It is well established that the proteolytic processing of the beta-amyloid precursor protein (APP) generates beta-amyloid (Abeta), which plays a central role in the pathogenesis of Alzheimer's disease (AD). In contrast, the physiological role of APP and of its numerous proteolytic fragments and the ...

Chiral Microparticles Supermolecular structures as solid, chiral and flower-like microparticles are obtained from monosaccharide stearoyl esters with variable molecular configurations of sugar rings. Chiral ‘left-handed’ (counterclockwise) and ‘right-handed’ (clockwise) morphologies are induced by d...
