| 3 | Directly patterned substrate-free plasmonic “nanograter” structures with unusual Fano resonances显示文摘The application of three-dimensional(3D)plasmonic nanostructures as metamaterials(MMs),nano-antennas,and other devices faces challenges in producing metallic nanostructures with easily definable orientations,sophisticated shapes,and smooth surfaces that are operational in the optical regime and beyond.Here,we demonstrate that complex 3D nanostructures can be readily achieved with focused-ion-beam irradiation-induced folding and examine the optical characteristics of plasmonic“nanograter”structures that are composed of free-standing Au films.These 3D nanostructures exhibit interesting 3D hybridization in current flows and exhibit unusual and well-scalable Fano resonances at wavelengths ranging from 1.6 to 6.4 mm.Upon the introduction of liquids of various refractive indices to the structures,a strong dependence of the Fano resonance is observed,with spectral sensitivities of 1400 nm and 2040 nm per refractive index unit under figures of merit of 35.0 and 12.5,respectively,for low-order and high-order resonance in the near-infrared region.This work indicates the exciting,increasing relevance of similarly constructed 3D free-standing nanostructures in the research and development of photonics and MMs. | Ajuan Cui Zhe Liu Jiafang Li Tiehan H Shen Xiaoxiang Xia Zhiyuan Li Zhijie Gong Hongqiang Li Benli Wang Junjie Li Haifang Yang Wuxia Li Changzhi Gu | 2015 | Light(Science & Applications)2015,4,1: | 8 |

| 5 | Screening Helicobacter pylori genes induced during infection of mouse stomachs显示文摘AIM:To investigate the effect of in vivo environment on gene expression in Helicobacter pylori(H.pylori) as it relates to its survival in the host.METHODS:In vivo expression technology(IVET) systems are used to identify microbial virulence genes.We modified the IVET-transcriptional fusion vector,pIVET8,which uses antibiotic resistance as the basis for selection of candidate genes in host tissues to develop two unique IVET-promoter-screening vectors,pIVET11 and pIVET12.Our novel IVET systems were developed by the fusion of random Sau3A DNA fragments of H.pylori and a tandem-reporter system of chloramphenicol acetyltransferase and beta-galactosidase.Additionally,each vector contains a kanamycin resistance gene.We used a mouse macrophage cell line,RAW 264.7 and mice,as selective media to identify specific genes that H.pylori expresses in vivo.Gene expression studies were conducted by infecting RAW 264.7 cells with H.pylori.This was followed by real time polymerase chain reaction(PCR) analysis to determine the relative expression levels of in vivo induced genes.RESULTS:In this study,we have identified 31 in vivo induced(ivi) genes in the initial screens.These 31 genes belong to several functional gene families,including several well-known virulence factors that are expressed by the bacterium in infected mouse stomachs.Virulence factors,vacA and cagA,were found in this screen and are known to play important roles in H.pylori infection,colonization and pathogenesis.Their detection validates the efficacy of these screening systems.Some of the identified ivi genes have already been implicated to play an important role in the pathogenesis of H.pylori and other bacterial pathogens such as Escherichia coli and Vibrio cholerae.Transcription profiles of allivi genes were confirmed by real time PCR analysis of H.pylori RNA isolated from H.pylori infected RAW 264.7 macrophages.We compared the expression profile of H.pylori and RAW 264.7 coculture with that of H.pylori only.Some genes such as cag A,vac A,lpx C,mur I,tlp C,trx B,sod B,tnp B,pgi,rbf A and inf B showed a 2-20 fold upregulation.Statistically significant upregulation was obtained for all the above mentioned genes(P < 0.05).tlp C,cag A,vac A,sod B,rbf A,inf B,tnp B,lpx C and mur I were also significantly upregulated(P < 0.01).These data suggest a strong correlation between results obtained in vitro in the macrophage cell line and in the intact animal.CONCLUSION:The positive identification of these genes demonstrates that our IVET systems are powerful tools for studying H.pylori gene expression in the host environment. | Aparna Singh Nathaniel Hodgson Ming Yan Jungsoo Joo Lei Gu Hong Sang Emmalena Gregory-Bryson William G Wood Yisheng Ni Kimberly Smith Sharon H Jackson William G Coleman | 2012 | World Journal of Gastroenterology2012,18,32: | 5 |
