Drug abusers are not completely abandoning prescription opioids for heroin, according to School of Medicine researchers. Instead, many use the two concurrently based on their availability. The researchers’ findings also reveal regional variations in the use of heroin and prescription painkillers.

Timothy Lohman, PhD, the Brennecke Professor of Molecular Biophysics at Washington University School of Medicine in St. Louis, was named a 2015 Biophysical Society Fellow.

A School of Medicine study may aid efforts to tailor smoking-cessation treatments to individual cigarette smokers. Researchers are recruiting 720 smokers whose DNA samples, from saliva, will be analyzed to identify genetic variations that influence smoking behavior, lung cancer risk and the effectiveness of smoking-cessation treatments.

Matthew A. Powell, MD, a noted gynecologic oncologist and researcher, has been named director of the Division of Gynecologic Oncology in the Department of Obstetrics and Gynecology at Washington University School of Medicine.

The retina’s rods and cones allow us to see. But although scientists have an idea of what makes rods perform and flourish, they’ve been somewhat in the dark regarding what keeps cones working and thriving. Now, School of Medicine researchers led by Thomas A. Ferguson, PhD, believe they’re closer to the answer and that their findings may one day help preserve vision in patients with age-related macular degeneration and other retinal diseases.

Larry J. Shapiro, MD, executive vice chancellor for medical affairs and dean of the School of Medicine, will host the annual Dean’s Update for all School of Medicine employees Nov. 12 and 13.

​​Timothy J. Ley, MD, a leukemia researcher and hematologist at the School of Medicine, has received a seven-year, $6.4 million Outstanding Investigator Award from the National Cancer Institute (NCI) of the National Institutes of Health (NIH). The funding will allow him to continue research aimed at understanding the mutations that initiate acute myeloid leukemia (AML), and how they might be targeted with new approaches.

Methadone — long used to treat pain and addiction — can be lethal if it lingers too long in the body. New research led by the School of Medicine’s Evan D. Kharasch, MD, PhD, has identified genetic subtypes in people that govern methadone clearance, findings that could help prevent some of the 5,000 methadone-related deaths that occur each year in the United States.

Craig A. Buchman, MD, a nationally recognized leader in otolaryngology and head and neck surgery, has been named head of the Department of Otolaryngology at the School of Medicine. He replaces Richard A. Chole, MD, PhD, who, after leading the department for 17 years, is stepping down to focus on research and patient care.

Studying mice with a variety of viral infections, scientists at the School of Medicine have demonstrated a way to dial up the body’s innate immune defenses while simultaneously attacking a protein that many viruses rely on to replicate. The findings reveal previously unknown weapons in the body’s antiviral immune arsenal and provide guidelines for designing drugs that could be effective against a broad range of viruses.
