Cancer cells' DNA repair disrupted to increase radiation sensitivity

ScienceDaily (Dec. 1, 2011) — Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells' sensitivity to radiation treatment and kills them more quickly, according to a study in Cancer Prevention Research.Researchers would to like see their laboratory findings -- published in the journal's Dec. 5 print edition -- lead to safer, more effective combination therapies for hard-to-treat pediatric brain cancers like medulloblastoma and high-grade...

Less invasive anesthetic methods better for endovascular aneurysm repair

ScienceDaily (Oct. 27, 2011) — Researchers have identified a safer, more cost effective way to provide anesthesia for patients undergoing endovascular repair of an abdominal aortic aneurysm -- a common, often asymptomatic condition that, if not found and treated, can be deadly.A new study done by investigators at Wake Forest Baptist Medical Center found that using less invasive spinal, epidural and local/monitored anesthesia care (MAC) is better than general anesthesia for elective endovascular...
