EU Policy‐Making in the Digital Age: Major Trends and Insights From Public Policy Research
European Policy Analysis, EarlyView.ABSTRACT Has digitalization changed policy‐making dynamics at the European Union (EU) level? To investigate this issue, this article presents a scoping review of the literature on EU digital policy‐making. While much scholarship adopts a ‘Governance’ approach, two conceptually rich strands emerge: critical approaches, and digital sovereignty.

Regulation of PI3K and MAPK inhibitors on the activity of FOXO1 and their effect on biological behavior of GIST-T1 gastric stromal tumor cell lines [PDF]
, 2015 胃肠道间质瘤（gastrointestinalstromaltumors,GISTs）是消化道最常见的间叶组织肿瘤。目前普遍认为GISTs起源于向cajal细胞分化的原始间叶细胞或幼稚干细胞，具有多向分化特征，可以向平滑肌、神经分化或不定向分化，是一种具有恶性潜能的胃肠道肿瘤，但其确切起源尚不明确。其发病率为1～2/10万人口,似乎正逐渐增加。近年来有研究表明，PI3K（磷脂酰肌醇-3-激酶）和MAPK（丝裂原活化蛋白激酶）信号通路活性在胃肠道间质瘤显著增高 ...
