Purpose: Malignant cerebral tumors have poor prognosis and the blood-brain barrier is a major hindrance for most drugs to reach those tumors. Lipid nanoparticles (LDE) that bind to lipoprotein receptors may carry anticancer drugs and penetrate the cells through those receptors that are overexpressed in gliomas. The aim was to investigate the in vivo uptake of LDE by human cerebral tumors.

Lipid-based nanoparticle systems have been used as vehicles for chemotherapeutic agents in experimental cancer treatments. Those systems have generally been credited with attenuating the severe toxicity of chemotherapeutic agents. This study aimed to investigate the effects of associating paclitaxel (PTX) with a lipid-based nanoparticle system on a nonhuman primate, , documenting the toxicity as measured by serum biochemistry, which is a detailed analysis of blood and tissue.

Despite the remarkable progress in the characterization of the molecular pathogenesis of glioblastoma multiforme (GBM), these tumors remain incurable and, in most cases, refractory to aggressive cytotoxic treatments. We conducted a morphological and cytogenetic study in two GBM cell lines (U343 and AHOL1), before and after treatment with pisosterol (at 0.5, 1.

Objective: Searching usefulness of computed tomography with three dimensional reconstruction in planning accurate cranial approaches to treat subcortical lesions.

Method: Eight patients with neoplastic subcortical convexity-based lesions were surgically treated following spatial coordination obtained with three dimensional computed tomography reconstruction (CT 3D).

Results: Accurate approaches were accomplished, allowing a safe and optimized removal of neoplasms in all cases.
