Software enhancement of breast MRI scans help radiologists reduce false positives

Using commercially available software to enhance breast scans done by magnetic resonance imaging (MRI) reduces the number of false positive identifications of malignant tumors and the subsequent need for biopsies, according to a new study. more  

Chronic constipation study offers relief to all sufferers

A clinical trial including 50 medical centers and 304 patients has confirmed that polyethylene (PEG) laxative is safe for patients suffering from chronic constipation. The study, published in The American Journal of Gastroenterology, indicates that even elderly patients can use the drug safely for up to six months. more

Penn study maps road to cure for inherited eye diseases

Researchers at the University of Pennsylvania School of Medicine have identified proteins in the rod and cones of the eye that could lead to the discovery of the genetic causes of a host of inherited eye diseases. The investigators hope to gain a clearer understanding of what goes wrong at the most basic level in these diseases that cause blindness and other disorders. more

On target; Multifunctional nanoparticle platforms for targeting and imaging cancer cells  

There has been much recent interest in how nanotechnology will impact the field of medicine. Unfortunately, a number of promising nanostructured systems have turned out to be extremely toxic to humans, thus precluding their use in clinical applications and dashing hopes of an early success for the interdisciplinary field of nanobiotechnology. Now a group of researchers at the University of Michigan Nanotechnology Institute for Medicine and Biological Sciences have devised a multifunctional nanoparticle platform comprising nanoparticles synthesized within dendrimers equipped with targeting molecules and dyes. These dendrimer nanoparticle systems are able to seek out and specifically bind to cancer cells. more

Stem cells to repair damaged heart muscle; First ever-surgical trial gets the go-ahead 

In the first trial of its kind in the world, 60 patients who have recently suffered a major heart attack will be injected with selected stem cells from their own bone marrow during routine coronary bypass surgery. more
