Ultrasound: restoring dopaminergic pathway at Parkinson's

11.06.2019

While there are several thousand drugs available to treat brain diseases, they cannot penetrate the blood-brain barrier (BBB) into the brain. The BBB, which protects the brain from pathogens, also prevents most drugs from gaining access to the brain functional tissue, a well-known challenge to the treatment of all brain diseases including neurodegenerative disorders like Parkinson's disease.

Photochemical internalization – A new hope against bile duct cancer?

03.07.2017

Advanced bile duct tumors cannot always be removed surgically. Then, patients receive chemotherapy and a stent that corrects the narrowing of the bile duct that is caused by the tumor. Another, local therapy option is tested at the University Hospital Frankfurt: laser light is used to transport drugs into the tumor during photochemical internalization.
