A new imaging method successfully identifies miniscule, young blood vessels that form during the development of plaques, according to a study in rabbits led by Washington University School of Medicine in St. Louis. These plaques are akin to atherosclerosis in humans, the primary cause of heart attack and stroke.
"Weve developed a way to take non-invasive images of very early plaques, before theyre detectable by any other means," says Samuel A. Wickline, M.D., professor of medicine and biomedical engineering and one of the studys senior authors. "This same technology, we think, will allow us to detect very early cancers and other inflammatory events as well."
Patrick M. Winter, Ph.D., research instructor of medicine and first author of the study, presented the teams results Nov. 19 during the Russell Ross Memorial Lecture and New Frontiers in Atherosclerosis at the American Heart Associations Scientific Sessions 2002 in Chicago. Gregory M. Lanza, M.D., Ph.D., assistant professor of medicine and biomedical engineering, is co-senior author.

Combining an atomically thin graphene and a boron nitride layer at a slightly rotated angle changes their electrical properties. Physicists at the University of Basel have now shown for the first time the combination with a third layer can result in new material properties also in a three-layer sandwich of carbon and boron nitride. This significantly increases the number of potential synthetic materials, report the researchers in the scientific journal Nano Letters.
Last year, researchers in the US caused a big stir when they showed that rotating two stacked graphene layers by a “magical” angle of 1.1 degrees turns...
