Comparative study on the catalytic properties of amino-functionalized silica ma...
Liu,Yan; Zhao,Guoming; Zhu,Wanchun; Wang,Jing; Liu,Gang; Zhang,Wenxiang; Jia,MingjunA series of hybrid mesoporous MCM-41 materials containing different amino groups (such as 3-aminopropyl (AP-), (2-aminoethylamino)propyl (AAP-), or [2-(2-aminoethylamino)ethylamino]propyl (AEP-) group) were prepared by a post-grafting method, and characterized by means of X-ray powder diffraction (XRD), N2 adsorption, Fourier transform-infrared spectroscopy (FT-IR) and temperature-programmed desorption of CO2 (...
Iron: The Redox-active Center of Oxidative Stress in Alzheimer Disease
Castellani, Rudy; Moreira, Paula; Liu, Gang; Dobson, Jon; Perry, George; Smith, Mark; Zhu, XiongweiAbstract Although iron is essential in maintaining the function of the central nervous system, it is a potent source of reactive oxygen species. Excessive iron accumulation occurs in many neurodegenerative diseases including Alzheimer disease (AD), Parkinson’s disease, and Creutzfeldt-Jakob disease, raising the possibility that oxidative stress is intimately involved in the neurodegenerative process. AD in par...
