○ ○ Article ⓘ Fursultiamine Alleviates Choroidal Neovascularization by Suppressing Inflammation and Metabolic Reprogramming ⓘ PURPOSE. To assess the therapeutic effects of fursultiamine on choroidal neovascularization (CNV) through its modulation of inflammation and metabolic reprogramming in the retinal pigment epithelium (RPE). METHODS. The anti-angiogenic effects of fursultiamine were assessed by measuring vascular leakage and CNV lesion size in the laser-induced CNV mouse model. Inflammatory responses were evaluated by quantitative polymerase chain reaction, western blot, and ELISA in both CNV eye tissues and in vitro cell cultures using ARPE-19 cells or primary human RPE (hRPE) cells under lipopolysaccharide (LPS) treatment or hypoxia. Mitochondrial respiration was assessed by measuring oxygen consumption in ARPE-19 cells treated with LPS with or without fursultiamine, and lactate production was measured in ARPE-19 cells subjected to hypoxia with or without fursultiamine. RESULTS. In laser-induced CNV, fursultiamine significantly decreased vascular leakage and lesion size, as well as the numbers of both choroidal and retinal inflammatory cytokines, including IL-1 beta, IL-6, IL-8, and TNF-alpha. In LPS-treated ARPE-19 cells, fursultiamine decreased proinflammatory cytokine secretion and nuclear factor kappa B phosphorylation. Furthermore, fursultiamine suppressed LPS-induced upregulation of IL-6, IL-8, and monocyte chemoattractant protein-1 in a dose-dependent and time-dependent manner in primary hRPE cells. Interestingly, fursultiamine significantly enhanced mitochondrial respiration in the LPS-treated ARPE-19 cells. Additionally, fursultiamine attenuated hypoxia-induced aberrations, including lactate production and inhibitory phosphorylation of pyruvate dehydrogenase. Furthermore, fursultiamine attenuated hypoxia-induced VEGF secretion and mitochondrial fission in primary hRPE cells that were replicated in ARPE-19 cells. CONCLUSIONS. Our findings show that fursultiamine is a viable putative therapeutic for neovascular age-related macular degeneration by modulating the inflammatory response and metabolic reprogramming by enhancing mitochondrial respiration in the RPE. ⓘ Do, Ji Yeon; Kim, Juhee; Kim, Mi-Jin; Lee, Jung Yi; Park, So-Young; Yanai, Ryoji; Lee, In-Kyu; Park, Sungmi; Park, Dong Ho ⓘ Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Leading Edge Res Ctr Drug Discovery & Dev Diabet, 807 Hoguk Ro, Daegu 41404, South Korea; JD Biosci Inc, R&D Ctr, Gwangju, South Korea; Kyungpook Natl Univ, Coll Pharm, Daegu, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu, South Korea; Yamaguchi Univ, Dept Ophthalmol, Grad Sch Med, Ube, Yamaguchi, Japan; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Ophthalmol, 130 Dongdeok Ro, Daegu 41944, South Korea ⓘ Lee, Sang-Jun/A-3892-2015; Lee, In-Kyu/AAR-6374-2021 ⓘ 57219717994; 59291644500; 56984392800; 57195563161; 57211630074; 7005523093; 36071537600; 56252420000; 36676632900 ⓘ smpark93@gmail.com;dongho_park@knu.ac.kr; ⓘ INVESTIGATIVE OPHTHALMOLOGY & VISUAL SCIENCE ⓘ INVEST OPHTH VIS SCI ⓘ 0146-0404 1552-5783 61 12 SCIE OPHTHALMOLOGY ⓘ 2020 4.799 12.1 1.07 2025-06-25 ⓘ 13 13 choroidal neovascularization; inflammation; metabolic reprogramming; mitochondria; fursultiamine ⓘ RETINAL-PIGMENT EPITHELIUM; BIOAVAILABILITY ASSESSMENT; GENE-EXPRESSION; RPE; THIAMINE; BENFOTIAMINE; HIF-1-ALPHA; IL-8; DEGENERATION; MACROPHAGES ⓘ Choroidal neovascularization; Fursultiamine; Inflammation; Metabolic reprogramming; Mitochondria ⓘ Animals; Blotting, Western; Capillary Permeability; Cell Line; Cellular Reprogramming Techniques; Chemokine CCL2; Choroidal Neovascularization; Choroiditis; Disease Models, Animal; Dose-Response Relationship, Drug; Enzyme-Linked Immunosorbent Assay; Fursultiamin; Inflammation; Interleukin-6; Interleukin-8; Lipopolysaccharides; Male; Mice; Mice, Inbred C57BL; Real-Time Polymerase Chain Reaction; Retinal Pigment Epithelium; Vitamin B Complex; fluorescein sodium; fursultiamine; interleukin 1beta; interleukin 6; interleukin 8; lipopolysaccharide; tumor necrosis factor; Ccl2 protein, mouse; fursultiamine; interleukin 6; interleukin 8; interleukin-6, mouse; lipopolysaccharide; monocyte chemotactic protein 1; vitamin B complex; animal experiment; animal model; ARPE-19 cell line; Article; controlled study; enzyme linked immunosorbent assay; human; human cell; hypoxia; immunoblotting; inflammation; liquid chromatography-mass spectrometry; live cell imaging; male; mitochondrial biogenesis; mouse; nonhuman; oxidative stress; oxygen consumption rate; polymerase chain reaction; priority journal; protein expression; real time polymerase chain reaction; retinal pigment epithelium; RNA extraction; subretinal neovascularization; Western blotting; animal; C57BL mouse; capillary permeability; cell line; cell reprogramming technique; choroiditis; disease model; dose response; drug effect; inflammation; metabolism; subretinal neovascularization ⓘ English 2020 2020-10 10.1167/iovs.61.12.24 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Impact of Anatomic Extent of Nodal Metastasis on Adjuvant Chemotherapy Outcomes in Stage III Colon Cancer ⓘ BACKGROUND: An oxaliplatin-based chemotherapy regimen improves the survival outcomes of patients with stage III colon cancer. However, its complications are well-known. OBJECTIVE: The purpose of this study was to distinguish between the survival outcomes of patients who underwent curative resection for stage III colon cancer with oxaliplatin chemotherapy and those who underwent such resection without oxaliplatin chemotherapy. DESIGN: This was a retrospective analytical study based on prospectively collected data. SETTINGS: This study used data on patients who underwent surgery at our hospital between January 2010 and December 2014. PATIENTS: A cohort of 254 consecutive patients who underwent curative resection for stage III colon cancer was included in this study. The patients were divided into 2 groups: patients with isolated pericolic lymph node metastasis (n = 175) and those with extrapericolic lymph node metastasis (n = 79). MAIN OUTCOME MEASURES: Clinicopathologic features and 3-year survival outcomes were analyzed with and without oxaliplatin therapy in the pericolic lymph node group. RESULTS: The pericolic lymph node group showed significantly improved overall survival compared with the extrapericolic lymph node group at a median follow-up of 48.5 months (95.8% vs 77.8%;p< 0.001). In contrast, there was no significant difference in overall survival (99.0% vs 92.0%;p= 0.137) and disease-free survival (89.1% vs 88.2%;p= 0.460) between the oxaliplatin and nonoxaliplatin subgroups of the pericolic lymph node group. Multivariate analysis showed that the administration of oxaliplatin chemotherapy to the pericolic lymph node group did not lead to a significant difference in the overall survival (p= 0.594). LIMITATIONS: The study was limited by its retrospective design and single institutional data analysis. CONCLUSIONS: This study suggests that the anatomic extent of metastatic lymph nodes could affect patient prognosis, and the effect of oxaliplatin-based adjuvant chemotherapy may not be prominent in stage III colon cancer with isolated pericolic lymph node metastasis. ⓘ Woo, In Teak; Park, Jun Seok; Kang, Byung Woog; Park, Soo Yeun; Kim, Hye Jin; Choi, Gyu-Seog; Gwang Kim, Jong ⓘ Soonchunhyang Univ Hosp, Dept Surg, Gumi, South Korea; Kyungpook Natl Univ Hosp, Dept Colorectal Surg, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Oncol Hematol, Daegu, South Korea ⓘ Kim, Hye/W-1059-2019; Park, Joonhong/AAZ-9885-2020 ⓘ 57196472276; 35226761100; 28567838500; 40561578300; 57204567554; 8058759100; 6503932178 ⓘ parkjs0802@knu.ac.kr; ⓘ DISEASES OF THE COLON & RECTUM ⓘ DIS COLON RECTUM ⓘ 0012-3706 1530-0358 63 10 SCIE GASTROENTEROLOGY & HEPATOLOGY;SURGERY ⓘ 2020 4.785 12.1 0 2025-06-25 ⓘ 0 0 Adjuvant chemotherapy; Colon cancer; Lymph nodes; Metastasis; Oxaliplatin ⓘ INDIVIDUAL PATIENT DATA; MODIFIED FOLFOX6; POOLED ANALYSIS; SIGMOID COLON; LYMPH-NODES; OXALIPLATIN; SURVIVAL; THERAPY; FLUOROURACIL; LEUCOVORIN ⓘ Adjuvant chemotherapy; Colon cancer; Lymph nodes; Metastasis; Oxaliplatin ⓘ Aged; Antineoplastic Combined Chemotherapy Protocols; Capecitabine; Chemotherapy, Adjuvant; Colonic Neoplasms; Female; Fluorouracil; Humans; Leucovorin; Lymphatic Metastasis; Male; Middle Aged; Neoplasm Staging; Organoplatinum Compounds; Oxaloacetates; Prognosis; Retrospective Studies; Risk Factors; Survival Rate; antineoplastic agent; capecitabine; fluorouracil; folinic acid; oxaloacetic acid derivative; platinum complex; adjuvant chemotherapy; aged; cancer staging; colon tumor; female; human; lymph node metastasis; male; middle aged; mortality; pathology; prognosis; retrospective study; risk factor; survival rate ⓘ English 2020 2020-10 10.1097/dcr.0000000000001790 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Indocyanine Green Fluorescence Imaging-Guided Laparoscopic Surgery Could Achieve Radical D3 Dissection in Patients With Advanced Right-Sided Colon Cancer ⓘ BACKGROUND: The optimal lymph node dissection with central vascular ligation is an important part for oncological outcomes after laparoscopic right-sided colon cancer surgery. Few studies have examined the clinical value of indocyanine green fluorescence imaging-guided D3 dissection for right-sided colon cancer. OBJECTIVES: We assessed the clinical value of indocyanine green fluorescence imaging-guided laparoscopic surgery in improving the radicality of lymph node dissection for right-sided colon cancer by comparing the outcomes of conventional laparoscopic surgery. DESIGN: The data were retrospectively reviewed and analyzed. SETTING: This study was conducted at a single university hospital. PATIENTS: A 1:2 matched case-control study included 25 patients undergoing fluorescence imaging-guided laparoscopic surgery and 50 patients undergoing conventional laparoscopic surgery for clinical T3 or T4 right-sided colon cancer between June 2016 and December 2017. MAIN OUTCOME MEASURES: The extent of D3 dissection and pathological results (tumor stage, lymph node yield, and number of metastatic lymph nodes) were analyzed. RESULTS: The 2 groups were similar in baseline characteristics. The numbers of harvested pericolic and intermediate lymph nodes were not different between the 2 groups. The numbers of central lymph nodes (14 vs 7, p < 0.001) and total harvested lymph nodes (39 vs 30, p = 0.003) were significantly higher in the fluorescence group than in the conventional group. In the multivariate analysis, the use of indocyanine green fluorescence imaging was an independently related factor for the retrieval of higher numbers of overall and central lymph nodes. The number of metastatic lymph nodes was not significantly different between the 2 groups. LIMITATIONS: The results of this study were limited by its small patient numbers and retrospective nature. CONCLUSIONS: Real-time indocyanine green fluorescence imaging of lymph nodes may improve the performance of more radical D3 lymph node dissection during laparoscopic right hemicolectomy for advanced right-sided colon cancer.

○ ○ Article ⓘ Roles of local reactivity on the solid-state addition reaction kinetics ⓘ A predominant factor of the diffusion-controlled kinetics of a solid-state addition reaction using powder is the particle size of the reactants, into which the other chemical species are migrating. However, diffusion-controlled kinetic equations are seldom satisfactorily applicable even when the effects of particle size are thoroughly accounted. One of the representative nongeometrical items affecting the solid-state reaction process is the reactivity of solids (ROS), which has not been accounted in any of the established kinetic equations. Change in ROS is the consequence of the imperfections of the crystalline solids. In this study, we try to discuss the effects of ROS on the solid-state reaction kinetics. A typical solid-state addition reaction, formation of BaTiO(3)from the equimolar mixture of TiO(2)and BaCO3, was chosen as a model. For this reaction, the rate-determining step is established to be the diffusion of Ba(2+)ions into TiO2. Since the defect concentration is known to be higher at the near-surface region, the local distribution of ROS that is discussed here is based on a simple core-shell model of the host TiO(2)particles with higher reactivity at the shell part. The ratio of the rate of diffusion within the shell part relative to that of the core (factorn), and the ratio of shell thickness,R-s, relative to the particle radius,R-p, (factorg) were chosen as main parameters to be iterated. By systematically varying these two factors,nandg, we succeeded in minimizing the fluctuation of apparent diffusion rate constant by the particle size. Despite the oversimplified model and lacking experimental evidences of the hypothetical parameters, the present proposal may pave the way to introduce ROS and its local distribution into the reaction kinetics. We also discussed the effects of second phases by comparing the same reaction process observed from the decomposition of the reactant and formation of the products. ⓘ Cho, Sang-Hee; Senna, Mamoru ⓘ Kyungpook Natl Univ, Daegu 41566, South Korea; Keio Univ, Yokohama, Kanagawa, Japan ⓘ Senna, Mamoru/G-2534-2012 ⓘ 26435119100; 7006132840 ⓘ shcho@knu.ac.kr; ⓘ JOURNAL OF THE AMERICAN CERAMIC SOCIETY ⓘ J AM CERAM SOC ⓘ 0002-7820 1551-2916 103 11 SCIE MATERIALS SCIENCE, CERAMICS ⓘ 2020 3.784 12.1 0.07 2025-06-25 ⓘ 2 2 barium titanate; core-shell structures; diffusion; diffusivity; particle size; reaction rate ⓘ BARIUM-TITANATE; BATIO3 POWDERS; PARTICLES; DIFFUSION; PHASE; BACO3; NANOCRYSTALS; DIELECTRICS; ACTIVATION; CHALLENGES ⓘ barium titanate; core-shell structures; diffusion/diffusivity; particle size; reaction rate ⓘ Addition reactions; Association reactions; Barium titanate; Diffusion; Geographical distribution; Integral equations; Kinetic energy; Kinetic theory; Kinetics; Oxide minerals; Particle size; Rate constants; Shells (structures); Solid state reactions; Titanium dioxide; Defect concentrations; Diffusion controlled; Diffusion rate constants; Experimental evidence; Near surface regions; Rate determining step; Solid-state addition reaction; Solid-state reaction process; Equations of state of solids ⓘ English 2020 2020-11 10.1111/jace.17372 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Adsorption of Ba²⁺ and Sr²⁺ on Ti3C2Tx MXene in model fracking wastewater ⓘ Wastewater from hydraulic fracking contains both organic and inorganic pollutants; the latter include radioactive nuclides such as Ba2+ and Sr2+. We explored whether MXene (Ti3C2Tx), a novel adsorbent, could remove Ba2+ and Sr2+ from model wastewater. Zeta potential analysis showed that MXene had a high negative surface charge. MXene adsorbed Ba2+ and Sr2+ via electrostatic attraction, as confirmed by the adsorption at different solution pH values and in the presence of various concentrations of other ions (NaCl and CaCl2). MXene exhibited outstanding adsorption of Ba2+ and Sr2+, to approximately 180 and 225 mg g(-1), respectively, when 1 g L-1 MXene was admixed with adsorbates at 2 g L-1. MXene exhibited very rapid adsorption kinetics, attaining equilibrium within 1 h. X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy revealed that MXene adsorbed Ba2+ and Sr2+, respectively, via ion exchange and inner-sphere complex formation. Finally, we performed MXene reusability tests; reusability was excellent over at least four cycles. Thus, MXene removed Ba2+ and Sr2+ from model fracking wastewater. ⓘ Jun, Byung-Moon; Park, Chang Min; Heo, Jiyong; Yoon, Yeomin ⓘ Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Army Acad Young Cheon, Dept Civil & Environm Engn, 495 Hogook Ro, Young Cheon 38900, Gyeongbuk, South Korea ⓘ Jun, Byung-Moon/Y-2134-2019; Park, Chang Min/CAA-8506-2022; Yoon, Yeomin/KDP-2253-2024 ⓘ 55326699900; 57209588953; 42461338400; 7402126688 ⓘ jiyongheo@naver.com;yoony@cec.sc.edu; ⓘ JOURNAL OF ENVIRONMENTAL MANAGEMENT ⓘ J ENVIRON MANAGE ⓘ 0301-4797 1095-8630 256 SCIE ENVIRONMENTAL SCIENCES ⓘ 2020 6.789 12.2 4.2 2025-06-25 ⓘ 119 135 Ba2+/Sr2+; Mechanism; Adsorption; MXene; Frocking wastewater ⓘ METAL-ORGANIC FRAMEWORK; AQUEOUS-SOLUTION; TITANIUM CARBIDE; REMOVAL; EFFICIENT; STRONTIUM; DYE; MEMBRANE; SURFACE; BLUE ⓘ Adsorption; Ba<sup>2+</sup>/Sr<sup>2+</sup>; Fracking wastewater; Mechanism; MXene ⓘ Adsorption; Hydraulic Fracking; Kinetics; Titanium; Waste Water; Water Pollutants, Chemical; Fourier transform infrared spectroscopy; Ion exchange; Reusability; Sodium chloride; X ray photoelectron spectroscopy; titanium; Ba2+/sr2+; Electrostatic attractions; Fracking wastewater; Inorganic pollutants; Mxene; Negative surface charges; Organics; pH value; Solution pH; Zeta potential analysis; adsorption; fracking; kinetics; waste water; water pollutant; Adsorption ⓘ English 2020 2020-02-15 10.1016/j.jenvman.2019.109940 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Boosted insights of novel accordion-like (2D/2D) hybrid photocatalyst for the removal of cationic dyes: Mechanistic and degradation pathways ⓘ In the present work, a novel (2D/2D) accordion like CS@g-C3N4/MX hybrid composite was prepared through one-pot hydro-thermal synthesis method and utilized as a catalyst for the degradation of organic persistent dyes such as methylene blue (MB) and rhodamine B (RhB). Because the removal of such organic compounds is a major dispute in environmental aspects. In this study, the bio-assisted g-C3N4/MX nanosheets was utilized for the removal of organic dyes from aqueous solution under visible light irradiation, respectively. The CS@g-C3N4/MX photocatalyst showed high catalytic activity based on-99% and-98.5% degradation of MB and RhB within 60 and 40 min using visible light irradiation. This outcome could have resulted in greater catalytic enactment towards the degradation of other persistent pollutants with enhanced light absorption property and it can efficiently suppress photo-generated charge recombination, thus improving the interfacial charge transfer rate. The (OH)-O-center dot radical was being effective oxidative species involved in the CS@g-C3N4/MX system for the degradation of organic contaminants. Furthermore, CS@g-C3N4/MX showed excellent photo-stability over five consecutive cycles for the degradation of organic dyes with negligible loss of photocatalytic activity. Finally, the purposed catalytic mechanisms and degradation pathways of MB and RhB were systematically discussed in detail based on experimental results. Thus, the organics which oxidized into ring-opened compounds such as ethoxyethane, butadiene etc., to non-toxic products like H2O, CO2 and some mineral salts . ⓘ Vigneshwaran, Sivakumar; Karthikeyan, Perumal; Park, Chang Min; Meenakshi, Sankaran ⓘ Gandhigram Rural Inst Deemed Be Univ, Dept Chem, Dindigul 624302, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea ⓘ Park, Chang Min/CAA-8506-2022; Meenakshi, Sankaran/AAF-5748-2020; Vigneshwaran, Sivakumar/AAE-6278-2022; Karthikeyan, Perumal/T-6719-2019; Vigneshwaran, Siva kumar/IST-9536-2023 ⓘ ⓘ vigneshwarangri@gmail.com;karthi2011chemistry@gmail.com;cmpark@knu.ac.kr;sankaranmeenakshi2014@gmail.com; ⓘ JOURNAL OF ENVIRONMENTAL MANAGEMENT ⓘ J ENVIRON MANAGE ⓘ 0301-4797 1095-8630 273 SCIE ENVIRONMENTAL SCIENCES ⓘ 2020 6.789 12.2 ⓘ 51 2D/2D hybrid photocatalyst; MXene; Cationic-dyes; Photo-degradation; Oxidative pathway ⓘ VISIBLE-LIGHT; RHODAMINE-B; ADVANCED OXIDATION; GRAPHENE OXIDE; TI3C2 MXENE; WATER; NANOCOMPOSITES; ADSORPTION; COMPOSITE; PHOTODEGRADATION ⓘ ⓘ ⓘ English 2020 2020-11-01 10.1016/j.jenvaman.2020.11125 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Computation of Molecular Ionization Energies Using an Ensemble Density Functional Theory Method ⓘ Computation of the ionization energies and of the respective Dyson orbitals based on the use of the extended Koopmans theorem (EKT) is implemented in connection with an ensemble density functional theory (eDFT) method, the state-interaction state-averaged spin-restricted ensemble-referenced Kohn-Sham (SI-SA-REKS or SSR) method. The new methodology enables fast computation of the ionization energies and evaluation of the respective Dyson orbitals, the square norms of which are related with the ionization probabilities, in the ground and excited electronic states of molecules. As the application of EKT recycles the intermediate quantities from the SSR analytical energy gradient, evaluation of the ionization energies and probabilities can be carried out on-the-fly during the nonadiabatic molecular dynamics simulations. This opens up a perspective for fast theoretical simulation of the time-resolved photoelectron spectroscopy observations. In the present work, the new methodology is tested in the computation of the ionization energies and Dyson orbitals of several molecules in the ground and excited electronic states, including strongly correlated species, such as the ozone molecule, dissociating chemical bonds, and conical intersections. ⓘ Filatov, Michael; Lee, Seunghoon; Choi, Cheol Ho ⓘ CALTECH, Div Chem & Chem Engn, Pasadena, CA 91125 USA; Kyungpook Natl Univ, Dept Chem, Daegu 702701, South Korea ⓘ Lee, Seunghoon/AAB-4846-2021; Choi, Cheol Ho/AAA-4705-2020 ⓘ 7005134246; 57194591254; 7402958948; 57940570600 ⓘ mike.filatov@gmail.com;cheolho.choi@gmail.com; ⓘ JOURNAL OF CHEMICAL THEORY AND COMPUTATION ⓘ J CHEM THEORY COMPUT ⓘ 1549-9618 1549-9626 16 7 SCIE CHEMISTRY, PHYSICAL;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL ⓘ 2020 6.006 12.2 0.59 2025-06-25 ⓘ 10 10 ⓘ REFERENCED KOHN-SHAM; RESOLVED PHOTOELECTRON-SPECTROSCOPY; FRACTIONALLY OCCUPIED STATES; ELECTRON PROPAGATOR THEORY; LONG-RANGE BEHAVIOR; EXCITATION-ENERGIES; EXCITED-STATES; HARTREE-FOCK; MOUNTAINEERING STRATEGY; KOOPMANS THEOREM ⓘ ⓘ ⓘ English 2020 2020-07-14 10.1021/acs.jctc.0c00218 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Pharmacologic properties of high-dose ambroxol in four patients with Gaucher disease and myoclonic epilepsy ⓘ Background Ambroxol (ABX) has been suggested as an augmentative pharmacological agent for neuronopathic Gaucher disease (nGD). This study assessed the long-term safety and efficacy of combined therapy with high-dose ABX and enzyme replacement therapy (ERT) in nGD. Methods ABX+ERT therapy was administered for 4.5 years in four patients with nGD. ABX was initiated at a dose of 1.5 mg/kg/day, and the dose was escalated up to 27 mg/kg/day. The target plasma level was 10 mu mol/L or less. The changes in glucocerebrosidase activity, biochemical, safety and neurocognitive findings were assessed. Results Enhanced residual GCcase activity was observed in all patients, as evidenced in both in vitro and in vivo studies. During the first 2 years of study with ABX (up to 21 mg/kg/day), mean seizure frequencies and neurocognitive function worsened. After ABX dosage was increased up to 27 mg/kg/day of ABX, its trough plasma concentration was 3.2-8.8 mu mol/L. Drug-to-drug interaction, especially with antiepileptic drug significantly affected the pharmacokinetic parameters of ABX. Importantly, at 27 mg/kg/day of ABX, the seizure frequencies markedly decreased from the baseline, and the neurocognitive function was improved. In addition, Lyso-Gb1, a biomarker for the severity and progression of GD, was normalised in all patients. High-dose ABX was well-tolerated with no severe adverse events. Conclusions Long-term treatment with high-dose ABX+ERT was safe and might help to arrest the progression of the neurological manifestations in GD. ⓘ Kim, Yoon-Myung; Yum, Mi-Sun; Heo, Sun Hee; Kim, Taeho; Jin, Hee Kyung; Bae, Jae-sung; Seo, Go Hun; Oh, Arum; Yoon, Hee Mang; Lim, Hyun Taek; Kim, Hyo-Won; Ko, Tae-Sung; Lim, Hyeong-Seok; Osborn, Mark J.; Tolar, Jakub; Cozma, Claudia; Rolfs, Arndt; Zimran, Ari; Lee, Beom Hee; Yoo, Han-Wook ⓘ Gangneung Asan Hosp, Dept Pediat, Kangnung, South Korea; Univ Ulsan, Coll Med, Dept Pediat, Asan Med Ctr,Childrens Hosp, Seoul, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Asan Inst Life Sci, Seoul, South Korea; Kyungpook Natl Univ, Dept Lab Anim Med, Coll Vet Med, Daegu, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Sch Med, Dept Physiol, Daegu, South Korea; Univ Ulsan, Coll Med, Dept Radiol, Seoul, South Korea; Univ Ulsan, Coll Med, Res Inst Radiol, Asan Med Ctr, Seoul, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Ophthalmol, Seoul, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Psychiat, Seoul, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Clin Pharmacol & Therapeut, Seoul, South Korea; Univ Minnesota, Dept Pediat, Med Ctr, Div Blood & Marrow Transplantat, Minneapolis, MN 55455 USA; Centogene AG, Rostock, Germany; Med Univ Rostock, Albrecht Kossel Inst Neuroregenerat, Rostock, Germany; Hebrew Univ Jerusalem, Hadassah Med Sch, Jerusalem, Israel; Univ Ulsan, Coll Med, Asan Med Ctr, Med Genet Ctr, Seoul, South Korea ⓘ Bae, Jae-sung/AAM-8663-2021; Kim, Young/T-8521-2019; Lim, Hyeong-seok/AAX-4732-2020; Kim, Hyo-Won/M-9932-2019 ⓘ 57190732748; 21735652500; 57202484161; 59442794700; 8088145800; 35209510400; 57062033100; 57210467812; 49664266000; 8441595200; 13402798900; 7201681358; 7403095362; 8696421900; 8696421700; 35078299100; 7006605320; 7006390817; 55513175800; 7201373304 ⓘ bhlee@amc.seoul.kr;hwyoo@amc.seoul.kr; ⓘ JOURNAL OF MEDICAL GENETICS ⓘ J MED GENET ⓘ 0022-2593 1468-6244 57 2 SCIE GENETICS & HEREDITY ⓘ 2020 6.318 12.2 1.99 2025-06-25 ⓘ 40 40 ⓘ GLUCOCEREBROSIDASE GENE; TYPE-3; CHAPERONE; THERAPY; PLASMA; GLUCOSYLSPHINGOSINE; IDENTIFICATION; CHILDREN; STORAGE ⓘ Metabolic disorders; Neurology; Parkinson's disease ⓘ Adolescent; Ambroxol; Biomarkers; Child; Dose-Response Relationship, Drug; Enzyme Replacement Therapy; Epilepsies, Myoclonic; Female; Gaucher Disease; Glucosylceramidase; Humans; Male; acetylcysteine; ambroxol; anticonvulsive agent; glucosylceramidase; ambroxol; biological marker; glucosylceramidase; adolescent; adult; Article; bone densitometry; case report; clinical article; clinical outcome; disease severity; disorders of higher cerebral function; drug blood level; drug dose escalation; drug efficacy; drug megadose; drug safety; drug tolerability; enzyme activity; enzyme replacement; extrapyramidal symptom; female; Gaucher disease; human; in vitro study; in vivo study; long term care; mucus secretion; myoclonus epilepsy; myoclonus seizure; onset age; priority journal; proteinuria; pyramidal sign; respiratory tract disease; saccadic eye movement; treatment duration; tremor; trough concentration; young adult; blood; child; dose response; enzyme replacement; Gaucher disease; male; myoclonus epilepsy; pathology ⓘ English 2020 2020-02 10.1136/jmedgenet-2019-106132 ⓘ 바로가기 바로가기 바로가기 바로가기

The main idea of our method is to transform the given PDE into the relatively simple ordinary differential equations(ODE) using double Mellin transforms. By using inverse double Mellin transforms, we derive the analytic representation of the solutions for the (1+2)-dimensional Black-Scholes equation with a mixed boundary condition. Moreover, we apply our method to European maximum-quanto lookback options and derive the pricing formula of this options. ⓘ Jeon, Junkee; Oh, Jehan ⓘ Kyung Hee Univ, Dept Appl Math, Yongin 17104, South Korea; Kyung Hee Univ, Inst Nat Sci, Yongin 17104, South Korea; Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea ⓘ ⓘ 57056929900; 56673305300 ⓘ junkeejeon@khu.ac.kr;jehan.oh@knu.ac.kr; ⓘ COMMUNICATIONS ON PURE AND APPLIED ANALYSIS ⓘ COMMUN PUR APPL ANAL ⓘ 1534-0392 1553-5258 19 2 SCIE MATHEMATICS, APPLIED;MATHEMATICS ⓘ 2020 1.916 12.3 0 2025-06-25 ⓘ 0 0 (1+2)-dimensional Black-Scholes equations; parabolic partial differential equations; double-Mellin transform; mixed boundary condition; option pricing ⓘ OPTIONS ⓘ (1+2)-dimensional Black-Scholes equations; Double-Mellin transform; Mixed boundary condition; Option pricing; Parabolic partial differential equations ⓘ ⓘ English 2020 2020-02 10.3934/cpaa.2020032 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Activated pathogenic Th17 lymphocytes induce hypertension following high-fructose intake in Dahl salt-sensitive but not Dahl salt-resistant rats ⓘ High-salt intake and high-fructose intake are risk factors for hypertension via oxidative stress and inflammation. T helper (Th)17 lymphocytes play an important role in the development of hypertension. Here, we tested the hypothesis that activation of pathogenic Th17 lymphocytes induces hypertension after high-fructose intake in Dahl salt-sensitive (SS) but not Dahl salt-resistant (SR) rats. Eight-week-old male SS and SR rats were offered 20% fructose solution or tap water only for 4 weeks. Systolic blood pressure was measured by the tail-cuff method. T lymphocyte [Th17 and T regulatory (Treg)] profiling was determined via flow cytometry. The expression of Th17-related (IL-17A, IL-17RA, IL-23R and ROR gamma t) and Treg-related (IL-10. CD25, FOXP3 and TGF beta) factors were measured via ELISA or qRT-PCR. Th17 lymphocytes isolated from high-fructose-fed SS rats were intraperitoneally injected into recipient SS and SR rats, and recombinant IL-23 protein was subcutaneously injected into SS and SR rats to induce hypertension. High-fructose intake induced hypertension via the activation of pathogenic Th17 lymphocytes in SS but not SR rats. Injection of activated Th17 lymphocytes isolated from fructose-fed SS rats induced hypertension via increase of serum IL-17A only in recipient SS rats. In addition, injection of IL-23 induced hypertension via activation of pathogenic Th17 lymphocytes only in SS rats. Thus, activation of pathogenic Th17 lymphocytes induces hypertension after high-fructose intake in SS but not SR rats. These results indicate that immunologic tolerance plays an important role in protection against hypertension in SR rats. ⓘ Lee, Eunjo; Kim, Namkyung; Kang, Jinjoo; Yoon, Sangwon; Lee, Hae-Ahm; Jung, Hanna; Kim, Sang-Hyun; Kim, Inkyeom ⓘ Kyungpook Natl Univ, Sch Med, Dept Pharmacol, Daegu 41944, South Korea; Kyungpook Natl Univ, Cardiovasc Res Inst, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, BK21 Plus KNU Biomed Convergence Program, Daegu 41944, South Korea; Kyung Hee Univ, Med Res Ctr Bioreact React Oxygen Species, Sch Med, Grad Sch, Seoul 02447, South Korea; Kyung Hee Univ, Sch Med, Biomed Sci Inst, Grad Sch, Seoul 02447, South Korea; Kyungpook Natl Univ Hosp, Dept Thorac & Cardiovasc Surg, Daegu 41944, South Korea ⓘ ; Jung, Hanna/Y-4165-2019 ⓘ 57190980166; 57216981866; 57216977823; 57216499531; 8286155900; 56467570700; 57210450420; 7404144630 ⓘ inkim@knu.ac.kr; ⓘ DISEASE MODELS & MECHANISMS ⓘ DIS MODEL MECH ⓘ 1754-8403 1754-8411 13 5 SCIE CELL BIOLOGY;PATHOLOGY ⓘ 2020 5.758 12.3 2.14 2025-06-25 ⓘ 23 24 Th17 lymphocytes; Treg lymphocytes; Fructose; Hypertension; Dahl salt sensitive rat; Dahl salt-resistant rat ⓘ SODIUM-CHLORIDE; INSULIN-RESISTANCE; BLOOD-PRESSURE; DIFFERENTIATION; INFILTRATION; INHIBITOR; MUTATION; DISEASE; CELLS; SGK1 ⓘ Dahl salt-resistant rat; Dahl salt-sensitive rat; Fructose; Hypertension; Th17 lymphocytes; Treg lymphocytes ⓘ Animals; Blood Pressure; Body Weight; Cytokines; Forkhead Transcription Factors; Fructose; Glucose Intolerance; Hypertension; Immediate-Early Proteins; Interleukin-23; Lymphocyte Activation; Male; Models, Biological; Phosphorylation; Protein-Serine-Threonine Kinases; Rats, Inbred Dahl; Signal Transduction; Systole; T-Lymphocytes, Regulatory; Th17 Cells; fructose; interleukin 10; interleukin 17; interleukin 17 receptor; interleukin 2 receptor alpha; interleukin 23 receptor; retinoic acid receptor gamma; strontium; tap water; transcription factor FOXP3; transforming growth factor beta; cytokine; forkhead transcription factor; immediate early protein; interleukin 23; protein serine threonine kinase; serum-glucocorticoid regulated kinase; animal experiment; animal model; Article; blood pressure measurement; controlled study; Dahl salt resistant rat; Dahl salt sensitive rat; enzyme linked immunosorbent assay; flow cytometry; fructose intake; hypertension; immunological tolerance; lymphocyte activation; male; nonhuman; priority journal; protein expression; protein phosphorylation; rat; real time reverse transcription polymerase chain reaction; regulatory T lymphocyte; systolic blood pressure; Th17 cell; Western blotting; animal; biological model; blood; blood pressure; body weight; complication; Dahl rat; glucose intolerance; hypertension; immunology; metabolism; phosphorylation; regulatory T lymphocyte; signal transduction; systole; Th17 cell ⓘ English 2020 2020-05 10.1242/dmm.044107 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Prediction of motor recovery using indirect connectivity in a lesion network after ischemic stroke ⓘ Background: Recovery prediction can assist in the planning for impairment-focused rehabilitation after a stroke. This study investigated a new prediction model based on a lesion network analysis. To predict the potential for recovery, we focused on the next link-step connectivity of the direct neighbors of a lesion. Methods: We hypothesized that this connectivity would contribute to recovery after stroke onset. Each lesion in a patient who had suffered a stroke was transferred to a healthy subject. First link-step connectivity was identified by observing voxels functionally connected to each lesion. Next (second) link-step connectivity of the first link-step connectivity was extracted by calculating statistical dependencies between time courses of regions not directly connected to a lesion and regions identified as first link-step connectivity. Lesion impact on second link-step connectivity was quantified by comparing the lesion network and reference network. Results: The lower the impact of a lesion was on second link-step connectivity in the brain network, the better the improvement in motor function during recovery. A prediction model containing a proposed predictor, initial motor function, age, and lesion volume was established. A multivariate analysis revealed that this model accurately predicted recovery at 3 months poststroke (R (2)& x2004;=& x2004;0.788; cross-validation, R (2)& x2004;=& x2004;0.746, RMSE & x2004;=& x2004;13.15). Conclusion: This model can potentially be used in clinical practice to develop individually tailored rehabilitation programs for patients suffering from motor impairments after stroke. ⓘ Lee, Jungsoo; Park, Eunhee; Lee, Ahee; Chang, Won Hyuk; Kim, Dae-Shik; Kim, Yun-Hee ⓘ Sungkyunkwan Univ, Dept Phys & Rehabil Med, Sch Med,Dept Hlth Sci & Technol,SAIHST,Ctr Preven, Dept Digital Hlth,Heart Vasc Stroke Inst,Samsung, 81 Irwon Ro, Seoul 06351, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Dept Phys & Rehabil Med, Sch Med, Seoul, South Korea; Kyungpook Natl Univ, Med Ctr, Dept Phys & Rehabil Med, Daegu, South Korea; Sungkyunkwan Univ, Dept Hlth Sci & Technol, Dept Med Device Management & Res, Dept Digital Hlth,SAIHST, Seoul, South Korea; Korea Adv Inst Sci & Technol, Sch Elect Engn, Daejeon, South Korea ⓘ Kim, Yun-Hee/GVS-6426-2022; Ronen, Itamar/E-8518-2016 ⓘ 55325969400; 56107216400; 56113572400; 35301717900; 26637469800; 57020121600 ⓘ yunkim@skku.edu;yun1225.kim@samsung.com; ⓘ THERAPEUTIC ADVANCES IN NEUROLOGICAL DISORDERS ⓘ THER ADV NEUROL DISO ⓘ 1756-2856 1756-2864 13 SCIE CLINICAL NEUROLOGY ⓘ 2020 6.57 12.3 0.25 2025-06-25 ⓘ 4 4 lesion network; motor function; motor recovery; prediction model; stroke ⓘ FUNCTIONAL REORGANIZATION; VOLUME; BRAIN; LOCALIZATION; OUTCOMES; SIGNAL; AGE ⓘ lesion network; motor function; motor recovery; prediction model; stroke ⓘ adult; age; analytical parameters; Article; brain damage; cerebrovascular accident; clinical practice; female; functional connectivity; functional magnetic resonance imaging; human; image segmentation; indirect connectivity; lesion network analysis; lesion volume; major clinical study; male; middle aged; motor dysfunction; motor performance; motor recovery; nerve cell network; nuclear magnetic resonance imaging; prediction; priority journal ⓘ English 2020 2020-05 10.1177/1756286420925679 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Zmo0994, a novel LEA-like protein fromZymomonas mobilis, increases multi-abiotic stress tolerance inEscherichia coli ⓘ Background Pretreatment processes and subsequent enzymatic hydrolysis are prerequisites to utilize lignocellulosic sugar for fermentation. However, the resulting hydrolysate frequently hinders fermentation processes due to the presence of inhibitors and toxic products (e.g., ethanol). Thus, it is crucial to develop robust microbes conferring multi-stress tolerance. Results Zmo0994, a functionally uncharacterized protein fromZymomonas mobilis, was identified and characterized for the first time. A major effect of Zmo0994 was a significant enhancement in the tolerance to abiotic stresses such as ethanol, furfural, 5 '-hydroxymethylfurfural and high temperature, when expressed inEscherichia coli. Through transcriptome analysis and in vivo experiments, the cellular mechanism of this protein was revealed as due to its ability to trigger genes, involved in aerobic respiration for ATP synthesis. Conclusions These findings have significant implications that might lead to the development of robust microbes for the highly efficient industrial fermentation processes. ⓘ Yang, Jungwoo; Kim, Ha Eun; Jung, Young Hoon; Kim, Jungyeon; Kim, Do Hyoung; Walmsley, Adrian R.; Kim, Kyoung Heon ⓘ Korea Univ, Grad Sch, Dept Biotechnol, Seoul 02841, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, 80 Daehak Ro, Daegu 41566, South Korea; Univ Durham, Dept Biosci, South Rd, Durham DH1 3LE, England ⓘ ; Kim, Jinkwon/AAR-6729-2021; kim, jong-eun/B-3550-2017; Kim, Kyoung/F-1059-2013; Jung, Young/F-1703-2013; Kim, Kyoung Heon/F-1059-2013 ⓘ 58371682700; 57193917212; 55550063700; 57214338692; 56739384900; 7103287691; 34770896300 ⓘ khekim@korea.ac.kr; ⓘ BIOTECHNOLOGY FOR BIOFUELS ⓘ BIOTECHNOL BIOFUELS ⓘ 1754-6834 13 1 SCIE BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS ⓘ 2020 6.04 12.3 0.54 2025-06-25 ⓘ 9 10 Abiotic stress; Inhibitors; Multi-stress tolerance; Zmo0994; Zymomonas mobilis ⓘ DNA-BINDING PROTEIN; HEAT-SHOCK RESPONSE; ESCHERICHIA-COLI; OXIDATIVE STRESS; ETHANOL TOLERANCE; ZYMOMONAS-MOBILIS; GENOME SEQUENCE; STARVED CELLS; HSP 12; GENE ⓘ Abiotic stress; Inhibitors; Multi-stress tolerance; Zmo0994; Zymomonas mobilis ⓘ Escherichia coli; Zymomonas mobilis; Enzymatic hydrolysis; Escherichia coli; Ethanol; Fermentation; Process control; Abiotic stress tolerances; Aerobic respiration; Fermentation process; Hydroxymethylfurfural; In-vivo experiments; Industrial fermentation; Pretreatment process; Transcriptome analysis; abiotic factor; biofuel; coliform bacterium; fermentation; inhibitor; oxidative stress; protein; Biosynthesis ⓘ English 2020 2020-08-26 10.1186/s13068-020-01790-0 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Facile fabrication of mesoporous carbon from mixed polymer precursor of PVDF and PTFE for high-power supercapacitors ⓘ Highly porous activated carbon is an essential electrode material for high-energy-density super-capacitors, since the electrical charge is stored through electrolyte-ion adsorption on an electrode with high surface area. Here, we report the facile and simple synthesis of an activated carbon with tailored porosity from the blended polymers with different thermal stabilities, i.e., polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE). Through a thermal treatment (900 degrees C) under inert atmosphere, PVDF is simply transformed into highly microporous (<2 nm) carbon, owing to the release of the combined hydrogen and fluoride. The microporous surface morphology reduces the specific capacitance at high discharging rates. Meanwhile, the PTFE is completely evaporated to the C2F4 gas at 900 degrees C under an inert environment. The mixed polymer with a specific ratio (PVDF:PTFE = 2:1) is carbonized to porous carbon with a highly accessible surface area. The mesopore (2-50 nm) formed via C2F4-gas escape from PTFE facilitates ionic transfer to the surface at a rapid discharging rate with the high specific capacitance, i.e., 99 F g(-1). Compared with the PVDF-alone derived carbon, the carbon derived from the appropriately mixed precursors exhibits a 19 % higher specific capacitance and increased capacity retention at a 10-fold faster discharging rate.
