        In Situ Growth of FeCo-selenide on Ni Foam as High-Performance Electrode for Electrochemical Energy Storage Devices

        An Ye,Jiqiu Qi,Yanwei Sui,Fei Yang,Fuxiang Wei,Yezeng He,Qingkun Meng,Zhi Sun 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2018 NANO Vol.13 No.7

        A solid-state energy storage device has been fabricated using FeCo-selenide nanosheet arrays as positive electrode and Fe2O3 nanorod as negative electrode. As an electrode material, the ternary FeCo-selenide nanosheet arrays supported by Ni foam show a highest specific capacitance of 978 F/g (specific capacity of 163 mAh/g) at 1 A/g and a superior cycle behavior of 81.2% are obtained after 5000 cycles at current density of 4 A/g. The asymmetric supercapacitor achieves the maximum energy density of 34.6Wh/kg at the power density of 759.6 W/kg. Furthermore, the superior cycling stability with 83% retention of initial capacitance after 5000 cycles further verify the practical applications of FeCo-selenide//Fe2O3 asymmetric supercapacitor. Meanwhile, the LED bulb and the light board of "CUMT" are lighted by connecting several capacitors to form a series circuit.

        FGFR4 Gly388Arg Polymorphism Affects the Progression of Gastric Cancer by Activating STAT3 Pathway to Induce Epithelial to Mesenchymal Transition

        Yanwei Ye,Jie Li,Dongbao Jiang,Jingjing Li,Chuangfeng Xiao,Yingze Li,Chao Han,Chunlin Zhao 대한암학회 2020 Cancer Research and Treatment Vol.52 No.4

        Purpose Fibroblast growth factor receptor 4 (FGFR4) plays a critical role in cancer progression involving in tumor proliferation, invasion, and metastasis. This study clarified the role of FGFR4-Arg388 variant in gastric cancer (GC), and more importantly highlighted the possibility of this single nucleotide polymorphism (SNP) as potential therapeutic targets. Materials and Methods FGFR4 polymorphism was characterized in advanced GC patients to perform statistical analysis. FGFR4-dependent signal pathways involving cell proliferation, invasion, migration, and resistance to oxaliplatin (OXA) in accordance with the SNP were also assessed in transfected GC cell lines. Results Among 102 GC patients, the FGFR4-Arg388 patients showed significantly higher tumor stage (p=0.047) and worse overall survival (p=0.033) than the Gly388 patients. Immunohistochemical results showed that FGFR4-Arg388 patients were more likely to have higher vimentin (p=0.025) and p-STAT3 (p=0.009) expression compared with FGFR4-Gly388 patients. In transfected GC cells, the overexpression of FGFR4-Arg388 variant increased proliferation and invasion of GC cells, increasing resistance of GC cells to OXA compared with cells overexpressing the Gly388 allele. Conclusion The exploration mechanism may be through FGFR4-Arg388/STAT3/epithelial to mesenchymal transition axis regulating pivotal oncogenic properties of GC cells. The FGFR4-Arg388 variant may be a biomarker and a candidate target for adjuvant treatment of GC.
