| 4 | Evolution and Domestication Footprints Uncovered from the Genomes of Coix显示文摘Coix lacryma-jobi,a plant species closely related to Zea and Sorghum,is an important food and medicinal crop in Asia.However,no reference genome of this species has been reported,and its exact phylogeny within the Andropogoneae remains unresolved.Here,we generated a high-quality genome assembly of coix comprising~1.73 Gb with 44485 predicted protein-coding genes.We found coix to be a typical diploid plant with an overall 1-to-1 syntenic relationship with the Sorghum genome,despite its drastic genome expansion(~2.3-fold)due mainly to the activity of transposable elements.Phylogenetic analysis revealed that coix diverged with sorghum~10.41 million years ago,which was~1.49 million years later than the divergence between sorghum and maize.Resequencing of 27 additional coix accessions revealed that they could be unambiguously separated into wild relatives and cultivars,and suggested that coix experienced a strong genetic bottleneck,resulting in the loss of about half of the genetic diversity during domestication,even though many traits have remained undomesticated.Our data not only provide novel comparative genomic and evolutionary insights into the Andropogoneae lineage,but also an important resource that will greatly benefit molecular breeding of this important crop. | Hongbing Liu Junpeng Shi Zexi Cai Yumin Huang Menglu Lv Huilong Du Qiang Gao Yi Zuo Zhaobin Dong Wei Huang Rui Qin Chengzhi Liang Jinsheng Lai Weiwei Jin | 2020 | Molecular Plant2020，13，2： | 4 |
| 5 | Nano-crystalline FeOOH mixed with SWNT matrix as a superior anode material for lithium batteries显示文摘Nano-crystalline FeOOH particles(5~10 nm) have been uniformly mixed with electric matrix of single-walled carbon nanotubes(SWNTs)for forming FeOOH/SWNT composite via a facile ultrasonication method. Directly using the FeOOH/SWNT composite(containing 15 wt%SWNTs) as anode material for lithium battery enhances kinetics of the Li+insertion/extraction processes, thereby effectively improving reversible capacity and cycle performance, which delivers a high reversible capacity of 758 mAh g-1under a current density of 400 mA g-1even after 180 cycles, being comparable with previous reports in terms of electrochemical performance for FeOOH anode. The good electrochemical performance should be ascribed to the small particle size and nano-crystalline of FeOOH, as well as the good electronic conductivity of SWNT matrix. | Mingzhong Zou Weiwei Wen Jiaxin Li Yingbin Lin Heng Lai Zhigao Huang | 2014 | Journal of Energy Chemistry2014，23，4： | 3 |
| 6 | SnO_2 nanospheres among GO and SWNTs networks as anode for enhanced lithium storage performances显示文摘Conducting supporters of purified single-walled carbon nanotubes(SWNTs) and graphene oxide(GO)were used to confine pomegranate-structured Sn O2 nanospheres for forming SnO_2-GO-SWNT composites.As anode material for lithium ion batteries(LIBs), this composite exhibits a stable and large reversible capacity together with an excellent rate capability. In addition, an analysis of the AC impedance spectroscopy has been used to confirm the enhanced mechanism for LIB performance. The improved electrochemical performance should be ascribed greatly to the reinforced synergistic effects between GO and SWNT networks, and their enhanced contribution of the conductivity. These results indicate that this composite has potential for utilization in high-rate and durable LIBs. | Weiwei Wen Mingzhong Zou Qian Feng Jiaxin Li Heng Lai Zhigao Huang | 2016 | Journal of Energy Chemistry2016，25，3： | 2 |
| 7 | Degradation of metronidazole by dielectric barrier discharge in an aqueous solution显示文摘Degradation of metronidazole (MNZ) which is a representative and stable antibiotic by dielectric barrier discharge (DBD) in an aqueous solution has been studied. Effects of initial MNZ concentration, solution pH and coexisting organics on the degradation were investigated. The results illustrated that increasing the input power and the discharge frequency can improve the removal of MNZ. At low initial concentration, the removal of MNZ can reach up to 99.1%. Acidic and neutral conditions are more favorable for MNZ removal than alkaline condition in the early stage of degradation. However, the difference in MNZ removal between those in acidic or neutral media and that in alkaline one could be neglected with prolonging of the treatment time. Therefore, this method can be applied to MNZ degradation with a wide pH range. Coexisting organic matter in water can attenuate the removal to some extent. This study could provide valuable references for the degradation of nitroimidazole antibiotics by DBD. | Zhipeng Yang Anxing Lai Hangyu Chen Youxiang Yan Ye Yang Weiwei Zhang Lei Wang | 2019 | Frontiers of Environmental Science & Engineering2019，13，3： | 1 |
| 8 | Dynamic phenotypic heterogeneity and the evolution of multiple RNA subtypes in hepatocellular carcinoma:the PLANET study显示文摘Intra-tumor heterogeneity(ITH) is a key challenge in cancer treatment, but previous studies have focused mainly on the genomic alterations without exploring phenotypic(transcriptomic and immune)heterogeneity. Using one of the largest prospective surgical cohorts for hepatocellular carcinoma(HCC)with multi-region sampling, we sequenced whole genomes and paired transcriptomes from 67 HCC patients(331 samples). We found that while genomic ITH was rather constant across stages, phenotypic ITH had a very different trajectory and quickly diversified in stage Ⅱ patients. Most strikingly, 30% of patients were found to contain more than one transcriptomic subtype within a single tumor. Such phenotypic ITH was found to be much more informative in predicting patient survival than genomic ITH and explains the poor efficacy of single-target systemic therapies in HCC. Taken together, we not only revealed an unprecedentedly dynamic landscape of phenotypic heterogeneity in HCC, but also highlighted the importance of studying phenotypic evolution across cancer types. | Weiwei Zhai Hannah Lai Neslihan Arife Kaya Jianbin Chen Hechuan Yang Bingxin Lu Jia Qi Lim Siming Ma Sin Chi Chew Khi Pin Chua Jacob Josiah Santiago Alvarez Pauline Jieqi Chen Mei Mei Chang Lingyan Wu Brian K.P.Goh Alexander Yaw-Fui Chung Chung Yip Chan Peng Chung Cheow Ser Yee Lee Juinn Huar Kam Alfred Wei-Chieh Kow Iyer Shridhar Ganpathi Rawisak Chanwat Jidapa Thammasiri Boon Koon Yoong Diana Bee-Lan Ong Vanessa H.de Villa Rouchelle D.Dela Cruz Tracy Jiezhen Loh Wei Keat Wan Zeng Zeng Anders Jacobsen Skanderup Yin Huei Pang Krishnakumar Madhavan Tony Kiat-Hon Lim Glenn Bonney Wei Qiang Leow Valerie Chew Yock Young Dan Wai Leong Tam Han Chong Toh Roger Sik-Yin Foo Pierce Kah-Hoe Chow | 2022 | National Science Review2022，9，3： | 1 |

| 10 | BGB-A445,a novel non-ligand-blocking agonistic anti-OX40 antibody,exhibits superior immune activation and antitumor effects in preclinical models显示文摘t OX40 is a costimulatory receptor that is expressed primarily on activated CD4+,CD8+,and regulatory T cells.The ligation of OX40 to its sole ligand OX40L potentiates T cell expansion,differentiation,and activation and also promotes dendritic cells to mature to enhance their cytokine production.Therefore,the use of agonistic anti-Ox40 antibodies for cancer immunotherapy has gained great interest.However,most of the agonistic anti-OX40 antibodies in the clinic are OX40L-competitive and show limited efficacy.Here,we discovered that BGB-A445,a non-ligand-competitive agonistic anti-OX40 antibody currently under clinical investigation,induced optimal T cell activation without impairing dendritic cell function.In addition,BGB-A445 dose-dependently and significantly depleted regulatory T cells in vitro and in vivo via antibody-dependent cellular cytotoxicity.In the MC38 syngeneic model established in humanized OX40 knock-in mice,BGB-A445 demonstrated robust and dose-dependent antitumor efficacy,whereas the ligand-competitive anti-Ox40 antibody showed antitumor efficacy characterized by a hook effect.Furthermore,BGB-A445 demonstrated a strong combination antitumor effect with an anti-PD-1 antibody.Taken together,our findings show that BGB-A445,which does not block OX40-OX40L interaction in contrast to clinical-stage anti-OX40 antibodies,shows superior immune-stimulating effects and antitumor efficacy and thus warrants further clinical investigation. | Beibei Jiang Tong Zhang Minjuan Deng Wei Jin Yuan Hong Xiaotong Chen Xin Chen Jing Wang Hongjia Hou Yajuan Gao Wenfeng Gong Xing Wang Haiying Li Xiaosui Zhou Yingcai Feng Bo Zhang Bin Jiang Xueping Lu Lijie Zhang Yang Li Weiwei Song Hanzi Sun Zuobai Wang Xiaomin Song Zhirong Shen Xuesong Liu Kang Li Lai Wangl Ye Liu | 2023 | Frontiers of Medicine2023，17，6： | 0 |
| 11 | Simulation and experiment of vortex transport properties in a Type Ⅱ superconductor with grain boundary显示文摘We firstly described a simulation model to investigate the influence of grain boundary(GB)on the vortex transport properties in YBCO film.It is found that the size of inhomogeneous area caused by GB as well as the average velocity in transverse and longitudinal directions shows an angular dependence when the angle between the GB and the sample edge varies.We have also studied the impact of magnetic field intensity on dynamic behavior of vortex lattice and found that a lower vortex density makes it difficult for the vortex lattice to transfer from pinning state to flow state.As the magnetic field is decreased beyond a critical value,sharp jumps and strong fluctuations were observed in the I-V curve.Finally,we conducted measurements on a thin film YBa2Cu3O7 with an individual artificial grain boundary to support the simulation process. | JIANG Lai XU WeiWei HUA Tao YU Mei AN DeYue CHEN Jian JIN BiaoBing KANG Lin WU PeiHeng | 2015 | Science China(Technological Sciences)2015，58，3： | 0 |
| 12 | The cross-talk between methylation and phosphorylation in lymphoid-specific helicase drives cancer stem-like properties显示文摘Posttranslational modifications(PTMs)of proteins,including chromatin modifiers,play crucial roles in the dynamic alteration of various protein properties and functions including stem-cell properties.However,the roles of Lymphoid-specific helicase(LSH),a DNA methylation modifier,in modulating stem-like properties in cancer are still not clearly clarified.Therefore,exploring PTMs modulation of LSH activity will be of great significance to further understand the function and activity of LSH.Here,we demonstrate that LSH is capable to undergo PTMs,including methylation and phosphorylation.The arginine methyltransferase PRMT5 can methylate LSH at R309 residue,meanwhile,LSH could as well be phosphorylated by MAPK1 kinase at S503 residue.We further show that the accumulation of phosphorylation of LSH at S503 site exhibits downregulation of LSH methylation at R309 residue,which eventually promoting stem-like properties in lung cancer.Whereas,phosphorylation-deficient LSH S503A mutant promotes the accumulation of LSH methylation at R309 residue and attenuates stem-like properties,indicating the critical roles of LSH PTMs in modulating stem-like properties.Thus,our study highlights the importance of the crosstalk between LSH PTMs in determining its activity and function in lung cancer stem-cell maintenance. | Na Liu Rui Yang Ying Shi Ling Chen Yating Liu Zuli Wang Shouping Liu Lianlian Ouyang Haiyan Wang Weiwei Lai Chao Mao Min Wang Yan Cheng Shuang Liu Xiang Wang Hu Zhou Ya Cao Desheng Xiao Yongguang Tao | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 0 |
| 13 | GPR162 activates STING dependent DNA damage pathway as a novel tumor suppressor and radiation sensitizer显示文摘In the treatment of most malignancies,radiotherapy plays a significant role.However,the resistance of cancer cells to ionizing radiation(IR)is the main reason for the failure of radiotherapy,which causes tumor recurrence and metastasis.In this study,we confirmed that GPR162,an orphan receptor in the G-protein-coupled receptor family,acted as a novel radiotherapy sensitizer by interacting with the stimulator of interferon genes(STING),which targeted DNA damage responses,activated IRF3,accelerated the activation of type I interferon system,promoted the expression of chemokines including CXCL10 and CXCL4,and inhibited the occurrence and development of tumors.Interestingly,the activation of STING by overexpression of GPR162 was independent of the classical pathway of cGAS.STING inhibitors could resist the antitumor effect of overexpression of GPR162 in IR-induced mouse models.In addition,most solid tumors showed low expression of GPR162.And the higher expression of GPR162 indicated a better prognosis in patients with lung adenocarcinoma,liver cancer,breast cancer,etc.In summary,these results suggested that GPR162 may serve as a potential sensitizer of radiotherapy by promoting radiotherapy-induced STING-IFN production and increasing the expression of chemokines including CXCL10 and CXCL4 in DNA damage response,providing an alternative strategy for improving cancer radiotherapy. | Yao Long Jiaxing Guo Jielin Chen Jingyue Sun Haiyan Wang Xin Peng Zuli Wang WeiWei Lai Na Liu Long Shu Ling Chen Ying Shi Desheng Xiao Shuang Liu Yongguang Tao | 2023 | Signal Transduction and Targeted Therapy2023，8，3： | 0 |
| 14 | Highly Thermally Conductive and Structurally Ultra‑Stable Graphitic Films with Seamless Heterointerfaces for Extreme Thermal Management显示文摘Highly thermally conductive graphitic film(GF)materials have become a competitive solution for the thermal management of high-power electronic devices.However,their catastrophic structural failure under extreme alternating thermal/cold shock poses a significant challenge to reliability and safety.Here,we present the first investigation into the structural failure mechanism of GF during cyclic liquid nitrogen shocks(LNS),which reveals a bubbling process characterized by“permeation-diffusion-deformation”phenomenon.To overcome this long-standing structural weakness,a novel metal-nanoarmor strategy is proposed to construct a Cu-modified graphitic film(GF@Cu)with seamless heterointerface.This well-designed interface ensures superior structural stability for GF@Cu after hundreds of LNS cycles from 77 to 300 K.Moreover,GF@Cu maintains high thermal conductivity up to 1088 W m^(−1)K^(−1)with degradation of less than 5%even after 150 LNS cycles,superior to that of pure GF(50%degradation).Our work not only offers an opportunity to improve the robustness of graphitic films by the rational structural design but also facilitates the applications of thermally conductive carbon-based materials for future extreme thermal management in complex aerospace electronics. | Peijuan Zhang Yuanyuan Hao Hang Shi Jiahao Lu Yingjun Liu Xin Ming Ya Wang Wenzhang Fang Yuxing Xia Yance Chen Peng Li Ziqiu Wang Qingyun Su Weidong Lv Ji Zhou Ying Zhang Haiwen Lai Weiwei Gao Zhen Xu Chao Gao | 2024 | Nano-Micro Letters2024，16，3： | 0 |
| 15 | Superior Latent Heat Eutectic Salt Na_(2)CO_(3)-Li_(2)CO_(3)-LiF for Thermal Energy Storage:Preparation and Performance Investigation显示文摘In this paper,a novel ternary eutectic salt Na_(2)CO_(3)-Li_(2)CO_(3)-LiF was designed and investigated for concentrated solar power(CSP).The FactSage software was used to predict the composition and eutectic point of Na_(2)CO_(3)-Li_(2)CO_(3)-LiF.The microstructure,thermophysical properties,and thermal stability of eutectic salts were experimentally measured using various analytical methods.With a mass ratio of 57%:32%:11%,the eutectic salt exhibited excellent thermal storage properties with a fusion enthalpy of 413 J/g and a melting point of 426.8℃.The excellent thermal stability of the eutectic salt was reflected by a weight loss of only 0.8% at 600℃. | LI Weiwei MIAO Qi ZHANG Yelong DING Hongliang YANG Sa LAI Yuan FENG Daili DING Yulong JIN Yi TAN Linghua | 2024 | Journal of Thermal Science2024，33，2： | 0 |
| 16 | First principles study of the electronic structure and photovoltaic properties ofβ-CuGaO2 with MBJ+U approach显示文摘Based on the density functional theory,the energy band and electronic structure ofβ-CuGaO2 are calculated by the modified Becke-Johnson plus an on-site Coulomb U(MBJ+U)approach in this paper.The calculated results show that the band gap value ofβ-CuGaO2 obtained by the MBJ+U approach is close to the experimental value.The calculated results of electronic structure indicate that the main properties of the material are determined by the bond between Cu-3 d and O-2p energy levels near the valence band ofβ-CuGaO2,while a weak anti-bond combination is formed mainly by the O-2p energy level and Ga-4 s energy level near the bottom of the conduction band ofβ-CuGaO2.Theβ-CuGaO2 thin film is predicted to hold excellent photovoltaic performance by analysis of the spectroscopic limited maximum efficiency(SLME)method.At the same time,the calculated maximum photoelectric conversion efficiency of the ideal CuGaO2 solar cell is 32.4%.Relevant conclusions can expandβ-CuGaO2 photovoltaic applications. | Guoping Luo Yingmei Bian Ruifeng Wu Guoxia Lai Xiangfu Xu Weiwei Zhang Xingyuan Chen | 2020 | Journal of Semiconductors2020，41，10： | 0 |
| 17 | Composition analysis of Compound Shenhua Tablet,a seven-herb Chinese medicine for IgA nephropathy:evaluation of analyte-capacity of the assays显示文摘Compound Shenhua Tablet,a medicine comprising seven herbs,is employed in treating IgA nephropathy.This study aimed to meticulously analyze its chemical composition.Based on a list of candidate compounds,identified through extensive literature review pertinent to the tablet’s herbal components,the composition analysis entailed the systematic identification,characterization,and quantification of the constituents.The analyte-capacity of LC/ESI-MS-based and GC/EI-MS-based assays was evaluated.The identified and characterized constituents were quantified to determine their content levels and were ranked based on the constituents’daily doses.A total of 283 constituents,classified into 12 distinct categories,were identified and characterized in the Compound Shenhua Tablet.These constituents exhibited content levels of 1−10982μg·g^(−1),with daily doses of 0.01−395μmol·d^(−1).The predominant constituents,with daily doses of≥10μmol·d^(−1),include nine organic acids(citric acid,quinic acid,chlorogenic acid,cryptochlorogenic acid,gallic acid,neochlorogenic acid,isochlorogenic acid C,isochlorogenic acid B,and linoleic acid),five iridoids(specnuezhenide,nuezhenoside G13,nuezhenidic acid,secoxyloganin,and secologanoside),two monoterpene glycosides(paeoniflorin and albiflorin),a sesquiterpenoid(curzerenone),a triterpenoid(oleanolic acid),and a phenylethanoid(salidroside).Additionally,there were 83,126,and 55 constituents detected in the medicine with daily doses of 1–10,0.1–1,and 0.01–0.1μmol·d^(−1),respectively.The combination of the LC/ESI-MS-based and GC/EI-MS-based assays demonstrated a complementary relationship in their analyte-capacity for detecting the constituents present in the medicine.This comprehensive composition analysis establishes a solid foundation for further pharmacological research on Compound Shenhua Tablet and facilitates the quality evaluation of this complex herbal medicine. | ZHANG Haiyan WANG Qiuyue WANG Jianan ZHANG Sichao JIA Weiwei HE Ning XIA Xiaoyan WANG Ting LAI Liyu LI Jiaying DU Jing OLALEYE Olajide E CHEN Xiangmei YANG Junling LI Chuan | 2024 | Chinese Journal of Natural Medicines2024，22，2： | 0 |

| 19 | Removal of Stripes in Remote Sensing Images Based on Statistics Combined with Image Enhancement显示文摘A method to remove stripes from remote sensing images is proposed based on statistics and a new image enhancement method.The overall processing steps for improving the quality of remote sensing images are introduced to provide a general baseline.Due to the differences in satellite sensors when producing images,subtle but inherent stripes can appear at the stitching positions between the sensors.These stitchingstripes cannot be eliminated by conventional relative radiometric calibration.The inherent stitching stripes cause difficulties in downstream tasks such as the segmentation,classification and interpretation of remote sensing images.Therefore,a method to remove the stripes based on statistics and a new image enhancement approach are proposed in this paper.First,the inconsistency in grayscales around stripes is eliminated with the statistical method.Second,the pixels within stripes are weighted and averaged based on updated pixel values to enhance the uniformity of the overall image radiation quality.Finally,the details of the images are highlighted by a new image enhancement method,which makes the whole image clearer.Comprehensive experiments are performed,and the results indicate that the proposed method outperforms the baseline approach in terms of visual quality and radiation correction accuracy. | Xiaofei QU Weiwei ZHAO En LONG Meng SUN Guangling LAI | 2023 | Journal of Geodesy and Geoinformation Science2023，6，1： | 0 |
| 20 | Alkyl-thiophene-alkyl linkers to construct double-cable conjugated polymers for single-component organic solar cells显示文摘In this work,semirigid linkers of the alkyl-thiophene-alkyl structure are developed to construct double-cable polymers.Three alkyl units,propyl(C3H6),hexyl(C6H12),and dodecyl(C12H24),are applied as semirigid linkers,yielding three double-cable polymers:PBC6-T,PBC12-T,and PBC24-T,respectively.PBC12-T which uses C6H12-thiophene-C6H12 linkers is found to exhibit the best device efficiency of 5.56%,while PBC6-T and PBC24-T with shorter or longer linkers yield device efficiencies of only 2.65%and 1.09%in single-component organic solar cells(SCOSCs).Further studies reveal that PBC12-T exhibits higher crystallinity and improved charge transport,resulting in better efficiencies.Our work provides an approach to construct double-cable conjugated polymers with long alkyl linkers,and it shows the importance of the linker length for the photovoltaic performance of SCOSCs. | Wenbin Lai Safakath Karuthedath Chengyi Xiao Lei Meng Frédéric Laquai Weiwei Li Yongfang Li | 2024 | Chinese Chemical Letters2024，35，1： | 0 |
