| ○ | ○ | Article | Masked Kinematic Continuity-aware Hierarchical Attention Network for pose estimation in videos | Existing methods for estimating human poses from video content exploit the temporal features of the video sequences and have shown impressive results. However, most methods address spatiotemporal issues separately. They compromise on accuracy to reduce jitter, or require high-resolution images to deal with occlusion, preventing full consideration of temporal features. Unfortunately, these two issues are interrelated. For example, occlusion causes uncertainty between successive frames, leading to unsmoothed results. To address these issues, we propose the Masked Kinematic Continuity-aware Hierarchical Attention Network (MHANet) as a novel framework that exploits masked kinematic keypoint features by extending our framework HANet framework. First, we randomly select and mask a keypoint to treat the masked keypoint as it is occluded, which allows us to make the network resilient to occlusion. We also use the velocity and acceleration of each individual keypoint to effectively capture temporal features. Second, the proposed hierarchical transformer encoder refines a 2D or 3D input pose derived from existing estimators by aggregating the masked continuity of the spatiotemporal dependencies of human motion. Finally, to facilitate collaborative optimization, we perform an online cross-supervision between the final pose from our decoder and the refined input pose produced by our encoder. We validate the effectiveness of our model demonstrating that our proposed approach improves PCK@0.05 by 14.1% and MPJPE by 8.7 mm compared to the existing method on a variety of tasks, including 2D and 3D pose estimation, body mesh recovery, and sparsely annotated multi-human pose estimation. | Jin, Kyung-Min; Lee, Gun-Hee; Nam, Woo-Jeoung; Kang, Tae-Kyung; Kim, Hyun-Woo; Lee, Seong-Whan | LG Elect Inc, 19 Yangjae Daero 11-Gil, Seoul 06772, South Korea; Korea Univ, Dept Artificial Intelligence, Anam Ro 145, Seoul 02841, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; LG AI Res, ISC 30,Magokjungang 10 Ro, Seoul 07796, South Korea | 57819311800; 57219703881; 57212464991; 57819313400; 56336378000; 7601390519 | sw.lee@korea.ac.kr; | NEURAL NETWORKS | NEURAL NETWORKS | 0893-6080 | 1879-2782 | 169 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;NEUROSCIENCES | 2024 | 6.3 | 10.4 | 1.15 | 2025-04-16 | 2 | 8 | Pose estimation; Body mesh recovery; Transformer; Video understanding | Body mesh recovery; Pose estimation; Transformer; Video understanding | Biomechanical Phenomena; Humans; Motion; Resilience, Psychological; Uncertainty; Mesh generation; Signal encoding; Video recording; Body mesh recovery; High-resolution images; Human pose; Keypoints; Pose-estimation; Temporal features; Transformer; Video contents; Video sequences; Video understanding; acceleration; Article; attention network; body mesh recovery; controlled study; human; image analysis; intermethod comparison; kinematics; Masked Kinematic Continuity-aware Hierarchical Attention Network; motion; online system; randomization; spatiotemporal analysis; temporal analysis; three-dimensional imaging; two-dimensional imaging; velocity; videorecording; biomechanics; psychological resilience; uncertainty; Kinematics | English | 2024 | 2024-01 | 10.1016/j.neunet.2023.10.038 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Multifaceted Effects of L-Cysteine, L-Ascorbic Acid, and Their Derivatives on the Viability and Melanin Synthesis of B16/F10 Cells under Different Conditions | The total melanin synthesis in the skin depends on various melanogenic factors, including the number of viable melanocytes, the level of melanogenic enzymes per cell, and the reaction rate of the enzymes. The purpose of this study is to examine the effects of L-cysteine (L-Cys), L-ascorbic acid (L-AA), and their derivatives on the tyrosinase (TYR) activity and autoxidation of L-3,4-dihydroxyphenylalanine (L-DOPA) in vitro and the viability and melanin synthesis of B16/F10 cells under different conditions. L-Cysteinamide (C-NH2), glutathione (GSH), L-Cys, L-AA, and N-acetyl L-cysteine (NAC) inhibited the catalytic activity of TYR in vitro. L-AA, C-NH2, L-ascorbic acid 2-O-glucoside (AAG), and 3-O-ethyl L-ascorbic acid (EAA) inhibited the autoxidation of L-DOPA in vitro. L-DOPA exhibited cytotoxicity at 0.1 mM and higher concentrations, whereas L-tyrosine (L-Tyr) did not affect cell viability up to 3 mM. L-AA, magnesium L-ascorbyl 2-phosphate (MAP), and L-Cys attenuated the cell death induced by L-DOPA. C-NH2 decreased the intracellular melanin level at the basal state, whereas L-AA, MAP, and AAG conversely increased it. C-NH2 reduced the number of darkly pigmented cells via in situ L-DOPA staining, whereas L-AA, MAP, GSH, and AAG increased it. C-NH2 decreased the intracellular melanin level at the alpha-melanocyte-stimulating hormone (alpha-MSH)-stimulated state, while NAC and GSH increased it. L-AA and C-NH2 decreased the intracellular melanin level at the L-Tyr-stimulated state, but NAC and GSH increased it. L-Ascorbyl tetraisopalmitate (ATI) showed no or minor effects in most experiments. This study suggests that L-AA can either promote or inhibit the different melanogenic factors, and C-NH2 can inhibit the multiple melanogenic factors consistently. This study highlights the multifaceted properties of L-Cys, L-AA, and their derivatives that can direct their therapeutic applications in hyperpigmentation, hypopigmentation, or both disorders. | Choi, Joon Yong; Ha, Jae Won; 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; Kyungpook Natl Univ, Dept Mol Med, Sch Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, 680 Gukchaebosang Ro, Daegu 41944, South Korea | 57576409100; 57210154932; 6602899130 | halo134679@knu.ac.kr;jaewon1226@knu.ac.kr;ycboo@knu.ac.kr; | ANTIOXIDANTS | ANTIOXIDANTS-BASEL | 2076-3921 | 13 | 3 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY | 2024 | 6.6 | 10.4 | 0.94 | 2025-05-07 | 2 | 2 | L-cysteine; L-ascorbic acid; L-cysteinamide; tyrosinase; L-tyrosine; L-3,4-dihydroxyphenylalanine; alpha-melanocyte-stimulating hormone; hyperpigmentation; hypopigmentation | IN-VITRO; HUMAN TYROSINASE; MELANOGENESIS; DOPA; PIGMENTATION; INACTIVATION; GLUTATHIONE; MELANOCYTES; AGENTS | alpha-melanocyte-stimulating hormone; hyperpigmentation; hypopigmentation; L-3,4-dihydroxyphenylalanine; L-ascorbic acid; L-cysteinamide; L-cysteine; L-tyrosine; tyrosinase | English | 2024 | 2024-03 | 10.3390/antiox13030330 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Optimization, Metabolomic Analysis, Antioxidant Potential and Depigmenting Activity of Polyphenolic Compounds from Unmature Ajwa Date Seeds (Phoenix dactylifera L.) Using Ultrasonic-Assisted Extraction | This study sought to optimize the ultrasonic-assisted extraction of polyphenolic compounds from unmature Ajwa date seeds (UMS), conduct untargeted metabolite identification and assess antioxidant and depigmenting activities. Response surface methodology (RSM) utilizing the Box-Behnken design (BBD) and artificial neural network (ANN) modeling was applied to optimize extraction conditions, including the ethanol concentration, extraction temperature and time. The determined optimal conditions comprised the ethanol concentration (62.00%), extraction time (29.00 min), and extraction temperature (50 degrees C). Under these conditions, UMS exhibited total phenolic content (TPC) and total flavonoid content (TFC) values of 77.52 +/- 1.55 mgGAE/g and 58.85 +/- 1.12 mgCE/g, respectively, with low relative standard deviation (RSD%) and relative standard error (RSE%). High-resolution mass spectrometry analysis unveiled the presence of 104 secondary metabolites in UMS, encompassing phenols, flavonoids, sesquiterpenoids, lignans and fatty acids. Furthermore, UMS demonstrated robust antioxidant activities in various cell-free antioxidant assays, implicating engagement in both hydrogen atom transfer and single electron transfer mechanisms. Additionally, UMS effectively mitigated tert-butyl hydroperoxide (t-BHP)-induced cellular reactive oxygen species (ROS) generation in a concentration-dependent manner. Crucially, UMS showcased the ability to activate mitogen-activated protein kinases (MAPKs) and suppress key proteins including tyrosinase (Tyr), tyrosinase-related protein-1 and -2 (Trp-1 and -2) and microphthalmia-associated transcription factor (MITF), which associated melanin production in MNT-1 cell. In summary, this study not only optimized the extraction process for polyphenolic compounds from UMS but also elucidated its diverse secondary metabolite profile. The observed antioxidant and depigmenting activities underscore the promising applications of UMS in skincare formulations and pharmaceutical developments. | Alshammari, Fanar; Alam, Md Badrul; Naznin, Marufa; Kim, Sunghwan; Lee, Sang-Han | Kyungpook Natl Univ, Grad Sch, Dept Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Food & Bioind Res Inst, Inner Beauty Antiaging Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Mass Spect Converging Res & Green Nano Mat Res Ctr, Daegu 41566, South Korea | Lee, Seung Eun/ABG-1607-2021; Kim, Sunghwan/HKN-9812-2023; Alam, Md Badrul/AFL-7668-2022 | 57191860948; 56706777100; 57195955389; 57203772967; 57221453703 | alfnar744@gmail.com;mbalam@knu.ac.kr;naznin@knu.ac.kr;sunghwank@knu.ac.kr;sang@knu.ac.kr; | ANTIOXIDANTS | ANTIOXIDANTS-BASEL | 2076-3921 | 13 | 2 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY | 2024 | 6.6 | 10.4 | 1.42 | 2025-05-07 | 4 | 5 | Ajwa date seeds; anti-tyrosinase; hyperpigmentation; response surface methodology; artificial neural network | RESPONSE-SURFACE METHODOLOGY; PHENOLIC-COMPOUNDS; BY-PRODUCTS; RSM; IDENTIFICATION; FRUIT; ANN | Ajwa date seeds; anti-tyrosinase; artificial neural network; hyperpigmentation; response surface methodology | English | 2024 | 2024-02 | 10.3390/antiox13020238 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Role of Oxidative Stress in Blood-Brain Barrier Disruption and Neurodegenerative Diseases | Upregulation of reactive oxygen species (ROS) levels is a principal feature observed in the brains of neurodegenerative diseases such as Parkinson's disease (PD) and Alzheimer's disease (AD). In these diseases, oxidative stress can disrupt the blood-brain barrier (BBB). This disruption allows neurotoxic plasma components, blood cells, and pathogens to enter the brain, leading to increased ROS production, mitochondrial dysfunction, and inflammation. Collectively, these factors result in protein modification, lipid peroxidation, DNA damage, and, ultimately, neural cell damage. In this review article, we present the mechanisms by which oxidative damage leads to BBB breakdown in brain diseases. Additionally, we summarize potential therapeutic approaches aimed at reducing oxidative damage that contributes to BBB disruption in neurodegenerative diseases. | Kim, Sehwan; Jung, Un Ju; Kim, Sang Ryong | Kyungpook Natl Univ, Sch Life Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, BK21 FOUR KNU Creat BioRes Grp, Daegu 41566, South Korea; Pukyong Natl Univ, Dept Food Sci & Nutr, Busan 48513, South Korea; Kyungpook Natl Univ, Brain Sci & Engn Inst, Daegu 41404, South Korea | 57193232250; 7007119425; 56486163800 | arputa@naver.com;jungunju@naver.com;srk75@knu.ac.kr; | ANTIOXIDANTS | ANTIOXIDANTS-BASEL | 2076-3921 | 13 | 12 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY | 2024 | 6.6 | 10.4 | 2.28 | 2025-05-07 | 12 | 15 | neurodegenerative diseases; reactive oxygen species; oxidative damage; blood-brain barrier; blood-derived protein | MITOCHONDRIAL PERMEABILITY TRANSITION; CYTOCHROME-C RELEASE; LIPID-PEROXIDATION; ALZHEIMER-DISEASE; DNA-DAMAGE; VITAMIN-E; PARKINSONS-DISEASE; ENDOTHELIAL-CELLS; N-ACETYLCYSTEINE; RED WINE | blood-derived protein; blood–brain barrier; neurodegenerative diseases; oxidative damage; reactive oxygen species | English | 2024 | 2024-12 | 10.3390/antiox13121462 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | RSM- and ANN-Based Multifrequency Ultrasonic Extraction of Polyphenol-Rich Sargassum horneri Extracts Exerting Antioxidative Activity via the Regulation of MAPK/Nrf2/HO-1 Machinery | Sargassum horneri (SH) is widely consumed as a healthy seaweed food in the Asia-Pacific region. However, the bioactive components contributing to its biological activity remain unknown. Herein, we optimized multifrequency ultrasonic-assisted extraction conditions to achieve higher antioxidant activity using a response surface methodology and an artificial neural network. High-resolution mass spectrometry (HRMS; negative mode) was used to tentatively identify the secondary metabolites in the optimized SH extract, which were further tested against oxidative stress in RAW264.7 cells. Additionally, the identified compounds were analyzed in silico to determine their binding energies with the Keap1 protein (4L7B). We identified 89 compounds using HRMS, among which 19 metabolites (8 polyphenolics, 2 flavonoids, 2 lignans, 2 terpenes, 2 tannins, 2 sulfolipids, and 1 phospholipid) were putatively reported for the first time in SH. The in vitro results revealed that optimized SH extract inhibited oxidative stress via the Nrf2/MAPKs/HO-1 pathway in a dose-dependent manner. This result was validated by performing in silico simulation, indicating that sargaquinoic acid and glycitein-7-O-glucuronide had the highest binding energies (-9.20 and -9.52 Kcal/mol, respectively) toward Keap1 (4L7B). This study offers a unique approach for the scientific community to identify potential bioactive compounds by optimizing the multivariant extraction processing conditions, which could be used to develop functional and nutraceutical foods. | Javed, Ahsan; Alam, Md Badrul; Naznin, Marufa; Ahmad, Raees; Lee, Chang Hyung; Kim, Sunghwan; Lee, Sang-Han | Kyungpook Natl Univ, Grad Sch, Dept Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Food & Bioind Res Inst, Inner Beauty Antiaging Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Mass Spect Converging Res Ctr, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Seoul Natl Univ, Bio MAX Inst, Seoul 08826, South Korea | Alam, Md Badrul/AFL-7668-2022; ALAM, MD BADRUL/AFL-7668-2022; Lee, Seung Eun/ABG-1607-2021; Lee, Chang Hyung/MTD-8229-2025; Javed, Ahsan/ABK-2648-2022; Kim, Sunghwan/HKN-9812-2023 | 57204433098; 56706777100; 57195955389; 57805062800; 56818086500; 57203772967; 57221453703 | ahsanjaved@knu.ac.kr;mbalam@knu.ac.kr;naznin@knu.ac.kr;ahmed@knu.ac.kr;changhyung@snu.ac.kr;sunghwank@knu.ac.kr;sang@knu.ac.kr; | ANTIOXIDANTS | ANTIOXIDANTS-BASEL | 2076-3921 | 13 | 6 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY | 2024 | 6.6 | 10.4 | 0.94 | 2025-05-07 | 2 | 2 | Sargassum horneri; multifrequency ultrasonic-assisted extraction; secondary metabolites; antioxidantive activity | IN-VITRO; ACCURACY; PATHWAY; STRESS | antioxidantive activity; multifrequency ultrasonic-assisted extraction; Sargassum horneri; secondary metabolites | English | 2024 | 2024-06 | 10.3390/antiox13060690 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Sequential Lateral Lymphatic Metastasis Shows Similar Oncologic Outcomes to Upward Spread in Advanced Rectal Cancer After Preoperative Chemoradiotherapy | BACKGROUND: Whether lateral pelvic node metastasis should be considered as a regional or systemic disease is a long-standing debate. Although previous Japanese studies have considered it to be locoregional disease, Western countries consider it a systemic disease and do not perform lateral pelvic node dissection after preoperative chemoradiotherapy. OBJECTIVE: To evaluate whether lateral pelvic node metastasis is a systemic or regional disease that is amenable to curative resection. DESIGN: Retrospective analysis of a prospectively collected database. SETTING: This study was conducted at a tertiary cancer center. PATIENTS: There were 616 consecutive patients who underwent curative total mesorectal excision alone or with lateral pelvic node dissection after preoperative chemoradiotherapy for locally advanced rectal cancer between 2011 and 2019. MAIN OUTCOME MEASURES: Three-year disease-free and overall survival. RESULTS: A total of 360 patients underwent total mesorectal excision, and 160 patients underwent total mesorectal excision with lateral pelvic node dissection. There was no difference in the 3-year disease-free survival (DFS; p = 0.844) or overall survival rates (p = 0.921) between the groups. Patients with lateral pelvic node metastasis showed DFS similar to those with perirectal lymph node metastasis in the total mesorectal excision group. In a subgroup analysis, patients with internal iliac pelvic node metastasis showed a disease-free survival comparable to those with perirectal node involvement, and patients with other lateral pelvic node metastasis showed a DFS similar to those with intermediate node involvement. In the lateral pelvic node dissection group, the lateral pelvic node metastatic rate was 32.5%. On multivariate analysis, fewer than 8 of the unilateral harvested lateral pelvic nodes and advanced ypT stage were significantly associated with poor disease-free survival. LIMITATION: The retrospective design. CONCLUSIONS: Lateral lymphatic metastasis showed oncologic outcomes similar to those of upward spread, especially perirectal lymph nodes metastasis. Large cohort studies with long-term follow-up are required to confirm these results.

| ○ | ○ | Article | Sustainable method for disposing of ceramic-coated battery separator via carbon dioxide-assisted thermochemical process | The increasing demand for energy storage systems is driven by variability in renewable energy sources and the substantial energy requirements of electric vehicles. However, the typical 3-10-year lifespan of lithium-ion batteries raises concern about their disposal. The environmental challenges associated with conventional disposal and recycling methods (landfilling, incineration, and pyrometallurgical/hydrometallurgical processes) include the release of microplastics and air pollutants, such as volatile organic compounds, from plastic components. To address these issues, we propose a thermochemical process for managing plastic waste from discarded batteries, focusing on a separator from lithium-ion batteries as a model feedstock. Using carbon dioxide (CO2) as a reaction medium enhances the sustainability of thermochemical processes. Specifically, co-feeding CO2 at elevated temperatures (>= 500 degrees C) improves syngas and C1-2-hydrocarbon production while reducing liquid pyrolysates. These reactions result from the partial oxidation of volatiles via gas-phase reactions with CO2. Incorporation of CO2 to optimize the conversion of battery separators into syngas represents an advancement toward the environmentally sound and efficient disposal of battery waste while yielding value-added products. | Lee, Sangyoon; Cho, Seong-Heon; Jung, Sungyup; Kwon, Kyungjung; Tsang, Yiu Fai; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Sejong Univ, Dept Energy & Mineral Resources Engn, Seoul 05006, South Korea; Educ Univ Hong Kong, Dept Sci & Environm Studies, Tai Po, Hong Kong 999077, Peoples R China; Educ Univ Hong Kong, State Key Lab Marine Pollut, Tai Po, Hong Kong 999077, Peoples R China | Kwon, Eilhann/AGY-3339-2022; Jung, Sungyup/GZG-6207-2022; Tsang, Yiu/AAJ-2524-2020; Kwon, Kyungjung/AAG-8735-2020; Lee, Sang/ABC-8385-2020 | 57214885455; 56583023200; 55073290800; 24479380200; 22954605700; 9240622100 | ek2148@hanyang.ac.kr; | JOURNAL OF ANALYTICAL AND APPLIED PYROLYSIS | J ANAL APPL PYROL | 0165-2370 | 1873-250X | 179 | SCIE | CHEMISTRY, ANALYTICAL;ENERGY & FUELS;ENGINEERING, CHEMICAL | 2024 | 6.2 | 10.4 | 0 | 2025-05-07 | 0 | 0 | Circular economy; Sustainable waste management; Lithium-ion battery waste; Thermo-chemical process; CO2 utilization | GAS SHIFT REACTION; ELECTROLYTE; CONVERSION; EMISSIONS; FTIR | Circular economy; CO2 utilization; Lithium-ion battery waste; Sustainable waste management; Thermo-chemical process | Ions; Lithium-ion batteries; Phase interfaces; Recycling; Renewable energy; Separators; Sustainable development; Synthesis gas; Volatile organic compounds; Waste disposal; Battery separators; Circular economy; CO2 utilization; Lithium-ion battery waste; Renewable energy source; Storage systems; Substantial energy; Sustainable waste management; Syn gas; Thermo chemical process; Carbon dioxide | English | 2024 | 2024-05 | 10.1016/j.jaap.2024.106466 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Syngas production through CO2-assisted catalytic pyrolysis of ethylene vinyl acetate (EVA) with a cobalt-based catalyst | Ethylene vinyl acetate (EVA) is a representative copolymer widely adopted across various sectors owing to its superior physiochemical properties; however, an environmentally benign protocol for the disposal of EVA waste has not yet been established owing to the various ratios of acetate to polyethylene. Therefore, in this study, we proposed an innovative thermochemical technique for converting EVA waste into energy resources, specifically syngas. CO2 2 was used to enhance the environmental sustainability of pyrolysis. Thermogravimetric analysis revealed that most of the EVA (approximately 99 wt%) was converted into pyrolytic oil and gases. However, the mechanistic features of CO2 2 in the pyrolysis of EVA could not be fully elucidated through single- or double-stage pyrolysis owing to the slow kinetics of the homogeneous reaction between CO2 2 and volatiles. To expedite the reaction kinetics, we used a cobalt (Co)-based catalyst (Co/SiO2). 2 ). In the presence of Co/SiO2, 2 , the concentration of CO produced under CO2 2 was approximately 30-fold higher than that under N2. 2 . Furthermore, the homogeneous reactions resulted in fewer benzene derivatives and polycyclic aromatic hydrocarbons (PAHs) in the pyrolytic oil under CO2 2 conditions. These experimental findings suggest that CO2 2 and EVA could serve as valuable feedstocks for the production of energy. | Cho, Seong-Heon; Park, Jonghyun; Jung, Sungyup; Lee, Doyeon; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Hanbat Natl Univ, Dept Civil & Environm Engn, Daejeon 305719, South Korea | Kwon, Eilhann/A-1225-2012; Jung, Sungyup/GZG-6207-2022 | 56583023200; 58544742000; 55073290800; 55881252900; 9240622100 | ek2148@hanyang.ac.kr; | JOURNAL OF ANALYTICAL AND APPLIED PYROLYSIS | J ANAL APPL PYROL | 0165-2370 | 1873-250X | 181 | SCIE | CHEMISTRY, ANALYTICAL;ENERGY & FUELS;ENGINEERING, CHEMICAL | 2024 | 6.2 | 10.4 | 0.25 | 2025-05-07 | 1 | 2 | Circular economy; Waste-to-energy; Waste valorization; Ethylene vinyl acetate; Carbon dioxide; Thermo-chemical process | PHOTOVOLTAIC MODULES; CO2; TEMPERATURE; MECHANISMS | Carbon dioxide; Circular economy; Ethylene vinyl acetate; Thermo-chemical process; Waste valorization; Waste-to-energy | Capillary flow; Catalysts; Cobalt; Energy resources; Ethylene; Pyrolysis; Reaction kinetics; Silicon; Sustainable development; Synthesis gas; Thermogravimetric analysis; Thermoplastic elastomers; Waste disposal; Catalytic pyrolysis; Circular economy; Cobalt-based catalysts; Ethylene vinyl acetates; Homogeneous reaction; Pyrolytic oil; Syngas production; Thermo chemical process; Waste to energy; Waste valorizations; Carbon dioxide | English | 2024 | 2024-08 | 10.1016/j.jaap.2024.106638 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | The Effect of the Root Bark of Lycium chinense (Lycii Radicis Cortex) on Experimental Periodontitis and Alveolar Bone Loss in Sprague-Dawley Rats | Lycii Radicis Cortex (LRC), the dried root bark of Lycium chinese Mill., has traditionally been used as a medicinal herb in East Asia to treat fever and hyperhidrosis. In the present study, we investigated the effects of LRC extract on ligation-induced experimental periodontitis and associated alveolar bone loss in rats. Twenty-four hours after ligation placement, LRC was orally administered once daily for 10 days. Firstly, LRC administration inhibited anaerobic bacterial proliferation and inflammatory cell infiltration in gingival tissues. Additionally, LRC exhibited anti-inflammatory effects by reducing the expression of inflammatory mediators, including prostaglandin E2, interleukin-1 beta, and tumor necrosis factor-alpha. LRC treatment also downregulated mRNA expression of these inflammatory mediators in lipopolysaccharide-stimulated RAW 264.7 cells by inhibiting the mitogen-activated protein kinases and nuclear factor-kappa B (NF-kappa B) signaling pathways. Furthermore, LRC showed an antioxidant effect by decreasing the malondialdehyde level and inducible nitric oxide synthase activity in gingival tissues. Moreover, LRC effectively prevented the connective tissue degradation by inhibiting matrix metalloproteinase-8 expression and the loss of collagen-occupied areas in gingival tissues. LRC also decreased the receptor activator of NF-kappa B ligand/osteoprotegerin (RANKL/OPG) ratio, as well as the number and occupied areas of osteoclasts on the alveolar bone surface, thereby inhibiting alveolar bone loss. In summary, these findings suggest that LRC is a promising medicinal herb for alleviating periodontitis and related alveolar bone loss through its antimicrobial, anti-inflammatory, and antioxidant properties. | Yang, Jinwon; Song, Hyosun; Lee, Jeongjun; Chung, Hunsuk; Kwon, Young-Sam; Jegal, Kyung-Hwan; Kim, Jae-Kwang; Ku, Sae-Kwang | Daegu Haany Univ, Coll Korean Med, Dept Anat & Histol, Gyongsan 38610, South Korea; Kyungpook Natl Univ, Coll Vet Med, Dept Vet Surg, Daegu 41566, South Korea; GAPI BIO Co Ltd, Hwaseong 18622, South Korea; Daegu Haany Univ, Coll Korean Med, Dept Korean Med Class, Gyongsan 38610, South Korea; Daegu Haany Univ, Coll Korean Med, Dept Physiol, Daegu 38610, South Korea | 59425486100; 59425950000; 57214357024; 59403883000; 7403459426; 56089517500; 57203554170; 7006331005 | yangjinwon@dhu.ac.kr;legendx0070@knu.ac.kr;orglab@gapibio.co.kr;hunsukchung@dongbangchem.co.kr;kwon@knu.ac.kr;jegalkh@dhu.ac.kr;kim-jk@dhu.ac.kr;gucci200@dhu.ac.kr; | ANTIOXIDANTS | ANTIOXIDANTS-BASEL | 2076-3921 | 13 | 11 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY | 2024 | 6.6 | 10.4 | 0 | 2025-05-07 | 1 | 1 | periodontitis; alveolar bone loss; anti-inflammatory; antioxidant; Lycii Radicis Cortex | LIGATURE-INDUCED PERIODONTITIS; NF-KAPPA-B; KUKOAMINE B; OXIDATIVE STRESS; IN-VITRO; RESORPTION; ACTIVATION; INHIBITOR; EXTRACT; DISEASE | alveolar bone loss; anti-inflammatory; antioxidant; Lycii Radicis Cortex; periodontitis | English | 2024 | 2024-11 | 10.3390/antiox13111332 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Therapeutic Potential and Mechanisms of Rosmarinic Acid and the Extracts of Lamiaceae Plants for the Treatment of Fibrosis of Various Organs | Fibrosis, which causes structural hardening and functional degeneration in various organs, is characterized by the excessive production and accumulation of connective tissue containing collagen, alpha-smooth muscle actin (alpha-SMA), etc. In traditional medicine, extracts of medicinal plants or herbal prescriptions have been used to treat various fibrotic diseases. The purpose of this narrative review is to discuss the antifibrotic effects of rosmarinic acid (RA) and plant extracts that contain RA, as observed in various experimental models. RA, as well as the extracts of Glechoma hederacea, Melissa officinalis, Elsholtzia ciliata, Lycopus lucidus, Ocimum basilicum, Prunella vulgaris, Salvia rosmarinus (Rosmarinus officinalis), Salvia miltiorrhiza, and Perilla frutescens, have been shown to attenuate fibrosis of the liver, kidneys, heart, lungs, and abdomen in experimental animal models. Their antifibrotic effects were associated with the attenuation of oxidative stress, inflammation, cell activation, epithelial-mesenchymal transition, and fibrogenic gene expression. RA treatment activated peroxisomal proliferator-activated receptor gamma (PPAR gamma), 5' AMP-activated protein kinase (AMPK), and nuclear factor erythroid 2-related factor 2 (NRF2) while suppressing the transforming growth factor beta (TGF-beta) and Wnt signaling pathways. Interestingly, most plants that are reported to contain RA and exhibit antifibrotic activity belong to the family Lamiaceae. This suggests that RA is an active ingredient for the antifibrotic effect of Lamiaceae plants and that these plants are a useful source of RA. In conclusion, accumulating scientific evidence supports the effectiveness of RA and Lamiaceae plant extracts in alleviating fibrosis and maintaining the structural architecture and normal functions of various organs under pathological conditions. | Boo, Yong Chool | Kyungpook Natl Univ, Sch Med, Dept Mol Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Biomed Sci, Plus KNU Biomed Convergence Program BK21, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, 680 Gukchaebosang Ro, Daegu 41944, South Korea | 6602899130 | ycboo@knu.ac.kr; | ANTIOXIDANTS | ANTIOXIDANTS-BASEL | 2076-3921 | 13 | 2 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY | 2024 | 6.6 | 10.4 | 1.45 | 2025-05-07 | 7 | 8 | rosmarinic acid; fibrosis; Lamiaceae; transforming growth factor beta 1; TGF-beta 1; Wnt; peroxisomal proliferator-activated receptor gamma; PPAR gamma; 5' AMP-activated protein kinase; AMPK; erythroid 2-related factor 2; NRF2 | WU-LING-SAN; ACTIVATED RECEPTOR-GAMMA; HEPATIC STELLATE CELLS; CUT LIVER SLICES; GROWTH-FACTOR; EARLY-ONSET; TGF-BETA; IN-VITRO; PATHWAY; PROLIFERATION | 5′ AMP-activated protein kinase; AMPK; erythroid 2-related factor 2; fibrosis; Lamiaceae; NRF2; peroxisomal proliferator-activated receptor γ; PPARγ; rosmarinic acid; TGF-β1; transforming growth factor β1; Wnt | English | 2024 | 2024-02 | 10.3390/antiox13020146 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Vutiglabridin Alleviates Cellular Senescence with Metabolic Regulation and Circadian Clock in Human Dermal Fibroblasts | The process of cellular senescence, which is characterized by stable cell cycle arrest, is strongly associated with dysfunctional cellular metabolism and circadian rhythmicity, both of which are reported to result from and also be causal to cellular senescence. As a result, modifying any of them-senescence, metabolism, or the circadian clock-may affect all three simultaneously. Obesity accelerates aging by disrupting the homeostasis of reactive oxygen species (ROS) via an increased mitochondrial burden of fatty acid oxidation. As a result, if senescence, metabolism, and circadian rhythm are all linked, anti-obesity treatments may improve metabolic regulation while also alleviating senescence and circadian rhythm. Vutiglabridin is a small molecule in clinical trials that improves obesity by enhancing mitochondrial function. We found that chronic treatment of senescent primary human dermal fibroblasts (HDFs) with vutiglabridin alleviates all investigated markers of cellular senescence (SA-beta-gal, CDKN1A, CDKN2A) and dysfunctional cellular circadian rhythm (BMAL1) while remarkably preventing the alterations of mitochondrial function and structure that occur during the process of cellular senescence. Our results demonstrate the significant senescence-alleviating effects of vutiglabridin, specifically with the restoration of cellular circadian rhythmicity and metabolic regulation. These data support the potential development of vutiglabridin against aging-associated diseases and corroborate the intricate link between cellular senescence, metabolism, and the circadian clock. | Heo, Jin-Woong; Lee, Hye-Eun; Lee, Jimin; Choi, Leo Sungwong; Shin, Jaejin; Mun, Ji-Young; Park, Hyung-Soon; Park, Sang-Chul; Nam, Chang-Hoon | Daegu Gyeongbuk Inst Sci & Technol, Sch Undergrad Studies, Coll Transdisciplinary Studies, Daegu 42988, South Korea; Daegu Gyeongbuk Inst Sci & Technol, Dept New Biol, Aging & Immun Lab, Daegu 42988, South Korea; Kyungpook Natl Univ, Sch Med, Daegu 41566, South Korea; Korea Brain Res Inst, Neural Circuit Res Grp, Daegu 41062, South Korea; Glaceum Inc, Res Dept, Suwon 16675, South Korea; Chonnam Natl Univ, Adv Inst Aging Sci, Future Life & Soc Res Ctr, Gwangju 61186, South Korea | Park, Hyung-Soon/B-3334-2010; Nam, Chang-Hoon/HTO-0998-2023; Park, SangChul/CAF-6192-2022 | 58177466800; 57226420017; 58177364700; 57883713800; 58137819300; 8654053900; 57883461100; 57191674610; 9846288200 | hjw001107@dgist.ac.kr;heni91@kbri.re.kr;jimin6440@dgist.ac.kr;leochoi@glaceum.com;jaejin@glaceum.com;jymun@kbri.re.kr;hspark@glaceum.com;scpark@snu.ac.kr;chang@dgist.ac.kr; | ANTIOXIDANTS | ANTIOXIDANTS-BASEL | 2076-3921 | 13 | 1 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY | 2024 | 6.6 | 10.4 | 1.05 | 2025-04-16 | 1 | 2 | human dermal fibroblasts; cellular senescence; circadian clocks; metabolism; mitochondrial homeostasis | OXIDATIVE STRESS; MITOCHONDRIAL DYSFUNCTION; HUMAN-CELLS; DNA-DAMAGE; KINASE; RHYTHM; CONNECTIONS; ACTIVATION; MECHANISMS; BMAL1 | cellular senescence; circadian clocks; human dermal fibroblasts; metabolism; mitochondrial homeostasis | English | 2024 | 2024-01 | 10.3390/antiox13010109 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Review | A review on the technologies for sustainable biohydrogen production | Biohydrogen is the very promising and environmentally feasible fuel alternative to meet out the present day growing energy demands. Nevertheless, profuse amount of biomasses derived from various sectors are successfully being employed as the sources of biohydrogen production. The availability and derivability of biomass could be categorized with respect to various generations based on their composition and hydrogen productivity. Eventhough, several technologies including photolysis, photo fermentation and dark fermentation are followed for potential biohydrogen production from lignocellulosic biomasses, a few practical difficulties are also being faced while application. Such limitations could be overcome by encountering integrative fermentation approaches along with metabolic engineering practices. However, the dark fermentative methods not only utilize organic wastes for the biohydrogen production but also significantly diminish the recalcitrant effects of the substrate for clean energy production. The present review implores on the analysis of metabolic reactions of aerobic and anaerobic microorganisms to unveil both microbiological and biotechnological aspects of hydrogen production. It also focuses on the possible technological approaches practised on various investigations to meet out the challenges confronted during biohydrogen production. | Ananthi, V.; Bora, Abhispa; Ramesh, U.; Yuvakkumar, R.; Raja, Karthik; Ponnuchamy, Kumar; Muthusamy, Govarthanan; Arun, A. | Madurai Kamaraj Univ, Dept Mol Biol, Madurai, Tamil Nadu, India; Alagappa Univ, Dept Microbiol, Karaikkudi, Tamil Nadu, India; Alagappa Univ, Dept Phys, Karaikkudi, Tamil Nadu, India; Saveetha Inst Med & Tech Sci, Saveetha Sch Engn, Ctr Appl Res, Chennai 602105, India; Alagappa Univ, Dept Anim Hlth & Management, Karaikkudi 630003, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Saveetha Inst Med & Tech Sci, Saveetha Dent Coll & Hosp, Dept Biomat, Chennai 600077, India | Veleeswaran, Ananthi/AAA-2152-2021; Muthusamy, Govarthanan/C-1491-2014; Bora, Abhispa/LWI-6840-2024; Ponnuchamy, Kumar/D-3470-2013; Arun, A./F-8986-2019 | 57078968600; 57210557182; 57214358186; 32267723400; 30767677600; 58108465500; 54881927600; 57078221100 | ananthyeswaran@gmail.com;arunalacha@gmail.com; | PROCESS SAFETY AND ENVIRONMENTAL PROTECTION | PROCESS SAF ENVIRON | 0957-5820 | 1744-3598 | 186 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 7.8 | 10.6 | 1.51 | 2025-05-07 | 13 | 13 | Biohydrogen; Biomasses; Generation; Fermentation; Microorganisms | FERMENTATIVE HYDROGEN-PRODUCTION; THERMOPHILES CALDICELLULOSIRUPTOR-SACCHAROLYTICUS; ENTEROBACTER-AEROGENES; RHODOBACTER-SPHAEROIDES; WASTE-WATER; EXTREME THERMOPHILES; LAMINARIA-JAPONICA; METHANE PRODUCTION; FOOD WASTE; CLOSTRIDIUM-PARAPUTRIFICUM | Biohydrogen; Biomasses; Fermentation; Generation; Microorganisms | Fermentation; Hydrogen production; Metabolic engineering; Metabolism; Microorganisms; Photolysis; Substrates; Bio-hydrogen; Bio-hydrogen production; Clean energy; Dark fermentation; Energy demands; Engineering practices; Generation; Lignocellulosic biomass; Organic wastes; Photo fermentation; Biomass | English | 2024 | 2024-06 | 10.1016/j.psep.2024.04.034 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Characterization of cement-slime mixture using time domain reflectometry | This study explores the electromagnetic characteristics of five cement-slime mixtures using two types of time domain reflectometry sensors. For 28 days of curing, compressive strength tests are conducted and electromagnetic signals are measured. The electromagnetic wave velocity and corresponding apparent permittivity are calculated, and the relationships between these properties and the compressive strengths of the mixtures are established. Results show that in the initial curing period, capturing the apparent permittivity using a conventional probe proves difficult due to the high electrical conductivity of the mixtures. In contrast, an insulated electrical wire can detect reflected signals across all slime ratios, but it exhibits less sensitivity to changes in the electromagnetic signal. The apparent permittivity decreases exponentially over the curing time, influenced by the hydration process. Strong correlations are found between the apparent permittivities derived from both sensors and between decreasing apparent permittivity and increasing compressive strength. | Lee, Dongsoo; Yoo, Younggeun; Lee, Jong-Sub; Byun, Yong-Hoon | Korea Univ, Sch Civil Environm & Architectural Engn, 145 Anam Ro, Seoul 02841, South Korea; Kyungpook Natl Univ, Dept Agr Civil Engn, 80 Daehak ro, Daegu 41566, South Korea | ; Lee, Jong-Sub/G-2752-2012; Byun, Yong-Hoon/JKI-8441-2023 | 57483228200; 59435411100; 55690048400; 42761048000 | yhbyun@knu.ac.kr; | MEASUREMENT | MEASUREMENT | 0263-2241 | 1873-412X | 236 | SCIE | ENGINEERING, MULTIDISCIPLINARY;INSTRUMENTS & INSTRUMENTATION | 2024 | 5.6 | 10.6 | 2.14 | 2025-05-07 | 3 | 5 | Apparent permittivity; Compressive strength; Electromagnetic wave; Slime; Time domain reflectometry | SOIL-WATER CONTENT; BULK ELECTRICAL-CONDUCTIVITY; END BEARING CAPACITY; PILE; TDR; STRENGTH; PROBES; CONCRETE; BEHAVIOR; PASTE | Apparent permittivity; Compressive strength; Electromagnetic wave; Slime; Time domain reflectometry | Cements; Circular waveguides; Compressive strength; Permittivity measurement; Reflection; Reflectometers; Wave propagation; Apparent permittivity; Curing periods; Electromagnetic characteristic; Electromagnetic signals; High electrical conductivity; Property; Slime; Strength tests; Time domain reflectometry; Wave velocity; Permittivity | English | 2024 | 2024-08-15 | 10.1016/j.measurement.2024.115071 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
