| 1 | Generation of B Cell-Deficient Pigs by Highly Efficient CRISPR/Cas9-Mediated Gene Targeting显示文摘Generating B cell-deficient mutant is the first step to produce human antibody repertoires in large animal models. In this study, we applied the clustered regularly interspaced short palindromic repeat(CRISPR)/CRISPR-associated(Cas) system to target the JHregion of the pig Ig M heavy chain gene which is crucial for B cell development and differentiation. Transfection of Ig M-targeting Cas9 plasmid in primary porcine fetal fibroblasts(PFFs) enabled inducing gene knock out(KO) in up to 53.3% of colonies analyzed, a quarter of which harbored biallelic modification, which was much higher than that of the traditional homologous recombination(HR). With the aid of somatic cell nuclear transfer(SCNT) technology, three piglets with the biallelic Ig M heavy chain gene mutation were produced. The piglets showed no antibody-producing B cells which indicated that the biallelic mutation of the Ig M heavy chain gene effectively knocked out the function of the Ig M and resulted in a B cell-deficient phenotype. Our study suggests that the CRISPR/Cas9 system combined with SCNT technology is an efficient genome-editing approach in pigs. | Fengjiao Chen Ying Wang Yilin Yuan Wei Zhang Zijian Ren Yong Jin Xiaorui Liu Qiang Xiong Qin Chen Manling Zhang Xiaokang Li Lihua Zhao Ze Li Zhaoqiang Wu Yanfei Zhang Feifei Hu Juan Huang Rongfeng Li Yifan Dai | 2015 | Journal of Genetics and Genomics2015,42,8: | 15 |
| 2 | Carbon decorated Li_(3)V_(2)(PO_(4))_(3) for high-rate lithium-ion batteries:Electrochemical performance and charge compensation mechanism显示文摘Fast charging and high-power delivering batteries are highly demanded in mobile electronics,electric vehicles and grid energy storage,but there are full of challenges.The star-material Li_(3)V_(2)(PO_(4))_(3) is demonstrated as a promising high-rate cathode material meeting the above requirements.Herein,we report the carbon decorated Li_(3)V_(2)(PO_(4))_(3) (LVP/C) cathode prepared via a facile method,which displays a remarkable high-rate capability and long-term cycling performance.Briefly,the prepared LVP/C delivers a high discharge capacity of 122 mAh g^(-1)(-93% of the theoretical capacity) at a high rate up to 20 C and a superior capacity retention of 87.1% after 1000 cycles.Importantly,by applying a combination of X-ray absorption spectroscopy and full-range mapping of resonant inelastic X-ray scattering,we clearly elucidate the structural and chemical evolutions of LVP upon various potentials and cycle numbers.We show unambiguous spectroscopic evidences that the evolution of the hybridization strength between V and O in LVP/C as a consequence of lithiation/delithiation is highly reversible both in the bulk and on the surface during the discharge-charge processes even over extended cycles,which should be responsible for the remarkable electrochemical performance of LVP/C.Our present study provides not only an effective synthesis strategy but also deeper insights into the surface and bulk electrochemical reaction mechanism of LVP,which should be beneficial for the further design of high-performance LVP electrode materials. | Manling Ding Chen Cheng Qiulong Wei Yue Hu Yingying Yan Kehua Dai Jing Mao Jinghua Guo Liang Zhang Liqiang Maig | 2021 | Journal of Energy Chemistry2021,30,2: | 3 |
| 3 | Overexpressing dominant-negative FGFR2-IIIb impedes lung branching morphogenesis in pigs显示文摘Genetic studies with mouse models have shown that fibroblast growth factor receptor 2-IIIb(FGFR2-IIIb)plays crucial roles in lung development and differentiation. To evaluate the effect of FGFR2-IIIb in pig lung development, we employed somatic cell nuclear transfer(SCNT) technology to generate transgenic pig fetuses overexpressing the transmembrane(dn FGFR2-IIIb-Tm) and soluble(dn FGFR2-IIIb-HFc) forms of the dominant-negative human FGFR2-IIIb driven by the human surfactant protein C(SP-C) promoter,which was specifically expressed in lung epithelia. Eight dn FGFR2-IIIb-Tm transgenic and twelve dn FGFR2-IIIb-HFc transgenic pig fetuses were collected from three and two recipient sows, respectively.Repression of FGFR2-IIIb in lung epithelia resulted in smaller lobes and retardation of alveolarization in both forms of dn FGFR2-IIIb transgenic fetuses. Moreover, the dn FGFR2-IIIb-HFc transgenic ones showed more deterioration in lung development. Our results demonstrate that disruption of FGFR2-IIIb signaling in the epithelium impedes normal branching and alveolarization in pig lungs, which is less severe than the results observed in transgenic mice. The dn FGFR2-IIIb transgenic pig is a good model for the studies of blastocyst complementation as well as the mechanisms of lung development and organogenesis. | Qin Chen Bin Fang Ying Wang Chu Li Xiaoxue Li Ronggen Wang Qiang Xiong Lining Zhang Yong Jin Manling Zhang Xiaorui Liu Lin Li Lisha Mou Rongfeng Li Haiyuan Yang Yifan Dai | 2018 | Journal of Genetics and Genomics2018,45,3: | 2 |
| 4 | Precipitate-stabilized surface enabling high-performance Na_(0.67)Ni_(0.33-x)Mn_(0.67)Zn_(x)O_(2) for sodium-ion battery显示文摘Electrode interfacial degradations are the key challenges for high-performance rechargeable batteries,usually mitigated through surface modification/coating strategies.Herein,we report a novel mechanism to enhance the surface stability of P2 layered cathodes by introducing a high density of dopant-enriched precipitates.Based on microscopic analysis,we show that forming a high density of precipitates at the grain surface can effectively suppress surface cracking and corrosion,which not only improves the surface/interface stability but also effectively suppresses the intergranular cracking issue.Increasing the doping level can lead to a greater density of precipitates at the surface region,which results in higher surface stability and increased cycling stability of the P2 layered cathode for a sodium-ion battery.We further reveal that prolonged cycling can induce the formation of a precipitate-free surface region due to the loss of Zn dopant and Na.Our in-depth microanalysis reveals cycling-induced dynamic structural evolution of the P2 layered cathodes,highlighting that dopant segregation-induced precipitation is a new approach to achieving high interfacial stability. | Kuan Wang Zhengfeng Zhang Sulan Cheng Xiao Han Junjie Fu Manling Sui Pengfei Yan | 2022 | eScience2022,2,5: | 2 |
| 5 | Poaceae Orthologs of Rice OsSGL,DUF1645 Domain-Containing Genes,Positively Regulate Drought Tolerance,Grain Length and Weight in Rice显示文摘Grain yield is a polygenic trait that can be influenced by environmental factors and genetic compositions at all plant growth stages.Currently,the molecular mechanisms behind the coordination of the interaction between grain yield-related traits remain unknown.In this study,we characterized the function of four STRESS_tolerance and GRAIN_LENGTH(Os SGL)Poaceae ortholog genes that are transcribed into DUF1645 domain-containing proteins in relation to the grain length,grain weight,and drought stress-tolerance of rice.The transgenic plants with overexpressing or heterologous high levels of Poaceae OsSGL ortholog genes exhibited longer grain size than the wild type plants.Larger cells were seen in panicles of the four transgenic lines with paraffin sectioning and scanning electron microscopy analyses.In addition,four Poaceae OsSGL ortholog genes positively affected the drought tolerance of rice.Four transgenic plants displayed higher resistance to drought stress at the seedling and vegetative stages.RNA-sequencing and qRT-PCR results indicated that over-or heterologous-expression of four Poaceae OsSGL ortholog genes also affected the transcriptome of rice plants.These genes may play a role in auxin and cytokinin biosynthesis and their transduction pathways.Taken together,these results suggested that the four OsSGL orthologs have a conserved function in the regulation of stress-tolerance and cell growth by modulating hormonal biosynthesis and signaling. | LIU Kai LI Minjuan ZHANG Bin YIN Xuming XIA Xinjie WANG Manling CUI Yanchun | 2022 | Rice science2022,29,3: | 2 |

| 8 | Protection of ±500 kV HVDC Double-circuit Converter Station from Lightning Induced Overvoltage显示文摘In order to obtain reasonable schemes of arrester in converter stations, the arrester scheme of 'Xiluodu-Guangdong HVDC ± 500 kV double circuit transmission' project against lighting induced overvoltage, which was designed according to the main principle of lightning protection in converter station, is discussed. A calculation of the lighting induced overvoltage in Zhaotong converter station un- der various operation modes is performed with ATP-EMTP software, then the surge arrester configuration of the converter station is decided, and the arrester protection schemes of smoothing reactor and neutral line are studied. It is concluded that additional protection is necessary because of the relatively large gap between protected disconnecting switch and arrester of metallic return transfer bus. Plus, the smoothing reactor (SR) arrester near the valve hall could be removed to improve the scheme’s economic performance. | DONG Manling YUAN Zhiyong LI Tianwei ZHAO Xiangen ZHANG Jiaxin HE Junjia | 2013 | 高电压技术2013,39,8: | 1 |
| 9 | Investigation of the microcrack evolution in a Ti-based bulk metallic glass matrix composite显示文摘The initiation and evolution behavior of the shear-bands and microcracks in a Ti-based metallic-glass–matrix composite(MGMC) were investigated by using an in-situ tensile test under transmission electron microscopy(TEM). It was found that the plastic deformation of the Ti-based MGMC related with the generation of the plastic deformation zone in crystalline and shear deformation zone in glass phase near the crack tip. The dendrites can suppress the propagation of the shear band effectively. Before the rapid propagation of cracks, the extending of plastic deformation zone and shear deformation zone ahead of crack tip is the main pattern in the composite. | Yongsheng Wang Zhenxi Guo Rui Ma Guojian Hao Yong Zhang Junpin Lin Manling Sui | 2014 | Progress in Natural Science:Materials International2014,24,2: | 1 |
| 10 | Factors in?uencing the somatic cell nuclear transfer ef?ciency in pigs显示文摘Using a data set from our laboratory, we assessed the effects of several factors on pig cloning ef?ciency. The results demonstrated that cells at high con?uence( > 90%) used as donor cell resulted in higher pregnancy rate, delivery rate and overall cloning ef?ciency(number of live offspring born per reconstructed embryo transferred to recipients) compared with the cells at 60% to79% con?uence and 80% to 89% con?uence. Cells with four, ?ve and six passages compromised the pregnancy and delivery rates compared with ?rst passage cells. The number of blastocysts transferred by somatic cell nuclear transfer(SCNT) did not signi?cantly affect the cloning ef?ciency, but transfer of blastocyst derived from in vitro culture 5 d after SCNT achieved a signi?cantly higher pregnancy rate compared with one to two cell SCNT embryos from overnight culture. The highest pregnancy rate, delivery rate and the largest litter size were obtained when Bama Miniature pig ?broblasts were used as donor cells and Landrace/Yorkshire hybrid gilts were used as recipients. Recipients treated with chemicals for estrus synchronization had higher pregnancy rates compared with untreated recipients. Our data might be helpful for improving SCNT ef?ciency in pigs. | Yong JIN Manling ZHANG Xinrong JU Shuang LIANG Qiang XIONG Lihua ZHAO Xiaowei NIE Daorong HOU Qiang LIU Junzheng WANG Chenyu WANG Xiaokang LI Lining ZHANG Xiaorui LIU Ying WANG Haiyuan YANG Yifan DAI Rongfeng LI | 2019 | Frontiers of Agricultural Science and Engineering2019,6,1: | 0 |

| 12 | Deciphering the critical effect of cathode-electrolyte interphase by revealing its dynamic evolution显示文摘Cathode electrolyte interphase(CEI)layer plays a crucial role in determining the electrochemical performance of lithium-ion batteries.Limited by the sensitive nature of CEI and the lack of characterization techniques,its dynamic evolution during cycling,its formation mechanism,and its specific impact on battery performance are not yet fully understood.Herein,we systematically investigate the dynamic evolution of CEI layer and its critical effect on the cycling performance of LiCoO_(2)cathode by diverse characterization techniques.We find that cycling voltage plays a key role in affecting CEI formation and evolution,and a critical potential(4.05 V vs.Li)is identified,which acts as the switching potential between CEI deposition and decomposition.We show that CEI starts deposition in the discharge process when the potential is below 4.05 V,and CEI decomposition occurs when the potential is higher than 4.05 V.When the battery is cycled below such a critical potential,a stable CEI layer is developed,which leads to superior cycling stability.When the battery is cycled above such a critical potential,a CEI-free cathode interface is observed,which also demonstrates good cycle stability.However,when the critical potential falls in the cycling voltage range,CEI deposition and decomposition are repeatedly switched on during cycling,leading to the dynamically unstable CEI layer.The unstable CEI layer causes continuous interfacial reaction and degradation,resulting in battery performance decay.Our work deepens the understanding of the CEI formation and evolution mechanisms,and clarifies the critical effect of CEI layer on cycling performance,which provides new insights into stabilizing the electrode-electrolyte interface for high-performance rechargeable batteries. | Zhengfeng Zhang Changdong Qin Kuan Wang Xiao Han Jinhui Li Manling Sui Pengfei Yan | 2023 | Journal of Energy Chemistry2023,,6: | 0 |
