Researchers at Washington University School of Medicine in St. Louis report they have developed an agent that protects cells from the lethal effects of radiation, regardless of whether it is given before or after exposure. Using this agent in mice, the investigators found that the treatment helped shield rapidly dividing cells that are most vulnerable to radiation-induced death, providing proof in principle that it is possible to fend off radiation damage.
Gravenhorst’s new ear is repositioned during an office visit to the maxillofacial prosthetics lab.Like any 17-year-old, Emily Gravenhorst follows a routine to get ready for a day of high school. She showers, styles her hair, puts on her make-up and eats breakfast. And just before she leaves the house, she puts on her right ear. That ear was created in the maxillofacial prosthetics laboratory at the School of Medicine, where one dental specialist and one technician help patients fit back into society after disfigurement due to accident or disease.
Joseph Culver, left, and Michael Welch examine a state-of-the-art diffuse optical tomography system, which allows researchers to visualize tumors without the use of radiation.Using a wide range of imaging techniques to visualize cancer in the body, radiology investigators at the Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine are expanding the boundaries of cancer detection, treatment and research. The strength of their efforts has received national recognition. For several years, Mallinckrodt Institute of Radiology at Washington University School of Medicine has ranked among the top three imaging programs in the United States in research grants received by the National Institutes of Health (NIH).

DXA scans of a male patient with osteoporosisAlthough women are four times more likely than men to develop osteoporosis, or porous bone, one in 12 men also suffer from the disease, which can lead to debilitating – or even life-threatening – fractures. In women, low estrogen levels after menopause have been considered an important risk factor for this disorder. Now research at Washington University School of Medicine in St. Louis has shown that low amounts of active estrogen metabolites also can increase the the risk of osteoporosis in men.
Using an innovative statistical approach, a research team from Washington University School of Medicine in St. Louis and the University of California, Los Angeles, has identified two regions of DNA linked to autism. They found the suspicious DNA with a much smaller sample of people than has been used traditionally in searches for autism genes.
Women with estrogen-responsive breast cancer are often prescribed a drug that reduces their estrogen levels. But because estrogen is important to bone health, there is widespread concern about how the estrogen-reducing drugs – called aromatase inhibitors – affect bones. A study at the School of Medicine will investigate bone loss in women taking aromatase inhibitors, and researchers are calling for interested women to volunteer.
Proclaiming that “energy and environmental issues represent the greatest challenges of this century,” Washington University Chancellor Mark S. Wrighton today joined presidents of six other premier research universities in calling for universities worldwide to marshal their resources for a global effort to secure a brighter, sustainable future. Plans for collaborative academic programs involving education, research, university operations, social sciences and policy studies are detailed in a statement issued May 7.
This year, determining when to arrive for the staff recognition ceremony and whether to go on a walk or play bingo at the 32nd annual Staff Day celebration May 21 is only a click away at staffday.wustl.edu.
Washington University Chancellor Mark S. Wrighton will announce a call to action for research universities worldwide to focus on the energy and environment as the greatest challenge of this century. The announcement, which comes as part of a conference involving the presidents of 12 premier research universities from Asia and the Middle East, will be made at noon May 7 in Whitaker Hall Auditorium, Washington University’s Danforth Campus.
