The interaction parameters of MB and BSA and simulated albumin such as partition coefficientκ、 normal binding free energyΔ G、 average binding number n are calculated. The results show that most of MB is in the form of monomer in SDS micelle systems； the main interaction of MB and BSA is of static electric and H-bind force,and that of MB and simulated albumin is only of static electric force.展开更多
The extraction behavior of Fe（Ⅲ）, Cu（Ⅱ）, Co（Ⅱ）, Mn（Ⅱ）, Pb（Ⅱ）, Ni（Ⅱ） and Hg（Ⅱ） by microemulsion Triton X-100 (α-（4-（1,1,3,3-tetramethy（butyl）phenyl）-ω-hydroxy）poly（oxy-1,2-ethanediyl） in ...The extraction behavior of Fe（Ⅲ）, Cu（Ⅱ）, Co（Ⅱ）, Mn（Ⅱ）, Pb（Ⅱ）, Ni（Ⅱ） and Hg（Ⅱ） by microemulsion Triton X-100 (α-（4-（1,1,3,3-tetramethy（butyl）phenyl）-ω-hydroxy）poly（oxy-1,2-ethanediyl） in the presence of （NH4）2SO4 and complexing agents were investigated. The results indicated that the complexes of Fe（Ⅲ） with aluminon were almost completely extracted in HAc-NaAc buffered microemulsion while Cu（Ⅱ）, Co（Ⅱ）, Cd（Ⅱ）, Mn（Ⅱ） and Hg（Ⅱ） were not. Quantitative separation of Fe（Ⅲ）, Co（Ⅱ） and Mn（Ⅱ） were realized. The extraction mechanism by O/W microemulsion has been discussed.展开更多

文摘目的全面、系统地收集国内外照顾者对慢性病患者自我护理贡献的评估工具,总结并分析目前评估工具的构建方法、特点及如何选择,为以后国内开发相关标准化评估工具提供指导。方法遵循范围综述指南,系统检索PubMed、Cochrane Library、Web of Science、Embase、CINAHL、Scopus、中国知网、万方以及维普等数据库,以及1个灰色文献数据库及相关网站。结果最终纳入20篇文献,包含11种评估工具。9个评估工具直接改编自其患者版本,2个评估工具针对照顾者的特点开发。国内目前汉化2个,自主开发1个。纳入的评估工具大多来自意大利,研究对象主要集中在患有多种慢性病以及心力衰竭的患者中。结论目前评估照顾者对慢性病患者自我护理贡献的工具多改编自患者版本,且部分工具信效度有所欠缺。未来医疗科研人员可遵循基于共识选择健康测量工具的标准,依托理论框架或规范指南从二元视角,围绕本国居民的文化特点进一步开发和验证照顾者对慢性病患者自我护理贡献的评估工具。
