| ○ | ○ | Article | Effective synthesis route of renewable nanoporous carbon adsorbent for high energy gas storage and CO2/N2 selectivity | Mandarin peels are fruit by-products and provide an economically viable and renewable carbon source. In order to recycle and convert the bio-waste materials, a scalable synthesis approach for mandarin peel derived porous and activated carbon were designed, and an influence of its preparation conditions such as carbonization, activation temperatures and activating agents was well investigated. The developed nanoporous carbon achieves high textural properties of surface area of similar to 2500 m(2) g(-1) and pore volume of 1.04 cm(3) g(-1) and is naturally doped by sulphur. Owing to a high textural properties and some metal residues, obtained nanoporous carbon exhibited promising sorption properties for all energy carrier gases (e.g. H-2, CH4) and excellent CO2 separation and storage performance, that to the best of our knowledge are among the highest reported values for porous carbons. The H-2 storage capacities at 77 and 298 K and 25 bar were recorded as 6.1 and 0.45 wt%, respectively. For CH4 and CO2 storage at 298 K and 25 bar, uptake of 9.65 and 20.6 mmol g-1 were achieved, respectively. Additionally, the separation of various binary mixtures (CO2/CH4, CH4/N-2 and CO2/N-2) at different composition was studied according to the ideal adsorbed solution theory (IAST) model and a high value of 63 was achieved for CO2/N-2 which is among the top values for nanoporous carbons reported in the literature.

| ○ | ○ | Article | Effects of resveratrol on bone-healing capacity in the mouse tooth extraction socket | Background and Objective After tooth extraction, the extraction socket undergoes several steps of soft and hard tissue healing. The healing process of the extraction socket is modulated by a range of signaling factors and biochemical agents. It has been reported that resveratrol, a polyphenolic compound, exhibits various biological effects, including anti-inflammatory, anti-carcinogenic, antioxidant, and anti-aging effects, and protects cardiovascular and bone tissues. In this study, we examined the cellular effects of resveratrol on human periodontal ligament (hPDL) cells and osteoblast-like (MC3T3-E1) cells and evaluated the bone-healing capacity of tooth extraction sockets in mice. Material and Methods Resveratrol was applied to hPDL and MC3T3-E1 cells to detect cell proliferation and alkaline phosphatase (ALP) activity, and qPCR was employed to understand the gene expression level in vitro. For in vivo experiment, six-week-old C57BL/6 male mice were randomly divided into control (n = 15) and experimental (n = 15) groups and maxillary first molars were extracted by surgery. Experimental groups received 50-mu M resveratrol on extraction sockets and analyzed the degree of new bone formation. Results Treatment of hPDL and MC3T3-E1 cells with resveratrol increased the cell proliferation and ALP activity and enhanced the expression of ALP, BMP-2, BMP-4, and OC genes. Resveratrol enhanced new bone formation in the lingual extraction socket in mice. Conclusion These results suggest that resveratrol increases the cellular physiology of PDL and osteoblast including their proliferation and differentiation and may play an important role in bone-healing capacity after tooth extraction. | Min, Kyung-Kon; Neupane, Sanjiv; Adhikari, Nirpesh; Sohn, Wern-Joo; An, Seo-Young; Kim, Ji-Youn; An, Chang-Hyeon; Lee, Youngkyun; Kim, Yong-Gun; Park, Jin-Woo; Lee, Jae-Mok; Kim, Jae-Young; Suh, Jo-Young | Kyungpook Natl Univ, Sch Dent, Dept Periodontol, IHBR, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Biochem, IHBR, 2177 Dalgubeol Daero, Daegu 41940, South Korea; Daegu Haany Univ, Premajor Cosmet & Pharmaceut, Gyongsan, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral & Maxillofacial Radiol, IHBR, Daegu, South Korea; Gachon Univ, Dept Dent Hyg, Incheon, South Korea | ; Neupane, Sanjiv/I-3470-2018; Kim, Ji-Youn/A-5779-2017; Adhikari, Nirpesh/KEJ-4658-2024 | 57212173657; 56183800400; 57190967936; 44161404800; 55258203200; 57157491000; 17134437600; 36062942200; 55622694400; 56815883000; 17346330000; 56812734700; 7201514992 | jykim91@knu.ac.kr;jysuh@knu.ac.kr; | JOURNAL OF PERIODONTAL RESEARCH | J PERIODONTAL RES | 0022-3484 | 1600-0765 | 55 | 2 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2020 | 4.419 | 13.6 | 0.8 | 2025-06-25 | 25 | 24 | bone formation; drug efficacy; resveratrol; tooth extraction | MORPHOGENETIC PROTEIN-2; CELLS; RAT; DIFFERENTIATION; REGENERATION; GROWTH; SUPPLEMENTATION | bone formation; drug efficacy; resveratrol; tooth extraction | 3T3 Cells; Animals; Humans; Male; Mice; Mice, Inbred C57BL; Osteoblasts; Osteogenesis; Periodontal Ligament; Resveratrol; Tooth Extraction; Tooth Socket; Wound Healing; resveratrol; 3T3 cell line; animal; bone development; C57BL mouse; cytology; drug effect; human; male; mouse; osteoblast; periodontal ligament; tooth extraction; tooth socket; wound healing | English | 2020 | 2020-04 | 10.1111/jre.12710 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article; Proceedings Paper | Hydrophilic nitrogen-doped carbon dots from biowaste using dwarf banana peel for environmental and biological applications | Hydrophilic nitrogen-doped carbon dots (HN-CDs) were produced by a simple hydrothermal method from biowaste, dwarf banana peel. XRD, Raman spectroscopy, and HRTEM analyses confirmed the graphitic structure and narrow size distribution of the HN-CDs. Nitrogen-doping to the carbon structure/framework and owing rich hydrophilic groups on HN-CDs surface were confirmed by XPS and ATR-FTIR spectroscopy techniques. HN-CDs emitted strong and tunable fluorescence (FL) and possessed a good quantum yield (23%). Thus this novel HN-CDs applied as a nanoprobe for the detection of metal ion (Fe3+ ion) in aqueous solution by the fluorometric method. Excessive or lesser amounts of Fe3+ ion in human bodies lead to diverse diseases. Additionally, the accumulation of Fe3+ ion in the environment will escort to a great threat. The prepared HN-CDs selectively and sensitively detect Fe3+ ions by the FL quenching of HN-CDs with a limit of detection of 0.66 mu M in the range of 5-25 mu M. Further, the HN-CDs employed as a biocompatible probe for the multicolor bioimaging in rat liver cells. Also, HN-CDs used as fluorescent ink for drawing and writing. Thus, the biowaste/biomass successfully turned to a useful nanoprobe for environmental protection and health care. | Atchudan, Raji; Edison, Thomas Nesakumar Jebakumar Immanuel; Perumal, Suguna; Muthuchamy, Nallal; Lee, Yong Rok | Yeungnam Univ, Sch Chem Engn, Gyongsan 38541, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Pusan Natl Univ, Dept Chem, Busan 46241, South Korea | Jebakumar Immanuel Edison, Thomas Nesakumar/N-8909-2015; RAJI, ATCHUDAN/C-9904-2017; Nallal, Muthuchamy/O-4449-2016; Lee, Yong/K-6373-2015; Edison, Thomas/N-8909-2015; perumal, suguna/N-9075-2017 | 26648054700; 6506181821; 56673798900; 56845675600; 57330662900 | atchudanr@yu.ac.kr;yrlee@yu.ac.kr; | FUEL | FUEL | 0016-2361 | 1873-7153 | 275 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2020 | 6.609 | 13.6 | 16.4 | 2025-06-25 | 399 | 407 | Biowaste; Hydrothermal method; N-doped carbon dots; Tunable emission; Ferric ion detection; Bioimaging | GRAPHENE QUANTUM DOTS; LABEL-FREE DETECTION; GREEN SYNTHESIS; FLUORESCENT-PROBE; SELECTIVE DETECTION; FE3+ IONS; RAMAN-SPECTROSCOPY; FACILE SYNTHESIS; FRUIT EXTRACT; METAL-ION | Bioimaging; Biowaste; Ferric ion detection; Hydrothermal method; N-doped carbon dots; Tunable emission | Biocompatibility; Carbon; Fluorescence; Fourier transform infrared spectroscopy; Fruits; Hydrophilicity; Metal ions; Metals; Nanoprobes; Nitrogen; Biological applications; Fluorometric method; Graphitic structures; Hydrophilic groups; Hydrothermal methods; Limit of detection; Narrow size distributions; Nitrogen-doped carbons; Doping (additives) | English | 2020 | 2020-09-01 | 10.1016/j.fuel.2020.117821 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Investigation of thermal energy exchange potential of a gravitational water vortex | The conversion of hydel energy of the water vortex formed under gravity is well known in the form of gravitational water vortex turbines; however, the thermal energy exchange potential of the gravitational water vortex flow (GWVF) is yet to be explored. Heat transfer investigation of GWVF is important because the natural gravity being the sole driving force can considerably reduce the pumping power requirement. The present study is the first of its kind to investigate hydro-thermal characteristics of the gravitational water vortex heat exchanger (GWVHE) using an in-house developed experimental test rig. The proposed heat exchanger involves a spiral channel of rectangular cross-section constructed around a cylindrical basin generating a GWVF. For various inlet mass flow rates and temperature combinations, energy balance between the two water streams as well as Nusselt number correlations are determined. Experimentally, a reasonable energy agreement has been achieved with a maximum loss of 30% among the two different inlet temperature tested conditions. Moreover, maximum rise in cold side temperature for the tested conditions was 6K, whereas for the hot side the measure in temperature drop was 8K. A numerical simulation has also been conducted to virtually predict the performance of the designed heat exchanger. The simulation process has shown an improved energy balance with a maximum loss of 10%. A comparison of the experimental and numerical results shows that a GWVF has the potential to effectively exchange the heat between the two fluid streams moving under gravity. The performance of the proposed GWVHE with a pipe in pipe heat exchanger (PPHE) with parallel flow configuration (without vortex) has also been modeled and compared. For the same conditions, the maximum difference in temperature drop and gain between GWVHE and PPHE is 5K and 2.5K, respectively. The present study may act as a benchmark for the new class of GWVF based heat exchangers. (c) 2020 Elsevier Ltd.

| ○ | Article | New class of efficient t2 magnetic resonance imaging contrast agent: Carbon-coated paramagnetic dysprosium oxide nanoparticles | Nanoparticles are considered potential candidates for a new class of magnetic resonance imaging (MRI) contrast agents. Negative MRI contrast agents require high magnetic moments. However, if nanoparticles can exclusively induce transverse water proton spin relaxation with negligible induction of longitudinal water proton spin relaxation, they may provide negative contrast MR images despite having low magnetic moments, thus acting as an efficient T2 MRI contrast agent. In this study, carbon-coated paramagnetic dysprosium oxide (DYO@C) nanoparticles (core = DYO = DyxOy; shell = carbon) were synthesized to explore their potential as an efficient T2 MRI contrast agent at 3.0 T MR field. Since the core DYO nanoparticles have an appreciable (but not high) magnetic moment that arises from fast 4f-electrons of Dy(III) (6H15/2), the DYO@C nanoparticles exhibited an appreciable transverse water proton spin relaxivity (r2) with a negligible longitudinal water proton spin relaxivity (r1). Consequently, they acted as a very efficient T2 MRI contrast agent, as proven from negative contrast enhancements seen in the in vivo T2 MR images. © 2020 by the authors.

| ○ | ○ | Article; Proceedings Paper | One-pot synthesis of Fe3O4@graphite sheets as electrocatalyst for water electrolysis | In this study, Fe3O4@graphite sheets were successfully synthesized in one-pot via a simple hydrothermal method and subsequently employed as an effective electrocatalyst for hydrogen evolution reaction (HER). HER is the crucial electrochemical reactions for the next-generation energy devices. Hydrogen is a clean and renewable energy resource and is one of the most promising candidates for fuel. The shape of the Fe3O4 nanoparticles is nearly spherical with a size of about 10 nm and the Fe3O4 nanoparticles distributed evenly on the graphite sheets. The synthesized Fe3O4@graphite sheets have a specific surface area about 125 m(2) g(-1) with slit-shaped open micro/mesopores. Overall the physicochemical characterization techniques have confirmed the formation, structural stability, and elemental composition of synthesized Fe3O4@graphite sheets. The resulting Fe3O4@graphite sheets were demonstrated towards electrocatalytic HER in 0.1 M KOH solution. The synthesized Fe3O4@graphite sheets delivered the lowest Tafel slope (78 mV dec(-1)) and overpotential (-120 mV(RHE)) at a current density of 10 mA cm(-2). The electrochemical impedance spectroscopy results demonstrate that HER are highly favorable on the Fe3O4@graphite sheets due to the relatively low charge transfer resistance. The experimental results reveal that Fe3O4@graphite sheets possess remarkable electrocatalytic HER activities and are highly stable. The good electrocatalytic activity of Fe3O4@graphite sheet can be ascribed to the synergistic effect between Fe3O4 and graphite sheets, which can facilitate charge transfer kinetics to enhance electrocatalytic HER performance. | Atchudan, Raji; Edison, Thomas Nesakumar Jebakumar Immanuel; Perumal, Suguna; Vinodh, Rajangam; Muthuchamy, Nallal; Lee, Yong Rok | Yeungnam Univ, Sch Chem Engn, Gyongsan 38541, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Pusan Natl Univ, Sch Elect & Comp Engn, Busan 46241, South Korea; Pusan Natl Univ, Dept Chem, Busan 46241, South Korea | RAJI, ATCHUDAN/C-9904-2017; Nallal, Muthuchamy/O-4449-2016; Jebakumar Immanuel Edison, Thomas Nesakumar/N-8909-2015; perumal, suguna/N-9075-2017; Edison, Thomas/N-8909-2015; Lee, Yong/K-6373-2015 | 26648054700; 57210289891; 56673798900; 35727964800; 56845675600; 57330662900 | atchudanr@yu.ac.kr;yrlee@yu.ac.kr; | FUEL | FUEL | 0016-2361 | 1873-7153 | 277 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2020 | 6.609 | 13.6 | 1.65 | 2025-06-25 | 42 | 42 | Fe3O4 nanoparticle; Graphite sheet; Water splitting; Hydrogen evolution reaction; Renewable fuel | HYDROGEN EVOLUTION REACTION; DOPED CARBON DOTS; REDUCED GRAPHENE OXIDE; FLUORESCENT-PROBE; FACILE SYNTHESIS; SOLVOTHERMAL ROUTE; NANOPARTICLES; COMPOSITE; FE3O4; FABRICATION | Fe<sub>3</sub>O<sub>4</sub> nanoparticle; Graphite sheet; Hydrogen evolution reaction; Renewable fuel; Water splitting | Charge transfer; Electrocatalysts; Electrochemical impedance spectroscopy; Graphite; Hydrogen evolution reaction; Hydrogen fuels; Iron oxides; Nanoparticles; Potassium hydroxide; Renewable energy resources; Stability; Charge transfer kinetics; Charge transfer resistance; Electrocatalytic activity; Electrochemical reactions; Elemental compositions; Hydrothermal methods; Physico-chemical characterization; Structural stabilities; Magnetite | English | 2020 | 2020-10-01 | 10.1016/j.fuel.2020.118235 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Preliminary experimental study on multi-stage gravitational water vortex turbine in a conical basin | Gravitational water vortex turbine (GWVT) is an ultra-low head turbine that extracts energy from an artificially induced gravitational water vortex in the basin of cylindrical or conical configuration. The latter type of basin helps in the re-construction of vortex once it is distorted after passing through a runner and thus, provide an additional potential for power extraction at different heights along the basin. In the absence of a detailed experimental study on multi-staging of GWVT in a conical basin, a preliminary investigation has been carried out using runners of Savonius type blades and producing power independently because of telescopic shafts arrangement. The effects of crucial design parameters such as rotor diameter to basin diameter ratio (RB), vortex-blade interaction, the position of the various stages and the offset distance between the neighboring stages, on the performance of GWVT are reported. In addition, the performance parameters which include rotational speed, torque and power are investigated under various rotor submergence conditions; thus, revealing maximum performance for a brimming vortex-blade interaction. One of the key findings of the study is the complex transfer of energy between the two neighboring stages through the vortex flow without the physical contact of rotors. Moreover, multi-staging provides more power than single-stage GWVT by strengthening the vortex in the vicinity of each other through rigid body rotation of the neighboring runners. The outcomes of the present study make it a potential benchmark for the future generations of GWVT technology. (C) 2019 Elsevier Ltd.

| ○ | ○ | Article | Relaxation oscillations and frequency entrainment in quantum mechanics | Frequency entrainment of continuous-variable oscillators has to date been restrained to the weakly nonlinear regime. Here we overcome this bottleneck and extend frequency entrainment of quantum continuous-variable oscillators to arbitrary nonlinearities. The previously known steady state of such quantum oscillators in the weakly nonlinear regime (also known as a Stuart-Landau oscillator) is shown to emerge as a special case. Most importantly, the hallmark of strong nonlinearity-relaxation oscillations-is shown in quantum mechanics. Depending on the oscillator's nonlinearity, relaxation oscillations are found to occur via two distinct mechanisms in phase space. | Chia, A.; Kwek, L.

| ○ | ○ | Article | Removal of nitrogen-containing compounds from microalgae derived biofuel by adsorption over functionalized metal organic frameworks | Considering the depletion of fossil fuel, alternative energy resources have been continuously investigated. Microalgae-derived biofuel can be a solution to replace traditional fuel; however, biofuel contains much nitrogen-containing compounds (NCCs) such as carbazole (CBZ) and benzonitrile (PhCN). In this work, effective denitrogenation of biofuel was investigated by using MOFs, especially having multi-functional groups and high porosity. MIL-101-NH2 was modified with oxalyl chloride (OC) to have a MOF called M101-OC. The M101-OC showed remarkable performance in adsorptive denitrogenation from biofuel. Or, M101-OC had 3.8- and 19.6times adsorption capacity for CBZ and PhCN that of activated carbon, respectively; and showed the highest adsorption capacity, compared with any known adsorbent. The noticeable performances of M101-OC could be explained with hydrogen bonding due to ample hydrogen donor and hydrogen acceptor sites on the M101-OC. Finally, the investigated MOF was also easily recycled via simple ethanol washing. Therefore, M101-OC might be a promising adsorbent for the purification of microalgae-derived biofuel having much NCCs. | Mondol, Md Mahmudul Hassan; Bhadra, Biswa Nath; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Bhadra, Biswa Nath/ABG-6935-2021; Bhadra, Biswa/ABG-6935-2021; Hassan Mondol, Md Mahmudul/AAM-8718-2021; Jhung, Sung/AAO-6683-2021 | 57217989090; 56982844300; 6701659467 | sung@knu.ac.kr; | FUEL | FUEL | 0016-2361 | 1873-7153 | 280 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2020 | 6.609 | 13.6 | 1.92 | 2025-06-25 | 39 | 39 | Adsorption; Algae-derived fuel; Denitrogenation; Functionalization; MOF | ACID-BASE INTERACTIONS; DOPED POROUS CARBONS; REMARKABLE ADSORBENT; MODEL FUEL; BIO-OIL; DENITROGENATION; MIL-101; DESULFURIZATION; QUINOLINE; INDOLE | Adsorption; Algae-derived fuel; Denitrogenation; Functionalization; MOF | Activated carbon; Adsorption; Algae; Aromatic compounds; Chlorine compounds; Fossil fuel deposits; Fossil fuels; Hydrogen; Hydrogen bonds; Metal-Organic Frameworks; Microorganisms; Nitrogen removal; Organometallics; Adsorption capacities; Adsorptive denitrogenation; Alternative energy resources; Denitrogenation; Functionalized; Hydrogen acceptor; Oxalyl chloride; Traditional fuels; Biofuels | English | 2020 | 2020-11-15 | 10.1016/j.fuel.2020.118622 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Risk factors for disease progression in low-teens normal-tension glaucoma | Background/Aims To investigate the risk factors for disease progression of normal-tension glaucoma (NTG) with pretreatment intraocular pressure (IOP) in the low-teens. Methods One-hundred and two (102) eyes of 102 patients with NTG with pretreatment IOP <= 12 mm Hg who had been followed up for more than 60 months were retrospectively enrolled. Patients were divided into progressor and non-progressor groups according to visual field (VF) progression as correlated with change of optic disc or retinal nerve fibre layer defect. Baseline demographic and clinical characteristics including diurnal IOP and 24 hours blood pressure (BP) were compared between the two groups. The Cox proportional hazards model was used to identify the risk factors for disease progression. Results Thirty-six patients (35.3%) were classified as progressors and 66 (64.7%) as non-progressors. Between the two groups, no significant differences were found in the follow-up periods (8.7 +/- 3.4 vs 7.7 +/- 3.2 years; p=0.138), baseline VF mean deviation (-4.50 +/- 5.65 vs -3.56 +/- 4.30 dB; p=0.348) or pretreatment IOP (11.34 +/- 1.21 vs 11.17 +/- 1.06 mm Hg; p=0.121). The multivariate Cox proportional hazards model indicated that greater diurnal IOP at baseline (HR=1.609; p=0.004), greater fluctuation of diastolic BP (DBP; HR=1.058; p=0.002) and presence of optic disc haemorrhage during follow-up (DH; HR=3.664; p=0.001) were risk factors for glaucoma progression. Conclusion In the low-teens NTG eyes, 35.3% showed glaucoma progression during the average 8.7 years of follow-up. Fluctuation of DBP and diurnal IOP as well as DH were significantly associated with greater probability of disease progression. | Baek, Sung Uk; Ha, Ahnul; Kim, Dai Woo; Jeoung, Jin Wook; Park, Ki Ho; Kim, Young Kook | Hallym Univ, Coll Med, Dept Ophthalmol, Anyang, South Korea; Hallym Univ, Sacred Heart Hosp, Dept Ophthalmol, Anyang, South Korea; Seoul Natl Univ, Dept Ophthalmol, Coll Med, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Ophthalmol, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Ophthalmol, Daegu, South Korea | Park, Ki-Ho/MYQ-9501-2025; Ha, Ahnul/ABD-1589-2020; Kim, You Sun/B-2881-2015 | 57202379043; 57189002120; 57095192800; 9640226000; 56276582800; 55908959500 | md092@naver.com; | BRITISH JOURNAL OF OPHTHALMOLOGY | BRIT J OPHTHALMOL | 0007-1161 | 1468-2079 | 104 | 1 | SCIE | OPHTHALMOLOGY | 2020 | 4.638 | 13.7 | 1.6 | 2025-06-25 | 20 | 20 | low-teens; normal-tension glaucoma; glaucoma progression; risk factors | VISUAL-FIELD PROGRESSION; OPEN-ANGLE GLAUCOMA; OCULAR BLOOD-FLOW; INTRAOCULAR-PRESSURE; DIURNAL-VARIATION; FLUCTUATION; IMPACT | glaucoma progression; low-teens; normal-tension glaucoma; risk factors | Adult; Aged; Blood Pressure; Blood Pressure Monitoring, Ambulatory; Circadian Rhythm; Disease Progression; Female; Follow-Up Studies; Humans; Intraocular Pressure; Low Tension Glaucoma; Male; Middle Aged; Optic Nerve Diseases; Prognosis; Proportional Hazards Models; Retinal Hemorrhage; Retrospective Studies; Risk Factors; Visual Fields; Young Adult; adult; aged; Article; circadian rhythm; diastolic blood pressure; disease classification; disease exacerbation; female; follow up; human; intraocular hemorrhage; intraocular pressure; low teens normal tension glaucoma; low tension glaucoma; major clinical study; male; optic disk; optic disk hemorrhage; priority journal; risk factor; visual field; blood pressure; blood pressure monitoring; complication; disease exacerbation; low tension glaucoma; middle aged; optic nerve disease; pathophysiology; physiology; procedures; prognosis; proportional hazards model; retina hemorrhage; retrospective study; young adult | English | 2020 | 2020-01 | 10.1136/bjophthalmol-2018-313375 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Drought-induced AtbZIP62 transcription factor regulates drought stress response in Arabidopsis | We investigated the role of AtbZIP62, an uncharacterized Arabidopsis bZIP TF, in oxidative, nitro-oxidative and drought stress conditions using reverse genetics approach. We further monitored the expression of AtPYD1 gene (orthologous to rice OsDHODH1 involved in the pyrimidine biosynthesis) in atbzip62 knock-out (KO) plants in order to investigate the transcriptional interplay of AtbZIP62 and AtPYD1. The atbzip62 KO plants showed significant increase in shoot length under oxidative stress, while no significant difference was recorded for root length compared to WT. However, under nitro-oxidative stress conditions, atbzip62 showed differential response to both NO-donors. Further characterization of AtbZIP62 under drought conditions showed that both atbzip62 and atpyd1-2 showed a sensitive phenotype to drought stress, and could not recover after re-watering. Transcript accumulation of AtbZIP62 and AtPYD1 showed that both were highly up-regulated by drought stress in wild type (WT) plants. Interestingly, AtPYD1 transcriptional level significantly decreased in atbzip62 exposed to drought stress. However, AtbZIP62 expression was highly induced in atpyd1-2 under the same conditions. Both AtbZIP62 and AtPYD1 were up-regulated in atnced3 and atcat2 while showing a contrasting expression pattern in atgsnor13. The recorded increase in CAT, POD, and PPO-like activities, the accumulation of chlorophylls and total carotenoids, and the enhanced proline and malondialdehyde levels would explain the sensitivity level of atbzip62 towards drought stress. All results collectively suggest that AtbZIP62 could be involved in AtPYD1 transcriptional regulation while modulating cellular redox state and photosynthetic processes. In addition, AtbZIP62 is suggested to positively regulate drought stress response in Arabidopsis. | Rolly, Nkulu Kabange; Imran, Qari Muhammad; Shahid, Muhammad; Imran, Muhammad; Khan, Murtaza; Lee, Sang-Uk; Hussain, Adil; Lee, In-Jung; Yun, Byung-Wook | Kyungpook Natl Univ, Sch Appl Biosci, Lab Plant Funct Genom, Daegu, South Korea; Minist Agr, Natl Lab Seed Testing, Natl Seed Serv, SENASEM, Kinshasa, DEM REP CONGO; Kyungpook Natl Univ, Sch Appl Biosci, Lab Crop Physiol, Daegu, South Korea; Abdul Wali Khan Univ, Dept Agr, Mardan 23200, KP, Pakistan | Imran, Qari Muhammad/ABG-6074-2022; Hussain, Adil/K-6016-2018; Hussain, Dr. Adil/K-6016-2018; KABANGE, NKULU/AAQ-9425-2020; Shahid, Muhammad/AAE-9424-2020; Lee, In-Jung/GLS-0432-2022; Imran, Muhammad/AFL-6590-2022 | 57202031236; 55849263700; 59577718600; 58282433800; 57207990116; 57203597131; 41961162600; 16425830900; 8245123600 | rolly.kabange@gmail.com;mimranbot@gmail.com;shahidariswat@gmail.com;m.imran02@yahoo.com;murtazakhan.bio@gmail.com;2sanguk.c@gmail.com;adilhussain@awkum.edu.pk;ijlee@knu.ac.kr;bwyun@knu.ac.kr; | PLANT PHYSIOLOGY AND BIOCHEMISTRY | PLANT PHYSIOL BIOCH | 0981-9428 | 1873-2690 | 156 | SCIE | PLANT SCIENCES | 2020 | 4.27 | 13.8 | 2.31 | 2025-06-25 | 42 | 46 | AtbZIP62; AtPYD1; Drought tolerance; Phytohormones; Nitric oxide; Arabidopsis | NITRIC-OXIDE; PROLINE ACCUMULATION; OXIDATIVE STRESS; GENE-EXPRESSION; ACID; PLANTS; BIOSYNTHESIS; TOLERANCE; RICE; SALT | Arabidopsis.; AtbZIP62; AtPYD1; Drought tolerance; Nitric oxide; Phytohormones | Arabidopsis; Arabidopsis Proteins; Droughts; Gene Expression Regulation, Plant; Plants, Genetically Modified; Stress, Physiological; Transcription Factors; Arabidopsis protein; transcription factor; Arabidopsis; drought; gene expression regulation; genetics; physiological stress; physiology; transgenic plant | English | 2020 | 2020-11 | 10.1016/j.plaphy.2020.09.013 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Bar Classification Based on the Potential Map | We introduce a new approach to classify barred galaxies that utilizes the transverse-to-radial force ratio map (ratio map, hereafter) in a different manner from previous studies. When we display the ratio map in polar coordinates, barred galaxies appear as four aligned, horizontal thick slabs. This characteristic feature enables us to successfully classify barred and nonbarred galaxies with an accuracy of 87%. It yields a bar fraction of 53%, including both SBs and SABs, when applied to 884 nearby (z < 0.01) spiral galaxies from the Sloan Digital Sky Survey/DR7. It also provides the bar strength and length measurements, in particular, separated from the spiral arms. They show good correlations with the measures estimated from ellipse fitting and Fourier analysis. However, we find different tendencies of the bar strength measurements in terms of the Hubble sequence: as the Hubble sequence increases (toward late types), the bar strength and bar ellipticity increase, whereas the dipole Fourier amplitude decreases. We show that the bulge affects the estimation of the bar strength differently, depending on the classification methods. The bulge causes the bar length to be overestimated in all three methods. Meanwhile, we find that barred galaxies show two types of radial profiles of the angle-averaged force ratio: one has a maximum peak (type M) and the other a plateau (type P). Comparison with numerical simulations suggests that type-M bars are more mature than type-P bars in terms of evolutionary stage. | Lee, Yun Hee; Park, Myeong-Gu; Ann, Hong Bae; Kim, Taehyun; Seo, Woo-Young | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Res & Training Team Future Creat Astrophysicists, BK21 Plus Program, Daegu 41566, South Korea; Pusan Natl Univ, Dept Earth Sci Educ, Busan 46241, South Korea; Chungbuk Natl Univ, Dept Phys, Cheongju 28644, South Korea | 57206855558; 7404490321; 55880768900; 57050549000; 58632986300 | mgp@knu.ac.kr; | ASTROPHYSICAL JOURNAL | ASTROPHYS J | 0004-637X | 1538-4357 | 899 | 1 | SCIE | ASTRONOMY & ASTROPHYSICS | 2020 | 5.877 | 14.0 | 0.14 | 2025-06-25 | 16 | 3 | Galaxy classification systems; Galaxy properties; Galaxy structure; Galaxy evolution | INFRARED SURFACE PHOTOMETRY; STAR-FORMATION RATES; SPIRAL GALAXIES; GRAVITATIONAL TORQUES; DOMINATED GALAXIES; GALACTIC DISK; MASS DENSITY; DUST LANES; MORPHOLOGY; GAS | English | 2020 | 2020-08 | 10.3847/1538-4357/aba4a4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Dual AGN Candidates with Double-peaked [O iii] Lines Matching that of Confirmed Dual AGNs | We have performed a spectral decomposition to search for dual active galactic nuclei (DAGNs) in the Sloan Digital Sky Survey (SDSS) quasars with z iii] lines of known DAGNs. Out of 1271 SDSS quasars, we have identified 77 DAGN candidates. Optical and mid-infrared (MIR) diagnostic diagrams are used to investigate the ionizing source in the DAGN candidates. The optical diagnostic analysis suggests 93% of them are powered by AGNs, and MIR diagnostic analysis suggests 97% are powered by AGNs. About one-third of the SDSS images of the DAGN candidates show signs of tidal interaction, but we are unable to identify double nuclei in most of them due to the low spatial resolution of the archival imaging data available for most of the sample. The radio-loud fraction of the DAGN candidates (similar to 10%) is similar to that of typical AGNs. | Kim, D. -C.; Yoon, Ilsang; Evans, A.

| ○ | ○ | Article | Gemini Multi-Object Spectrograph Integral Field Unit Spectroscopy of the Double-peaked Broad Emission Line of a Red Active Galactic Nucleus | Galaxy mergers are expected to produce multiple supermassive black holes (SMBHs) in close-separation, but the detection of such SMBHs has been difficult. 2MASS J165939.7 + 183436 is a red active galactic nucleus (AGN) that is a prospective merging SMBH candidate owing to its merging features in Hubble Space Telescope imaging and double-peaked broad emission lines (BELs). Herein, we report a Gemini Multi-Object Spectrograph Integral Field Unit observation of a double-peaked broad H alpha line of 2MASS J165939.7+183436. Furthermore, we confirm the existence of two BEL peaks that are kinematically separated by 3000 km s(-1), with the SMBH of each BEL component weighing at and 01; however, under several plausible assumptions regarding the fitting of each spaxel, the two components are found to be spatially separated at 0085 (similar to 250 pc). Different assumptions for the fitting can lead to a null (<005) or a larger spatial separation (similar to 015). Given the uncertainty regarding the spatial separation, various models, such as the disk emitter and multiple SMBH models, are viable solutions to explain the double BEL components. These results will promote future research for finding more multiple SMBH systems in red AGNs, and higher-resolution imaging validates these different models. | Kim, Dohyeong; Im, Myungshin; Kim, Minjin; Ho, Luis C. | Peking Univ, Kavli Inst Astron & Astrophys, Beijing 100871, Peoples R China; Seoul Natl Univ, Dept Phys & Astron, Astron Program, CEOU, Seoul 151742, South Korea; Seoul Natl Univ, Dept Phys & Astron, Astron Program, Seoul 151742, South Korea; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 702701, South Korea; Korea Astron & Space Sci Inst, Daejeon 305348, South Korea; Peking Univ, Sch Phys, Dept Astron, Beijing 100871, Peoples R China | ; Kim, Minjin/AAU-9910-2020; Im, Myungshin/B-3436-2013 | 55574223678; 7004267711; 56898213300; 35229428100 | dh.dr2kim@gmail.com;mim@astro.snu.ac.kr; | ASTROPHYSICAL JOURNAL | ASTROPHYS J | 0004-637X | 1538-4357 | 894 | 2 | SCIE | ASTRONOMY & ASTROPHYSICS | 2020 | 5.877 | 14.0 | 0.34 | 2025-06-25 | 8 | 9 | Active galactic nuclei; Supermassive black holes; Galaxy evolution; Galaxy mergers; Galaxies; Quasars; Galaxy nuclei; Gravitational wave sources; Astrophysical black holes | SUPERMASSIVE BLACK-HOLES; ELLIPTIC GALAXIES; QUASAR; MASS; COEVOLUTION; MERGERS; SEARCH; SAMPLE; DISK; AGN | English | 2020 | 2020-05 | 10.3847/1538-4357/ab86a4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
