Psychological interventions associated with breast cancer survivalA new study finds that patients with breast cancer who participate in intervention sessions focusing on improving mood, coping effectively, and altering health behaviors live longer than patients who do not receive such psychological support. Reported in the December 15, 2008 issue of CANCER, a peer-evaluated journal of the American Cancer Society, the study indicates that reducing the stress that can accompany cancer diagnosis and therapy can........Go to the Breast-cancer-blog (Added on 11/17/2008 10:16:12 PM)
How the brain takes care of thingsThanks to our ability to learn and to remember, we can perform tasks that other living things can not even dream of. However, we are only just beginning to get the gist of what really goes on in the brain when it learns or forgets something. What we do know is that changes in the contacts between nerve cells play an important role. But can these structural changes account for that well-known phenomenon that it is much easier to re-learn........Go to the Neurology news blog (Added on 11/14/2008 9:02:08 PM)
Mending broken hearts with tissue engineeringBroken hearts could one day be mended using a novel scaffold developed by MIT scientists and his colleagues.
The idea is that living heart cells or stem cells seeded onto such a scaffold would develop into a patch of cardiac tissue that could be used to treat congenital heart defects, or aid the recovery of tissue damaged by a heart attack. The biodegradable scaffold would be gradually absorbed into the body, leaving behind new tissue.
