1A de novo Genome of a Chinese Radish Cultivar显示文摘Here, we report a high-quality draft genome of a Chinese radish(Raphanus sativus) cultivar. This draft contains 387.73 Mb of assembled scaffolds, 83.93% of the scaffolds were anchored onto nine pseudochromosomes and 95.09% of 43 240 protein-coding genes were functionally annotated. 184.75 Mb(47.65%) of repeat sequences was identified in the assembled genome. By comparative analyses of the radish genome against 10 other plant genomes, 2 275 genes in 780 gene families were found unique to R. sativus. This genome is a good reference for genomic study and of great value for genetic improvement of radish.ZHANG Xiaohui YUE Zhen MEI Shiyong QIU Yang YANG Xinhua CHEN Xiaohua CHENG Feng WU Zhangyan SUN Yuyan JING Yi LIU Bo SHEN Di WANG Haiping CUI Na DUAN Yundan WU Jian WANG Jinglei GAN Caixia WANG Jun WANG Xiaowu LI Xixiang 2015Horticultural Plant Journal2015,1,3:10
2Magnetic performance and corrosion resistance of electroless plating CoWP film显示文摘The CoWP film with good magnetic performance and corrosion resistance was electrolessly plated from alkaline solution. The technical parameters of the electroless plating system were optimized. When the pH value of electroless plating solution was 11.0 and the reducing agent (NaH2PO2) content was 0.4 mol L 1, the target chemical reactions proceeded in the electroless plating solution smoothly with negligible interference and side effects. CoWP film prepared under optimal deposition condition contained more hexagonal close-packed (hcp) cobalt (ε-Co) of [110] and crystallographic orientation of Co [002]. VSM analysis reveals that the saturation magnetization of the CoWP film is 100~220 Am2 kg 1 and coercivity is (2.87~4.38)×104 A·cm 1. The corrosion behavior of CoWP film in 3.5% NaCl aqueous solution was studied by electrochemical experiments. The results prove that the corrosion resistance of the CoWP film deposited under the optimal depo-sition condition exhibites relatively lower corrosion current of (3.054~3.162)×10 6 A·cm 2. The surface morphology analysis indicates that the film is smooth and composed of regular-shaped crystallites.Jiang, Li Pan, Shanshan Lu, Jianbiao Ke, Xin He, Wenhao Yu, Yundan Wei, Guoying Ge, Hongliang 2012Rare Metals2012,31,3:6
3Hydrothermal exfoliated molybdenum disulfide nanosheets as anode material for lithium ion batteries显示文摘Ultrathin MoS2nanosheets were prepared in high yield using a facile and effective hydrothermal intercalation and exfoliation route. The products were characterized in detail using X-ray diffraction, scanning electron microscopy, transmission electron microscopy and Raman spectroscopy. The results show that the high yield of MoS2nanosheets with good quality was successfully achieved and the dimensions of the immense nanosheets reached 1 μm–2 μm. As anode material for Li-ion batteries, the as-prepared MoS2nanosheets electrodes exhibited a good initial capacity of 1190 mAh g-1and excellent cyclic stability at constant current density of 50 mA g-1. After 50 cycles, it still delivered reversibly sustained high capacities of 750 mAh g-1.Yundan Liu Long Ren Xiang Qi Liwen Yang Jun Li Yao Wang Jianxin Zhong 2014Journal of Energy Chemistry2014,23,2:4
4Topological Shape Changes Weaken the Innate Defensive Response to Visual Threat in Mice显示文摘Understanding the primitives of visual perception is a fundamental question in the study of vision.T o address this question,a theory of topology-based functional hierarchy in visual perception has been proposed[1,2].This theory suggests that the extraction of topological properties(TPs)serves as the starting point of object perception.The T P of a figure is the holistic identity which remains constant across various smooth shape-changing transformations of an image[2].Yan Huang Lei Li Kun Dong Hongsi Tang Qingning Yang Xianglian Jia Yundan Liao Wenbo Wang Zhen Ren Lin Chen Liping Wang 2020Neuroscience Bulletin2020,36,4:2
5Downstream signaling of reactive oxygen species,protein kinase C epsilon translocation and delayed neuroprotection in sevoflurane preconditioned rats following cerebral ischemia/reperfusion显示文摘BACKGROUND:Brief exposure to the anesthetic sevoflurane results in delayed neuroprotection. However,few studies have addressed delayed neuroprotection after preconditioning with a single administration of sevoflurane. OBJECTIVE:To explore the relationship between a single preconditioning administration of sevoflurane and reactive oxygen species production and protein kinase C-epsilon(PKC-ε) translocation. DESIGN,TIME,AND SETTING:The randomized,controlled,animal experiment was conducted at the Central Laboratory,Xiangya Hospital,Central South University,China from November 2007 to April 2008. MATERIALS:A total of 120 healthy,male,Sprague Dawley rats were equally and randomly assigned into five groups:sham operation,ischemia/reperfusion,sevoflurane,2-mercaptopropionylglycine (2-MPG,a selective reactive oxygen species scavenger) + sevoflurane(MPG + sevoflurane),and MPG.Sevoflurane(Baxter,USA) and MPG(Sigma,USA) were used in this study. METHODS:Intervention consisted of three procedures.(1) MPG injection:a selective reactive oxygen species scavenger,MPG(20 mg/kg),was infused into the rat caudal vein in the MPG and MPG + sevoflurane groups.(2) Sevoflurane preconditioning:30 minutes following MPG injection, rats in the sevoflurane and MPG + sevoflurane groups breathed a mixed gas of 2.4%sevoflurane and 97.6%oxygen for 60 minutes.Rats in the sham operation,ischemia/reperfusion,and MPG groups breathed 100%pure oxygen for 60 minutes.(3) Ischemia/reperfusion:24 hours after sevoflurane or pure oxygen preconditioning,middle cerebral artery occlusion models were established in the ischemia/reperfusion,sevoflurane,MPG + sevoflurane,and MPG groups. Following 2 hours ischemia/6 hours and 24 hours reperfusion,the carotid artery was separated,but the middle cerebral artery was not occluded,in the sham operation group. MAIN OUTCOME MEASURES:In the ischemic hemisphere,PKC-εtranslocation in the rat parietal cortex was measured by Western blot analysis.Infarct volume was calculated using the TTC assay.Neurological deficits were evaluated in rats using a scoring system of 8 points. RESULTS:After 6 hours reperfusion,the ratio of PKC-εin membrane/(cytosol + membrane) was significantly less in the sham operation group than in the ischemia/reperfusion,sevoflurane,MPG + sevoflurane),and MPG groups(P<0.05).The ratio of PKC-εin membrane/(cytosol + membrane) was significantly greater in the sevoflurane group than in the sham operation,ischemia/reperfusion, MPG + sevoflurane,and MPG groups(P<0.05).No significant differences were observed in the ischemia/reperfusion,MPG + sevoflurane,and MPG groups(P>0.05).Following 24 hours reperfusion, the ratio of PKC-εin membrane/(cytosol + membrane) was significantly less in the sham operation group than in the ischemia/reperfusion,sevoflurane,MPG + sevoflurane,and MPG groups(P<0.05). No significant differences were detected in the ischemia/reperfusion,sevoflurane,MPG + sevoflurane, and MPG groups(P>0.05).Compared with the ischemia/reperfusion,MPG + sevoflurane,and MPG groups,infarct volume was significantly smaller,and neurological deficits were significantly improved, in the sevoflurane group(P<0.05).No significant differences in infarct volume and neurological deficits were observed among the ischemia/reperfusion,MPG + sevoflurane,and MPG groups(P>0.05).Infarcts or neurological deficits were not detected in the sham operation group. CONCLUSION:A single preconditioning administration of sevoflurane reduced infarct volumes and improved neurological deficits in ischemic rats.Delayed neuroprotection may be mediated by reactive oxygen species and correlated to PKC-εactivation.Zhi Ye Qulian Guo E Wang Yundan Pan Qing Li Honghao Zhou 2009Neural Regeneration Research2009,4,3:1
6Substation clustering based on improved KFCM algorithm with adaptive optimal clustering number selection显示文摘The premise and basis of load modeling are substation load composition inquiries and cluster analyses.However,the traditional kernel fuzzy C-means(KFCM)algorithm is limited by artificial clustering number selection and its convergence to local optimal solutions.To overcome these limitations,an improved KFCM algorithm with adaptive optimal clustering number selection is proposed in this paper.This algorithm optimizes the KFCM algorithm by combining the powerful global search ability of genetic algorithm and the robust local search ability of simulated annealing algorithm.The improved KFCM algorithm adaptively determines the ideal number of clusters using the clustering evaluation index ratio.Compared with the traditional KFCM algorithm,the enhanced KFCM algorithm has robust clustering and comprehensive abilities,enabling the efficient convergence to the global optimal solution.Yanhui Xu Yihao Gao Yundan Cheng Yuhang Sun Xuesong Li Xianxian Pan Hao Yu 2023Global Energy Interconnection2023,6,4:0
7Effect of magnetic fields on pulse plating of cobalt films显示文摘Magnetic fields parallel to the electrodes were introduced during a pulse plating process to obtain cobalt thin films from alkaline baths. Ef-fects of different magnetic intensities on the composition, microstructure, and magnetic properties of cobalt thin films were investigated. It was found that the deposition speed increased gradually with the increase of magnetic intensity. Almost all of the deposited films were crys-talline and showed Co(002), Co(100) peaks. With the rise on the magnetic intensity, the intensity of Co (002) peak raised gradually. Mag-netic fields would induce cobalt growing along (002) orientation. The films were densely covered with typical nodular structure. Films of smaller grain size and smooth surface could be formed under high magnetic intensity (1 T) as a result of magnetic force and MHD effects. Moreover, higher magnetic intensity induced larger saturation magnetization and lower coercivity. With the rise on magnetic intensity, cobalt contents in the films increased gradually, which led to the rise of saturation magnetization.Yu, Yundan Li, Wei Lou, Junwei Ge, Hongliang Sun, Lixia Jiang, Li Wei, Guoying 2012Rare Metals2012,31,2:0
8Carbon matrix/SiNWs heterogeneous block as improved reversible anodes material for lithium ion batteries显示文摘A novel carbon matrix/silicon nanowires(SiNWs) heterogeneous block was successfully produced by dispersing SiNWs into templated carbon matrix via a modified evaporation induced self-assembly method. The heterogeneous block was determined by X-ray diffraction, Raman spectra and scanning electron microscopy. As an anode material for lithium batteries, the block was investigated by cyclic voltammograms(CV), charge/discharge tests, galvanostatic cycling performance and A. C. impedance spectroscopy. We show that the SiNWs disperse into the framework, and are nicely wrapped by the carbon matrix. The heterogeneous block exhibits superior electrochemical reversibility with a high specific capacity of 529.3 mAh/g in comparison with bare SiNWs anode with merely about 52.6 mAh/g capacity retention. The block presents excellent cycle stability and capacity retention which can be attributed to the improvement of conductivity by the existence of carbon matrix and the enhancement of ability to relieve the large volume expansion of SiNWs during the lithium insertion/extraction cycle. The results indicate that the as-prepared carbon matrix/SiNWs heterogeneous block can be an attractive and potential anode material for lithium-ion battery applications.Yao Wang Long Ren Yundan Liu Xuejun Liu Kai Huang Xiaolin Wei Jun Li Xiang Qi Jianxin Zhong 2014Journal of Energy Chemistry2014,23,1:0

10Genomic diversity and ecological distribution of marine Pseudoalteromonas phages显示文摘Pseudoalteromonas,with a ubiquitous distribution,is one of the most abundant marine bacterial genera.It is especially abundant in the deep sea and polar seas,where it has been found to have a broad metabolic capacity and unique co-existence strategies with other organisms.However,only a few Pseudoalteromonas phages have so far been isolated and investigated and their genomic diversity and distribution patterns are still unclear.Here,the genomes,taxonomic features and distribution patterns of Pseudoalteromonas phages are systematically analyzed,based on the microbial and viral genomes and metagenome datasets.A total of 143 complete or nearly complete Pseudoalteromonas-associated phage genomes(PSAPGs)were identifed,including 34 Pseudoalteromonas phage isolates,24 proviruses,and 85 Pseudoalteromonas-associated uncultured viral genomes(UViGs);these were assigned to 47 viral clusters at the genus level.Many integrated proviruses(n=24)and flamentous phages were detected(n=32),suggesting the prevalence of viral lysogenic life cycle in Pseudoalteromonas.PSAPGs encoded 66 types of 249 potential auxiliary metabolic genes(AMGs)relating to peptidases and nucleotide metabolism.They may also participate in marine biogeochemical cycles through the manipulation of the metabolism of their hosts,especially in the phosphorus and sulfur cycles.Siphoviral and flamentous PSAPGs were the predominant viral lineages found in polar areas,while some myoviral and siphoviral PSAPGs encoding transposase were more abundant in the deep sea.This study has expanded our understanding of the taxonomy,phylogenetic and ecological scope of marine Pseudoalteromonas phages and deepens our knowledge of viral impacts on Pseudoalteromonas.It will provide a baseline for the study of interactions between phages and Pseudoalteromonas in the ocean.Kaiyang Zheng Yue Dong Yantao Liang Yundan Liu Xinran Zhang Wenjing Zhang Ziyue Wang Hongbing Shao Yeong Yik Sung Wen Jye Mok Li Lian Wong Andrew McMinn Min Wang 2023Marine Life Science & Technology2023,5,2:0
