Policy &Internet, Volume 18, Issue 2, June 2026.ABSTRACT AI‐generated images have become so good in recent years that individuals often cannot distinguish them from ‘real’ images. This development, combined with the rapid spread of AI‐generated content online, creates a series of societal risks. Watermarking, a technique that involves embedding information within the content to indicate their AI ...

Effects of ApoE Isoforms Expression on Brain ApoE Lipidation and Amyloid-β Accumulation [PDF]
, 2015 在编码人三种不同apoE蛋白亚型（E2、E3和E4）的APOE等位基因（ε2、ε3和ε4）中，APOEε4等位基因是阿尔茨海默病（Alzheimer’sdisease，AD）最重要的遗传风险因子，APOEε2等位基因则具有保护作用。鉴于apoE蛋白亚型对基于调节apoE蛋白表达的AD治疗可能会有不同的影响，我们通过在人APOE基因定位替换（Targetedreplacement，TR）小鼠脑中过表达不同的人apoE亚型，研究脑中表达不同apoE亚型对apoE脂化和β-淀粉样蛋白（Amyloid-β，Aβ）

Expression of IRG47 and Generation of Rabbit Polyclonal Antibody Against IRG47 [PDF]
, 2015 IRG（Immunity-relatedGTPases）是干扰素γ诱导的免疫相关GTP蛋白，最先在脊椎动物中被发现。IRG蛋白在调节细胞内的病原体先天的抵抗力有着很重要的作用。在动物感染了细菌、原生动物和病毒的时候或者干扰素诱导，IRG蛋白表达量会升高。IRG蛋白在老鼠、兔子、狗、斑马鱼和人中都有表达。其中已经有研究表明，老鼠IRG蛋白在抵抗病原体和细菌作用上起到很重要的作用。IRG47属于IRG蛋白家族成员，但IRG47蛋白的性质和功能还没有被研究。 本文构建了IRG47的表达载体 ...
