High Expression of GABA Receptor β Subunit Genes Is Associated with Longer Overall Survival in Medulloblastoma.

Most of the rapid inhibitory neurotransmission in the brain is mediated through activation of the γ-aminobutyric acid (GABA) type A (GABA) receptor, which is a ligand-gated ion channel. GABA receptor activation via GABA binding allows for an intracellular influx of Cl ions, thus inducing cellular hyperpolarization. Each GABA receptor consists of a combination of five subunits, and several subunits have been proposed as biomarkers and therapeutic targets in cancer.

Identification of CD114 Membrane Receptors as a Molecular Target in Medulloblastomas.

Medulloblastomas are the most common solid tumors in children, accounting for 8-30% of pediatric brain cancers. It is a high-grade tumor with aggressive behavior and a typically b poor prognosis. Its treatment includes surgery, chemotherapy, and radiotherapy, and presents high morbidity.

[Surgical approaches to petroclival meningiomas Part 2: narrative review of what we learned with 30 cases].

Background: The surgical ressection of petroclival meningiomas is challenging due to its deep location and relationship with vital neurovascular structures. Usually they are benign injuries, but they can involve or infiltrate skull base bones, dura mater and brainstem. This makes the total removing very difficult or impossible without causing neurological deficits.

Avoiding vascular complications in insular glioma surgery - A microsurgical anatomy study and critical reflections regarding intraoperative findings.

Introduction: Vascular lesions in insular glioma surgery can severely impact patients' quality of life. This study aims to present the results of our dissections and authors' reflections on the insular vascular anatomy.

Matherials And Methods: The insular vascularization was examined using ×3 to ×40 magnification in 20 cadaveric cerebral hemispheres in which the arteries and veins had been perfused with colored silicone.
