| ○ | ○ | Article | IDH2 regulates macrophage polarization and tumorigenesis by modulating mitochondrial metabolism in macrophages | BackgroundTargeting the tumor microenvironment represents an emerging therapeutic strategy for cancer. Macrophages are an essential part of the tumor microenvironment. Macrophage polarization is modulated by mitochondrial metabolism, including oxidative phosphorylation (OXPHOS), the tricarboxylic acid (TCA) cycle, and reactive oxygen species content. Isocitrate dehydrogenase 2 (IDH2), an enzyme involved in the TCA cycle, reportedly promotes cancer progression. However, the mechanisms through which IDH2 influences macrophage polarization and modulates tumor growth remain unknown.MethodsIn this study, IDH2-deficient knockout (KO) mice and primary cultured bone marrow-derived macrophages (BMDMs) were used. Both in vivo subcutaneous tumor experiments and in vitro co-culture experiments were performed, and samples were collected for analysis. Western blotting, RNA quantitative analysis, immunohistochemistry, and flow cytometry were employed to confirm changes in mitochondrial function and the resulting polarization of macrophages exposed to the tumor microenvironment. To analyze the effect on tumor cells, subcutaneous tumor size was measured, and growth and metastasis markers were identified.ResultsIDH2-deficient macrophages co-cultured with cancer cells were found to possess increased mitochondrial dysfunction and fission than wild-type BMDM. Additionally, the levels of M2-associated markers decreased, whereas M1-associated factor levels increased in IDH2-deficient macrophages. IDH2-deficient macrophages were predominantly M1. Tumor sizes in the IDH2-deficient mouse group were significantly smaller than in the wild-type mouse group. IDH2 deficiency in macrophages was associated with inhibited tumor growth and epithelial-mesenchymal transition.ConclusionsOur findings suggest that IDH2 deficiency inhibits M2 macrophage polarization and suppresses tumorigenesis. This study underlines the potential contribution of IDH2 expression in macrophages and tumor microenvironment remodeling, which could be useful in clinical cancer research. | Lee, Sung Woo; Kim, Soyoon; Kim, Bokyung; Seong, Jung Bae; Park, Young-Ho; Lee, Hong Jun; Choi, Dong Kyu; Yeom, Eunbyul; Lee, Dong-Seok | Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat Biores Grp, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Sch Life Sci & Biotechnol, Daegu 41566, South Korea; Illimis Therapeut Inc, Seoul 06376, South Korea; Korea Res Inst Biosci & Biotechnol KRIBB, Natl Primate Res Ctr, Cheongju 28116, South Korea; Korea Res Inst Biosci & Biotechnol KRIBB, Futurist Anim Resource & Res Ctr FARRC, Cheongju 28116, South Korea; Chungbuk Natl Univ, Coll Med & Med Res Inst, Cheongju 28644, Chungbuk, South Korea; HuMetaCELL Inc, Res Inst, 220 Bugwang Ro, Bucheon Si, Gyeonggi Do, South Korea | ; Choi, dongKyu/LKL-2959-2024; lee, wj/JNR-4926-2023 | 57939888700; 57292105000; 57205869587; 57202134219; 56246852400; 35215736300; 57215816624; 59510719100; 57210068061 | lee1@knu.ac.kr; | MOLECULAR MEDICINE | MOL MED | 1076-1551 | 1528-3658 | 30 | 1 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CELL BIOLOGY;MEDICINE, RESEARCH & EXPERIMENTAL | 2024 | 6.4 | 14.9 | 1.56 | 2025-05-07 | 2 | 4 | Isocitrate dehydrogenase 2; Mitochondria; Cancer; Tumor microenvironment; Macrophage polarization | TUMOR PROGRESSION; ACTIVATION; PROMOTES; CELLS; EMT | Cancer; Isocitrate dehydrogenase 2; Macrophage polarization; Mitochondria; Tumor microenvironment | Animals; Carcinogenesis; Cell Line, Tumor; Coculture Techniques; Humans; Isocitrate Dehydrogenase; Macrophage Activation; Macrophages; Mice; Mice, Knockout; Mitochondria; Tumor Microenvironment; 2 oxoglutaric acid; isocitrate dehydrogenase 2; isocitrate dehydrogenase; isocitrate dehydrogenase 2, mouse; animal cell; animal experiment; animal model; Article; bone marrow derived macrophage; cancer growth; cancer research; carcinogenesis; cell culture; cell function; cell fusion; cell migration assay; clonogenic assay; coculture; confocal laser scanning microscopy; controlled study; enzyme regulation; epithelial mesenchymal transition; flow cytometry; immunocytochemistry; immunohistochemistry; in vitro study; in vivo study; M1 macrophage; M2 macrophage; macrophage; male; metastasis; mitochondrial respiration; mouse; nonhuman; oxidative phosphorylation; phenotype; polarization; protein expression; real time polymerase chain reaction; RNA analysis; tumor cell; tumor microenvironment; tumor volume; Western blotting; animal; carcinogenesis; genetics; human; knockout mouse; macrophage activation; metabolism; mitochondrion; pathology; tumor cell line; tumor microenvironment | English | 2024 | 2024-09-10 | 10.1186/s10020-024-00911-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Review | Integrating Machine Learning Models with Comprehensive Data Strategies and Optimization Techniques to Enhance Flood Prediction Accuracy: A Review | The occurrence of natural disasters, accelerated by climate change, has become a continuous menace to the environment and consequently impacts the socioeconomic well-being of people. Flood events are natural disasters resulting from excessive rainfall duration, intensity, and snow melt. Flood disaster management systems that are machine learning-based have been increasingly suggested and applied to forestall the impacts of floods on the environment in terms of monitoring and warning. This study aims to critically review various studies conducted on flood management systems to identify applicable data sources and machine learning models. The study applied Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to source data from an academic database using some selected keywords, which were identified for the review process after filtering a total number of forty-two pertinent research papers was used. The review identified different combinations of flood data, flood management techniques, flood models, application of machine learning in flood predictions, optimization techniques, data processing techniques, and evaluation techniques. The study concluded that a standard approach should be applied in building robust and efficient flood disaster management systems. Lastly, informed future research directions on using machine learning for flood prediction and susceptibility mapping are provided. | Akinsoji, Adisa Hammed; Adelodun, Bashir; Adeyi, Qudus; Salau, Rahmon Abiodun; Odey, Golden; Choi, Kyung Sook | Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Univ Ilorin, Dept Agr & Biosyst Engn, PMB 1515, Ilorin 240003, Nigeria; Natl Univ Kyungpook, Inst Agr Sci & Technol, Daegu 41566, South Korea | ; Odey, Golden/MVV-6310-2025; Adelodun, Bashir/O-2941-2018 | 57775999000; 57193774482; 58672628000; 58827632400; 57211444984; 54392662900 | adisaakinsoji@knu.ac.kr;adelodun.b@unilorin.edu.ng;adeyi.qudus@knu.ac.kr;olanrewajusalau2790@gmail.com;goldenodey@knu.ac.kr;ks.choi@knu.ac.kr;adbash2008@gmail.com; | WATER RESOURCES MANAGEMENT | WATER RESOUR MANAG | 0920-4741 | 1573-1650 | 38 | 12 | SCIE | ENGINEERING, CIVIL;WATER RESOURCES | 2024 | 4.7 | 14.9 | 2.42 | 2025-05-07 | 7 | 9 | Flood prediction; Flood susceptibility; Machine learning; Optimization; Data sources | NEURAL-NETWORKS; INTERVALS | Data sources; Flood prediction; Flood susceptibility; Machine learning; Optimization | Climate change; Data handling; Disaster prevention; Disasters; Flood control; Forecasting; Information management; Machine learning; Data-source; Flood disaster management; Flood prediction; Flood susceptibility; Machine learning models; Machine-learning; Management systems; Natural disasters; Optimisations; Optimization techniques; accuracy assessment; data set; flooding; Integrated Ocean Observing System; literature review; machine learning; optimization; prediction; strategic approach; Floods | English | 2024 | 2024-09 | 10.1007/s11269-024-03885-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Microplastics, their abundance, and distribution in water and sediments in North Chennai, India: An assessment of pollution risk and human health impacts | Plastic particles, measuring <5 mm in size, mainly originate from larger plastic debris undergoing degradation, fragmenting into even smaller fragments. The goal was to analyze the spatial diversity and polymer composition of microplastics (MPs) in North Chennai, South India, aiming to evaluate their prevalence and features like composition, dimensions, color, and shape. In 60 sediment samples, a combined count of 1589 particles were detected, averaging 26 particles per 5 g-1 of dry sediment. The water samples from the North Chennai vicinity encompassed a sum of 1588 particles across 71 samples, with an average of 22 items/L. The majority of MPs ranged in size from 1 mm to 500 mu m. The ATR-FTIR results identified the predominant types of MPs as polystyrene, polyvinyl chloride, polyethylene, polyethylene terephthalate, and polypropylene in sediment and water. The spatial variation analysis revealed high MPs concentration in landfill sites, areas with dense populations, and popular tourist destinations. The pollution load index in water demonstrated that MPs had contaminated all stations. Upon evaluating the polymeric and pollution risks, it was evident that they ranged from 5.13 to 430.15 and 2.83 to 15,963.2, which is relatively low to exceedingly high levels. As the quantity of MPs and hazardous polymers increased, the level of pollution and corresponding risks also escalated significantly. The existence of MPs in lake water, as opposed to open well water, could potentially pose a cancer risk for both children and adults who consume it. Detecting MPs in water samples highlights the significance of implementing precautionary actions to alleviate the potential health hazards they create. | K.s., Vignesh; Prapanchan, V. N.; Selvan, V.

| ○ | Article | 3D-printed magnetic-based air pressure sensor for continuous respiration monitoring and breathing rehabilitation | The rapid development of point-of-care testing has made prompt diagnosis, monitoring and treatment possible for many patients suffering from chronic respiratory diseases. Currently, the biggest challenge is further optimizing testing devices to facilitate more functionalities with higher efficiency and performance, along with specificity toward patient needs. By understanding that patients with chronic respiratory diseases may have difficulty breathing within a normal range, a respiration sensor is developed focusing on sensitivities in the lower air pressure range. In contrast to the simpler airflow data, the sensor can provide respiratory air pressure as an output using a magnetic-based pressure sensor. This unconventional but highly reliable approach, combined with the rest of the simple 3D-printed design of the sensor, offers a wide range of tunability and functionalities. Due to the detachable components of the respiration sensor, the device can be easily transformed into other respiratory uses such as an inspiratory muscle training device or modified to cater for higher-ranged deep breathing. Therefore, not only does it reach very low air pressure measurement (0.1 cmH2O) for normal, tidal breathing, but the sensor can also be manipulated to detect high levels of air pressure (up to 35 cmH2O for exhalation and 45 cmH2O for inhalation). With its excellent sensitivities (0.0456 mV/cmH2O for inhalation,-0.0940 mV/cmH2O for exhalation), impressive distinction between inhalation and exhalation, and fully reproducible and convenient design, we believe that this respiration sensor will pave the way for developing multimodal and multifunctional respiration sensors within the biomedical field. © The Author(s) 2024. | Zulkifli, Nora Asyikin; Jeong, Wooseong; Kim, Mijin; Kim, Cheolgi; Ko, Young Hwii; Hyun, Dong Choon; Lee, Sungwon | Department of Physics and Chemistry, Daegu Gyeongbuk Institute of Science & Technology (DGIST), Daegu, 42988, South Korea; Department of Research and Development Strategy, Korea Institute of Materials and Science (KIMS), Changwon, 51508, South Korea; Department of Physics and Chemistry, Daegu Gyeongbuk Institute of Science & Technology (DGIST), Daegu, 42988, South Korea; Department of Physics and Chemistry, Daegu Gyeongbuk Institute of Science & Technology (DGIST), Daegu, 42988, South Korea; Department of Urology, Yeungnam University Medical Center (YUMC), Daegu, 42415, South Korea; Department of Polymer Science and Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Physics and Chemistry, Daegu Gyeongbuk Institute of Science & Technology (DGIST), Daegu, 42988, South Korea | 57223429921; 57201319474; 57207768901; 7409879273; 25723368800; 15834575400; 56976186600 | dong.hyun@knu.ac.kr;swlee@dgist.ac.kr; | Soft Science | SOFT SCI-US | N/A | 2769-5441 | 4 | 2 | ESCI | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 9 | 15.1 | 3.89 | 2025-05-07 | 13 | 3D-printing; Chronic respiratory disease; magnetic sensor; respiration sensor; tidal breathing | English | Final | 2024 | 10.20517/ss.2024.11 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | CXCL5/CXCL8 induces neutrophilic inflammation in peri-implantitis | Objective and Background: This research aimed to examine the role of C-X-C motif chemokine ligand 5 (CXCL5) and C-X-C motif chemokine ligand 8 (CXCL8; also known as IL-8) in neutrophilic inflammation triggered by peri-implantitis and to shed light on the underlying mechanisms that link them to the development of this condition. Materials: This study included 40 patients who visited the Department of Periodontology at Kyungpook University Dental Hospital. They were divided into two groups based on their condition: healthy implant (HI) group (n = 20) and peri-implantitis (PI) group (n = 20). Biopsy samples of PI tissue were collected from the patients under local anesthesia. HI tissue was obtained using the same method during the second implant surgery. To construct libraries for control and test RNAs, the QuantSeq 3 ' mRNA-Seq Library Prep Kit (Lexogen, Inc., Austria) was used according to the manufacturer's instructions. Samples were pooled based on representative cytokines obtained from RNA sequencing results and subjected to Reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Hematoxylin and eosin staining, and immunohistochemistry (IHC) analysis were performed to visually assess expression levels and analyze tissue histology. Student's t-test was employed to conduct statistical analyses. Results: Initially, heatmaps were used to examine gene expression variations between the HI and PI groups based on the results of RNA sequencing. Notably, among various cytokines, CXCL5 and CXCL8 had the highest expression levels in the PI group compared with the HI group, and they are known to be associated with inflammatory responses. In the gingival tissues, the expression of genes encoding cytokines such as interleukin (IL)-1 beta, tumor necrosis factor-alpha (TNF)-alpha, interleukin (IL)-6, and CXCL5/CXCL8 was assessed via RT-qPCR. The mRNA expression level of CXCL5/CXCL8 significantly increased in the PI group compared with the HI group (p < .045). Contrarily, the mRNA expression level of interleukin 36 receptor antagonist (IL36RN) significantly decreased (p < .008). IHC enabled examination of the distribution and intensity of CXCL5/CXCL8 protein expression within the tissue samples. Specifically, increased levels of CXCL5/CXCL8 promote inflammatory responses, cellular proliferation, migration, and invasion within the peri-implant tissues. These effects are mediated through the activation of the PI3K/Akt/NF-kappa B signaling pathway. Conclusions: This study found that the PI sites had higher gene expression level of CXCL8/CXCL5 in the soft tissue than HI sites, which could help achieve more accurate diagnosis and treatment planning. | Park, Seong-Eun; Park, Kanghyun; Kim, Eungyung; Kim, Chae Yeon; Hwang, Sung-Min; Lee, Jae-Mok; Suh, Jo-Young; Lee, Youngkyun; Kim, Myoung Ok; Kim, Yong-Gun | Kyungpook Natl Univ, Sch Dent, Dept Periodontol, 2177 Dalgubeol Daero, Daegu 41940, South Korea; Kyungpook Natl Univ, Res Inst Innovat Anim Sci, Dept Anim Sci & Biotechnol, Sangju Si 37224, Gyeongsangbuk D, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Biochem, Daegu, South Korea; Kyungpook Natl Univ, Inst Hard Tissue & Bone Regenerat, Sch Dent, Daegu, South Korea | ; Kim, Yong-Gun/JPQ-3309-2023 | 59030925600; 58530860300; 57217871658; 57966906800; 57870525500; 17346330000; 7201514992; 36062942200; 8934745900; 55622694400 | ok4325@knu.ac.kr;periokyg@knu.ac.kr; | JOURNAL OF PERIODONTAL RESEARCH | J PERIODONTAL RES | 0022-3484 | 1600-0765 | 59 | 4 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2024 | 3.4 | 15.1 | 2.47 | 2025-05-07 | 4 | 4 | cytokines; dental implants; inflammation; peri-implantitis | CREVICULAR FLUID; PEPTIDE ENA-78; EXPRESSION; CYTOKINES; DIAGNOSIS | cytokines; dental implants; inflammation; peri-implantitis | Adult; Chemokine CXCL5; Female; Humans; Inflammation; Interleukin-8; Male; Middle Aged; Neutrophils; Peri-Implantitis; CXCL5 protein, human; CXCL8 protein, human; epithelial derived neutrophil activating factor 78; interleukin 8; adult; female; human; immunology; inflammation; male; metabolism; middle aged; neutrophil; pathology; periimplantitis | English | 2024 | 2024-08 | 10.1111/jre.13230 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Comparing clinical outcomes of vitamin K antagonists vs non-vitamin K antagonists in anticoagulant therapy for mesenteric venous thrombosis | Objective: Non-vitamin K antagonist oral anticoagulants have shown similar efficacy fi cacy and lower bleeding rates than vitamin K antagonists for venous thromboembolism. However, this has not been proven in mesenteric vein thrombosis. This study aimed to compare the clinical outcomes of vitamin K antagonists and non-vitamin K antagonist oral anticoagulants. Methods: Between January 2014 and July 2022, mesenteric vein thrombosis was diagnosed on computed tomography in 225 patients in a tertiary hospital. Among them, a total of 44 patients who underwent long-term anticoagulation therapy over 3 months were enrolled in this study. Patients were divided into two groups based on the anticoagulant used: vitamin K antagonists (Group 1, n = 21) and non-vitamin K antagonist oral anticoagulants (Group 2, n = 23). The efficacy fi cacy outcomes were symptom recurrence and thrombus resolution on follow-up computed tomography, and the safety outcome was bleeding complications. Results: The median age of the patients was 56 years (range, 46-68 years), and 52% were men. The most common risk factors were unprovoked intra-abdominal infections (30%). The median duration of anticoagulation therapy was 13 months (20 months in Group 1 vs 6 months in Group 2; P = . 076). Of the 44 patients, 17 (39%) received the standard treatment. The median follow-up period was longer in Group 1 than in Group 2 (57 vs 28 months; P = . 048). No recurrence of mesenteric vein thrombosis-related symptoms were observed in either group. The median duration of follow-up computed tomography was 31 months (42 months in Group 1 vs 18 months in Group 2; P = . 064). Computed tomography revealed complete thrombus resolution, partial resolution, and no changes in 71%, 19%, and 10%, respectively (P P = . 075). Regarding bleeding complications, varix bleeding and melena developed in two patients in Group 2, and anticoagulation treatment thereafter ceased. Conclusions: Despite the short follow-up duration in the non-vitamin K antagonist oral anticoagulants group, there was no clinically significant fi cant difference in the thrombus resolution rate or bleeding complications when compared with the vitamin K antagonists group. Although research on the long-term effects of non-vitamin K antagonist oral anticoagulants in patients is limited, non-vitamin K antagonist oral anticoagulants can be considered an alternative to conventional treatments.

| ○ | ○ | Article | Elevated symmetric supercapacitor performance and simulated solar light-functioning H2O2 production using single-step fabricated 2D/2D NiAl-based LDH/CoNi-based MOF nanohybrid | Combining photocatalytic hydrogen peroxide (H2O2) production with supercapacitors offers a synergistic solution to address both solar-driven catalysis and energy storage challenges. In this connection, this study explored a novel, one-step thermal impregnation method for synthesizing a high-performance nanohybrid material. The unique combination of nickel-aluminum layered double hydroxides (NiAl-L) and Co/Ni-based metal-organic framework (CoNi-M) synergistically enhances electrochemical performance, leading to improved energy storage capacity. Interestingly, the NiAl-L/CoNi-M nanohybrid heterojunction exhibits remarkable characteristics in a three-electrode system, achieving an impressive specific capacitance of 2672.3 Fg(-1) at 1 A g(-1). It also demonstrates outstanding cyclic stability, retaining 93.6 % of its capacity even after 5000 galvanostatic charge-discharge (GCD) cycles. Moreover, the symmetrical supercapacitor device made of NiAl-L/CoNi-M demonstrates outstanding performance, sustaining 90.9 % capacity after 5000 GCD cycles, with a specific capacitance of 309.7 Fg(-1) at 1 Ag-1 and a high energy density of 43 WhKg(-1). Additionally, the synergistic combination of NiAl-L and CoNi-M enhances the photocatalytic performance, achieving an H2O2 evolution rate of 334.86 mu mol L-1 h(-1) under simulated solar light irradiation. This rate is 2.61, 3.81, and 5.81 times greater than that of pure CoNi-M, Co-M, and NiAl-L, respectively, highlighting the potential of NiAl-L/CoNi-M nanohybrid for sustainable energy application. | Husain, Ahmad; Lee, Dong-Eun; Danish, Mohtaram; Ansari, M.

| ○ | ○ | Article | Facile modification of TiO2 as S-Scheme multifunctional materials for environmental protection and energy-storage applications | This paper reports a simple one-step modification of commercial TiO2 with a conducting polytrimethoxyslilypropyl aniline (PTMSPA, a polyaniline derivative having silyl networks) to have multi-functional (photocatalytic, optical, pseudocapacitive, hydrophobic, porous, antibacterial, and electromagnetic interference shielding (EMI)) properties and demonstrates associated applications. We present the S-Scheme heterojunction (SHJ) formation between TiO2 and PTMSPA through band position alignments and designate the resultant TiO2 TiO2- based SHJ multifunctional materials as MF-TSSM. The internal electric field that is generated at the interface facilitates the transportation of the photogenerated electron transfer . The XRD pattern of MF-TSSM exhibits mainly the peaks of anatase TiO2. The TEM image of MF-TSSM indicates that the TiO2 particles are spherical in shape with sizes showing variations in diameters ranging from 60 nm to 250 nm depending on the experimental conditions of preparation and TiO2 particles are homogeneously distributed within the PTMSPA matrix. The optical energy band gap of MF-TSSM is 1.60 eV, a much lower value than PTMSPA (3.02 eV), suggesting that the composite formation between TiO2 and PTMSPA. The contact angle of MF-TSSM is significantly increased to 47.1 degrees from 8.0 of TiO2, informing the increase of hydrophobic characteristics. The rate constant (k) for methylene blue photodegradation was 0.030 min-1, and 0.010 min-1 for MF-TSSM and pristine TiO2, respectively, The MF-TSSM composite exhibits a higher specific capacitance value (28.7 F/g) than TMSPA (21.1 F/g). At a frequency of 0.42 THz, MF-TSSM and PTMSPA exhibit return loss features indicating good EMI shielding performance. The MF-TSSM has been tested against two different Gram-positive and Gram-negative bacterial strains. The nanoparticles were evaluated at doses of 10, 20, 40, and 80 mu g/ml. The results indicated that Klebsiella pneumoniae demonstrated a greater zone of inhibition, ranging from 9 mm at 10 mu g/ml to 23 mm at 80 mu g/ml, indicating increased susceptibility. Pseudomonas aeruginosa exhibited reduced inhibition zones, ranging from 10 mm at 10 mu g/ml to 14 mm at 80 mu g/ml, indicating increased resistance. The excellent effectiveness of MF-TSSM against various Gram-positive and Gram-negative pathogenic bacteria is explained by the interaction between reactive oxygen species and the cellular components of the bacteria as well the electrostatic interaction arising between positive charges in TMSPA and negative charges in the cell components, resulting in notable cytotoxicity and damage to the bacterial cells. The research underscores the capability of these modified TiO2 nanoparticles in addressing bacterial infections, with efficiency differing by bacterial strain. | Arumugam, Chandravadhana; Kannan, Venkatramanan; Karthikeyan, Vaithinathan; Theja, Vaskuri C.

| ○ | ○ | Article | Impact of Blood Pressure on Allograft Function and Survival in Kidney Transplant Recipients | The optimal target blood pressure for kidney transplant (KT) patients remains unclear. We included 808 KT patients from the KNOW-KT as a discovery set, and 1,294 KT patients from the KOTRY as a validation set. The main exposures were baseline systolic blood pressure (SBP) at 1 year after KT and time-varying SBP. Patients were classified into five groups: SBP = 140 mmHg. SBP trajectories were classified into decreasing, stable, and increasing groups. Primary outcome was composite kidney outcome of >= 50% decrease in eGFR or death-censored graft loss. Compared with the 110-119 mmHg group, both the lowest (adjusted hazard ratio [aHR], 2.43) and the highest SBP (aHR, 2.25) were associated with a higher risk of composite kidney outcome. In time-varying model, also the lowest (aHR, 3.02) and the highest SBP (aHR, 3.60) were associated with a higher risk. In the trajectory model, an increasing SBP trajectory was associated with a higher risk than a stable SBP trajectory (aHR, 2.26). This associations were consistent in the validation set. In conclusion, SBP >= 140 mmHg and an increasing SBP trajectory were associated with a higher risk of allograft dysfunction and failure in KT patients. | Kim, Hyo Jeong; Kim, Kyung Won; Joo, Young Su; Ryu, Junghwa; Jung, Hee-Yeon; Jeong, Kyung Hwan; Kim, Myung-Gyu; Ju, Man Ki; Han, Seungyeup; Lee, Jong Soo; Kang, Kyung Pyo; Ro, Han; Lee, Kyo Won; Huh, Kyu Ha; Kim, Myoung Soo; Kim, Beom Seok; Yang, Jaeseok | Gangnam Severance Hosp, Dept Internal Med, Div Nephrol, Seoul, South Korea; Korea Univ, Guro Hosp, Coll Med, Dept Internal Med, Seoul, South Korea; Yonsei Univ, Yongin Severance Hosp, Dept Internal Med, Coll Med, Yongin, South Korea; Ewha Womans Univ, Seoul Hosp, Dept Internal Med, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Daegu, South Korea; Kyung Hee Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Korea Univ, Coll Med, Anam Hosp, Dept Internal Med, Seoul, South Korea; Yonsei Univ, Gangnam Severance Hosp, Coll Med, Dept Surg, Seoul, South Korea; Keimyung Univ, Dongsan Med Ctr, Dept Internal Med, Daegu, South Korea; Ulsan Univ Hosp, Dept Internal Med, Ulsan 682714, South Korea; Jeonbuk Natl Univ, Med Sch, Res Inst Clin Med, Dept Internal Med, Jeonju, South Korea; Gachon Univ, Dept Internal Med, Gil Hosp, Incheon, South Korea; Sungkyunkwan Univ, Dept Surg, Seoul Samsung Med Ctr, Seoul, South Korea; Yonsei Univ, Severance Hosp, Coll Med, Dept Surg, Seoul, South Korea; Yonsei Univ, Severance Hosp, Coll Med, Dept Internal Med, Seoul, South Korea | ; Ju, Man/AAB-8449-2019; Kim, Su Hyun/JPY-2079-2023; Yang, Jae/LUW-8250-2024; Han, Seung Seok/HGD-2825-2022; Kim, Dong Ki/J-5389-2012; Kim, Soo-Yeon/ADR-9663-2022; Lee, Jeeyun/I-7171-2015; Jung, Hee-Yeon/AFB-8578-2022; Kang, Kyung Pyo/ABG-3614-2020 | 57476930200; 58702085600; 56453920900; 14621981000; 57196396467; 8443579300; 36183208900; 15755796200; 24281360600; 57201264463; 7402223564; 26538034700; 57196252088; 58037785900; 57991986800; 57226054292; 57212326527 | jcyjs@yuhs.ac; | TRANSPLANT INTERNATIONAL | TRANSPL INT | 0934-0874 | 1432-2277 | 37 | SCIE | SURGERY;TRANSPLANTATION | 2024 | 3 | 15.2 | 0.72 | 2025-05-07 | 1 | 1 | kidney transplantation; graft outcome; blood pressure; time-varying; trajectory | VASCULAR SMOOTH-MUSCLE; INDUCED HYPERTENSION; CARDIOVASCULAR-DISEASE; ARTERIAL-HYPERTENSION; GRAFT-SURVIVAL; CYCLOSPORINE; PATHOGENESIS; FAILURE; BP | blood pressure; graft outcome; kidney transplantation; time-varying; trajectory | Adult; Aged; Allografts; Blood Pressure; Female; Glomerular Filtration Rate; Graft Rejection; Graft Survival; Humans; Hypertension; Kidney Transplantation; Male; Middle Aged; Proportional Hazards Models; Transplant Recipients; adult; allograft; antihypertensive therapy; Article; blood pressure; body mass; cardiovascular risk; cohort analysis; controlled study; cytotoxicity; dialysis; diastolic blood pressure; estimated glomerular filtration rate; female; follow up; glomerulus filtration rate; graft recipient; graft survival; human; human tissue; incidence; kidney graft; kidney transplantation; major clinical study; male; middle aged; outcome assessment; prevalence; prospective study; renin angiotensin aldosterone system; retrospective study; risk factor; smoking; survival; systolic blood pressure; aged; allograft; glomerulus filtration rate; graft recipient; graft rejection; hypertension; proportional hazards model | English | 2024 | 2024-08-07 | 10.3389/ti.2024.12574 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Investigation of ZnO@CdS nanocomposite with amplified photocatalytic H2 production under visible light irradiation | Researchers are trying to develop an efficient solar-powered catalytic water splitting system to solve the energy dilemma and generate green hydrogen. In this study, ZnO@CdS nano-heterostructures were synthesized using sol-gel and co-precipitation techniques. The pristine ZnO, CdS, and their heterostructures were characterized through various characterization tools such as XRD, SAED, XPS, FTIR, EDX, SEM, FE-TEM, UV-vis, MottSchottky, GCG, EIS, and PL, to know the crystal structure, chemical state, elemental composition, morphology, band gap, scheme mechanism, hydrogen production and charge transfer resistance characteristics of the samples, respectively. The SEM, FE-TEM, confirm that CdS NPs are well decorated on hexagonal ZnO rods. The efficient H-2 production of 587.86 mu molg(-1) h(-1) were measured for the optimized sample which is 3.91 times greater than pure ZnO rods and 3.22 times than CdS NPs. Strong photo-cyclic stability test was carried out for 20 h in four cycles while, PL spectroscopy confirms the suppressed charge recombination. All of the above characterization prove that (ZC-20) optimized sample, has a potential to be used as an efficient and stable photocatalyst for H-2 production via photocatalytic water splitting. | Ali, Asim; Ali, Sardar; Zulfiqar, Syed; Kang, Kyeong Tae; Khan, Tahirzeb; Khattak, Shaukat; Khan, Gulzar; Rahman, Muneeb Ur; Shaik, Mohammed Rafi | Abdul Wali Khan Univ Mardan, Dept Phys, Kpk 23200, Pakistan; Kyungpook Natl Univ, Dept Phys, KNU G LAMP Project Grp, Daegu 41566, South Korea; Islamia Coll Peshawar, Dept Phys, Peshawar 25000, Kpk, Pakistan; King Saud Univ, Coll Sci, Dept Chem, POB 2455, Riyadh 11451, Saudi Arabia | Rahman, Prof. Dr. Muneeb/AAK-1878-2020; Zulfiqar, Syed/AAR-2955-2021; khan, Tahirzeb/GWR-1022-2022; Shaik, Prof. Mohammed Rafi/N-8161-2014; Khattak, Shaukat/P-7453-2019 | 58269655200; 57709569800; 57201063392; 56002123900; 57193418637; 57200182393; 57203663638; 8218064000; 55098241300 | sydzlfqr@awkum.edu.pk;ktkang@knu.ac.kr; | SURFACES AND INTERFACES | SURF INTERFACES | 2468-0230 | 52 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, COATINGS & FILMS;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 6.3 | 15.2 | 2.12 | 2025-05-07 | 9 | 9 | Heterostructure; Water splitting; H-2 generation; Photocatalyst; ZnO@CdS | ENHANCED HYDROGEN EVOLUTION; STEP HYDROTHERMAL SYNTHESIS; CHARGE SEPARATION; WATER; HETEROSTRUCTURES; NANOSTRUCTURES; FABRICATION; COMPOSITE | H<sub>2</sub> generation; Heterostructure; Photocatalyst; Water splitting; ZnO@CdS | English | 2024 | 2024-09 | 10.1016/j.surfin.2024.104836 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Risk factors for urinary retention after robot-assisted radical cystectomy with orthotopic neobladder diversion: a multicenter study | To determine risk factors for urinary retention (UR) after robot-assisted radical cystectomy (RALC) with orthotopic neobladder diversion. A total of 269 patients who underwent RALC with orthotopic neobladder diversion from 2008 to 2019 at seven tertiary hospitals were retrospectively analyzed. There were 68 patients who had UR (UR arm) and 201 patients who did not have UR (no-UR arm). UR was defined as voiding dysfunction without catheterization or more than 100 mL of residual urine after voiding. Preoperative demographics, perioperative factors, pathology outcomes, and postoperative complications of UR and no-UR arms were compared and predictors of UR were identified. Among demographic factors, only gender proportion showed a difference, with male proportion being significantly lower in the UR arm than in the no-UR arm (81% vs 92%, p = 0.010). For perioperative outcomes, anastomosis site stricture (27% vs 11%, p = 0.003) and length of hospital stays (23 days vs. 19 days, p = 0.001) were significantly higher in the UR arm than in the no-UR arm. In multiple logistic regression analysis, female (OR 3.32, 95% CI: 1.43-7.72) and body mass index (BMI) (OR 1.10, 95% CI 1.00-1.20) were UR predictors. UR after RALC with orthotopic neobladder diversion is significantly increased in females. Multiple logistic regression analysis identified female and BMI elevation as UR predictors. | Chung, Younsoo; Lee, Sangchul; Jeong, Byong Chang; Ku, Ja Hyeon; Kwon, Tae Gyun; Kim, Tae-Hwan; Lee, Ji Youl; Hong, Sung Hoo; Han, Woong Kyu; Ham, Won Sik; Kang, Sung Gu; Kang, Seok Ho; Oh, Jong Jin | Seoul Natl Univ, Bundang Hosp, Dept Urol, Seongnam, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Sch Med, Dept Urol, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Urol, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Urol, Daegu, South Korea; Catholic Univ Korea, Coll Med, Seoul St Marys Hosp, Dept Urol, Seoul, South Korea; Yonsei Univ, Coll Med, Severance Hosp, Dept Urol, Seoul, South Korea; Korea Univ, Coll Med, Dept Urol, Seoul, South Korea; Bldg 17th floor Urol Off,300-0, Seongnam Si, Gyeonggi Do, South Korea | ; Ku, Ja/J-5377-2012 | urojin@snu.ac.kr; | JOURNAL OF ROBOTIC SURGERY | J ROBOT SURG | 1863-2483 | 1863-2491 | 19 | 1 | SCIE | SURGERY | 2024 | 3 | 15.2 | 0 | Bladder cancer; Body mass index; Female; Urination; Urination disorder | BODY-MASS INDEX; ILEAL NEOBLADDER; VOIDING DYSFUNCTION; BLADDER SUBSTITUTION; EXPERIENCE; WOMEN | English | 2024 | 2024-11-16 | 10.1007/s11701-024-02099-y | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Verifying the physical role of upper-active-layer on charge transport together with bias stability in bilayer-channel oxide thin-film transistors | In this work, we report the fabrication of solution-processed bilayer-structure oxide thin-film transistors (TFTs) exhibiting superior electrical characteristics and enhanced positive/negative bias stabilities. This was achieved by tuning the carrier concentration and bandgap of the top active layer in the bilayer semiconductor. The characteristics of the top layer were modulated through aluminum (Al) doping in indium oxide semiconductors. Bilayer-channel TFTs with an optimized indium-aluminum-oxide top layer (In:Al ratio of 8:2) demonstrated effective electron transport via percolation conduction and exhibited high mobility. Furthermore, the optimized bilayer TFTs displayed small threshold voltage shifts under positive and negative bias stress, attributed to the effective formation of a quasi-two-dimensional electron gas and the suppression of oxygen vacancies. An in-depth study on engineering the carrier concentration and bandgap of the bilayer structure provides insights into material design and fabrication strategies for high-performance and stable heterostructure transistors. | Lee, Jinuk; Eun, Jun-Su; Na, Jeong-Hyeon; Park, Won; Park, Jun-Hyeong; Feng, Junhao; Jang, Jaewon; Kang, In Man; Park, Jaehoon; Zhang, Xue; Kim, Do-Kyung; Bae, Jin-Hyuk | Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Hallym Univ, Sch Semicond Display Technol, Chunchon 24252, South Korea; Shandong Univ Sci & Technol, Coll Ocean Sci & Engn, Qingdao 266590, Peoples R China; LG Display, Paju 10845, South Korea | Feng, Junhao/KZF-5875-2024 | 58487758300; 58493099200; 57192006339; 58494046100; 57454302100; 57905127500; 57194107504; 7203062678; 55717156300; 55949859900; 57984042900; 35326180700 | kdk7362@knu.ac.kr;jhbae@ee.knu.ac.kr; | SURFACES AND INTERFACES | SURF INTERFACES | 2468-0230 | 51 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, COATINGS & FILMS;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 6.3 | 15.2 | 0 | 2025-05-07 | 0 | 0 | Thin-film transistors; Oxide semiconductor; Bilayer structure; Charge transport characteristics; Bias stability; Carrier concentration engineering | IMPROVED ELECTRICAL PERFORMANCE; PHOTOCHEMICAL ACTIVATION | Bias stability; Bilayer structure; Carrier concentration engineering; Charge transport characteristics; Oxide semiconductor; Thin-film transistors | English | 2024 | 2024-08 | 10.1016/j.surfin.2024.104624 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Analysis of Multiuser Diversity Gain Achieved by MIMO Systems Through User Scheduling Based on Limited Feedback in Dense Cellular Networks | We examine the sum rate of multiple-input multiple-output broadcast channels in which the locations of base stations (BS) and users follow independent homogeneous Poisson point processes. Each BS schedules appropriate users for spatial multiplexing based on partial channel state information provided by users. In this scenario, we develop a suitable channel quality information (CQI) for user scheduling, which attains a nearly optimal multiuser diversity gain. Using the proposed CQI, we determine the growth rate of the sum rate achieved with limited feedback in densely populated cellular environments. In comparison to the single-cell scenario, the growth rate is slightly diminished due to inter-cell interference caused by the dense BS topology. Nevertheless, we demonstrate that the gap in net sum spectral efficiencies achieved through user scheduling with the proposed CQI remains significantly large, even within dense cellular networks, provided that each BS can employ the optimal number of feedback bits. Thus, we also investigate the optimal feedback rate that maximizes the net sum spectral efficiency. | Kong, Jae-Ik; Min, Moonsik | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | 58487885900; 55386299100 | te04034@knu.ac.kr;msmin@knu.ac.kr; | IEEE WIRELESS COMMUNICATIONS LETTERS | IEEE WIREL COMMUN LE | 2162-2337 | 2162-2345 | 13 | 1 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 5.5 | 15.3 | 0.78 | 2025-04-16 | 2 | 2 | MIMO; user scheduling; multiuser diversity; stochastic geometry; limited feedback | STOCHASTIC GEOMETRY; WIRELESS NETWORKS; CHANNELS; DESIGN | limited feedback; MIMO; multiuser diversity; stochastic geometry; user scheduling | Channel state information; Communication channels (information theory); Geometry; MIMO systems; Random processes; Stochastic models; Stochastic systems; Wireless networks; Cellular network; Channel quality informations; Diversity method; Limited feedback; Multiuser diversity; Multiusers; Spectral efficiencies; Stochastic geometry; Symmetric matrices; User scheduling; Spectrum efficiency | English | 2024 | 2024-01 | 10.1109/lwc.2023.3322164 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Analysis of the Optimal Feedback Rate for Limited Feedback-Based Block Diagonalization in Cellular MU-MIMO Systems | We examine a downlink cellular network utilizing multiple-antenna base stations (BSs) deployed via a homogeneous Poisson point process. Each BS serves multiple users concurrently using spatial division multiple access (SDMA), with each user equipped with multiple receive antennas. The downlink SDMA employs linear precoding, specifically block diagonalization (BD), with channel state information obtained through limited feedback to construct BD precoding matrices. We offer close approximations for the optimal feedback rate aimed at maximizing the net spectral efficiency, which quantifies the net data rate achieved through limited-feedback-based BD. To achieve this, we introduce a novel lower bound for the Laplace transform of multi-cell interference. This analytical result aids in deriving the optimal feedback rate and the corresponding maximum net spectral efficiency. In comparison to previous studies that assumed single-antenna users, limited-feedback-based BD, enhanced by optimized feedback rates, substantially improves net sum spectral efficiency in interference-limited cellular networks. This result is remarkable as it holds true even with a reduced feedback bit requirement per data stream. | Lee, Sungmin; Min, Moonsik | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | 57976218200; 55386299100 | armiche96@knu.ac.kr;msmin@knu.ac.kr; | IEEE WIRELESS COMMUNICATIONS LETTERS | IEEE WIREL COMMUN LE | 2162-2337 | 2162-2345 | 13 | 2 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 5.5 | 15.3 | 0.7 | 2025-05-07 | 1 | 2 | Receiving antennas; Cellular networks; Precoding; Spectral efficiency; Multiaccess communication; Downlink; Base stations; MU-MIMO; stochastic geometry; limited feedback; block diagonalization; cellular network | block diagonalization; cellular network; limited feedback; MU-MIMO; stochastic geometry | Base stations; Channel state information; Laplace transforms; MIMO systems; Receiving antennas; Space division multiple access; Stochastic systems; Wireless networks; Block diagonalization; Cellular network; Downlink; Limited feedback; MU-MIMO; Multiaccess communication; Precoding; Spectral efficiencies; Stochastic geometry; Spectrum efficiency | English | 2024 | 2024-02 | 10.1109/lwc.2023.3332953 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
