1中国南部四背景地区春季大气碳质气溶胶特征与来源显示文摘春季分别同时在中国南方4个背景地区(海南尖峰岭、香港鹤嘴、浙江临安和云南腾冲)进行大气加密观测实验,并分析其大气中PM2.5质量浓度及其碳质颗粒组分(有机碳(OC)、元素碳(EC)和左旋葡聚糖).结果表明,各区域背景站点由于受不同污染源及传输过程影响而呈现出不同的特征:西南部腾冲站点与东部临安站点由于分别受到生物质燃烧和化石燃料燃烧等一次污染源的主导影响,而形成高OC、EC水平特征,且经受体示踪物方法估算腾冲站点受生物质燃烧对其OC的贡献均值可达到73%;尖峰岭站点由于二次污染及活跃的生物活动的共同作用,表现了高OC/EC比值及低碳质颗粒物浓度的特征,而鹤嘴站点则主要受海洋气团影响呈现出低碳质颗粒浓度与两两呈高度相关的特点,反映了其所在区域春季的背景特征.罗运阔 陈尊裕 张轶男 Engling Guenter 张智胜 桑雪芳 王雪梅 2010中国环境科学2010,30,11:19
2北京市大气气溶胶中糖类化合物的组成及来源显示文摘采用高效阴离子交换色谱-脉冲安培检测(HPAEC-PAD)分析方法,对北京城区PM2.5和PM10中糖类化合物进行定量分析.在北京大气气溶胶中共检出14种糖类化合物,分为脱水糖、糖和糖醇共3大类.脱水糖包括左旋葡聚糖、甘露聚糖和半乳聚糖;糖包括葡萄糖、果糖和海藻糖;糖醇包括阿拉伯糖醇、甘露糖醇、丙三醇、苏糖醇、2-甲基丁四醇(2-甲基苏糖醇和2-甲基赤藓糖醇)、木糖醇和肌醇.脱水糖来源于生物质燃烧,秋冬季节的浓度水平明显高于春夏;而来源于生物源排放的糖和糖醇,冬季浓度水平明显低于其它季节.PMF源解析结果表明,北京大气气溶胶中糖类化合物的来源主要可以分为6类,包括生物质燃烧、异戊二烯SOA、土壤悬浮、真菌孢子、花粉及丙三醇富集源.梁林林 Guenter Engling 段凤魁 马永亮 程远 杜祯宇 贺克斌 2015环境科学2015,36,11:13
3通过手机进行健康干预报告的指南:移动医疗证据报告和评估检查表显示文摘为提升移动医疗(mHealfh)干预报告的完整性,WH0mHealth技术证据评审小组开发了mHealth证据报告和评估(mERA)检查表。该mERA开发过程包括成立专家组,提出合适的路径,召集全球专家评审小组以研发检查表,并进行小规模测试。制定这些标准的指导原则是以最少的信息集合来定义mHealth干预是什么(内容),在哪儿应用(环境),如何应用(技术特性),以便支持干预的可重复性。该文档由16个选项表构成,附带各项内容的详细解释和说明,以及说明性的报告范例。通过广泛征求意见,我们希望该指南的应用可规范mHealth证据报告的质量,间接提升mHealth证据的质量。Smisha Agarwal Amnesty E LeFevre Jaime Lee Kelly L'Engle Garrett Mehl Chaitali Sinha Alain Labriquel 沈锡宾(译) 涂宏钢(校) 2016英国医学杂志中文版2016,19,11:6

6Endothelial adhesion of synchronized gastric tumor cells changes during cell cycle transit and correlates with the expression level of CD44 splice variants显示文摘AIM: To study adhesion capacity and CD44 expression of human gastric adenocarcinoma MKN45 cells at different stages of a first cell cycle.METHODS: MKN45 cells were synchronized by aphidicolin and assayed for adhesion to an endothelial cell (HUVEC)monolayer. Surface expression of CD44 and CD44 splice variants on MKN45 cells was evaluated by flow cytometry.Functional relevance of CD44 adhesion receptors was investigated by blocking studies using anti CD44 monoclonal antibodies or by hyaluronan digestion.RESULTS: Adhesion of MKN45 to HUVEC was increased during G2/M transit, after which adhesion returned to baseline levels with cell cycle completion. In parallel, CD44splice variants CD44v4, CD44v5, and CD44v7 were all upregulated on MKN45 during cell cycle progression with a maximum effect in G2/M. The function of CD44 surface receptors was assessed with specific receptor blocking monodonal antibodies or removal of hyaluronan by digestion with hyaluronidase. Both strategies inhibited tumor cell adhesion to HUVEC by nearly 50%, which indicates that MKN45-HUVEC-interaction is CD44 dependent.CONCLUSION: CD44 expression level is linked to the cell cycle in gastrointestinal tumor cells, which in turn leads to cell cyde dependent alterations of their adhesion behaviour to endothelium.Anton Oertl Jens Castein Tobias Engl Wolf-Dietrich Beecken Dietger Jonas Richard Melamed Roman A.

11论美国基础教育财政不平等的根源显示文摘近年来,在美国基础教育财政论坛中占主导地位的有两大议题。其一,政治保守派主要关心过去二十年来教育经费支出庞大,联邦政府通过下拨教育专款实现和完成具体目标和项目等手段不断插手教育事业。其二,政治开明派则更注重审视各州之间、全国14000个学区之间、甚至一个学区里的每所学校之间教育经费的显著差异;他们呼吁提高最低学区的经费水平以缩小不平衡性,因此,他们所提倡的是增加教育总投入。介于这两派相反意见之间,教育研究人士的争论是增加教育投入是否能够改善学生的学业成绩。David Engles 1999上海教育科研1999,,1:2
