| 1 | Effects of extremely low frequency magnetic fields on gap junctional intercellular communication and its mechanism显示文摘The study on biological effect of electromagnetic fields has been paid close attention in recent years. Gap junctional intercellular communication (GJIC) plays an important role in the maintenance of cell proliferation and differentiation, and in the multistage process of carcinogenesis. A series of researches showed that xtremely low frequency (ELF) magnetic fields not only enhance the inhibition of GJIC induced by 12-O-tetradecanoylphorbol-13-acetate, but also inhibit GJIC directly when the intensity is equal to or more than 0.4 mT, and that the mechanisms of GJIC inhibition by ELF magnetic fields are due to hyperphosphorylation of connexin 43, which is mediated by protein kinase C-activated signal transduction, and the internalization of connexin 43 from plasma membrane to cytoplasm. | CHIANG Huai , HU Genlin and XU Zhengping(Microwave Laboratory, Zhejiang University School of Medicine, Hangzhou 310031, China) | 2002 | Progress in Natural Science:Materials International2002，12，3： | 2 |
| 2 | Cloning and identification of magnetic field-responsive genes in Daudi cells显示文摘In order to study the molecular mechanisms of ELF MF biological effects, the differential display (DD) technology has been used to isolate differentially expressed cDNA fragments in Daudi cells after 50 Hz MF exposure and sham-exposure. Using total RNA isolated from 0.8 ml 50 Hz MF exposed cells and those from sham-exposed cells, one differentially regulated transcript has been found by DD and the expression pattern of the same transcript has been verified by reverse-Northern and Northern analyses. DNA sequence analysis and Genbank research demonstrated that the cDNA fragment (MF-CA) is a novel gene in human cell which is induced by ELF MF. | Ruiying Wu Huai Jiang Genlin Hu Yiti Fu Deqiang Lu | 2000 | Chinese Science Bulletin2000，45，11： | 1 |
| 3 | Boosting the Rate Performance of Li–S Batteries via Highly Dispersed Cobalt Nanoparticles Embedded into Nitrogen-Doped Hierarchical Porous Carbon显示文摘Lithium–sulfur(Li–S)batteries are one of the most promising alternatives to lithium–ion batteries because of the advantageous high energy density and low cost.However,the practical applications of Li–S batteries are hampered by a severe shuttle effect and sluggish polysulfide redox conversion.Herein,highly dispersed cobalt nanoparticles(∼0.8 wt%)embedded into nitrogen-doped hierarchical porous carbon(Co@N-HPC)are designed as an effective electrocatalyst for Li–S batteries,which exhibit a synergistic effect of anchoring and dual-directional catalytic conversion of polysulfides. | Cheng Yuan Pan Zeng Chen Cheng Tianran Yan Genlin Liu Wenmin Wang Jun Hu Xin Li Junfa Zhu Liang Zhang | 2022 | CCS Chemistry2022，4，8： | 1 |
