Using magnetism to turn drugs on and off
Many medical conditions, such as chronic pain, cancer and diabetes, require medications that cannot be taken orally, but must be dosed intermittently, on an as-needed basis, over a long period of time. A few delivery techniques have been developed, using an implanted heat source, an implanted electronic chip or other stimuli as an "on-off" switch to release the drugs into the body. But thus far, none of these methods can reliably do all that's needed: repeatedly turn dosing on and off, deliver consistent doses and adjust doses according to the patient's need.

Vaccine to prevent urinary tract infections shows early promise
University of Michigan (U-M) Scientists have made an important step toward what could become the first vaccine in the U.S. to prevent urinary tract infections, if the robust immunity achieved in mice can be reproduced in humans. The findings are published September 18 in the open-access journal PLoS Pathogens. more
