中世纪英国诗人约翰·高厄在他的盎格鲁-诺曼语诗歌《人类之镜》中进行社会批判和道德考量。本文旨在回归语境,研究高厄如何采用拟人化寓言、等级讽刺文和训诫文等形式阐释罪恶和美德的关系,表达对道德丧失的愤怒,并在自我反思的基础上扩大道德说教范围,达到向社会说教之效,与同时代文本构成互文。在14世纪70年代英国内外交困的境况下,高厄为个人救赎和社会发展谏言,表达了对精神家园和社会风气的道德召唤。

Dietary phosphatidylcholine (PC) is an ideal source of bioactive lipids showing efficacy to alleviate non-alcoholic fatty liver disease (NAFLD). In this study， the lipidomic profiles of nonalcoholic steatosis in mice and HepG2 cells treated with PC isolated from eggs (EPC) and soybean (SPC) were evaluated. EPC and SPC could significantly ameliorate fatty liver disease by down-regulating triglyceride (TG) and diglyceride (DG) levels. Remarkably， EPC exhibited better performance in regulating the hepatic lipid profile leading to decreased PC and TG， ceramides， phosphatidylethanolamine and phosphatidylserine levels. A total of 117 and 20 lipid biomarkers in liver and HepG2 cells involved in glycerophospholipid metabolism were screened out， respectively. The regulatory mechanism of EPC may be attributed to a decrease in the expression of ACACA and SREBP-1c. EPC， via suppressing lipogenic gene expression， which was superior to that of SPC in alleviating nonalcoholic steatosis. Overall， EPC and SPC attenuated HFD-induced NAFLD by improving the hepatic lipid profile. The more significant effect observed with EPC may be attributed to its modulation of glycerophospholipid metabolism.

Ligand engineering for well-defined gold nanoclusters(Au NCs) is getting more extensive attention. Organizing the Au-ligand interfaces on gold NCs can achieve the structural and functional control. This review focuses on the Au-ligand interfaces including gold-phosphorus(Au-P), gold-sulfur(Au-S), gold-selenium(Au-Se), gold-carbon(Au-C), and gold-nitrogen(Au-N), derived from the bonding between Au atoms and the different ligands(e.g., organic phosphine, thiolate, selenolate, alkynyl,n-heterocyclic carbene and nitrogenous ligands). The formation mechanism of Au-ligand interfaces is well discussed. In addition, the effects of Au-ligand interfaces on the stability, optical property, and catalysis are also presented. We hope the advances in this research area can boost the development of Au NC sciences.

为考察糖基化接枝及酶法相结合的复合改性对于大豆分离蛋白功能性质的影响,以提高接枝度及产物乳化能力等功能性质为主要指标,制备大豆分离蛋白与麦芽糊精糖基化产物,随后采用中性蛋白酶对该产物适度酶解,得到不同水解程度的糖基化产物水解物,研究产物的乳化能力、起泡性能及抗氧化能力的变化。实验结果表明:经过接枝及适度酶解复合改性后,大豆分离蛋白的乳化能力、起泡性能及DPPH自由基清除能力均有了较大的提高,但深度的酶解有可能破坏蛋白的空间结构,降低粘度从而影响功能性质的发挥。
