Building a new approach to medicine

Designed to bring together great scientific minds in a comfortable, productive atmosphere, the Farrell Learning and Teaching Center became the new focal point at the School of Medicine in August. Read more about the $35 million state-of-the-art facility in the following St. Louis Post-Dispatch article.

Biomedical engineers at Washington University in St. Louis have now identified how people use individual experiences to improve performance.

Researchers find mutiple proteins that stick to medical devices

Donald Elbert, Ph.D., Washington University assistant professor of biomedical engineering, used advanced protein separations and mass spectrometry to track the proteins on the surfaces of various polymers used in medical devices. The analysis techniques, collectively called ‘proteomics,’ are most often used to study protein expression in cells.

Female athletes at risk for gender-related injuries

Women have different sports medicine needs than men.In sports medicine, it isn’t always true that what’s “good for the goose is good for the gander.” Reporting on issues unique to female runners in the journal Physical Medicine and Rehabilitation Clinics of North America, Washington University physical medicine and rehabilitation specialists say women’s bodies adapt to athletic challenges differently. They say that when female athletes get injured, health-care professionals need to consider the anatomic, biomechanical, hormonal and functional factors that are unique to women.

Cell phone radiation doesn’t cause cellular stress, doesn’t promote cancer

Cell phone radiation doesn’t stress human cells.Weighing in on the debate about whether cell phones have adverse health effects, researchers at Washington University School of Medicine in St. Louis have found that the electromagnetic radiation produced by cell phones does not activate the stress response in mouse, hamster or human cells growing in cultures. The stress response is a cellular protection mechanism set into motion by various adverse stimuli, including heat shock, heavy metals, and inflammation. High levels of the stress response in cells are thought to result in changes associated with malignancy.
