New procedure shows promise for treating brain tumors
Los Angeles Times

Patients with brain tumors don’t have many good options — surgery and radiation can damage crucial parts of the brain, and chemotherapy drugs don’t easily cross the blood-brain barrier. A new procedure using magnets, ultrasound and minuscule drug-coated particles may be an effective solution, according to a study on rats published in Tuesday’s edition of the journal Proceedings of the National Academy of Sciences.

The researchers, led by Dr. Kuo-Chen Wei of Chang Gung University in Taiwan, injected tiny magnetic beads called nanoparticles, coated with a chemotherapy drug, into the rats’ tails.
