1二氧化硫对墨西哥豆瓢虫的影响显示文摘空气污染对害虫的影响,国内尚无研究报道。本文报道了作者在美国农业研究中心植物胁迫实验室进行的部分工作。实验结果表明,在0.30ppmSO_2的作用下,墨西哥豆瓢虫(Epilachna varivestis)的取食量和蛹重增加;与未受污染的寄主植物相比,豆瓢虫偏食受污染的植物;而且有嗜食含较高糖分寄主植物的倾向;在污染空气中长成的成虫可消耗更多的植物物质。吴亚 Edward H.Lee Edward M. Barrows 1989生态学报1989,9,4:9
2A Comparative Analysis of Four Kinds of Polysaccharides Purified from Furcellaria lumbricalis显示文摘Four kinds of polysaccharides (FA, FB, FC and FD) were extracted and purified from a red alga Furcellaria lumbri-calis. Their monosaccharide composition, average molecular mass (Mw) and structural feature were determined by gas chromatog-raphy (GC), high performance gel permeation chromatography (HPGPC) and Fourier transform infrared spectroscopy (FTIR), respectively. The results showed that FA and FB were composed of galactose (Gal), 3,6-anhydro-galactose (AnG) and 4-sulfated-galactose (G4S), which were structurally similar to β-carrageenan and κ-carrageenan. FC was composed of sulfated galactose and small amount of AnG, indicating that it was a hybrid-sulfated galactan. FD was composed of α-1, 4-glucose and belonged to floridean starch. The respective yields of FA, FB, FC and FD were 4.84%,33.74%,8.76% and 13.5%, and the cor-responding Mw were 537 kD, 432 kD, 513 kD and 51 kD respectively. Owning to its high content ( >60%) of polysaccharide, F. lumbricalis will be a good source of marine sulfated polysaccharide and shows its potential utilization in food and medicine.BARROW Colin 2007Journal of Ocean University of China2007,6,1:8
3烧伤治疗历史的回顾与展望显示文摘机体损伤涉及临床医学多学科,烧伤为平时和战时常见的一种组织损伤,它的修复包括维持机体的内环境稳定和不同深度的组织损伤后的修复全过程。近50年来,我国现代烧伤临床和研究发展迅速,业绩显著。虽然有不少创新成就,但由于对外交流还不够,尚未达到足够影响力,有些工作还不被人所知,我们应当一方面加强对外学术交流,扩大影响,另一方面,随时关注国际动态,做到知己知彼。为了使我国广大临床工作者系统了解美国烧伤临床和研究的概况,本刊组织了数位专家翻译由美国著名的烧伤专家David Heradon主编,近百余位专家撰写的Total Burn Care(第二版)2002年出版的美国最权威的烧伤治疗一书,将在本刊连续刊登,供同道们参考,该文有许多值得我们思考的地方。学诸专家之长,结合我国国情,走自己的创新之路,把我国烧伤治疗和研究推向新水平,为丰富国际烧伤医学宝库而奋斗。Steven Thomas Roberte Barrow David N Herndon 孙永华 2007中华损伤与修复杂志(电子版)2007,2,3:6
4荧光光谱法研究蒜头果蛋白与金属离子的相互作用显示文摘蒜头果蛋白(malanin)是从云南、广西特有植物蒜头果中分离纯化出的一种新的、具有抗肿瘤活性的糖蛋白。用荧光光谱法研究了Cu2+,Ag+和Ca2+对malanin和apo-malanin溶液(经EDTA透析脱去金属离子后的脱金属蛋白)荧光强度的影响。结果表明,Cu2+对malanin和apo-malanin荧光均有明显的静态猝灭现象,其离解常数Kd分别为2.37×10-4和2.66×10-4 mol·L-1;Ag+对malanin的荧光强度变化不大,但对apo-malanin荧光强度却有明显的静态猝灭现象,其离解常数Kd为2.37×10-4 mol·L-1;而Ca2+对malanin和apo-malanin荧光强度均无明显变化,说明Ca2+对维持malanin分子天然构象具有重要作用。袁燕 张薇 戴建辉 刘晓芳 王红斌 Colin J Barrow 杨文荣 2014光谱学与光谱分析2014,34,12:5

6SDS-PAGE电泳法测定蒜头果蛋白的相对分子质量显示文摘蒜头果蛋白(malanin)是从广西、云南特有植物蒜头果中分离、纯化出的一种新的、具有抗肿瘤活性的植物蛋白质.采用变性十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)测定malanin的相对分子质量.结果表明,malanin是一种双链蛋白质,由A、B 2条肽链通过二硫键连接而成,其相对分子质量约为65.94×103.方法具有简单、快速、直观的特点.袁燕 王红斌 BARROW Colin J 杨文荣 2015云南民族大学学报(自然科学版)2015,24,2:4
7烧伤治疗的历史显示文摘烧伤的治疗已有超过3500年的历史。在尼安德特人洞穴里发现的壁画是最早的直接性证据。对于烧伤的治疗,公元前1500年,埃及铁匠的纸莎草纸文件材料中提到使用树脂和蜂蜜混合成的药膏来治疗;在公元前600年,中国人使用的是酊和从茶叶中榨取的汁;之后将近两百年,张杨杨 贾赤宇 Barrow RE Herndon DN 2012中华损伤与修复杂志(电子版)2012,7,4:4
8Ecosystem service delivery in Karst landscapes: anthropogenic perturbation and recovery显示文摘Covering extensive parts of China, Karst landscapes are exceptional because rapid and intensive land use change has caused severe ecosystem degradation within only the last 50 years. The twentieth century intensification in food production through agriculture has led to a rapid deterioration of soil quality, evidenced in reduced crop production and rapid loss of soil. In many areas, a tipping point appears to have been passed as basement rock is exposed and 'rocky desertification' dominates. Through the establishment of the 'Soil processes and ecological services in the karst critical zone of SW China'(SPECTRA)Critical Zone Observatory(CZO) we will endevaour to understand the fundmental processes involved in soil production and erosion, and investigate the integrated geophysical-geochemical-ecological responses of the CZ to perturbations. The CZ spans a gradient from undisturbed natural vegetation through human perturbed landscapes.We seek to understand the importance of heterogeneity insurface and below-ground morphology and flow pathways in determining the spatial distribution of key stocks(soil,C, vegetation, etc.) and their control on ecosystem service delivery. We will assess the extent to which the highly heterogeneous critical zone resources can be restored to enable sustainable delivery of ecosystem services. This paper presents the CZO design and initial assessment of soil and soil organic carbon stocks and evidence for their stability based on caesium-137(^(137) Cs) data.Timothy Quine Dali Guo Sophie M.Green Chenglong Tu Iain Hartley Xinyu Zhang Jennifer Dungait Xuefa Wen Zhaoliang Song Hongyan Liu Heather Buss Timothy Barrows Richard Evershed Penny Johnes Jeroen Meersmans 2017Acta Geochimica2017,36,3:3
