2规模化秸秆沼气发酵反应器中微生物群落特征显示文摘采用末端限制性多态性分析(T-RFLP)和克隆文库构建相结合的研究方法,对以秸秆为唯一或主要原料的四个沼气发酵反应器中的细菌和古菌群落特征进行分析,结果表明:(1)供试秸秆沼气反应器中细菌种类十分丰富,分属于9个门,其中厚壁菌门(Firmicutes)、变形菌门(Proteobacteria)与拟杆菌门(Bacteroidetes)为优势种群,在四个沼气反应器中的相对丰度分别为19.3%~47.2%、4.8%~24.3%与2.5%~15.5%。水解与发酵性细菌为各反应器中的优势种群;(2)古菌种类明显少于细菌,均属于甲烷杆菌纲(Methanobacteria)和甲烷微菌纲(Methanomicrobia)。在以秸秆为唯一原料的反应器中,甲烷鬃菌属(Methanosaeta)为优势种群,相对丰度为69.2%~71.9%;而在添加猪粪的反应器中,甲烷八叠球菌属(Methanosarcina)为优势种群,相对丰度为73.1%。张蕾 梁军锋 崔文文 杜连柱 高文萱 Xinmei Feng Anna Schnürer 2014农业环境科学学报2014,33,3:15
3Myelin Oligodendrocyte Glycoprotein-IgG Contributes to Oligodendrocytopathy in the Presence of Complement, Distinct from Astrocytopathy Induced by AQP4-IgG显示文摘Immunoglobulin G against myelin oligodendrocyte glycoprotein(MOG-Ig G) is detectable in neuromyelitis optica spectrum disorder(NMOSD) without aquaporin-4 Ig G(AQP4-Ig G), but its pathogenicity remains unclear.In this study, we explored the pathogenic mechanisms of MOG-Ig G in vitro and in vivo and compared them with those of AQP4-Ig G. MOG-Ig G-positive serum induced complement activation and cell death in human embryonic kidney(HEK)-293 T cells transfected with human MOG. In C57 BL/6 mice and Sprague-Dawley rats, MOG-Ig G only caused lesions in the presence of complement. Interestingly, AQP4-Ig G induced astroglial damage, while MOGIg G mainly caused myelin loss. MOG-Ig G also induced astrocyte damage in mouse brains in the presence ofcomplement. Importantly, we also observed ultrastructural changes induced by MOG-Ig G and AQP4-Ig G. These findings suggest that MOG-Ig G directly mediates cell death by activating complement in vitro and producing NMOSDlike lesions in vivo. AQP4-Ig G directly targets astrocytes,while MOG-Ig G mainly damages oligodendrocytes.Ling Fang Xinmei Kang Zhen Wang Shisi Wang Jingqi Wang Yifan Zhou Chen Chen Xiaobo Sun Yaping Yan Allan G.

4Contamination of Phthalate Esters in Vegetable Agriculture and Human Cumulative Risk Assessment显示文摘Phthalate esters(PAEs), which can disturb human endocrine system, have been widely detected in vegetable greenhouse agriculture in China. To investigate the effects of environmental factors on PAEs in soils, pollution sources were identified, and the cumulative risks of PAEs to humans through vegetables in the diet were evaluated in this study. Ninety-eight vegetable samples were collected from 10 markets along with 128 vegetable and 111 soil samples from agricultural greenhouses and open field. All soil and vegetable samples were contaminated with PAEs, and the total concentrations of the 5 PAEs, including dimethyl phthalate(DMP), diethyl phthalate(DEP), di-iso-butyl phthalate(DiBP), di-n-butyl phthalate(DnBP), and di-2-ethylhexyl phthalate(DEHP), were in the ranges of 0.26–2.53 mg kg^(-1) for soils and 0.95–8.09 mg kg^(-1) for vegetables. Three components extracted from principle component analysis could explain 51.2%, 19.8%, and 15.3% of the total variance of the 5 PAEs in soils, which may represent three major sources of PAEs, i.e., wastewater irrigation, application of fertilizers and pesticides, and plastic film. Long-term greenhouse cultivation could accumulate DEHP in soils, and a higher soil Fe Ox content reduced the Dn BP concentration. Based on a survey of vegetables in the diet, the hazard index of PAEs was < 0.15 for individuals in different cities. The exposure of PAEs through vegetable intake was higher than the total exposure from other food stuffs, inhalation, and dermal absorption. More attention should be given to controlling PAEs in greenhouse vegetables.CHEN Ning SHUAI Wenjuan HAO Xinmei ZHANG Huichun ZHOU Dongmei GAO Juan 2017Pedosphere2017,27,3:12
5IDENTITY-BASED MULTISIGNATURE AND AGGREGATE SIGNATURE SCHEMES FROM M-TORSION GROUPS显示文摘An identity-based multisignature scheme and an identity-based aggregate signature scheme are proposed in this paper. They are both from m-torsion groups on super-singular elliptic curves or hyper-elliptic curves and based on the recently proposed identity-based signature scheme of Cha and Cheon. Due to the sound properties of m-torsion groups and the base scheme, it turns out that our schemes are very simple and efficient. Both schemes are proven to be secure against adaptive chosen message attack in the random oracle model under the normal security notions with the assumption that the Computational Diffie-Hellman problem is hard in the m-torsion groups.Cheng Xiangguo Liu Jingmei Guo Lifeng Wang Xinmei 2006Journal of Electronics(China)2006,23,4:11

7FKF1 F-box protein promotes flowering in part by negatively regulating DELLA protein stability under long-day photoperiod in Arabidopsis^FA显示文摘FLAVIN-BINDING KELCH REPEAT F-BOX 1(FKF1)encodes an F-box protein that regulates photoperiod flowering in Arabidopsis under long-day conditions(LDs).Gibberellin(GA)is also important for regulating flowering under LDs.However,how FKF1 and the GA pathway work in concert in regulating flowering is not fully understood.Here,we showed that the mutation of FKF1 could cause accumulation of DELLA proteins,which are crucial repressors in GA signaling pathway,thereby reducing plant sensitivity to GA in flowering.Both in vitro and in vivo biochemical analyses demonstrated that FKF1 directly interacted with DELLA proteins.Furthermore,we showed that FKF1 promoted ubiquitination and degradation of DELLA proteins.Analysis of genetic data revealed that FKF1 acted partially through DELLAs to regulate flowering under LDs.In addition,DELLAs exerted a negative feedback on FKF1 expression.Collectively,these findings demonstrate that FKF1 promotes flowering partially by negatively regulating DELLA protein stability under LDs,and suggesting a potential mechanism linking the FKF1 to the GA signaling DELLA proteins.Jindong Yan Xinmei Li Bingjie Zeng Ming Zhong Jiaxin Yang Piao Yang Xin Li Chongsheng He Jianzhong Lin Xuanming Liu Xiaoying Zhao 2020Journal of Integrative Plant Biology2020,62,11:8
8In Situ Synthesis of NaY Zeolite with Coal-Based Kaolin显示文摘NaY zeolites were in-situ synthesized from coal-based kaolin via the hydrothermal method.The effects of various factors on the structure of the samples were extensively investigated. The sampleswere characterized by N2 adsorption, XRD, IR and DTG-DTA methods, and the results show that thecrystallization temperature and amount of added water play an important role in the formation of the zeo-lite structure. The 4A and P zeolites are the competitive phase present in the resulting product. However,NaY zeolites with a higher relative crystallinity, excluding impure crystals and the well hydrothermal sta-bility, can be synthesized from coal-based kaolin. These zeolites possess a larger surface area and a narrowpore size distribution, and this means that optimization of this process might result in a commercial routeto synthesize NaY zeolites from coal-based kaolin.Xinmei Liu, Zifeng Yan, Huaiping Wang, Yantuo LuoState Key Laboratory for Heavy Oil Processing, Key Laboratory of Catalysis, CNPC, University of Petroleum, Dongying 257061, China 2003Journal of Natural Gas Chemistry2003,12,1:8
9Wharton's jelly mesenchymal stem cells differentiate into retinal progenitor cells显示文摘Human Wharton's jelly mesenchymal stem cells were isolated from fetal umbilical cord. Cells were cultured in serum-free neural stem cell-conditioned medium or neural stem cell-conditioned medium supplemented with Dkk-1, a Wnt/β catenin pathway antagonist, and LeftyA, a Nodal signaling pathway antagonist to induce differentiation into retinal progenitor cells. Inverted microscopy showed that after induction, the spindle-shaped or fibroblast-like Wharton's jelly mesenchymal stem cells changed into bulbous cells with numerous processes. Immunofluorescent cytochemical staining and reverse-transcription PCR showed positive expression of retinal progenitor cell markers, Pax6 and Rx, as well as weakly down-regulated nestin expression. These results demonstrate that Wharton's jelly mesenchymal stem cells are capable of differentiating into retinal progenitor cells in vitro.Ying Hu Jun Liang Hongping Cui Xinmei Wang Hua Rong Bin Shao Hao Cui 2013Neural Regeneration Research2013,8,19:7
10A combination of follicle stimulating hormone, estradiol and age is associated with the pregnancy outcome for women undergoing assisted reproduction: a retrospective cohort analysis显示文摘To investigate the effect of basal hormone levels including follicle stimulating hormone(FSH) and estradiol(E2) and age on the pregnancy outcomes in women undergoing in vitro fertilization and embryo transfer(IVF-ET), we designed a retrospective cohort analysis and collected information of patients undergoing IVF between January 2014 and April 2017. We found that young women had much better pregnancy outcomes than older women regardless of the hormone levels. The pregnancy outcomes declined in young women with high basal E2, even though they had normal FSH. Older women with higher FSH had a worse outcome of pregnancy, especially with increased E2 level. The results suggest that a combination of FSH, E2 and age could effectively predict the pregnancy outcome for women undergoing IVF-ET, and we should encourage infertile women with diminished ovarian reserve, especially young infertile women, to try the assisted reproduction as early as possible. After 40-yearold, the cost-benefit ratio should be considered according to the ovarian function.Ziru Jiang Li Jin Weihui Shi Ji Xi Yulian Hu Xinmei Liu Jianzhong Sheng Guolian Ding Hefeng Huang 2019Science China(Life Sciences)2019,62,1:7
11A THRESHOLD BLIND SIGNATURE FROM WEIL PAIRING ON ELLIPTIC CURVES显示文摘The idea behind a (t, n) threshold blind signature is that a user can ask at least t out of n players of a group to cooperate to generate a signature for a message without revealing its content. This paper first presents a new blind signature scheme from Weil pairing on elliptic curves. Based on this scheme, a threshold blind signature scheme is proposed. It is efficient and has the security properties of robustness and unforgeability. In the proposed scheme, the group manger is introduced to take the role of distributing the group secret key to each player. However, he cannot forge the players to generate partial blind signatures (Each partial blind signature depends on not only the secret key of the player, but also a random number the player picks). Compared with a threshold signature with a trusted third party, its advantage is obvious; Compared with a threshold signature without a trusted third party, it is more simple and efficient.Cheng Xiangguo Xu Weidong Wang Xinmei 2006Journal of Electronics(China)2006,23,1:6

13miR-410 induces both epithelial–mesenchymal transition and radioresistance through activation of the PI3K/mTOR pathway in non-small cell lung cancer显示文摘Radiotherapy remains one of the major treatments for non-small cell lung cancer(NSCLC)patients;whereas intrinsic or acquired radioresistance limits its efficacy.Nevertheless,most studies so far have only focused on acquired resistance.The exact mechanisms of intrinsic radioresistance in NSCLC are still unclear.A few studies have suggested that epithelial–mesenchymal transition(EMT)is associated with radioresistance in NSCLC.However,little is known about whether the abnormal expression of specific microRNAs induces both EMT and radioresistance.We previously found that miR-410 has multiple roles as an oncomiRNA in NSCLC.In this study,we revealed that miR-410 overexpression promoted EMT and radioresistance,accompanied by enhanced DNA damage repair both in vitro and in vivo.Conversely,knockdown of miR-410 showed the opposite effects.We further demonstrated that PTEN was a direct target of miR-410 by using bioinformatic tools and dual-luciferase reporter assays,and the miR-410-induced EMT and radioresistance were reversed by PI3K,Akt,and mTOR inhibitors or by restoring the expression of PTEN in NSCLC cells.In addition,we preliminarily found that the expression of miR-410 was positively correlated with EMT and negatively associated with the expression of PTEN in NSCLC specimens.In summary,these results demonstrated that miR-410 is an important regulator on enhancing both NSCLC EMT and radioresistance by targeting the PTEN/PI3K/mTOR axis.The findings suggest that miR-410-induced EMT might significantly contribute to the enhanced radioresistance.Therefore,miR-410 may serve as a potential biomarker or therapeutic target for NSCLC radiotherapy.Yue Yuan Hu Liao Qiang Pu Xixian Ke Xueting Hu Yongfang Ma Xinmei Luo Qianqian Jiang Yi Gong Min Wu Lunxu Liu Wen Zhu 2020Signal Transduction and Targeted Therapy2020,5,1:5

15Research Progress of Refractory High Entropy Alloys:A Review显示文摘Owing to superior comprehensive performance than conventional superalloys at high temperature,refractory high entropy alloy(RHEA)is becoming a promising candidate for the next generation high-temperature material.Herein,contemporary aspects of corresponding development of RHEAs are reviewed to discuss various factors affecting the organization structure and service performance.It mainly covers alloying system and strengthening mechanism,the preparation method,plastic deformation and the related mechanism,as well as microstructure control by heat treatment.Firstly,the alloy systems and strengthening mechanism are introduced.This is followed by different preparation methods and the comparison of strengths and shortcomings based on different RHEAs.Then,hot deformation behavior and plastic deformation under different loadings are analyzed.Based on this,the influence of heat treatment on microstructures prior to and after the deformation is further summarized.Finally,some important research areas to be carried out in future are pointed out.This review will give a deep understanding of the effects of different factors on the service performance and provide scientific guide in designing RHEAs with improved performance.Xiaochang Xie Neng Li Wei Liu Shuai Huang Xiaoyong He Qiuying Yu Huaping Xiong Enhui Wang Xinmei Hou 2022Chinese Journal of Mechanical Engineering2022,35,6:4
16One-pot synthesis of the highly efficient bifunctional Ni-SAPO-11 catalyst显示文摘Hydro isomerization of linear alkanes to branched isomers is an important petrochemical process for production of gasoline with high octane number.Non-noble metal bifunctional catalysts used in this process always suffer from low metal dispersion and poor metal-acid synergy.Herein,a facile one-pot synthesis method was used to simultaneously regulate metal particle sizes and acidity of the Ni-SAPO-11 hydroisomerization catalyst.The physicochemical properties are investigated using XANES,EXAFS,TEM/STEM,FT-IR,XPS,UV-vis and NH_3-TPD.Apart from the highly dispersed nickel nanoparticles with an average diameter of 8 nm,the framework Ni~(2+)ions are generated via substituting framework Al~(3+)ions of the SAPO-11.The formed NiP-OH structures have lower deprotonation energy(DPE)than the SiAl-OH ones,contributing more and stronger acid sites to the Ni-SAPO-11 catalyst.The great metal-acid synergy including high metal to acid sites ratio(n_(Ni)/n_A)and close intimacy is obtained for the Ni-SAPO-11 catalyst.The Ni-SAPO-11 catalyst outperforms the counterpart prepared by the impregnation method and exhibits comparable activity and isomers selectivity to the Pt/SAPO-11 catalyst in the n-hexane hydroisomerization.Yuchao Lyu Weilong Zhan Zhumo Yu Xinmei Liu Ye Yang Xiaoxing Wang Chunshan Song Zifeng Yan 2021Journal of Materials Science & Technology2021,,17:4
17Facile fabrication of three-dimensional interconnected nanoporous N-TiO_2 for efficient photoelectrochemical water splitting显示文摘Three-dimensional(3 D) interconnected porous architectures are expected to perform well in photoelectrochemical(PEC) water splitting due to their high specific surface area as well as favourable porous properties and interconnections. In this work, we demonstrated the facile fabrication of 3 D interconnected nanoporous N-doped TiO_2(N-TiO_2 network) by annealing the anodized 3 D interconnected nanoporous TiO_2(TiO_2 network) in ammonia atmosphere. The obtained N-TiO_2 network exhibited broadened light absorption, and abundant, interconnected pores for improving charge separation, which was supported by the reduced charge transfer resistance. With these merits, a remarkably high photocurrent density at 1.23 V vs. reversible hydrogen electrode(RHE) was realized for the N-TiO_2 network without any co-catalysts or sacrificial reagents, and the photostability can be assured after long term illumination.In view of its simplicity and efficiency, this structure promises for perspective PEC applications.Yingzhi Chen Aoxiang Li Qun Li Xinmei Hou Lu-Ning Wang Zheng-Hong Huang 2018Journal of Materials Science & Technology2018,34,6:4
18Network Coding-based Reliable Broadcast Transmission in Wireless Networks显示文摘Recently, network coding has been applied to the loss recovery of reliable broadcast transmission in wireless networks. Since it was proved that fi nding the optimal set of lost packets for XOR-ing is a complex NP-complete problem, the available time-based retransmission scheme and its enhanced retransmission scheme have exponential computational complexity and thus are not scalable to large networks. In this paper, we present an efficient heuristic scheme based on hypergraph coloring and also its enhanced heuristic scheme to improve the transmission efficiency. Basically, our proposed schemes fi rst create a hypergraph according to the packet-loss matrix. Then our schemes solve the problem of generating XORed packets by coloring the edges of hypergraph. Extensive simulation results demonstrate that, the heuristic scheme based on hypergraph coloring and its enhanced scheme can achieve almost the same transmission efficiency as the available ones, but have much lower computational complexity, which is very important for the wireless devices without high computation capacity.Wang Jing Chi Kaikai Wang Xinmei 2010China Communications2010,7,2:4
19Mechanism underlying the retarded nuclear translocation of androgen receptor splice variants显示文摘As shown in our previous study, two alternatively spliced androgen receptor(AR) variants, which are exclusively expressed in the granulosa cells of patients with polycystic ovary syndrome, exhibit retarded nuclear translocation compared with wild-type AR. However, researchers have not yet determined whether these abnormalities correlate with heat shock protein 90(HSP90)and importin α(the former is a generally accepted co-chaperone of AR, and the latter is a component of classical nuclear import complexes). Here, these two variants were mainly retained in cytoplasm with HSP90 and importin α in the presence of dihydrotestosterone(DHT), and their levels in nucleus were significantly reduced, according to the immunofluorescence staining. The binding affinity of two AR variants for importin α was consistently decreased, while it was increased in WT-AR following DHT stimulation, leading to reduced nuclear import, particularly for the insertion-AR(Ins-AR). However, the binding affinities of two AR variants for HSP90 were increased in the absence of DHT compared with WT-AR, which functioned to maintain spatial structural stability, particularly for the deletion-AR(Del-AR). Therefore, the retarded nuclear translocation of two AR variants is associated with HSP90 and importin α, and the abnormal binding affinities for them play critical roles in this process.Ye Liu Yinyu Wang Fangfang Wang Jiexue Pan Jingjing Xu Jingyi Li Chengliang Zhou Guolian Ding Yanting Wu Xinmei Liu Jianzhong Sheng Hefeng Huang 2019Science China(Life Sciences)2019,62,2:4
20DESIGN OF QUASI-CYCLIC LDPC CODES BASED ON EUCLIDEAN GEOMETRIES显示文摘A new method for constructing Quasi-Cyclic (QC) Low-Density Parity-Check (LDPC) codes based on Euclidean Geometry (EG) is presented. The proposed method results in a class of QC-LDPC codes with girth of at least 6 and the designed codes perform very close to the Shannon limit with iterative decoding. Simulations show that the designed QC-LDPC codes have almost the same performance with the existing EG-LDPC codes.Liu Yuanhua Niu Xinliang Wang Xinmei Fan Jiulun 2010Journal of Electronics(China)2010,27,3:4
