Biomarkers for epithelial ovarian cancerWith the genomic revolution radical improvement has been made in methods of detection of ovary cancer. This is of the utmost importance, since the chances of successful therapy are strongly enhanced with early detection. In a special issue of Disease Markers, published by IOS Press, eleven articles explore new developments in the identification and understanding of biomarkers for epithelial ovary cancer.
A number of of these biomarkers may........Go to the Ovarian cancer blog (Added on 11/29/2007 10:51:45 PM)
New treatment for age-related macular degenerationWith 8 million people at high risk for advanced age-related macular degeneration, scientists from Harvard and Japan discovered that the experimental drug, endostatin, may be the cure. A research report reported in the December 2007 issue of The FASEB Journal, describes how giving endostatin to mice significantly reduced or eliminated abnormal blood vessel growth within the eye, which is ultimately why the disease causes blindness.
