Anti-inflammatory effects of active Vitamin D hormone on extracranial vessels after subarachnoid hemorrhage in a murine model

Abstract Subarachnoid hemorrhage (SAH) causes systemic inflammation and endothelial dysfunction, contributing to cerebral vasospasm and poor outcomes. While Vitamin D hormone (1,25-dihydroxy cholecalciferol, calcitriol, 1,25-VitD) has known vasoprotective and anti-inflammatory ef...

Frameless VarioGuide biopsy for pediatric brainstem lesions in the molecular era: diagnostic performance and workflow characteristics in a comparative single-center series

Abstract Background Molecular characterization has become essential for the diagnosis and treatment of pediatric brainstem lesions. While frame-based stereotactic and robotic-assisted biopsies are well established, comparative data on frameless VarioGuide biopsy for pediatric bra...
