| 1 | Key residues of the receptor binding motif in the spike protein of SARS-CoV-2 that interact with ACE2 and neutralizing antibodies显示文摘Coronavirus disease 2019(COVID-19),caused by the novel human coronavirus SARS-CoV-2,is currently a major threat to public health worldwide.The viral spike protein binds the host receptor angiotensin-converting enzyme 2(ACE2)via the receptor-binding domain(RBD),and thus is believed to be a major target to block viral entry.Both SARS-CoV-2 and SARS-CoV share this mechanism.Here we functionally analyzed the key amino acid residues located within receptor binding motif of RBD that may interact with human ACE2 and available neutralizing antibodies.The in vivo experiments showed that immunization with either the SARS-CoV RBD or SARS-CoV-2 RBD was able to induce strong clade-specific neutralizing antibodies in mice;however,the cross-neutralizing activity was much weaker,indicating that there are distinct antigenic features in the RBDs of the two viruses.This finding was confirmed with the available neutralizing monoclonal antibodies against SARS-CoV or SARS-CoV-2.It is worth noting that a newly developed SARS-CoV-2 human antibody,HA001,was able to neutralize SARS-CoV-2,but failed to recognize SARS-CoV.Moreover,the potential epitope residues of HA001 were identified as A475 and F486 in the SARS-CoV-2 RBD,representing new binding sites for neutralizing antibodies.Overall,our study has revealed the presence of different key epitopes between SARS-CoV and SARSCoV-2,which indicates the necessity to develop new prophylactic vaccine and antibody drugs for specific control of the COVID-19 pandemic although the available agents obtained from the SARS-CoV study are unneglectable. | Chunyan Yi Xiaoyu Sun Jing Ye Longfei Ding Meiqin Liu Zhuo Yang Xiao Lu Yaguang Zhang Liyang Ma Wangpeng Gu Aidong Qu Jianqing Xu Zhengli Shi Zhiyang Ling Bing Sun | 2020 | Cellular & Molecular Immunology2020,17,6: | 13 |
| 2 | A study of morphing aircraft on morphing rules along trajectory显示文摘Morphing aircraft can meet requirements of multi-mission during the whole flight due to changing the aerodynamic shape,so it is necessary to study itsmorphing rules along the trajectory.However,trajectory planning considering morphing variables requires a huge number of expensive CFD computations due to the morphing in view of aerodynamic performance.Under the given missions and trajectory,to alleviate computational cost and improve trajectory-planning efficiency formorphing aircraft,an offline optimizationmethod is proposed based onMulti-Fidelity Kriging(MFK)modeling.The angle of attack,Mach number,sweep angle and axial position of the morphing wing are defined as variables for generating training data for building the MFK models,in which many inviscid aerodynamic solutions are used as low-fidelity data,while the less high-fidelity data are obtained by solving viscous flow.Then the built MFK models of the lift,drag and pressure centre at the different angles of attack andMach numbers are used to predict the aerodynamic performance of the morphing aircraft,which keeps the optimal sweep angle and axial position of the wing during trajectory planning.Hence,themorphing rules can be correspondingly acquired along the trajectory,aswell as keep the aircraftwith the best aerodynamic performance during thewhole task.The trajectory planning of amorphing aircraft was performed with the optimal aerodynamic performance based on the MFK models,built by only using 240 low-fidelity data and 110 high-fidelity data.The results indicate that a complex trajectory can take advantage of morphing rules in keeping good aerodynamic performance,and the proposed method is more efficient than trajectory optimization by reducing 86%of the computing time. | Xiaoyu CHEN Chunna LI Chunlin GONG Liangxian GU Andrea Da RONCH | 2021 | Chinese Journal of Aeronautics2021,34,7: | 8 |
| 3 | Spatial and temporal distribution of Neolithic sites in coastal China:Sea level changes, geomorphic evolution and human adaption显示文摘The East China coastal plain is one of the most important Neolithic culture areas in China, where rich archaeological sites including those producing the earliest domesticated rice are observed. It is also a place where landscape has experienced dramatic evolution during the Holocene when both sea level and climate changed, such that it is an ideal place for studying human-environment interaction. This study investigated over 2000 sites of pre-history and Shang and Zhou Dynasties, with 655 of which being Neolithic ages, by using DEM and GIS methods. The results suggest that the spatial and temporal distribution of Neolithic sites has largely been controlled by landscape evolution(particularly changes in coastal line), which ultimately governed by sea level changes. During early Holocene, Neolithic sites sparsely distributed in the intermountain basins of east Zhejiang Province, far from the influence of ocean. Over the period of 9–7 ka, the coastal plain(including the shelf) was largely submerged,only the feet of low hills to the south and southwest of the study area, and islands protruding the estuary, cradled limited number of settlements with characteristic 'maritime components'. At about 7 ka, sea level rise decelerated prominently, while sediments supply in the drainage remained high value, the combination of which led to land formation and propagation. Vast space during this period facilitated the growth of settlements in both size and number. In the mean time, however, the coastal plain was vulnerable to extreme environmental events such as storms and flooding owning to its geomorphic nature, which exerted great influence on the rise and fall of Neolithic culture. | ZHENG HongBo ZHOU YouSheng YANG Qing HU ZhuJun LING GuangJiu ZHANG JuZhong GU ChunGuang WANG YingYing CAO YeTing HUANG XianRong CHENG Yue ZHANG XiaoYu WU WenXiang | 2018 | Science China Earth Sciences2018,61,2: | 7 |
| 4 | Long-term anodal block stimulation at sacral anterior roots promoted recovery of neurogenic bladder function in a rabbit model of complete spinal cord injury显示文摘A complete spinal cord injury model was established in experimental rabbits using the spinal cord clip compression method.Urodynamic examination was performed 2 weeks later to determine neurogenic bladder status.The rabbits were treated with anodal block stimulation at sacral anterior roots for 4 weeks.Electrical stimulation of sacral anterior roots improved urodynamic parameters of neurogenic bladder in rabbit models of complete spinal cord injury,effectively promoted urinary function,and relieved urinary retention.Immunohistochemistry results showed that a balance was achieved among expression of muscarinic receptor subunits M2,M3,ATP-gated ion channel P2X3 receptors,and β2-adrenergic receptor,and nerve growth factor expression decreased.These results suggested that long-term sacral anterior root stimulation of anodal block could be used to treat neurogenic bladder in a rabbit model of complete spinal cord injury. | Xiaoran Wang Qi Gao Xiaoyu Yang Weihua Wang Xinquan Gu Guifeng Liu Peng Yan Ge Gao Xin Yu Yongjie Wang Jihu Lian Chaoling Shi Yao Wang Li Fan | 2012 | Neural Regeneration Research2012,7,5: | 6 |

| 7 | Competent predicate abstraction in model checking显示文摘The paper presents a new approach to computing the abstract state and a maximum weight heuristic method for finding the shortest counter-example in verification of imperative programs. The strategy is incorporated in a verification system based on the counterexample-guided abstraction refinement method. The proposed method slashes both the size of the abstract state space and the number of invokes of a decision procedure. A number of benchmarks are employed to evaluate the effectiveness of the approach. | LI Li SONG XiaoYu GU Ming LUO XiangYu | 2011 | Science China(Information Sciences)2011,54,2: | 4 |
| 8 | A preliminary study on the interaction between Asn-Gly-Arg(NGR)-modified multifunctional nanoparticles and vascular epithelial cells显示文摘Previously developed Asn-Gly-Arg(NGR) peptide-modified multifunctional poly(ethyleneimine)–poly(ethylene glycol)(PEI–PEG)-based nanoparticles(TPIC) have been considered to be promising carriers for the co-delivery of DNA and doxorubicin(DOX). As a continued effort, the aim of the present study was to further evaluate the interaction between TPIC and human umbilical vein endothelial cells(HUVEC) to better understand the cellular entry mechanism. In the present investigation,experiments relevant to co-localization, endocytosis inhibitors and factors influencing the internalization were performed. Without any treatment, there was no co-localization between aminopeptidase N/CD13(APN/CD13) and caveolin 1(CAV1). However, co-localization between CD13 and CAV1 was observed when cells were incubated with an anti-CD13 antibody or TPIC. As compared with antibody treatment,TPIC accelerated the speed and enhanced the degree of co-localization. TPIC entered HUVEC not only together with CD13 but also together with CAV1. However, this internalization was not dependent on the enzyme activity of CD13 but could be inhibited by methyl-β-eyclodextfin(MβCD), further identifying the involvement of caveolae-mediated endocytosis(CvME). This conclusion was also verified by endocytosis inhibitor experiments. | Chunxi Liu Tingxian Liu Xiaoyue Yu Yizhu Gu | 2017 | Acta Pharmaceutica Sinica B2017,7,3: | 3 |
| 9 | Dynamic cell transition and immune response landscapes of axolotl limb regeneration revealed by single-cell analysis显示文摘Dear Editor,The axolotl,Ambystoma mexicanum,has extraordinary capability to fully recover multiple tissues after lost,whereas such capability has disappeared in mammals.Thus,deci-phering detailed mechanisms underlying axolotl regenera-tion could provide valuable lessons for regenerative medicine.However,many questions,such as the origin of essential progenitor cells and key responses of individual types of cells for regeneration remain elusive(Haas and Whited,2017).Newly developed single-cell RNA sequenc-ing(scRNA-seq)method enables researchers to observe cellular and molecular dynamics in axolotl regeneration at the single-cell resolution(Gerber et al.,2018;Leigh et al.,2018),but the reported transcriptome landscapes are only for certain cell types or in certain regenerative stages.A complete overview of the regeneration process for all cell types is still lacking. | Hanbo Li Xiaoyu Wei Li Zhou Weiqi Zhang Chen Wang Yang Guo Denghui Li Jjianyang Chen Tianbin Liu Yingying Zhang Shuai Ma Congyan Wang Fujian Tan Jiangshan Xu Yang Liu Yue Yuan Liang Chen Qiaoran Wang Jing Qu Yue Shen Shanshan Liu Guangyi Fan Longqi Liu Xin Liu Yong Hou Guang-Hui Liu Ying Gu Xun Xu | 2021 | Protein & Cell2021,12,1: | 3 |
| 10 | A stringent dual control system overseeing transcription and activity of the Cre recombinase for the liver-specific conditional gene knock-out mouse model显示文摘Liver cancer is one of the most threatening diseases in Chinese population. Just like in other tissues, tumor initiation and development in liver involve multiple steps of genetic and epigenetic alterations with several unknown details. However, unlike in other tissues, a tis-sue specific inducible Cre recombinase system that allows temporal and spatial deletion of a target DNA fragment is still not available for in vivo functional gene annotation in hepatocytes. In our pursuit to establish such a mouse model, we designed a dual inducible Cre transgene system and tested it in cultured cells. By combining a CCAAT/enhancer binding protein β (C/EBP β) promoter derived Tet-off expression system and the estrogen receptor (ER) mediated functional control, we show a desirable profile of both hepatocyte-specificity and regulability of the Cre expression in a series of critical assessments in the cell culture system, which provides confidence in continua-tion of our ongoing pursuit in mouse. | Yu Wu Yinghua He Hongyu Zhang Xinlan Dai Xiaoyu Zhou Jun Gu Guan Wang Jingde Zhu | 2008 | Journal of Genetics and Genomics2008,35,7: | 3 |
| 11 | Diketopyrrolopyrrole-Au(I) as singlet oxygen generator for enhanced tumor photodynamic and photothermal therapy显示文摘Diketopyrrolopyrrole(DPP)derivatived photosensitizers(PSs)with near infrared(NIR)absorption and good photophysical properties have drawn tremendous attention in cancer phototherapy.However,current DPP derivatives present unsatisfactory quantum yield of singlet oxygen(1O2)due to the large energy gap between the excited singlet and triplet states.To tackle this challenge,herein the DPP core is functionalized with triphenylphosphine-Au(I)group(Th DPP-Au),leading to a high1O2 quantum yield of 0.65.Theoretical calculation attributes the enhancement to spin-orbit coupling and population of the triplet excition upon photoexcitation.The hydrophilic Th DPP-Au nanoparticals(NPs)are prepared via nano-reprecipitation,which displays homogeneous size and excellent light absorption ability(ε=4.382×104 M-1cm-1).And the Th DPP-Au NPs exhibit low dark toxicity and high phototoxicity,which can effectively kill tumor cells via 1O2 induced mitochondrial apoptotic pathway upon irradiation.Furthermore,in vivo experiments demonstrate that Th DPP-Au NPs can selective accumulation in tumor and present excellent synergistic photodynamic/photothermal therapy guided by fluorescence and photothermal dual imaging. | Xiaoyu Huang Rui Gu Jiewei Li Nan Yang Zijin Chen Weili Si Peng Chen Wei Huang Xiaochen Dong | 2020 | Science China Chemistry2020,63,1: | 3 |

| 13 | Advanced inorganic/polymer hybrid electrolytes for all-solid-state lithium batteries显示文摘Solid-state batteries have become a frontrunner in humankind’s pursuit of safe and stable energy storage systems with high energy and power density.Electrolyte materials,currently,seem to be the Achilles’heel of solid-state batteries due to the slow kinetics and poor interfacial wetting.Combining the merits of solid inorganic electrolytes(SIEs)and solid polymer electrolytes(SPEs),inorganic/polymer hybrid electrolytes(IPHEs)integrate improved ionic conductivity,great interfacial compatibility,wide electrochemical stability window,and high mechanical toughness and flexibility in one material,having become a sought-after pathway to high-performance all-solid-state lithium batteries.Herein,we present a comprehensive overview of recent progress in IPHEs,including the awareness of ion migration fundamentals,advanced architectural design for better electrochemical performance,and a perspective on unconquered challenges and potential research directions.This review is expected to provide a guidance for designing IPHEs for next-generation lithium batteries,with special emphasis on developing high-voltage-tolerance polymer electrolytes to enable higher energy density and three-dimensional(3D)continuous ion transport highways to achieve faster charging and discharging. | Xiaoyu JI Yiruo ZHANG Mengxue CAO Quanchao GU Honglei WANG Jinshan YU Zi-Hao GUO Xingui ZHOU | 2022 | Journal of Advanced Ceramics2022,11,6: | 2 |
| 14 | A spontaneous thermo-sensitive female sterility mutation in rice enables fully mechanized hybrid breeding显示文摘Male sterility enables hybrid crop breeding to increase yields and has been extensively studied. But thermo-sensitive female sterility, which is an ideal property that may enable full mechanization in hybrid rice breeding, has rarely been investigated due to the absence of such germplasm. Here we identify the spontaneous thermo-sensitive female sterility 1 (tfs1) mutation that confers complete sterility under regular/high temperature and partial fertility under low temperature as a point mutation in ARGONAUTE7 (AGO7). AGO7 associates with miR390 to form an RNA-Induced Silencing Complex (RISC), which triggers the biogenesis of small interfering RNAs (siRNAs) from TRANS-ACTING3 (TAS3) loci by recruiting SUPPRESSOR OF GENE SILENCING (SGS3) and RNA-DEPENDENT RNA POLYMERASE6 (RDR6) to TAS3 transcripts. These siRNAs are known as tasiR-ARFs as they act in trans to repress auxin response factor genes. The mutant TFS1 (mTFS1) protein is compromised in its ability to load the miR390/miR390* duplex and eject miR390* during RISC formation. Furthermore, tasiR-ARF levels are reduced in tfs1 due to the deficiency in RDR6 but not SGS3 recruitment by mTFS1 RISC under regular/high temperature, while low temperature partially restores mTFS1 function in RDR6 recruitment and tasiR-ARF biogenesis. A miR390 mutant also exhibits female sterility, suggesting that female fertility is controlled by the miR390-AGO7 module. Notably, the tfs1 allele introduced into various elite rice cultivars endows thermo-sensitive female sterility. Moreover, field trials confirm the utility of tfs1 as a restorer line in fully mechanized hybrid rice breeding. | Haoxuan Li Chenjiang You Manabu Yoshikawa Xiaoyu Yang Haiyong Gu Chuanguo Li Jie Cui Xuemei Chen Nenghui Ye Jianhua Zhang Guanqun Wang | 2022 | Cell Research2022,32,10: | 2 |
| 15 | A Review of Durable Flame‑Retardant Fabrics by Finishing:Fabrication Strategies and Challenges显示文摘Fabrics with durable flame retardancy are of great importance for preventing potential fire threats in daily life.This review presents a comprehensive discussion of advances in durable flame-retardant fabrics by finishing over the decade.The environmentally sustainable and toxicologically acceptable strategies for improving the durable flame retardancy of fabrics are classified into six types:.(i)the formation of covalent bonds,(ii)the formation of crosslinking networks,(iii)the formation of water-insoluble products,(iv)the use of adhesive layers,(v)the construction of hydrophobic layers,and(vi)the intercalation of flame-retardants into fibres.The design principles,methodologies,and existing problems of different fabrication strategies for imparting durable flame retardancy are summarized and reviewed.The advantages and disadvantages of each strategy are critically discussed.The current challenges and future opportunities are also proposed based on the current market requirements and state-of-the-art technologies.Many recent methodologies have great potential for replacing the conventional durable flame-retardant processes of cellulosic textiles. | Peng Qi Feng Chen Yuchun Li Hongfei Li Xiaoyu Gu Jun Sun Sheng Zhang | 2023 | Advanced Fiber Materials2023,5,3: | 2 |

| 19 | Vitamin B6 regulates IL-33 homeostasis to alleviate type 2 inflammation显示文摘Interleukin-33(IL-33)is a crucial nuclear cytokine that induces the type 2 immune response and maintains immune homeostasis.The fine-tuned regulation of IL-33 in tissue cells is critical to control of the type 2 immune response in airway inflammation,but the mechanism is still unclear.Here,we found that healthy individuals had higher phosphate-pyridoxal(PLP,an active form of vitamin B6)concentrations in the serum than asthma patients.Lower serum PLP concentrations in asthma patients were strongly associated with worse lung function and inflammation.In a mouse model of lung inflammation,we revealed that PLP alleviated the type 2 immune response and that this inhibitory effect relied on the activity of IL-33.A mechanistic study showed that in vivo,pyridoxal(PL)needed to be converted into PLP,which inhibited the type 2 response by regulating IL-33 stability.In mice heterozygous for pyridoxal kinase(PDXK),the conversion of PL to PLP was limited,and IL-33 levels were increased in the lungs,aggravating type 2 inflammation.Furthermore,we found that the mouse double minute 2 homolog(MDM2)protein,an E3 ubiquitin-protein ligase,could ubiquitinate the N-terminus of IL-33 and sustain IL-33 stability in epithelial cells.PLP reduced MDM2-mediated IL-33 polyubiquitination and decreased the level of IL-33 through the proteasome pathway.In addition,inhalation of PLP alleviated asthma-related effects in mouse models.In summary,our data indicate that vitamin B6 regulates MDM2-mediated IL-33 stability to constrain the type 2 response,which might help develop a potential preventive and therapeutic agent for allergy-related diseases. | Songling Zhu Shufen Zhong Kebin Cheng Li-Sha Zhang Jiu-wu Bai Zu Cao Su Wang Wen Chen Shipeng Cheng Liyan Ma Zhiyang Ling Yuying Huang Wangpeng Gu Xiaoyu Sun Chunyan Yi Meng Zhao Shuo Liang Jin-Fu Xu Bing Sun Yaguang Zhang | 2023 | Cellular & Molecular Immunology2023,20,7: | 1 |
