| ○ | ○ | Article | Adsorptive removal of o-phenylenediamine from water using dinitro-functionalized metal-organic framework: Beneficial contribution of the loaded nitro group to adsorption | Metal-organic frameworks (MOFs) composed of various functional groups, excluding nitro group, have been frequently studied for water purification via effective adsorption. In this study, the adsorption of an organic compound over a dinitro-functionalized MOF was investigated for the first time. o-Phenylenediamine (OPD) and DUT-52(Zr)-(NO2)2 were applied as the representative adsorbate and MOF with dinitro group, respectively. Despite decreased porosity, the dinitro-functionalization improved noticeably the adsorptive performance compared to the pristine MOF. The favorable contribution of dinitro-functionalization to OPD adsorption could be interpreted via both experimental and theoretical approaches. The electron-withdrawing nature of the nitro groups helped in increasing the efficiency of hydrogen bonding (between -NH2 of OPD and mu 3-O- of the MOF) because of the ready deprotonation of mu 3-OH. Similarly, the nitro group increases the 7C-7C interactions between the aromatic rings of MOF and OPD having an electron-rich ring. Additionally, the nitro group can make another hydrogen bond with an amino group of OPD. Furthermore, the DUT-52(Zr)-(NO2)2 was recyclable after simple solvent washing. Based on these results, it can be concluded that nitro-functionalization is an effective method for improving the adsorptive performance of MOFs for aromatic amines. | Lee, Gyudong; Nam, Ha Young; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem & Green Nano Mat, Res Ctr, Daegu 41566, South Korea | Jhung, Sung/AAO-6683-2021 | 57200987600; 59177391800; 6701659467 | sung@knu.ac.kr; | JOURNAL OF WATER PROCESS ENGINEERING | J WATER PROCESS ENG | 2214-7144 | 65 | SCIE | ENGINEERING, CHEMICAL;WATER RESOURCES;ENGINEERING, ENVIRONMENTAL | 2024 | 6.7 | 6.5 | 0 | 2025-05-07 | 0 | 0 | Adsorption; Dinitro group; Metal -organic frameworks | P-ARSANILIC ACID; AROMATIC-AMINES; WASTE-WATER; DNA-DAMAGE; SAMPLES; DEGRADATION; CATALYSIS; MOFS; XPS | Adsorption; Dinitro group; Metal-organic frameworks; O-phenylenediamine | English | 2024 | 2024-08 | 10.1016/j.jwpe.2024.105791 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Automated scoring and augmented reality visualization software program for evaluating tooth preparations | Statement of problem. Tooth preparation is an essential part of prosthetic dentistry; however, traditional evaluation methods involve subjective visual inspection that is prone to examiner variability. Purpose. The purpose of this study was to investigate a newly developed automated scoring and augmented reality (ASAR) visualization software program for evaluating tooth preparations. Material and methods. A total of 122 tooth models (61 anterior and 61 posterior teeth) prepared by dental students were evaluated by using visual assessments that were conducted by students and an expert, and auto assessment that was performed with an ASAR software program by using a 3-dimensional (3D) point-cloud comparison method. The software program offered comprehensive functions, including generating detailed reports for individual test models, producing a simultaneous summary score report for all tested models, creating 3D color-coded deviation maps, and forming augmented reality quick-response (AR-QR) codes for online data storage with AR visualization. The reliability and efficiency of the evaluation methods were measured by comparing tooth preparation assessment scores and evaluation time. The data underwent statistical analysis using the Kruskal-Wallis test, followed by Mann-Whitney U tests for pairwise comparisons adjusted with the Benjamini-Hochberg method (alpha=.05). Results. Significant differences were found across the evaluation methods and tooth types in terms of preparation scores and evaluation time (P<.001). A significant difference was observed between the auto- and student self-assessment methods (P<.001) in scoring both the anterior and posterior tooth preparations. However, no significant difference was found between the auto- and expert-assessment methods for the anterior (P=.085) or posterior (P=.14) tooth preparation scores. Notably, the auto-assessment method required significantly shorter time than the expert- and self-assessment methods (P<.001) for both tooth types. Additionally, significant differences in evaluation time between the anterior and posterior tooth were observed in both self- and expert-assessment methods (P<.001), whereas the evaluation times for both the tooth types with the auto-assessment method were statistically similar (P=.32). Conclusions. ASAR-based evaluation is comparable with expert-assessment while exhibiting significantly higher time efficiency. Moreover, AR-QR codes enhance learning and training experiences by facilitating online data storage and AR visualization. | Mai, Hang-Nga; Ngo, Hien Chi; Cho, Seok-Hwan; Lee, Du-Hyeong | Kyungpook Natl Univ, Inst Translat Res Dent, Daegu, South Korea; Univ Western Australia, UWA Dent Sch, Perth, Australia; Univ Iowa, Prosthodont Dept, Coll Dent & Dent Clin, Iowa City, IA USA; Kyungpook Natl Univ, Inst Translat Res Dent, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea | Mai, Hang-Nga/Q-9865-2018 | 56964780900; 7005488528; 12780626400; 35770948000 | deweylee@knu.ac.kr; | JOURNAL OF PROSTHETIC DENTISTRY | J PROSTHET DENT | 0022-3913 | 1097-6841 | 131 | 6 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2024 | 4.8 | 6.5 | 1.53 | 2025-05-07 | 2 | 2 | CROWN PREPARATION; TECHNOLOGY | Augmented Reality; Humans; Imaging, Three-Dimensional; Models, Dental; Reproducibility of Results; Software; Tooth Preparation; Tooth Preparation, Prosthodontic; adult; article; augmented reality; controlled study; dental student; dental surgery; human; information storage; Kruskal Wallis test; learning; male; rank sum test; reliability; self evaluation; software; tooth; dental model; dental surgery; procedures; reproducibility; three-dimensional imaging | English | 2024 | 2024-06 | 10.1016/j.prosdent.2024.02.008 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Efficacy and Safety of Metformin and Atorvastatin Combination Therapy vs. Monotherapy with Either Drug in Type 2 Diabetes Mellitus and Dyslipidemia Patients (ATOMIC): Double-Blinded Randomized Controlled Trial | Background: It is well known that a large number of patients with diabetes also have dyslipidemia, which significantly increases the risk of cardiovascular disease (CVD). This study aimed to evaluate the efficacy and safety of combination drugs consisting of metformin and atorvastatin, widely used as therapeutic agents for diabetes and dyslipidemia. Methods: This randomized, double-blind, placebo-controlled, parallel-group and phase III multicenter study included adults with glycosylated hemoglobin (HbA1c) levels >7.0% and 100 and <250 mg/dL. One hundred eighty-five eligible subjects were randomized to the combination group (metformin+atorvastatin), metformin group (metformin+atorvastatin placebo), and atorvastatin group (atorvastatin+metformin placebo). The primary efficacy endpoints were the percent changes in HbA1c and LDL-C levels from baseline at the end of the treatment. Results: After 16 weeks of treatment compared to baseline, HbA1c showed a significant difference of 0.94% compared to the atorvastatin group in the combination group (0.35% vs. -0.58%, respectively; P < 0.0001), whereas the proportion of patients with increased HbA1c was also 62% and 15%, respectively, showing a significant difference (P< P < 0.001). The combination group also showed a significant decrease in LDL-C levels compared to the metformin group (-55.20% vs. -7.69%, P < 0.001) without previously unknown adverse drug events. Conclusion: The addition of atorvastatin to metformin improved HbA1c and LDL-C levels to a significant extent compared to metformin or atorvastatin alone in diabetes and dyslipidemia patients. This study also suggested metformin's preventive effect on the glucose-elevating potential of atorvastatin in patients with type 2 diabetes mellitus and dyslipidemia, insufficiently controlled with exercise and diet. Metformin and atorvastatin combination might be an effective treatment in reducing the CVD risk in patients with both diabetes and dyslipidemia because of its lowering effect on LDL-C and glucose. | Lee, Jie-Eun;

| ○ | ○ | Article | Enhanced solar-powered H2 production from water splitting and sustainable wastewater treatment using interface-engineered ZnIn2S4/TiO2/Ti3C2 S-scheme heterocatalyst | Developing efficient photocatalysts that can degrade persistent antibiotics in water bodies and generate clean H-2 through water splitting is crucial for environmental and energy sustainability. This study introduces an advanced hierarchical ZnIn2S4/TiO2/Ti3C2 (ZIS/TO/TC) heterocatalyst for the efficient removal of amoxicillin (AXC) from wastewater and the production of H-2 through water reduction process under simulated solar illumination. The ZIS/TO/TC hybrids were fabricated via an in situ hydrothermal process, resulting in a hierarchical 3D structure that capitalizes on the complementary properties of each component. The design of the S-scheme heterojunction significantly enhances charge separation and transfer efficiency, offering improvements over traditional type-II or Z-scheme mechanisms. Notably, the optimized ZIS10/TO/TC hybrid catalyst demonstrated remarkable activity, achieving 100 % AXC degradation and excellent mineralization within 90 min, along with an H-2 production rate of 4104 mu mol h(-1) g(-1), significantly outperforming the individual components and exceeding previously reported efficiencies. The outstanding performance of the ZIS10/TO/TC hybrid is attributed to its enhanced light absorption properties, synergistic interactions among the ZIS, TO, and TC MXene, and the efficient S-scheme charge transfer mechanism, which facilitates effective charge separation and transfer while preserving the strong reducing and oxidizing capabilities of the components. Additionally, the ZIS10/TO/TC hybrid exhibited excellent stability over multiple photocatalytic tests, emphasizing its potential for practical applications. Therefore, this research demonstrates an advanced and highly efficient hybrid photocatalyst that offers a promising and sustainable solution for both integrated water treatment and renewable energy generation. | Lee, Dong-Eun; Jyothirmai, M.

| ○ | ○ | Article | Evaluation of photopolymer resins for dental prosthetics fabricated via the stereolithography process at different polymerization temperatures. Part II: Dimensional accuracy and fracture load of fixed dental prostheses | Statement of problem: Prostheses printed on a 3-dimensional (3D) printer need to undergo the postpolymerization process, which can increase the working time. However, it has been not suggested for reducing workload and improving the properties of prostheses in dental clinical practice. Purpose: The purpose of this in vitro study was to evaluate how the printing temperature impacts the dimensional accuracy and fracture load of 3D printed fixed dental prostheses (FDPs). Material and methods: Dental prostheses were printed at room temperature (RT), 50 degrees C, and 70 degrees C using a stereolithography 3D printer. Subsequently, after rinsing away residual monomer, the printed parts underwent the green condition (it was not subjected to any postprocessing) and postpolymerization. The mechanical properties of the printed FDPs were determined by loading to fracture (n=6). To evaluate their clinical applicability, the dimensional accuracy and fit of FDPs fabricated at various resin polymerization temperatures were measured (n=6). The 1-way analysis of variance was used to perform statistical comparisons, followed by the Tukey honestly significant difference test (alpha=.05). Results: The specimens printed at RT and 50 degrees C were better than those printed at 70 degrees C in terms of dimensional accuracy and fit (P<.05). Nonetheless, the dimensional accuracy and fit of the specimens printed at 70 degrees C were clinically acceptable. The fracture load of the 3-unit FDPs depended significantly on the printing temperature. Conclusions: The dimensional accuracy and fracture load of the 70 degrees C group were acceptable for FDP fabrication. Thus, the temperature of 70 degrees C without postprocessing may help make the procedure more efficient. | Lee, Ji -Min; Son, Keunbada; Lee, Kyu-Bok | Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Adv Dent Device Dev Inst, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu, South Korea; Kyungpook Natl Univ, Adv Dent Device Dev Inst, Sch Dent, Dept Prosthodont, 2177 Dalgubuldaero, Daegu 41940, South Korea | Lee, Ji Min/KCZ-2783-2024; Son, Keunbada/AAG-8089-2019; SON, Keunbada/AAG-8089-2019 | 57193811541; 57202916520; 15925571200 | kblee@knu.ac.kr; | JOURNAL OF PROSTHETIC DENTISTRY | J PROSTHET DENT | 0022-3913 | 1097-6841 | 131 | 2 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2024 | 4.8 | 6.5 | 0.76 | 2025-05-07 | 2 | 1 | POST CURING TEMPERATURE; ALL-CERAMIC CROWNS; SHRINKAGE-STRESS; INTERNAL FIT; BITE FORCE; PRECISION; KINETICS | Computer-Aided Design; Dental Prosthesis; Materials Testing; Polymerization; Printing, Three-Dimensional; Stereolithography; Temperature; computer aided design; materials testing; polymerization; stereolithography; temperature; three dimensional printing | English | 2024 | 2024-02 | 10.1016/j.prosdent.2023.10.024 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Evaluation of photopolymer resins for dental prosthetics fabricated via the stereolithography process at different polymerization temperatures—Part I: Conversion rate and mechanical properties | Statement of problem: Improvement in the mechanical properties of 3-dimensional (3D) printed dental prostheses is necessary to prevent wear caused by an antagonist or fracture. However, how different printing temperatures affect their mechanical properties is unclear. Purpose: The purpose of this in vitro study was to evaluate the mechanical properties of 3D printed parts fabricated at different printing temperatures. Material and methods: Photopolymer specimens were fabricated at 3 different temperatures (room temperature, 50 °C, and 70 °C) using a stereolithography 3D printer. After rinsing to remove the residual monomer, the specimens were divided into 2 groups: with or without postprocessing. The viscosity of the photopolymerization resin was measured while the temperature was increased. Furthermore, the double-bond conversion (DBC) of the printed part was evaluated (n=3). Mechanical properties were investigated via dynamic mechanical analysis (n=1) and tensile testing (n=5). Statistical comparisons were performed via 1-way analysis of variance, followed by the Tukey honestly significant difference test (α=.05). Results: The DBC rates of the green condition group increased from 66.67% to 86.33% with increasing temperature. In addition, these specimens exhibited improved mechanical properties and reduced residual monomer levels. Conclusions: Specimens fabricated at a temperature of 70 °C exhibited mechanical properties suitable for clinical application. © 2023 Editorial Council for The Journal of Prosthetic Dentistry | Lee, Ji-Min; Son, KeunBaDa; Lee, Kyu-Bok | Graduate student, Advanced Dental Device Development Institute, Department of Dental Science, Graduate School, Kyungpook National University, Daegu, South Korea; Research Professor, Advanced Dental Device Development Institute, Department of Dental Science, Graduate School, Kyungpook National University, Daegu, South Korea; Department of Prosthodontics, School of Dentistry, Kyungpook National University, Daegu, South Korea | 57193811541; 57202916520; 15925571200 | kblee@knu.ac.kr; | Journal of Prosthetic Dentistry | J PROSTHET DENT | 0022-3913 | 1097-6841 | 131 | 1 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2024 | 4.8 | 6.5 | 2.48 | 2025-04-16 | 3 | Materials Testing; Polymerization; Printing, Three-Dimensional; Stereolithography; Surface Properties; Temperature; materials testing; polymerization; stereolithography; surface property; temperature; three dimensional printing | English | Final | 2024 | 10.1016/j.prosdent.2023.10.015 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Review | Metabolic Dysfunction-Associated Steatotic Liver Disease in Type 2 Diabetes Mellitus: A Review and Position Statement of the Fatty Liver Research Group of the Korean Diabetes Association | Since the role of the liver in metabolic dysfunction, including type 2 diabetes mellitus, was demonstrated, studies on non-alcoholic fatty liver disease (NAFLD) and metabolic dysfunction-associated fatty liver disease (MAFLD) have shown associations between fatty liver disease and other metabolic diseases. Unlike the exclusionary diagnostic criteria of NAFLD, MAFLD diagnosis is based on the presence of metabolic dysregulation in fatty liver disease. Renaming NAFLD as MAFLD also introduced simpler diagnostic criteria. In 2023, a new nomenclature, steatotic liver disease (SLD), was proposed. Similar to MAFLD, SLD diagnosis is based on the presence of hepatic steatosis with at least one cardiometabolic dysfunction. SLD is categorized into metabolic dysfunction-associated steatotic liver disease (MASLD), metabolic dysfunction and alcohol-related/-associated liver disease, alcohol- related liver disease, specific etiology SLD, and cryptogenic SLD. The term MASLD has been adopted by a number of leading national and international societies due to its concise diagnostic criteria, exclusion of other concomitant liver diseases, and lack of stigmatizing terms. This article reviews the diagnostic criteria, clinical relevance, and differences among NAFLD, MAFLD, and MASLD from a diabetologist's perspective and provides a rationale for adopting SLD/MASLD in the Fatty Liver Research Group of the Korean Diabetes Association. | Bae, Jaehyun; Han, Eugene; Lee, Hye Won; Park, Cheol-Young; Chung, Choon Hee; Lee, Dae Ho; Cho, Eun-Hee; Rhee, Eun-Jung; Yu, Ji Hee; Park, Ji Hyun; Bae, Ji-Cheol; Park, Jung Hwan; Choi, Kyung Mook; Kim, Kyung-Soo; Seo, Mi Hae; Lee, Minyoung; Kim, Nan-Hee; Kim, So Hun; Lee, Won-Young; Lee, Woo Je; Choi, Yeon-Kyung; Lee, Yong-ho; Hwang, You-Cheol; Lyu, Young Sang; Lee, Byung-Wan; Cha, Bong-Soo | Hallym Univ, Coll Med, Kangnam Sacred Heart Hosp, Div Endocrinol & Metab,Dept Internal Med, Seoul, South Korea; Keimyung Univ, Dept Internal Med, Div Endocrinol & Metab, Sch Med, Daegu, South Korea; Keimyung Univ, Sch Med, Dept Obstet & Gynecol, Daegu, South Korea; Sungkyunkwan Univ, Kangbuk Samsung Hosp, Dept Internal Med, Div Endocrinol & Metab,Sch Med, Seoul, South Korea; Yonsei Univ, Dept Internal Med, Wonju Coll Med, Wonju, South Korea; Yonsei Univ, Res Inst Metab & Inflammat, Wonju Coll Med, Wonju, South Korea; Gachon Univ, Gil Med Ctr, Dept Internal Med, Coll Med, Incheon, South Korea; Kangwon Natl Univ, Kangwon Natl Univ Hosp, Sch Med, Sch Med, Chunchon, South Korea; Korea Univ, Coll Med, Dept Internal Med, Div Endocrinol & Metab, Seoul, South Korea; Jeonbuk Natl Univ, Jeonbuk Natl Univ Hosp, Dept Internal Med, Div Endocrinol & Metab,Med Sch, Jeonju 54907, South Korea; Sungkyunkwan Univ, Sch Med, Samsung Changwon Hosp, Div Endocrinol & Metab,Dept Internal Med, Gyeongsangnam Do, South Korea; Hanyang Univ, Coll Med, Coll Med, Div Endocrinol & Metab, Seoul, South Korea; CHA Univ, CHA Bundang Med Ctr, Dept Internal Med, Sch Med, Seongnam, South Korea; Soonchunhyang Univ, Gumi Hosp, Dept Internal Med, Div Endocrinol & Metab,Coll Med, Gumi, South Korea; Yonsei Univ, Dept Internal Med, Div Endocrinol & Metab, Coll Med, 50-1 Yonsei Ro, Seoul 03722, South Korea; Inha Univ, Dept Internal Med, Div Endocrinol & Metab, Coll Med, 100 Inha Ro, Incheon 22212, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Internal Med, Seoul, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Internal Med, Daegu 41404, South Korea; Kyung Hee Univ, Kyung Hee Univ Hosp Gangdong, Dept Med, Div Endocrinol & Metab,Dept Med, 892 Dongnam Ro, Seoul 05278, South Korea; Chosun Univ, Chosun Univ, Dept Internal Med, Div Endocrinol & Metab,Coll Med, Gwangju, South Korea | Park, Jung Hwan/AAA-1951-2022; Cho, Young/J-5669-2012; Park, Ji Hyun/KYQ-2814-2024; Kim, Nan/T-8627-2019; Lee, Da Young/AAA-1843-2021; Lee, Jae/AAF-5113-2021; Kim, Min/N-1961-2015; Hwang, You-Cheol/AAA-4616-2022; Wan, Lee/K-2649-2019; Choi, Kyung/AAL-7432-2021 | 59513638800; 56942969800; 57907713300; 7408418273; 57293078600; 56228667700; 55565521700; 7004174408; 14527795900; 57203846500; 37021265600; 55716953800; 7403949874; 57204587343; 54397705300; 57201903857; 57196299667; 56499561100; 57928301300; 56638806600; 35335932600; 56424219700; 23670001600; 57191958642; 15763315600; 57959977300 | bwanlee@yuhs.ac; | DIABETES & METABOLISM JOURNAL | DIABETES METAB J | 2233-6079 | 2233-6087 | 48 | 6 | SCIE | ENDOCRINOLOGY & METABOLISM | 2024 | 8.5 | 6.5 | 0.28 | 2025-05-07 | 2 | 3 | Diabetes mellitus; type 2; Metabolic dysfunction-associated steatotic liver disease; Non-alcoholic fatty liver disease | NONALCOHOLIC STEATOHEPATITIS; FIBROSIS; NAFLD; EPIDEMIOLOGY; PREVALENCE; MORTALITY; DIAGNOSIS | Diabetes mellitus, type 2; Metabolic dysfunction-associated steatotic liver disease; Non-alcoholic fatty liver disease | Diabetes Mellitus, Type 2; Fatty Liver; Humans; Non-alcoholic Fatty Liver Disease; Republic of Korea; alcohol liver disease; clinical significance; diabetes mellitus; diabetologist; diagnosis; drug comparison; etiology; fatty liver; human; Korean (people); liver disease; major clinical study; metabolic disorder; metabolic fatty liver; non insulin dependent diabetes mellitus; nonalcoholic fatty liver; review; complication; epidemiology; metabolism; South Korea | English | 2024 | 2024-11 | 10.4093/dmj.2024.0541 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Recycling of spent superabsorbent polymer into nitrogen-doped carbon catalyst for enhanced antibiotic degradation in groundwater | Polyacrylate (PA), used as a superabsorbent material, is found in household waste, including diapers, napkins, and ice packs; these items are disposed in landfills, raising concerns regarding their environmental impact and management. The beneficial use of PA -derived waste as a carbon catalyst was examined. Nitrogen -doped superabsorbent polymer -derived carbon (N-SAPC) catalysts were designed to activate peroxymonosulfate (PMS) for the removal of the persistent trimethoprim (TMP) pollutant. N-SAPC carbonized at 800 degrees C (N-SAPC 800 ) exhibited improved adsorption and catalytic performance due to its high specific surface area (216.68 m 2 g -1 ), pore volume (0.070 cm 3 g -1 ), and graphitic degree (89.56 %). A 97.78 % removal of TMP (10 mg L -1 ) was achieved in 180 min using N-SAPC 800 (0.1 g L -1 ) and PMS (1.0 mM) at pH 6.8. N-SAPC 800 was effective over a pH range of 5 -11. The breakdown of TMP using N-SAPC 800 /PMS was primarily due to improved electron transfer and the production of non -radical species ( 1 O 2 ) on the reactive sites of N-SAPC 800 . These sites include defects and functional groups like C -- O and C - N within the graphitic structures, which were created by N -doping. TMP degradation pathways were proposed according to the by-products formed, and the toxicity of these intermediates was assessed. TMP degradation was slightly inhibited in natural groundwater (NGW), which was overcome by increasing the PMS and/or N-SAPC 800 concentrations. The catalyst also demonstrated successful removal of other antibiotics such as ciprofloxacin, tetracycline, and sulfamethoxazole with removal percentages of 88.92%, 100%, and 94.82 %, respectively. This study emphasizes the potential of N-SAPC 800 /PMS in addressing antibiotic contamination in groundwater. | Al Masud, Md Abdullah; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | Masud, Md Abdullah Al/JEF-1055-2023 | 57542255300; 23019870800 | wshin@knu.ac.kr; | JOURNAL OF WATER PROCESS ENGINEERING | J WATER PROCESS ENG | 2214-7144 | 64 | SCIE | ENGINEERING, CHEMICAL;WATER RESOURCES;ENGINEERING, ENVIRONMENTAL | 2024 | 6.7 | 6.5 | 0.97 | 2025-05-07 | 4 | 5 | Trimethoprim; Peroxymonosulfate; Superabsorbent polymer; Singlet oxygen; Electron transfer | WATER | Electron transfer; Peroxymonosulfate; Singlet oxygen; Superabsorbent polymer; Trimethoprim | English | 2024 | 2024-07 | 10.1016/j.jwpe.2024.105567 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Reducing Oxidative Stress and Inflammation by Pyruvate Dehydrogenase Kinase 4 Inhibition Is Important in Prevention of Renal Ischemia-Reperfusion Injury in Diabetic Mice | Background: Reactive oxygen species (ROS) and inflammation are reported to have a fundamental role in the pathogenesis of ischemia-reperfusion (IR) injury, a leading cause of acute kidney injury. The present study investigated the role of pyruvate dehydrogenase kinase 4 (PDK4) in ROS production and inflammation following IR injury. Methods: We used a streptozotocin-induced diabetic C57BL6/J mouse model, which was subjected to IR by clamping both renal pedicles. Cellular apoptosis and inflammatory markers were evaluated in NRK-52E cells and mouse primary tubular cells after hypoxia and reoxygenation using a hypoxia work station. Results: Following IR injury in diabetic mice, the expression of PDK4, rather than the other PDK isoforms, was induced with a marked increase in pyruvate dehydrogenase E1 alpha (PDHE1 alpha) phosphorylation. This was accompanied by a pronounced ROS activation, as well as tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL -6), interleukin-13 (IL -13), and monocyte chemoattractant protein -1 (MCP -1) production. Notably, sodium dichloroacetate (DCA) attenuated renal IR injury -induced apoptosis which can be attributed to reducing PDK4 expression and PDHE1 alpha phosphorylation levels. DCA or shPdk4 treatment reduced oxidative stress and decreased TNF-alpha, IL -6, IL -13, and MCP -1 production after IR or hypoxia-reoxygenation injury. Conclusion: PDK4 inhibition alleviated renal injury with decreased ROS production and inflammation, supporting a critical role for PDK4 in IR mediated damage. This result indicates another potential target for reno-protection during IR injury; accordingly, the role of PDK4 inhibition needs to be comprehensively elucidated in terms of mitochondrial function during renal IR injury. | Khang, Ah Reum; Kim, Dong Hun; Kim, Min-Ji; Oh, Chang Joo; Jeon, Jae-Han; Choi, Sung Hee; Lee, In-Kyu | Pusan Natl Univ, Yangsan Hosp, Sch Med, Dept Internal Med, Yangsan, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Biomed Sci, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Res Inst Aging & Metab, Sch Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Leading Edge Res Ctr Drug Discovery & Dev Diabet &, Daegu, South Korea; Seoul Natl Univ, Bundang Hosp, Coll Med, Dept Internal Med, Seongnam, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Internal Med, 130 Dongdeok Ro, Daegu 41944, South Korea | KHANG, AHREUM/JHV-0081-2023; Kim, Minji/AAQ-2339-2020; Choi, Sung-hee/J-5689-2012 | 38861924800; 57223020477; 57206189095; 14049080600; 36910340400; 56181488400; 59060573600 | leei@knu.ac.kr; | DIABETES & METABOLISM JOURNAL | DIABETES METAB J | 2233-6079 | 2233-6087 | 48 | 3 | SCIE | ENDOCRINOLOGY & METABOLISM | 2024 | 8.5 | 6.5 | 3.32 | 2025-05-07 | 7 | 7 | Acute kidney injury; Diabetes mellitus; Inflammation; Ischemia; Pyruvate dehydrogenase kinase 4; Reactive oxygen species; Reperfusion | MYOCARDIAL-ISCHEMIA; METABOLIC SWITCH; MECHANISMS; EXPRESSION; FAILURE; SUSCEPTIBILITY; ADAPTATION; STARVATION; APOPTOSIS; HYPOXIA | Acute kidney injury; Diabetes mellitus; Inflammation; Ischemia; Pyruvate dehydrogenase kinase 4; Reactive oxygen species; Reperfusion | Acute Kidney Injury; Animals; Apoptosis; Diabetes Mellitus, Experimental; Diabetic Nephropathies; Dichloroacetic Acid; Inflammation; Kidney; Male; Mice; Mice, Inbred C57BL; Oxidative Stress; Phosphorylation; Pyruvate Dehydrogenase (Lipoamide); Pyruvate Dehydrogenase Acetyl-Transferring Kinase; Reactive Oxygen Species; Reperfusion Injury; 3 nitrotyrosine; 4 hydroxynonenal; caspase 3; creatinine; dichloroacetic acid; interleukin 1beta; interleukin 6; monocyte chemotactic protein 1; neutrophil gelatinase associated lipocalin; pyruvate dehydrogenase; pyruvate dehydrogenase E1alpha; pyruvate dehydrogenase kinase 4; reactive oxygen metabolite; short hairpin RNA; tumor necrosis factor; unclassified drug; dichloroacetic acid; Pdk4 protein, mouse; pyruvate dehydrogenase; pyruvate dehydrogenase E1alpha subunit; pyruvate dehydrogenase kinase; reactive oxygen metabolite; animal cell; animal experiment; animal model; animal tissue; apoptosis; Article; controlled study; creatinine blood level; diabetes mellitus; enzyme inhibition; enzyme phosphorylation; hypoxia; inflammation; kidney tissue; male; mitochondrion; mouse; mRNA expression level; nonhuman; NRK-52E cell line; oxidative stress; protein expression level; renal ischemia reperfusion injury; renal protection; reoxygenation; streptozotocin-induced diabetes mellitus; upregulation; urea nitrogen blood level; acute kidney failure; animal; apoptosis; C57BL mouse; complication; diabetic nephropathy; drug effect; etiology; experimental diabetes mellitus; kidney; metabolism; pathology; phosphorylation; prevention and control; reperfusion injury | English | 2024 | 2024-05 | 10.4093/dmj.2023.0196 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Solution-processed nanoporous and faceted CuO electrocatalyst for enhanced solar-to-hydrogen and nitrate-to-ammonia production | Porosity control and facet engineering of electrocatalysts are critical for sustainable hydrogen production and wastewater upcycling into value-added chemicals. Herein, we report the sol-gel synthesis of a nanoporous faceted cupric oxide (nf-CuO) electrocatalyst film via a controlled polyesterification reaction. The formation mechanism of the unique nf-CuO morphology was analyzed and proposed. Notably, ligand additives such as ethylene glycol, citric acid, and polyethylene glycol function as morphology-controlling agents, and the polyesterification reaction between ligands can form covalent gel networks with trapped Cu ions. During thermal annealing, nucleation and nanoparticle growth along the covalent gel network enabled the formation of nanoporous and multifaceted CuO electrocatalysts on fluorine-doped SnO2 substrates, which was verified using ex-situ thermogravimetric/differential thermal analysis, Fourier transform infrared spectroscopy and transmission electron microscopy. The optimally synthesized nf-CuO exhibited high electrocatalytic activity in both photoelectrochemical hydrogen production and electrochemical nitrate reduction reactions. This enhanced performance was attributed to the nanoporosity-induced light-harvesting enhancement, enlarged surface area, and increased number of active sites. Our work emphasizes the importance of additive engineering to simultaneously control the porosity and facets of electrocatalysts and demonstrates its effectiveness in enhancing the electrocatalytic activity of diverse energy conversion devices. | Tan, Runfa; Kang, Min Je; Qu, Li; Hwang, Sung Won; Hong, Seo Yeong; Jeong, Yoo Jae; Han, Hyun Soo; Kim, Dong Hoe; Lee, Sangwook; Cho, In Sun | Ajou Univ, Dept Energy Syst Res, Suwon 16499, South Korea; Ajou Univ, Dept Mat Sci & Engn, Suwon 16499, South Korea; Stanford Univ, Dept Mech Engn, Stanford, CA 94306 USA; Korea Univ, Dept Mat Sci & Engn, Seoul 02855, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | Lee, Sangwook/O-9166-2015; Han, Hyun Soo/I-4803-2019; Cho, In Sun/H-6557-2011 | 57224830477; 57224195151; 57654650400; 57190062486; 57796001900; 57224200546; 25642609200; 56366898500; 57203597324; 35739919200 | wook2@knu.ac.kr;insuncho@ajou.ac.kr; | JOURNAL OF WATER PROCESS ENGINEERING | J WATER PROCESS ENG | 2214-7144 | 61 | SCIE | ENGINEERING, CHEMICAL;WATER RESOURCES;ENGINEERING, ENVIRONMENTAL | 2024 | 6.7 | 6.5 | 1.29 | 2025-05-07 | 6 | 6 | Cupric oxide; Nanoporous; Facet; Polyesterification; Photoelectrochemical hydrogen production; Electrocatalytic nitrate reduction | WATER | Cupric oxide; Electrocatalytic nitrate reduction; Facet; Nanoporous; Photoelectrochemical hydrogen production; Polyesterification | English | 2024 | 2024-05 | 10.1016/j.jwpe.2024.105322 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Synthesis of multifunctional Ti/RuO2-ZnO composite catalytic electrodes for electrochemical oxidation and hydrogen production from toluene-containing wastewater | Developing electrodes that effectively perform indirect oxidation on nondecomposable organic compounds is a key objective in electrochemical oxidation research. This study focuses on fabricating a Ti/RuO2-ZnO electrode through a simple pyrolysis method on a Ti substrate etched with hydrochloric acid. Hydrochloric acid etching played a pivotal role in enhancing coating stability by markedly increasing the Ti substrate's surface area and hydrophilicity. Analyzing the linear sweep voltammetry revealed that the electrode exhibited a low overvoltage of the oxygen evolution reaction, reaching 221 mV at 10 mA cm(-2), indicating effective use as an active anode. The electrode's performance was evaluated by removing toluene contained in a 0.1 M NaCl solution at pH 5. The electrochemical reaction generated active chlorine in the solution, oxidizing 98.66 % of toluene over 3 h and concurrently producing 25.62 mL of hydrogen. This study presents a simple and effective synthesis of a RuO2-based active anode, demonstrating its potential application not only in removing toluene from wastewater but also in hydrogen production. | Cho, Yong-Beom; Lee, Sung-Eun; Kim, Tae-Oh | Kumoh Natl Inst Technol, Dept Environm Engn, Gumi 39177, South Korea; Kumoh Natl Inst Technol, Dept Energy Engn Convergence, Gumi 39177, South Korea; Kyungpook Natl Univ, Inst Evaluat Safety & Qual Agr Prod, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea | Cho, Yong/F-4606-2014; Kim, Taeoh/F-4647-2012 | 58125602200; 55890041600; 9335312200 | cyb1977@kumoh.ac.kr;selpest@knu.ac.kr;tokim@kumoh.ac.kr; | JOURNAL OF WATER PROCESS ENGINEERING | J WATER PROCESS ENG | 2214-7144 | 64 | SCIE | ENGINEERING, CHEMICAL;WATER RESOURCES;ENGINEERING, ENVIRONMENTAL | 2024 | 6.7 | 6.5 | 1.29 | 2025-05-07 | 4 | 4 | Editor: Akeem Oladipo; Electrochemical oxidation; Anodic oxidation; Dimensionally stable anode; Kinetics; Hydrogen | BIOLOGICAL TREATMENT; ACTIVATED CARBON; PERFORMANCE; BDD; KINETICS; ANODE | Anodic oxidation; Dimensionally stable anode; Electrochemical oxidation; Hydrogen; Kinetics | English | 2024 | 2024-07 | 10.1016/j.jwpe.2024.105588 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A virtuous cycle for thermal treatment of polyvinyl chloride and fermentation of lignocellulosic biomass | In this study, a highly corrosive substance, hydrogen chloride (HCl), obtained through the dechlorination of polyvinyl chloride (PVC), was utilized for acid pretreatment in the production of lignocellulosic bioethanol. The study determined that the optimal concentration of HCl was 5 wt%, resulting in the highest sugar recovery of 85.98% from oak sawdust when treated at 130 degrees C for 2 h. The production of bioethanol (BE) by Pichia stipitis using the hydrolysates treated with 5% HCl and enzymes, supplemented with N-sources, demonstrated efficient productivity compared to the control group. To achieve a virtuous cycle, two residues from the dechlorination of PVC and saccharification of oak sawdust were pyrolyzed in a carbon dioxide (CO2) environment. The generation of carbon monoxide (CO) was significantly enhanced by the homogeneous reaction between CO2 and volatiles. This homogeneous reaction led to the modification of the compositional matrix in the oil. The generation of lowmolecular-weight hydrocarbons in oil was observed under CO2 conditions. To impart high reactivity to CO2, the catalytic pyrolysis of the residues was performed in the presence of Ni/SiO2. Indeed, the CO2 reactivity was catalytically enhanced, which greatly expedited the redox kinetics underlying the chemical reactions of CO2 with volatiles from PVC. The experimental findings provide a great avenue for hybridizing the thermochemical process of PVC and the biological bioethanol production process of lignocellulosic biomass. Such efforts are promising from the perspective of economic viability in the waste-to-energy and biofuel fields. | Park, Jonghyun; Yim, Jun Ho; Cho, Seong-Heon; Jung, Sungyup; Tsang, Yiu Fai; Chen, Wei-Hsin; Jeon, Young Jae; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Pukyong Natl Univ, Dept Microbiol, Busan 48513, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Educ Univ Hong Kong, Dept Sci & Environm Studies, Hong Kong 999077, Peoples R China; Educ Univ Hong Kong, State Key Lab Marine Pollut, Hong Kong 999077, Peoples R China; Natl Cheng Kung Univ, Dept Aeronaut & Astronaut, Tainan 701, Taiwan; Tunghai Univ, Res Ctr Smart Sustainable Circular Econ, Taichung 407, Taiwan; Natl Chin Yi Univ Technol, Dept Mech Engn, Taichung 411, Taiwan; Pukyong Natl Univ, Sch Marine & Fisheries Life Sci, Busan 48513, South Korea | Kwon, Eilhann/AGY-3339-2022; Chen, Wei-Hsin/S-2033-2018; Tsang, Yiu/AAJ-2524-2020 | 58544742000; 57205674301; 56583023200; 55073290800; 22954605700; 57200873137; 7201888480; 9240622100 | youngjaejeon@pknu.ac.kr;ek2148@hanyang.ac.kr; | APPLIED ENERGY | APPL ENERG | 0306-2619 | 1872-9118 | 362 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2024 | 11 | 6.6 | 0.59 | 2025-05-07 | 3 | 3 | Waste -to -energy; Polyvinyl chloride; Lignocellulosic biomass; Bioethanol; Syngas | POLYCYCLIC AROMATIC-HYDROCARBONS; CO-PYROLYSIS; BIOETHANOL PRODUCTION; PRETREATMENT; PVC; ETHANOL; DEGRADATION; CONVERSION; MECHANISM; CATALYSTS | Bioethanol; Lignocellulosic biomass; Polyvinyl chloride; Syngas; Waste-to-energy | Bioethanol; Biomass; Carbon dioxide; Chlorine compounds; Dechlorination; Ethanol; Hydrogen production; Nickel compounds; Redox reactions; Saccharification; Silicon compounds; Waste treatment; Acid pretreatment; Bio-ethanols; Homogeneous reaction; Hydrogen chloride; Ligno-cellulosics; Lignocellulosic biomass; Oak sawdust; Optimal concentration; Syn gas; Waste to energy; biofuel; carbon monoxide; dechlorination; fermentation; pyrolysis; reaction kinetics; viability; Carbon monoxide | English | 2024 | 2024-05-15 | 10.1016/j.apenergy.2024.123011 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

Physical frailty was evaluated using the Korean version of the FRAIL questionnaire, gait speed, and handgrip strength. Orthostatic hypertension was defined as a >= 20-mm Hg increase in systolic blood pressure within 3 minutes of standing and upright systolic blood pressure of >= 140 mm Hg.RESULTS:We analyzed the data of 2065 participants who had been enrolled until December 31, 2022. The mean age was 73.2 +/- 5.6 years, and 52.0% were female. The mean blood pressure was 137.1 +/- 14.9/75.1 +/- 9.7 mm Hg. Among the participants, 1886 (91.3%) showed normal response after standing, but 94 (4.6%) had orthostatic hypertension, and 85 (4.1%) had orthostatic hypotension. Orthostatic hypertension was associated with female sex, obesity, cognitive function, physical frailty, and lower quality of life. In the multivariable analysis, body mass index and frailty status were independently associated with orthostatic hypertension.CONCLUSIONS:Orthostatic hypertension is associated with physical frailty, cognitive impairment, and low quality of life in older patients with hypertension. Therefore, evaluation of orthostatic blood pressure changes to confirm orthostatic hypertension or hypotension in frail older adults will serve as an important diagnostic procedure in vulnerable patients. Further studies are required to identify the underlying mechanisms of this association. | Choi, Jung-Yeon; Ryu, Dong Ryeol; Lee, Hae-Young; Lee, Ju-Hee; Hong, Youjin; Park, Sue K.; Lee, Jang Hoon; Hwang, Seok-Jae; Kim, Kye Hun; Lee, Sun Hwa; Kim, Song Yi; Park, Jae-Hyeong; Kim, Sang-Hyun; Kim, Hack-Lyoung; Choi, Jung Hyun; Kim, Cheol-Ho; Cho, Myeong-Chan; Kim, Kwang-il | Seoul Natl Univ, Bundang Hosp, Dept Internal Med, Seongnam, South Korea; Kangwon Natl Univ, Sch Med, Dept Internal Med, Div Cardiol, Chunchon, South Korea; Seoul Natl Univ, Dept Internal Med, Coll Med, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Prevent Med, Seoul, South Korea; Seoul Natl Univ, Integrated Major Innovat Med Sci, Grad Sch, Seoul, South Korea; Seoul Natl Univ, Seoul Natl Univ Hosp, Coll Med, Dept Internal Med, Seoul, South Korea; Chungbuk Natl Univ, Coll Med, Dept Internal Med, Cheongju, South Korea; Chungbuk Natl Univ Hosp, Div Cardiol, Cheongju, South Korea; Chungbuk Natl Univ Hosp, Cardiocerebrovasc Ctr, Cheongju, South Korea; Seoul Natl Univ, Canc Res Inst, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Div Cardiol, Daegu, South Korea; Gyeongsang Natl Univ, Dept Internal Med, Gyeongsang Natl Univ Hosp, Coll Med, Jinju, South Korea; Chonnam Natl Univ Hosp, Dept Cardiovasc Med, Gwangju, South Korea; Jeonbuk Natl Univ, Jeonbuk Natl Univ Hosp, Dept Internal Med, Div Cardiol,Med Sch, Jeonju, South Korea; Jeju Natl Univ, Jeju Natl Univ Hosp, Coll Med, Dept Internal Med,Div Cardiol, Jeju, South Korea; Chungnam Natl Univ, Coll Med, Chungnam Natl Univ Hosp, Div Cardiol,Dept Internal Med, Daejeon, South Korea; Seoul Natl Univ, Seoul Metropolitan Govt, Dept Internal Med, Div Cardiol,Boramae Med Ctr, Seoul, South Korea; Pusan Natl Univ Hosp, Med Res Inst, Dept Internal Med, Div Cardiol, Busan, South Korea | Kim, Song-Yi/JAC-5358-2023; Park, Jae-Hyeong/AAD-9015-2021; lee, sun hwa/R-1431-2019; Kim, Cheol/J-5444-2012 | 56509684100; 59734016900; 56151235500; 57204073070; 57885302400; 8085325400; 54581258000; 36007319200; 56150430800; 57887827800; 35740671300; 36063048400; 49663680000; 17135448100; 56399550000; 58179428500; 58092080500; 57193847032 | kikim907@snu.ac.kr; | HYPERTENSION | HYPERTENSION | 0194-911X | 1524-4563 | 81 | 6 | SCIE | PERIPHERAL VASCULAR DISEASE | 2024 | 8.2 | 6.6 | 1.46 | 2025-05-07 | 3 | 4 | aged; blood pressure; frailty; orthostatic hypertension | BLOOD-PRESSURE; KOREAN VERSION; ADULTS; RISK; VALIDATION; MORTALITY; DISEASE | aged; blood pressure; frailty; orthostatic hypertension | Aged; Aged, 80 and over; Blood Pressure; Blood Pressure Determination; Female; Frail Elderly; Frailty; Hand Strength; Humans; Hypertension; Hypotension, Orthostatic; Male; Quality of Life; Republic of Korea; antihypertensive agent; aged; Article; blood pressure; cognition; controlled study; daily life activity; female; frailty; grip strength; human; major clinical study; male; mean arterial pressure; obesity; orthostatic blood pressure; orthostatic hypertension; orthostatic hypotension; quality of life; questionnaire; South Korea; standing; supine position; systolic blood pressure; university hospital; walking speed; blood pressure measurement; clinical trial; frail elderly; frailty; hand strength; hypertension; multicenter study; orthostatic hypotension; pathophysiology; physiology; procedures; very elderly | English | 2024 | 2024-06 | 10.1161/hypertensionaha.123.22382 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
