Bear Cub grants awarded

Washington University in St. Louis has awarded five Bear Cub fund grants totaling $190,000 to support innovative research that has shown commercial potential. Jerry Morrissey (right), PhD, received one of the grants to develop rapid tests for the early development of kidney cancer.

New nanoparticles make blood clots visible

For almost two decades, cardiologists have searched for ways to see dangerous blood clots before they cause heart attacks. Now, researchers at Washington University School of Medicine in St. Louis report that they have designed nanoparticles that find clots and make them visible to a new kind of X-ray technology.

Committee recommends changes in cardiovascular disability benefits

A Washington University scientist has been working with the federal government to determine what makes heart disease disabling. To determine cardiac disability, the committee recommended more functional testing and also discussed the need to evaluate not only a patient’s heart but the patient’s mood as well because depression can make heart disease worse. 

Inhibiting fatty acids in immune cells decreases atherosclerosis risk

Scientists at Washington University School of Medicine in St. Louis have found a way to significantly reduce atherosclerosis in mice that does not involve lowering cholesterol levels or eliminating other obesity-related problems. Atherosclerosis is the process through which fatty substances, such as cholesterol and cellular waste products accumulate in the lining of arteries. The research team inhibited atherosclerosis in the mice by interfering with production of a substance called fatty acid synthase, an enzyme that converts dietary sugars into fatty acids in the liver.  

Let the NO flow: discovery provides key to improving blood circulation, healing

An angiogram, or X-ray image of blood vesselsScientists have uncovered a new biomedical technique that could increase blood flow to alleviate problems associated with cardiovascular disease, diabetes and many surgical procedures. They found that blocking the action of a blood-clot-associated protein turns up the effect of a biologically produced gas that can open blood vessels and increase blood flow.

Drug can quickly mobilize an army of cells to repair injury

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 the School of Medicine demonstrated that a drug called AMD3100 can mobilize angiogenic cells from bone marrow of human patients in a matter of hours.
