Epstein-Barr virus infection mechanisms

引用

Chinese Journal of Cancer 2014年第11期33卷 545-548页

作者： liudmila S.Chesnokova Lindsey M.Hutt-Fletcher Department of Microbiology and Immunology Center for Molecular Tumor Virology and Feist-Weiller Cancer CenterLouisiana State University Health Sciences CenterShreveportLA 71130USA

Epstein-Barr virus(EBV) infection occurs by distinct mechanisms across different cell types. EBV infection of B cells in vitro minimally requires 5 viral glycoproteins and 2 cellular proteins. By contrast, infection of epithelial cells requires a minimum of 3 viral glycoproteins, which are capable of interacting with one or more of 3 different cellular proteins. The full complement of proteins involved in entry into all cell types capable of being infected in vivo is unknown. This review discusses the events that occur when the virus is delivered into the cytoplasm of a cell, the players known to be involved in these events, and the ways in which these players are thought to function.

In the present work, the molecular structures of two new synthesized dyes：（4,6-dimethylpyrimidin-2-ylamino）（5-p-tolylisoxazol-3-yl）methanol（PS-1） and N-（4,6-dimethylpyrimidin-2-yl）-5-phenylisoxazole-3-carboxamide（PS-2）, have been investigated using density functional theory（DFT） in dimethylformamide（DMF） for the first time. The electronic spectra of new dyes in a DMF solvent were carried out by time dependent density functional theory（TD-DFT） method. After quantum-chemical calculations two new dyes for the optoelectronic applications were synthesized. FT-IR spectra of the title compounds are recorded and discussed. NucleusIndependent Chemical Shifts（NICS） calculations have also been carried out for the title compounds. The computed absorption spectral data of the title compounds are in good agreement with the experimental data, thus allowing an assignment of the UV spectra. The HOMO and LUMO molecular orbitals, excitation energies and oscillator strengths for the dyes have also been calculated and presented.

In the present work, for the first time on the basis ofpoly （vinyl alcohol）（PVA）, 2- （4-dimethylaminostyryl）-l-ethylquinolinium iodide （quinaldine red （QR）） and trisodium （4E）-5-oxo- 1-（4-sulfonatophenyl）-4-[（4-sulfonatophenyl）hydrazono]-3 pyrazolecarboxylate （tartrazine （T））, thermostable polarizing film in a wide range of spectra （λmax=394-511 nm） with polarization efficiency （PE） = 98% in absorption maximum and stretching degree （Rs） = 3.5 was developed. The basic spectral-polarization parameters （polarization efficiency and transmittance） of oriented colored PVA-films were measured and discussed. During the work it was found that oriented PVA-films are the phenomenon of anisotropy of thermal conductivity （λ｜/λ⊥）. It is a very important parameter for the development of thermostable PVA-polarizing films. For the first time quantum-chemical calculations using density functional theory （DFT） approach for structural analysis and electronic spectrum of the QR were carried out via the B3LYP/dgdzvp and TDB3LYP/dgdzvp methods. Interpretation of absorption strips in visible region of spectrum was also reported. The excitation energies, electronic transitions and oscillator strengths for the studied structures have also been calculated （B3LYP/dgdzvp）. The NBO analysis and Mulliken atomic charges of the QR were carried out.

Russia＇s Vision of the Belt and Road Initiative：From the Rivalry of the Great Powers to Forging a New Cooperation Model in Eurasia

引用

China & World Economy 2017年第5期25卷 62-77页

作者： Ivan Timofeev Yaroslav Lissovolik liudmila Filippova Associate Professor Moscow State Institute of International Relations of the Ministry of Foreign Affairs of Russia Russia Chief Economist Eurasian Development Bank Russia Program Manager the Arctic and Asia Pacific Russian International Affairs Council (RIAC) Russia

The article aims to highlight Russian approaches to Chinese One Belt-One Roadinitiative. It examines possible opportunities and challenges for co-development of theEurasian Economic Union and the Belt project. Both projects and their co-developmentmay reduce the uncertainty in Eurasia, caused by significant structural changes ininternational relations and the world economy, the emergence of new trade regimesand the erosion of leadership in international affairs. Russian interests in this regardare determined by the need for modernization and long-term development, which couldalso help to address acute security issues. These particular factors encouraged Russiato come up with an ambitious plan of the Extensive Eurasian Partnership, although theprospects of its implementation currently are uncertain. The present article argues thatthe success of Russia-China collaboration in Eurasia will depend crucially on the futuredynamics of the Eurasian integration, as well as on the agreement to co-develop theEurasian Economic Union and the Belt Initiative with concrete and mutually beneficialprojects.

This paper devoted to finding processing methods of alkaline hydrolysate produced from rice husk pre-extraction, and discusses alkaline hydrolysate processing schemed and disengagement of some products： amorphous silica of various quality, alkaline lignin, and water and alkaline extraction polysaccharides. Silica samples were characterized： crude （air-dried）, burnt （no preliminary water treatment）, washed in distilled water, and washed in distilled water and burnt. Waste water parameters upon the extraction of solids from alkaline hydrolysate dropped a few dozens or thousand times depending on the applied processing method. Color decreased a few thousand times, turbidity was virtually eliminated, chemical oxygen demanded about 20–136 times; polyphenols content might decrease 50% or be virtually eliminated. The most prospective scheme obtained the two following solid products from rice husk alkaline hydrolysate： amorphous silica and alkaline extraction polysaccharide. Chemical oxygen demand of the remaining waste water decreased about 140 times compared to the silica-free solution.
