| 2 | Evaluating the Phylogenetic Position of Chinese Tree Shrew(Tupaia belangeri chinensis) Based on Complete Mitochondrial Genome:Implication for Using Tree Shrew as an Alternative Experimental Animal to Primates in Biomedical Research显示文摘Tree shrew(Tupaia belangeri) is currently placed in Order Scandentia and has a wide distribution in Southeast Asia and Southwest China.Due to its unique characteristics,such as small body size,high brain-to-body mass ratio,short reproductive cycle and life span,and low-cost of maintenance,tree shrew has been proposed to be an alternative experimental animal to primates in biomedical research.However,there are some debates regarding the exact phylogenetic affinity of tree shrew to primates.In this study,we determined the mtDNA entire genomes of three Chinese tree shrews(T.belangeri chinensis) and one Malayan flying lemur(Galeopterus variegatus).Combined with the published data for species in Euarchonta,we intended to discern the phylogenetic relationship among representative species of Dermoptera,Scandentia and Primates.The mtDNA genomes of Chinese tree shrews and Malayan flying lemur shared similar gene organization and structure with those of other mammals.Phylogenetic analysis based on 12 concatenated mitochondrial proteinencoding genes revealed a closer relationship between species of Scandentia and Glires,whereas species of Dermoptera were clustered with Primates.This pattern was consistent with previously reported phylogeny based on mtDNA data,but differed from the one reconstructed on the basis of nuclear genes.Our result suggested that the matrilineal affinity of tree shrew to primates may not be as close as we had thought.The ongoing project for sequencing the entire genome of Chinese tree shrew will provide more information to clarify this important issue. | Ling Xu Shi-Yi Chen Wen-Hui Nie Xue-Long Jiang Yong-Gang Yao | 2012 | Journal of Genetics and Genomics2012，39，3： | 25 |

| 6 | Study on interaction between microtubule associated protein tau and prion protein显示文摘Microtubule-associated protein tau is considered to play roles in many neurodegenera-tive diseases including some transmissible spongiform encephalopathies.To address the possible molecular linkage of prion protein(PrP) and tau,a GST-fusion segment of human tau covering the three-repeat region and various PrP segments was used in the tests of GST pull-down and immuno-precipitation.We found tau protein interacted with various style prion proteins such as native prion protein(PrPC) or protease-resistant isoform(PrPSc) .Co-localization signals of tau and PrP were found in the CHO cell tranfected with both PrP and tau gene.The domain of interaction with tau was located at N-terminal of PrP(residues 23 to 91) .The evidence of molecular interactions between PrP and tau protein highlights a potential role of tau in the biological function of PrP and the pathogenesis of TSEs. | HAN Jun1,ZHANG Jin1,2,YAO Hailan1,3,WANG Xiaofan1,LI Feng1,CHEN Lan1,4,GAO Chen1,GAO Jianmei1,NIE Kai1,ZHOU Wei1 & DONG Xiaoping11.State Key Laboratory for Infectious Diseases Prevention and Control,National Institute for Viral Disease Control and Pre-vention,Chinese Center for Disease Control and Prevention,Beijing 100052,China 2.School of Medicine,Xi’an Jiao-Tong University,Xi’an 710061,China 3.Tong-Ji Medical College,Hua-Zhong University of Science and Technology,Wuhan 430030,China 4.National Laboratory of Medical Molecular Biology,Institute of Basic Medical Science,Chinese Academy of Medical Sciences and Peking Union Medical College,Beijing 100005,China | 2006 | Science China(Life Sciences)2006，49，5： | 10 |
| 7 | Land cover mapping using time series HJ-1 / CCD data显示文摘It is very difficult to have remote sensing data with both high spatial resolution and high temporal frequency; thus, two categories of land-use mapping methodology have been developed separately for coarser resolution and finer resolution data. The first category uses time series of data to retrieve the variation of land surface for classification, which are usually used for coarser resolution data with high temporal frequency. The second category uses fine spatial resolution data to classify different land surface. With the launch of Chinese satellite constellation HJ-1in 2008, four 30 m spatial resolution CCDs with about 360 km coverage for each one onboard two satellites made a revisit period of two days, which brought a new type of data with both high spatial resolution and high temporal frequency. Therefore, by taking the spatiotemporal advantage of HJ-1/CCD data we propose a new method for finer resolution land cover mapping using the time series HJ-1/CCD data, which can greatly improve the land cover mapping accuracy. In our two study areas, the very high resolution remote sensing data within Google Earth are used to validate the land cover mapping results, which shows a very high mapping accuracy of 95.76% and 83.78% and a high Kappa coefficient of 0.9423 and 0.8165 in the Dahuofang area of Liaoning Province and the Heiquan area of Gansu Province respectively. | ZHONG Bo MA Peng NIE AiHua YANG AiXia YAO YanJuan Lü WenBo ZHANG Hang LIU QinHuo | 2014 | Science China Earth Sciences2014，57，8： | 9 |
| 8 | Fractionated and Confined Crystallization of Polybutene-1 in Immiscible Polypropylene/Polybutene-1 Blends显示文摘In this work,the crystallization of immiscible polypropylene(PP)/polybutene-1(PB)blends,in particular the effect of crystal morphology of PP(HTC,high Tm component)on the subsequent crystallization behavior of PB(LTC,low Tm component)was studied.Herein,we firstly indicated that PP/PB blends were not completely compatible but characterized as the LCST-like phase diagram above the melting temperature of PP.Crystallization of PP at different crystallization temperatures brought about different PP crystal morphologies and PB was segregated and confined at different locations.Much larger-sized domain of PB component appeared in PP spherulites resulting from the effects of non-negligible phase separation and the slower PP crystallization rate as PP crystallized at high temperature.As temperature continued to fall below Tm of PB,the fractionated and confined crystallization of PB occurred in the framework of PP spherulites,reflected by the decreased crystallization temperature(Tc)of PB and the formation of form I′beside form II.Notably,if PP previously crystallized at high Tc,fractionated crystallization of PB became predominant and confined crystallization of PB became weak due to the much wider droplet-size distribution of PB domains. | Yao Xu Chen-Guang Liu Hua-Rong Nie Ai-Hua He | 2018 | Chinese Journal of Polymer Science2018，36，7： | 7 |

| 10 | Spider web-like carbonized bacterial cellulose/MoSe_(2) nanocomposite with enhanced microwave attenuation performance and tunable absorption bands显示文摘It is essential to manufacture microwave absorbers with strong absorption as well as tunable absorption bands at a low filler content.However,it remains challenging for pure biomass material to reach this goal without loading other components.MoSe_(2),as a transition metal chalcogenide with semiconductor properties,has emerged as a potential microwave absorber filler.Herein,bacterial cellulose(BC)-derived carbon nanofibers/MoSe_(2) nanocomposite was fabricated and phosphoric acid was used to dope phosphorus in BC,in which MoSe_(2) microspheres were dropped on the BC network like a dew-covered spider web.This unique network structure enhances conductive loss and multiple reflections of the incident wave.The collocation of BC and MoSe_(2) is helpful to impedance match and introduces interfacial/dipolar polarization loss;moreover,the P-doping of BC helps to tune the absorption bands.Overall,the optimal reflection loss of undoped one reaches−53.33 dB with only 20 wt.%filler content,whose main absorption peaks focus on X-band.Interestingly,after the P-doping of BC,the main absorption peaks move to Ku-band and the optimal reflection loss gets stronger(−66.84 dB)with the same filler loading.Strong absorption and tunable absorption bands can be realized,and thus wide frequency range is covered.This work is expected to enlighten future exploration of biomass carbon materials on high-performance microwave absorption materials. | Zhengjian Xu Man He Yuming Zhou Shuangxi Nie Yongjuan Wang Yao Huo Yifan Kang Ruili Wang Ran Xu Hao Peng Xi Chen | 2021 | Nano Research2021，14，3： | 6 |
| 11 | Effects of different ingredients of zedoary on gene expression of HSC-T6 cells显示文摘AIM: To investigate the effects of four different ingredients of zedoary (Curcuma aromatica oil, Curcumol,β-elemence, and Curcumin) on the gene expressions of hepatic stellate cells (HSCs), and to explore the molecular mechanism of zedoary against hepatic fibrosis at gene network level.METHODS: We detected the mRNA sequences of 50 liver fibrosis-related genes in GenBank and designed oligonucleotide probes. We synthesized oligonucleotides with PE8909 DNA synthesizing instrument, and carried out oligonucleotide microarray with OGR-04 dropping instrument and aldehyded glass chip. Cultured HSC-T6cells were treated with different concentrations of Colchicine,Curcuma aromatica oil, Curcumol, β-elemence, and Curcumin. According to the experiment of cell toxicity,we took the appropriate concentrations of medicines that resulted in over 50% of cell survival as experiment concentrations. We collected the cells at 1, 6, 12, and 24 h, and extracted total RNA with TRIzol reagent, then labeled cDNAs with Cy3-dUTP and Cy5-dUTP. These labeled cDNAs were hybridized to an oligonucleotide microarray which was washed several times and scanned by scanner GenePix 4000B. Different gene expressions of HSC-T6 cells were analyzed by ImaGene 4.2 software.RESULTS: After HSC-T6 cells were cultured in a medium containing 6.25 μg/mL Colchicine for 12 h, expression of TIMP-1 decreased 2.2-folds. After HSC-T6 cells were cultured in a medium containing 78.125 μg/mL of Curcuma aromatica oil for 24 h, the expression of TIMP-2and IL-6 decreased 2.3- and 2.2-folds, respectively.Moreover, after HSC-T6 cells were cultured in a medium containing 1.5625 μg/mL of Curcumol for 12 h, the expression of TGFβ1 and P450a decreased 2.3- and 2.1-folds, respectively.CONCLUSION: Our results may show the possible molecular mechanism of Curcuma aromatica oil and Curcumol against hepatic fibrosis. | Yuan Jiang Ze-Song Li Fu-Sheng Jiang Xin Deng Cong-Shun Yao Guang Nie | 2005 | World Journal of Gastroenterology2005，11，43： | 5 |

| 15 | Unraveling a genetic roadmap for improved taste in the domesticated apple显示文摘Although taste is an important aspect of fruit quality, an understanding of its genetic control remains elusive in apple and other fruit crops. In this study, we conducted genomic sequence analysis of 497 Malus accessions and revealed erosion of genetic diversity caused by apple breeding and possible independent domestication events of dessert and cider apples. Signatures of selection for fruit acidity and size, but not for fruit sugar content, were detected during the processes of both domestication and improvement. Furthermore, we found that single mutations in major genes affecting fruit taste, including Ma1, MdTDT, and MdSOT2, dramatically decrease malate, citrate, and sorbitol accumulation, respectively, and correspond to important domestication events. Interestingly, Ma1 was identified to have pleiotropic effects on both organic acid content and sugar:acid ratio, suggesting that it plays a vital role in determining fruit taste. Fruit taste is unlikely to have been negatively affected by linkage drag associated with selection for larger fruit that resulted from the pyramiding of multiple genes with minor effects on fruit size. Collectively, our study provides new insights into the genetic basis of fruit quality and its evolutionary roadmap during apple domestication, pinpointing several candidate genes for genetic manipulation of fruit taste in apple. | Liao Liao Weihan Zhang Bo Zhang Ting Fang Xiao-Fei Wang Yarning Cai Collins Ogutu Lei Gao Gang Chen Xiaoqing Nie Jinsheng Xu Quanyan Zhang Yiran Ren Jianqiang Yu Chukun Wang Cecilia H.Deng Baiquan Ma Beibei Zheng Chun-Xiang You Da-Gang Hu Richard Espley Kui Lin-Wang Jia-Long Yao Andrew C.Allan Awais Khan Schuyler S.Korban Zhangjun Fei Ray Ming Yu-Jin Hao Li Li Yuepeng Han | 2021 | Molecular Plant2021，14，9： | 5 |
| 16 | All VN-graphene architecture derived self-powered wearable sensors for ultrasensitive health monitoring显示文摘The booming of wearable electronics has nourished the progress on developing multifunctional energy storage systems with versatile flexibility, which enable the continuous and steady power supply even under various deformed states. In this sense, the synergy of flexible energy and electronic devices to construct integrative wearable microsystems is meaningful but remains quite challenging by far. Herein, we devise an innovative supercapacitor/sensor integrative wearable device that is based upon our designed vanadium nitride-graphene (VN-G) architectures. Flexible quasi-solid-state VN-G supercapacitor with ultralight and binder-free features deliver a specific capacitance of^53 F·g^-1 with good cycle stability. On the other hand, VN-G derived pressure sensors fabricated throughout a spray-printing process also manifest favorably high sensitivity (40 kPa^-1 at the range of 2-10 kPa), fast response time (~130 ms), perfect skin conformability, and outstanding stability under static and dynamic pressure conditions. In tum, their complementary unity into a self-powered wearable sensor enables the precise detecti on of physiological motions ranging from pulse rate to phonetic recognition, holding promise for in-practical health monitoring applications. | Lianghao Yu Yuyang Yi Ting Yao Yingze Song Yiran Chen Qiucheng Li Zhou Xia Nan Wei Zhengnan Tian Baoqing Nie Li Zhang Zhongfan Liu Jingyu Sun | 2019 | Nano Research2019，12，2： | 4 |
| 17 | Genomic and genic sequence variation in synthetic hexaploid wheat (AABBDD) as compared to their parental species显示文摘In order to understand the genomic changes during the evolution of hexaploid wheat, two sets of synthetic hexaploid wheat from hybridization between maternal tetraploid wheat (AABB) and paternal diploid goat grass (DD) were used for DNA-AFLP and single strand conformation polymorphism (SSCP) analysis to determine the genomic and genic variation in the synthetic hexaploid wheat. Results indicated that more DNA sequences from paternal diploid species were eliminated in the synthetic hexaploid wheat than from maternal tetraploid wheat, suggesting that genome from parental species of lower ploidity tends to be eliminated preferentially. However, sequence variation detected by SSCP procedure was much lower than those detected by DNA-AFLP, which indicated that much less variation in the genic regions occurred in the synthetic hexaploid wheat, and sequence variations detected by DNA-AFLP could be derived mostly from non-coding regions and repetitive sequences. Our results also indicated that sequence variation in 4 genes can be detected in hybrid F1, which suggested that this type of sequence variation could be resulted from distant hybridization. It was interesting to note that 3 out of the 4 genes were mapped and clustered on the long arm of chromosome 2D, which indicated that variation in genic sequences in synthetic hexaploid wheat might not be a randomized process. | Lihong Nie Zongfu Han Lahu Lu Yingyin Yao Qixin Sun Zhongfu Ni | 2008 | Progress in Natural Science:Materials International2008，18，5： | 4 |
| 18 | The direct electrochemistry of glucose oxidase based on the synergic effect of amino acid ionic liquid and carbon nanotubes显示文摘Amino acid ionic liquids(AAILs) have attracted much attention due to their special chemical and physical properties,especially their outstanding biocompatibility and truly green aspect.In this work,a novel electrochemical biosensing platform based on AAILs/carbon nanotubes(CNTs) composite was fabricated.AAILs were used as a novel solvent for glucose oxidase(GOD) and the GOD-AAILs/CNTs/GC electrode was conveniently prepared by immersing the carbon nanotubes(CNTs) modified glassy carbon(GC) electrode into AAILs containing GOD.The direct electrochemistry of GOD on the GOD-AAILs/CNTs/GC electrode has been investigated and a pair of reversible peaks was obtained by cyclic voltammetry.The immobilized glucose oxidase could retain bioactivity and catalyze the reduction of dissolved oxygen.Due to the synergic effect of AAILs and CNTs,the GOD-AAILs/CNTs/GC electrode shows excellent electrocatalytic activity towards glucose with a linear range from 0.05 to 0.8 mM and a detection limit of 5.5 μM(S/N = 3).Furthermore,the biosensor exhibits good stability and ability to exclude the interference of commonly coexisting uric and ascorbic acid.Therefore,AAILs/CNTs composite can be a good candidate biocompatible material for the direct electrochemistry of the redox-active enzyme and the construction of third-generation enzyme sensors. | WANG MengDong DENG ChunYan NIE Zhou XU XiaHong YAO ShouZhuo | 2009 | Science China Chemistry2009，52，11： | 4 |

All complexes have been fully characterized by elemental analyses, single-crystal X-ray diffraction analysis, and IR and multi-nuclear NMR spectroscopy(in the cases of 1, 4 and 5). Study of their catalytic behavior revealed that, in general, all complexes are efficient initiators for the polymerization of rac-lactide(LA) and rac-β-butyrolactone(BBL), except for 3 and 4 in the case of BBL. The influence imposed by lanthanides of different ionic radii and initiating groups of different structures on the activity, controllability, and stereoselectivity of polymerization were systematically studied and compared. Highly heterotactic PLA(Pr up to 0.99) and syndiotactic PHB(Pr ≈ 0.81) with high molecular weight and narrow polydispersity formed and were automatically capped with hydroxyl functionality at both ends. | NIE Kun FENG Tao SONG FengKui ZHANG Yong SUN HongMei YUAN Dan YAO YingMing SHEN Qi | 2014 | Science China Chemistry2014，57，8： | 3 |
