    Amyloid and tau in the brain in sporadic Alzheimer’s disease: defining the chicken and the egg

    No full text
    In the October 2013 issue of Acta Neuropathologica there were three very interesting articles on: Amyloid or tau: the chicken or the egg? In the first article, David Mann and John Hardy argued that the deposition of aggregated amyloid β (Aβ) protein in the brain is a primary driving force behind the pathogenesis of Alzheimer’s disease with tau pathology following as a consequential or at least a secondary event. In the communication that followed, Braak and Del Tredici presented the contrary argument with accumulation of tau protein as the primary event in sporadic Alzheimer’s disease. Attems and Jellinger questioned the concept of a chicken and egg and suggested that the majority of cases of age-associated dementia are not caused by one single primary pathological mechanism

    Rb2Sb4O11

    The title compound, dirubidium tetraantimonate(V), Rb2Sb4O11, has been synthesized by flux reaction. It is isotypic with known A2Sb4O11 (A = K, Cs) structures and consists of an (Sb4O11)2- skeleton and two Rb atoms as charge-compensating cations. Distorted SbO6 octahedra share edges and corners, resulting in a layered assembly. Alternate stacking of the layers along the c axis leads to the formation of tunnels. The Rb+ ions, surrounded by nine and ten O atoms, respectively, are located in these tunnels. Some atoms in the structure are on special positions of m symmetry (two Sb atoms, both Rb atoms and four O atoms) and 2 symmetry (one O atom
