Alzheimer's disease (AD) is the most common neurodegenerative disorder pathologically characterized by amyloid-beta (Aβ) plaques and neurofibrillary tangles. The aggregation of Aβ precedes tau pathologies in AD; however, the causal relation between the two pathologies and the mechanisms by which

Previous studies suggest that Alzheimer's disease (AD) neurobiology could not be explained solely by an increase in β-amyloid levels. Recently, it has been proposed that alterations in brain cholesterol metabolism may contribute to the pathogenesis of AD. In the present

The reaction of PSCl3 with Pr(i)2NH at 60 degrees C affords the disubstitution product (Pr(i)2N)2P(S)Cl without first forming the monosubstitution product Pr(i)2NP(S)Cl2; a P(III) compound (possibly PCl3) generated in situ seems to be a crucial intermediate.
