An alternative to chemotherapy

Nanoparticles tackle pediatric brain tumors (http://mednews.wustl.edu/tips/page/normal/11996.html)

An interdisciplinary team of researchers at Washington University in St. Louis, led by Karen L. Wooley, Ph.D., James S. McDonnell Distinguished University Professor in Arts & Sciences, is a step closer to delivering cancer-killing drugs to pediatric brain tumors, similar to the tumor that Senator Ted Kennedy is suffering from. Such tumors are often difficult to completely remove surgically; frequently, cancerous cells remain following surgery and the tumor returns. Chemotherapy, while effective at treating tumors, often harms healthy cells as well, leading to severe side effects especially in young children that are still developing their brain functions. In an effort to solve this problem, the Wooley lab has developed polymeric nanoparticles that can entrap doxorubicin, a drug commonly used in chemotherapy, and slowly release the drug over an extended time period.


National network of stroke centers reaches WUSM

Scientists Identify the Brain's Activity Hub
The New York Times and 1 others

July 1, 2008 -- The outer layer of the brain, the reasoning, planning and self-aware region known as the cerebral cortex, has a central clearinghouse of activity below the crown of the head that is widely connected to more-specialized regions in a large network similar to a subway map, scientists reported.
"This is just about the coolest paper I've seen in a long time, and forward-looking in terms of where the science is going," said WUSTL neurology and radiology professor Marcus Raichle, who was not involved in the research.


X-Rays, sunshine: Could radiation be hurting your health?
CNN.com/health

June 3, 2008 -- So how much radiation is too much? Scientists are still figuring that out-- and they tend to disagree about the risks. But they recently found worrying signs that radiation exposure is on the rise, thanks largely to the popularity of high-tech medical exams such as CT scans. WUSTL radiology professor Henry Royal comments on the benefits and risks of tests and treatments.


Dental work claim challenges antiquity of hobbit skeleton
Scientific American online

April 23, 2008 -- Most paleoanthropologists believe that the 18,000 year old Flores, Indonesia hobbit belongs to a new species of human, But now comes word that the specimen used to define the species appears to have had some dental work. If so, it would mean that the hobbit was just a modern human with a growth disorder, which is what critics have argued all along.
Paleoanthropologist and WUSTL radiology professor Charles Hildebolt examined the CT scans and said that it is unlikely that any type of filling material is in the tooth.


Experts Study Neuroscience Use in Courts
Associated Press and 82 others

March 3, 2008 -- Brain scans have emerged as potentially powerful tools in court battles over defendants' sanity. More defense attorneys are seeking scans showing brain damage or abnormalities that might have made it difficult for their clients to control violent impulses. Marcus E. Raichle, researcher of neurology and radiology at the School of Medicine, comments.


Clot-Busting Drug Offers New Approach to DVT
U.S. News & World Report online and 5 others

Jan. 29, 2008 -- When it comes to treating deep vein thrombosis, injecting the clot-busting drug alteplase (rTPA) directly into clots in the legs reduces the risk of complications and recurrence, a small U.S. study suggests. WUSTL radiology and surgery professor Suresh Vedantham thinks that this method of dissolving clots could eventually become an outpatient procedure.
