2Origin and Evolution of Core Components Responsible for Monitoring Light Environment Changes during Plant Terrestrialization显示文摘Light serves as the source of energy as well as an information signal for photosynthetic plants. During evolution, plants have acquired the ability to monitor environmental light radiation and adjust their developmental patterns to optimally utilize light energy for photosynthesis. The mechanisms of light perception and signal transduction have been comprehensively studied in past decades, mostly in a few model plants, including Arabidopsis thaliana. However, systematic analyses of the origin and evolution of core components involved in light perception and signaling are still lacking. In this study, we took advantage of the recently sequenced genomes and transcriptomes covering all the main Archaeplastida clades in the public domain to identify orthologous genes of core components involved in light perception and signaling and to reconstruct their evolutionary history. Our analyses suggested that acclimation to different distribution of light quality in new environments led to the origination of specific light signaling pathways in plants. The UVR8 (UV Resistance Locus 8) signaling pathway originated during the movement of plants from the deeper sea to shallow water and enabled plants to deal with ultraviolet B light (UV-B). After acquisition of UV-B adaptation, origination of the phytochrome signaling pathway helped plants to colonize water surface where red light became the prominent light energy source. The seedling emergence pathway, which is mediated by a combination of light and phytohormone signals that orchestrate plant growth pattern transitions, originated before the emergence of seed plants. Although cryptochromes and some key components of E3 ubiquitin ligase systems already existed before the divergence of the plant and animal kingdoms, the coevolution and optimization of light perception and downstream signal transduction components, including key transcription factors and E3 ubiquitin ligase systems, are evident during plant terrestrialization.Xue Han Xin Chang Zhenhua Zhang Haodong Chen Hang He Bojian Zhong Xing Wang Deng 2019Molecular Plant2019,12,6:9
3High performance columnar-like Fe2O3@carbon composite anode via yolk@shell structural design显示文摘Conversion-type reaction anode materials with high specific capacity are attractive candidates to improve lithium ion batteries(LIBs), yet the rapid capacity fading and poor rate capability caused by drastic volume change and low electronic conductivity greatly hinder their practical applications. To circumvent these issues, the successful design of yolk@shell Fe2 O3@C hybrid composed of a columnar-like Fe2O3 core within a hollow cavity completely surrounded by a thin, self-supported carbon(C) shell is presented as an anode for high-performance LIBs. This yolk@shell structure allows each Fe2O3 core to swell upon lithiation without deforming the carbon shell. This preserves the structural and electrical integrity against pulverization, as revealed by in situ transmission electron microscopy(TEM) measurement. Benefiting from these structural advantages, the resulting electrode exhibits a high reversible capacity(1013 m Ah g-1 after80 cycles at 0.2 A g-1), outstanding rate capability(710 m Ah g-1 at 8 A g-1) and superior cycling stability(800 m Ah g-1 after 300 cycles at 4 A g-1). A Li-ion full cell using prelithiated yolk@shell Fe2 O3@C hybrid as the anode and commercial Li CoO2(LCO) as the cathode demonstrates impressive cycling stability with a capacity retention of 84.5% after 100 cycles at 1 C rate, holding great promise for future practical applications.Zhiming Zheng Pei Li Jason Huang Haodong Liu Yi Zao Zhongli Hu Li Zhang Huixin Chen Ming-Sheng Wang Dong-Liang Peng Qiaobao Zhang 2020Journal of Energy Chemistry2020,29,2:7
4Pros and Cons: Autophagy in Acute Spinal Cord Injury显示文摘Autophagy plays an important role in the development and pathogenesis of various diseases. It can be induced by a variety of events such as hypoxia, nutrient-starvation, and mechanical damage. Many neurological disorders such Parkinson’s disease, Alzheimer’s disease, amyotrophic lateral sclerosis, Huntington’s disease, cerebral ischemia, and acute spinal cord injury (ASCI), are closely related to autophagy. However, therapeutic strategies to manipulate autophagy have not yet been fully deciphered due to the limited knowledge of the molecular mechanisms underlying autophagy in these disorders.Zheng Li Tianshi Chen Yuanwu Cao Xiaoxing Jiang Haodong Lin Jian Zhang Zixian Chen 2019Neuroscience Bulletin2019,35,5:6
5Effective and biocompatible antibacterial surfaces via facile synthesis and surface modification of peptide polymers显示文摘It is an urgent need to tackle drug-resistance microbial infections that are associated with implantable biomedical devices.Host defense peptide-mimicking polymers have been actively explored in recent years to fight against drug-resistant microbes.Our recent report on lithium hexamethyldisilazide-initiated superfast polymerization on amino acid N-carboxyanhydrides enables the quick synthesis of host defense peptide-mimicking peptide polymers.Here we reported a facile and cost-effective thermoplastic polyurethane(TPU)surface modification of peptide polymer(DLL:BLG=90:10)using plasma surface activation and substitution reaction between thiol and bromide groups.The peptide polymer-modified TPU surfaces exhibited board-spectrum antibacterial property as well as effective contact-killing ability in vitro.Furthermore,the peptide polymer-modified TPU surfaces showed excellent biocompatibility,displaying no hemolysis and cytotoxicity.In vivo study using methicillin-resistant Staphylococcus aureus(MRSA)for subcutaneous implantation infectious model showed that peptide polymer-modified TPU surfaces revealed obvious suppression of infection and great histocompatibility,compared to bare TPU surfaces.We further explored the antimicrobial mechanism of the peptide polymer-modified TPU surfaces,which revealed a surface contact-killing mechanism by disrupting the bacterial membrane.These results demonstrated great potential of the peptide-modified TPU surfaces for practical application to combat bacterial infections that are associated with implantable materials and devices.Ziyi Lu Yueming Wu Zihao Cong Yuxin Qian Xue Wu Ning Shao Zhongqian Qiao Haodong Zhang Yunrui She Kang Chen Hengxue Xiang Bin Sun Qian Yu Yuan Yuan Haodong Lin Meifang Zhu Runhui Liu 2021Bioactive Materials2021,6,12:5
62D hierarchical yolk-shell heterostructures as advanced host-interlayer integrated electrode for enhanced Li-S batteries显示文摘Lithium sulfur(Li-S)batteries hold great promising for high-energy-density batteries,but appear rapid capacity fading due to the lack of overall and elaborated design of both sulfur host and interlayer.Herein,we developed a novel two-dimensional(2D)hierarchical yolk-shell heterostructure,constructed by a graphene yolk,2D void and outer shell of vertically aligned carbon-mediated MoS2 nanosheets(G@void@MoS2/C),as advanced host-interlayer integrated electrode for Li-S batteries.Notably,the 2D void,with a typical thickness of^80 nm,provided suitable space for loading and confining nano sulfur,and vertically aligned ultrathin MoS2 nanosheets guaranteed enriched catalytically active sites to effectively promote the transition of soluble polysulfides.The conductive graphene yolk and carbon mediated shell sufficiently accelerated electron transport.Therefore,the integrated electrode of G@void@MoS2/C not only exceptionally confined the sulfur/polysulfides in 2D yolk-shell heterostructures,but also achieved catalytic transition of the residual polysulfides dissolved in electrolyte to solid Li2S2/Li2S,both of which synergistically achieved an extremely low capacity fading rate of 0.05%per cycle over 1000 times at 2C,outperforming most reported Mo based cathodes and interlayers for Li-S batteries.2D hierarchical yolkshell heterostructures developed here may shed new insight on elaborated design of integrated electrodes for Li-S batteries.Yanfeng Dong Pengfei Lu Haodong Shi Jieqiong Qin Jian Chen Wencai Ren Hui-Ming Cheng Zhong-Shuai Wu 2019Journal of Energy Chemistry2019,28,9:4
7Advances in 3D bioprinting technology for cardiac tissue engineering and regeneration显示文摘Cardiovascular disease is still one of the leading causes of death in the world,and heart transplantation is the current major treatment for end-stage cardiovascular diseases.However,because of the shortage of heart donors,new sources of cardiac regenerative medicine are greatly needed.The prominent development of tissue engineering using bioactive materials has creatively laid a direct promising foundation.Whereas,how to precisely pattern a cardiac structure with complete biological function still requires technological breakthroughs.Recently,the emerging three-dimensional(3D)bioprinting technology for tissue engineering has shown great advantages in generating micro-scale cardiac tissues,which has established its impressive potential as a novel foundation for cardiovascular regeneration.Whether 3D bioprinted hearts can replace traditional heart transplantation as a novel strategy for treating cardiovascular diseases in the future is a frontier issue.In this review article,we emphasize the current knowledge and future perspectives regarding available bioinks,bioprinting strategies and the latest outcome progress in cardiac 3D bioprinting to move this promising medical approach towards potential clinical implementation.Nanbo Liu Xing Ye Bin Yao Mingyi Zhao Peng Wu Guihuan Liu Donglin Zhuang Haodong Jiang Xiaowei Chen Yinru He Sha Huang Ping Zhu 2021Bioactive Materials2021,6,5:4

9Activation of peracetic acid by metal-organic frameworks(ZIF-67)for efficient degradation of sulfachloropyridazine显示文摘Peracetic acid(PAA)-based system is becoming an emerging advanced oxidation process(AOP)for effective removal of organic contaminants from water.Various approaches have been tested to activate PAA,while no previous researches reported the application of metal-organic frameworks(MOFs)materials for PAA activation.In this study,zeolitic imidazole framework(ZIF)-67,a representative MOFs,was facile synthesized via direct-mixing method at room temperature,and tested for PAA activation and sulfachloropyridazine(SCP)degradation.The as-synthesized ZIF-67 exhibited excellent performance for PAA activation and SCP degradation with 100%of SCP degraded within 3 min,owing to the specific MOFs structure and abundant Co^(2+) sites.The pseudo-first-order kinetic model was applied to fit the kinetic data,with rate constant k_(1) of ZIF-67 activated PAA system 34.2 and 156.5 times higher than those of conventional Co_(3)O_(4)activated PAA and direct oxidation by PAA.Radical quenching experiments and electron paramagnetic resonance(EPR)analysis indicated that CH_(3)C(O)OO^(·)played a major role in this PAA activation system.Then,the Fukui index based on density functional theory(DFT)calculation was used to predict the possible reaction sites of SCP for electrophilic attack by CH_(3)C(O)OO^(·).In addition,the degradation pathway of SCP was proposed based on Fukui index values and intermediates detection,which mainly included the S-N bond cleavage and SO_(2)extrusion and followed by further oxidation,dechlorination,and hydroxylation.Therefore,ZIF-67 activated PAA is a novel strategy and holds strong potential for the removal of emerging organic contaminants(EOCs)from water.Jun Duan Long Chen Haodong Ji Peishen Li Fan Li Wen Liu 2022Chinese Chemical Letters2022,33,6:3
10Image processing operations identification via convolutional neural network显示文摘Dear editor,In recent years,image forensics has attracted increasing attention,and many forensic methods have been proposed for identifying image processing operations.Until now,most existing methods have been based on hand-crafted features,and only one specific operation is considered in these methods.In many forensic scenarios,however,multiple classification for various image processing operations is more practical.In addition,for some image processing operations,it is difficult to construct effective hand-crafted features.In this study,we therefore propose a new method based on convolutional neural networks(CNNs)to adaptively learn discriminative features for identifying typical image processing operations.However,directly employ CNN structures in other fields(e.g.,computer vision)for image forensics cannot obtain satisfactory performance.Thus,we carefully design the network structures(including the highpass filter bank,the channel expansion layer,the pooling layers,and the activation functions)of the proposed method.Experimental results show that the proposed method outperforms the current best method,which is based on hand-crafted features,and three related methods based on CNNs for image steganalysis and/or forensics,achieving stateof-the-art results.Furthermore,we provide supplementary results to show the rationality and robustness of the proposed model.Bolin CHEN Haodong LI Weiqi LUO Jiwu HUANG 2020Science China(Information Sciences)2020,63,3:3
11Application of Optical Tweezers in the Research of Molecular Interaction between Lymphocyte Function Associated Antigen-1 and Its Monoclonal Antibody显示文摘Lymphocyte function associated antigen-1 (CD11a/CD18, LFA-1) plays an important role in the structure of the immunological synapse and is required for efficient lysis of cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells. To study the activation mode of LFA-1 on the NK cell surface, optical tweezers were used in the work. As an emerging technology, optical tweezers are widely used to manipulate microscopic objects and measure the forces of molecular interactions in the field of biological research. In our study, a new platform was constructed to study the single molecular behavior of receptor on cell surface using optical tweezers. Based on the platform, the interaction between an NK cell and a polystyrene microsphere coated with anti-LFA-1 antibody was observed. The result confirmed that the adhesion forces between an NK cell and a polystyrene bead were time-dependent. According to our findings, we propose that anti-LFA-1 antibody may cause the clustering of LFA-1 on NK cell surface.Haodong Chen Kuikui Ge Yinmei Li Jianguang Wu Yongqiang Gu Haiming Wei Zhigang Tian 2007Cellular & Molecular Immunology2007,4,3:3
12Self-Stabilized Precipitation Polymerization and Its Application显示文摘An efective,value-added use of the large amounts of olefnic compounds produced in the processing of petroleum,aside from ethylene and propylene,has been a long outstanding challenge.Here,we developed a novel heterogeneous polymerization method,beyond emulsion/dispersion/suspension,termed self-stabilized precipitation(2SP)polymerization,which involves the nucleation and growth of nanoparticles(NPs)of a well-defned size without the use of any stabilizers and multifunctional monomers(crosslinker).Tis technique leads to two revolutionary advances:(1)the generation of functional copolymer particles from single olefnic monomer or complex olefnic mixtures(including C4/C5/C9 fractions)in large quantities,which open a new way to transform huge amount of unused olefnic compounds in C4/C5/C9 fractions into valuable copolymers,and(2)the resultant polymeric NPs possess a self-limiting size and narrow size distribution,therefore being one of the most simple,efcient,and green strategies to produce uniform,size-tunable,and functional polymeric nanoparticles.More importantly,the separation of the NPs from the reaction medium is simple and the supernatant liquid can be reused;hence this new synthetic strategy has great potential for industrial production.Zhenjie Liu Dong Chen Jinfang Zhang Haodong Liao Yanzhao Chen Yingfa Sun Jianyuan Deng Wantai Yang 2018Research2018,,1:3
13Helmholtz Solving and Performance Optimization in Global/Regional Assimilation and Prediction System显示文摘Despite efficient parallelism in the solution of physical parameterization in the Global/Regional Assimilation and Prediction System(GRAPES),the Helmholtz equation in the dynamic core,with the increase of resolution,can hardly achieve sufficient parallelism in the solving process due to a large amount of communication and irregular access.In this paper,optimizing the Helmholtz equation solution for better performance and higher efficiency has been an urgent task.An optimization scheme for the parallel solution of the Helmholtz equation is proposed in this paper.Specifically,the geometrical multigrid optimization strategy is designed by taking advantage of the data anisotropy of grid points near the pole and the isotropy of those near memory equator in the Helmholtz equation,and the Incomplete LU(ILU)decomposition preconditioner is adopted to speed up the convergence of the improved Generalized Conjugate Residual(GCR),which effectively reduces the number of iterations and the computation time.The overall solving performance of the Helmholtz equation is improved by thread-level parallelism,vectorization,and reuse of data in the cache.The experimental results show that the proposed optimization scheme can effectively eliminate the bottleneck of the Helmholtz equation as regards the solving speed.Considering the test results on a 10-node two-way server,the solution of the Helmholtz equation,compared with the original serial version,is accelerated by 100,with one-third of iterations reduced.Jianqiang Huang Wei Xue Haodong Bian Wenxin Yan Xiaoying Wang Wenguang Chen 2021Tsinghua Science and Technology2021,26,3:2
14A novel CRISPR/Cas9 system for efficiently generating Cas9- free multiplex mutants in Arabidopsis显示文摘The CRISPR/Cas9 genome-editing system has emerged as a popular powerful tool for biological research.However,the process of selecting efficiently edited Cas9-free plants is usually laborious and time consuming.Here,we demonstrated P2A to be the most efficient self-cleaving peptide for fusing Cas9 and GFP in Arabidopsis and then used Cas9-P2A-GFP to develop a novel CRISPR/Cas9 system.Additionally,a pair of isocaudomer restriction enzymes were selected to conveniently assemble multiple sgRNAs.In this system,the GFP fluorescence intensity in T1 transgenic plants indicates the expression level of the Cas9 protein,which correlates well with the editing efficiency.Furthermore,Cas9-free plants can be easily selected by examining GFP fluorescence in T2 transgenic plants.The efficient knockout of BRI1,BZR1 and BES1 demonstrated the robustness of our new system.Thus,we designed a novel CRISPR/Cas9 system that can generate Cas9-free multiplex mutants efficiently in Arabidopsis and possibly in other plant species.Jiajun Wang Haodong Chen 2020aBIOTECH2020,1,1:2
15Reliability and global sensitivity analysis for an airplane slat mechanism considering wear degradation显示文摘This paper focuses on the issue of reliability and global sensitivity analysis for an airplane slat mechanism considering the uncertainties in the wear process of mechanical components.First,the multi-body kinematic model of the slat mechanism is built in the ADAMS software.The geometrical sizes of the roller wheels after wear degradation are considered as input variables and the angle the slat should turn is considered as the output response.To accurately identify the influential roller wheels to the reliability and robustness of the slat mechanism,the failure probability based sensitivity and variance-based sensitivity indices are introduced.Comprehensive analysis of the results have shown that the reliability analysis and global sensitivity theory can help engineers find significant parts by their contributions,thus provide guidance for mechanical design and maintenance.Changcong ZHOU Haodong ZHAO Qi CHANG Mengyao JI Chen LI 2021Chinese Journal of Aeronautics2021,34,1:2
16Global antimicrobial resistance:a system-wide comprehensive investigation using the Global One Health Index显示文摘Background:Antimicrobial resistance(AMR)is one of the top ten global public health challenges.However,given the lack of a comprehensive assessment of worldwide AMR status,our objective is to develop a One Health-based system-wide evaluation tool on global AMR.Methods:We have further developed the three-hierarchical Global One Health Index(GOHI)-AMR indicator scheme,which consists of five key indicators,17 indicators,and 49 sub-indicators,by incorporating 146 countries'data from diverse authoritative databases,including WHO's Global Antimicrobial Resistance and Use Surveillance System(GLASS)and the European CDC.We investigated the overall-or sub-rankings of GOHI-AMR at the international/regional/national levels for data preprocessing and score calculation utilizing the existing GOHI methodology.Additionally,a correlation analysis was conducted between the GOHI-AMR and other socioeconomic factors.Results:The average GOHI-AMR score for 146 countries is 38.45.As expected,high-income countries(HICs)outperform the other three income groups on overall rankings and all five key indicators of GOHI-AMR,whereas lowincome countries unexpectedly outperform upper-middle-income countries and lower-middle-income countries on the antibiotics-resistant key indicator(ARR)and ARR-subordinate indicators,including carbapenem-,β-lactam-,and quinolone resistance,and even HICs on aminoglycoside resistance.There were no significant differences among the four groups on the environmental-monitoring indicator(P>0.05).GOHI-AMR was positively correlated with gross domestic product,life expectancy,and AMR-related publications,but negatively with natural growth rate and chronic respiratory disease.In contrast to Cyprus,the remarkably lower prevalence of'ESKAPE pathogens'in high-scoring Sweden and Denmark highlights Europe's huge gaps.China and Russia outperformed the other three BRICS countries on all key indicators,particularly India's ARR and Brazil's AMR laboratory network and coordination capacity.Furthermore,significant internal disparities in carbapenem-resistant Klebsiella pneumoniae(CRKP)and methicillin-resistant Staphylococcus aureus(MRSA)prevalence were observed between China and the USA,with MRSA prevalence both gradually declining,whereas CRKP prevalence has been declining in the USA but increasing in China,consistent with higher carbapenems-related indicator'performance in USA.Conclusions:GOHI-AMR is the most comprehensive tool currently available for the assessment of AMR status worldwide.We discovered unique features impacting AMR in each country and offered precise recommendations to improve the capacity to tackle AMR in low-ranking countries.Nan Zhou Zile Cheng Xiaoxi Zhang Chao Lv Chaoyi Guo Haodong Liu Ke Dong Yan Zhang Chang Liu Yunfu Chang Sheng Chen Xiaokui Guo Xiao-Nong Zhou Min Li Yongzhang Zhu 2022Infectious Diseases of Poverty2022,11,4:2
17FRET-based polymer materials for detection of cellular microenvironments显示文摘Effective detection of cellular microenvironments and understanding of physiological activities in living cells remain a considerable challenge.In recent years,fluore scence(or Forster)resonance energy trans fe r(FRET)technology has emerged as a valuable method for real-time imaging of intracellular environment with high sensitivity,specificity and spatial resolution.Particularly,polymer-based imaging systems show enhanced stability,improved biodistribution,increased dye payloads,and amplified signal/noise ratio compared with small molecular sensors.This review summarizes the recent progress in FRET-based polymeric systems for probing the physiological environments in cells.Chuang Weng Nianqing Fan Taoran Xu Haodong Chen Zifen Li Yiwen Li Hong Tan Qiang Fu Mingming Ding 2020Chinese Chemical Letters2020,31,6:1
18Exploring the genetic characteristics of 93-11 and Nipponbare recombination inbred lines based on the Golden Gate SNP assay显示文摘Understanding genetic characteristics in rice populations will facilitate exploring evolutionary mechanisms and gene cloning. Numerous molecular markers have been utilized in linkage map construction and quantitative trait locus(QTL) mappings. However, segregation-distorted markers were rarely considered, which prevented understanding genetic characteristics in many populations. In this study, we designed a 384-marker Golden Gate SNP array to genotype 283 recombination inbred lines(RILs) derived from 93-11 and Nipponbare Oryza sativa crosses. Using 294 markers that were highly polymorphic between parents, a linkage map with a total genetic distance of 1,583.2 c M was constructed, including 231 segregation-distorted markers. This linkage map was consistent with maps generated by other methods in previous studies. In total, 85 significant quantitative trait loci(QTLs) with phenotypic variation explained(PVE) values?5% were identified. Among them, 34 QTLs were overlapped with reported genes/QTLs relevant to corresponding traits, and 17 QTLs were overlapped with reported sterility-related genes/QTLs. Our study provides evidence that segregation-distorted markers can be used in linkage map construction and QTL mapping. Moreover, genetic information resulting from this study will help us to understand recombination events and segregation distortion. Furthermore, this study will facilitate gene cloning and understanding mechanism of inter-subspecies hybrid sterility and correlations with important agronomic traits in rice.Renbo Yu Wei Yan Manzhong Liang Xiaojun Dai Haodong Chen Yunong Sun Xingwang Deng Xiangding Chen Hang He Liangbi Chen 2016Science China(Life Sciences)2016,59,7:1

20Efficient activation of peroxymonosulfate by hollow cobalt hydroxide for degradation of ibuprofen and theoretical study显示文摘Hollow microsphere structure cobalt hydroxide(h-Co(OH)2) was synthesized via an optimized solvothermal-hydrothermal process and applied to activate peroxymonosulfate(PMS) for degradation of a typical pharmaceutically active compound,ibuprofen(IBP).The material characterizations confirmed the presence of the microscale hollow spheres with thin nanosheets shell in h-Co(OH)2,and the crystalline phase was assigned to a-Co(OH)2.h-Co(OH)2 could efficiently activate PMS for radicals production,and 98.6% of IBP was degraded at 10 min.The activation of PMS by h-Co(OH)2 was a pHindependent process,and pH 7 was the optimum condition for the activation-degradation system.Scavenger quenching test indicated that the sulfate radical(SO4^·-) was the primary reactive oxygen species for IBP degradation,which contributed to 75.7%.Fukui index(f^-) based on density functional theory(DFT) calculation predicted the active sites of IBP molecule for SO4^·- attack,and then IBP degradation pathway was proposed by means of intermediates identification and theoretical calculation.The developed hollow Co(OH)2 used to efficiently activate PMS is promising and innovative alternative for organic contaminants removal from water and wastewater.Mingfeng Ma Long Chen Jingzhu Zhao Wen Liu Haodong Ji 2019Chinese Chemical Letters2019,30,12:1
