Disease associated pathological aggregates of alpha-synuclein (αSynD) exhibit prion-like spreading in synucleinopathies such as Parkinson's disease (PD) and dementia with Lewy bodies (DLB). Seed amplification assays (SAAs) such as real-time quaking-induced conversion (RT-QuIC) have shown high diagnostic sensitivity and specificity for detecting proteopathic αSynD seeds in a variety of biospecimens from PD and DLB patients. However, the extent to which relative proteopathic seed concentrations are useful as indices of a patient's disease stage or prognosis remains unresolved.

Article Synopsis
  • Gliosarcoma is a rare brain tumor in cats that has not been previously associated with changes in the hippocampus, but a case was reported involving a cat with complex partial seizures and orofacial symptoms.
  • A 16-year-old cat showed symptoms like disorientation and ataxia, and MRI revealed a tumor in the right piriform lobe along with abnormalities in the hippocampus.
  • Due to insufficient biomaterial, additional testing for associated conditions was not conducted, but the presence of gliosarcoma suggests that similar cases warrant MRI and antibody testing for proper diagnosis.

Ditopic bis-pyrazolylpyridine ligands usually react with divalent metal ions (M) to produce dinuclear triple-stranded helicates [ML] or, π⋯π interactions, dimers of monoatomic complexes ([ML]). The introduction of an additional benzene ring at each end of ligand L increases the number of aromatic contacts within the supramolecular aggregate by 40%, driving the self-recognition process in an irreversible manner. Consequently, the mixing of new bis-pyrazolylquinoline L2 with FeX salts leads to crystallization of the tripartite high-spin assemblies (X@[Fe(L2)]) (X = Cl, Br or I).
