removal of tumors. Lymphatic vessels normally remove fluid and proteins escaping from blood capillaries into surrounding tissues, and lymphedema is characterized by the disabling swelling of legs, and sometimes arms, that results when the lymphatic v...
Penn scientists identify novel pathway in aneurysms
..., with the only option of "watchful waiting" until surgical
repair is attempted, says Funk. Often, but not always, these types of aneurysms are associated with arteriosclerosis, a chronic inflammatory disease of the blood-vessel wall, consisting of fatty deposits that progress into major plaques that eventual...
Activated signaling pathway may predict lung cancer patients' response to gefitinib
...f patients with NSCLC are cured despite aggressive surgical
and chemotherapeutic intervention. Gefitinib, a cancer drug that interferes with the epidermal growth factor receptor (EGFR) pathway, is active in approximately 10% of NSCLC patients in whom standard therapy has failed. Although earlier studies have ...
Genetic discovery could dramatically reduce need for liver transplants in children

procedure is successful in many infants, three of every four children who have biliary atresia need a liver transplant before the age of 20. The total annual cost, including transplant care, of treating all infants with biliary atresia is estimated t...
New diagnostic technology helps justify earlier cataract surgery

procedures in people over 65 years of age in the United States. Last year, 2,775,000 procedures were performed in the U.S. (one procedure = one eye). A cataract is the clouding of the normally clear, natural crystalline lens of the eye. As cataract...

Research gives hope to preemies and Crohn's patients
