Nanoparticle Enhanced Radiotherapy (NERT) for Brain Tumor Treatment (2024 Research)

Nanoparticle-enhanced radiotherapy (NERT) is a promising approach to improving brain tumor treatment by enhancing radiotherapy efficacy through targeted delivery and radiosensitization while overcoming challenges posed by the blood-brain barrier. Highlights: Mechanisms of Action: NERT utilizes nanoparticles (NPs) as radiosensitizers, enhancing radiation-induced damage through physical dose enhancement and biological/chemical sensitization. Types of Nanoparticles: Various NP types, …

OCD Treatment with Antidepressants (SSRIs) Alters Brain Structure & Functions (2024 Study)

Antidepressant treatment in OCD is linked to structural and functional brain changes, particularly in corticosubcortical areas, but these findings need further validation in larger, more homogeneous samples. Highlights: Antidepressant Use: Antidepressants, especially SSRIs, are a primary treatment for OCD, resulting in significant brain changes. Brain Structure Changes: Studies show volume alterations in the thalamus, amygdala, …

Repurposing Antipsychotics & Antidepressants to Treat Glioblastoma (2024 Study)

Repurposing antipsychotics and antidepressants with favorable safety profiles and blood-brain barrier permeability shows promise for glioblastoma (GBM) treatment, primarily through disrupting lysosomal function and inducing cell death. Highlights: Mechanism of Action: The studied antipsychotics and antidepressants induce GBM cell death by disrupting lysosomal function, leading to lysosomal membrane rupture. PTEN Sensitivity: GBMs with intact PTEN …
