Postdoctoral researchers will showcase their work at the 8th Annual Postdoc Scientific Symposium at Washington University School of Medicine in St. Louis. The symposium will be held from 11:30 a.m.-5:30 p.m., March 29, 2012, at the Farrell Learning and Teaching Center Atrium and Connor Auditorium.

Batten disease is a rare but fatal neurological disorder that typically strikes young children. Working in mice with the infantile form of the disease, scientists have discovered dramatic improvements in life span and motor function by treating the animals with gene therapy and bone marrow transplantation.

By mapping the evolution of cancer cells in patients with myelodysplastic syndromes who later died of leukemia, Timothy Graubert, Matthew Walter and their Washington University colleagues have found clues to suggest that targeted cancer drugs should be aimed at mutations that develop early in the disease.

With every meal, immune cells in the intestine stand like sentries at a citadel, turning away harmful bacteria but allowing vitamins and nutrients to pass. Now, researchers at Washington University School of Medicine in St. Louis have identified the cells that chaperone food antigens, or proteins, in the intestine so that the immune system doesn’t mount an attack. Their discovery provides scientists with a potential target for therapies against inflammatory bowel disease, celiac disease and food allergies.

Louis W. Sullivan, MD, secretary of the Department of Health and Human Services in the administration of President George H. W. Bush and president emeritus of the Morehouse School of Medicine, will lead a public forum on the future of health care at 4 p.m. Wednesday, April 11, at the Eric P. Newman Education Center, 320 S. Euclid Ave., at Washington University School of Medicine in St. Louis.

Researchers, including Richard Wilson, PhD, director of The Genome Institute, have identified the first gene mutation associated with a chronic and often fatal form of neuroblastoma that typically strikes adolescents and young adults. The finding provides the first clue about the genetic basis of the long-recognized but poorly understood link between treatment outcome and age at diagnosis.

A program that helps obese patients improve healthy behaviors is associated with modest weight loss and improved blood pressure control in a high-risk, low-income group, according to Graham A. Colditz, MD, DrPH, at Washington University School of Medicine. Compared to those receiving usual care, the lifestyle intervention slowed increases in weight and blood pressure in this population of high-risk patients.

Doctors at Washington University School of Medicine in St. Louis, working with Shriners Hospital for Children and other institutions, have identified a promising new treatment for a rare and sometimes life-threatening bone disorder that can affect infants and young children. Known as hypophosphatasia, the condition upsets bone metabolism, blocking important minerals such as calcium from depositing in the skeleton.

Emergency physician Chris Carpenter, MD, is conducting a study of patients in the emergency room who are older than 65 and at increased risk of having dementia. He wants to determine if referring suspected Alzheimer’s patients to an outreach agency will reduce frequent returns to the emergency department and help them remain independent longer.

Students in the Program in Occupational Therapy talk with Liz Hanson of MarianJoy at the Occupational Therapy/Physical Therapy Job Fair Feb. 23 at the School of Medicine. More than 200 students from Washington University and eight other schools attended the fair, which featured more than 50 representatives from employers in the two fields.
