| ○ | ○ | Article | Comparative quantifications and morphological monitoring of the topical treatment approach for onychomycosis-affected in vivo toenail using optical coherence tomography: A case study | Onychomycosis is one of the most common toenail fungal infections that affect the quality of life of many patients. Long-term and noninvasive monitoring of morphological changes of onychomycosis-affected nail plate aids the medication process and provides comfort for patients. However, existing medical and dermatological imaging methods have various types of limitations in nail investigation due to low resolution, lack of volumetric data, the necessity of highly trained personnel for image analysis, and the variety of protocols. In this study, qualitative monitoring-based quantitative assessments were performed to assess the morphological changes of onychomycosis-affected toenail for 15 consecutive weeks using high-resolution optical coherence tomography (OCT). Layer intensity and surface roughness measuring algorithms were applied to two-dimensional OCT crosssectional images to detect gradual changes in the morphological structure of the diseased toenail. A depth intensity profile and the angle formed between the nail plate and nail fold were also used to analyze the thickness and shape of the toenail plates, respectively. The quantitative and morphological monitoring results revealed significant changes in the toenail structure before and during the treatment process, confirming the healing of the diseased toenail. Therefore, the proposed noninvasive optical analysis approach can be applied to monitor nail abnormalities and evaluate the process of diseased toenail medication. | Abu Saleah, Sm; Gu, Youngae; Wijesinghe, Ruchire Eranga; Seong, Daewoon; Cho, Hoseong; Jeon, Mansik; Kim, Jeehyun | Kyungpook Natl Univ, ICT Convergence Res Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll IT Engn, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea; Sri Lanka Inst Informat Technol, Fac Engn, Dept Elect & Elect Engn, Malabe, Sri Lanka | Wijesinghe, Ruchire/K-3797-2016 | 57218499446; 58243822800; 56018152300; 57212512353; 57209416599; 24171094000; 7601373350 | msjeon@knu.ac.kr; | BIOMEDICAL SIGNAL PROCESSING AND CONTROL | BIOMED SIGNAL PROCES | 1746-8094 | 1746-8108 | 88 | SCIE | ENGINEERING, BIOMEDICAL | 2024 | 4.9 | 25.4 | 1.18 | 2025-05-07 | 3 | 3 | Onychomycosis; Optical coherence tomography; Surface roughness; Toenail monitoring; Tinea unguium | HIGH-FREQUENCY ULTRASOUND; DERMATOPHYTE ONYCHOMYCOSIS; CONFOCAL MICROSCOPY; NAIL THICKNESS; SKIN-CANCER; DIAGNOSIS; TOOL; PSORIASIS; OCT; DERMOSCOPY | Onychomycosis; Optical coherence tomography; Surface roughness; Tinea unguium; Toenail monitoring | Medical imaging; Optical tomography; Plates (structural components); Volumetric analysis; Case-studies; Fungal infection; In-vivo; Morphological changes; Nail plate; Onychomycosis; Quality of life; Tinea unguium; Toenail monitoring; Topical treatments; algorithm; Article; comparative study; controlled study; healing; human; in vivo study; onychomycosis; qualitative analysis; quantitative analysis; spectral domain optical coherence tomography; surface property; thickness; tissue structure; toe nail; topical treatment; Surface roughness | English | 2024 | 2024-02 | 10.1016/j.bspc.2023.105648 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Identification and risk classification of thymic epithelial tumors using 3D computed tomography images and deep learning models | Thymic epithelial tumor (TET) is the most common neoplasm of the anterior mediastinum, accounting for approximately 47 % of all anterior mediastinal tumors. Early identification and risk stratification of patients with TET are beneficial for efficient intervention, but identifying subjects at high risk is challenging and timeconsuming. This study proposes a deep-learning (DL) framework that combines the automatic segmentation of lung lesions with the classification of high-risk cases of TET. The model was trained, validated, and tested using computed tomography images of 125 patients with TET. Our method comprises two steps: 1) automatic segmentation of TET and comparison of the performance of 3D U-Net, 3D Res U-Net, 3D Dense U-Net, 3D Wide UNet, and 3D U-Net++ models; 2) identification of high-risk TET cases using pretrained DL models (3D ResNet50, 3D SE ResNext50, 3D DenseNet121, and 3D VGG19) with transfer learning. The hyperparameters for segmentation and classification were determined using Bayesian optimization. Among the abovementioned 3D U-Netbased methods, 3D U-Net++ showed the best segmentation performance on the test set. Among the four classification models, ResNet50 performed the best on the test set. We also used a gradient-weighted class activation map to visualize the classification of risk groups in convolutional neural networks (CNNs), emphasizing sensitive features in the learning process. This study is the first to integrate automated segmentation of TETs with the identification of high-risk cases. The results demonstrate that CNN DL techniques can be used for the diagnosis and classification of risk groups in patients with TET. | Moon, Ye Sung; Park, Byunggeon; Park, Jongmin; Ho, Thao Thi; Lim, Jae-Kwang; Choi, Sanghun | Kyungpook Natl Univ, Sch Mech Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ Hosp, Dept Radiol, Sch Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea | Choi, Sanghun/AGS-7430-2022; Moon, Yesung/MIO-6443-2025 | 59138962200; 57211532915; 57216463879; 59138790200; 55515341400; 55847101000 | limjk@knu.ac.kr;s-choi@knu.ac.kr; | BIOMEDICAL SIGNAL PROCESSING AND CONTROL | BIOMED SIGNAL PROCES | 1746-8094 | 1746-8108 | 95 | SCIE | ENGINEERING, BIOMEDICAL | 2024 | 4.9 | 25.4 | 1.18 | 2025-05-07 | 2 | 3 | Machine learning; Transfer learning; Bayesian Optimization; Convolutional neural network; Artificial intelligence | MASAOKA-KOGA STAGE; THYMOMA | Artificial intelligence; Bayesian Optimization; Convolutional neural network; Machine learning; Transfer learning | Classification (of information); Computer aided diagnosis; Computerized tomography; Convolutional neural networks; Deep learning; Image classification; Learning systems; Patient treatment; Transfer learning; Automatic segmentations; Bayesian optimization; Classification of risk; Computed tomography images; Convolutional neural network; Learning models; Machine-learning; Risk groups; Test sets; Transfer learning; adult; area under the curve; Article; cohort analysis; computer assisted tomography; controlled study; convolutional neural network; deep learning; diagnostic accuracy; diagnostic test accuracy study; female; high risk population; human; image segmentation; major clinical study; male; middle aged; receiver operating characteristic; retrospective study; sensitivity and specificity; thymic epithelial neoplasm; transfer of learning; tumor classification; Tumors | English | 2024 | 2024-09 | 10.1016/j.bspc.2024.106473 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Synthesis of Double Benzimidazole-Fused Quinazolines and Pyrimidines Catalyzed by Recyclable Magnetic Cu-MOF-74 | 2-(2-Bromoaryl)- and 2-(2-bromovinyl)benzimidazoles are combined and cyclized with benzimidazoles using a catalytic amount of magnetic Cu-MOF-74 (Fe3O4@SiO2@Cu-MOF-74) and a base under O2 atmosphere, yielding the corresponding double benzimidazole-fused quinazolines and pyrimidines. The catalyst can be recovered using a magnetic bar and reused multiple times without significant loss of catalytic activity. The reaction mechanism likely involves the initial formation of a C-N coupled intermediate through nucleophilic aromatic substitution, followed by oxidative cyclization. | Lee, Seong Weon; Dao, Pham Duy Quang; Cho, Chan Sik | Kyungpook Natl Univ, Dept Appl Chem, 80 Daehakro, Daegu 41566, South Korea; Vietnam Acad Sci & Technol, Inst Appl Mat Sci, Ho Chi Minh City 700000, Vietnam | ; Dao, P.

| ○ | ○ | Article | Using beat score maps with successive segmentation for ECG classification without R-peak detection | As a primary indicator for cardiovascular diseases, the electrocardiogram (ECG) is commonly used for arrhythmia classification. Many related studies emphasize that the R-peaks of the ECG signal are essential for extracting features or signal segmentation. Thus, the chosen R-peak detection algorithm affects classification performance. Furthermore, the lack of distinct R-peaks in arrhythmias like ventricular flutter makes these rhythms difficult to identify, regardless of the detection algorithm. Therefore, this study proposes a novel ECG rhythm classification framework that does not depend on R-peak detection. First, the n number of beat segments is acquired by sliding a window over the ECG signal. A scalogram is then produced from each segment and fed into a pre-trained beat classifier to generate n beat score vectors. These vectors are concatenated chronologically to establish an n-beat score map (n-BSM), which serves as input for our rhythm classification model. The n-BSM of a rhythm conveys information regarding its constituent n beats by sequentially arranging their characteristics, each captured by a score distribution over various beat types. Experimental results from the MIT-BIH arrhythmia database (MITDB) demonstrate that the proposed method improves overall performance in classifying ten ECG rhythms. Moreover, we achieved a 97.56% F1 score for a ventricular flutter rhythm lacking distinct R-peaks. We also utilized the MIT-BIH Malignant Ventricular Ectopy (VFDB) and the Chapman-Shaoxing 12-lead ECG databases (SPH) to verify the proposed method's robustness and generalizability. The average accuracy for different rhythms was 99.28% and 88.83%, respectively. | Lee, Jaewon; Shin, Miyoung | Kyungpook Natl Univ, Sch Elect & Elect Engn, Biointelligence & Data Min Lab, Daegu 41566, South Korea | 58377059800; 7401536642 | shinmy@knu.ac.kr; | BIOMEDICAL SIGNAL PROCESSING AND CONTROL | BIOMED SIGNAL PROCES | 1746-8094 | 1746-8108 | 91 | SCIE | ENGINEERING, BIOMEDICAL | 2024 | 4.9 | 25.4 | 2.76 | 2025-05-07 | 7 | 8 | Arrhythmia; ECG; Successive segmentation; N-BSM; Deep learning | ARRHYTHMIA DETECTION; CARDIAC-ARRHYTHMIAS; ATRIAL-FIBRILLATION; CNN | Arrhythmia; Deep learning; ECG; N-BSM; Successive segmentation | Classification (of information); Deep learning; Diseases; Flutter (aerodynamics); Signal detection; Arrhythmia; Arrhythmia classification; Cardiovascular disease; Deep learning; Detection algorithm; Electrocardiogram signal; Extracting features; N-BSM; R-peak detection; Successive segmentation; Article; cardiovascular disease; classification; continuous wavelet transform; controlled study; deep learning; detection algorithm; discrete wavelet transform; electrocardiogram; electrocardiography; heart arrhythmia; heart ventricle flutter; human; principal component analysis; QRS complex; QRS interval; sinus bradycardia; supraventricular tachycardia; Electrocardiograms | English | 2024 | 2024-05 | 10.1016/j.bspc.2024.105982 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Anti-Inflammatory Flavonoids from Agrimonia pilosa Ledeb: Focusing on Activity-Guided Isolation | To elucidate the anti-inflammatory properties and constituents of Agrimonia pilosa Ledeb. (A. pilosa), a comprehensive investigation was conducted employing activity-guided isolation. The anti-inflammatory effects were evaluated through an in vitro nitric oxide (NO) assay on lipopolysaccharide (LPS)-treated RAW 264.7 macrophage cells. Seven bio-active compounds with anti-inflammatory properties were successfully isolated from the butanol fraction and identified as follows: quercetin-7-O-beta-d-rhamnoside (1), apigenin-7-O-beta-d-glucopyranoside (2), kaempferol-7-O-beta-d-glucopyranoside (3), quercetin (4), kaempferol (5), apigenin (6), and apigenin-7-O-beta-d-glucuronide-6"-butylester (7). All isolated compounds showed strong NO inhibitory activity with IC50 values ranging from 1.4 to 31 mu M. Compound 6 demonstrated the most potent NO inhibition. Compound 7, a rare flavonoid, was discerned as a novel anti-inflammatory agent, ascertained through its inaugural demonstration of nitric oxide inhibition. Subsequently, a comprehensive structure-activity relationship (SAR) analysis was conducted employing eight flavonoids derived from A. pilosa. The outcomes elucidated that flavones exhibit superior NO inhibitory effects compared to flavonols, and the aglycone form manifests greater potency in NO inhibition than the glycone counterpart. These results highlight A. pilosa as a promising source of effective anti-inflammatory agents and indicate its potential as a health-beneficial dietary supplement and therapeutic material. | Park, Mijin; Ryu, Dahye; Cho, Jwayeong; Ku, Kang-Mo; Kang, Young-Hwa | Kyungpook Natl Univ, Coll Agr & Life Sci, Dept Hort Sci, Daegu 41566, South Korea; Korea Univ, Dept Plant Biotechnol, Seoul 02841, South Korea; Korea Inst Sci & Technol KIST, Smart Farm Res Ctr, Kangnung 25451, South Korea; Korea Univ Sci & Technol UST, KIST Sch, Div Biomed Sci & Technol, Daejeon 34113, South Korea | ; Ku, Kang/AFM-3509-2022 | 56319353100; 57204860688; 57204858003; 58729600300; 56423929300 | mj-7311@hanmail.net;dahyeryu0507@hanmail.net;chocho7023@kist.re.kr;ku_km@korea.ac.kr;youngh@knu.ac.kr; | MOLECULES | MOLECULES | 1420-3049 | 29 | 2 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2024 | 4.6 | 25.5 | 0 | 2025-04-16 | 2 | 1 | Agrimonia pilosa; anti-inflammatory compounds; bioactivity-guided isolation; nitric oxide inhibitory activity | PROTEIN-TYROSINE-PHOSPHATASE; NITRIC-OXIDE; CONSTITUENTS; GLYCOSIDES; ELUCIDATION; ISOCOUMARIN; APIGENIN; TANNINS | Agrimonia pilosa; anti-inflammatory compounds; bioactivity-guided isolation; nitric oxide inhibitory activity | Agrimonia; Anti-Inflammatory Agents; Flavonoids; Kaempferols; Nitric Oxide; Quercetin; antiinflammatory agent; flavonoid; kaempferol derivative; nitric oxide; quercetin; Agrimonia | English | 2024 | 2024-01 | 10.3390/molecules29020283 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Review | Can Plant Extracts Help Prevent Hair Loss or Promote Hair Growth? A Review Comparing Their Therapeutic Efficacies, Phytochemical Components, and Modulatory Targets | This narrative review aims to examine the therapeutic potential and mechanism of action of plant extracts in preventing and treating alopecia (baldness). We searched and selected research papers on plant extracts related to hair loss, hair growth, or hair regrowth, and comprehensively compared the therapeutic efficacies, phytochemical components, and modulatory targets of plant extracts. These studies showed that various plant extracts increased the survival and proliferation of dermal papilla cells in vitro, enhanced cell proliferation and hair growth in hair follicles ex vivo, and promoted hair growth or regrowth in animal models in vivo. The hair growth-promoting efficacy of several plant extracts was verified in clinical trials. Some phenolic compounds, terpenes and terpenoids, sulfur-containing compounds, and fatty acids were identified as active compounds contained in plant extracts. The pharmacological effects of plant extracts and their active compounds were associated with the promotion of cell survival, cell proliferation, or cell cycle progression, and the upregulation of several growth factors, such as IGF-1, VEGF, HGF, and KGF (FGF-7), leading to the induction and extension of the anagen phase in the hair cycle. Those effects were also associated with the alleviation of oxidative stress, inflammatory response, cellular senescence, or apoptosis, and the downregulation of male hormones and their receptors, preventing the entry into the telogen phase in the hair cycle. Several active plant extracts and phytochemicals stimulated the signaling pathways mediated by protein kinase B (PKB, also called AKT), extracellular signal-regulated kinases (ERK), Wingless and Int-1 (WNT), or sonic hedgehog (SHH), while suppressing other cell signaling pathways mediated by transforming growth factor (TGF)-beta or bone morphogenetic protein (BMP). Thus, well-selected plant extracts and their active compounds can have beneficial effects on hair health. It is proposed that the discovery of phytochemicals targeting the aforementioned cellular events and cell signaling pathways will facilitate the development of new targeted therapies for alopecia. | Choi, Joon Yong; Boo, Min Young; Boo, Yong Chool | Kyungpook Natl Univ, Grad Sch, Dept Biomed Sci, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, BK21 Plus KNU Biomed Convergence Program, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Ppeum Clin Daegu, 39 Dongseong Ro, Daegu 41937, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Lapivu Co Ltd, 115 Dongdeok Ro, Daegu 41940, South Korea | 57576409100; 59145028800; 6602899130 | halo134679@knu.ac.kr;qnalsdud96@gmail.com;ycboo@knu.ac.kr; | MOLECULES | MOLECULES | 1420-3049 | 29 | 10 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2024 | 4.6 | 25.5 | 1.54 | 2025-05-07 | 15 | 19 | alopecia; baldness; natural product; dermal papilla; hair follicle; hair cycle; cell signaling pathway; animal model; clinical study | DERMAL PAPILLA CELLS; IN-VIVO; DOUBLE-BLIND; ANDROGENETIC ALOPECIA; TOPICAL APPLICATION; HERBAL EXTRACT; LEAVES EXTRACT; FOLLICLE; PLACEBO; APOPTOSIS | alopecia; animal model; baldness; cell signaling pathway; clinical study; dermal papilla; hair cycle; hair follicle; natural product | Alopecia; Animals; Cell Proliferation; Hair; Hair Follicle; Humans; Phytochemicals; Plant Extracts; phytochemical; plant extract; alopecia; animal; cell proliferation; chemistry; drug effect; drug therapy; growth, development and aging; hair; hair follicle; human; metabolism; prevention and control | English | 2024 | 2024-05 | 10.3390/molecules29102288 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Characteristics of the Discoloration Switching Phenomenon of 4H-SiC Single Crystals Grown by PVT Method Using ToF-SIMS and Micro-Raman Analysis | The discoloration switching appearing in the initial and final growth stages of 4H-silicon carbide (4H-SiC) single crystals grown using the physical vapor transport (PVT) technique was investigated. This phenomenon was studied, investigating the correlation with linear-type micro-pipe defects on the surface of 4H-SiC single crystals. Based on the experimental results obtained using time-of-flight secondary ion mass spectrometry (ToF-SIMS) and micro-Raman analysis, it was deduced that the orientation of the 4H-SiC c-axis causes an axial change that correlates with low levels of carbon. In addition, it was confirmed that the incorporation of additional elements and the concentrations of these doped impurity elements were the main causes of discoloration and changes in growth orientation. Overall, this work provides guidelines for evaluating the discoloration switching in 4H-SiC single crystals and contributes to a greater understanding of this phenomenon. | Kim, Seul-Ki; Kim, Hajun; Kim, Hyun Sik; Hong, Tae Eun; Lee, Younki; Jung, Eun Young | Korea Inst Ceram Engn & Technol, Semicond Mat Ctr, Jinju 52851, South Korea; Gyeongsang Natl Univ, Dept Mat Engn, Jinju 52828, South Korea; Gyeongsang Natl Univ, Dept Mat Engn & Convergence Technol, Jinju 52828, South Korea; Korea Inst Ceram Engn & Technol, Anal & Stand Ctr, Jinju 52851, South Korea; Korea Basic Sci Inst, Div High Technol Mat Res, Busan 46742, South Korea; Kyungpook Natl Univ, Inst Elect Technol, Coll IT Engn, Daegu 41566, South Korea | 57640906000; 59616432200; 34769827400; 19337084900; 36026699600; 57203199724 | skkim@kicet.re.kr;khj42021@gmail.com;hyunkim@kicet.re.kr;tehong@kbsi.re.kr;ylee@gnu.ac.kr;eyjung@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 17 | 5 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 3.2 | 25.5 | 0.33 | 2025-05-07 | 1 | 1 | 4H-SiC single crystal; physical vapor transport (PVT); discoloration switching; ToF-SIMS; Raman spectroscopy | 4H-SiC single crystal; discoloration switching; physical vapor transport (PVT); Raman spectroscopy; ToF-SIMS | Crystal impurities; Discoloration; Organic polymers; Secondary ion mass spectrometry; Silicon carbide; 4H silicon carbide; 4h-silicon carbide single crystal; Discoloration switching; Growth stages; Micro-Raman analysis; Physical vapor transport; Switching phenomenon; Time of flight secondary ion mass spectrometry; Vapor transport methods; Single crystals | English | 2024 | 2024-03 | 10.3390/ma17051005 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Design and Synthesis of Novel Indole Ethylamine Derivatives as a Lipid Metabolism Regulator Targeting PPARα/CPT1 in AML12 Cells | Peroxisome proliferator-activated receptor alpha (PPAR alpha) and carnitine palmitoyltransferase 1 (CPT1) are important targets of lipid metabolism regulation for nonalcoholic fatty liver disease (NAFLD) therapy. In the present study, a set of novel indole ethylamine derivatives (4, 5, 8, 9) were designed and synthesized. The target product (compound 9) can effectively activate PPAR alpha and CPT1a. Consistently, in vitro assays demonstrated its impact on the lipid accumulation of oleic acid (OA)-induced AML12 cells. Compared with AML12 cells treated only with OA, supplementation with 5, 10, and 20 mu M of compound 9 reduced the levels of intracellular triglyceride (by 28.07%, 37.55%, and 51.33%) with greater inhibitory activity relative to the commercial PPAR alpha agonist fenofibrate. Moreover, the compound 9 supplementations upregulated the expression of hormone-sensitive triglyceride lipase (HSL) and adipose triglyceride lipase (ATGL) and upregulated the phosphorylation of acetyl-CoA carboxylase (ACC) related to fatty acid oxidation and lipogenesis. This dual-target compound with lipid metabolism regulatory efficacy may represent a promising type of drug lead for NAFLD therapy. | Liu, Yu-Chen; Wei, Gang; Liao, Zhi-Qiang; Wang, Fang-Xin; Zong, Chunxiao; Qiu, Jiannan; Le, Yifei; Yu, Zhi-Ling; Yang, Seo Young; Wang, Heng-Shan; Dou, Xiao-Bing; Wang, Cai-Yi | Zhejiang Chinese Med Univ, Coll Life Sci, Hangzhou 310053, Peoples R China; Guangxi Normal Univ, Collaborat Innovat Ctr Guangxi Ethn Med, State Key Lab Chem & Mol Engn Med Resources, Sch Chem & Pharmaceut Sci,Minist Educ China,Key La, Guilin 541004, Peoples R China; Hong Kong Baptist Univ, Sch Chinese Med, Hong Kong, Peoples R China; Kyungpook Natl Univ, Teachers Coll, Dept Biol Educ, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Phylogen & Evolut, Daegu 41566, South Korea | wang, heng/MFH-9731-2025; Liao, Zhiqiang/HJH-2976-2023 | 57265106600; 57999335300; 58804459900; 58786939300; 57802930500; 57220870209; 57211477752; 55618252700; 57215036954; 57211472383; 8933969300; 57202550930 | 17774008010@163.com;wei18249913020@163.com;15077302639@163.com;wangfx@mailbox.gxnu.edu.cn;z1c10x1@163.com;qjntcm@163.com;lyf19970605@foxmail.com;zlyu@hkbu.edu.hk;syy@knu.ac.kr;whengshan@163.com;cloudwater@zcmu.edu.cn;wangcaiyiamy@163.com; | MOLECULES | MOLECULES | 1420-3049 | 29 | 1 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2024 | 4.6 | 25.5 | 1.44 | 2025-04-16 | 4 | 3 | NAFLD; PPAR alpha; CPT1; indole ethylamine derivatives | PROLIFERATOR-ACTIVATED RECEPTOR; PPAR-ALPHA; LIPOTOXICITY; OXIDATION | CPT1; indole ethylamine derivatives; NAFLD; PPARα | Antipsychotic Agents; Carnitine O-Palmitoyltransferase; Ethylamines; Humans; Indoles; Lipase; Lipid Metabolism; Non-alcoholic Fatty Liver Disease; Oleic Acid; PPAR alpha; acetyl coenzyme A carboxylase; carnitine palmitoyltransferase I; ethylamine; fenofibrate; oleic acid; peroxisome proliferator activated receptor alpha; triacylglycerol; triacylglycerol lipase; AML12 cell line; article; controlled study; drug analysis; drug development; drug therapy; fatty acid oxidation; fatty liver; human; in vitro study; lipid metabolism; lipid storage; lipogenesis; male; metabolic regulation; nonalcoholic fatty liver; nonhuman | English | 2024 | 2024-01 | 10.3390/molecules29010012 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of Illite Treatment on Quality Characteristics and Antioxidant Activity of Broccoli (Brassica oleracea L. var. italica) Sprouts | Microgreens have recently gained popularity owing to their reliable economic and nutritional value. This study aimed to increase the quality of microgreen broccoli via treatment with different concentrations (1%, IPB-1; 3%, IPB-3; 5%, IPB-5; or 7%, IPB-7 w/v) of illite-a natural mineral powder. The results showed that the illite treatments considerably increased the content of mineral elements, such as Ca, P, and K; of vitamin C; and of free amino acids; and also increased the total weight of the broccoli sprouts. The content of sulforaphane, a bioactive compound, also increased by up to 47% with illite treatment, with the highest increase being in the IPB-5 group. However, several of the parameters were lower in the IPB-7 group. Aromatic compounds were categorized by functional groups such as hydrocarbons which numbered 36, 30, 34, 28, and 30 in the control, IPB-1, IPB-3, IPB-5, and IPB-7 groups, respectively. We found 16, 15, 15, 13, and 14 sulfides, including dimethyl sulfide, in the control, IPB-1, IPB-3, IPB-5, and IPB-7 groups, respectively. Additionally, aldehydes, comprising seven compounds, were detected in the IPB-1, IPB-3, IPB-5, and IPB-7 groups. Illite treatment significantly increased the activities of antioxidants such as DPPH and the polyphenol content of the microgreens. These results indicate a potential role for appropriate illite doses in microgreen treatment to address multinutrient deficiencies and to increase the quality of microgreen vegetables. | Kim, So-Hyun; Dhungana, Sanjeev Kumar; Kim, Il-Doo; Adhikari, Arjun; Kim, Jeong-Ho | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41556, South Korea; Univ Calif Exeter, Div Agr & Nat Resources, Exeter, CA 93221 USA; Kyungpook Natl Univ, Int Inst Res & Dev, Daegu 41556, South Korea; Konkuk Univ, Dept Green Technol Convergence, Chungju 27478, South Korea | Adhikari, Arjun/AAV-6297-2021; Dhungana, Sanjeev/O-4097-2017; Kim, Jeong-Ho/A-7641-2018 | 58090464600; 56269940800; 56269995600; 57195601415; 57221537227 | hoya1209@kku.ac.kr; | MOLECULES | MOLECULES | 1420-3049 | 29 | 18 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2024 | 4.6 | 25.5 | 0.43 | 2025-05-07 | 1 | 1 | microgreen; nutrition; sulforaphane; compounds; mineral elements; antioxidant | ACCUMULATION; BIOSYNTHESIS; FERMENTATION; EXPRESSION | antioxidant; compounds; microgreen; mineral elements; nutrition; sulforaphane | Antioxidants; Ascorbic Acid; Brassica; Isothiocyanates; Minerals; Seedlings; Sulfides; Sulfoxides; antioxidant; ascorbic acid; isothiocyanic acid; mineral; sulfide; sulforaphane; sulfoxide; Brassica; chemistry; growth, development and aging; seedling | English | 2024 | 2024-09 | 10.3390/molecules29184347 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Hyperelastic and Stacked Ensemble-Driven Predictive Modeling of PEMFC Gaskets Under Thermal and Chemical Aging | This study comprehensively investigates the stress distribution and aging effects in Ethylene Propylene Diene Monomer (EPDM) and Liquid Silicone Rubber (LSR) gasket materials through a novel integration of hyperelastic modeling and advanced machine learning techniques. By employing the Mooney-Rivlin, Ogden, and Yeoh hyperelastic models, we evaluated the mechanical behavior of EPDM and LSR under conditions of no aging, heat aging, and combined heat- and sulfuric-acid exposure. Each model revealed distinct sensitivities to stress distribution and material deformation, with peak von Mises stress values indicating that LSR experiences higher internal stress than EPDM across all conditions. For instance, without aging, LSR shows a von Mises stress of 24.17 MPa compared to 14.96 MPa for EPDM, while under heat and sulfuric acid exposure, LSR still exhibits higher stress values, showcasing its resilience under extreme conditions. Additionally, the ensemble learning approach achieved a classification accuracy of 98% for LSR and 84% for EPDM in predicting aging effects, underscoring the robustness of our predictive framework. These findings offer practical implications for selecting suitable gasket materials and developing predictive maintenance strategies in industrial applications, such as fuel cells, where material integrity under stress and aging is paramount. | Park, Su-Yeon; Kareem, Akeem Bayo; Mustapha, Toyyeebah Ajibola; Joo, Woo-Jeong; Hur, Jang-Wook | Kumoh Natl Inst Technol, Dept Aeronaut Mech & Elect Convergence Engn, 61 Daehak Ro, Gumi Si 39177, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Math, 80 Daehak Ro, Daegu 41566, South Korea; Pyung Hwa Oil Seal Co Ltd, 597 Nongong Ro, Daegu 42982, South Korea | Kareem, Akeem/KLE-1303-2024; Kareem, Akeem Bayo/KLE-1303-2024 | 59426685100; 57295703700; 59426485400; 58666733000; 36639979300 | 20246039@kumoh.ac.kr;20216004@kumoh.ac.kr;mustaphatoyyeebah@knu.ac.kr;sorim2wn@ph.co.kr;hhjw88@kumoh.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 17 | 22 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 3.2 | 25.5 | 0 | 2025-05-07 | 0 | 0 | aging effects; deformation analysis; ensemble model; fuel cell reliability; gasket materials; hyperelastic models; PEMFC; predictive modeling; stress distribution | MECHANICAL-BEHAVIOR; SEALING PERFORMANCE; RUBBER; EPDM | aging effects; deformation analysis; ensemble model; fuel cell reliability; gasket materials; hyperelastic models; PEMFC; predictive modeling; stress distribution | Aging of materials; Silicones; Ageing effects; Deformation analysis; Ensemble models; Fuel cell reliability; Gasket materials; Hyperelastic models; Liquid silicone rubbers; P.E.M.F.C; Predictive models; Stresses distribution; Gaskets | English | 2024 | 2024-11 | 10.3390/ma17225675 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Improving the Energy Storage Performance in Bi0.5Na0.5TiO3-Based Ceramics by Combining Relaxor and Antiferroelectric Properties | Ceramic capacitors have received great attention for use in pulse power systems owing to their ultra-fast charge-discharge rate, good temperature stability, and excellent fatigue resistance. However, the low energy storage density and low breakdown strength (BDS) of ceramic capacitors limit the practical applications of energy storage technologies. In this work, we present a series of relaxor ferroelectric ceramics (1-x) [0.94 Bi0.5Na0.5TiO3 -0.06BaTiO3]- x Sr0.7Bi0.2TiO3 (1-x BNT-BT- x SBT; x = 0, 0.20, 0.225, 0.25, 0.275 and 0.30) with improved energy storage performances by combining relaxor and antiferroelectric properties. XRD, Raman spectra, and SEM characterizations of BNT-BT-SBT ceramics revealed a rhombohedral-tetragonal phase, highly dynamic polar nanoregions, and a reduction in grain size with a homogeneous and dense microstructure, respectively. A high dielectric constant of 1654 at 1 kHz and low remnant polarization of 1.39 mu C/cm2 were obtained with the addition of SBT for x = 0.275; these are beneficial for improving energy storage performance. The diffuse phase transition of these ceramics displays relaxor behavior, which is improved with SBT and confirmed by modified the Curie-Weiss law. The combining relaxor and antiferroelectric properties with fine grain size by the incorporation of SBT enables an enhanced maximum polarization of a minimized P-E loop, leading to an improved BDS. As a result, a high recoverable energy density Wrec of 1.02 J/cm3 and a high energy efficiency eta of 75.98% at 89 kV/cm were achieved for an optimum composition of 0.725 [0.94BNT-0.06BT]-0.275 SBT. These results demonstrate that BNT-based relaxor ferroelectric ceramics are good candidates for next-generation ceramic capacitors and offer a potential strategy for exploiting novel high-performance ceramic materials. | Pattipaka, Srinivas; Lim, Yeseul; Jeong, Yundong; Peddigari, Mahesh; Min, Yuho; Jeong, Jae Won; Jang, Jongmoon; Kim, Sung-Dae; Hwang, Geon-Tae | Pukyong Natl Univ, Dept Mat Sci & Engn, 45,Yongso Ro, Pusan 48513, South Korea; Indian Inst Technol Hyderabad, Dept Phys, Kandi 502284, Telangana, India; Kyungpook Natl Univ, Sch Mat Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Inst Mat Sci KIMS, Ceram Mat Div, 797 Changwondaero, Chang Won 51508, South Korea; Yeungnam Univ, Dept Elect Engn, Gyongsan 38541, South Korea | Min, Yuho/AAA-1287-2020; Pattipaka, Dr. Srinivas/AAD-8655-2022 | 57189258366; 58512860700; 59383572700; 56316365700; 36782804100; 56540094000; 55851287300; 56373258800; 36704574900 | cnuphy444@gmail.com;imyeseul21@pukyong.ac.kr;yd3998@pukyong.ac.kr;mahesh.p@phy.iith.ac.in;yuhomin@knu.ac.kr;jeongjw1204@kims.re.kr;jongmoon@yu.ac.kr;sdkim@pknu.ac.kr;gthwang@pknu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 17 | 20 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 3.2 | 25.5 | 0 | 2025-05-07 | 0 | 0 | ceramic capacitors; lead-free ceramics; relaxor and antiferroelectrics; energy storage density; energy efficiency | FIELD-INDUCED STRAIN; ELECTRIC-FIELD; DEPOLARIZATION TEMPERATURE; HARVESTING PROPERTIES; GIANT STRAIN; DENSITY; EFFICIENCY; CAPACITORS; STABILITY; FERROELECTRICS | ceramic capacitors; energy efficiency; energy storage density; lead-free ceramics; relaxor and antiferroelectrics | Absorption spectra; Antiferroelectric materials; Antiferroelectricity; Aspect ratio; Capacitor storage; Ceramic capacitors; Electric breakdown; Ferroelectricity; Light absorption; Permittivity; Sintering; Thermal fatigue; Anti ferroelectrics; Antiferroelectric properties; Energy; Energy storage density; Lead free ceramics; Relaxor and antiferroelectric; Relaxor properties; Relaxors; Storage performance; TiO; Ferroelectric ceramics | English | 2024 | 2024-10 | 10.3390/ma17205044 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Improving the Nonvolatile Memory Characteristics of Sol-Gel-Processed Y2O3 RRAM Devices Using Mono-Ethanolamine Additives | In this study, Y2O3-based resistive random-access memory (RRAM) devices with a mono-ethanolamine (MEA) stabilizer fabricated using the sol-gel process on indium tin oxide/glass substrates were investigated. The effects of MEA content on the structural, optical, chemical, and electrical characteristics were determined. As the MEA content increased, film thickness and crystallite size decreased. In particular, the increase in MEA content slightly decreased the oxygen vacancy concentration. The decreased film thickness decreased the physical distance for conductive filament formation, generating a strong electric field. However, owing to the lowest oxygen vacancy concentration, a large electrical field is required. To ensure data reliability, the endurance cycles across several devices were measured and presented statistically. Additionally, endurance performance improved with the increase in MEA content. Reduced oxygen vacancy concentration can successfully suppress the excess formation of the Ag conductive filament. This simplifies the transition from the high- to the low-resistance state and vice versa, thereby improving the endurance cycles of the RRAM devices. | Heo, Seongwon; Choi, Soohyun; Lee, Sangwoo; Cho, Yoonjin; Bae, Jin-Hyuk; Kang, In-Man; Kim, Kwangeun; Lee, Won-Yong; Jang, Jaewon | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Korea Aerosp Univ, Sch Elect & Informat Engn, Goyang 10540, South Korea; Kyungpook Natl Univ, Inst Elect Technol, Daegu 41566, South Korea | ; Lee, Hyun Woo/AAH-8473-2020 | 58960360300; 59401003400; 58567753300; 58567567900; 35326180700; 7203062678; 36004977500; 57209527128; 57194107504 | pos03034@knu.ac.kr;ctg999@naver.com;sangw98@knu.ac.kr;chongo815wls@knu.ac.kr;jhbae@ee.knu.ac.kr;imkang@ee.knu.ac.kr;kke@kau.ac.kr;yongsz@knu.ac.kr;j1jang@knu.ac.kr; | MATERIALS | MATERIALS | 1996-1944 | 17 | 21 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2024 | 3.2 | 25.5 | 0 | 2025-05-07 | 1 | 1 | sol-gel; RRAM; mono-ethanolamine; oxygen vacancy; Y2O3; endurance; retention | THIN-FILM TRANSISTORS; ROUTE; LAYER | endurance; mono-ethanolamine; oxygen vacancy; retention; RRAM; sol–gel; Y<sub>2</sub>O<sub>3</sub> | Crystallite size; Doping (additives); Ethanolamines; Indium compounds; Nonvolatile storage; Surface discharges; Conductive filaments; Endurance cycle; Film-thickness; Mono-ethanolamine; Oxygen vacancy concentration; Random access memory; Resistive random-access memory; Retention; Sol'gel; Y 2O 3; RRAM | English | 2024 | 2024-11 | 10.3390/ma17215252 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
