1OTUD5 promotes innate antiviral and antitumor immunity through deubiquitinating and stabilizing STING显示文摘Stimulator of interferon genes(STING)is an adaptor protein that is critical for effective innate antiviral and antitumor immunity.The activity of STING is heavily regulated by protein ubiquitination,which is fine-tuned by both E3 ubiquitin ligases and deubiquitinases.Here,we report that the deubiquitinase OTUD5 interacts with STING,cleaves its K48-linked polyubiquitin chains,and promotes its stability.Consistently,knockout of OTUD5 resulted in faster turnover of STING and subsequently impaired type I IFN signaling following cytosolic DNA stimulation.More importantly,Lyz2-Cre Otud5^(fl/Y) mice and CD11-Cre Otud5^(fl/Y) mice showed more susceptibility to herpes simplex virus type 1(HSV-1)infection and faster development of melanomas than their corresponding control littermates,indicating that OTUD5 is indispensable for STING-mediated antiviral and antitumor immunity.Our data suggest that OTUD5 is a novel checkpoint in the cGAS-STING cytosolic DNA sensing pathway.Yunyun Guo Fei Jiang Lingli Kong Haifeng Wu Honghai Zhang Xiaorong Chen Jian Zhao Baoshan Cai Yanqi Li Chunhong Ma Fan Yi Lei Zhang Bingyu Liu Yi Zheng Lingqiang Zhang Chengjiang Gao 2021Cellular & Molecular Immunology2021,18,8:2

3Development of low-coherence high-power laser drivers for inertial confinement fusion显示文摘The use of low-coherence light is expected to be one of the effective ways to suppress or even eliminate the laser–plasma instabilities that arise in attempts to achieve inertial confinement fusion.In this paper,a review of low-coherence high-power laser drivers and related key techniques is first presented.Work at typical low-coherence laser facilities,including Gekko XII,PHEBUS,Pharos III,and Kanal-2 is described.The many key techniques that are used in the research and development of low-coherence laser drivers are described and analyzed,including low-coherence source generation,amplification,harmonic conversion,and beam smoothing of low-coherence light.Then,recent progress achieved by our group in research on a broadband low-coherence laser driver is presented.During the development of our low-coherence high-power laser facility,we have proposed and implemented many key techniques for working with low-coherence light,including source generation,efficient amplification and propagation,harmonic conversion,beam smoothing,and precise beam control.Based on a series of technological breakthroughs,a kilojoule low-coherence laser driver named Kunwu with a coherence time of only 300 fs has been built,and the first round of physical experiments has been completed.This high-power laser facility provides not only a demonstration and verification platform for key techniques and system integration of a low-coherence laser driver,but also a new type of experimental platform for research into,for example,high-energy-density physics and,in particular,laser–plasma interactions.Yanqi Gao Yong Cui Lailin Ji Daxing Rao Xiaohui Zhao Fujian Li Dong Liu Wei Feng Lan Xia Jiani Liu Haitao Shi Pengyuan Du Jia Liu Xiaoli Li Tao Wang Tianxiong Zhang Chong Shan Yilin Hua Weixin Ma Xun Sun Xianfeng Chen Xiuguang Huang Jian Zhu Wenbing Pei Zhan Sui Sizu Fu 2020Matter and Radiation at Extremes2020,5,6:1

6Interactions between Pre-strain and Dislocation Structures and Its Effect on the Hydrogen Trapping Behaviors显示文摘This work investigated the effect of pre-strain and microstructures and their interactions on hydrogen trapping behaviors in case of 1-GPa high-strength martensitic steel Fe-0.05C-0.30Si-1.10Mn-3.50Ni-0.53Cr-0.50Mo-0.03 V(wt%).We found that the trapped reversible and trapped irreversible hydrogen contents increased significantly after applying a pre-strain of 5%,with an increase in the trapped reversible hydrogen content from 0.6 ppm in the original sample to 2.1 ppm.The hydrogen desorption activation energy also showed a slight increase.The microstructural evolution revealed that the concomitant dislocation cell-twin duplex microstructure with high-density tangled dislocations after pre-strain substantially increased the trapped reversible hydrogen contents.Additionally,the tangled dislocations pinned by the nanoprecipitates acted as deep irreversible hydrogen traps,increasing the trapped hydrogen at high temperatures after applying 5%pre-strain.These findings provide an expanded understanding of the hydrogen trapping behaviors of pre-strained microstructures.Rongjian Shi Yanqi Tu Liang Yang Saiyu Liu Shani Yang Kewei Gao Xu-Sheng Yang Xiaolu Pang 2023Acta Metallurgica Sinica(English Letters)2023,36,7:0
7Enhancing the photoelectrochemical performance of p-silicon through TiO_(2)coating decorated with mesoporous MoS_(2)显示文摘MoS_(2)is a promising electrocatalyst for hydrogen evolution reaction and a good candidate for cocatalyst to enhance the photoelectrochemical(PEC)performance of Si-based photoelectrode in aqueous electrolytes.The main challenge lies in the optimization of the microstructure of MoS_(2),to improve its catalytic activity and to construct a mechanically and chemically stable cocatalyst/Si photocathode.In this paper,a highly-ordered mesoporous MoS_(2)was synthesized and decorated onto a TiO_(2)protected p-silicon substrate.An additional TiO_(2)necking was introduced to strengthen the bonding between the MoS_(2)particles and the TiO_(2)layer.This meso-MoS_(2)/TiO_(2)/p-Si hybrid photocathode exhibited significantly enhanced PEC performance,where an onset potential of+0.06 V(versus RHE)and a current density of-1.8 mA/cm^(2)at 0 V(versus RHE)with a Faradaic efficiency close to 100%was achieved in 0.5 mol/L H_(2)SO_(4).Additionally,this meso-MoS_(2)/TiO_(2)/p-Si photocathode showed an excellent PEC ability and durability in alkaline media.This paper provides a promising strategy to enhance and protect the photocathode through high-performance surface cocatalysts.Hongmei WU Feng LI Yanqi YUAN Jing LIU Liping ZHAO Peng ZHANG Lian GAO 2021Frontiers in Energy2021,15,3:0
8Dexmedetomidine alleviates oxygen and glucose deprivation-induced apoptosis in mesenchymal stem cell via downregulation of MKP-1显示文摘Bone marrow mesenchymal stem cell(MSC)-based therapy is a novel candidate for heart repair.But ischemiareperfusion injury leads to low viability of MSC.Dexmedetomidine(Dex)has been found to protect neurons against ischemia-reperfusion injury.It remains unknown if Dex could increase the viability of MSCs under ischemia.The present study is to observe the potential protective effect of Dex on MSCs under ischemia and its underlying mechanisms.Specific mRNAs related to myocardial ischemia in the GEO database were selected from the mRNA profiles assessed in a previous study using microarray.The most dysregulated mRNAs of the specific ones from the above study were subject to bioinformatics analysis at our laboratory.These dysregulated mRNAs possibly regulated apoptosis of cardiomyocytes and were validated in vitro for their protective effect on MSCs under ischemia.MSCs were pre-treated with Dex at 10μM concentration for 24 h under oxygen-glucose deprivation(OGD).Flow cytometry and TUNEL assay were carried out to detect apoptosis in Dex-pretreated MSCs under OGD.The relative expressions of mitogen-activated protein kinase phosphatase 1(MKP-1)and related genes were detected by quantitative polymerase chain reaction and western blotting.Microarray data analysis revealed that Dex regulates MAPK phosphatase activity.Dex significantly reduced in vitro apoptosis of MSCs under OGD,which suppressed the synthesis level of Beclin1 and light chain 3 proteins.Dex down-regulated MKP-1 expression and attenuated an OGDinduced change in the mitogen activated protein kinase 3(MAPK3)signaling pathway.Dex increases the viability of MSC and improves its tolerance to OGD in association with the MKP-1 signaling pathway,thus suggesting the potential of Dex as a novel strategy for promoting MSCs efficacy under ischemia.RUICONG GUAN KUAN ZENG MINNAN GAO JIANFEN LI HUIQI JIANG LU ZHANG JINGWEN LI BIN ZHANG YUQIANG LIU ZHUXUAN LIU DIAN WANG YANQI YANG 2022BIOCELL2022,46,11:0
9Research on Optimal Configuration of Energy Storage in Wind-Solar Microgrid Considering Real-Time Electricity Price显示文摘Capacity allocation and energy management strategies for energy storage are critical to the safety and economical operation of microgrids.In this paper,an improved energymanagement strategy based on real-time electricity price combined with state of charge is proposed to optimize the economic operation of wind and solar microgrids,and the optimal allocation of energy storage capacity is carried out by using this strategy.Firstly,the structure and model of microgrid are analyzed,and the outputmodel of wind power,photovoltaic and energy storage is established.Then,considering the interactive power cost between the microgrid and the main grid and the charge-discharge penalty cost of energy storage,an optimization objective function is established,and an improved energy management strategy is proposed on this basis.Finally,a physicalmodel is built inMATLAB/Simulink for simulation verification,and the energy management strategy is compared and analyzed on sunny and rainy days.The initial configuration cost function of energy storage is added to optimize the allocation of energy storage capacity.The simulation results show that the improved energy management strategy can make the battery charge-discharge response to real-time electricity price and state of charge better than the traditional strategy on sunny or rainy days,reduce the interactive power cost between the microgrid system and the power grid.After analyzing the change of energy storage power with cost,we obtain the best energy storage capacity and energy storage power.Zhenzhen Zhang Qingquan Lv Long Zhao Qiang Zhou Pengfei Gao Yanqi Zhang Yimin Li 2023Energy Engineering2023,120,7:0
10Backward scattering of laser plasma interactions from hundreds-of-joules broadband laser on thick target显示文摘The use of broadband laser technology is a novel approach for inhibiting processes related to laser plasma interactions(LPIs).In this study,several preliminary experiments into broadband-laser-driven LPIs are carried out using a newly established hundreds-of-joules broadband second-harmonic-generation laser facility.Through direct comparison with LPI results for a traditional narrowband laser,the actual LPI-suppression effect of the broadband laser is shown.The broadband laser had a clear suppressive effect on both back-stimulated Raman scattering and back-stimulated Brillouin scattering at laser intensities below 1×10^(15) W cm^(−2).An abnormal hot-electron phenomenon is also investigated,using targets of different thicknesses.Peipei Wang Honghai An Zhiheng Fang Jun Xiong Zhiyong Xie Chen Wang Zhiyu He Guo Jia Ruirong Wang Shu Zheng Lan Xia Wei Feng Haitao Shi Wei Wang Jinren Sun Yanqi Gao Sizu Fu 2024Matter and Radiation at Extremes2024,9,1:0
