| ○ | ○ | Article | Magnesium ferrite-reinforced polypyrrole hybrids as an effective adsorbent for the removal of toxic ions from aqueous solutions: Preparation, characterization, and adsorption experiments | Contaminated waters with high contents of toxic anions are detrimental to the human health and wildlife. Thus, the quality of drinking water should be carefully monitored. Adsorption technique has been determined to be a reasonable strategy out of several methods used to remove toxic anions from water. Novel MgFe2O4-reinforced polypyrrole (Ppy@x%MgFe2O4) (x = 1%, 2%, and 5% of MgFe2O4) hybrids were synthesized from a pyrrole monomer and MgFe2O4 using a simple chemical oxidation method. The fabricated hybrids were studied for their capability to remove PO4-, NO3-, and Cr(VI) from aqueous solutions. The results showed that PO43-, NO3-, and Cr (VI) removal was highly pH-dependent. The adsorption isotherms of hybrids were fitted well by the Langmuir model, with the maximum adsorption efficiency of 116.90, 76.14, and 138.60 mg/g for PO43-, NO3-, and Cr(VI), respectively. In addition, the above-mentioned toxic anions could be efficiently desorbed from spent Ppy@x% MgFe2O4 using a 0.1 M NaOH solution, and the hybrids exhibited good regenerability. The prepared materials are promising candidates for PO43-, NO3-, and Cr(VI) removal and exhibit high adsorption efficiency, rapid adsorption-desorption behavior, and appropriate recovery from the aqueous medium under external magnetic field. | Karthikeyan, Perumal; Elanchezhiyan, S.

| ○ | ○ | Article | Metagenomic analysis of microbial community and its role in bioelectrokinetic remediation of tannery contaminated soil | Tanneries create a serious threat to the environment by generating a significant amount of toxic metal-containing solid waste. This study deals with the application of bio-electrokinetic remediation (Bio-EK) of tannery effluent contaminated soil (TECS). Metagenomes representing the TECS sample were sequenced using the Illumina HiSeq platform. The bioreduction of hexavalent chromium Cr(VI)to trivalent chromium Cr (III) was achieved by BIO-EK techniques. NGS-data (Next Generation Sequencing) analysis was revealed that Proteobacteria, Firmicutes, Bacteroidetes, Actinobacteria, and Planctomycetes were identified in the bio-electrokinetic system. Proteobacteria are responsible for the bioreduction of chromium hexavalent by the formation of FeS particles. The biogenerated FeS particles can be reduced the toxic chromium (VI) to non?toxic chromium (III) in soil. Simultaneously total chromium and organic content were significantly removed in BIO-EK (40 and 290 mg kg-1) when compared to control soil (182 and 240 mg kg? 1). The presence of pollutant degrading microbes such as Desulfovibrio, Pseudomonas, Bacillus, Clostridium, Halanaerobium enhanced the bioreduction of the chromium during the electrokinetic remediation. This study can be claimed that the microbial cultures assisted electrokinetic remediation of total chromium, organic and iron in the tannery effluent contaminated soil was one of the suitable efficient techniques. In addition, the viability of the new combination technology developed (Electrokinetic + Bio) to treat low-permeability polluted soils was demonstrated. | Prakash, Arumugam Arul; Rajasekar, Aruliah; Sarankumar, Raja Kumaresan; AlSalhi, Mohamad S.; Devanesan, Sandhanasamy; Aljaafreh, Mamduh J.; Govarthanan, Muthusamy; Sayed, Shaban R.

| ○ | ○ | Article | Monodispersed core/shell nanospheres of ZnS/NiO with enhanced H2 generation and quantum efficiency at versatile photocatalytic conditions | This investigation is first to elucidate the synthesis of mono-dispersed ZnS/NiO-core/shell nanostructures with a uniform thin layer of NiO-shell on the ZnS-nanospheres as a core under controlled thermal treatments. NiO-shell thickness varied to 8.2, 12.4, 18.2, and 24.2 nm, while the ZnS-core diameter remained stable about 96 +/- 6 nm. The crystalline phase and core/shell structure of the materials were confirmed using XRD and HRTEM techniques, respectively. Optical properties through UV-vis spectroscopy analysis revealed the manifestation of redshift in the absorption spectrum of core/shell materials, while the XPS analysis of elements elucidated their stable oxidation states in ZnS/NiO core/shell structure. The optimized ZnS/NiO-core/shell showed 1.42 times higher H2 generation (162.1 mmol h(-1) g(1)(cat)(-)) than the pristine ZnS-core (113.2 mmol h(-1) g(cat)(-1) ), and 64.5 times higher than the pristine NiO-shell (2.5 mmol h(-1) g(cat)(-1)). The quantum efficiency at wavelengths of 420, 365 nm, and 1.5 G air mass filters was found to be 13.5%, 25.0%, and 45.3%, respectively. Water splitting experiments was also performed without addition of any additives, which showed enhanced H-2 gas evolution of 1.6 mmol h(-1) g(cat)(-1) under the sunlight illumination. Photoelectrochemical measurements revealed the stable photocurrent density and minimized charge recombination in the system. The performed recyclability and reusability tests for five recycles demonstrated the excellent stability of the developed photocatalysts. | Rao, Vempuluru Navakoteswara; Ravi, Parnapalle; Sathish, Marappan; Reddy, Nagappagari Lakshmana; Lee, Kiyoung; Sakar, Mohan; Prathap, Pathi; Kumari, Murikinati Mamatha; Reddy, Kakarla Raghava; Nadagouda, Mallikarjuna N.; Aminabhavi, Tejraj M.; Shankar, Muthukonda Venkatakrishnan | Yogi Vemana Univ, Dept Mat Sci & Nanotechnol, Nanocatalysis & Solar Fuels Res Lab, Kadapa 516005, Andhra Pradesh, India; Cent Electrochem Res Inst CSIR CECRI, Electrochem Power Sources Div, Karaikkudi 630003, Tamil Nadu, India; Acad Sci & Innovat Res AcSIR, Ghaziabad 201002, India; Kyungpook Natl Univ, Sch Nano & Mat Sci & Engn, Dept Energy Chem Engn, 2559 Gyeongsang Daero, Sangju 37224, South Korea; Kyungpook Natl Univ, Res Inst Environm Sci & Technol, 80 Daehak Ro, Daegu, South Korea; Jain Univ, Ctr Nano & Mat Sci, Bangalore 562112, Karnataka, India; CSIR, Photovolta Metrol Lab, Natl Phys Lab, Dr KS Krishnan Marg, New Delhi 110012, India; Univ Sydney, Sch Chem & Biomol Engn, Sydney, NSW 2006, Australia; Wright State Univ, Dept Mech & Mat Engn, Dayton, OH 45324 USA; SETs Coll Pharm, Dept Pharmaceut, Dharwad 580007, Karnataka, India | Aminabhavi, Tejraj/AAY-3470-2021; Kumari, Mamatha/ABE-9578-2021; Nadagouda, Mallikarjuna/J-5196-2019; Venkatakrishnan, Shankar/AAC-1460-2019; Marappan, Sathish/D-8362-2011; Rao, Vempuluru/ABG-8665-2021; Lee, Kiyoung/J-8680-2013; Kakarla, Raghava Reddy/AAZ-9856-2021; Muthukonds Venkatakrishnan, Shankar/AAC-1460-2019; Mohan, Sakar/O-3903-2017; Nagappagari, Lakshmana Reddy/K-2238-2019; N, Dr. Lakshmana Reddy/K-2238-2019 | 57196196615; 57196186668; 10340999600; 56499352000; 57219211501; 55911754000; 8620488800; 55861942200; 13611741600; 8720736200; 36048422400; 7005167181 | shankar@yogivemanauniversity.ac.in; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 413 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 2.83 | 2025-07-30 | 60 | 65 | Photocatalysis; Hydrogen production; Quantum efficiency; Core-shell nanostructures | HYDROGEN EVOLUTION; ZNS NANOPARTICLES; WATER; COMPOSITES; NANOCOMPOSITES; TIO2; NANOSTRUCTURES; SURFACE; DOTS | Core-shell nanostructures; Hydrogen production; Photocatalysis; Quantum efficiency | Absorption spectroscopy; Additives; Efficiency; II-VI semiconductors; Nanocrystalline materials; Nanospheres; Nickel oxide; Photocurrents; Red Shift; Reusability; Zinc sulfide; hydrogen; nanoshell; nanosphere; nickel oxide nanoparticle; water; zinc sulfide nanoparticle; Charge recombinations; Core/shell materials; Core/shell structure; Crystalline phase; Photocurrent density; Photoelectrochemical measurements; Shell thickness; VIS spectroscopy; absorption spectrum; air mass; catalysis; catalyst; concentration (composition); efficiency measurement; electrochemical method; oxidation; shell; absorption spectroscopy; Article; controlled study; crystal structure; dispersion; electrochemistry; heat treatment; high resolution transmission electron microscopy; illumination; oxidation; particle size; photocatalysis; photochemistry; quantum chemistry; recycling; red light; sunlight; synthesis; thickness; ultraviolet visible spectroscopy; X ray diffraction; X ray photoemission spectroscopy; Quantum efficiency | English | 2021 | 2021-07-05 | 10.1016/j.jhazmat.2021.125359 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Nonmonotonic response of type 2 diabetes by low concentration organochlorine pesticide mixture: Findings from multi-omics in zebrafish | Exposure to a single organochlorine pesticide (OCP) at high concentration and over a short period of exposure constrain our understanding of the contribution of chemical exposure to type 2 diabetes (T2D). A total of 450 male and female zebrafish was exposed to mixtures of five OCPs at 0, 0.05, 0.25, 2.5, and 25 mu g/L for 12 weeks. T2D-related hematological parameters (i.e., glucose, insulin, free fatty acid, and triglycerides) and mitochondrial complex I to IV activities were assessed. Metabolomics, proteomics, and transcriptomics were analyzed in female livers, and their data-driven integration was performed. High fasting glucose and low insulin levels were observed only at 0.05 mu g/L of the OCP mixture in females, indicating a nonlinear and sexually dependent response. We found that exposure to the OCP mixture inhibited the activities of mitochondrial complexes, especially III and IV. Combining individual and integrated omics analysis, T2D-linked metabolic pathways that regulate mitochondrial function, insulin signaling, and energy homeostasis were altered by the OCP mixture, which explains the observed phenotypic hematological effects. We demonstrated the cause-and-effect relationship between exposures to OCP mixture and T2D using zebrafish model. This study gives an insight into mechanistic research of metabolic diseases caused by chemical exposure using zebrafish. | Lee, Hyojin; Gao, Yan; Ko, Eun; Lee, Jihye; Lee, Hyun-Kyung; Lee, Sangkyu; Choi, Moonsung; Shin, Sooim; Park, Youngja Hwang; Moon, Hyo-Bang; Uppal, Karan; Kim, Ki-Tae | Seoul Natl Univ Sci & Technol, Dept Environm Energy Engn, Seoul 01811, South Korea; Kyungpook Natl Univ, Coll Pharm, BK21 FOUR Community Based Intelligent Novel Drug, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu 41566, South Korea; Chonnam Natl Univ, Dept Biotechnol & Bioengn, Gwangju 61186, South Korea; Korea Univ, Coll Pharm, Metabol Lab, Sejong City 30019, South Korea; Hanyang Univ, Dept Marine Sci & Convergent Technol, Ansan 15588, South Korea; Seoul Natl Univ Sci & Technol, Dept Optometry, Seoul 01811, South Korea; Seoul Natl Univ Sci & Technol, Convergence Inst Biomed Engn & Biomat, Seoul 01811, South Korea; Chonnam Natl Univ, Interdisciplinary Program Bioenergy & Biomat, Grad Sch, Gwangju 61186, South Korea; Emory Univ, Dept Med, Clin Biomarkers Lab, Atlanta, GA 30322 USA; Seoul Natl Univ Sci & Technol, Dept Environm Engn, Seoul 01811, South Korea | ; Moon, Hyo-Bang/M-7676-2017; KIM, KI-TAE/AAX-3175-2020 | 57200522840; 58736921100; 58147638300; 57221806058; 57205153916; 57209046767; 23396080300; 26435504000; 55947977200; 55957141700; 37666186700; 57202074566 | ktkim@seoultech.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 416 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 0.83 | 2025-07-30 | 21 | 21 | Organochlorine pesticide mixtures; Type 2 diabetes; Zebrafish; Multi-omics | PERSISTENT ORGANIC POLLUTANTS; C-REACTIVE PROTEIN; INSULIN; GLUCOSE; OBESITY; CELL; METABOLISM; EXPOSURE; MODEL; INTEGRATION | Multi-omics; Organochlorine pesticide mixtures; Type 2 diabetes; Zebrafish | Animals; Diabetes Mellitus, Type 2; Female; Hydrocarbons, Chlorinated; Insulin; Male; Pesticides; Zebrafish; Danio rerio; Fatty acids; Glucose; Insulin; Metabolism; Mitochondria; Molecular biology; Pesticides; adenosine triphosphate; cytochrome c oxidase; fatty acid; glucose; glutathione; insulin; malic acid; mitochondrial protein; organochlorine pesticide; pyruvic acid; reactive oxygen metabolite; reduced nicotinamide adenine dinucleotide dehydrogenase (ubiquinone); triacylglycerol; chlorinated hydrocarbon; insulin; pesticide; 'omics'; Chemical exposure; Mitochondrial complex; Multi-omic; Non-monotonic response; Organochlorine pesticide mixture; Organochlorine pesticides; Pesticide mixture; Type-2 diabetes; Zebrafish; cyprinid; diabetes; genetic analysis; glucose; homeostasis; organochlorine pesticide; phenotype; pollution exposure; proteomics; adult; animal experiment; animal model; animal tissue; Article; controlled study; detection algorithm; electron transport; enzyme activity; fasting; fatty acid blood level; female; glucose blood level; glucose metabolism; glutathione metabolism; hematological parameters; insulin blood level; insulin level; insulin signaling; male; metabolism; metabolomics; multiomics; non insulin dependent diabetes mellitus; nonhuman; protein expression; proteomics; real time polymerase chain reaction; transcriptomics; triacylglycerol blood level; zebra fish; animal; genetics; zebra fish; Mixtures | English | 2021 | 2021-08-15 | 10.1016/j.jhazmat.2021.125956 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Persistence, toxicological effect and ecological issues of endosulfan-A review | Endosulfan, an organochlorine pesticide, is categorized as persistent organic pollutants (POPs) in the Stockholm Convention and phased out globally. In this review, the distribution, toxicity, and interactive effect of endosulfan isomers and their remediation approaches are discussed. The occurrence of endosulfan residues in various environmental compartments (air, soil, and water) and biota (plants and animals) reported during 2016-2020 confirms its persistence and biomagnification probability in the ecosystem. The distribution pattern of endosulfan residues in the ecosystem is indicating both historical and recent input of endosulfan in the farmland. The existing literature on the ecotoxicological effects of endosulfan highlights various negative impacts on the nontargeted species, including plants, algae, aquatic species, terrestrial organisms, and mammals, including humans. Significantly, the toxicity of endosulfan could increase its intensity while interacting with other coexisting chemicals. Finally, this review suggests the distribution and persistence of endosulfan residues in the ecosystem could pose a potential risk to living organisms, including humans. | Sathishkumar, Palanivel; Mohan, Kannan; Ganesan, Abirami Ramu; Govarthanan, Muthusamy; Yusoff, Abdull Rahim Mohd; Gu, Feng Long | South China Normal Univ, Minist Educ, Key Lab Theoret Chem Environm, Sch Chemv, Guangzhou 510006, Peoples R China; Sri Vasavi Coll, PG & Res Dept Zool, Erode 638316, Tamil Nadu, India; Laimburg Res Ctr, Grp Fermentat & Distillat, Laimburg 6, I-39040 Post Auer, BZ, Italy; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Univ Teknol Malaysia, Fac Sci, Dept Chem, Johor Baharu 81310, Johor, Malaysia | Muthusamy, Govarthanan/C-1491-2014; Yusoff, Abdull/A-7357-2011; Govarthanan, Muthusamy/C-1491-2014; Gu, Feng Long/IZD-9142-2023; Sathishkumar, Palanivel/J-1088-2016 | 26635787300; 55928892800; 57200687865; 54881927600; 46861691500; 35229174000 | gu@scnu.edu.cn; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 416 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 1.24 | 2025-07-30 | 80 | 88 | Endosulfan; Interactive effects; Organochlorine pesticide; Persistent organic pollutant; Toxicity | ISIMANGALISO WETLAND PARK; ULTRAVIOLET-B RADIATION; CURRENT-USE PESTICIDES; ORGANOCHLORINE INSECTICIDE ENDOSULFAN; AMPHIBIAN POPULATION DECLINES; EMBRYO-LARVAL DEVELOPMENT; HEALTH-RISK ASSESSMENT; HUMAN LIVER-MICROSOMES; SOUTH-AMERICAN TOAD; ORGANIC POLLUTANTS | Endosulfan; Interactive effects; Organochlorine pesticide; Persistent organic pollutant; Toxicity | Stockholm; Mammalia; Aquatic organisms; Ecosystems; Insecticides; Isomers; Mammals; Toxicity; endosulfan; ground water; rain; sea water; surface water; Air soils; Air-water; Distribution effect; Endosulfans; Environmental compartment; Interactive effect; Organics; Organochlorine pesticides; Stockholm; Toxicological effects; ecotoxicology; endosulfan; environmental issue; persistent organic pollutant; agricultural land; air; alga; Amphibia; aquatic species; bioaccumulation; biota; bird; Crustacea; ecosystem; ecotoxicology; fish; human; insect; mammal; metabolism; nematode; nonhuman; persistent organic pollutant; plant; reptile; Review; sediment; soil; soil microflora; soil organism; terrestrial species; Organic pollutants | English | 2021 | 2021-08-15 | 10.1016/j.jhazmat.2021.125779 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Risk assessment of asbestos containing materials in a deteriorated dwelling area using four different methods | The release of asbestos fibers in old buildings, during demolition, or remodeling is associated with severe public health risks to building occupants and workers. In Korea, asbestos was used in several building materials during the 20th century. Although the use of asbestos is currently banned, its widespread earlier use and the current government initiatives to revitalize dilapidated areas make it essential to accurately evaluate the location and status of asbestos-containing materials (ACMs). This study surveyed buildings in an area of deteriorated dwellings targeted for renewal and determined the status and distribution of ACMs in that area. Asbestos distribution maps were generated and asbestos characteristics were analyzed. In addition, the risk posed by the identified ACMs was assessed using four international methods (the Korean Ministry of Environment, US Environmental Protection Agency, American Society for Testing and Materials, and UK Health and Safety Executive methods), and the results were compared. Notable differences between the assessment results were identified and were found to reflect the specific characteristics of buildings in the study area. These findings suggest ACM risk assessments should be specifically tailored to the regions in which they are applied, thereby improving ACM management and promoting both worker and occupant health. | Zhang, Yuan-Long; Byeon, Hwi-Seok; Hong, Won-Hwa; Cha, Gi-Wook; Lee, Yoon-Ha; Kim, Young-Chan | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, 80 Daehak Ro, Daegu 41566, South Korea; Dankook Univ, Dept Architectural Engn, 152 Jukjeon Ro, Yongin 16890, South Korea; Hanyang Univ, Innovat Durable Bldg & Infrastruct Res Ctr, 55 Hanyangdaehak Ro, Ansan 426791, South Korea; Changshin Univ, Dept Fire & Disaster Prevent Engn, 262 Paryong Ro, Changwon Si 51352, Gyeongsangnam D, South Korea | zhang, yuanlong/JEZ-4373-2023 | 56464271500; 57220177069; 7401527968; 55754413300; 57218699556; 56463201400 | yyoungchani@gmail.com; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 410 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 0.59 | 2025-07-30 | 13 | 14 | Asbestos risk; Asbestos containing material; Building material; Worker health | MESOTHELIOMA; EXPOSURE; BUILDINGS; MORTALITY; CANCER; WORKER | Asbestos containing material; Asbestos risk; Building material; Worker health | Asbestos; Construction Materials; Humans; Public Health; Republic of Korea; Risk Assessment; United States; Environmental Protection Agency; Health; Health risks; Housing; Human resource management; Occupational risks; Public risks; Risk assessment; Safety testing; asbestos; American society for testing and materials; Asbestos containing materials; Distribution maps; Government initiatives; Health and safety executives; Ministry of environments; Occupant healths; US Environmental Protection Agency; building material; human; public health; risk assessment; South Korea; United States; Asbestos | English | 2021 | 2021-05-15 | 10.1016/j.jhazmat.2020.124645 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Silencing the alarm: an insect salivary enzyme closes plant stomata and inhibits volatile release | Herbivore-induced plant volatiles (HIPVs) are widely recognized as an ecologically important defensive response of plants against herbivory. Although the induction of this 'cry for help' has been well documented, only a few studies have investigated the inhibition of HIPVs by herbivores and little is known about whether herbivores have evolved mechanisms to inhibit the release of HIPVs. To examine the role of herbivore effectors in modulating HIPVs and stomatal dynamics, we conducted series of experiments combining pharmacological, surgical, genetic (CRISPR-Cas9) and chemical (GC-MS analysis) approaches. We show that the salivary enzyme, glucose oxidase (GOX), secreted by the caterpillar Helicoverpa zea on leaves, causes stomatal closure in tomato (Solanum lycopersicum) within 5 min, and in both tomato and soybean (Glycine max) for at least 48 h. GOX also inhibits the emission of several HIPVs during feeding by H. zea, including (Z)-3-hexenol, (Z)-jasmone and (Z)-3-hexenyl acetate, which are important airborne signals in plant defenses. Our findings highlight a potential adaptive strategy where an insect herbivore inhibits plant airborne defenses during feeding by exploiting the association between stomatal dynamics and HIPV emission. | Lin, Po-An; Chen, Yintong; Chaverra-Rodriguez, Duverney; Heu, Chan Chin; Bin Zainuddin, Nursyafiqi; Sidhu, Jagdeep Singh; Peiffer, Michelle; Tan, Ching-Wen; Helms, Anjel; Kim, Donghun; Ali, Jared; Rasgon, Jason L.; Lynch, Jonathan; Anderson, Charles T.; Felton, Gary W. | Penn State Univ, Dept Entomol, 501 ASI Bldg, University Pk, PA 16802 USA; Penn State Univ, Dept Biol, 415 Life Sci Bldg, University Pk, PA 16802 USA; Univ Calif San Diego, Dept Cell & Dev Biol, 9500 Gilman Dr 0335, La Jolla, CA 92093 USA; Univ Putra Malaysia, Fac Agr, Dept Plant Protect, Serdang 43400, Selangor, Malaysia; Penn State Univ, Dept Plant Sci, 310 Tyson Bldg, University Pk, PA 16802 USA; Texas A&M Univ, Entomol Res Lab 103DA, Dept Entomol, College Stn, TX 77843 USA; Kyungpook Natl Univ, Dept Appl Biol, 80 Daehakro, Daegu 41566, South Korea | Zainuddin, Nursyafiqi Bin/GSO-2156-2022; Felton, Gary/E-8575-2013; Anderson, Charles/IWU-6229-2023; Chaverra Rodriguez, Duverney/GLV-2686-2022; Tan, Ching-Wen/AAR-6787-2020; Helms, Anjel/X-8794-2018; Lin, Po-An/JRY-1634-2023 | 57210255922; 57204115882; 59454606800; 54784211500; 57222106327; 57203154955; 6602287804; 7402817809; 55545906100; 56115927500; 35745556800; 6602544410; 7403674355; 56896199900; 7102783537 | pbl5066@psu.edu;gwf10@psu.edu; | NEW PHYTOLOGIST | NEW PHYTOL | 0028-646X | 1469-8137 | 230 | 2 | SCIE | PLANT SCIENCES | 2021 | 10.323 | 3.1 | 3.14 | 2025-07-30 | 58 | 51 | effector; HIPV; insect herbivore; plant defense; stomata | GREEN LEAF VOLATILES; HYDROGEN-PEROXIDE; OXIDATIVE STRESS; GLUCOSE-OXIDASE; HERBIVORE; CUES; DEFENSES; LEAVES | effector; HIPV; insect herbivore; plant defense; stomata | Animals; Herbivory; Insecta; Moths; Plant Stomata; Volatile Organic Compounds; Glycine max; Helicoverpa zea; Hexapoda; Lycopersicon esculentum; volatile organic compound; caterpillar; enzyme activity; gene expression; genetic engineering; inhibition; saliva; stomatal conductance; vegetable; volatile organic compound; animal; herbivory; insect; moth; plant stoma | English | 2021 | 2021-04 | 10.1111/nph.17214 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | STK3/STK4 signalling in adipocytes regulates mitophagy and energy expenditure | Cho et al. show regulation of mitophagy, and thereby energy expenditure, in adipocytes by the Hippo pathway kinases STK3 and STK4, independently of classical Hippo signalling. Genetic inactivation of Stk3 and Stk4 is shown to protect mice from the adverse metabolic effects of diet-induced obesity. Obesity reduces adipocyte mitochondrial function, and expanding adipocyte oxidative capacity is an emerging strategy to improve systemic metabolism. Here, we report that serine/threonine-protein kinase 3 (STK3) and STK4 are key physiological suppressors of mitochondrial capacity in brown, beige and white adipose tissues. Levels of STK3 and STK4, kinases in the Hippo signalling pathway, are greater in white than brown adipose tissues, and levels in brown adipose tissue are suppressed by cold exposure and greatly elevated by surgical denervation. Genetic inactivation of Stk3 and Stk4 increases mitochondrial mass and function, stabilizes uncoupling protein 1 in beige adipose tissue and confers resistance to metabolic dysfunction induced by high-fat diet feeding. Mechanistically, STK3 and STK4 increase adipocyte mitophagy in part by regulating the phosphorylation and dimerization status of the mitophagy receptor BNIP3. STK3 and STK4 expression levels are elevated in human obesity, and pharmacological inhibition improves metabolic profiles in a mouse model of obesity, suggesting STK3 and STK4 as potential targets for treating obesity-related diseases. | Cho, Yoon Keun; Son, Yeonho; Saha, Abhirup; Kim, Doeun; Choi, Cheoljun; Kim, Minsu; Park, Ji-Hyun; Im, Hyeonyeong; Han, Juhyeong; Kim, Kyungmin; Jung, Young-Suk; Yun, Jeanho; Bae, Eun Ju; Seong, Je Kyung; Lee, Mi-Ock; Lee, Sangkyu; Granneman, James G.; Lee, Yun-Hee | Seoul Natl Univ, Res Inst Pharmaceut Sci, Coll Pharm, Seoul, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Coll Pharm, BK21 Plus KNU Multiom Based Creat Drug Res Team, Daegu, South Korea; Pusan Natl Univ, Coll Pharm, Busan, South Korea; Dong A Univ, Grad Sch, Dept Translat Biomed Sci, Busan, South Korea; Chonbuk Natl Univ, Coll Pharm, Jeonju, South Korea; Seoul Natl Univ, Coll Vet Med, Res Inst Vet Sci, BK21 Plus Program Adv Vet Sci,Lab Dev Biol & Geno, Seoul, South Korea; Seoul Natl Univ, Korea Mouse Phenotyping Ctr, Seoul, South Korea; Wayne State Univ, Ctr Mol Med & Genet, Detroit, MI USA; Wayne State Univ, Sch Med, Ctr Integrat Metab & Endocrine Res, Detroit, MI USA; Seoul Natl Univ, Biomax Inst, Seoul, South Korea | ; Park, Ji/ABG-5893-2020; Lee, Yun-Hee/HZI-7224-2023; Kim, Doeun/NJR-1829-2025 | 57210920114; 57195291202; 57202437115; 57219650718; 57216786471; 57221073687; 58680098600; 57221909113; 57221918627; 57221907801; 56428348300; 9238000400; 36738653000; 7004962796; 26643113400; 57209046767; 7005838747; 55176839300 | yunhee.lee@snu.ac.kr; | NATURE METABOLISM | NAT METAB | 2522-5812 | 3 | 3 | SCIE | ENDOCRINOLOGY & METABOLISM | 2021 | 19.89 | 3.1 | 2.52 | 2025-07-30 | 41 | 39 | QUALITY-CONTROL MECHANISMS; ADIPOSE-TISSUE; BROWN-ADIPOCYTES; BEIGE FAT; MITOCHONDRIAL; BNIP3; OBESITY; AUTOPHAGY; PROTEIN; WHITE | Adipocytes; Adipose Tissue, Brown; Adipose Tissue, White; Animals; Cell Line; Energy Metabolism; Humans; Mice; Mice, Knockout; Mitophagy; Obesity; Protein-Serine-Threonine Kinases; Signal Transduction; glucose; insulin; protein BNip3; protein serine threonine kinase; serine threonine protein kinase 3; serine threonine protein kinase 4; small interfering RNA; unclassified drug; protein serine threonine kinase; STK3 protein, human; STK4 protein, human; adipocyte; adipose tissue; animal cell; animal experiment; animal model; animal tissue; Article; beige adipose tissue; bioinformatics; chemoluminescence; confocal microscopy; controlled study; CRISPR-CAS9 system; down regulation; energy expenditure; enzyme linked immunosorbent assay; flow cytometry; gene knockout; gene overexpression; hippo signaling; histology; immunoblotting; immunohistochemistry; lipid diet; liquid chromatography; male; mass spectrometry; mitochondrial respiration; mitophagy; mouse; mouse model; nonhuman; nuclear magnetic resonance imaging; obesity; oxidative phosphorylation; protein expression; protein function; protein phosphorylation; protein stability; real time polymerase chain reaction; site directed mutagenesis; spectrophotometry; upregulation; Western blotting; adipocyte; animal; brown adipose tissue; cell line; energy metabolism; genetics; human; knockout mouse; metabolism; obesity; signal transduction; white adipose tissue | English | 2021 | 2021-03 | 10.1038/s42255-021-00362-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Structural, antioxidant, prebiotic and anti-inflammatory properties of pectic oligosaccharides hydrolyzed from okra pectin by Fenton reaction | To elucidate optimum conditions for the production of pectic oligosaccharides (POSs) with excellent antioxidant, prebiotic, and anti-inflammatory activities, okra pectin (OP) was hydrolyzed by Fenton reaction with different concentrations (3 mM, 5 mM, and 7 mM) of FeSO4. Molecular weight of OP was 112.31 kDa. After Fenton reaction with 3 mM, 5 mM, and 7 mM of FeSO4 (products were named as POS3, POS5, and POS7, respectively), molecular weights were significantly reduced to 6.09 kDa, 4.89 kDa, and 1.79 kDa, respectively. This indicates that Fenton reaction is an efficient way to hydrolyze pectin to obtain POSs. Regarding monosaccharide compositions, FT-IR spectra, and NMR spectra ascertained that ?OH produced by Fenton reaction attacked the homogalacturonan region and neutral side chains of rhamnogalacturonan-I. POSs had higher antioxidant activities (DPPH and ABTS radical scavenging activities) than OP due to their lower molecular weights. POSs also increased the number of probiotics (Lactobacillus rhamnosus ATCC 7469 and Bifidobacterium longum ATCC 15707) and promoted generation of SCFAs. Furthermore, POSs with lower molecular weights inhibited LPS-induced nitrite and inflammatory cytokines (including interleukin (IL)-1? and IL-6) as well as inducible nitric oxide synthase (iNOS)/nuclear factor (NF)-?B signaling axis in RAW 264.7 cells. Therefore, it can be concluded that Fenton reaction can successfully prepare POSs having better biological activities than OP. Among three POSs produced, POS7 had the highest antioxidant and anti-inflammatory activities and good prebiotic capacity. | Yeung, Yuen Kwan; Kang, Yu-Ra; So, Bo Ram; Jung, Sung Keun; Chang, Yoon Hyuk | Kyung Hee Univ, Dept Food & Nutr, Seoul 02447, South Korea; Kyung Hee Univ, Bionanocomposite Res Ctr, Seoul 02447, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | ; Jung, SUNG KEUN/AGR-2623-2022; Kang, Yu-Ra/IUM-6207-2023; Chang, Yoon/AAH-6583-2019 | 57207468078; 57197792821; 57218122440; 35310491400; 36092517300 | yhchang@khu.ac.kr; | FOOD HYDROCOLLOIDS | FOOD HYDROCOLLOID | 0268-005X | 1873-7137 | 118 | SCIE | CHEMISTRY, APPLIED;FOOD SCIENCE & TECHNOLOGY | 2021 | 11.504 | 3.1 | 5.81 | 2025-07-30 | 106 | 109 | Pectic oligosaccharide; Fenton reaction; Antioxidant activity; Prebiotic activity; Anti-inflammatory activity | NF-KAPPA-B; LPS-INDUCED INFLAMMATION; SUGAR-BEET PULP; IN-VITRO; OXIDATIVE STRESS; DEGRADED POLYSACCHARIDES; MACROPHAGES; DEGRADATION; EXTRACTION; PEEL | Anti-inflammatory activity; Antioxidant activity; Fenton reaction; Pectic oligosaccharide; Prebiotic activity | Cell signaling; Hydrolysis; Iron compounds; Molecular weight; Nitric oxide; Nuclear magnetic resonance spectroscopy; Oligosaccharides; Oxidation; Probiotics; Anti-inflammatories; Anti-inflammatory activity; Antioxidant activities; Fenton reactions; Inflammatory properties; Low molecular weight; Optimum conditions; Pectic oligosaccharides; Prebiotic activity; Prebiotics; Antioxidants | English | 2021 | 2021-09 | 10.1016/j.foodhyd.2021.106779 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Towards environmental sustainability in the local community: Future insights for managing the hazardous pollutants at construction sites | Although various technologies are being developed in the construction industry, management technologies for achieving environmental sustainability in the local community are still lacking. As such, this study suggests future insights for the development of an automated intelligent environment management system for the promotion of environmental sustainability in the local community, through a systematic review of 1,707 relevant literature. The systematic review was conducted in two steps: (i) quantitative review: keyword co-occurrence and trend analysis; and (ii) qualitative review: a review on monitoring, evaluation, and improvement technologies. As a result, the research level related to the local-level pollutants (noise, vibration, and dust) was found to be quantitatively insufficient, and the limitations of the existing technologies for these pollutants were presented. Eventually, to overcome these limitations, new technologies and application strategies that can be applied to construction sites as future research roadmap to effectively manage the hazardous pollutants were proposed. Furthermore, an intelligent management system should be developed, and the management of environmental complaints is also necessary for environmental sustainability at the local level in the construction industry. As a fundamental study, this study could become a benchmark for future researches dealing with environmental sustainability and hazardous pollutants in the construction industry. | Hong, Juwon; Kang, Hyuna; An, Jongbaek; Choi, Jinwoo; Hong, Taehoon; Park, Seon; Lee, Dong-Eun | Yonsei Univ, Dept Architecture & Architectural Engn, Seoul, South Korea; Kyungpook Natl Univ, Sch Arch Civil Environm & Energy, Daegu, South Korea | Hong, Taehoon/E-9169-2012 | 57205334533; 57188750703; 57199152502; 57216361641; 57969349700; 55669886900; 56605563300 | juwonae@yonsei.ac.kr;hyuna_kang@yonsei.ac.kr;ajb2577@yonsei.ac.kr;jinwoo818@yonsei.ac.kr;hong7@yonsei.ac.kr;hspark@yonsei.ac.kr;dolee@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 403 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 1.12 | 2025-07-30 | 24 | 28 | Construction industry; Pollutants management; Systematic review; New technology; Application strategy; Intelligent system | GREENHOUSE-GAS EMISSIONS; MULTIOBJECTIVE OPTIMIZATION MODEL; PRECAST CONCRETE INSTALLATION; INDUCED HEARING-LOSS; ENERGY-CONSUMPTION; WASTE MANAGEMENT; EXPOSURE ASSESSMENT; DEMOLITION WASTE; DAMAGE DETECTION; NOISE-POLLUTION | Application strategy; Construction industry; Intelligent system; New technology; Pollutants management; Systematic review | Construction industry; Environmental management; Environmental technology; Hazards; Pollution; Environmental sustainability; Fundamental studies; Hazardous pollutants; Intelligent environment; Intelligent management systems; Management technologies; Technologies and applications; Various technologies; benchmarking; construction industry; environmental impact; future prospect; literature review; management practice; qualitative analysis; strategic approach; sustainability; trend analysis; article; building industry; environmental sustainability; human; noise; pollutant; quantitative analysis; systematic review; vibration; Sustainable development | English | 2021 | 2021-02-05 | 10.1016/j.jhazmat.2020.123804 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Transcriptomic evaluation on methyl bromide-induced phytotoxicity in Arabidopsis thaliana and its mode of phytotoxic action via the occurrence of reactive oxygen species and uneven distribution of auxin hormones | The increase in worldwide trade has caused the quality maintenance of commercialized agriproducts to be crucial in keeping its economic value. In recent years, methyl bromide (MB) has been used dominantly during quarantine and pre-shipment, despite it being an environmental hazard with global repercussions. Through this study, it was shown that Arabidopsis thaliana's 2 h exposure to the MB treatment displayed no signs of phytotoxicity, whereas its 4 h exposure significantly interfered with growth. The transcriptomic analysis found the molecular modifications in A. thaliana after the MB fumigation with the up-regulation of genes specifically relative to the abiotic and oxidative stress, and the down-regulation of auxin transporter genes. Some important gene expressions were verified by RT-qPCR and their expression patterns were similar. Oxidative stresses via the reactive oxygen species (ROS) in relation to MB phytotoxicity were confirmed with the increased malondialdehyde in MB-4h-treated A. thaliana. Uneven distribution of auxins via lower expression of auxin transporter genes was also determined using UPLC-ESI-QqQ MS. Application of two ROS scavengers such as N-acetylcysteine and L-glutathione minimized MB phytotoxic effect in A. thaliana. Therefore, MB caused severe oxidative stress, and alternatives regarding the use of MB should be considered. | Kim, Kyeongnam; Kim, Chaeeun; Park, Jungeun; Jeon, Hwang-ju; Park, Young Ju; Kim, Yoon-Ha; Yang, Jeong Oh; Lee, Sung-Eun | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea; Anim & Plant Quarantine Agcy, Plant Quarantine Technol Ctr, Gimcheon 39660, South Korea | ; Jeon, Hwangju/JDW-9035-2023; Kim, Kyeongnam/KSM-2719-2024 | 57191364349; 57200245142; 58363479900; 56328792200; 57200821541; 57224866763; 8890124100; 55890041600 | selpest@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 419 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 0.15 | 2025-07-30 | 4 | 4 | Quarantine and pre-shipment fumigant; Ozone-depleting substance; Phytotoxicity mechanism; Reactive oxidative stress; Auxin transporters | SINGLET OXYGEN; FUMIGATION; PLANT; ACID; BIOSYNTHESIS; DEGRADATION; GLUTATHIONE; ATMOSPHERE; OXIDATION; EMISSION | Auxin transporters; Ozone-depleting substance; Phytotoxicity mechanism; Quarantine and pre-shipment fumigant; Reactive oxidative stress | Arabidopsis; Arabidopsis Proteins; Gene Expression Regulation, Plant; Hormones; Hydrocarbons, Brominated; Indoleacetic Acids; Reactive Oxygen Species; Transcriptome; Arabidopsis thaliana; Lethrinidae; Amino acids; Gene expression; Oxidative stress; Oxygen; Plants (botany); Polymerase chain reaction; Reactive oxygen species; acetylcysteine; auxin; glutathione; malonaldehyde; methyl bromide; reactive oxygen metabolite; Arabidopsis protein; brominated hydrocarbon; hormone; indoleacetic acid derivative; methyl bromide; reactive oxygen metabolite; transcriptome; Arabidopsis thaliana l; Auxin transporter; Methyl bromide; Ozone depleting substances; Phytotoxicity mechanism; Quarantine and pre-shipment fumigant; Reactive oxidative stress; Reactive oxygen species; Thaliana; Transcriptomics; environmental hazard; food quality; fumigation; genetic analysis; herb; induced response; methyl bromide; phytohormone; phytotoxicity; reactive oxygen species; abiotic stress; Arabidopsis thaliana; Article; controlled study; down regulation; electrospray mass spectrometry; fumigation; gene expression; nonhuman; oxidative stress; phytotoxicity; real time polymerase chain reaction; RNA sequencing; transcriptomics; ultra performance liquid chromatography; upregulation; Arabidopsis; gene expression regulation; genetics; metabolism; Ships | English | 2021 | 2021-10-05 | 10.1016/j.jhazmat.2021.126419 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Algorithm for a cost-reducing time-integration scheme for solving incompressible Navier-Stokes equations | In this paper, we propose a novel trajectory-approximation technique as a time-integration scheme in a semi-Lagrangian framework, which is generally applicable to solve advectional partial differential equations in engineering and physics. The proposed trajectory-approximation technique resolves strong nonlinearity in the Cauchy problem and saves computational costs in comparison with the existing third-order methods by reducing the number of interpolations occurring at every spatial lattice point for each time step. Moreover, an explicit formula is introduced as a more efficient form of the proposed time-integration scheme. To obtain numerical evidence, we apply the proposed method to simulate four benchmark test flows of incompressible Navier-Stokes equations: a linear advection-diffusion, a flow on a square domain, a shear layer flow, and a backward-facing step flow. The proposed method provides third-order accuracy in terms of both time and space in the overall backward semi-Lagrangian methodology. It also demonstrates superior performance over recently developed third-order trajectory-approximation schemes in terms of the efficiency and execution time in solving the Cauchy problem with strong nonlinearity.

| ○ | ○ | Article | Isovalent sulfur substitution to induce a simultaneous increase in the effective mass and weighted mobility of a p-type Bi-Sb-Te alloy: an approach to enhance the thermoelectric performance over a wide temperature range | A significant obstacle to obtaining enhanced thermoelectric performance (defined by a thermoelectric figure of merit, zT) in commercial p-type Bi-Sb-Te alloys is bipolar transport originating from their intrinsic narrow-band-gap semiconducting characteristics. Cation-site doping is commonly used to suppress the bipolar conduction. However, zT enhancement occurs often only at elevated temperatures since the electronic thermal conductivity mainly increases at low temperatures due to the increase of hole concentration. Herein, the substitution of isovalent S ions in the anion Te-site of Bi-Sb-Te is explored to obtain a high zT over a wide temperature range by simultaneously increasing the density-of-states effective mass and weighted mobility. The zT of Bi0.49Cu0.01Sb1.5Te3 is enhanced by similar to 10 % for all measured temperatures, and the average zT increases beyond 1.0 between 300 and 520 K, benefitting from the synergetic control of band structure and deformation potential via S substitution.

| ○ | ○ | Article | Evaluation of engineering properties of expandable foam grout with admixture content | Underground cavities induced by damaged slurry walls or soil erosion in urban areas require suitable repair materials and methods. The objective of this study is to evaluate the strength and stiffness of expandable foam grout (EFG) as a repair material. EFG consists of water, ordinary Portland cement, and admixtures. EFG was prepared at a fixed water-cement ratio of 100% and different admixturecement ratios (AD/Cs), ranging from 0 to 8%. The unit weights of EFGs with different AD/Cs at the slurry and expanded states are measured, and the air contents for both states and the theoretical expansion ratio (ER) are subsequently estimated. Stressstrain curves are obtained using unconfined compressive strength tests to evaluate the unconfined compressive strength and modulus of elasticity. The experimental results show that the air content in the slurry state gradually increases with the AD/C, while the air con -tent in the expanded state and the ER rapidly increased and then converges. The strength and modulus of elasticity increased with curing time, whereas they decreased with increasing AD/C. Based on logarithmic and exponential regression models, the relationships between the strength/modulus, curing time, and AD/C are established with high values of the coefficients of determination. Thus, the relationships pro-posed in this study can be effectively used to predict the strength and modulus of EFG with respect to curing time and AD/C . (c) 2021 Elsevier Ltd.
