Nanotechnology enables low-dose treatment of atherosclerotic plaques

These before (left) and after images show the effects of fumagillin-laden nanoparticles in a rabbit aorta.In laboratory tests, one very low dose of a drug was enough to show an effect on notoriously tenacious artery-clogging plaques. But it wasn’t so much the drug itself as how it was delivered. Fumagillin — a drug that can inhibit the growth of new blood vessels that feed atherosclerotic plaques — was sent directly to the base of plaques by microscopically small spheres called nanoparticles.

Medical steroid’s baffling connection to osteoporosis becomes clearer

Dark areas (marked with arrows) in the first image show a process of bone renewal and strengthening. The second image shows a reduction in this process after a cortisone injection.Scientists are closing in on the solution to a persistent medical puzzle: why do high doses of cortisone, widely prescribed for asthma, rheumatoid arthritis and other inflammatory and autoimmune conditions, weaken bones? Researchers at the School of Medicine have identified osteoclasts, cells that dismantle old bone, as the essential link between osteoporosis and cortisone.

Washington University physicians embrace e-records

Computer screens are replacing X-rays and paper files.Surgeons and staff no longer wonder where’s the chart in the Division of Cardiothoracic Surgery at Washington University School of Medicine. That’s because the division switched from using paper files to a fully electronic medical record system. Electronic records are thought to improve the quality of care, reduce errors and improve efficiency. The federal government has set a goal for widespread adoption of e-records in medical practices within the next 10 years.
