1牛腔前卵泡在体外无血清培养中发育为有腔卵泡显示文摘用无血清培养系统研究了牛腔前卵泡的体外培养。直径为 10 0~ 2 0 0μm的牛腔前卵泡在添加 L -谷氨酰胺、BSA、睾酮、转铁蛋白和硒的 Mc Coy′s5 a培养液中培养 ,卵泡保持正常的形态结构并持续生长 ,培养 10 d左右形成卵泡腔 ,成腔率约 5 0 %。培养液中添加胰岛素对卵泡直径的增长和卵泡腔的形成有明显的促进作用 ,但添加 FSH对腔前卵泡的生长未表现促进作用。周虚 Robert Webb 2002中国兽医学报2002,22,5:18

3A 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 2021High Power Laser Science and Engineering2021,9,2:5
4Monitoring Greenhouses Gases over China Using Space-Based Observations Monitoring Greenhouses Gases over China Using Space-Based Observations显示文摘The atmospheric carbon dioxide(CO 2)concentration has increased to more than 405 parts per million(ppm.1 ppm=10-6 m/s 2)in 2017 due to human activities such as deforestation,land-use change and burning of fossil fuels.Although there is broad scientific consensus on the damaging consequences of the change in climate associated with increasing concentrations of greenhouse gases,fossil CO 2 emissions have continued to increase in recent years mainly from rapidly developing economies and China is now the largest emitter of CO 2 generating about 30%of all emissions globally.To allow more reliable forecast of the future state of the carbon cycle and to support the efforts for mitigation greenhouse gas emissions,a better understanding of the global and regional carbon budget is needed.Space-based measurements of CO 2 can provide the necessary observations with dense coverage and sampling to provide improved constrains on of carbon fluxes and emissions.The Chinese Global Carbon Dioxide Monitoring Scientific Experimental Satellite(TanSat)was established by the National High Technology Research and Development Program of China with the main objective of monitoring atmospheric CO 2 and CO 2 fluxes at the regional and global scale.TanSat has been successfully launched in December 2016 and as part of the Dragon programme of ESA and the Ministry of Science and Technology(MOST),a team of researchers from Europe(UK and Finland)and China has evaluated early TanSat data and contrast it against data from the GOSAT mission and models.In this manuscript,we report on retrieval intercomparisons of TanSat data using two different retrieval algorithms,on validation efforts for the Eastern Asia region using GOSAT CO 2 data and first assessments of TanSat and GOSAT CO 2 data against model calculations using the GEOS-Chem model.Hartmut BOESCH Yi LIU Paul I PALMER Johanna TAMMINEN Jasdeep S ANAND Zhaonan CAI Ke CHE Huilin CHEN Xi CHEN Liang FENG Janne HAKKARAINEN Pauli HEIKKINEN Nikoleta KALAITZI Rigel KIVI Robert PARKER Peter SOMKUTI Jing WANG Alex WEBB Dongxu YANG Lu YAO You YI 2020Journal of Geodesy and Geoinformation Science2020,3,4:2

11地氟烷与七氟烷在门诊手术全身麻醉维持中的对比研究:对苏醒早晚期及围手术期咳嗽的影响显示文摘背景目前地氧垸已经用于门诊全身麻醉手术的维持阶段,其相对于七氖烷在围手术期的优略性尚存争议。尽管各研究一致指出,地氟烷比七氟烷苏醒更快,但这种差异对苏醒晚期的影响却未有明确报道。并且,地氟烷与七氟烷相比,对咳嗽发生率的影响也存在争议。方法本研究中纳入了130例在全身麻醉下行浅表门诊手术的患者,随机分为2组。所有患者都静脉注射丙泊酚2mg/kg诱导,置入喉罩,采用1%-3%的七氟烷或3%-8%的地氟炕维持麻醉,吸入混合空气或氧气。调节吸入麻醉药的浓度,维持血流动力学稳定,并维持脑电双频谱指数(BIS)于50—60。并用局部浸润和静脉注射酮洛酸30mg镇痛。在手术结束时给予预防性止吐药物,包括昂丹司琼4mg、地塞米松4mg及甲氧氨普胺10mg。评估标准包括睁眼恢复时间,对指令做出反应的时间,定向力恢复的时间,14分快通道评分,首次进食时间,能坐立,可站立,独立行走及出院时间。手术后早期及离院后24小时内,记录患者对于麻醉的满意度,手术后第1天恢复正常活动的能力,不良反应的发生(如咳嗽、意向性运动、氧饱和度〈90%、咽痛及手术后恶心、呕吐),手术后镇痛药及止吐药的使用情况。结果2组患者的流行病学资料相近。尽管围手术期地氯烷组咳嗽的总体发生率高于七氟烷组(分别为60%和32%,P〈0.05),然而在真正应用吸入麻醉药期间(即麻醉维持中),咳嗽发生率的组间差异无显著性。地氧烷组患者苏醒较快,但两组所有患者在离开手术室之前都达到了快通道恢复标准(快通道评分≥12)。此外,离院时间(七氟炕组90±31分钟,地氟炕组98±5分钟)及手术后第1天能恢复正常活动的患者比率(七氟烷48%,地氟炕60%),在两组间的差异无显著性。结论用地氧烷进行维持全身麻醉具有苏醒迅速、咳嗽发生率高的特点。尽管与七氟烷相比,地氟炕在麻醉早期恢复较快,但两组晚期恢复的差异无显著性。两种吸入麻醉药都适用于门诊手术的麻醉。Paul F.
