| 2 | Malvastrum yellow vein virus,a new Begomovirus species associated with satellite DNA molecule显示文摘Virus isolate Y47 was obtained from Malvastrum coromandelianum showing yellow vein symptom in Honghe, Yunnan Province. The complete nucleotide sequence of DNA-A was determined, it contains 2731 nucleotides, having typical genomic organization of a begomovirus, encoding 6 ORFs with 2 ORFs [AV1(CP) and AV2] in virion- sense DNA and 4 ORFs (AC1—AC4) in complementary- sense DNA. Comparisons show that the total DNA-A of Y47 has the highest sequence identity (77%) with that of Okra yellow vein mosaic virus-[201] (AJ002451), while less than 76% identities are found when compared with other begomoviruses. The molecular data show that virus isolate Y47 is a distinct begomovirus species, for which the name Malvastrum yellow vein virus is proposed. Satellite DNA molecule (Y47b) was found to be associated with Y47 using the primers (beta01 and beta02) specific for DNAb. Y47b consists of 1348 nucleotides, with a functional ORF (C1) in complementary-sense DNA. Y47b has 62%—67% sequence identity with DNAb molecule associated with Cotton leaf curl Multan virus or Cotton leaf curl Rajasthan virus, while lower than 46% sequence identities are found when compared with other reported DNAb molecules. Relationship dendrograms show that DNAb molecules are co-evolved with their help begomoviruses. | ZHOUXuepinq XIEYan PENGYan ZHANGZhongkai | 2003 | Chinese Science Bulletin2003，48，20： | 11 |
| 3 | Single-Atom Catalysts for Electrochemical Hydrogen Evolution Reaction: Recent Advances and Future Perspectives显示文摘Hydrogen,a renewable and outstanding energy carrier with zero carbon dioxide emission,is regarded as the best alternative to fossil fuels.The most preferred route to large-scale production of hydrogen is by water electrolysis from the intermittent sources(e.g.,wind,solar,hydro,and tidal energy).However,the efficiency of water electrolysis is very much dependent on the activity of electrocatalysts.Thus,designing high-effective,stable,and cheap materials for hydrogen evolution reaction(HER)could have a substantial impact on renewable energy technologies.Recently,single-atom catalysts(SACs)have emerged as a new frontier in catalysis science,because SACs have maximum atom-utilization efficiency and excellent catalytic reaction activity.Various synthesis methods and analytical techniques have been adopted to prepare and characterize these SACs.In this review,we discuss recent progress on SACs synthesis,characterization methods,and their catalytic applications.Particularly,we highlight their unique electrochemical characteristics toward HER.Finally,the current key challenges in SACs for HER are pointed out and some potential directions are proposed as well. | Zonghua Pu Ibrahim Saana Amiinu Ruilin Cheng Pengyan Wang Chengtian Zhang Shichun Mu Weiyue Zhao Fengmei Su Gaixia Zhang Shijun Liao Shuhui Sun | 2020 | Nano-Micro Letters2020，12，2： | 10 |
| 4 | Transdifferentiation of tumor infiltrating innate lymphoid cells during progression of colorectal cancer显示文摘Innate lymphoid cells(ILCs)reside in mucosal surfaces to potentiate immune responses,sustain mucosal integrity and maintain tissue homeostasis.However,how tumor infiltrating ILCs modulate tumor development and progression is unclear.Here we profiled tumor infiltrating ILCs during colorectal cancer(CRC)progression by single-cell RNA sequencing.We identified six clusters of tumor infiltrating ILCs with unique features.ILC1s expressed inhibitory receptors and underwent inhibitory functional conversion at the late stage of CRC.ILC2s were classified into three subsets(called ILC2-A,-B,-C),of which ILC2-C subset could facilitate tumor progression.HS3ST1 and PD1 were highly expressed in ILC2s of late stage CRC tumors and deficiency of HS3ST1 or PD1 in ILC2s suppressed tumor growth.Moreover,ILC3s transdifferentiated into ILCregs during CRC progression and ILCregs promoted tumor growth.Of note,TGF-βsignaling initiated the conversion of ILC3s to ILCregs and blockade of TGF-βsignaling could disrupt the ILCreg transdifferentiation and inhibited tumor growth.Thus,intervention of ILC conversions might be a potential strategy for CRC immunotherapy. | Shuo Wang Yuan Qu Pengyan Xia Yi Chen Xiaoxiao Zhu Jing Zhang Guan Wang Yong Tian Jianming Ying Zusen Fan | 2020 | Cell Research2020，30，7： | 9 |
| 5 | Outcome of multimodal MRI-guided intravenous thrombolysis in patients with stroke with unknown time of onset显示文摘Objective Intravenous tissue plasminogen activator(tPA)is the standard therapy for patients with acute ischaemic stroke(AIS)within 4.5 hours of onset.Recent trials have expanded the endovascular treatment window to 24 hours.We investigated the efficacy and safety of using multimodal MRI to guide intravenous tPA treatment for patients with AIS of unknown time of onset(UTO).Methods Data on patients with AIS with UTO and within 4.5 hours of onset were reviewed.Data elements collected and analysed included:demographics,National Institutes of Health Stroke Scale(NIHSS)score at baseline and 2 hours,24 hours,7 days after thrombolysis and before discharge,the modified Rankin Scale(mRS)score at 3 months after discharge,imaging findings and any adverse event.results Forty-two patients with UTO and 62 in control group treated within 4.5 hours of onset were treated with intravenous tPA.The NIHSS scores after thrombolysis and/or before discharge in UTO group were significantly improved compared with the baseline(p<0.05).Between the two groups,no significant differences in NIHSS score were observed(p>0.05).Utilising the non-inferiority test,to compare mRS scores(0-2)at 3 months between the two groups,the difference was 5.2%(92%CI,OR 0.196).Patients in the UTO group had mRS scores of 0-2,which were non-inferior to the control group.Their incidence of adverse events was similar.Conclusions Utilising multimodal MRI to guide intravenous only thrombolysis for patients with AIS with UTO was safe and effective.In those patients with AIS between 6 and 24 hours of time of onset but without large arterial occlusion,intravenous thrombolysis could be considered an option. | Jie Zhao Hongmei Zhao Runtao Li Jiangtao Li Chang Liu Juan Lv Yanan Li Wei Liu Dongpu Ma Huaihai Hao Xinguang Xiao Junzhong Liu Yongfeng Yin Rongli Liu Qiaoyan Yu Yingjie Wei Pengyan Li Yue Wang Runqing Wang | 2019 | Stroke & Vascular Neurology2019，4，1： | 8 |
| 6 | Photodegradation mechanism of deltamethrin and fenvalerate显示文摘To understand the degradation and environmental fate of pyrethroids,the process of their photodegradation under simulated natural conditions was investigated.The results showed that the degradation process follows first-order kinetics.The degradation intermediates were identified with gas chromatography-mass spectrometry.A plausible mechanism was discussed to explain the process.Several influences on degradation process were investigated and reported such as the effects of initial concentration of pyrethroids,total time of light irradiation,solvents,and light source,as well as the effect of a few substances that exist in the environment.This study could be a good reference for the degradation of pyrethroids in practical circumstances. | Pengyan Liu Yujie Liu Qingxue Liu Jinwei Liu | 2010 | Journal of Environmental Sciences2010，22，7： | 8 |
| 7 | RNF2 is recruited by WASH to ubiquitinate AMBRA1 leading to downregulation of autophagy显示文摘洗(Wiskott-Aldrich 症候群蛋白质(黄蜂) 和疤相当或相同的事物) 被识别在经由 Arp2/3 激活排序的 endosomal 工作。我们以前表明了那洗在有 AMBRA1 的 BECN1-PIK3C3 建筑群是 BECN1 和现在的新 interactor。AMBRA1-DDB1-CUL4A 建筑群是为 BECN1 的连接 K63 的 ubiquitination 的 E3 ligase,它为导致饥饿的 autophagy 被要求。洗由 BECN1 ubiquitination 的抑制压制 autophagy。然而, AMBRA1 怎么在 autophagy 期间被调整,留下逃犯。这里,我们发现 RNF2 与 AMBRA1 联系经由 K48 连接充当 E3 ligase 到 ubiquitinate AMBRA1。RNF2 调停在离氨酸 45 点的 AMBRA1 的 ubiquitination。尤其是, RNF2 缺乏提高 autophagy 正式就职。在 autophagy 正式就职之上, RNF2 加强 AMBRA1 降级在的帮助下洗。洗缺乏与 AMBRA1 损害 RNF2 的协会阻碍 AMBRA1 降级。我们的调查结果揭示 autophagy 的规定的另一新奇的层通过为导致 autophagy 的 downregulation 的 AMBRA1 降级洗 RNF2 的招募。 | Pengyan Xia Shuo Wang Guanling Huang Ying Du Pingping Zhu Man Li Zusen Fan | 2014 | Cell Research2014，24，8： | 7 |
| 8 | Effect of microstructure of Au80Sn20 solder on the thermal resistance TO56 packaged GaN-based laser diodes显示文摘Au80Sn20 alloy is a widely used solder for laser diode packaging.In this paper,the thermal resistance of Ga N-based blue laser diodes packaged in TO56 cans were measured by the forward voltage method.The microstructures of Au80Sn20 solder were then investigated to understand the reason for the difference in thermal resistance.It was found that the microstructure with a higher content of Au-rich phase in the center of the solder and a lower content of(Au,Ni)Sn phase at the interface of the solder/heat sink resulted in lower thermal resistance.This is attributed to the lower thermal resistance of Au-rich phase and higher thermal resistance of(Au,Ni)Sn phase. | Hao Lin Deyao Li Liqun Zhang Pengyan Wen Shuming Zhang Jianping Liu Hui Yang | 2020 | Journal of Semiconductors2020，41，10： | 4 |
| 9 | Accelerated generation of oligodendrocyte progenitor cells from human induced pluripotent stem cells by forced expression of Sox10 and Olig2显示文摘Oligodendrocyte progenitor cells(OPCs) hold great promise for treatment of dysmyelinating disorders, such as multiple sclerosis and cerebral palsy. Recent studies on generation of human OPCs mainly use human embryonic stem cells(hESCs) or neural stem cells(NSCs) as starter cell sources for the differentiation process. However, NSCs are restricted in availability and the present method for generation of oligodendrocytes(OLs) from ESCs often requires a lengthy period of time. Here, we demonstrated a protocol to efficiently derive OPCs from human induced pluripotent stem cells(hiPSCs) by forced expression of two transcription factors(2TFs), Sox10 and Olig2. With this method, PDGFRα+ OPCs can be obtained in 14 days and O4^+ OPCs in 56 days.Furthermore, OPCs may be able to differentiate to mature OLs that could ensheath axons when co-cultured with rat cortical neurons. The results have implications in the development of autologous cell therapies. | Pengyan Li Mo Li Xihe Tang Shuyan Wang Y.Alex Zhang Zhiguo Chen | 2016 | Science China(Life Sciences)2016，59，11： | 4 |
| 10 | A flexible thermoelectric device based on a Bi_(2)Te_(3)-carbon nanotube hybrid显示文摘Thermoelectric(TE)materials and devices have attracted great attention due to their ability to convert waste heat to electrical power and active cooling.However,the conventional bulk TE materials are inorganic semiconductors with inherent brittleness and rigidity.They cannot closely contact curved heat sources and sinks,which limits their application in modern electronics.It remains a big challenge to fabricate high-performance TE materials and devices with good flexibility.Here,we report a flexible TE device comprised of a single wall carbon nanotube(SWCNT)network and(0001)-textured Bi_(2)Te_(3)nanocrystals prepared by a magnetron sputtering technique.The unique Bi_(2)Te_(3)-SWCNT hybrid structure has a TE figure of merit(ZT)value of^0.23 at^330 K.A prototype TE device made of this hybrid gives a maximum output power density of^0.93 m W cm^(-2)under a temperature difference of 25 K at ambient temperature and shows good flexibility under bending.Our results open up a new way to the development of flexible TEs and their application in self-powered portable devices. | Ying Li Jixiang Qiao Yang Zhao Qing Lan Pengyan Mao Jianhang Qiu Kaiping Tai Chang Liu Huiming Cheng | 2020 | Journal of Materials Science & Technology2020，58，23： | 3 |
| 11 | Tunable Ru-Ru2P heterostructures with charge redistribution for efficient pH-universal hydrogen evolution显示文摘Designing synergistic heterogeneous catalytic interfaces is the key to developing highly compatible pH-universal electrocatalysts for complex chemical environments.Our theoretical calculation results demonstrate that the Ru-Ru2P heterointerface can not only promote the redistribution of charges,but also reduce the d-band center,and then enhances the adsorption capacity of the key intermediate.However,in situ and facile synthesis of Ru-Ru2P heterostructures is severely limited by thermodynamic obstacles.Herein,we propose a molten salt-assisted catalytic synthesis scheme,and successfully build a series of homologous metallic Ru-Ru2P heterostructure catalysts with different molar ratios of Ru to P under atmospheric pressure and low-temperature(400C).The resultant Ru-Ru2P with rich heterostructures show the Pt-like HER performance in different pH media.Particularly,it is prominent under alkaline conditions(18 mV@10 mA cm^(2)),which outperforms the Pt catalyst(37 mV@10 mA cm^(2)).Furthermore,Ru-Ru2P heterostructures also show certain potential in the electrolysis of seawater to produce hydrogen.This work represents a significant supplement of high-efficiency pH-universal HER catalysts,and provides a new light on interface engineering in energy technology fields and beyond. | Ding Chen Ruohan Yu Ruihu Lu Zonghua Pu Pengyan Wang Jiawei Zhu Pengxia Ji Dulan Wu Jinsong Wu Yan Zhao Zongkui Kou Jun Yu Shichun Mu | 2022 | InfoMat2022，4，5： | 2 |
| 12 | Downregulation of MEIS1 mediated by ELFN1-AS1/EZH2/DNMT3a axis promotes tumorigenesis and oxaliplatin resistance in colorectal cancer显示文摘Oxaliplatin is widely used in the frontline treatment of colorectal cancer(CRC),but an estimated 50%of patients will eventually stop responding to treatment due to acquired resistance.This study revealed that diminished MEIS1 expression was detected in CRC and harmed the survival of CRC patients.MEIS1 impaired CRC cell viabilities and tumor growth in mice and enhanced CRC cell sensitivity to oxaliplatin by preventing DNA damage repair.Mechanistically,oxaliplatin resistance following MEIS1 suppression was critically dependent on enhanced FEN1 expression.Subsequently,we confirmed that EZH2-DNMT3a was assisted by lncRNA ELFN1-AS1 in locating the promoter of MEIS1 to suppress MEIS1 transcription epigenetically.Based on the above,therapeutics targeting the role of MEIS1 in oxaliplatin resistance were developed and our results suggested that the combination of oxaliplatin with either ELFN1-AS1 ASO or EZH2 inhibitor GSK126 could largely suppress tumor growth and reverse oxaliplatin resistance.This study highlights the potential of therapeutics targeting ELFN1-AS1 and EZH2 in cell survival and oxaliplatin resistance,based on their controlling of MEIS1 expression,which deserve further verification as a prospective therapeutic strategy. | Yimin Li Yaqi Gan Jiaxin Liu Juanni Li Zhengwei Zhou Ruotong Tian Ruizheng Sun Jiaqi Liu Qing Xiao Yuanyuan Li Pengyan Lu Yulong Peng Yuqian Peng Guang Shu Gang Yin | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 2 |
| 13 | Electrical Conductivity,Oil Absorption and Electric Heating of Carbon Black-modified Carbon Nanofibers显示文摘Carbon-black-modified carbon nanofibers were prepared by electrospinning,and the effects of the carbon black content and processing temperature on the physical and chemical properties of the resulting composites were investigated.The results showed that the conductivity of carbon-black-modified nanofibers increased with the carbon black content.The addition of carbon black in a 20%mass ratio increased the conductivity of the composite(0.75 S/cm)by 230%compared with the undoped nano-fiber(2.47 S/cm),while the adulteration with 5%CB allowed the preservation of the mechanical properties of the composites.The fabricated carbon-black/carbon-nanocomposite fibers exhibited excellent oil absorption and electrothermal conversion performance.Furthermore,the conductivity and oil absorption capacity increased with increasing carbonization temperature.With a carbonization temperature of 1000℃(5%carbon black),the voltage was 31 V,the current was 0.66 A,and the surface temperature of the composite reached 234.1℃.The overall enhancement in physical properties upon the addition of even low amounts of carbon black makes these composites advantageous for future industrial applications. | HUANG Hedong GUO Zeyu YANG Pengyan CHEN Peng Wu Jie | 2021 | Chemical Research in Chinese Universities2021，37，3： | 2 |
| 14 | Dynamic regulation of innate lymphoid cells in the mucosal immune system显示文摘The mucosal immune system is considered a local immune system,a term that implies regional restriction.Mucosal tissues are continually exposed to a wide range of antigens.The regulation of mucosal immune cells is tightly associated with the progression of mucosal diseases.Innate lymphoid cells(ILCs)are abundant in mucosal barriers and serve as first-line defenses against pathogens.The subtype changes and translocation of ILCs are accompanied by the pathologic processes of mucosal diseases.Here,we review the plasticity and circulation of ILCs in the mucosal immune system under physiological and pathological conditions.We also discuss the signaling pathways involved in dynamic ILC changes and the related targets in mucosal diseases. | Fei Shao Dou Yu Pengyan Xia Shuo Wang | 2021 | Cellular & Molecular Immunology2021，18，6： | 2 |
| 15 | Epitaxially Grown Ru Clusters-Nickel Nitride Heterostructure Advances Water Electrolysis Kinetics in Alkaline and Seawater Media显示文摘The epitaxial heterostructure can be rationally designed based on the in situ growth of two compatible phases with lattice similarity,in which the modulated electronic states and tuned adsorption behaviors are conducive to the enhancement of electrocatalytic activity.Herein,theoretical simulations first disclose the charge transfer trend and reinforced inherent electron conduction around the epitaxial heterointerface between Ru clusters and Ni_(3)N substrate(cRu-Ni_(3)N),thus leading to the optimized adsorption behaviors and reduced activation energy barriers.Subsequently,the defectrich nanosheets with the epitaxially grown cRu-Ni_(3)N heterointerface are successfully constructed.Impressively,by virtue of the superiority of intrinsic activity and reaction kinetics,such unique epitaxial heterostructure exhibits remarkable bifunctional catalytic activity toward electrocatalytic OER(226 mV@20 mA cm^(−2))and HER(32 mV@10 mA cm^(−2))in alkaline media.Furthermore,it also shows great application prospect in alkaline freshwater and seawater splitting,as well as solar-to-hydrogen integrated system.This work could provide beneficial enlightenment for the establishment of advanced electrocatalysts with epitaxial heterointerfaces. | Jiawei Zhu Ruihu Lu Wenjie Shi Lei Gong Ding Chen Pengyan Wang Lei Chen Jinsong Wu Shichun Mu Yan Zhao | 2023 | Energy & Environmental Materials2023，6，2： | 2 |
| 16 | Serial nuclear transfer improves the development of interspecies reconstructed giant panda (Aluropoda melanoleucd) embryos显示文摘Interspecies somatic nuclear transfer (NT) may provide a new approach for preservation of the endangered rare species. Previous interspecies cloning studies have shown that a nucleus from a quiescent somatic cell supports early development of reconstructed embryos in the ooplasm from another species. In this study, we transferred nonqui-escent somatic cells from a giant panda into the perivitelline space of the enucleated rabbit oocytes. After electrofusion (at the rate of 71.6%) and electrical activation, 4.2% of the panda-rabbit reconstructed embryos developed to blastocyst in vitro. For improving the development rate of reconstructed embryos, we used serial NT in this study, i.e. blas-tomeres from reconstructed morulae were transferred into the perivitelline space of the enucleated rabbit oocytes. The fusion rates in the groups of serial I, serial Ⅱ and serial Ⅲ were 79.5%, 84.1% and 78.0%, respectively, having no difference with that of somatic group. And the blastocyst rates in serial NT groups | LI Jinsong CHEN Dayuan HAN Zhiming ZHU Ziyu WEN Duancheng SUN Qingyuan LIU Zhonghua WANG Minkang LIAN Li DU Jun WANG Pengyan ZHANG Hemin | 2002 | Chinese Science Bulletin2002，47，6： | 2 |
