1Simultaneous mineralization of CO_2 and recovery of soluble potassium using earth-abundant potassium feldspar显示文摘CO2 capture and storage(CCS) is an important strategy in combatting anthropogenic climate change.However,commercial application of the CCS technique is currently hampered by its high energy expenditure and costs.To overcome this issue,CO2 capture and utilization(CCU) is a promising CO2 disposal method.We,for the first time,developed a promising method to mineralize CO2 using earth-abundant potassium feldspar in order to effectively reduce CO2 emissions.Our experiments demonstrate that,after adding calcium chloride hexahydrate as an additive,the K-feldspar can be transformed to Ca-silicates at 800 C,which can easily mineralize CO2 to form stable calcium carbonate and recover soluble potassium.The conversion of this process reached 84.7%.With further study,the pretreatment temperature can be reduced to 250 C using hydrothermal method by adding the solution of triethanolamine(TEA).The highest conversion can be reached 40.1%.The process of simultaneous mineralization of CO2 and recovery of soluble potassium can be easily implemented in practice and may provide an economically feasible way to tackle global anthropogenic climate change.XIE HePing WANG YuFei JU Yang LIANG Bin ZHU JiaHua ZHANG Ru XIE LingZhi LIU Tao ZHOU XiangGe ZENG HongMei LI Chun LU HouFang 2013Chinese Science Bulletin2013,58,1:16

3Susceptibility Assessment of Landslides Caused by the Wenchuan Earthquake Using a Logistic Regression Model显示文摘The Wenchuan earthquake on May 12,2008 caused numerous collapses,landslides,barrier lakes,and debris flows.Landslide susceptibility mapping is important for evaluation of environmental capacity and also as a guide for post-earthquake reconstruction.In this paper,a logistic regression model was developed within the framework of GIS to map landslide susceptibility.Qingchuan County,a heavily affected area,was selected for the study.Distribution of landslides was prepared by interpretation of multi-temporal and multi-resolution remote sensing images(ADS40 aerial imagery,SPOT5 imagery and TM imagery,etc.) and field surveys.The Certainly Factor method was used to find the influencial factors,indicating that lithologic groups,distance from major faults,slope angle,profile curvature,and altitude are the dominant factors influencing landslides.The weight of each factor was determined using a binomial logistic regression model.Landslide susceptibility mapping was based on spatial overlay analysis and divided into five classes.Major faults have the most significant impact,and landslides will occur most likely in areas near the faults.Onethird of the area has a high or very high susceptibility,located in the northeast,south and southwest,including 65.3% of all landslides coincident with the earthquake.The susceptibility map can reveal the likelihood of future failures,and it will be useful for planners during the rebuilding process and for future zoning issues.SU Fenghuan 2010Journal of Mountain Science2010,7,3:14
4A cyclic nucleotide-gated channel mediates cytoplasmic calcium elevation and disease resistance in rice显示文摘The transient elevation of cytoplasmic calcium is essential for pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI).However,the calcium channels responsible for this process have remained unknown.Here,we show that rice CDSI(CELL DEATH and SUSCEPTIBLE to BLAST 1)encoding OsCNGC9;a cyclic nucleotide-gated channel protein,positively regulates the resistance to rice blast disease.We show that OsCNGC9 mediates PAMP-induced Ca2+influx and that this event is critical for PAMPs-triggered ROS burst and induction of PTI-related defense gene expression.We further show that a PTI related receptor-lih cytoplasmic kinase OsRLCK185 physically interacts with and phosphorylates OsCNGC9 to activate its channel activity.Our results suggest a signaling cascade linking pattern recognition to calcium channel activation,which is required for initiation of PTI and disease resistance in rice.Jiachang Wang Xi Liu An Zhang Yulong Ren Fuqing Wu Gang Wang Yang Xu Cailin Lei Shanshan Zhu Tian Pan Yongfei Wang Huan Zhang Fan Wang Yan-Qiu Tan Yupeng Wang Xin Jin Sheng Luo Chunlei Zhou Xiao Zhang Jinling Liu Shuai Wang Lingzhi Meng Yihua Wang Xi Chen Qibing Lin Xin Zhang Xiuping Guo Zhijun Cheng Jiulin Wang Yunlu Tian Shijia Liu Ling Jiang Chuanyin Wu Ertao Wang Jian-Min Zhou Yong-Fei Wang Haiyang Wang Jianmin Wan 2019Cell Research2019,29,10:13

6Underlying mechanism of protection from hypoxic injury seen with n-butanol extract of Potentilla anserine L. in hippocampal neurons显示文摘The alcohol and n-butanol extract of Potentilla anserine L. significantly protects myocardium from acute ischemic injury. However, its effects on rat hippocampal neurons and the mechanism of protection remain unclear. In this study, primary cultured hippocampal neurons from neonatal rats were incubated in 95% N2 and 5% CO2 for 4 hours. Results indicated that hypoxic injury decreased the viability of neurons, increased the expression levels of caspase-9 and caspase-3 mRNA, as well as cytochrome c, Caspase-9, and Caspase-3 protein. Pretreatment with 0.25, 0.062 5, 0.015 6 mg/mL n-butanol extract of Potentilla anserine L. led to a significant increase in cell viability. Expression levels of caspase-9 and caspase-3 mRNA, as well as cytochrome c, Caspase-9, and Caspase-3 protein, were attenuated. The neuroprotective effect of n-butanol extract of Potentilla anserine L. was equivalent to tanshinone IIA. Our data suggest that the n-butanol extract of Potentilla anserine L. could protect primary hippocampal neurons from hypoxic injury by deactivating mitochondrial cell death.Xiaojing Qin Lingzhi Li Qi Lv Baoguo Yu ShuwangYang Tao He Yongliang Zhang 2012Neural Regeneration Research2012,7,33:11

8Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype.Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu 2021Cell Research2021,31,3:9
9On the Kinematic Characteristics and Dynamic Process of Boundary faults of the Nansha Ultra-crust Layer-Block显示文摘The Nansha ultra-crust layer-block is confined by ultra-crustal boundary faults of distinctive features, bordering the Kangtai-Shuangzi-Xiongnan extensional faulted zone on the north, the Baxian-Baram-Yoca-Cuyo nappe faulted zone on the south, the Wan’an-Natuna strike-slip tensional faulted zone on the west and the Mondoro-Panay strike-slip compressive faulted zone on the east. These faults take the top of the Nansha asthenosphere as their common detachmental surface. The Cenozoic dynamic process of the ultra-crust layer-block can be divided into four stages: K2-E21, during which the northern boundary faults extended, this ultra-crust layer-block was separated from the South China-Indosinian continental margin, the Palaeo-South China Sea subducted southwards and the Sibu accretion wedge was formed; E22-E31, during which the Southwest sub-sea basin extended and orogeny was active due to the collision of the Sibu accretion wedge; E32-N11, during which the central sub-sea basin extended, the MiriLIU Hailing SUN Yan GUO Lingzhi SHU Liangshu YANG Shukang ZHOU Di ZHANG Yixiang 1999Acta Geologica Sinica(English Edition)1999,73,4:9
10An update: Epstein-Barr virus and immune evasion via microRNA regulation显示文摘Epstein-Barr virus(EBV) is an oncogenic virus that ubiquitously establishes life-long persistence in humans. To ensure its survival and maintain its B cell transformation function, EBV has developed powerful strategies to evade host immune responses. Emerging evidence has shown that micro RNAs(mi RNAs) are powerful regulators of the maintenance of cellular homeostasis. In this review, we summarize current progress on how EBV utilizes mi RNAs for immune evasion. EBV encodes mi RNAs targeting both viral and host genes involved in the immune response. The mi RNAs are found in two gene clusters, and recent studies have demonstrated that lack of these clusters increases the CD4^+ and CD8^+ T cell response of infected cells. These reports strongly indicate that EBV mi RNAs are critical for immune evasion. In addition, EBV is able to dysregulate the expression of a variety of host mi RNAs, which influence multiple immune-related molecules and signaling pathways. The transport via exosomes of EBV-regulated mi RNAs and viral proteins contributes to the construction and modification of the inflammatory tumor microenvironment.During EBV immune evasion, viral proteins, immune cells, chemokines, pro-inflammatory cytokines, and pro-apoptosis molecules are involved. Our increasing knowledge of the role of mi RNAs in immune evasion will improve the understanding of EBV persistence and help to develop new treatments for EBV-associated cancers and other diseases.Lielian Zuo Wenxin Yue Shujuan Du Shuyu Xin Jing Zhang Lingzhi Liu Guiyuan Li Jianhong Lu 2017Virologica Sinica2017,32,3:9
11Ab initio study of the effects of Ag/Mn doping on the electronic structure of LiFePO_4显示文摘Based on density functional theory (DFT) of the first-principle for the cathode materials of lithium ion battery, the electronic structures of Li(Fe1-xMex)PO4 (Me = Ag/Mn, x = 0―0.40) are calculated by plane wave pseudo-potential method using Cambridge serial total energy package (CASTEP) program. The calculated results show that the Fermi level of mixed atoms Fe1-xAgx moves into its conduction bands (CBs) due to the Ag doping. The Li(Fe1-xAgx)PO4 system displays the periodic direct semiconductor characteristic with the increase of Ag-doped concentration. However, for Fe1-xMnx mixed atoms, the Fermi level is pined at the bottom of conduction bands (CBs), which is ascribed to the interaction be-tween Mn(3d) electrons and Fe(4s) electrons. The intensity of the partial density of states (PDOS) near the bottom of CBs becomes stronger with the increase of Mn-doped concentration. The Fermi energy of the Li(Fe1-xMnx)PO4 reaches maximum at x = 0.25, which is consistent with the experimental value of x = 0.20. The whole conduction property of Mn-doped LiFePO4 is superior to that of Ag-doped LiFePO4 cathode material, but the structural stability is reverse.HOU XianHua HU SheJun LI WeiShan ZHAO LingZhi RU Qiang YU HongWer HUANG ZhaoWen 2008Chinese Science Bulletin2008,53,11:9
12Lithium intercalation/de-intercalation behavior of a composite Sn/C thin film fabricated by magnetron sputtering显示文摘A tin film of 320 nm in thickness on Cu foil and its composite film with graphite of ~50 nm in thickness on it were fabricated by magnetron sputtering. The surface morphology, composition, surface distributions of alloy elements, and lithium intercalation/de-intercalation behaviors of the fabricated films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), electron probe microanalyzer (EPMA), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma atomic emission spectrometry (ICP), cyclic voltammetry (CV), and galvanostatic charge/discharge (GC) measurements. It is found that the lithium intercalation/de-intercalation behavior of the Sn film can be significantly improved by its composite with graphite. With cycling, the discharge capacity of the Sn film without composite changes from 570 mAh/g of the 2nd cycle to 270 mAh/g of the 20th cycle, and its efficiency for the discharge and charge is between 90% and 95%. Nevertheless, the discharge capacity of the composite Sn/C film changes from 575 mAh/g of the 2nd cycle to 515 mAh/g of the 20th cycle, and its efficiency for the discharge and charge is between 95% and 100%. The performance improvement of tin by its composite with graphite is ascribed to the retardation of the bulk tin cracking from volume change during lithium intercalation and de-intercalation, which leads to the pulverization of tin.ZHAO Lingzhi HU Shejun LI Weishan LI Liming HOU Xianhua 2008Rare Metals2008,27,5:8
13Research on Diageneses of Cambrian Shoal Facies Carbonate Rocks in the Xiadong Area, Hubei Province显示文摘With continuous outcrops, developed shoal facies rocks, complete types of diagenesis and changeable diagenetic environments, Cambrian strata are well developed in the Xiadong area, Yichang, Hubei Province. Under the combined influence of numerous diageneses, secondary pores can be formed, which result in better reservoir properties of the rock strata.The Cambrian rocks in this area consist of mainly carbonate rocks and secondarily detrital rocks. The carbonate rocks are dominated by grainstones including wormkalk, calcirudite-calcarenite, oolitic limestone and oncolitic limestone. Graded bedding and cross bedding are well developed in the strata, which indicates that the formation environment is of a high-energy shoal facies.In this area, there has developed a sequence of stable Cambrian platform carbonate deposition. The evolution trend is as follows: open sea shelf facies? intertidal low-energy restricted sea facies? intertidal high-energy shoal facies? coastal shoal facies? evaporite tidal-flat facies.The diageneses that the strata have experienced mainly include dolomitization, dedolomitization and dissolution, which are constructive diageneses for the formation of secondary pores, such as intercrystal pores, intercrystal solution pores, gypsum mold pores and caverns of dolomite.The diagenetic facies intervals can be divided into the unitary and the compound ones, totalling 22 in the area.In the early atmospheric fresh-water diagenetic environment and the late epidiagenetic environment, Cambrian rocks, especially dolomite of the Middle and Upper Cambrian, experienced extensive and profound fresh water corrosion, forming pore intervals with a porosity ranging from 5% to 15%.ZHANG Xiulian and JIANG Lingzhi Department of Geology, Peking University, Beijing 100871 2001Acta Geologica Sinica(English Edition)2001,75,2:7
14Snaill is involved in de novo cardiac fibrosis after myocardial infarction in mice显示文摘Epithelialmesenchymal 转变(EMT ) 是在心肌的梗塞(MI ) 以后的心脏的纤维变性的重要机制。然而,它仍然保持不清楚是否 Snail1, EMT 的一个重要管理者,涉及心脏的纤维变性。在这研究,我们在老鼠探索了 Snail1 和心脏的纤维变性 markerperiostinafter MI 的表示模式然后在老鼠在 MI 以后调查了在 Snail1 和 periostin 之间的合作表示。我们的结果证明 Snail1 和 periostin 的 mRNA 和蛋白质层次显著地在梗塞区域被增加。Snail1 表示模式看起来在在 MI 以后的 14 天以内寓言。另外在 MI 以后,所有 Snail1 积极的房间能表示 periostin。这些结果显示 Snail1 主要在梗塞区域被激活并且涉及 de novo 在在老鼠的 MI 以后的心脏的纤维变性。因此,它是在为在 MI 以后的室的改变的药干预的发展的一个潜在的分子的目标。Yajie Liu Jianlin Du Jin Zhang Minjie Weng Xiaoqun Li Di Pu Lingzhi Gao Songbai Deng Shuang Xia Qiang She 2012Acta Biochimica et Biophysica Sinica2012,44,11:7
15MiR-148a inhibits angiogenesis by targeting ERBB3显示文摘MicroRNAs (miRNAs) play an important role in carcinogenesis in various solid cancers including breast can-cer. Down-regulation of microRNA-148a (miR-148a) has been reported in certain cancer types. However, the biological role of miR-148a and its related targets in breast cancer are unknown yet. In this study, we showed that the level of miR-148a was lower in MCF7 cells than that in MCF10A cells. V-erb-b2 erythroblastic leukemia viral oncogene homolog 3 (ERBB3) is a direct target of miR-148a in human breast cancer cells through direct binding of miR-148a to ERBB3 3'-UTR region. Overexpression of miR-148a in MCF7 cells inhibited ERBB3 expression, blocked the downstream pathway activation including activation of AKT, ERK1/2, and p70S6K1, and decreased HIF-1α expression. Furthermore, forced expression of miR-148a attenuated tumor angiogenesis in vivo. Our re-sults identify ERBB3 as a direct target of miR-148a, and provide direct evidence that miR-148a inhibits tumor an-giogenesis through ERBB3 and its downstream signaling molecules. This information would be helpful for target-ing the miR-148a/ERBB3 pathway for breast cancer prevention and treatment in the future.Jing Yu Qi Li Qing Xu Lingzhi Liu Binghua Jiang 2011The Journal of Biomedical Research2011,25,3:6
16Monoclonal neutralizing antibodies against EV71 screened from mice immunized with yeast-produced virus-like particles显示文摘Periodic outbreaks of hand, foot and mouth disease(HFMD) occur in children under 5 years old, and can cause death in some cases. The C4 strain of enterovirus 71(EV71) is the main pathogen that causes HFMD in China. Although no drugs against EV71 are available, some studies have shown that candidate vaccines or viral capsid proteins can produce anti-EV71 immunity. In this study, female BABL/c mice(6–8 weeks old) were immunized with virus-like particles(VLPs) of EV71 produced in yeast to screen for anti-EV71 antibodies. Two hybridomas that could produce neutralizing antibodies against EV71 were obtained. Both neutralizing m Abs(D4 and G12) were confirmed to bind the VP1 capsid protein of EV71, and could protect > 95% cells from 100 TCID50 EV71 infection at 25 μg/m L solution(lowest concentration). Those two neutralizing m Abs identified in the study may be promising candidates in development for m Abs to treat EV71 infection, and utilized as suitable reagents for use in diagnostic tests and biological studies.Tao Lin Lingzhi Xianyu Songya Lyu 2015Virologica Sinica2015,30,3:6
17Dead lithium phase investigation of Sn-Zn alloy as anode materials for lithium ion battery显示文摘In this work, based on First-principle plane wave pseudo-potential method, we have carried out an in-depth study on the possible dead lithium phase of Sn-Zn alloy as anode materials for lithium ion batteries. Through investigation, we found that the phases LixSn4Zn4(x = 2, 4, 6, 8) contributed to re-versible capacity, while the phases LixSn4Zn8-(x-4)(x = 4.74, 7.72) led to capacity loss due to high forma-tion energy, namely, they were the dead lithium phases during the charge/discharge process. And we come up with a new idea that stable lithium alloy phase with high lithiation formation energy (dead lithium phase) can also result in high loss of active lithium ion, besides the traditional expression that the formation of solid electrolyte interface film leads to high capacity loss.HUANG ZhaoWen HU SheJun HOU XianHua RU Qiang YU HongWen ZHAO LingZhi LI WeiShan 2009Chinese Science Bulletin2009,54,6:6
18Acute high-altitude hypoxic brain injury Identification of ten differential proteins显示文摘Hypobaric hypoxia can cause severe brain damage and mitochondrial dysfunction,and is involved in hypoxic brain injury.However,little is currently known about the mechanisms responsible for mitochondrial dysfunction in hypobaric hypoxic brain damage.In this study,a rat model of hypobaric hypoxic brain injury was established to investigate the molecular mechanisms associated with mitochondrial dysfunction.As revealed by two-dimensional electrophoresis analysis,16,21,and36 differential protein spots in cerebral mitochondria were observed at 6,12,and 24 hours post-hypobaric hypoxia,respectively.Furthermore,ten protein spots selected from each hypobaric hypoxia subgroup were similarly regulated and were identified by mass spectrometry.These detected proteins included dihydropyrimidinase-related protein 2,creatine kinase B-type,isovaleryl-CoA dehydrogenase,elongation factor Ts,ATP synthase beta-subunit,3-mercaptopyruvate sulfurtransferase,electron transfer flavoprotein alpha-subunit,Chain A of 2-enoyl-CoA hydratase,NADH dehydrogenase iron-sulfur protein 8 and tropomyosin beta chain.These ten proteins are all involved in the electron transport chain and the function of ATP synthase.Our findings indicate that hypobaric hypoxia can induce the differential expression of several cerebral mitochondrial proteins,which are involved in the regulation of mitochondrial energy production.Jianyu Li Yuting Qi Hui Liu Ying Cui Li Zhang Haiying Gong Yaxiao Li Lingzhi Li Yongliang Zhang 2013Neural Regeneration Research2013,8,31:6
19Synthesis of aminoalkylsilanes with oligo(ethylene oxide) unit as multifunctional electrolyte additives for lithium-ion batteries显示文摘Aminoalkylsilanes with oligo(ethylene oxide) units were designed and synthesized as multifunctional electrolyte additives for lithium-ion batteries. The chemical structures were fully characterized by nuclear magnetic resonance (NMR) spectroscopy and their thermal properties, viscosities, electrochemical windows, and ionic conductivities were systematically measured. With adding one of these compounds (1 vol. %, DSC3N1) in the baseline electrolyte 1.0 M LiPF 6 in EC: DEC (1:1, in volume), Li/LiCoO 2 half cell tests showed an improved cyclability after 100 cycles and improved rate capability at 5C rate condition. Electrochemical impedance spectroscopy (EIS), X-ray photoelectron spectroscopy (XPS), and energy dispersive spectroscopic (EDS) analysis confirmed the acid scavenging function and film forming capability of DSC3N1. These results demonstrated that the multifunctional organosilicon compounds have considerable potential as additives for use in lithium-ion batteries.WANG JingLun LUO Hao MAI YongJin ZHAO XinYue ZHANG LingZhi 2013Science China Chemistry2013,56,6:5
