| Blocking Toxic Effects Could Make Clot-buster Safer Posted: 26 Jan 2009 05:00 AM PST The drug tPA (tissue-type plasminogen activator) can break up the blood clots that cause strokes and heart attacks, but it can also loosen the blood-brain barrier and generate inflammation in the brain. In mice, genetically removing LRP1, a receptor for tPA, from brain cells called microglia can soften tPA's harmful effects. Blocking LRP1 could make tPA safer. |
| Posted: 26 Jan 2009 05:00 AM PST Studies on brain electrical signaling offer a fresh perspective on vertebrate evolution, provide additional evidence supporting Darwinian views of evolution, and may also lead to more effective treatment of epileptic seizures in infants. |
| Drug-coated Stents Less Risky For Heart Bypass Patients, Study Suggests Posted: 26 Jan 2009 05:00 AM PST Coronary bypass surgery may carry less risk of serious complications if stents coated with a drug that suppresses cell growth are used in the procedure rather than bare-metal stents, scientists have found. |
