Efficacy and safety of the contralateral approach to vascular lesions in the vertebral artery: patient series.

Background: Endovascular treatment is preferred over microsurgical clipping for intracranial aneurysms in the posterior circulation. However, access to lesions, particularly those in the regions of the vertebral artery (VA) and the posterior inferior cerebellar artery (PICA), is technically challenging in terms of the vessel diameter of the ipsilateral VA or the branching angle of the PICA.

Observations: Nine cases of intracranial aneurysms in the region of the PICA, which were endovascularly treated with an approach beyond the vertebrobasilar junction (VBJ) from the contralateral VA in the last 4 years, are described herein.

Adaptation of Magnified Analysis of the Proteome for Excitatory Synaptic Proteins in Varied Samples and Evaluation of Cell Type-Specific Distributions.

Growing evidence suggests a remarkable diversity and complexity in the molecular composition of synapses, forming the basis for the brain to execute complex behaviors. Hence, there is considerable interest in visualizing the spatial distribution of such molecular diversity at individual synapses within intact brain circuits. Yet this task presents significant technical challenges.
