1Immobilization of arsenic in soils by stabilized nanoscale zero-valent iron, iron sulfide (FeS), and magnetite (Fe_3O_4) particles显示文摘Arsenic is a widespread contaminant in soils and groundwater. While various iron-based materials have been studied for immobilizing arsenic in contaminated soils, the feasibility of stabilized iron-based nanoparticles has not been reported. This study investigates the effectiveness of using three types of starch-stabilized iron-based nanoparticles, including zero-valent iron (ZVI), iron sulfide (FeS), and magnetite (Fe3O4), for immobilization of arsenic in two representative As-contaminated soils (an orchard soil and a fire range soil). To test the effect of the nanoparticles on the arsenic leachability, As-contaminated soils were amended with the nanoparticles at various Fe/As molar ratios (5:1―100:1) and contact time (3 and 7 d). After three days' treatments of a field-contaminated sandy soil, the PBET-based bioaccessibility of As decreased from an initial (71.3±3.1)% (mean±SD) to (30.9±3.2)% with ZVI, (37.6±1.2)% with FeS, and (29.8± 3.1)% with Fe3O4 at an Fe/As molar ratio of 100:1. The TCLP-based leachability of arsenic in a spiked fire range soil decreased from an initial (0.51±0.11)% to (0.24±0.03)%, (0.27±0.04)% and (0.17±0.04)% by ZVI, FeS, and Fe3O4 nanoparticles, respectively. The Fe3O4 nanoparticles appeared to be more effective (5% or more) than other nanoparticles for immobilizing arsenic. When the two soils were compared, the treatment is more effective on the orchard soil that has a lower iron content and higher initial leachability than on the range soil that already has a high iron content. These results suggest that these innocuous iron-based nanoparticles may serve as effective media for immobilization of As in iron-deficient soils, sediments or solid wastes.ZHANG MeiYi WANG Yu ZHAO DongYe PAN Gang 2010Chinese Science Bulletin2010,55,4:16
2Dysfunction of PLA2G6 and CYP2C44-associated network signals imminent carcinogenesis from chronic inflammation to hepatocellular carcinoma显示文摘很少长期的发炎怎么贡献 hepatocellular 癌(HCC ) 的前进被知道,特别癌症的开始。揭开从长期的发炎的批评转变到在网络水平的 HCC 和分子的机制,我们用我们的动态网络 biomarker (DNB ) 分析了土拨鼠肝炎 virus/c-myc 鼠标和匹配年龄的 wt-C57BL/6 鼠标的时间系列 proteomic 数据模型。DNB 分析显示在转基因的老鼠的出生以后的第 5 月是癌症开始的批评时期,就在批评转变前,它与临床的症状一致。同时,联系 DNB 的网络在批评转变前后显示出蛋白质表示和 coexpression 层次的激烈的倒置。DNB, PLA2G6 和 CYP2C44 的二个成员,与他们的联系差别一起表示了蛋白质,被发现导致 arachidonic 酸新陈代谢的机能障碍,进一步通过短暂受体潜力隧道的煽动性的调停人规定激活煽动性的回答,并且最后导致肝 detoxification 和恶意的转变的缺陷到癌症。作为一个 c-Myc 目标, PLA2G6 断然在表示与 c-Myc 相关,显示出从减少到在 carcinogenesis 期间增加的一个趋势,与在批评转变的最小的点或付小费给的点。相应 PLA2G6 和 c-Myc 的如此的趋势也在人的 hepatocarcinogenesis 期间被观察,与在高级 dysplastic 小瘤(就在 carcinogenesis 前的一个阶段) 的最小的点。我们的学习暗示 PLA2G6 可能在 hepatocarcinogenesis 期间作为象著名 c-Myc 一样的 oncogene 工作,当 PLA2G6 和 c-Myc 的 downregulation 能是显示逼近的 carcinogenesis 的一个警告信号时。Meiyi Li Chen Li Wei-Xin Liu Conghui Liu Jingru Cui Qingrun Li Hong Ni Yingcheng Yang Chaochao Wu Chunlei Chen Xing Zhen Tao Zeng Mujun zhao Lei Chen Jiarui Wu Rong Zeng Luonan Chen 2017Journal of Molecular Cell Biology2017,9,6:12
3Applications of Lithium-Ion Batteries in Grid-Scale Energy Storage Systems显示文摘In the electrical energy transformation process,the grid-level energy storage system plays an essential role in balancing power generation and utilization.Batteries have considerable potential for application to grid-level energy storage systems because of their rapid response,modularization,and flexible installation.Among several battery technologies,lithium-ion batteries(LIBs)exhibit high energy efficiency,long cycle life,and relatively high energy density.In this perspective,the properties of LIBs,including their operation mechanism,battery design and construction,and advantages and disadvantages,have been analyzed in detail.Moreover,the performance of LIBs applied to grid-level energy storage systems is analyzed in terms of the following grid services:(1)frequency regulation;(2)peak shifting;(3)integration with renewable energy sources;and(4)power management.In addition,the challenges encountered in the application of LIBs are discussed and possible research directions aimed at overcoming these challenges are proposed to provide insight into the development of grid-level energy storage systems.Tianmei Chen Yi Jin Hanyu Lv Antao Yang Meiyi Liu Bing Chen Ying Xie Qiang Chen 2020Transactions of Tianjin University2020,26,3:9
4CeO_2/CuO catalysts using different template agent for preferential CO oxidation in H_2-rich stream显示文摘The CeO_2/CuO catalysts using different template agent(F68 L64, F127 and P123) were synthesized by the simple template and impregnation method. They were characterized by FESEM, XRD, N2 physisorption and H2-TPR techniques. It is found that the CeO_2/CuO catalysts are double pore distribution, and CeO_2 can enter into the gap of CuO supports and form the contact interface of copper and cerium. Among the asprepared catalysts, the CeO_2/CuO-F127 catalyst displays better activity at lower temperature and the CeO_2/CuO-P123 catalyst presents higher activity at higher temperature. The CeO_2/CuO-P123 catalyst has the smallest crystallite sizes of CuO and CeO_2 as well as the largest size of cubes, which may improve the interaction of copper and cerium and enhance the performance of CO oxidation.Xiaolin Yan Aiai Zhang Meiyi Gao Shanghong Zeng 2017Journal of Rare Earths2017,35,12:5
5Edge biomarkers for classification and prediction of phenotypes显示文摘In general,a disease manifests not from malfunction of individual molecules but from failure of the relevant system or network,which can be considered as a set of interactions or edges among molecules.Thus,instead of individual molecules,networks or edges are stable forms to reliably characterize complex diseases.This paper reviews both traditional node biomarkers and edge biomarkers,which have been newly proposed.These biomarkers are classified in terms of their contained information.In particular,we show that edge and network biomarkers provide novel ways of stably and reliably diagnosing the disease state of a sample.First,we categorize the biomarkers based on the information used in the learning and prediction steps.We then briefly introduce conventional node biomarkers,or molecular biomarkers without network information,and their computational approaches.The main focus of this paper is edge and network biomarkers,which exploit network information to improve the accuracy of diagnosis and prognosis.Moreover,by extracting both network and dynamic information from the data,we can develop dynamical network and edge biomarkers.These biomarkers not only diagnose the immediate pre-disease state but also detect the critical molecules or networks by which the biological system progresses from the healthy to the disease state.The identified critical molecules can be used as drug targets,and the critical state indicates the critical point of disease control.The paper also discusses representative biomarker-based methods.ZENG Tao ZHANG WanWei YU XiangTian LIU XiaoPing LI MeiYi LIU Rui CHEN LuoNan 2014Science China(Life Sciences)2014,57,11:5
6Surface and intrinsic contributions to extinction properties of ZnSe quantum dots显示文摘This work studies extinction properties of ZnSe quantum dots terminated with either Se-surface or Zn-surface(Se-ZnSe or Zn-ZnSe QDs).In addition to commonly observed photoluminescence quenching by anionic surface sites,Se-ZnSe QDs are found to show drastic signatures of Se-surface states in their UV-visible(Vis)absorption spectra.Similar to most QDs reported in literature,monodisperse Zn-ZnSe QDs show sharp absorption features and blue-shifted yet steep absorption edge respect to the bulk bandgap.However,for monodisperse Se-ZnSe QDs,all absorption features are smeared and a low-energy tail is identified to extend to an energy window below the bulk ZnSe bandgap.Along increasing their size,a cyclic growth of ZnSe QDs switches their surface from Zn-terminated to Se-terminated ones,which confirms that the specific absorption signatures are reproducibly repeated between those of two types of the QDs.Though the extinction coefficients per unit of Se-ZnSe QDs are always larger than those of Zn-ZnSe QDs with the same size,both of them approach the same bulk limit.In addition to contribution of the lattice,extinction coefficients per nanocrystal of Zn-ZnSe QDs show an exponential term against their sizes,which is expected for quantum-confinement enhancement of electron-hole wavefunction overlapping.For Se-ZnSe QDs,there is the third term identified for their extinction coefficients per nanocrystal,which is proportional to the square of size of the QDs and consistent with surface contribution.Shangxin Lin Jiongzhao Li Chaodan Pu Hairui Lei Meiyi Zhu Haiyan Qin Xiaogang Peng 2020Nano Research2020,13,3:5

8Whole exome sequencing identifies an AMBN missense mutation causing severe autosomal-dominant amelogenesis imperfecta and dentin disorders显示文摘Tooth development is a complex process that involves precise and time-dependent orchestration of multiple genetic, molecular,and cellular interactions. Ameloblastin(AMBN, also named 'amelin' or 'sheathlin') is the second most abundant enamel matrix protein known to have a key role in amelogenesis. Amelogenesis imperfecta(AI [MIM: 104500]) refers to a genetically and phenotypically heterogeneous group of conditions characterized by inherited developmental enamel defects. The hereditary dentin disorders comprise a variety of autosomal-dominant genetic symptoms characterized by abnormal dentin structure affecting either the primary or both the primary and secondary teeth. The vital role of Ambn in amelogenesis has been confirmed experimentally using mouse models. Only two cases have been reported of mutations of AMBN associated with non-syndromic human AI. However, no AMBN missense mutations have been reported to be associated with both human AI and dentin disorders.We recruited one kindred with autosomal-dominant amelogenesis imperfecta(ADAI) and dentinogenesis imperfecta/dysplasia characterized by generalized severe enamel and dentin defects. Whole exome sequencing of the proband identified a novel heterozygous C-T point mutation at nucleotide position 1069 of the AMBN gene, causing a Pro to Ser mutation at the conserved amino acid position 357 of the protein. Exfoliated third molar teeth from the affected family members were found to have enamel and dentin of lower mineral density than control teeth, with thinner and easily fractured enamel, short and thick roots, and pulp obliteration. This study demonstrates, for the first time, that an AMBN missense mutation causes non-syndromic human AI and dentin disorders.Ting Lu Meiyi Li Xiangmin Xu Jun Xiong Cheng Huang Xuelian Zhang Aiqin Hu Ling Peng Decheng Cai Leitao Zhang Buling Wu Fu Xiong 2018International Journal of Oral Science2018,10,4:3
9Dynamic edge-based biomarker non-invasively predicts hepatocellular carcinoma with hepatitis B virus infection for individual patients based on blood testing显示文摘Hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC) is a major cause of cancer-related deaths in Asia and Africa. Developing effective and non-invasive biomarkers of HCC for individual patients remains an urgent task for early diagnosis and convenient monitoring. Analyzing the transcriptomic profiles of peripheral blood mononuclear cells from both healthy donors and patients with chronic HBV infection in different states (i.e. HBV carrier, chronic hepatitis B, cirrhosis, and HCC), we identified a set of 19 candidate genes according to our algorithm of dynamic network biomarkers. These genes can both characterize different stages during HCC progression and identify cirrhosis as the critical transition stage before carcinogenesis. The interaction effects (i.e. coexpressions) of candidate genes were used to build an accurate prediction model: the so-called edge-based biomarker. Considering the convenience and robustness of biomarkers in clinical applications, we performed functional analysis, validated candidate genes in other independent samples of our collected cohort, and finally selected COL5A1, HLA-DQB1, MMP2, and CDK4 to build edge panel as prediction models. We demonstrated that the edge panel had great performance in both diagnosis and prognosis in terms of precision and specificity for HCC, especially for patients with alpha-fetoprotein-negative HCC. Our study not only provides a novel edge-based biomarker for non-invasive and effective diagnosis of HBV-associated HCC to each individual patient but also introduces a new way to integrate the interaction terms of individual molecules for clinical diagnosis and prognosis from the network and dynamics perspectives.Yiyu Lu Zhaoyuan Fang Meiyi Li Chen Qian Tao Zeng Lina Lu Qilong Chen Hui Zhang Qianmei Zhou Yan Sun Xuefeng Xue Yiyang Hu Luonan Chen Shibing Su 2019Journal of Molecular Cell Biology2019,11,8:3

20Women's Dress In Modern China (3)显示文摘CHINA’s Revolution of 1911 was followed closely by a clothing revolution sparked from the politics of the period. Simply stated, the Revolution of 1911 brought an end to dress being the mark of social status. Closer scrutiny of the form and style of clothing reveals that striking changes took place between the 1920s-1930s.L MEIYI LIU QIAN 1996Women of China1996,,11:0
