高效液相色谱-电感耦合等离子体质谱测定大米粉中的硒形态

建立了高效液相色谱-电感耦合等离子体质谱联用技术(HPLC-ICP-MS)测定大米粉中硒代胱氨酸(SeCys_2)、甲基-硒代半胱氨酸(MeSeCys)、亚硒酸根(Se(Ⅳ))、硒代蛋氨酸(SeMet)、硒酸根(Se(Ⅵ))等5种硒形态的分析方法.采用Hamilton PRP-X100分析柱,以pH 4和pH 6的20 mmol·L~(-1)的柠檬酸溶液辅以少量甲醇为流动相,在梯度洗脱条件下,9 min内可实现5种硒形态完全分离.SeCys_2、MeSeCys、Se(Ⅳ)、SeMet、Se(Ⅵ)的检出限分别为0.88、0.69、1.00、0.90、0.82μg·L~(-1).利用富硒小麦粉标准物质RM8436探讨了不同提取方式的提取效果.最终确定75 mmol·L~(-1) Tris-HCl(pH 7.5)添加XIV蛋白酶和Driselase酶作为提取剂,在37℃振荡提取3 h为大米样品前处理方法.利用该方法分析了富硒地区大米粉中的硒形态,结果表明,大米粉中的硒主要以有机硒形态为主,其中SeMet是最主要的硒形态,占总硒的90%左右.

Psychological Reactance From Reading Basic Facts on Climate Change: The Role of Prior Views and Political Identification

Scholars continue to search for solutions to shift climate change skeptics’ views on climate science and policy. However, research has shown that certain audiences are resistant to change regarding environmental issues. To explore this issue further, we examine the presence of reactance among different audiences in response to simple, yet prominently used, climate change messages. Our results show that emphasizing the scientific consensus of climate change produces reactance, but only among people who question the existence of climate change. Moreover, adding political identification to the model as an additional moderating variable shows the increases in reactance occur among Republicans who question the existence of climate change. Finally, our results show that reactance to climate change messaging may lead to backfiring effects on important outcomes tied to climate change such as risk perceptions, climate change beliefs, and support for mitigation policies.
