| 2 | Whole 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 | 2018 | International Journal of Oral Science2018，10，4： | 3 |
| 3 | Crystal structure of human Gadd45 reveals an active dimer显示文摘The human Gadd45 protein family plays critical roles in DNA repair,negative growth control,genomic stability,cell cycle checkpoints and apoptosis.Here we report the crystal structure of human Gadd45,revealing a unique dimer formed via a bundle of four parallel helices,involving the most conserved residues among the Gadd45 isoforms.Mutational analysis of human Gadd45 identified a conserved,highly acidic patch in the central region of the dimer for interaction with the proliferating cell nuclear antigen(PCNA),p21 and cdc2,suggesting that the parallel dimer is the active form for the interaction.Cellular assays indicate that:(1)dimerization of Gadd45 is necessary for apoptosis as well as growth inhibition,and that cell growth inhibition is caused by both cell cycle arrest and apoptosis;(2)a conserved and highly acidic patch on the dimer surface,including the important residues Glu87 and Asp89,is a putative interface for binding proteins related to the cell cycle,DNA repair and apoptosis.These results reveal the mechanism of self-association by Gadd45 proteins and the importance of this self-association for their biological function. | Wenzheng Zhang Sheng Fu Xuefeng Liu Xuelian Zhao Wenchi Zhang Wei Peng Congying Wu Yuanyuan Li Xuemei Li Mark Bartlam Zong-Hao Zeng Qimin Zhan Zihe Rao | 2011 | Protein & Cell2011，2，10： | 1 |

| 5 | Enhanced polysulfide redox kinetics by niobium oxynitrides via insitu adsorptive and catalytic effect in wide temperature range显示文摘The development of Li-S batteries(LSBs)is hindered by the low utilization of S species and sluggish redox reaction kinetics.Polar metal oxides always possess high adsorption to polar S species,while conductive metal nitrides show fast electron transport and ensure fast redox reaction of S species.The combination merits of metal oxides and metal nitrides in one provide an effective strategy to improve the electrochemical performance of LSBs.In this work,defect design of niobium oxynitrides highly dispersed on graphene(NbON-G)is evaluated as effective trapper and catalyst for S species.Owning to the effective structural merits including enriched active sites,alleviated volume variation,defect modulated electronic property,and in-situ chemisorption and catalytic conversion of soluble lithium polysulfides(LiPSs),the LSBs with NbON-G modified separator show remarkably enhanced performance compared to NbN-G and Nb_(2)O_(5)-G.Surprisingly,even at low temperature of−40°C,the LSBs with NbON-G can operate for 1,000 cycles with 0.04%capacity decay per cycle(Rate:2 C). | Benben Wei Chaoqun Shang Qiao Cu Le Hu Xuelian Fu Guofu Zhou Xin Wang | 2022 | Nano Research2022，15，7： | 0 |

| 7 | Cooperative Content Caching and Delivery in Vehicular Networks: A Deep Neural Network Approach显示文摘The growing demand for low delay vehicular content has put tremendous strain on the backbone network.As a promising alternative,cooperative content caching among different cache nodes can reduce content access delay.However,heterogeneous cache nodes have different communication modes and limited caching capacities.In addition,the high mobility of vehicles renders the more complicated caching environment.Therefore,performing efficient cooperative caching becomes a key issue.In this paper,we propose a cross-tier cooperative caching architecture for all contents,which allows the distributed cache nodes to cooperate.Then,we devise the communication link and content caching model to facilitate timely content delivery.Aiming at minimizing transmission delay and cache cost,an optimization problem is formulated.Furthermore,we use a multi-agent deep reinforcement learning(MADRL)approach to model the decision-making process for caching among heterogeneous cache nodes,where each agent interacts with the environment collectively,receives observations yet a common reward,and learns its own optimal policy.Extensive simulations validate that the MADRL approach can enhance hit ratio while reducing transmission delay and cache cost. | Xuelian Cai Jing Zheng Yuchuan Fu Yao Zhang Weigang Wu | 2023 | China Communications2023，20，3： | 0 |
| 8 | Geochronology,Geochemistry and Petrogenesis of the Bangbule Quartz Porphyry:Implications for Metallogenesis显示文摘The Bangbule skarn lead-zinc(Pb-Zn)deposit(>1 Mt Zn+Pb)is located in the western Nyainqentanglha polymetallic metallogenetic belt,central Tibet.Lenticular orebodies are all hosted in skarn and developed in the contact zone between the quartz porphyry and carbonate strata of the mid Paleozoic Middle to Upper Chaguoluoma Formation as well as in carbonate and sandstone beds of the Upper Paleozoic Laga Formation.As a newly discovered skarn deposit,the geological background and metallogenesis of this deposit remain poorly understood.Detailed petrological,geochemical and geochronological data of the ore-related quartz porphyry,helps constrain the mineralization age and contributes to discussion on the ore genesis of the Bangbule deposit.Both endoskarn and exoskarn are identified in the Bangbule deposit.From quartz porphyry to carbonate formation,the exoskarn is zoned from proximal garnet skarn to distal pyroxene skarn.Zircon U-Pb dating results show that the quartz porphyry formed at 73.9±0.8 Ma.Geochemical analysis results show that the quartz porphyry has high contents of SiO_(2)(71.40–74.94 wt%)and K_(2)O+Na_(2)O(3.76–8.46 wt%)with A/CNK values of 0.69 to 1.06.Besides,the quartz porphyry is enriched in large ion lithophile elements(LILEs)and light rare earth elements(LREEs)and have lowεNd(t)(from-8.25 to-8.19)and high initial(^(87)Sr/^(86)Sr)i values(0.713611–0.714478).Major,trace elements and whole-rock F concentration analysis results from the endoskarn samples show higher TFe_(2)O_(3),MgO,CaO,Pb+Zn,W,Sn,Mo and F etc.,and lower alkalis(K_(2)O,Na_(2)O,Sr and Ba)than those of fresh quartz porphyry,indicating that the early ore-forming fluids were an Ca-Fe-F-enriched fluid.Massive ore in the proximal skarn might be related to the high F content in the magma,which lowered the solidus temperature of the quartz porphyry magma and caused a lower temperature of the ore-forming fluids,as well as facilitating the precipitation of sphalerite and galena.Based on the geochemical characteristics presented in this study,we propose that the ore-related quartz porphyry was formed by partial melting of crust materials with some juvenile crustal component input.The partial melting of the middle-upper crust after the initial enrichment of lead and zinc elements are important for the formation of Pb-Zn deposits.The case study of the Bangbule deposit has proven that there is still a crust-derived magmatic source region in the western segment of the central Lhasa terrane.Therefore,there is still great potential for Pb-Zn mineralization and Pb-Zn exploration. | HE Chuankai WANG Yong WANG Haiyong TANG Juxing YAN Penggang WANG Yongqiang FU Xuelian FENG Yipeng | 2023 | Acta Geologica Sinica(English Edition)2023，97，3： | 0 |
| 9 | Molecular genetic analysis of Dongzhou-period ancient human of Helingeer in Inner Mongolia,China显示文摘The mtDNA hypervariable region I(HVR-I)of 10 ancient individuals from Dongzhou-period ancient human populations in Helingeer county of Inner Mongolia were amplified and sequenced to investigate the genetic structure.The relationships between the ancient population and related extant populations,as well as its possible origin at the molecular level,were also studied.Moreover,phylogenetic analysis and multi-dimensional scaling analysis were also performed based on the mtDNA data of the ancient population in Helingeer and the related Eurasian population.The results showed that the ancient population in Helingeer were closer to the northern Asian populations than to the other compared populations in matrilineal lineage.Combining the research results of archaeology and anthropology as well as molecular biology,we inferred that they were nomads who migrated from Mongolia plateau and cis-Baikal region to Helingeer in Inner Mongolia,China. | Yuqin FU Chengzhi XIE Han ZHAO Xuelian XU Yinqiu CUI Quanchao ZHANG Hui ZHOU Hong ZHU | 2008 | Frontiers in Biology2008，3，1： | 0 |
| 10 | Decorative Wood Fiber/High-Density Polyethylene Composite with Canvas or Polyester Fabric显示文摘Wood-plastic composite is an environmentally friendly material,due to its use of recycled thermoplastics and plant fibers.However,its surface lacks attractive aesthetic qualities.In this paper,a method of decorating wood fiber/high-density polyethylene(WF/HDPE)without adding adhesive was explored.Canvas or polyester fabrics were selected as the surface decoration materials.The influence of hot-pressing temperature and WF/HDPE ratio on the adhesion was studied.The surface bonding strength,water resistance,and surface color were evaluated,and observation within the infrared spectrum and under scanning electron microscopy was used to analyze the bonding process.The results showed that the fabric and WF/HDPE substrate could be closely laminated together depending on the HDPE layer accumulated on the WF/HDPE surface.The molten HDPE matrix penetrates canvas more easily than polyester fabric,and the canvasveneered composite shows a greater bonding strength than does the polyester fabric-veneered composite.A higher proportion of the thermoplastic component in the substrate improved the bonding.When the hot-pressing temperature exceeded 160°C,the fabric-veneered WF/HDPE panels had greater water resistance,although the canvas fabric changed more obviously in terms of fiber shape and color,compared with the polyester fabric.For the canvas fabric,140°C–160°C was a suitable hot-pressing temperature,whereas 160°C–180°C was more suitable for polyester fabric.The proportion of the thermoplastic component in the composite should be not less than 30%to achieve adequate bonding strength. | Jialin Lv Rao Fu Yinan Liu Xuelian Zhou Weihong Wang Pengbo Xie Tingwei Hu | 2020 | Journal of Renewable Materials2020，8，8： | 0 |
| 11 | Thermal History of the Naruo Porphyry Deposit in the Duolong Ore District,Western Tibet:Evidence from U-Pb,^(40)Ar/^(39)Ar and(U-Th)/He Thermochronology显示文摘The Naruo porphyry copper deposit containing more than 2 Mt of copper is located in the Duolong ore district in the west of the Bangongco–Nujiang belt in central Tibet.New zircon U-Pb,biotite^(40)Ar/^(39)Ar,zircon(U-Th)/He ages,published age data together with thermal modeling were presented in this paper to investigate the thermal history of Naruo deposit.Thermal modeling reveals a prolonged magmatic-hydrothermal evolution firstly cooling from~700℃to~350℃at 120 Ma,then cooling to 230℃at 106 Ma and maintaining at 200℃from 106 to 90 Ma which is attributed to multiple magmatic events and thermal effect of strike-slip fault.Affected by thrust nappe structure,the sample was consistent with 120℃from 70 to 63 Ma.The Naruo deposit started to experience exhumation at a rate of~0.07 km/Myr since 60 Ma which is related to India-Asia collision.The prolonged magmatic-hydrothermal evolution process might have important influence on the Naruo deposit.The ore-related intrusions preserved in the foot walls of strike-slip fault and thrust nappe structure are the objects of future exploration in the Duolong ore district. | YANG Huanhuan FANG Xiang SONG Yang LIN Bin LI Yanbo WANG Qin LIU Zhibo HE Long ZHANG Qi FU Xuelian | 2022 | Acta Geologica Sinica(English Edition)2022，96，6： | 0 |
