4Genome Engineering in Rice Using Cas9 Variants that Recognize NG PAM Sequences显示文摘CRISPR/Cas9 genome editing relies on sgRNA-target DNA base pairing and a short downstream PAM sequence to recognize target DNA. The strict protospacer adjacent motif (PAM) requirement hinders applications of the CRISPR/Cas9 system since it restricts the targetable sites in the genomes. xCas9 and SpCas9-NG are two recently engineered SpCas9 variants that can recognize more relaxed NG PAMs, implying a great potential in addressing the issue of PAM constraint. Here we use stable transgenic lines to evaluate the efficacies of xCas9 and SpCas9-NG in performing gene editing and base editing in rice. We found that xCas9 can efficiently induce mutations at target sites with NG and GAT PAM sequences in rice. However, base editors containing xCas9 failed to edit most of the tested target sites. SpCas9-NG exhibited a robust editing activity at sites with various NG PAMs without showing any preference for the third nucleotide after NG. Moreover, we showed that xCas9 and SpCas9-NG have higher specificity than SpCas9 at the CGG PAM site. We further demonstrated that different forms of cytosine or adenine base editors containing SpCas9-NG worked efficiently in rice with broadened PAM compatibility. Taken together, our work has yielded versatile genome-engineering tools that will significantly expand the target scope in rice and other crops.Kai Hua Xiaoping Tao Peijin Han Rui Wang Jian-Kang Zhu 2019Molecular Plant2019,12,7:22
5Multiplex gene editing in rice with simplified CRISPR-Cpf1 and CRISPR-Cas9 systems显示文摘We developed simplified single transcriptional unit(SSTU) CRISPR systems for multiplex gene editing in rice using FnCpf1, LbCpf1 or Cas9, in which the nuclease and its cr RNA array are co-expressed from a single Pol Ⅱ promoter, without any additional processing machinery. Our SSTU systems are easy to construct and effective in mediating multiplex genome editing.Mugui Wang Yanfei Mao Yuming Lu Zhidan Wang Xiaoping Tao Jian-Kang Zhu 2018Journal of Integrative Plant Biology2018,60,8:21
6The China Alzheimer Report 2022显示文摘China’s population has rapidly aged over the recent decades of social and economic development as neurodegenerative disorders have proliferated,especially Alzheimer’s disease(AD)and related dementias(ADRD).AD’s incidence rate,morbidity,and mortality have steadily increased to make it presently the fifth leading cause of death among urban and rural residents in China and magnify the resulting financial burdens on individuals,families and society.The‘Healthy China Action’plan of 2019-2030 promotes the transition from disease treatment to health maintenance for this expanding population with ADRD.This report describes related epidemiological trends,evaluates the economic burden of the disease,outlines current clinical diagnosis and treatment status and delineates existing available public health resources.More specifically,it examines the public health impact of ADRD,including prevalence,mortality,costs,usage of care,and the overall effect on caregivers and society.In addition,this special report presents technical guidance and supports for the prevention and treatment of AD,provides expertise to guide relevant governmental healthcare policy development and suggests an information platform for international exchange and cooperation.Rujing Ren Jinlei Qi Shaohui Lin Xinya Liu Peng Yin Zhihui Wang Ran Tang Jintao Wang Qiang Huang Jianping Li Xinyi Xie Yongbo Hu Shishuang Cui Yuan Zhu Xiaoping Yu Pengfei Wang Yikang Zhu Yiran Wang Yanyan Huang Yisong Hu Ying Wang Chunbo Li Maigeng Zhou Gang Wang 2022General Psychiatry2022,35,1:20

8Recent advances in gel polymer electrolyte for high-performance lithium batteries显示文摘Lithium batteries (LBs) have become increasingly important energy storage systems in our daily life. However, their practical applications are still severely plagued by the safety issues from liquid electrolyte, especially when the batteries are exposed to mechanical, thermal, or electrical abuse conditions. Gel polymer electrolytes (GPEs) are being considered as an effective solution to replace currently available organic liquid electrolyte for building safer LBs. This review provides recent advancements in GPEs applied for high-performance LBs. On the one hand, from the environmental and economic point of view, the skeletons of GPEs changed from traditional polymer to renewable and degradable polymer. On the other hand, in addition to being as a component with good electrochemical and physical characterizations, the GPEs also need to provide some functions for addressing the concerns of lithium (Li) dendrites, unstable cathode electrolyte interface, dissolution and migration of transition metal ions,'shuttle effect' of polysulfides, and so on. Finally, to synchronously meet the challenges from the advanced cathode and Li metal anode, the bio-based GPEs with multi-functionality are proposed to develop high-energy/powerdensity batteries in the future.Ming Zhu Jiaxin Wu Yue Wang Mingming Song Lei Long Sajid Hussain Siyal Xiaoping Yang Gang Sui 2019Journal of Energy Chemistry2019,28,10:17
9The ion chemistry of surface and ground waters in the Taklimakan Desert of Tarim Basin,western China显示文摘The physio-chemical and chemical features of water in natural conditions are controlled by the weath-ering of bedrocks,local climate,landforms and other geo-environmental parameters. In order to un-derstand the characteristics of water and the origins of the dissolved loads in the rivers and in the ground waters of the Taklimakan Desert,western China,we studied the ions in the water samples col-lected from rivers and wells. We collected water samples from four rivers (Keriya River,Cele River,Tumiya River and Yulongkashi River) in the southern desert and ground water samples from many parts of the desert. Major cations and anions were measured using ion-chromatograph and titration with HCl. The total dissolved solids (TDS),pH and conductivity were examined on site by a portable multi-parameter analyzer. The data show that the water in the rivers of southern Taklimakan is still of fresh water quality and slight alkalinity,although the TDS is comparatively higher than that of many other rivers of the world. The ground water is fresh to slightly saline,with TDS a little higher than that of river water in the study area. The concentration of ions is slightly different between the four rivers in the southern Taklimakan. However,the chemistries of ground water in all samples are to a large degree controlled by sodium and chloride. The ions in the ground water are concluded to be mainly from dissolving of evaporites,consistent with the dry climate in the region,whereas the ions in the rivers are mainly from rock weathering. Low-level human imprints are recognized in the ground water samples also.ZHU BingQi YANG XiaoPing 2007Chinese Science Bulletin2007,52,15:15
10Triboelectric–Electromagnetic Hybrid Generator for Harvesting Blue Energy显示文摘Progress has been developed in harvesting lowfrequency and irregular blue energy using a triboelectric–electromagnetic hybrid generator in recent years. However,the design of the high-efficiency, mechanically durable hybrid structure is still challenging. In this study, we report a fully packaged triboelectric–electromagnetic hybrid generator(TEHG), in which magnets were utilized as the trigger to drive contact–separation-mode triboelectric nanogenerators(CS-TENGs) and coupled with copper coils to operate rotary freestanding-mode electromagnetic generators(RF-EMGs). The magnet pairs that produce attraction were used to transfer the external mechanical energy to the CS-TENGs, and packaging of the CS-TENGpart was achieved to protect it from the ambient environment. Under a rotatory speed of 100 rpm, the CS-TENGs enabled the TEHG to deliver an output voltage, current,and average power of 315.8 V, 44.6 μA, and ~ 90.7 μW,and the output of the RF-EMGs was 0.59 V, 1.78 m A, and 79.6 μW, respectively. The cylinder-like structure made the TEHG more easily driven by water flow and demonstrated to work as a practical power source to charge commercial capacitors. It can charge a 33μF capacitor from 0 to 2.1 V in 84 s, and the stored energy in the capacitor can drive an electronic thermometer and form a self-powered water-temperature sensing system.Huiyun Shao Ping Cheng Ruixuan Chen Lingjie Xie Na Sun Qingqing Shen Xiaoping Chen Qianqian Zhu Yi Zhang Yina Liu Zhen Wen Xuhui Sun 2018Nano-Micro Letters2018,10,3:9
11Application of Active Flow Control Technique for Gust Load Alleviation显示文摘A new gust load alleviation technique is presented in this paper based on active flow control. Numerical studies are conducted to investigate the beneficial effects on the aerodynamic characteristics of the quasi 'Global Hawk' airfoil using arrays of jets during the gust process. Based on unsteady Navier-Stokes equations, the grid-velocity method is introduced to simulate the gust influence, and dynamic response in vertical gust flow perturbation is investigated for the airfoil as well. An unsteady surface transpiration boundary condition is enforced over a user specified portion of the airfoil’s surface to emulate the time dependent velocity boundary conditions. Firstly, after applying this method to simulate typical NACA0006 airfoil gust response to a step change in the angle of attack, it shows that the indicial responses of the airfoil make good agreement with the exact theoretical values and the calculated values in references. Furthermore, gust response characteristic for the quasi 'Global Hawk' airfoil is analyzed. Five kinds of flow control techniques are introduced as steady blowing, steady suction, unsteady blowing, unsteady suction and synthetic jets. The physical analysis of the influence on the effects of gust load alleviation is proposed to provide some guidelines for practice. Numerical results have indicated that active flow control technique,as a new technology of gust load alleviation, can affect and suppress the fluid disturbances caused by gust so as to achieve the purpose of gust load alleviation.XU Xiaoping ZHU Xiaoping ZHOU Zhou FAN Ruijun 2011Chinese Journal of Aeronautics2011,24,4:8
12Status and development of high-power laser facilities at the NLHPLP显示文摘In this paper, we review the status of the multifunctional experimental platform at the National Laboratory of High Power Laser and Physics(NLHPLP). The platform, including the SG-II laser facility, SG-II 9th beam, SG-II upgrade(SG-II UP) facility, and SG-II 5 PW facility, is operational and available for interested scientists studying inertial confinement fusion(ICF) and a broad range of high-energy-density physics. These facilities can provide important experimental capabilities by combining different pulse widths of nanosecond, picosecond, and femtosecond scales. In addition, the SG-II UP facility, consisting of a single petawatt system and an eight-beam nanosecond system, is introduced including several laser technologies that have been developed to ensure the performance of the facility. Recent developments of the SG-II 5 PW facility are also presented.Jianqiang Zhu Jian Zhu Xuechun Li Baoqiang Zhu Weixin Ma Xingqiang Lu Wei Fan Zhigang Liu Shenlei Zhou Guang Xu Guowen Zhang Xinglong Xie Lin Yang Jiangfeng Wang Xiaoping Ouyang Li Wang Dawei Li Pengqian Yang Quantang Fan Mingying Sun Chong Liu Dean Liu Yanli Zhang Hua Tao Meizhi Sun Ping Zhu Bingyan Wang Zhaoyang Jiao Lei Ren Daizhong Liu Xiang Jiao Hongbiao Huang Zunqi Lin 2018High Power Laser Science and Engineering2018,6,4:8
13SERK Receptor-like Kinases Control Division Patterns of Vascular Precursors and Ground Tissue Stem Cells during Embryo Development in Arabidopsis显示文摘During embryo development, the vascular precursors and ground tissue stem cells divide to renew them-selves and produce the vascular tissue, endodermal cells, and cortical cells. However, the molecular mech-anisms regulating division of these stem cells have remained largely elusive. In this study, we show that loss of function of SOMATIC EMBRYOGENESIS RECEPTOR-UKE KINASE (SERK) genes results in aberrant em-bryo development. Fewer cortical, endodermal, and vascular cells are generated in the embryos of serk1 serk2bak1 triple mutants. WUSCHEL-RELATED HOMBOBOX5 (WOXS) is ectopically expressed in vascular cells of serkl serk2 bak1 embryos. The first transverse division of vascular precursors in mid-globular em-bryos and second asymmetric division of ground tissue stem cells in early-heart embryos are abnormally altered to a longitudinal division. The embryo defects can be partially rescued by constitutively activated mitogen-activated protein kinase (MAPK) kinase kinase YODA (YDA) and MAPK kinase MKK5. Taken together, our results reveal that SERK-mediated signals regulate division patterns of vascular precursors and ground tissue stem cells, likely via the YDA-MKK4/5 cascade, during embryo development.Huiqiang Li Zeping Cai Xiaojuan Wang Meizhen Li Yanwei Cui Nan Cui Fei Yang Mingsong Zhu Junxiang Zhao Wenbin Du Kai He Jing Yi Frans E.Tax Suiwen Hou Jia Li Xiaoping Gou 2019Molecular Plant2019,12,7:7
14Field trial of an HTS filter system on a CDMA base station显示文摘This paper presents the field trial results of a high temperature superconductor filter system (HTSFS) in a code division multiple access (CDMA) mobile communication base station (BTS) in Tangshan, China. The center frequency of the HTSFS is 830 MHz with 1.4% fractional bandwidth. The noise figure (NF) of the HTSFS, including connectors and cables, is 0.8 dB. The field trial results show that after the HTSFS was installed in the receiver front-end of a CDMA base station, the transmitting power of handset was decreased by 3.1 dB on average. Up to now, the HTSFS has been running steadily in the base station for more than 22 months, demonstrating the reliability and stability of the system.YIN ZheSheng WEI Bin CAO BiSong WANG Xin GUO XuBo ZHANG XiaoPing GAO LongMa PIAO YunLong ZHU MaFeng LIANG Yong WANG Fan H.

15Disruption of MIR396e and MIR396f improves rice yield under nitrogen-deficient conditions显示文摘The microRNA miR396 directly represses GROWTH-REGULATING FACTORs(OsGRFs)and has been implicated in regulating rice yield and in nitrogen assimilation.Overexpressing the miR396 targets OsGRF4 and OsGRF6 improves rice yield via increased grain size and panicle branching,respectively.Here,we used CRISPR/Cas9 to assess the function of miR396 genes in rice.Knockout of MIR396 ef(MIR396e and MIR396f),but not other isoforms,enhanced both grain size and panicle branching,resulting in increased grain yield.Importantly,under nitrogen-deficient conditions,mir396ef mutants showed an even higher relative increase in grain yield as well as elevated above-ground biomass.Furthermore,we identified OsGRF8 as a new target of miR396,in addition to the known targets OsGRF4 and OsGRF6.Disruption of the miR396-targeting site in OsGRF8 was sufficient to both enlarge grain size and elongate panicles.Our results suggest that rice-seed and panicle development are regulated by miR396ef-GRF4/6/8-GIF1/2/3 modules and that mi R396ef are promising targets of genome editing for breeding environmentally friendly rice varieties that require less nitrogen fertilization.Jinshan Zhang Zhenyu Zhou Jinjuan Bai Xiaoping Tao Ling Wang Hui Zhang Jian-Kang Zhu 2020National Science Review2020,7,1:7

17Cross-cultural adaption and psychometric properties of the Chinese version of the Diabetes Behavior Rating Scale: a pilot study显示文摘Self-care behavior plays a major role in diabetic management. However, in China, a satisfactory instrument has not yet been developed to evaluate the compliance of self-care behavior for young patients with type 1 diabetes mellitus(T1 DM). The Diabetes Behavior Rating Scale(DBRS) has a potential to be the first mature instrument. The purpose of this study is to cross-culturally adapt the DBRS, and preliminarily evaluate its psychometric properties. The instrument translation included translation, back translation and culture adaptation. Psychometric properties were assessed in a sample of 116 young patients with T1 DM adapting insulin injection therapy. The Chinese version of the DBRS was divided to four subscales. Cronbach's α for the total scale was 0.92. The mean inter-item and item-total correlations were 0.35 and 0.54 respectively. Test-retest reliability showed good temporal stability(r=0.81, P=0.001). Negative correlations were found between DBRS scores with the Diabetes Distress Scale scores(r=.0.32, P=0.003) and hemoglobin A1 c(HbA1 c) levels(r=.0.36, P=0.002). Higher DBRS scores correlated with better glycemic control. The Chinese insulin injection therapy version of the DBRS is well translated and culturally adapted. It shows good overall reliability and validity and appears to be a valuable tool for assessing the diabetic self-care behaviors for young patients with T1 DM.Jing Zhu Jingjing Xu Yang Chen Yong Gu Li Ji Yufeng Zhou Min Zhu Hsiang-Ting Hsu Xiaoping Huang Cuiping Yuan Yun Shi Dan Yan Lili Xie Shuang Chen Tao Yang Wei He 2018Science China(Life Sciences)2018,61,3:6
18Study and application of temporal index technology显示文摘This paper addresses the mathematical relation on a set of periods and temporal indexing construc- tions as well as their applications. First we introduce two concepts, i.e. the temporal connection and temporal inclusion, which are equivalence relation and preorder relation respectively. Second, by study- ing some basic topics such as the division of 'large' equivalence classes and the overlaps of preorder relational sets, we propose a temporal data index model (TDIM) with a tree-structure consisting of a root node, equivalence class nodes and linearly ordered branch nodes. Third, we study algorithms for the temporal querying and incremental updating as well as dynamical management within the framework of TDIM. Based on a proper mathematical supporting, TDIM can be applied to researching some significant practical cases such as temporal relational and temporal XML data and so on.YE XiaoPing TANG Yong CHEN LuoWu GUO Huan ZHU Jun CHEN KaiYuan 2009Science in China(Series F)2009,52,6:6
19Physical sensors for skin-inspired electronics显示文摘Skin,the largest organ in the human body,is sensitive to external stimuli.In recent years,an increasing number of skin-inspired electronics,including wearable electronics,implantable electronics,and electronic skin,have been developed because of their broad applications in healthcare and robotics.Physical sensors are one of the key building blocks of skin-inspired electronics.Typical physical sensors include mechanical sensors,temperature sensors,humidity sensors,electrophysiological sensors,and so on.In this review,we systematically review the latest advances of skin-inspired mechanical sensors,temperature sensors,and humidity sensors.The working mechanisms,key materials,device structures,and performance of various physical sensors are summarized and discussed in detail.Their applications in health monitoring,human disease diagnosis and treatment,and intelligent robots are reviewed.In addition,several novel properties of skin-inspired physical sensors such as versatility,self-healability,and implantability are introduced.Finally,the existing challenges and future perspectives of physical sensors for practical applications are discussed and proposed.Shuo Li Yong Zhang Yiliang Wang Kailun Xia Zhe Yin Huimin Wang Mingchao Zhang Xiaoping Liang Haojie Lu Mengjia Zhu Haomin Wang Xinyi Shen Yingying Zhang 2020InfoMat2020,2,1:5
20Effect of cDNA fragments in different length derived from Potato Virus Y coat protein gene on the induction of RNA-mediated virus resistance显示文摘We have reported that cDNA derived from entire coat protein (CP) gene of potato virus Y (PVY) could induce resistance to PVY infection in transgenic tobacco plants, and the resistance was further demonstrated to be RNA-mediated rather than coat protein-mediated. In this study, we cloned cDNA fragments of 202 bp, 417 bp, and 603 bp in length derived from the 3′ end of the PVY CP gene, and the cDNA fragments were introduced into tobacco (var. NC89) plants via Agrobacterium-mediated transformation system. The results of resistance assay showed that the CP cDNA fragments of 417 bp and 603 bp could confer resistance of the trans-genic plants to PVY infection, but the fragment of 202 bp in length could not. Molecular analysis revealed that the resistance was RNA-mediated, which is believed to be a result of post-transcriptional gene silencing. The results indicate that the length of cDNA fragments needed for resistance induction was located somewhere between 202 bp and 417 bp from the 3′ end of PVY CP gene.ZHU Junhua ZHU Xiaoping WEN Fujiang BAI Qingrong ZHU Changxiang SONG Yunzhi 2004Science China(Life Sciences)2004,47,4:5
