Heather Parrott and Jay Webb measure accelerations on a frozen field.This month, more than 130 million people will tune their televisions to football’s biggest event, the Super Bowl. It’s not certain which team will win, but it’s a good bet that someone may be injured. In fact, injuries are common to football at every level. In recent years, the sport has focused on playing fields as a significant source of injury, and new surfaces have been developed. But are the new surfaces safer? Emergency medicine researchers at the School of Medicine have found that in terms of concussion risk, the new fields are no safer, and they may get worse over time.

Sen. Jim Talent, Michael DeBaun and Isaac Singleton Jr. help raise awareness about sickle cell disease at a recent stamp dedication ceremony.In sickle cell disease, red blood cells change from their normal round shape to a curved, or sickle-shape. Sickle-shaped cells become stuck in blood vessels, causing damage to tissues and organs. WUSM pediatric hematologist Michael DeBaun says that ongoing blood transfusion therapy is vitally important for children with sickle cell disease, and treatment requires a sufficient supply of blood from African-American donors. “Black History Month is an ideal time to encourage African-Americans to come out and donate blood,” he says.

E. Coli (yellow) attaches to a host cell using sticky fibersNew insights into the bacteria responsible for urinary tract infections appear to open up an opportunity for disabling a wide range of infectious bacteria. Researchers at the School of Medicine recently revealed how a protein known as PapD helps E. coli assemble sticky fibers called pili that allow the bacterium to latch onto and infect host cells. Scientists are using what they’ve learned to begin designing pilicides, new treatments that stop pili formation and disrupt the infection process.

On the heels of President Bush’s call for medical liability reform during a recent visit to Collinsville, Ill., Washington University hosted a conference on the same topic, “Medical Malpractice and Tort Reform: Finding Truth and Common Ground.” Medical and legal experts gathered to discuss the hard road that must be paved toward a solution for this growing national concern. The consensus of the conference seemed to be that cooperation is the key.

Some instant teas may contain excess fluoride.Instant tea, one of the most popular drinks in the U. S., may be a source of harmful levels of fluoride, researchers at the School of Medicine report. The researchers found that some regular strength preparations contain as much as 6.5 parts per million (ppm) of fluoride, well over the 4 ppm maximum allowed in drinking water by the Environmental Protection Agency and 2.4 ppm permitted in bottled water and beverages by the Food and Drug Administration.

Brain cells in a mouse model of Alzheimer’s disease have surprised scientists with their ability to recuperate after the disorder’s characteristic brain plaques are removed.
