An approach proven to cure a rat model of type 1 or juvenile-onset diabetes also works in a rat model of type 2 or adult-onset diabetes, according to a new report from researchers at the School of Medicine.

A long-term study of the elderly has revealed that their average rate of weight loss doubles in the year before symptoms of Alzheimer’s-type dementia first become detectable. The finding may be useful to researchers seeking ways to detect and treat Alzheimer’s before it causes irreversible brain damage.

Some Washington University orthopaedic surgery patients will soon be treated at a new $13 million outpatient facility in Chesterfield, Mo.

School of Medicine researchers are investigating why high-dose cortisone is the second most common cause of osteoporosis.

The Department of Biochemistry and Molecular Biophysics celebrates the contributions of former department head and longtime professor Carl Frieden, Ph.D.

Olga Pontes is Going FISHin’.Biologists at Washington University in St. Louis have made an important breakthrough in understanding a pathway plant cells take to silence unwanted or extra genes using short bits of RNA. Basically, they have made it possible to see where, and how, the events in the pathway unfold within the cell, and seeing is believing, as the old saying goes. Craig Pikaard, Ph.D., Washington University professor of biology in Arts & Sciences and his collaborators have described the roles that eight proteins in Arabidopsis plants play in a pathway that brings about DNA methylation, an epigenetic function that involves a chemical modification of cytosine, one of the four chemical subunits of DNA.

Neurosurgeons at St. Louis Children’s Hospital and Washington University School of Medicine in St. Louis are renewing calls for a ban on use of all-terrain vehicles (ATVs) by children under age 16 after a 10-year review of injuries caused by the vehicles.

But to date about two-dozen people around the world have received hand transplants. Thomas Tung, M.D., conducts research within this relatively unorthodox realm of surgery, investigating the use of therapy that could potentially allow the body to accept donor tissue without the use of immunosuppressive medication.

Red areas of the circled leg in the right image show increased blood flow due to angiogenic cells.To speed healing at sites of injury – such as heart muscle after a heart attack or brain tissue after a stroke – doctors would like to be able to hasten the formation of new blood vessels. One promising approach is to “mobilize” patients’ blood vessel-forming cells, called angiogenic cells, so these cells can reach the injured area. Recently, researchers at Washington University School of Medicine in St. Louis demonstrated that a drug called AMD3100 can mobilize angiogenic cells from bone marrow of human patients in a matter of hours.
