| 1 | Properties of Polysaccharides in Several Seaweeds from Atlantic Canada and Their Potential Anti-Influenza Viral Activities显示文摘To explore the polysaccharides from selected seaweeds of Atlantic Canada and to evaluate their potential anti-influenza virus activities, polysaccharides were isolated from several Atlantic Canadian seaweeds, including three red algae (Polysiphonia lanosa, Furcellaria lumbricalis, and Palmaria palmata), two brown algae (Ascophyllum nodosum and Fucus vesiculosus), and one green alga (Ulva lactuca) by sequential extraction with cold water, hot water, and alkali solutions. These polysaccharides were ana-lyzed for monosaccharide composition and other general chemical properties, and they were evaluated for anti-influenza virus activities. Total sugar contents in these polysaccharides ranged from 15.4% (in U. lactuca) to 91.4% (in F. lumbricalis); sulfation level was as high as 17.6% in a polysaccharide from U. lactuca, whereas it could not be detected in an alikali-extract from P. palmaria. For polysaccharides from red seaweeds, the main sugar units were sulfated galactans (agar or carrageenan) for P. lanosa, F. lumbricalis, and xylans for P. palmata. In brown seaweeds, the polysaccharides largely contained sulfated fucans, whereas the polysaccharides in green seaweed were mainly composed of heteroglycuronans. Screening for antiviral activity against influenza A/PR/8/34 (H1N1) virus revealed that brown algal polysaccharides were particularly effective. Seaweeds from Atlantic Canada are a good source of marine polysaccharides with potential antiviral properties. | JIAO Guangling YU Guangli WANG Wei ZHAO Xiaoliang ZHANG Junzeng Stephen H.

| 2 | A history of high-power laser research and development in the United Kingdom显示文摘The first demonstration of laser action in ruby was made in 1960 by T.H.Maiman of Hughes Research Laboratories,USA.Many laboratories worldwide began the search for lasers using different materials,operating at different wavelengths.In the UK,academia,industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications.This historical review looks at the contribution the UK has made to the advancement of the technology,the development of systems and components and their exploitation over the last 60 years. | Colin N.Danson Malcolm White John R.M.Barr Thomas Bett Peter Blyth David Bowley Ceri Brenner Robert J.Collins Neal Croxford A.E.Bucker Dangor Laurence Devereux Peter E.Dyer Anthony Dymoke-Bradshaw Christopher B.Edwards Paul Ewart Allister I.Ferguson John M.Girkin Denis R.Hall David C.Hanna Wayne Harris David I.Hillier Christopher J.Hooker Simon M.Hooker Nicholas Hopps Janet Hull David Hunt Dino A.Jaroszynski Mark Kempenaars Helmut Kessler Sir Peter L.Knight Steve Knight Adrian Knowles Ciaran L.S.Lewis Ken S.Lipton Abby Littlechild John Littlechild Peter Maggs Graeme P.A.Malcolm OBE Stuart P.D.Mangles William Martin Paul McKenna Richard O.Moore Clive Morrison Zulfikar Najmudin David Neely Geoff H.C.New Michael J.Norman Ted Paine Anthony W.Parker Rory R.Penman Geoff J.Pert Chris Pietraszewski Andrew Randewich Nadeem H.Rizvi Nigel Seddon MBE Zheng-Ming Sheng David Slater Roland A.Smith Christopher Spindloe Roy Taylor Gary Thomas John W.G.Tisch Justin S.Wark Colin Webb S.Mark Wiggins Dave Willford Trevor Winstone | 2021 | High Power Laser Science and Engineering2021，9，2： | 5 |
