Effect of ellagitannins gut microbiota metabolites ellagic acid (EA) and urolithin A-urolithin D (UroA-UroD) on human serum albumin (HSA) glycation were firstly evaluated in this research. The inhibition mechanisms were investigated by methylglyoxal (MGO) trapping and radical scavenging ability assays， docking studies and Nano LC-Orbitrap-MS/MS technology. Results indicated that the inhibition of urolithins on HSA glycation was highly positive correlated with the number of phenolic hydroxy groups. Addition of UroD and EA could effectively enhance the content of free amino group， suppress dicarbonyl compounds and advanced glycation end-products (AGEs) formation， alleviated tryptophan and protein oxidation， inhibited HSA amyloid-like aggregation. They could also trap MGO and scavenge DPPH· and ABTS·+. Molecular docking indicated that EA and UroA-UroD interact with HSA mainly through hydrogen bound and hydrophobic interaction， among which two or three hydrogen bonds were formed. The number of glycation sites were reduced from 11 to 10， 10， 7， and 10， respectively， when 90 μmol/L of EA， UroA， UroC and UroD were added. However， weak inhibition was observed on UroA and UroB. These findings can provide scientific evidence for the application of ellagitannins-rich foods in alleviating diabetic complications.

庄子“逍遥游”与奥克肖特“游戏”之间蕴含多维的可跨文化对话的思维交汇点。二人之“游”皆为向内探索精神自由、生命意义的非正统意向。前者以“游心”出离自我、觅解“本真”世界,后者以“游戏”揭橥自我、创设与世界相融贯的理解范式。“无用为用”的批判性运思与审慎节制的“平稳之舟”一同构成“游”之权宜手段。以人的自我价值为取向的“不言之教”与“谈话之教”是“游”在教育中的同质异构。庄奥“游”之“和”的教育蕲向即在于借助疗愈实践主体思维缺陷的“诗性语言”,摹绘实践主客体交融互通、和谐共生之意境,以“规律性秩序感”和“成和之心”的联动,实现“和合教育”的共美文化图景。

奥克肖特的《政治中的理性主义》中隐含着他对道德准则和道德教育的哲学思考,其中《巴别塔》一文影射的道德教育理念构成其教育哲学的重要一环。道德教育是基于社会生活的教育,旨在规范、调整人的思想和行为。礼俗道德与完善道德的关系是道德生活的重要问题。奥克肖特将礼俗道德解析为情感与习惯的道德,又视完善道德为改良与规整的道德。近代西方社会生活的泥淖在于礼俗道德与完善道德的定位失衡,表现为完善思维优先于道德实践,通过改善、优化行为规范准则来弱化礼俗传统的承续价值。奥克肖特一边创构沉思和想象的礼俗性道德教育,一边勾勒礼俗传统与完善思维联结共生的道德教育的可能形态。其道德教育的愿景旨在将礼俗传统和行为习惯复归为社会发展所需的内源性条件,以愉悦的情感暗示去牵制、淡化完善思维的极端理性,从对技术规则与应用效益的鼓吹闭环中突围出来,绘制融洽的公共关系道德图谱。

A two-terminal self-powered optoelectronic structure could mimic synaptic functions of a human brain synapse unit(Figure 1(a)) based on the photovoltaic effects [1], demonstrating the potential for decreasing energy consumption for future computing. However, current self-powered optoelectronic synaptic devices face issues of stability and cost,which mainly arise from noble metal electrodes and independent hole transport layers used in these structures. Substituting low-cost carbon for these metal electrodes and carrier transport layers may promise to solve these challenges.

Radical-involved allylation reactions have emerged as a powerful platform for construction of carbon-carbon and carbonheteroatom bonds, facilitating the strategic incorporation of diverse allyl moieties. Nevertheless, this burgeoning field still faces ongoing challenges, including limitations of radical precursors and coupling partners, and difficulties in achieving enantiocontrol. Herein, we report for the first time a highly enantioselective radical allylation involving β-keto esters with vinyl cyclopropanes utilizing a synergistic dual photoredox/nickel catalysis under visible light irradiation. The mild and redox-neutral catalytic protocol demonstrates an extensive substrate compatibility and good functional tolerance, providing access to enantioenriched β-keto esters featuring quaternary α-stereocenter with good yields and high enantioselectivities. Preliminary mechanistic studies have uncovered that the success of the reaction hinges on the dual roles of nickel catalyst, including in situ formation of photoredox sensitive substrate/Ni complex and the ensuing asymmetric radical addition step.
