GFAP Mutations in Astrocytes Impair Oligodendrocyte Progenitor Proliferation and Myelination in an hiPSC Model of Alexander Disease

Li Li, E Tian, Xianwei Chen, Jianfei Chao, more

Cell Stem Cell > 2018 > 23 > 2 > 239-251.e6

Alexander disease (AxD) is a leukodystrophy that primarily affects astrocytes and is caused by mutations in the astrocytic filament gene GFAP. While astrocytes are thought to have important roles in controlling myelination, AxD animal models do not recapitulate critical myelination phenotypes and it is therefore not clear how AxD astrocytes contribute to leukodystrophy. Here, we show that AxD patient...

Evaluation of optimized bio-asphalt containing high content waste cooking oil residues

Daquan Sun, Guoqiang Sun, Yuchuan Du, Xingyi Zhu, more

Fuel > 2017 > 202 > C > 529-540

Waste cooking oil residues (WCORs)-based bio-asphalt is a potential substitute for petroleum asphalt. However, asphalt binders with a high WCOR content indicates a low rheological property, leading to a limited WCOR mixed content (usually no more than 10wt% of asphalt binder). This study aims to prepare an eco-friendly bio-asphalt with a high WCOR content. Based on the formula uniform design method,...
