Better tissue healing with disappearing hydrogels

Posted: 06 Jun 2014 03:49 PM PDT

When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a research team makes use of a technique that keeps the stem cells in place, resulting in faster and better tissue regeneration.

Brain traffic jams that can disappear in 30 seconds

Motorists in Los Angeles, San Francisco and other gridlocked cities could learn something from the fruit fly. Scientists have found that cellular blockages, the molecular equivalent to traffic jams, in nerve cells of the insect's brain can form and dissolve in 30 seconds or less.

Vitamin D and the nursing mother

Posted: 06 Jun 2014 03:48 PM PDT

The not-often-discussed issue of Vitamin D deficiency in nursing mothers is discussed by an expert, and how it can affect the infants in their care. An "adequate" intake for nursing mothers is not the 400 IU/d the IOM recommends, but is instead in the range of 5,000-6,000 IU/d, taken daily. If they get that much, they will meet not only their own needs, but their infant's as well.

Research could lead to new cancer assay, aid both dogs and humans

Veterinary researchers have identified a unique group of proteins that indicate the presence of transitional cell carcinoma -- the most common cause of bladder cancer -- and may lead to a new assay which could better diagnose this disease in both dogs and humans. Bladder cancer is particularly common in some dog breeds, such as collies, sheepdogs and terriers, but is rarely diagnosed in animals before it has spread significantly. Some assays exist to detect it in humans, but they often have a high-number of false-positive identifications.
