石蜡包埋淋巴组织三种微量DNA提取方法的比较

Zhongguo shiyan zhenduanxue, 2006
目的为寻找一种高效、简便、实用的石蜡组织中DNA提取方法,本研究比较了三种不同的DNA提取方法对DNA质量的影响。方法选取淋巴相关组织的蜡块21例。三种DNA提取方法分别是简单消化煮沸法,酚/氯仿提纯法和试剂盒法。通过提取DNA的浓度和纯度、PCR扩增保守序列β-globin等方法,比较三种DNA提取方法的优劣。结果试剂盒法提取样品OD260/OD280平均比值位于1.61.8之间;提纯法位于1.31.5之间;简单消化煮沸法位于1.21.3之间。三种方法中,试剂盒法提取的DNA最为稳定 ...

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

Conservation Biology, EarlyView.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Spatial identification of areas suitable for other effective area‐based conservation measures in the European Union

Conservation Biology, EarlyView.
Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.
