Turning the heat up on tumors
Researchers find way to make tumor cells easier to destroy
May 6,
2008 -- Tumors have a unique vulnerability that can be exploited to make them more sensitive to heat and radiation, researchers at the School of Medicine report. The University radiation oncology researchers found that tumors have a built-in mechanism that protects them from heat (hyperthermia) damage and most likely decreases the benefit of hyperthermia and radiation as a combined therapy.

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.

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.
