1Object Recognition Based on Improved Context Model显示文摘An object recognition method is proposed in this paper by introducing the spatial location relationship of objects into the context model. The spatial-position information of the objects is first utilized to model the context model. The model parameters and dependency structure of objects can be learned by integrating the context information into the same probabilistic framework. The image recognition is accomplished by using the advantages of efficient inference of the tree structure model. The proposed method can greatly improve the object recognition rate and better keep the consistency of scenes. The effectiveness of the proposed algorithm is verified by testing and comparing with other existing algorithms in the actual dataset.WEN Chenglin ZHOU Guangfu GAO Jingli LI Hongwei XU Xiaobin 2018Chinese Journal of Electronics2018,27,3:1

3In vitro anther culture and Agrobacterium-mediated transformation of the AP1 gene from Salix integra Linn. in haploid poplar(Populus simonii × P. nigra)显示文摘A reliable,efficient anther culture system,the dominant technique for generating haploid plants in breeding programs,that can be used for generating transgenic poplar plants has been needed.In the present study,therefore,an anther culture system was developed using isolated mid-and late-uninucleate anthers of poplar(Populus simonii x P.nigra).From a combination of SSR and ploidy analyses,six double haploid and two haploid lines were characterized from 86 plants grown from 16 regenerated anther cultured lines.After 48 months of development,two plant lines from the regenerated plants maintained their haploid level in vitro for over 2 years.A number of haploid plants from the different lines weretransferred to soil.The leaves of these transplants were then used as explants for transformation with the APETALA1(AP1) gene using Agrobacterium tumefaciens.Overexpression of AP1 in haploid poplar induced early flowering with obvious petals when ectopically expressed.To our knowledge,this is the first report on changes in flowering time in AP1-trangenic poplar,which is important for elucidating the regulatory mechanism of tree flower development.Jingli Yang Kun Li Chunyan Li Junxiu Li Bo Zhao Wei Zheng Yuchi Gao Chenghao Li 2018Journal of Forestry Research2018,29,2:1

5Interfacial charge effects of supported-metal-cluster heterostructures on azo hydrogenation catalyzation显示文摘The impact of interfacial charge on catalytic performance of supported-metal-cluster(SMC)heterostructures remains unclear,hindering efforts to develop high-performance SMC catalysts.Herein we systematically investigated interfacial charge effects of SMCs using a model system of graphene-supported gold-nanoclusters(AuNCs/rGO)for azo hydrogenation.Three types of SMCs with different interfacial charges were synthesized by anchoring electropositive 2-aminoethanethiol(CSH),amphoteric cysteine(Cys),and electronegative 3-mercaptopropionic-acid(MPA)onto AuNCs/rGO,respectively.All three SMCs exhibited high and selective catalytic activity to azo-hydrogenation in four representative azo dyes.The catalytic activity of Cys@AuNCs/rGO was lower than that of CSH@AuNCs/rGO but higher than that of MPA@AuNCs/rGO.However,the cyclic stability of Cys@AuNCs/rGO was inferior to that of both CSH@AuNCs/rGO and MPA@AuNCs/rGO.Further mechanistic studies revealed that amino ligands modified CSH@AuNCs and Cys@AuNCs agglomerated into large-size gold nanoparticles on rGO surface during catalytic reaction under NaBH_(4) action,leading to reduced efficiency and cyclic stability.Conversely,non-amino ligand modified MPA@AuNCs only partially detached from rGO surface without agglomeration,resulting in better cyclic stability.Protection of amino groups in ligands such as modifying-NH_(3)^(+)group in Cys into imine to form N-isobutyryl-L-cysteine(NIBC)substantially improved the cyclic stability while maintaining the high activity in the NIBC@AuNCs/rGO catalyst system.Our work provides an approach for developing a highly-active and stable SMC heterostructure catalyst via manipulating interfacial charges in SMC.Zhenhua Gu Jingli Zhang Zijun Zhang Qingxue Mu Liangchong Yu Taolei Sun Lei Shen Guanbin Gao 2024Nano Research2024,17,5:0
6Enhancing maize's nitrogen-fixing potential through ZmSBT3, a gene suppressing mucilage secretion∞显示文摘Maize(Zea mays)requires substantial amounts of nitrogen,posing a challenge for its cultivation.Recent work discovered that some ancient Mexican maize landraces harbored diazotrophic bacteria in mucilage secreted by their aerial roots.To see if this trait is retained in modern maize,we conducted a field study of aerial root mucilage(ARM)in 258 inbred lines.We observed that ARM secretion is common in modern maize,but the amount significantly varies,and only a few lines have retained the nitrogen‐fixing traits found in ancient landraces.The mucilage of the high‐ARM inbred line HN5‐724 had high nitrogen‐fixing enzyme activity and abundant diazotrophic bacteria.Our genome‐wide association study identified 17 candidate genes associated with ARM across three environments.Knockouts of one candidate gene,the subtilase family gene ZmSBT3,confirmed that it negatively regulates ARM secretion.Notably,the ZmSBT3 knockout lines had increased biomass and total nitrogen accumulation under nitrogen‐free culture conditions.High ARM was associated with three ZmSBT3 haplotypes that were gradually lost during maize domestication,being retained in only a few modern inbred lines such as HN5‐724.In summary,our results identify ZmSBT3 as a potential tool for enhancing ARM,and thus nitrogen fixation,in maize.Jingyang Gao Peijiang Feng Jingli Zhang Chaopei Dong Zhao Wang Mingxiang Chen Zhongliang Yu Bowen Zhao Xin Hou Huijuan Wang Zhaokun Wu Razia Sultana Jemim Haidong Yu Doudou Sun Pei Jing Jiafa Chen Weibin Song Xuecai Zhang Zijian Zhou Jianyu Wu 2023Journal of Integrative Plant Biology2023,65,12:0
7The expression and function of long noncoding RNAs in hepatocellular carcinoma显示文摘With the deepening of the genome project study,attention on noncoding RNAs is increasing.Long noncoding RNAs(lncRNAs)have become a new research hotspot.A growing number of studies have revealed that lncRNAs are involved in tumorigenesis and tumor suppressor pathways.Aberrant expressions of lncRNAs have been found in a variety of human tumors including hepatocellular carcinoma(HCC).In this review,we provide a brief introduction to lncRNA and highlight recent research on the functions and clinical significance of lncRNAs in HCC.Jingli Du Yue Su Jianzhi Gao Yanhong Tai 2023Cancer Innovation2023,2,6:0
8Transition of the generation mechanism of high-order harmonics in an extended neon system显示文摘Using a time-dependent density functional theory method,we perform a systematic numerical study of the transition of high-order harmonic generation in neon(Ne)systems from an isolated Ne atom to an extended Ne system of solid density.We show that ionized electrons wander in such extended systems until they meet a nearby ion and collide with it.The maximum energy edge for the main feature of the high-order harmonic spectrum in this“wandering electron”picture is determined as Eedge=Ip+8Up,where Ip is the ionization energy of Ne and Up is the ponderomotive energy delivered by the driving laser.The factor of 8 comes from the maximum kinetic energy of an ionized electron in the driving laser field.Beyond the atomic limit of high-order harmonic spectra,a multiplatform feature is observed,corresponding to re-collisions of ionized electrons with their nearby ions.It is also shown that a Ne simple cubic lattice of appropriate size provides a selection condition for the direction of polarization of high-order harmonics beyond the atomic limit,which may be further used to manipulate the emitted radiation.Jingli Gao Difa Ye Jie Liu Wei Kang 2022Matter and Radiation at Extremes2022,7,4:0
9Aromatase and steroid sulfatase mRNA expression in fine needle aspirates from benign and malignant breast disorders显示文摘The fine needle aspiration (FNA) test is a convenient and tolerable technique with minimal invasion that is accepted by most women.Local estrogen synthesis depends mainly on the aromatase and steroid sulfatase pathways that are believed to play important roles in breast carcinogenesis.However,little is known about the level of aromatase and steroid sulfatase mRNA expression in FNA samples which contain only small amounts of tissue.The nested Q-PCR assay has been proven to be a highly sensitive and specific method to assess the aromatase expression of breast tissue.In this study,aromatase and steroid sulfatase mRNA expression in 74 patients with benign or malignant disorders was evaluated and compared using nested Q-PCR and non-nested Q-PCR assays.The expression levels were analyzed and correlated with clinical parameters.No difference in the aromatase expression levels between nested and non-nested Q-PCR was noticed.Age and aromatase mRNA expression level were two independent risk factors for breast cancer (P=0.04 and P=0.00,respectively),while menopausal status and steroid sulfatase mRNA expression levels were not associated with breast cancer.This study showed that both nested and non-nested Q-PCR assays were effective methods for research using FNA breast samples.GAO Lei QI Ying LIU JingLi YU XiaoMeng XIA Wei LIU GuiJian 2012Chinese Science Bulletin2012,57,20:0
10IL-33 Downregulates Hepatic Carboxylesterase 1 in Acute Liver Injury via Macrophage-derived Exosomal miR-27b-3p显示文摘Background and Aims:We previously reported that carboxylesterase 1(CES1)expression was suppressed following liver injury.The study aimed to explore the role of interleukin(IL)-33 in liver injury and examine the mechanism by which IL-33 regulates CES1.Methods:IL-33 and CES1 levels were determined in the livers of patients and lipopolysaccharide(LPS)-,acetaminophen(APAP)-treated mice.We constructed IL-33 and ST2 knockout(KO)mice.ST2-enriched immune cells in livers were screened to identify the responsible cells.Macrophage-derived exosome(MDE)activity was tested by adding exosome inhibitors.Micro-RNAs(miRs)were extracted from control and IL-33-stimulated MDEs(IL-33-MDEs)and subjected miR sequencing(miR-Seq).Candidate miR was tested in vitro and in vivo and its binding of a target gene was assessed by luciferase reporter assays.Lentivirus-vector cellular transfection and transcript silencing were used to examine pathways mediating IL-33 suppression of miR-27b-3p.Results:Patient liver IL-33 and CES1 expression levels were inversely correlated.CES1 downregulation in liver injury was rescued in both IL-33–deficient and ST2 KO mice.Macrophages were shown to be responsible for IL-33 effects.IL-33-MDEs reduced CES1 levels in hepatocytes.Exosomal miR-Seq and qRT-PCR demonstrated increased miR-27b-3p levels in IL-33-MDEs;miR-27b-3p was implicated in Nrf2 targeting.IL-33 inhibition of miR-27b-3p was found to be GATA3-dependent.Conclusions:IL-33–ST2–GATA3 pathway signaling increases miR-27b-3p content in MDEs,which upon being internalized by hepatocytes reduce CES1 expression by inhibiting Nrf2.The elucidation of this mechanism in this study contributes to a better understanding of CES1 dysregulation in liver injury.Ping Gao Min Li Jingli Lu Daochun Xiang Ximin Wang Yanjiao Xu Yue Zu Xinlei Guan Guodong Li Chengliang Zhang 2023Journal of Clinical and Translational Hepatology2023,11,5:0
