of our candidates is comparable to that of spectroscopically confirmed QSOs from the Sloan Digital Sky Survey in the northern sky. These demonstrate that our approach is effective in searching for unobscured QSOs in the southern sky. Future spectrophotometric surveys covering the southern sky will enable us to discern their true nature and enhance our understanding of QSO populations in the Southern Hemisphere. | Kim, Yongjung; Kim, Minjin; Im, Myungshin; Chang, Seo-Won; Jeong, Mankeun; Byun, Woowon; Kim, Joonho; Kim, Dohyeong; Shim, Hyunjin; Song, Hyunmi | Korea Astron & Space Sci Inst, Daejeon 34055, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; Seoul Natl Univ, SNU Astron Res Ctr, 1 Gwanak Ro, Seoul 08826, South Korea; Seoul Natl Univ, Dept Phys & Astron, Astron Program, 1 Gwanak Ro, Seoul 08826, South Korea; Daegu Natl Sci Museum, 20 Techno Daero 6 Gil, Daegu 43023, South Korea; Pusan Natl Univ, Dept Earth Sci, Pusan 46241, South Korea; Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea; Chungnam Natl Univ, Dept Astron & Space Sci, Daejeon 34134, South Korea | , Yong Jung Kim/JRW-0681-2023; Im, Myungshin/B-3436-2013; Shim, Hyunjin/LZI-7486-2025; Kim, Minjin/AAU-9910-2020 | 59622148200; 56898213300; 7004267711; 55271541100; 57209213509; 57216758314; 57219528062; 55574223678; 14061137700; 35749280400 | yjkim.ast@gmail.com;mkim.astro@gmail.com; | ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES | ASTROPHYS J SUPPL S | 0067-0049 | 1538-4365 | 275 | 2 | SCIE | ASTRONOMY & ASTROPHYSICS | 2024 | 8.5 | 10.1 | 0 | 2025-05-07 | 0 | 0 | ACTIVE GALACTIC NUCLEI; DIGITAL SKY SURVEY; BLACK-HOLE MASSES; FOLLOW-UP OBSERVATION; DARK ENERGY SURVEY; SIMILAR-TO 5; SPACE-TELESCOPE; PHOTOMETRIC REDSHIFTS; LUMINOSITY FUNCTION; OBSCURED QUASARS | English | 2024 | 2024-12-01 | 10.3847/1538-4365/ad89be | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Interpretation of Complete Tumor Response on MRI Following Chemoradiotherapy of Rectal Cancer: Inter-Reader Agreement and Associated Factors in Multi-Center Clinical Practice | Objective: To measure inter -reader agreement and identify associated factors in interpreting complete response (CR) on magnetic resonance imaging (MRI) following chemoradiotherapy (CRT) for rectal cancer. Materials and Methods: This retrospective study involved 10 readers from seven hospitals with experience of 80-10210 cases, and 149 patients who underwent surgery after CRT for rectal cancer. Using MRI-based tumor regression grading (mrTRG) and methods employed in daily practice, the readers independently assessed mrTRG, CR on T2 -weighted images (T2WI) denoted as mrCRT2W, and CR on all images including diffusion -weighted images (DWI) denoted as mrCRoverall. The readers described their interpretation patterns and how they utilized DWI. Inter -reader agreement was measured using multi -rater kappa, and associated factors were analyzed using multivariable regression. Correlation between sensitivity and specificity of each reader was analyzed using Spearman coefficient. Results: The mrCRT2W and mrCRoverall rates varied widely among the readers, ranging 18.8%-40.3% and 18.1%-34.9%, respectively. Nine readers used DWI as a supplement sequence, which modified interpretations on T2WI in 2.7% of cases (36/1341 [149 patients x 9 readers]) and mostly (33/36) changed mrCRT2W to non-mrCRoverall. The kappa values for mrTRG, mrCRT2W, and mrCRoverall were 0.56 (95% confidence interval: 0.49, 0.62), 0.55 (0.52, 0.57), and 0.54 (0.51, 0.57), respectively. No use of rectal gel, larger initial tumor size, and higher initial cT stage exhibited significant association with a higher interreader agreement for assessing mrCRoverall (P <= 0.042). Strong negative correlations were observed between the sensitivity and specificity of individual readers (coefficient, -0.718 to -0.963; P <= 0.019). Conclusion: Inter -reader agreement was moderate for assessing CR on post -CRT MRI. Readers' varying standards on MRI interpretation (i.e., threshold effect), along with the use of rectal gel, initial tumor size, and initial cT stage, were significant factors associated with inter -reader agreement. | Kim, Hae Young; Cho, Seung Hyun; Jang, Jong Keon; Kim, Bohyun; Lee, Chul-min; Lim, Joon Seok; Moon, Sung Kyoung; Oh, Soon Nam; Seo, Nieun; Park, Seong Ho | Seoul Natl Univ, Bundang Hosp, Dept Radiol, Seongnam, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Radiol, Daegu, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Radiol, 88 Olymp Rro 43 Gil, Seoul 05505, South Korea; Univ Ulsan, Res Inst Radiol, Coll Med, Asan Med Ctr, 88 Olymp Rro 43 Gil, Seoul 05505, South Korea; Catholic Univ Korea, Seoul St Marys Hosp, Coll Med, Dept Radiol, Seoul, South Korea; Hanyang Univ, Coll Med, Dept Radiol, Seoul, South Korea; Yonsei Univ, Coll Med, Severance Hosp, Dept Radiol, Seoul, South Korea; Kyung Hee Univ Hosp, Dept Radiol, Seoul, South Korea; Asan Med Ctr, Dept Radiol, Seoul, South Korea | ; Kim, Byung/L-6884-2019; Lim, Joon Seok/R-7753-2019; Park, Seong-Ho/HKV-2294-2023; Park, Seong Ho/E-2271-2014 | 57195306239; 55686242700; 49661843500; 57791012600; 57219662910; 7403453992; 35798730300; 7404104100; 54387409200; 57049729900 | parksh.radiology@gmail.com; | KOREAN JOURNAL OF RADIOLOGY | KOREAN J RADIOL | 1229-6929 | 2005-8330 | 25 | 4 | SCIE | RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2024 | 5.3 | 10.1 | 0.68 | 2025-05-07 | 1 | 1 | Magnetic resonance imaging; Rectal neoplasms; Chemoradiotherapy; Reader; Rater; Observer; Reliability; Reproducibility; Agreement; Variability; Variation | PATHOLOGICAL COMPLETE RESPONSE; REGRESSION GRADE; NEOADJUVANT TREATMENT; CHEMORADIATION; RELIABILITY; OUTCOMES; THERAPY; SOCIETY | Agreement; Chemoradiotherapy; Magnetic resonance imaging; Observer; Rater; Reader; Rectal neoplasms; Reliability; Reproducibility; Variability; Variation | Chemoradiotherapy; Diffusion Magnetic Resonance Imaging; Humans; Magnetic Resonance Imaging; Pathologic Complete Response; Rectal Neoplasms; Retrospective Studies; Sensitivity and Specificity; carcinoembryonic antigen; adolescent; adult; aged; apparent diffusion coefficient; Article; cancer staging; chemoradiotherapy; clinical practice; controlled study; correlation coefficient; disease free survival; female; gray matter; human; image analysis; male; middle aged; multicenter study; multiparametric magnetic resonance imaging; narrow band imaging; nuclear magnetic resonance imaging; pathological complete response; radiation dose; rectum cancer; retrospective study; sensitivity and specificity; tumor regression; tumor volume; chemoradiotherapy; diagnostic imaging; diffusion weighted imaging; pathology; procedures; rectum tumor | English | 2024 | 2024-04 | 10.3348/kjr.2023.1213 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Local Ablation for Hepatocellular Carcinoma: 2024 Expert Consensus-Based Practical Recommendations of the Korean Liver Cancer Association | Local ablation for hepatocellular carcinoma (HCC), a non-surgical option that directly targets and destroys tumor cells, has advanced significantly since the 1990s. Therapies with different energy sources, such as radiofrequency ablation, microwave ablation, and cryoablation, employ different mechanisms to induce tumor necrosis. The precision, safety, and effectiveness of these therapies have increased with advances in guiding technologies and device improvements. Consequently, local ablation has become the first-line treatment for early-stage HCC. The lack of organized evidence and expert opinions regarding patient selection, pre-procedure preparation, procedural methods, swift post-treatment evaluation, and follow-up has resulted in clinicians following varied practices. Therefore, an expert consensus-based practical recommendation for local ablation was developed by a group of experts in radiology and hepatology from the Research Committee of the Korean Liver Cancer Association in collaboration with the Korean Society of Image-guided Tumor Ablation to provide useful information and guidance for performing local ablation and for the pre- and post-treatment management of patients. | Han, Seungchul; Sung, Pil Soo; Park, Soo Young; Kim, Jin Woong; Hong, Hyun Pyo; Yoon, Jung-Hee; Chung, Dong Jin; Kwon, Joon Ho; Lim, Sanghyeok; Kim, Jae Hyun; Shin, Seung Kak; Kim, Tae Hyung; Lee, Dong Ho; Choi, Jong Young | Samsung Med Ctr, Dept Radiol, Seoul, South Korea; Catholic Univ Korea, Seoul St Marys Hosp, Dept Internal Med, Seoul, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Internal Med, Sch Med, Daegu, South Korea; Chosun Univ Hosp, Dept Surg, Gwangju, South Korea; Chosun Univ, Coll Med, Gwangju, South Korea; Sungkyunkwan Univ, Kangbuk Samsung Hosp, Sch Med, Dept Radiol, Seoul, South Korea; Inje Univ, Haeundae Paik Hosp, Coll Med, Dept Radiol, Busan, South Korea; Catholic Univ Korea, Yeouido St Marys Hosp, Dept Radiol, Seoul, South Korea; Yonsei Univ, Severance Hosp, Dept Radiol Res, Res Inst Radiol Sci,Inst Radiol Sci,Coll Med, Seoul, South Korea; Soonchunhyang Univ, Coll Med, Hosp Bucheon, Dept Radiol, Bucheon, South Korea; Seoul Natl Univ, Seoul Natl Univ Hosp, Bundang Hosp, Seoul 03080, South Korea; Gachon Univ, Coll Med, Gil Med Ctr, Dept Internal Med, Incheon, South Korea; Hallym Univ, Sacred Heart Hosp, Dept Internal Med, Anyang, South Korea | Kim, Tae/AAL-8552-2021; Sung, Pil Soo/AAD-6344-2021 | 57205345915; 57206341074; 57191674344; 57196169638; 22834834700; 55705048800; 7401719231; 55206691900; 55842755400; 57211596138; 57219944778; 57755913500; 57222878418; 57203732617 | dhlee.rad@gmail.com; | KOREAN JOURNAL OF RADIOLOGY | KOREAN J RADIOL | 1229-6929 | 2005-8330 | 25 | 9 | SCIE | RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2024 | 5.3 | 10.1 | 0.68 | 2025-05-07 | 1 | 1 | Hepatocellular carcinoma; Hepatoma; Liver cancer; Local ablation; Practical recommendation; Guideline; Guidance | PERCUTANEOUS RADIOFREQUENCY ABLATION; RANDOMIZED CONTROLLED-TRIAL; CONTRAST-ENHANCED ULTRASONOGRAPHY; ANTIBIOTIC-PROPHYLAXIS; POOR CONSPICUOUSNESS; THERMAL ABLATION; HEPATIC-TUMORS; CRYOABLATION; COMPLICATIONS; MANAGEMENT | Guidance; Guideline; Hepatocellular carcinoma; Hepatoma; Liver cancer; Local ablation; Practical recommendation | Ablation Techniques; Carcinoma, Hepatocellular; Catheter Ablation; Consensus; Humans; Liver Neoplasms; Patient Selection; Republic of Korea; antibiotic agent; cefotaxime; ceftriaxone; cephalosporin; contrast medium; corticosteroid; fresh frozen plasma; metoclopramide; morphine; nonsteroid antiinflammatory agent; opiate; tramadol; ablation therapy; Aeromonas hydrophila; arthroscopy; Article; bacteremia; bleeding; bleeding tendency; bradycardia; chemoembolization; choledochojejunostomy; Clostridium perfringens; computer assisted tomography; consensus; coughing; cryoablation; echography; electrocardiography; endoscopic retrograde cholangiopancreatography; endoscopic sphincterotomy; endoscopic submucosal dissection; evaluation and follow up; fever; first-line treatment; fluoroscopy; follow up; hospitalization; human; hypothermia; Klebsiella pneumoniae; liver abscess; liver cancer; liver cell carcinoma; liver cirrhosis; liver metastasis; mechanical thrombectomy; microwave radiation; microwave thermotherapy; nuclear magnetic resonance imaging; oxygen saturation; patient selection; platelet count; pleura effusion; pneumothorax; practice guideline; prothrombin time; pulse rate; radiofrequency ablation; risk factor; sphincterotomy; Staphylococcus aureus; survival rate; thrombocytopenia; tumor ablation; tumor growth; tumor necrosis; tumor volume; ablation therapy; catheter ablation; diagnostic imaging; liver tumor; pathology; procedures; South Korea; surgery | English | 2024 | 2024-09 | 10.3348/kjr.2024.0550 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Mussel byssus-inspired gallol-enriched chitosan hydrogel fibers with strong adhesive properties | The byssus of marine mussels, which exhibits a strong adhesion to rocks in seawater, is an important target for biomimetics. The underwater adhesion of the byssus to rocks relies on mussel foot proteins (Mfps), which contain 3,4-dihydroxyphenyl-L-alanine with a catechol group and lysine with an amino group that act cooperatively. In this study, Mfps-inspired hydrogel fibers were designed by combining a gallol group with chitosan. A chitosan-gallic acid (CS-GA) conjugate was synthesized by grafting GA onto CS, and CS-GA hydrogel fibers were prepared by simple needle spinning of a concentrated CS-GA solution into a neutral or weakly basic buffer solution. Furthermore, the self-crosslinking mechanism, swelling and self-healing behaviors, adhesive properties, and tensile properties of the CS-GA gel fibers were investigated according to the solution pH. The Schiff base (reversible covalent bonding) and Michael addition (irreversible covalent bonding) reactions were dominant at pH 7.4 and 8.5, respectively. Moreover, the CS-GA hydrogel fibers exhibited high adhesive strength under wet conditions owing to the residual amino groups. The tensile strength of the fibers formed in a coagulation bath with a Fe3+-added buffer was augmented owing to the formation of metal coordination bonds. The biomimetic CS-GA hydrogel fibers have great prospects for various applications. | Gwak, Min A.; Choi, Yun Hyeok; Kim, Min Hee; Park, Won Ho | Chungnam Natl Univ, Dept Organ Mat Engn, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Text Engn, Sangju, South Korea; Chungnam Natl Univ, Coll Engn, Dept Organ Mat Engn, Daejeon 34134, South Korea | 57225067013; 58786181500; 57223215235; 57211114215 | mhkim88@knu.ac.kr;parkwh@cnu.ac.kr; | EUROPEAN POLYMER JOURNAL | EUR POLYM J | 0014-3057 | 1873-1945 | 204 | SCIE | POLYMER SCIENCE | 2024 | 6.3 | 10.1 | 1.5 | 2025-05-07 | 9 | 9 | Chitosan; Gallol; Self-crosslinking; Mussel-inspired; Organohydrogel | SURFACE-ADHESION; ACID; COHESION; PERFORMANCE; CELLULOSE | Chitosan; Gallol; Mussel-inspired; Organohydrogel; Self-crosslinking | Addition reactions; Adhesion; Adhesives; Amino acids; Biomimetics; Fiber bonding; Fibers; Hydrogels; Molluscs; Spinning (fibers); Tensile strength; Adhesive properties; Amino group; Covalent bonding; Gallic acids; Gallol; Hydrogel fibers; Mussel byssus; Mussel-inspired; Organohydrogel; Self-crosslinking; Chitosan | English | 2024 | 2024-01-24 | 10.1016/j.eurpolymj.2023.112673 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Predictive factors for severe radiation-induced lung injury in patients with lung cancer and coexisting interstitial lung disease | Background and purpose: This study aimed to investigate the predictive factors of severe radiation-induced lung injury (RILI) in patients with lung cancer and coexisting interstitial lung disease (ILD) undergoing conventionally fractionated thoracic radiotherapy. Materials and methods: The study includes consecutive patients treated with thoracic radiotherapy for lung cancer at two tertiary centers between 2010 and 2021. RILI severity was graded using the National Cancer Institute Common Terminology Criteria version 5.0, with severe RILI defined as toxicity grade >= 4, and symptomatic RILI as grade >= 2. The absolute neutrophil count (ANC), absolute lymphocyte count (ALC), and C-reactive protein were collected within 4 weeks before starting radiotherapy. Neutrophil-lymphocyte ratios (NLR) were calculated as ANC/ALC. The median follow-up was 9 (range, 6-114) months. Results: Among 54 patients, 22 (40.7 %) had severe RILI. On multivariate logistic regression analysis, high pretreatment ANC (p = 0.030, OR = 4.313), pretreatment NLR (p = 0.007, OR = 5.784), and ILD severity (p = 0.027, OR = 2.416) were significant predictors of severe RILI. Dosimetric factors were not associated with severe RP. Overall survival was significantly worse for patients with severe RILI than those without, with 1-year cumulative overall survival rates of 7.4 % and 62.8 %, respectively. Conclusion: Pretreatment blood NLR, ANC, and ILD severity were associated with severe RILI. Overall survival was dismal for patients with severe RILI. | Park, Shin-Hyung; Lim, Jae-Kwang; Kang, Min Kyu; Park, Jongmoo; Hong, Chae Moon; Kim, Chang Ho; Cha, Seung Ick; Lee, Jaehee; Lee, Seoung-Jun; Kim, Jae-Chul | Kyungpook Natl Univ, Sch Med, Dept Radiat Oncol, Daegu, South Korea; Kyungpook Natl Univ, Cardiovasc Res Inst, Sch Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Nucl Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Radiat Oncol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiat Oncol, 130 Dongduk Ro, Daegu 41944, South Korea | ; Park, Shinhyung/LNQ-6428-2024; Lee, Yoojin/AAB-9799-2022; Lee, Jaehee/S-1697-2018 | 57203275843; 55515341400; 57201933342; 56180048900; 37050876700; 7409873555; 35227126400; 13805476000; 57204661287; 55719981700 | shinhyungpark@knu.ac.kr; | RADIOTHERAPY AND ONCOLOGY | RADIOTHER ONCOL | 0167-8140 | 1879-0887 | 192 | SCIE | ONCOLOGY;RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2024 | 5.3 | 10.1 | 3.04 | 2025-05-07 | 8 | 7 | Lung neoplasms; Lung disease; interstitial; Radiation pneumonitis; Radiotherapy; Biomarkers; Neutrophils; Lymphocytes | IDIOPATHIC PULMONARY-FIBROSIS; ORGANIZING PNEUMONIA SYNDROME; BREAST-CONSERVING THERAPY; ACUTE EXACERBATION | Biomarkers; Lung disease, interstitial; Lung neoplasms; Lymphocytes; Neutrophils; Radiation pneumonitis; Radiotherapy | Humans; Lung; Lung Diseases, Interstitial; Lung Injury; Lung Neoplasms; Radiation Injuries; Radiation Pneumonitis; Retrospective Studies; C reactive protein; cisplatin; durvalumab; etoposide; gemcitabine; paclitaxel; absolute lymphocyte count; absolute neutrophil count; adult; aged; Article; blood; controlled study; disease severity; female; follow up; human; interstitial lung disease; lung cancer; lung injury; major clinical study; male; multivariate logistic regression analysis; national health organization; neutrophil lymphocyte ratio; overall survival; radiation dose; radiation injury; retrospective study; complication; interstitial lung disease; lung; lung injury; lung tumor; radiation pneumonia | English | 2024 | 2024-03 | 10.1016/j.radonc.2023.110053 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Towards ultra-stable and dendrite-suppressed Li-metal batteries: Ion-regulating graphene-modified separators | The practical application of metallic lithium (Li) anodes is hindered by nonuniform Li deposition/dissolution, as well as poor electrochemical reversibility during cycling. To address these challenges, surface modification of polymer separators with functional materials has been extensively explored. In this study, two distinct surface- modifying layers composed of MnOx x and polydopamine (PDA) are applied to modify the surface of graphenecoated polypropylene separators (G@PP). Both MnOx and PDA, which are formed through the graphene layer, significantly enhance the intrinsic electrolyte wettability of G@PP, resulting in a homogeneous Li-ion flux. Furthermore, the lithiophilic properties revealed by DFT and COMSOL analyses synergize with the hydrophilic characteristics, resulting in a more stable electrochemical performance in Li-metal batteries (LMBs). The enhanced electrolyte permeability of the coating layer allows Li-Cu cells with MnOx-modified x-modified graphene-coated PP (MG@PP) and PDA-modified graphene-coated PP (PG@PP) separators to exhibit significantly improved cycle stability compared with Li-Cu cells with G@PP separators. Interestingly, Li-S cells equipped with MG@PP and PG@PP separators exhibit also enhanced electrochemical performance compared with Li-S cells with G@PP separators. These results highlight that surface engineering of separator-coating materials along with hydrophilic and lithiophilic materials enhances both long-term cycle stability and electrochemical kinetics in LMBs. | Choi, Wootaek; Park, Minsu; Woo, Sujeong; Kim, Hyunwoo; Kang, Min Sung; Choi, Junghyun; Cho, Sung Beom; Kim, Taehoon; Kim, Patrick Joohyun | Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Korea Inst Mat Sci KIMS, Composites Res Div, Chang Won 51508, South Korea; Gachon Univ, Sch Chem Biol & Battery Engn, Seongnam Si 13120, Gyeonggi Do, South Korea; Ajou Univ, Dept Mat Sci & Engn, Suwon 16499, South Korea; Ajou Univ, Dept Energy Syst Res, Suwon 16499, South Korea | 59301545300; 57402583800; 59137762800; 57210863506; 58062197300; 59883103900; 48461004400; 57449684100; 57195611779 | junghchoi@gachon.ac.kr;csb@ajou.ac.kr;tkim67@kims.re.kr;pjkim@knu.ac.kr; | CARBON | CARBON | 0008-6223 | 1873-3891 | 230 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 11.6 | 10.1 | 0.82 | 2025-05-07 | 3 | 3 | Lithium metal anode; Wettability enhanced graphene; Hydrophilic separator; Homogeneous Li-ion flux | COMPOSITE SEPARATOR; WETTABILITY; ENERGY; PERFORMANCE | Homogeneous Li-ion flux; Hydrophilic separator; Lithium metal anode; Wettability enhanced graphene | Electrolytes; Plastic coatings; Separators; Graphenes; Homogeneous lithium-ion flux; Hydrophilic separator; Hydrophilics; Ion fluxes; Lithium ions; Lithium metal anode; Lithium metals; Polydopamine; Wettability enhanced graphene; Wetting | English | 2024 | 2024-11 | 10.1016/j.carbon.2024.119576 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Multifunctional carbon dots originated from waste garlic peel for rapid sensing of heavy metals and fluorescent imaging of 2D and 3D spheroids cultured fibroblast cells | Here, we prepared sulfur and nitrogen self-doped carbon dots derived from garlic peel extract (GPSNCDs) using a hydrothermal method. The as-synthesized GPSNCDs were confirmed using Fourier-transform infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and transmission electron microscopy. The analytical techniques indicate that the resulting GPSNCDs exhibit distinct emissive carbon-core with functionalities (owing to various ligands in the GPSNCDs). These functionalities are responsible for excellent hydrophilic and optical properties, including excitation-dependent emission and anti-photobleaching. Fluorescence intensities of GPSNCDs were quenched in the existence of Mn2+ and Fe3+ ions. This indicates that the GPSNCDs were sensitive to Fe3+ and Mn2+ ions with a limited range from 5 to 50 mu M and showed lower recognition at similar to 0.75 and 0.95 mu M, respectively. In addition, the sensing results were generated in a short time (20 s). The cytotoxicity of GPSNCDs was tested to demonstrate that they are sufficiently safe to use for cellular imaging. The novel fluorescent GPSNCDs-based sensor can be used as a high-performance sensor for environmental monitoring. Further, GPSNCDs showed greater biocompatibility with normal fibroblast cells, and In Vitro fluorescent imaging of GPSNCDs revealed strong fluorescence signals in the two-dimensional (2D) and threedimensional (3D) spheroids cultured fibroblast cells. The properties mentioned above demonstrate that the GPSNCDs can be applied to imaging normal cells without further modifications. | Krishnaiah, Prakash; Atchudan, Raji; Perumal, Suguna; Gangadaran, Prakash; Manoj, Devaraj; Ahn, Byeong-Cheol; Kumar, Raju Suresh; Almansour, Abdulrahman I.; Lee, Yong Rok; Jeon, Byong-Hun | Hanyang Univ, Dept Earth Resources & Environm Engn, 222 Wangsimni Ro, Seoul 04763, South Korea; Yeungnam Univ, Sch Chem Engn, Gyongsan 38541, South Korea; Saveetha Inst Med & Tech Sci, Saveetha Sch Engn, Dept Chem, Chennai 602105, Tamil Nadu, India; Sejong Univ, Dept Chem, Seoul 143747, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, BK21 FOUR KNU Convergence Educ Program Biomed Sci, Daegu 41944, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Nucl Med, Daegu 41944, South Korea; Karpagam Acad Higher Educ, Dept Chem, Coimbatore 641021, Tamil Nadu, India; Karpagam Acad Higher Educ, Ctr Mat Chem, Coimbatore 641021, Tamil Nadu, India; King Saud Univ, Coll Sci, Dept Chem, Riyadh 11451, Saudi Arabia | RAJI, ATCHUDAN/C-9904-2017; Gangadaran, Prakash/AAV-3102-2021; Lee, Yong/K-6373-2015; Jeon, Byong-Hun/AAF-4352-2020; perumal, suguna/N-9075-2017; Raju, Suresh Kumar/ABC-7605-2020; Manoj, Devaraj/N-6903-2019; Krishnaiah, Prakash/AAJ-5159-2021; Kumar, Raju Suresh/ABC-7605-2020; Almansour, Abdulrahman/AAY-8328-2021 | 57190618232; 26648054700; 56673798900; 54393130400; 49961897200; 7202791511; 36100384200; 6603003502; 57330662900; 57653536800 | atchudanr@yu.ac.kr;yrlee@yu.ac.kr;bhjeon@hanyang.ac.kr; | SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY | SPECTROCHIM ACTA A | 1386-1425 | 1873-3557 | 304 | SCIE | SPECTROSCOPY | 2024 | 4.6 | 10.2 | 5.3 | 2025-05-07 | 13 | 17 | Garlic peel; Carbon dots; Fluorescence sensor; Detection of metal ions; Cellular imaging | GREEN SYNTHESIS; RAMAN-SPECTROSCOPY; IN-VITRO; NITROGEN; FACILE; SULFUR; PROBE; FE3+; GENERATION; ION | Carbon dots; Cellular imaging; Detection of metal ions; Fluorescence sensor; Garlic peel | Biocompatibility; Carbon; Cell culture; Fibroblasts; Fluorescence imaging; Fourier transform infrared spectroscopy; Heavy metals; High resolution transmission electron microscopy; Optical properties; Photobleaching; X ray photoelectron spectroscopy; Carbon dots; Cellular imaging; Detection of metal ion; Fe 3+; Fibroblast cells; Fluorescence sensors; Fluorescent imaging; Garlic peel; Metals ions; Self-doped; Metal ions | English | 2024 | 2024-01-05 | 10.1016/j.saa.2023.123422 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Synthesis and characterization of X (X = Ni or Fe) modified BaTiO 3 for effective degradation of Reactive Red 120 dye under UV-A light and its biological activity | For the sustainable advancement of industrial expansion that is environmentally conscious, harmful dyes must be removed from wastewater. Untreated effluents containing colors have the potential to harm the ecosystem and pose major health risks to people, animals, and aquatic life. Here, we have fabricated Ni or Fe modified with BaTiO 3 materials and effectively utilized them for Reactive Red 120 (RR 120) dye degradation under UV-A light. The synthesized materials were characterized, and their structural, and photo -physical properties were reported. Phase segregation was not present in the XRD pattern, as evidenced by the absence of secondary phase peaks linked to iron, nickel, or oxides. Low metal ion concentrations may be the cause of this, and the presence of those elements was confirmed by XPS measurements. The Raman spectra of the BaTiO 3 /Ni and BaTiO 3 /Fe samples show a widened peak at 500 cm - 1 , which suggests that Ni or Fe are efficiently loaded onto the BaTiO 3 . RR 120 dye photodegradation under UV light conditions was effectively catalyzed by BaTiO 3 /Fe, as evidenced by its superior performance in the UV irradiation technique over both BaTiO 3 and BaTiO 3 /Ni. Compared to bare BaTiO 3 , both metal -modified materials efficiently degraded the RR 120 dye. Acidic pH facilitated the degradation process, which makes sense given that the heterogeneous photo -Fenton reaction was the mechanism of degradation along with BaTiO 3 sensitization. High -acidity sewage can be dangerous and carcinogenic, and conventional biological treatment methods are not appropriate for managing it. In the current investigation, it may be used to treat color effluents with extremely low pH levels. Additionally, the ability of the produced nanocomposites to inhibit the growth of twenty pathogens was examined, along with two fungi, fifteen Gramnegative Bacilli (GNB), one Gram-positive Bacilli (GPB), and two Gram-positive Cocci (GBC). | Balu, Krishnakumar; Abisheik, T.; Niyitanga, Theophile; Kumaravel, Sakthivel; Ali, Wahid; Khan, Mohammad Ehtisham; Ali, Syed Kashif; Bashiri, Abdullateef H.; Zakri, Waleed; Pandiyan, V. | Saveetha Inst Med & Tech Sci SIMATS, Inst Bioinformat, Saveetha Sch Engn, Chennai 602105, Tamil Nadu, India; Univ Seville, Dept Ingn & Ciencia Mat & Transporte, ETS Ingn, Avda Camino Descubrimientos S-N, Seville 41092, Spain; Bharathidasan Univ, Nehru Mem Coll Autonomous, Dept Phys, Tiruchirappalli 621007, Tamil Nadu, India; Yeungnam Univ, Sch Mat Sci & Engn, Gyongsan 38541, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Jazan Univ, Coll Appl Ind Technol, Dept Chem Engn Technol, Jazan 45142, Saudi Arabia; Jazan Univ, Coll Sci, Dept Phys Sci, Chem Div, POB 114, Jazan 45142, Saudi Arabia; Jazan Univ, Coll Sci, Nanotechnol Res Unit, POB 114, Jazan 45152, Saudi Arabia; Jazan Univ, Coll Engn, Dept Mech Engn, Jazan 45142, Saudi Arabia | Niyitanga, Theophile/GLQ-7732-2022; Ali, Syed/LFU-4237-2024; Balu, Krishnakumar/H-9038-2019; Ali, Wahid/U-7460-2017; Khan, Mohammad/J-5169-2019; KUMARAVEL, SAKTHIVEL/KBC-0974-2024 | 22235198500; 58864151200; 57195354646; 57212580936; 57188765517; 56562104900; 57189842280; 57197781157; 57201637480; 36904853800 | kbalu@us.es;t.niyitanga@yu.ac.kr;wzali@jazanu.edu.sa;pandiyanphy@gmail.com; | SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY | SPECTROCHIM ACTA A | 1386-1425 | 1873-3557 | 320 | SCIE | SPECTROSCOPY | 2024 | 4.6 | 10.2 | 2.45 | 2025-05-07 | 7 | 6 | BaTiO 3; UV-A light; Photodegradation; Reusability; Antimicrobial activity | ENHANCED PHOTOCATALYTIC ACTIVITY; HYDROTHERMAL SYNTHESIS; HYDROGEN EVOLUTION; NANOTUBE ARRAYS; NANOPARTICLES; FABRICATION; PEROVSKITE; COMPOSITE; SRTIO3 | Antimicrobial activity; BaTiO<sub>3</sub>; Photodegradation; Reusability; UV-A light | Barium Compounds; Coloring Agents; Iron; Nickel; Photolysis; Rhodamines; Spectrum Analysis, Raman; Titanium; Triazines; Ultraviolet Rays; Water Pollutants, Chemical; Aquatic ecosystems; Effluents; Health risks; Lactic acid; Metal ions; Nickel oxide; Oxidation; Sewage; barium derivative; barium titanate(IV); coloring agent; iron; nickel; reactive red 120 dye; rhodamine; titanium; triazine derivative; Anti-microbial activity; Aquatic life; Dye degradation; Industrial expansion; Photo degradation; Photophysical properties; Reactive red 120; Synthesis and characterizations; Synthesized materials; UV-A light; chemistry; photolysis; Raman spectrometry; ultraviolet radiation; water pollutant; Reusability | English | 2024 | 2024-11-05 | 10.1016/j.saa.2024.124556 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Development of a rapid screening method utilizing 2D LC for effect-directed analysis in the identification of environmental toxicants | Effect-directed analysis (EDA) is a crucial tool in environmental toxicology, effectively integrating toxicity testing with chemical analysis. The conventional EDA approach, however, presents challenges such as significant solvent consumption, extended analysis time, labor intensity, and potential contamination risks. In response, we introduce an innovative alternative to the conventional EDA. This method utilizes the MTT bioassay and online two-dimensional liquid chromatography (2D LC) coupled with high-resolution mass spectrometry (HR-MS), significantly reducing the fractionation steps and leveraging the enhanced sensitivity of the bioassay and automated chemical analysis. In the chemical analysis phase, a switching valve interface is employed for comprehensive analysis. We tested the performance of both the conventional and our online 2D LC-based methods using a household product. Both methods identified the same number of toxicants in the sample. Our alternative EDA is 22.5 times faster than the conventional method, fully automated, and substantially reduces solvent consumption. This novel approach offers ease, cost-effectiveness, and represents a paradigm shift in EDA methodologies.

| ○ | ○ | Article | Effect of microfibers induced toxicity in marine sedentary polychaete Hydroides elegans: Insight from embryogenesis axis | Presence of surgical face masks in the environment are more than ever before after the COVID-19 pandemic, and it poses a newer threat to aquatic habitats around the world due to microfibers (MFs) and other contaminants that get discharged when these masks deteriorate. The mechanism behind the developmental toxicity of MFs, especially released from surgical masks, on the early life stages of aquatic organisms are not well understood. Toxicity test were developed to examine the effects of MFs released from surgical facemask upon deterioration using the early gametes and early life stages of marine sedentary polychaete Hydroides elegans. For MFs release, cut pieces of face masks were allowed to degrade in seawater for different time points (1 day, 30 days and days) after which the fibers were obtained for further toxicity studies. The gametes of H. elegans were exposed the MFs (length < 20 mu m) separately for 20 min at a concentration of 50 MFs/ml before fertilization. In addition, we also analyzed the experimental samples for heavy metals and organic substances released from face masks. Our findings demonstrated that gametes exposed to MFs affected the percentage of successful development, considerably slowed down the mitotic cell division and significantly postponed the time of larval hatching and also produced an adverse effect during embryogenesis. When the sperm were exposed fertilization rate was decreased drastically, whereas when the eggs were exposed to MFs fertilization was not inhibited but a delay in early embryonic development observed. In addition the release of heavy metals and other volatile organics from the degrading face masks could also contribute to overall toxicity of these materials in environment. Our study thus shows that inappropriately discarded face masks and MFs and other pollutants released from such face masks could pose long-term hazard to coastal ecosystems. | Harikrishnan, Thilagam; Sivakumar, Priya; Sivakumar, Swetha; Arumugam, Sriramajayam; Raman, Thiagarajan; Singaram, Gopalakrishnan; Thangavelu, Muthukumar; Kim, Woong; Muthusamy, Govarthanan | Pachaiyappas Coll Men, Postgrad & Res Dept Zool, Chennai 600030, India; Prince Venkateswara Arts & Sci Coll, Dept Biotechnol, Chennai 600073, India; Ramakrishna Mission Vivekananda Coll Autonomous, Dept Zool, Chennai 600004, India; Dwaraka Doss Goverdhan Doss Vaishnav Coll, Dept Biotechnol, Chennai 600106, India; Jeonbuk Natl Univ, Dept BIN Convergence Tech, Dept PolymerNano Sci & Tech, 567 Baekje Dearo, Jeonju 54896, Jeollabuk Do, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daehak Ro, Daegu 41566, South Korea; Saveetha Univ, Saveetha Inst Med & Tech Sci, Saveetha Dent Coll & Hosp, Dept Biomat, Chennai 600077, India | Thangavelu, Muthukumar/E-3891-2016; K K, PRIYA/IAQ-8893-2023; Muthusamy, Govarthanan/C-1491-2014; Gopalakrishnan, Singaram/AEB-6454-2022 | 14326152000; 59577754700; 59109844600; 58631798500; 55219965200; 14624905900; 56355081300; 55581636400; 54881927600 | thilagampachaiyappas@gmail.com;gova.muthu@gmail.com; | SCIENCE OF THE TOTAL ENVIRONMENT | SCI TOTAL ENVIRON | 0048-9697 | 1879-1026 | 906 | SCIE | ENVIRONMENTAL SCIENCES | 2024 | 8 | 10.3 | 2.34 | 2025-04-16 | 8 | 8 | Surgical facemask; Microfibers; Hydroides elegans; Toxicity | LIFE STAGES; MICROPLASTICS; HEALTH; LARVAE | Hydroides elegans; Microfibers; Surgical facemask; Toxicity | Animals; Ecosystem; Embryonic Development; Humans; Male; Metals, Heavy; Pandemics; Plastics; Polychaeta; Semen; Animal cell culture; Aquatic organisms; Cell proliferation; Deterioration; Ecosystems; Heavy metals; Microfibers; heavy metal; volatile organic compound; heavy metal; plastic; Aquatic habitats; Earliest life; Elegans; Exposed to; Face masks; Fertilisation; Hydroides elegan; Life stages; Micro-fiber; Surgical facemask; aquatic organism; embryonic development; industrial waste; polychaete; toxicity; acute toxicity; animal experiment; Article; controlled study; cytotoxicity; developmental toxicity; embryo; embryotoxicity; fertilization; hatching; Hydroides elegans; mass fragmentography; microplastic pollution; mitosis inhibition; nonhuman; Polychaeta; sperm; toxicity testing; animal; ecosystem; embryo development; human; male; pandemic; Toxicity | English | 2024 | 2024-01-01 | 10.1016/j.scitotenv.2023.167579 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
