| ○ | ○ | Article | The impact of phenanthrene on membrane phospholipids and its biodegradation by Sphingopyxis soli | The direct interactions of bacterial membranes and polycyclic aromatic hydrocarbons (PAHs) strongly influence the biological processes, such as metabolic activity and uptake of substrates due to changes in membrane lipids. However, the elucidation of adaptation mechanisms as well as membrane phospholipid alterations in the presence of phenanthrene (PHE) from a-proteobacteria has not been fully explored. This study was conducted to define the degradation efficiency of PHE by Sphingopyxis soli strain KIT-001 in a newly isolated from Jeonju river sediments and to characterize lipid profiles in the presence of PHE in comparison to cells grown on glucose using quantitative lipidomic analysis. This strain was able to respectively utilize 1-hydroxy-2-naphthoic acid and salicylic acid as sole carbon source and approximately 90% of PHE (50 mg/L) was rapidly degraded via naphthalene route within 1 day incubation. In the cells grown on PHE, strain KIT-001 appeared to dynamically change profiles of meta-bolite and lipid in comparison to cells grown on glucose. The levels of primary metabolites, phosphatidylethanolamines (PE), and phosphatidic acids (PA) were significantly decreased, whereas the levels of phosphatidylcholines (PC) and phosphatidylglycerols (PG) were significantly increased. The adaptation mechanism of Sphingopyxis sp. regarded mainly the accumulation of bilayer forming lipids and anionic lipids to adapt more quickly under restricted nutrition and toxicity condition. Hence, these findings are conceivable that strain KIT-001 has a good adaptive ability and biodegradation for PHE through the alteration of phospholipids, and will be helpful for applications for effective bioremediation of PAHs-contaminated sites. | Shon, Jong Cheol; Noh, Young Ji; Kwon, Young Sang; Kim, Jong-Hwan; Wu, Zhexue; Seo, Jong-Su | Korea Inst Toxicol, Environm Chem Res Grp, Jinju 52834, South Korea; Kyungpook Natl Univ, Mass Spectrometry Convergence Res Inst, Daegu 41566, South Korea | Jong-Hwan, Kim/O-4992-2019 | 56010668800; 57214334002; 36087585500; 57203324952; 55523767300; 34968667600 | jsseo@kitox.re.kr; | ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY | ECOTOX ENVIRON SAFE | 0147-6513 | 1090-2414 | 192 | SCIE | ENVIRONMENTAL SCIENCES;TOXICOLOGY | 2020 | 6.291 | 8.1 | 1.08 | 2025-06-25 | 26 | 27 | Biodegradation; Phenanthrene; Metabolic pathway; Metabolomics; Lipidomics; Sphingopyxis soli strain KIT-001 | POLYCYCLIC AROMATIC-HYDROCARBONS; UNSATURATED FATTY-ACIDS; PSEUDOMONAS-PUTIDA; SALICYLATE 1,2-DIOXYGENASE; RELATIVE QUANTIFICATION; CARDIOLIPIN SYNTHESIS; DEGRADATION PATHWAYS; SOLVENT TOLERANCE; ESCHERICHIA-COLI; BACTERIAL | Biodegradation; Lipidomics; Metabolic pathway; Metabolomics; Phenanthrene; Sphingopyxis soli strain KIT-001 | Biodegradation, Environmental; Geologic Sediments; Lipidomics; Metabolomics; Naphthalenes; Naphthols; Phenanthrenes; Phospholipids; Salicylic Acid; Sphingomonadaceae; Alphaproteobacteria; Bacteria (microorganisms); Sphingopyxis; Sphingopyxis composta; 1 hydroxy 2 naphthoic acid; 2 naphthoic acid derivative; glucose; membrane phospholipid; phenanthrene; phosphatidic acid; phosphatidylcholine; phosphatidylethanolamine; phosphatidylglycerol; polycyclic aromatic hydrocarbon; unclassified drug; 1-hydroxy-2-naphthoic acid; naphthalene; naphthalene derivative; naphthol derivative; phenanthrene; phenanthrene derivative; phospholipid; salicylic acid; bacterium; biodegradation; bioremediation; lipid; metabolism; metabolite; PAH; phenanthrene; adaptation; Article; bacterial growth; bacterial metabolism; bacterial strain; bacterium isolate; biodegradation; bioremediation; carbon source; controlled study; Gram negative bacterium; incubation time; lipid analysis; lipid storage; lipidomics; metabolomics; microbial degradation; nonhuman; river sediment; sediment; soil pollution; Sphingopyxis soli; chemistry; isolation and purification; metabolism; microbiology; Sphingomonadaceae | English | 2020 | 2020-04-01 | 10.1016/j.ecoenv.2020.110254 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Development and Validation of the Mucosal Inflammation Noninvasive Index For Pediatric Crohn's Disease | BACKGROUND & AIMS: Mucosal healing (MH) has become a goal of therapy for Crohn's disease (CD), but frequent endoscopies are not feasible. We aimed to develop and validate a non-invasive index to assess mucosal inflammation in children with CD. METHODS: We collected data from the multi-center prospective ImageKids study, in which children with CD underwent ileocolonoscopy with magnetic resonance enterography. We investigated the association of pediatric CD activity index (PCDAI) items and laboratory test results with the simple endoscopic score for CD (SESCD). We used these data in a blended mathematical judgmental clinimetric approach to develop a weighted categorized index to identify children with CD who have MH, which we called the MINI index. We validated the index using data from 3 independent patient cohorts. The derivation and validation cohorts included 154 and 168 children, respectively (age 14.1 +/- 2.5 years and 14.2 +/- 3.9 years), of whom 16% and 36% had MH (defined as SESCD<3). RESULTS: In multivariable models, the stooling item of the PCDAI, erythrocyte sedimentation rate, and level of fecal calprotectin were associated with SESCD (all P < .05). We added data on level of C-reactive protein to develop the MINI index. MINI scores below 8 identified children with MH with 88% sensitivity and 85% specificity in the derivation cohort and with 84% sensitivity and 87% specificity in the validation cohorts. Ninety percent of the patients in the validation cohort with scores of 8 or more had active mucosal inflammation, yet 78% of patients with scores below 8 had MH. Scores below 6 increase the positive predictive value to 86%. CONCLUSIONS: We developed an index to non-invasively assess mucosal inflammation in children with CD. This index, identifies children with MH with high sensitivity and specificity. The added benefit of MINI over measurement of fecal calprotectin was small but significant, especially for patients with concentrations of fecal calprotectin from 100 to 599 mu g/g. | Cozijnsen, Martinus A.; Ben Shoham, Assaf; Kang, Ben; Choe, Byung-Ho; Choe, Yon Ho; Jongsma, Maria M.

| ○ | ○ | Article | Is dietary macronutrient intake associated with serum concentrations of organochlorine pesticides in humans? | In the general population, chronic exposure to low-dose persistent organic pollutants (POPs), particularly organochlorine pesticides (OCPs), has been recently linked to many chronic diseases. Widespread contamination of the food chain and human adipose tissue has made avoiding exposure to these chemicals impossible; thus, alternative strategies for decreasing the chemical burden must be investigated. Recently, macronutrient intake was found to significantly modify the toxicokinetics of POPs in animal experimental studies. Thus, we evaluated whether macronutrient intake was related to serum concentrations of OCPs in healthy adults without cardio-metabolic diseases. Subjects included 1,764 adults, aged 20 years or above, who participated in the National Health and Nutrition Examination Survey 1999-2004. Macronutrient intake was assessed based on a 24-h dietary recall interview. Six individual OCPs commonly detected among the general population were evaluated as markers of OCPs and other coexisting lipophilic chemicals stored in adipose tissue and released into circulation. High fat intake was associated with lower concentrations of OCPs, while high carbohydrate intake showed the opposite result. When three types of fats were individually evaluated, both saturated fatty acids and monounsaturated fatty acids, but not polyunsaturated fatty acids, were inversely associated with serum concentrations of OCPs. Adjustment for possible confounders did not change the results. When stratified by age, gender, body mass index, and physical activity, these associations were similar in most subgroups. Thus, similar to the findings observed in animal experimental studies, a moderate-fat diet with low carbohydrate intake was related to low serum concentrations of OCPs in humans. Although these findings need to be replicated, changing dietary macronutrient intake can be investigated as a practical strategy for dealing with unavoidable lipophilic chemical mixtures such as OCPs in modern society.

| ○ | ○ | Article | The overexpression of TDP-43 in astrocytes causes neurodegeneration via a PTP1B-mediated inflammatory response | Background Cytoplasmic inclusions of transactive response DNA binding protein of 43 kDa (TDP-43) in neurons and astrocytes are a feature of some neurodegenerative diseases, such as frontotemporal lobar degeneration with TDP-43 (FTLD-TDP) and amyotrophic lateral sclerosis (ALS). However, the role of TDP-43 in astrocyte pathology remains largely unknown. Methods To investigate whether TDP-43 overexpression in primary astrocytes could induce inflammation, we transfected primary astrocytes with plasmids encodingGfporTDP-43-Gfp. The inflammatory response and upregulation of PTP1B in transfected cells were examined using quantitative RT-PCR and immunoblot analysis. Neurotoxicity was analysed in a transwell coculture system of primary cortical neurons with astrocytes and cultured neurons treated with astrocyte-conditioned medium (ACM). We also examined the lifespan, performed climbing assays and analysed immunohistochemical data in pan-glial TDP-43-expressing flies in the presence or absence of aPtp61fRNAi transgene. Results PTP1B inhibition suppressed TDP-43-induced secretion of inflammatory cytokines (interleukin 1 beta (IL-1 beta), interleukin 6 (IL-6) and tumour necrosis factor alpha (TNF-alpha)) in primary astrocytes. Using a neuron-astrocyte coculture system and astrocyte-conditioned media treatment, we demonstrated that PTP1B inhibition attenuated neuronal death and mitochondrial dysfunction caused by overexpression of TDP-43 in astrocytes. In addition, neuromuscular junction (NMJ) defects, a shortened lifespan, inflammation and climbing defects caused by pan-glial overexpression of TDP-43 were significantly rescued by downregulation ofptp61f(theDrosophilahomologue of PTP1B) in flies. Conclusions These results indicate that PTP1B inhibition mitigates the neuronal toxicity caused by TDP-43-induced inflammation in mammalian astrocytes andDrosophilaglial cells. | Lee, Shinrye; Kim, Seyeon; Kang, Ha-Young; Lim, Hye Ryeong; Kwon, Younghwi; Jo, Myungjin; Jeon, Yu-Mi; Kim, Sang Ryong; Kim, Kiyoung; Ha, Chang Man; Lee, Seongsoo; Kim, Hyung-Jun | Korea Brain Res Inst KBRI, Dementia Res Grp, Daegu 41062, South Korea; DGIST, Dept Brain & Cognit Sci, Daegu 42988, South Korea; Korea Basic Sci Inst KBSI, Gwangju Ctr, Gwangju 61886, South Korea; Korea Brain Res Inst KBRI, Res Div, Daegu 41062, South Korea; Korea Brain Res Inst KBRI, Brain Res Core Facil, Daegu 41062, South Korea; Kyungpook Natl Univ, BK21 Plus KNU Creat BioRes Grp, Inst Life Sci & Biotechnol, Sch Life Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Brain Sci & Engn Inst, Daegu 41944, South Korea; Soonchunhyang Univ, Dept Med Biotechnol, Asan 31538, South Korea | ; Kim, Kiyoung/KDN-8906-2024 | 17342428400; 57194160625; 57203895327; 57212505315; 57194168806; 57189727853; 36158214700; 56486163800; 57202307555; 7202560711; 57192516634; 57191717907 | soolee@kbsi.re.kr;kijang1@kbri.re.kr; | JOURNAL OF NEUROINFLAMMATION | J NEUROINFLAMM | 1742-2094 | 17 | 1 | SCIE | IMMUNOLOGY;NEUROSCIENCES | 2020 | 8.322 | 8.2 | 2 | 2025-06-25 | 50 | 47 | Neurodegenerative disease; Neuroinflammation; Astrocytes; Tar DNA-binding protein 43; Protein tyrosine phosphatase 1B | AMYOTROPHIC-LATERAL-SCLEROSIS; NF-KAPPA-B; DROSOPHILA MODEL; MOTOR-NEURONS; MITOCHONDRIAL DYSFUNCTION; OXIDATIVE STRESS; BRAIN-DAMAGE; CELL-LINES; ALS; EXPRESSION | Astrocytes; Neurodegenerative disease; Neuroinflammation; Protein tyrosine phosphatase 1B; Tar DNA-binding protein 43 | Animals; Animals, Genetically Modified; Astrocytes; Cells, Cultured; DNA-Binding Proteins; Drosophila; Gene Expression; Inflammation Mediators; Male; Mice; Mice, Inbred C57BL; Nerve Degeneration; Protein Tyrosine Phosphatase, Non-Receptor Type 1; interleukin 1beta; interleukin 6; protein tyrosine phosphatase 1B; TAR DNA binding protein; tumor necrosis factor; autacoid; DNA binding protein; protein tyrosine phosphatase 1B; Ptpn1 protein, mouse; TDP-43 protein, mouse; animal cell; Article; astrocyte; brain nerve cell; coculture; controlled study; cytotoxicity test; dendritic spine; disorders of mitochondrial functions; down regulation; Drosophila; embryo; enzyme linked immunosorbent assay; genetic transfection; immunoblotting; immunocytochemistry; immunohistochemistry; inflammation; lifespan; mouse; nerve cell culture; nerve degeneration; neuromuscular junction; neurotoxicity; nonhuman; plasmid; protein expression; reverse transcription polymerase chain reaction; transgene; upregulation; animal; astrocyte; biosynthesis; C57BL mouse; cell culture; gene expression; genetics; male; metabolism; nerve degeneration; pathology; transgenic animal | English | 2020 | 2020-10-14 | 10.1186/s12974-020-01963-6 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Validation of the CAMD Score in Patients With Chronic Hepatitis B Virus Infection Receiving Antiviral Therapy | BACKGROUND & AIMS: Researchers previously developed a scoring system to determine the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B virus (HBV) infection, based on the presence of cirrhosis, patient age, male sex, and diabetes (called the CAMD scoring system). We validated the CAMD scoring system and compared its performance with that of other risk assessment models in an independent cohort. METHODS: We followed up 3277 patients with chronic HBV infection (mean age, 48.7 y; 62.6% male; 32.4% with cirrhosis) who were treated with entecavir (n = 1725) or tenofovir (n = 1552) as the first-line antiviral agent in 4 academic teaching hospitals in the Republic of Korea. The primary outcome was development of HCC. We evaluated the ability of the CAMD, PAGE-B, and mPAGE-B scoring systems to identify patients who would develop HCC using integrated area under the curve (iAUC) analysis. RESULTS: Over a median follow-up period of 58.2 months, 8.9% of the patients developed HCC. Patients who developed HCC were older, more likely to be male, and had higher proportions of cirrhosis and diabetes than patients who did not develop HCC (all P 13) (P < .001 for comparison of low- vs intermediate-score groups and between intermediate- vs high-score groups). The predicted and observed probabilities of HCC had excellent agreement. CONCLUSIONS: We validated the CAMD scoring system in determining the risk of HCC in patients with chronic HBV treatment receiving entecavir or tenofovir treatment. Validation was performed in a cohort of patients in the Republic of Korea, where most patients have genotype C2 HBV infection. | Kim, Seung Up; Seo, Yeon Seok; Lee, Han Ah; Kim, Mi Na; Kim, Eun Hwa; Kim, Ha Yan; Lee, Yu Rim; Lee, Hye Won; Park, Jun Yong; Kim, Do Young; Ahn, Sang Hoon; Han, Kwang-Hyub; Hwang, Seong Gyu; Rim, Kyu Sung; Um, Soon Ho; Tak, Won Young; Kweon, Young Oh; Kim, Beom Kyung; Park, Soo Young | Yonsei Univ, Coll Med, Dept Internal Med, 50-1 Yonsei Ro, Seoul 03722, South Korea; Yonsei Univ, Coll Med, Inst Gastroenterol, Seoul, South Korea; Yonsei Univ, Coll Med, Biostat Collaborat Unit, Dept Biomed Syst Informat, Seoul, South Korea; Severance Hosp, Yonsei Liver Ctr, Seoul, South Korea; Korea Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Cha Univ, CHA Bundang Med Ctr, Dept Internal Med, Seongnam, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, 130 Dongdeok Ro, Daegu 41944, South Korea | ; Kim, Sun/L-4239-2013; Kim, Yoon/G-6633-2015; Kim, Dong/F-4608-2014; Lee, Hye/D-9081-2016; Lee, YuRim/ITU-1407-2023; Park, Jun/H-7127-2019; SANG-HOON, AHN/AAV-2600-2020; Kim, Nayoung/J-5387-2012; Ahn, Sang Hoon/AFM-2603-2022 | 54933821200; 35234912400; 57190980926; 57202910894; 57201077476; 57027095900; 57194094753; 57200110315; 47861376300; 56119929100; 7401989551; 7402963689; 7404626618; 7007082564; 7005044023; 7004074582; 7004694832; 35302925200; 57191674344 | beomkkim@yuhs.ac;psyoung0419@gmail.com; | CLINICAL GASTROENTEROLOGY AND HEPATOLOGY | CLIN GASTROENTEROL H | 1542-3565 | 1542-7714 | 18 | 3 | SCIE | GASTROENTEROLOGY & HEPATOLOGY | 2020 | 11.382 | 8.2 | 1.66 | 2025-06-25 | 28 | 32 | Hepatitis B Virus; Hepatocellular Carcinoma; Prediction; Model; CAMD Score; Validation | PREDICT HEPATOCELLULAR-CARCINOMA; PRACTICE GUIDELINES MANAGEMENT; TRANSIENT ELASTOGRAPHY; LIVER FIBROSIS; RISK-FACTORS; MARKERS; SYSTEM | CAMD Score; Hepatitis B Virus; Hepatocellular Carcinoma; Model; Prediction; Validation | Antiviral Agents; Carcinoma, Hepatocellular; Female; Hepatitis B virus; Hepatitis B, Chronic; Humans; Liver Cirrhosis; Liver Neoplasms; Male; Middle Aged; Retrospective Studies; Tenofovir; entecavir; tenofovir disoproxil; antivirus agent; tenofovir; adult; antiviral therapy; area under the curve; Article; cancer risk; Child Pugh score; chronic hepatitis B; cirrhosis patient age male sex score; cohort analysis; controlled study; diabetes mellitus; disease association; female; follow up; human; integrated area under the curve; liver cell carcinoma; liver cirrhosis; major clinical study; male; modified PAGE B score; PAGE B score; probability; scoring system; South Korea; teaching hospital; validation study; complication; Hepatitis B virus; liver cell carcinoma; liver cirrhosis; liver tumor; middle aged; retrospective study | English | 2020 | 2020-03 | 10.1016/j.cgh.2019.06.028 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Overexpression of a proton pumping gene OVP1 enhances salt stress tolerance, root growth and biomass yield by regulating ion balance in rice (Oryza sativa L.) | Oryza sativa vacuolar H+-pyrophosphatase 1 (OVP1) regulates plant development and osmotic stress response through its function as an electrogenic proton (H+) pump in the vacuolar membrane. Here, we show that OVP1-overexpressing transgenic (OTG) rice plants display greater resistance to salt stress and root growth than wild-type (WT) rice plants. This improved performance of OTG plants under salt stress was attributed to increases in vacuolar pyrophosphatase (V-PPase) activity, ion uptake, and vacuolar cation ion antiporter gene expression. OTG plants had higher sodium levels in the vacuole than in the cytosol. Under natural paddy field conditions, OTG plants outperformed WT plants and produced more extensive root systems. OTG plants also had higher filler number, V-PPase activity, chlorophyll content, membrane stability, and ion uptake than WT plants. Transcript profiling analyses revealed that the expression levels of vacuolar H+-pump genes (ATPase and OVP1) and ion antiporter genes (CAX, MHX, and NHX) were higher in OTG plants than in WT plants. These combined results suggest that OVP1 overexpression affects salt stress responses, root development, and biomass yield by regulating ion balance in rice. | Kim, Jin-Ju; Park, Seong-Im; Kim, Yul-Ho; Park, Hyang-Mi; Kim, Young-Saeng; Yoon, Ho-Sung | Kyungpook Natl Univ, Coll Nat Sci, Dept Biol, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 Plus KNU Creat BioRes Grp, Daegu 41566, South Korea; Rural Dev Adm, Natl Inst Crop Sci, Highland Agr Res Inst, Pyeongchang 25342, South Korea; Rural Dev Adm, Natl Inst Crop Sci, Jeonju 54875, South Korea; Kyungpook Natl Univ, Res Inst Ulleung Do & Dok Do, Daegu 41566, South Korea; Kyungpook Natl Univ, Adv Bioresource Res Ctr, Daegu 41566, South Korea | 57203324864; 56310974600; 37084899500; 26425253900; 35798433500; 7402990205 | kyslhh1228@hanmail.net;hsy@knu.ac.kr; | ENVIRONMENTAL AND EXPERIMENTAL BOTANY | ENVIRON EXP BOT | 0098-8472 | 1873-7307 | 175 | SCIE | ENVIRONMENTAL SCIENCES;PLANT SCIENCES | 2020 | 5.545 | 8.3 | 1.13 | 2025-06-25 | 19 | 19 | Salt stress; Root growth; Antiporter; Ion uptake; Sodium sequestration; Biomass yield | VACUOLAR H PLUS; HETEROLOGOUS EXPRESSION; THELLUNGIELLA-HALOPHILA; NA+/H+ ANTIPORT; PPASE GENE; ARABIDOPSIS; PYROPHOSPHATASE; PLANT; DROUGHT; AVP1 | Antiporter; Biomass yield; Ion uptake; Root growth; Salt stress; Sodium sequestration | Oryza sativa; biomass; crop yield; gene expression; growth; ion; rice; root; salinity tolerance | English | 2020 | 2020-07 | 10.1016/j.envexpbot.2020.104033 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Photosynthetic traits and plant-water relations of two apple cultivars grown as bi-leader trees under long-term waterlogging conditions | Waterlogging has been one of the major problems in plant cultivation worldwide. As its frequency and severity are increasing in the era of climate change, waterlogging tolerance of fruit cultivars is an important factor that should be considered before plantation. In this study, we investigated leaf morphological traits, photosynthetic responses, and plant-water relations of the two most popular apple cultivars in Korea, Hongro (medium maturing) and Fuji (late maturing), under long-term waterlogging conditions. Experimental bi-leader trees grafted on a single M.9 rootstock were subjected to two irrigation regimes (well-irrigated and waterlogged) for 75 days. Waterlogging stress adversely affected most of the morphological, physiological, and anatomical characteristics as well as the plant-water relations in both cultivars; the negative effects of waterlogging were more pronounced in Hongro than in Fuji. Both cultivars experienced a significant decrease in leaf size, whereas leaf length was reduced significantly in Hongro and leaf width in Fuji. Predawn leaf water potential (Psi(PD)) decreased with waterlogging, but midday leaf water potential (Psi(MD)) was more significantly decreased in Hongro than in Fuji under waterlogging. Net photosynthetic rate (P-n) and stomatal conductance (g(s)) were significantly reduced in both cultivars; the reduction was greater in Hongro than in Fuji. A more pronounced reduction in vessel density, vessel diameter, and stomatal density (S-d) was observed in Hongro than in Fuji, resulting in greater reduction in daily sap flow and hydraulic conductivity in Hongro than in Fuji. These results indicate that Fuji was better adapted to waterlogging, as indicated by fewer changes in morphological, physiological, and anatomical responses when compared with those of Hongro. Our data suggest that the lower reduction in vessel density, vessel area, and vessel diameter in the Fuji cultivar under waterlogging are major factors that improve plant-water relations and photosynthetic performance, which in turn determine the leaf morphological characteristics and vegetative growth under prolonged waterlogging. | Bhusal, Narayan; Kim, Hyun Seok; Han, Su-Gon; Yoon, Tae-Myung | Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Seoul Natl Univ, Dept Forest Sci, Seoul 08826, South Korea; Seoul Natl Univ, Interdisciplinary Program Agr & Forest Meteorol, Seoul 08826, South Korea; Natl Ctr Agro Meteorol, Seoul 08826, South Korea; Seoul Natl Univ, Res Inst Agr & Life Sci, Seoul 08826, South Korea; Kyungpook Natl Univ, Apple Res Inst, Daegu 41566, South Korea | ; Bhusal, Narayan/AAE-9086-2019 | 57199327486; 57203630265; 57199650006; 50263701700 | bhusal.narayan4@snu.ac.kr;cameroncrazies@snu.ac.kr;han4793@hanmail.net;tmyoon@knu.ac.kr; | ENVIRONMENTAL AND EXPERIMENTAL BOTANY | ENVIRON EXP BOT | 0098-8472 | 1873-7307 | 176 | SCIE | ENVIRONMENTAL SCIENCES;PLANT SCIENCES | 2020 | 5.545 | 8.3 | 5.64 | 2025-06-25 | 73 | 73 | Leaf gas exchange; Leaf water potential; Malus x domestica; Microscopy; Stem sap flow; Xylem vessel | CHLOROPHYLL FLUORESCENCE; STOMATAL DENSITY; FLOODING STRESS; GENE-EXPRESSION; RESPONSES; TOLERANCE; PRUNUS; ROOTS; PARAMETERS; ADAPTATION | Leaf gas exchange; Leaf water potential; Malus × domestica; Microscopy; Stem sap flow; Xylem vessel | Korea; Malus x domestica; anatomy; cultivar; experimental study; irrigation; long-term change; photosynthesis; water stress; water use efficiency; waterlogging | English | 2020 | 2020-08 | 10.1016/j.envexpbot.2020.104111 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Uncoupled ductile fracture criterion considering secondary void band behaviors for failure prediction in sheet metal forming | A new phenomenological ductile fracture criterion that is proposed. The proposed model is associated with the micro mechanisms of void nucleation, void growth, and evolution of void coalescence. The secondary voids band and rotation of voids effect are considered in the new ductile fracture criterion. A series of upsetting test results of aluminum 2024-T351 and TRIP RA-K40/70 steel are used to construct and compare the accuracy of fracture locus proposed by new ductile fracture criterion, Modified Mohr-Coulomb criterion and extend Lou-Huh criterion. The fracture locus constructed using the proposed criterion is dose to the experimental data points over a wide stress state range from uniaxial compression to balanced biaxial tension. Then, a series of upsetting tests and square cup drawing tests are conducted with A16014-T4 to evaluate the accuracy of the proposed criterion. All results indicate that the proposed ductile fracture criterion can be utilized for predicting initial fracture in sheet metal forming. | Quach, Hung; Kim, Jin-Jae; Duc-Toan Nguyen; Kim, Young-Suk | Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea; Hanoi Univ Sci & Technol, Sch Mech Engn, Hanoi, Vietnam | Nguyen, Duc-Toan/B-1029-2016; Kim, Sang-Hoon/AAA-2248-2020 | 57211711094; 57209555877; 36805657000; 36065820800 | caekim@knu.ac.kr; | INTERNATIONAL JOURNAL OF MECHANICAL SCIENCES | INT J MECH SCI | 0020-7403 | 1879-2162 | 169 | SCIE | ENGINEERING, MECHANICAL;MECHANICS | 2020 | 5.329 | 8.5 | 2.91 | 2025-06-25 | 67 | 69 | A12024; TRIP RA-K40/70; A16014-T4; Stress triaxiality; Ductile fracture criteria | CUTOFF VALUE; MODEL; GROWTH; DAMAGE; DEFORMATION; SIMULATION; NUCLEATION; GURSON | Al2024; Al6014-T4; Ductile fracture criteria; Stress triaxiality; TRIP RA-K40/70 | Drawing (forming); High strength steel; Metal forming; Sheet metal; Transformation Induced Plasticity steel; Al2024; Al6014-T4; Ductile fracture criterion; Stress triaxiality; TRIP RA-K40/70; Ductile fracture | English | 2020 | 2020-03-01 | 10.1016/j.ijmecsci.2019.105297 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Adsorption of selected dyes on Ti3C2Tx MXene and Al-based metal-organic framework | MXene and metal organic framework (MOF) were used as the main adsorbents to remove synthetic dyes from model wastewater. Methylene blue (MB) and acid blue 80 (AB) were used as the model cationic and anionic synthetic dyes, respectively. To investigate the physicochemical properties of the adsorbents used, we carried out several characterizations using microscopy, powder X-ray diffraction, a porosimetry, and a zeta potential analyzer. The surface area of MXene and MOF was 9 and 630 m 2 g(-1), respectively, and their respective isoelectric points were approximately pH 3 and 9. Thus, MXene and MOF exhibited high capacity for MB (similar to 140 mg g(-1)) and AB (similar to 200 mg g(-1)) adsorption, respectively due to their electrostatic attractions when the concentrations of the adsorbents and adsorbates were 25 and 10 mg L-1. Furthermore, the MOF was able to capture the MB due mainly to hydrophobic interactions. In terms of the advantages of each adsorbent according to our experimental results, MXene exhibited fast kinetics and high selectivity. Meanwhile, the MOF had a high adsorption capacity for both MB and AB. The adsorption mechanisms of both adsorbents for the removal of MB and AB were clearly explained by the results of our analyses of solution pH, ionic strength, and the presence of divalent cation, anion, or humic acids, as well as other characterizations (i.e., Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy). According to our results, MOF and MXene can be used as economical treatments for wastewater containing organic pollutants regardless of charge (e.g., MB and AB), and positively charged one (e.g., MB), respectively. | Jun, Byung-Moon; Heo, Jiyong; Taheri-Qazvini, Nader; Park, Chang Min; Yoon, Yeomin | Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA; Korea Army Acad Youngcheon, Dept Civil & Environm Engn, 495 Hogook Ro, Youngcheon 38900, Gyeongbuk, South Korea; Univ South Carolina, Dept Chem Engn, Columbia, SC 29208 USA; Univ South Carolina, Biomed Engn Program, Columbia, SC 29208 USA; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | Park, Chang Min/CAA-8506-2022; Jun, Byung-Moon/Y-2134-2019; Yoon, Yeomin/KDP-2253-2024 | 55326699900; 42461338400; 36609373800; 57209588953; 7402126688 | yoony@cec.sc.edu; | CERAMICS INTERNATIONAL | CERAM INT | 0272-8842 | 1873-3956 | 46 | 3 | SCIE | MATERIALS SCIENCE, CERAMICS | 2020 | 4.527 | 8.6 | 6.83 | 2025-06-25 | 143 | 158 | Adsorption; Methylene blue; Acid blue 80; MXene; Metal-organic framework | ENDOCRINE-DISRUPTING COMPOUNDS; AQUEOUS-SOLUTIONS; ACTIVATED CARBON; METHYLENE-BLUE; WASTE-WATER; REMOVAL; ACID; PERFORMANCE; MECHANISM; ORANGE | Acid blue 80; Adsorption; Metal-organic framework; Methylene blue; MXene | Adsorption; Aromatic compounds; Crystalline materials; Dyes; Fourier transform infrared spectroscopy; Hydrophobicity; Ionic strength; Organic pollutants; Organic polymers; Organometallics; Physicochemical properties; Wastewater treatment; X ray photoelectron spectroscopy; Electrostatic attractions; High adsorption capacity; Hydrophobic interactions; Metal organic framework; Methylene Blue; MXene; Powder X ray diffraction; Zeta potential analyzers; Chemicals removal (water treatment) | English | 2020 | 2020-02-15 | 10.1016/j.ceramint.2019.09.293 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Capacitive property studies of electrochemically synthesized Co3O4 and Mn3O4 on inexpensive stainless steel current collector for supercapacitor application | Co3O4 and Mn(3)O(4 )have been considered as pseudocapacitive nanomaterials that are suitable for use in super-capacitors (SCs) because of the apparent role of the surface capacitive current and diffusive intercalation current in their electrical charge storage mechanism. This paper presents a study of the pseudocapacitive current distribution in Co3O4 and Mn3O4 thin films prepared by a simple low-temperature electrodeposition method for binder-free synthesis on inexpensive stainless steel current collectors for cost-effective SC application. After preparation, the thin films were investigated by using various characterization techniques. However, in a single-electrode SC test performed with Co3O4, both surface capacitive and diffusive intercalation currents contributed to the total current during a charging voltammogram scan, with the diffusive current dominating in the oxidation potential region. By contrast, in Mn3O4, a relatively small capacitive current contributed to the total current in a charging voltammogram scan. The pseudocapacitive Co3O4 and Mn3O4 thin films exhibited maximum specific capacitances of 131 and 109 F g(-1) in 2 M KOH and maximum specific discharge capacities of 14.8 and 33.0 mAh g(-1), respectively, which showed their potential for use in energy storage devices. | Maile, Nagesh; Shinde, S.

| ○ | ○ | Article | Decrease of Protein Vicinal Dithiols in Parkinsonism Disclosed by a Monoarsenical Fluorescent Probe | Vicinal dithiol-containing proteins (VDPs) play an important role in maintaining the structures and functions of proteins mainly through the conversion between dithiols and disulfide bonds. The content of VDPs also reflects the redox status of an organism. To specifically and expediently detect VDPs, we developed a turn-on monoarsenical fluorescent probe (NEP) based on the intramolecular charge transfer mechanism. Naphthalimide was chosen as a fluorophore and linked with the receptor moiety (cyclic dithiarsolane) via carbamate segment. In the presence of VDPs, NEP displays a strong green fluorescence signal produced by the cyclic dithiarsolane cleavage and subsequent intramolecular cyclization to liberate the fluorophore. Furthermore, NEP exhibits high selectivity toward VDPs over other protein thiols and low molecular weight thiols. The favorable properties of NEP enable it readily to detect VDPs in live cells and in vivo. In addition, a remarkable decrease of VDPs in parkinsonism was disclosed for the first time, highlighting that regulating VDPs level has a therapeutic potential for parkinsonism. | Hu, Guodong; Jia, Huiyi; Hou, Yanan; Han, Xiao; Gan, Lu; Si, Jing; Cho, Dong-Hyung; Zhang, Hong; Fang, Jianguo | Lanzhou Univ, Coll Chem & Chem Engn, State Key Lab Appl Organ Chem, Lanzhou 730000, Gansu, Peoples R China; Chinese Acad Sci, Inst Modern Phys, Dept Heavy Ion Radiat Med, Lanzhou 730000, Gansu, Peoples R China; Kyungpook Natl Univ, Sch Life Sci, Daegu 41566, South Korea | Choi, Hye Rin/JDV-9065-2023; Fang, Jianguo/K-8058-2016 | 57189215911; 57208392712; 57193744971; 57190807416; 57211730635; 13807670700; 35093684400; 57102182900; 23027231500 | zhangh@impcas.ac.cn;fangjg@lzu.edu.cn; | ANALYTICAL CHEMISTRY | ANAL CHEM | 0003-2700 | 1520-6882 | 92 | 6 | SCIE | CHEMISTRY, ANALYTICAL | 2020 | 6.986 | 8.6 | 1.13 | 2025-06-25 | 20 | 20 | STRESS-MEDIATED APOPTOSIS; THIOREDOXIN REDUCTASE; ARSENIC-BINDING; CELLS; DESIGN; QUANTIFICATION; IDENTIFICATION; FLUOROGENS; CONVERSION; THIOLS | Charge transfer; Covalent bonds; Cyclization; Fluorophores; Neurodegenerative diseases; Probes; Proteins; Sulfur compounds; Disulfide bonds; Fluorescent probes; Green fluorescence; High selectivity; Intra-molecular charge transfer; Intramolecular cyclizations; Low molecular weight; Therapeutic potentials; Fluorescence | English | 2020 | 2020-03-17 | 10.1021/acs.analchem.9b05232 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Dynamic phase-change metafilm absorber for strong designer modulation of visible light | Effective dynamic modulation of visible light properties has been significantly desired for advanced imaging and sensing technologies. In particular, phase-change materials have attracted much attention as active material platforms owing to their broadband tunability of optical dielectric functions induced by the temperature-dependent phase-changes. However, their uses for visible light modulators are still limited to meet multi-objective high performance owing to the low material quality factor and active tunability in the visible regime. Here, a design strategy of phase-change metafilm absorber is demonstrated by making the use of the material drawbacks and extending design degree of freedom. By engineering tunability of effective anisotropic permittivity tensor of VO2-Ag metafilm around near-unity absorption conditions, strong dynamic modulation of reflection wave is achieved with near-unity modulation depth at desired wavelength regions without sacrificing bandwidth and efficiency. By leveraging effective medium theory of metamaterial and coupled mode theory, the intuitive design rules and theoretical backgrounds are suggested. It is also noteworthy that the dynamic optical applications of intensity modulation, coloring, and polarization rotation are enabled in a single device. By virtue of ultrathin flat configuration of a metafilm absorber, design extensibility of reflection spectrum is also verified. It is envisioned that our simple and powerful strategy would play a robust role in development of miniaturized light modulating pixels and a variety of photonic and optoelectronic applications. © 2020 Sun-Je Kim et al., published by De Gruyter, Berlin/Boston 2020. | Kim, Sun-Je; Yun, Hansik; Choi, Sungwook; Yun, Jeong-Geun; Park, Kyungsoo; Jeong, Sun Jae; Lee, Seung-Yeol; Lee, Yohan; Sung, Jangwoon; Choi, Chulsoo; Hong, Jongwoo; Lee, Yong Wook; Lee, Byoungho | Inter-University Semiconductor Research Center, School of Electrical and Computer Engineering, Seoul National University, Gwanakro 1, Gwanak-Gu, Seoul, 08826, South Korea; Inter-University Semiconductor Research Center, School of Electrical and Computer Engineering, Seoul National University, Gwanakro 1, Gwanak-Gu, Seoul, 08826, South Korea; Interdisciplinary Program of Biomedical Mechanical and Electrical Engineering, School of Electrical Engineering, Pukyong National University, Yongso-ro 45, Nam-Gu, Busan, 48513, South Korea; Inter-University Semiconductor Research Center, School of Electrical and Computer Engineering, Seoul National University, Gwanakro 1, Gwanak-Gu, Seoul, 08826, South Korea; Interdisciplinary Program of Biomedical Mechanical and Electrical Engineering, School of Electrical Engineering, Pukyong National University, Yongso-ro 45, Nam-Gu, Busan, 48513, South Korea; Interdisciplinary Program of Biomedical Mechanical and Electrical Engineering, School of Electrical Engineering, Pukyong National University, Yongso-ro 45, Nam-Gu, Busan, 48513, South Korea; School of Electronics Engineering, College of IT Engineering, Kyungpook National University, Daehakro 80, Buk-gu, Daegu, 702-701, South Korea; Inter-University Semiconductor Research Center, School of Electrical and Computer Engineering, Seoul National University, Gwanakro 1, Gwanak-Gu, Seoul, 08826, South Korea; Inter-University Semiconductor Research Center, School of Electrical and Computer Engineering, Seoul National University, Gwanakro 1, Gwanak-Gu, Seoul, 08826, South Korea; Inter-University Semiconductor Research Center, School of Electrical and Computer Engineering, Seoul National University, Gwanakro 1, Gwanak-Gu, Seoul, 08826, South Korea; Inter-University Semiconductor Research Center, School of Electrical and Computer Engineering, Seoul National University, Gwanakro 1, Gwanak-Gu, Seoul, 08826, South Korea; Interdisciplinary Program of Biomedical Mechanical and Electrical Engineering, School of Electrical Engineering, Pukyong National University, Yongso-ro 45, Nam-Gu, Busan, 48513, South Korea; Inter-University Semiconductor Research Center, School of Electrical and Computer Engineering, Seoul National University, Gwanakro 1, Gwanak-Gu, Seoul, 08826, South Korea | 56541834200; 54685540400; 57203643072; 57193544561; 57193550998; 57192958862; 55881869300; 55620758200; 57193550982; 57194181311; 57013819400; 55265186100; 8114205400 | byoungho@snu.ac.kr; | Nanophotonics | NANOPHOTONICS-BERLIN | 2192-8606 | 2192-8614 | 10 | 1 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;OPTICS;PHYSICS, APPLIED | 2020 | 8.449 | 8.6 | 0.93 | 2025-06-25 | 15 | coupled mode theory; effective medium theory; metafilm; phase-change material; vanadium dioxide; visible light modulation | Degrees of freedom (mechanics); Dielectric materials; Imaging techniques; Light; Light modulation; Light modulators; Vanadium dioxide; Anisotropic permittivity; Dielectric functions; Effective medium theories; Intensity modulations; Material quality factor; Optoelectronic applications; Polarization rotation; Temperature dependent; Phase change materials | English | Final | 2020 | 10.1515/nanoph-2020-0264 | 바로가기 | 바로가기 | 바로가기 | |||||||
| ○ | ○ | Article | Enhanced photocatalytic activity and hydrogen evolution of CdS nanoparticles through Er doping | Generation of hydrogen fuel via the photocatalytic water splitting mechanism using semiconductor nanoparticles under sunlight irradiation is highly important. Moreover, the development of nanophotocatalysts for polluted water treatment is significant. In this regard, we synthesized CdS, CdS:Er (2 at%), and CdS:Er (4 at%) nanoparticles by a simple reflux route. According to the comprehensive structural analysis, Er3+ ions were incorporated into the CdS host lattice at the substitutional and interstitial sites, without altering the original structure. Photocatalytic measurements revealed that the degradation efficiency of 2 at% Er-doped CdS nanoparticles reached 100% within 100 min of visible light irradiation. In addition, CdS:Er (2 at%) nanoparticles exhibited enhanced photocatalytic hydrogen generation ability under simulated sunlight irradiation. Hence, from the obtained results, we concluded that CdS:Er (2 at%) nanoparticles are promising semiconductor photocatalytic materials for wastewater treatment as well as hydrogen fuel generation. | Poornaprakash, B.; Chalapathi, U.; Kumar, Mirgender; Subramanyam, K.; Vattikuti, S.
