| 4 | 确定表达序列标签微阵列的对照参数以分析刚地弓形虫强毒株及弱毒株(英文)显示文摘目的 在应用微阵列 c DNAs分析刚地弓形虫强、弱毒株差异前 ,实验的对照 ,例如 ,DNA的含量、阳性及阴性杂交、基线的及不同的基因表达 [微阵列表达序列标签 (ESTs)、c DNAs]等 ,均在本研究中加以确定 ,从而确保数据处理的计算机化及精确性。 方法 自弓形虫 RH株及弓形虫 ME49株速殖子提取 RNA作为探针。PCR法扩增的 ESTs及杂交对照采用 Micro Grid TM机点样于载玻片上。经杂交后的玻片以 Scan Array30 0 0 TM扫描并对结果进行分析。 结果 DNA含量可在 5 ng/ μl及 2 5 0 ng/ μl之间变化 ,最佳值为 5 0 ng/μl;为分析非特异性杂交的影响必须同时设置阴性对照 ;对结果的计算机化处理需要几个基线的不同的基因表达作为对照。 结论 当采用适当的对照、重复及完整的 EST后 。 | 李爽 甘绍伯 Christopher P Reitter Jennifer M Fitzpatrick James W Ajioka | 2001 | 中国寄生虫病防治杂志2001，14，3： | 0 |
| 5 | Nitrogen regulation by natural systems in“unnatural”landscapes:denitrification in ultra-urban coastal ecosystems显示文摘Dense cities represent biogeochemical hot spots along the shoreline,concentrating fixed nitrogen that is subsequently discharged into adjacent coastal receiving waters.Thus,the ecosystem services provided by natural systems in highly urban environments can play a particularly important role in the global nitrogen cycle.In this paper,we review the recent literature on nitrogen regulation by temperate coastal ecosystems,with a focus on how the distinct physical and biogeochemical features of the urban landscape can affect the provision of this ecosystem service.We use Jamaica Bay,an ultra-urbanized coastal lagoon in the United States of America,as a demonstrative case study.Based on simple areal and tidal-based calculations,the natural systems of Jamaica Bay remove~24%of the reactive nitrogen discharged by wastewater treatment plants.However,this estimate does not represent the dynamic nature of urban nitrogen cycling represented in the recent literature and highlights key research needs and opportunities.Our review reveals that ecosystem-facilitated denitrification may be significant in even the most densely urbanized coastal landscapes,but critical uncertainties currently limit incorporation of this ecosystem service in environmental management. | Bernice R.Rosenzweig Peter M.Groffman Chester B.Zarnoch Brett F.Branco Ellen K.Hartig James Fitzpatrick Helen M.Forgione Adam Parris | 2018 | Ecosystem Health and Sustainability2018，4，9： | 0 |
