Background By investigating that (i) all-trans retinoic acid (ATRA) affects human retinal pigment epithelium (RPE) in expressing and secreting transforming growth factor (TGF)-β2 and (ii) U73122 (phospholipase C inhibitor) and SQ22536 (adenylyl cyclase inhibitor) regulate the ATRA-induced secretion of TGF-β2 in human RPE, we sought to interpret the signaling pathway of ATRA in promoting the development...
Based on the Keggin-type polyoxometalate and quaternary phosphonium salt, the (MePh3P)n-POMKeggin compounds were synthesized via one-step mechanochemical process at room temperature. It showed the advantages of convenient operation, lower cost, less pollution, and mass production. Wonderfully, the morphology of compounds presented a strong dependence on the number of crystal water in the source heteropoly...

A topic often consists of several events, and people are interested in the whole evolution of a topic along a timeline. This requests for finding and identifying the dependent relationships between events. In order to understand the whole evolution of a topic effectively,...
It is important to study the mutual relationship and coordinated development of urbanization and urban employment. By the means of impulse response analysis and panel data regression, this paper makes an empirical analysis of the relationship between urbanization and urban employment. Time series analysis results show that the increase in the urbanization ratio and the scale of urban employment promote...
