1Origin and evolution of ore-forming fluid for the Gaosongshan gold deposit, Lesser Xing’an Range:Evidence from fluid inclusions,H-O-S-Pb isotopes显示文摘Epithermal gold deposits are typical precious metal deposits related to volcanic and subvolcanic magmatism.Due to the lack of direct geological and petrographic evidences,the origin of the ore-forming fluid is deduced from the spatial diagenesis-mineralization relationship,chronological data,physicochemical characteristics of mineral fluid inclusions,mineral or rock elements and isotopic geochemical characteristics.By objectively examining this scientific problem via a geological field survey and petrographic analysis of the Gaosongshan epithermal gold deposit,we recently discovered and verified the following points:(1) Pyrite-bearing spherical quartz aggregates (PSQA) occur in the rhyolitic porphyry;(2) the mineralization is structurally dominated by WNW- and ENE-trending systems and occurs mostly in hydrothermal breccias and pyrite-quartz veins,and the ore types are mainly hematite-crusted quartz,hydrothermal breccia,massive pyrite-quartz,etc.;(3) the alteration types consist of prevalent silicification,sericitization,propylitization and carbonation,with local adularization and illitization.The ore minerals are mainly pyrite,primary hematite,native gold,and electrum,with lesser amounts of chalcopyrite,magnetite,sphalerite,and galena,indicating a characteristic epithermal low-sulfidation deposit.The ore-forming fluid may have been primarily derived from magmatic fluid exsolved from a crystallizing rhyolitic porphyry magma.Further zircon U-Pb geochronology,fluid inclusion,physicochemical and isotopic geochemical analyses revealed that (1) rhyolitic porphyry magmatism occurred at 104.6 ± 1.0 Ma,whereas the crystallization of the PSQA occurred at 100.8 ± 2.1 Ma;(2) the hydrothermal fluid of the pre-ore stage was an exsolved CO2-bearing H2O-NaCl magmatic fluid that produced inclusions mainly composed of pure vapor (PV),vapor-rich (WV) and liquid-rich (WL) inclusions with a small number of melt-(M) and solid-bearing (S) inclusions;mineralization-stage quartz contains WL and rare PV,WV and pure liquid (PL) inclusions characterized by the H2O-NaCl system with low formation temperatures and low salinities;(3) the characteristics of hydrogen,oxygen,sulfur,and lead isotopes and those of rare earth elements (REEs) provide insight into the affinity between PSQA and orebodies resulting from juvenile crust or enriched mantle.Combined with previous research on the mineralogenetic epoch (99.32 ± 0.01 Ma),we further confirm that the mineralization of the deposit occurred in the late Early Cretaceous,which coincides with the extension of the continental margin induced by subduction of the Pacific Plate beneath the Eurasian Plate.The formation of the ore deposit was proceeded by a series of magmatic and hydrothermal events,including melting of enriched juvenile crust,upwelling,the eruption and emplacement of the rhyolitic magma,the exsolution and accumulation of magmatic hydrothermal fluid,decompression,the cooling and immiscibility/boiling of the fluid,and mixing of the magmatic fluid with meteoric water,in association with water-rock interaction.Yang Liu Jinggui Sun Jilong Han Liang Ren Alei Gu Keqiang Zhao Changshen Wang 2019Geoscience Frontiers2019,10,5:3
2Hypoxia induces T-cell apoptosis by inhibiting chemokine C receptor 7 expression:the role of adenosine receptor A2显示文摘Hypoxia is a major characteristic of the tumor microenvironment,and its effects on immune cells are proposed to be important factors for the process of tumor immune escape.It has been reported that hypoxia affects the function of dendritic cells and the antitumor function of T cells.Here we discuss the effects of hypoxia on T-cell survival.Our results showed that hypoxia induced apoptosis of T cells.Adenosine and adenosine receptors(AR)are important to the hypoxia-related signaling pathway.Using AR agonists and antagonists,we demonstrated that hypoxia-induced apoptosis of T cells was mediated by A^(2a)and A^(2b)receptors.Furthermore,we are the first,to our knowledge,to report that hypoxia significantly inhibited the expression of chemokine C receptor 7(CCR7)of T cells via the A^(2)R signal pathway,perhaps representing a mechanism of hypoxia-induced apoptosis of T cells.Collectively,our research demonstrated that hypoxia induces T-cell apoptosis by the A^(2)R signaling pathway partly by suppressing CCR7.Blocking the A^(2)R signaling pathway and/or activation of CCR7 can increase the anti-apoptosis function of T cells and may become a new strategy to improve antitumor potential.Jintang Sun Yan Zhang Meixiang Yang Yun Zhang Qi Xie Zewu Li Zhaogang Dong Yongmei Yang Biping Deng Alei Feng Weixu Hu Haiting Mao Xun Qu 2010Cellular & Molecular Immunology2010,7,1:3
3Preparation and electrochemical property of CMC/MWCNT composite using ionic liquid as solvent显示文摘Carboxymethyl cellulose sodium(CMC)/multi-walled carbon nanotube(MWCNT) composite was prepared by dissolving CMC with ionic liquid as solvent.The microstructure and electrochemical properties of CMC/MWCNTs were studied using field emission scanning electron microscopy(FE-SEM),high-resolution transmission electron microscopy(HR-TEM),X-ray diffraction(XRD) system and electrochemical workstation.The experimental results indicated that the CMC dissolved with ionic liquid could be uniformly enwrapped on the surface of MWCNTs,and the coating thickness of CMC was about 5.4 nm.There are obvious oxidation peaks in the cyclic voltammograms curves of glassy carbon electrode coated with a CMC/MWCNT composite in H2O2 phosphate buffer solution.The MWCNT content and ultrasonic time strongly affected the dispersivity and electrochemical property of CMC/MWCNT composite.While the MWCNT content and ultrasonic processing time was 2 wt% and 2 h respectively,CMC/MWCNT composite exhibited excellent electrocatalytic activity.ZHAO TingKai LIU LeHao LI GuangMing DU Li ZHAO Xing YAN Jin CHENG YouLiang DANG ALei LI TieHu 2012Chinese Science Bulletin2012,57,14:3

5Combination of ARTP mutagenesis and color-mediated highthroughput screening to enhance 1-naphthol yield from microbial oxidation of naphthalene in aqueous system显示文摘Strain QCG of the aerobic bacteria Bacillus cereus is capable of producing l-naphthol from naphtha-lene,this strain was first isolated and characterized in this study.Strain QCG was mutagenized to enhance l-naphthol production,using atmospheric and room temperature plasma(ARTP)technology.Then,a microbial clone screening system was used to accelerate the operation.Meanwhile,a novel color-mediated high-throughput screening using 4-aminoantipyrine was performed to screen mutants.The optimal mutant strain QCG4 produced 19.58土0.34 mg·L-1-naphthol from naphthalene that was 47.32%higher than that of the original strain(13.29+0.28 mg·L-1).In addition,the optimal conditions for l-naphthol production via whole-cell catalysis of strain QCG4 were determined to be an OD600 of40,150 mg.L I naphthalene,and 7.5%dimethyl formamide as a co-solvent at pH 7.5 and 26℃ for 3 h,resulting in 41.18士0.12 mg·L-l-naphthol,i.e.,the mutant strain produces a 2.1-fold higher yield compared to the original strain.Chenggang Qiu Alei Zhang Sha Tao Kang Li Kequan Chen Pingkai Ouyang 2020Frontiers of Chemical Science and Engineering2020,14,5:2
