1缺血性卒中患者的早期处理指南——美国卒中学会卒中委员会科学声明显示文摘1994年,美国心脏学会(AHA)卒中委员会委托一个专门研究小组撰写了急性缺血性卒中患者的处理指南[1].1996年,在静脉rtPA治疗急性缺血性卒中得到食品与药物管理局(FDA)批准后,这项指南又补充了一系列的推荐[2].曲东锋 陈兴洲 李宏建 倪长江 Harold P.Adams Jr Robert J.Adams Thomas Brott Gregory J.del Zoppo Anthony Furlan Larry B.Goldstein Robert L.Grubb Randall Higashida Chelsea Kidwell Thomas G.Kwiatkowski John R.Marler George J.Hadermenos 2003国外医学(脑血管疾病分册)2003,11,5:57
2Nutrient changes in potting mix and Eucalyptus nitens leaf tissue under macadamia biochar amendments显示文摘The effect of macadamia nut shell biochar on nitrogen,potassium,phosphorus,magnesium,calcium and sodium concentrations in potting mix used to grow Eucalyptus nitens seedlings was investigated in a glasshouse experiment.The treatments combined two fertiliser rates(50 and 100% rate of the commercial mix commonly used in forestry nurseries) with eight biochar rates(0,2,5,10,20,50,80 and 100 t ha^(-1)) arranged in a randomised complete block with three replicates of four sample plants.Nutrients were quantified in the potting mix and seedling leaves at four destructive harvests 135,177,219 and269 days after planting.Biochar significantly increased nitrate-N,Colwell P,Colwell K and exchangeable Na andreduced ammonium-N,Mg and Ca concentrations in the potting mix.Seedling leaf concentrations of P,K and Na were increased by biochar application,while N remained dependent on fertiliser rate only.Mg and Ca leaf concentrations decreased in response to increasing biochar rates.Elevated nitrate-N and decreased ammonium-N concentrations suggest that biochar might have increased nitrification in the potting mix.We presumed that biochar mediated processes that reduced uptake of P and K when high doses of biochar were combined with full fertilisation.Changes in potting mix K,Na,Mg and Ca were consistent with selective adsorption of ions to biochar surfaces.A.Wrobel-Tobiszewska M.Boersma J.Sargison P.Adams B.Singh S.Franks C.J.Birch D.C.Close 2018Journal of Forestry Research2018,29,2:12
3Polyploidy in Cupressaceae:Discovery of a new naturally occurring tetraploid,Xanthocyparis vietnamensis显示文摘While polyploidy(whole-genome multiplication)is generally considered rare in extant gymnosperms(with the exception of Ephedra,Ephedraceae),the occurrence of sporadic polyploid individuals belonging to various genera in the conifer family Cupressaceae has been reported in the literature.In addition,recent studies have revealed that polyploidy is not uncommon in the genus Juniperus(Cupressaceae),with tetraploid and hexaploid individuals reported in individuals collected from wild populations.Given these findings,we undertook a comprehensive screening of ploidy levels in 32 species belonging to the four genera that are phylogenetically closest to Juniperus(i.e.,Callitropsis,Hesperocyparis,Xanthocyparis,and Cupressus),referred to as the CaHXCu complex.In addition,we also determined the ploidy level of two accessions in the poorly studied tetraploid,Fitzroya cupressoides.Using flow cytometry together with published chromosome counts to assign ploidy levels,we show that all species of the CaHXCu complex are diploid except Xanthocyparis vietnamensis,which is tetraploid,with a genome size of 44.60 pg/2 C.This study opens up new opportunities for studying the impact and consequences of polyploidy on the evolution and adaptation of species in Cupressaceae.Perla Farhat Sonja Siljak-Yakovlev Oriane Hidalgo Keith Rushforth Jim ABartel Nicolas Valentin Ilia J.Leitch Robert P.Adams 2022Journal of Systematics and Evolution2022,60,4:0
4DNA库网络:DNA库和离体贮藏机构的国际连网显示文摘由于DNA抽提和固定技术的最新进展,以及全球范围内的重要植物遗传资源的丢失状况促使人们建立了DNA库网络(Royal Botahic Gardens,Kew,London,April,1991)。该网络是一些机构的联合。这些机构致力于冷冻保存热带濒危植物和/或经济植物并保藏基因组DNA。目前,已有五大洲25个国家的40多个机构表示了对DNA库网络感兴趣。分子分类学家可能首先使用该网络。由于世界横向的基因库中有日益增多的基因被鉴定,因此,植物繁育工作者也将使用网络库中的基因培育转基因植株。Robert P.Adams 王颖 1994生物技术通报1994,10,3:0
5NFT和无土基质栽培影响根系的因素显示文摘作物生产上应用的无土基质分为两类:(1)在栽种前已加入肥料的,如泥炭、树皮、锯屑等有机物.(2)包括岩棉、珍珠岩或蛭石等的固体基质和营养液栽培,如深而通气的和浅而循环的营养液栽培(如NFT即营养液膜技术).本文讨论作物对根系环境如温度、湿度、盐浓度、通气性和养分变化的反应.方法将番茄种植于温室的NFT槽中,通过加热或冷却集水池来调节温度;由于集水池和水槽隔热性能良好,根区能获得稳定的温度.水与养分的吸收,以需增加的体积和养分来计算.在NFT,岩棉和深营养液栽培中,所供营养液的养分含量对作物完全适宜.在泥炭袋栽培中,作物已从掺入泥炭的液肥中吸取N、P、K、Fe和B营养元素.结果和讨论(一)根系温度:根系温度对作物生长和肥水吸收影响很大.植株一般在18℃时长得最高。范日清 P.Adams 1994上海蔬菜1994,,4:0
6讨论:应用预扩张和自体脂肪移植行隆乳术:一项临床影像学研究显示文摘近2年来,乳房脂肪移植技术进步飞快;实际上,其手术统计量每年都呈两三倍的速度增长。我们发现很多脂肪移植的支持者对此具有很高的热情,对很多新的方式方法都十分关注。当然,我们对此也很感兴趣,因为我们对脂肪移植非常熟悉。乳房的整形手术是医疗审查十分严格的领域,因此,William P.Adams Jr 石杰(译) 袁继龙(译) 魏峰(译) 高景恒(译) 2011中国美容整形外科杂志2011,22,9:0
