酪素基rGO复合乳液的制备及其阻燃性能

为制备具有增强阻燃效果的皮革涂饰材料,首先以天然石墨为原料,采用Hummers法制备氧化石墨烯(GO),并采用NaBH4对其进行还原得到还原氧化石墨烯(rGO).通过FTIR,XRD和TEM等对其进行表征.结果表明,成功制备了rGO纳米材料.随后,采用物理共混法将rGO引入天然蛋白质酪素体系,制备酪素基rGO复合乳液并将其应用于皮革涂饰,对涂饰后革样的阻燃性能、力学性能和耐干湿擦性能进行测试.结果表明,当rGO的含量为酪素体系溶质质量的0.5％时,与未含rGO的酪素体系相比,涂饰后革样的燃烧速率下降47.2％,极限氧指数(LOI)由24.2％增加至26.3％,热释放速率(HRR)下降53.1％,总热释放速率(THR)也有所降低.rGO的引入对涂饰后革样的力学性能和耐干湿擦性能影响不大.

Molecular Characteristics of Amyloid Precursor Protein (APP) and Its Effects in Cancer

Amyloid precursor protein (APP) is a type 1 transmembrane glycoprotein, and its homologs amyloid precursor-like protein 1 (APLP1) and amyloid precursor-like protein 2 (APLP2) are highly conserved in mammals. APP and APLP are known to be intimately involved in the pathogenesis and progression of Alzheimer’s disease and to play important roles in neuronal homeostasis and development and neural transmission. APP and APLP are also expressed in non-neuronal tissues and are overexpressed in cancer cells. Furthermore, research indicates they are involved in several cancers. In this review, we examine the biological characteristics of APP-related family members and their roles in cancer.
