Report of a Novel Case of Anaplastic Olfactory Groove Meningioma and Its Methylation Subtype.

Abstract:

:We report a novel case of a World Health Organization grade 3 anaplastic meningioma arising from the olfactory groove in an 83-year-old woman. Molecular and methylation profiling confirm this lesion to be an NF2 subtype, methylation class intermediate type B meningioma. As most meningiomas in this location are indolent SMO subtype lesions, our report suggests that even though rare, aggressive NF2 subtype meningiomas can also occur along the midline anterior skull base.

  • Glutamate transporter alterations in Alzheimer disease are possibly associated with abnormal APP expression.

    abstract::Recent studies have shown that deficient functioning of glutamate transporters (GTs) in Alzheimer disease (AD) might lead to neurodegeneration. The main objectives of the present study were to determine which GT subtype is most affected in AD and to asses to what extent altered GT function is associated with abnormal ...
