Impact of Adjuvant Radiotherapy on Recurrence of Surgically Treated Atypical Meningiomas and Retrospective Analysis of Prognostic Factors.

Aim: The role of adjuvant radiotherapy after surgery for atypical meningiomas remains controversial. The present study was designed to investigate the recurrence rate of atypical meningiomas after surgery (with or without adjuvant radiotherapy) and determine which factors were related with recurrence.

Material And Methods: Data obtained from 83 patients who underwent surgery and histopathologically diagnosed with atypical meningioma at a single institution between January 2009 and June 2019 were retrospectively reviewed.

Distribution of Aquaporin-4 channels in hippocampus and prefrontal cortex in mk-801-treated balb/c mice.

Functional disorders of the glymphatic system and Aquaporin-4 (AQP-4) channels take part in the pathophysiology of neurodegenerative disease. The aim of this study was to describe the distribution of AQP-4 channels in the prefrontal cortex and hippocampus in a mouse model of NMDA receptor blocking agent-induced schizophrenia-like behavior model. NMDA receptor antagonist MK-801 was used to produce the experimental schizophrenia model.

Cervical Myelopathy Caused by Invaginated Laminae of the Axis into the Spinal Canal in a Pediatric Patient.

Cervical myelopathy caused by invaginated laminae of the axis is an extremely rare entity. Advanced imaging techniques are useful to define this rare pathology and site of the spinal canal compression. Surgical removal of the floating laminae is commonly an adequate treatment method.
