Is psychosis of Alzheimer 's disease associated with elevated muscarinic M2 binding in the cortex?
This study suggests a role for M(2) receptors in the psychosis of AD and may provide the rationale for treatment of behaviorally perturbed patients with AD with cholinomimetics and M(2) antagonists.
The clinical behaviour of SPT in the paediatric population is similar to its adult counterpart. Complete surgical resection is essential. PDX1 and Sox9 proteins are exclusively expressed in the cytoplasmic compartment in SPT, suggesting overexpression of the corresponding genes linked to beta-catenin mutations. These findings favour the hypothesis that SPT originates from transformation of normally quiescent pancreatic stem cells.
