Gene That Regulates Adult Stem Cell Growth

Gene That Regulates Adult Stem Cell Growth
A new discovery in stem cell research may mean big things for cancer patients in the future. Gary Van Zant, Ph.D., and a research team at the University of Kentucky published their findings today in Nature Genetics, an international scientific journal.

The scientists genetically mapped a stem cell gene and its protein product, Laxetin, and building on that effort, carried the investigation all the way through to the identification of the........Go to the Research news blog (Added on 1/15/2007 5:04:19 AM)

High-Power MRI in Unusual Tumor Cases

High-Power MRI in Unusual Tumor Cases
A Mayo Clinic surgical team has observed that using a 3-Tesla MRI in surgical decision making provides a new level of capability to predict surgical outcomes that improves patient care by minimizing the potential for unsuccessful tumor-removal surgeries. The Mayo Clinic report appears in the recent issue of the Journal of Neurosurgery www.thejns-net.org/jns/issues/current/toc.html.

Novel Radiation Technique To Treat Liver Cancer

Novel Radiation Technique To Treat Liver Cancer
Physicians at Mayo Clinic are now using tiny glass bubbles filled with radioactive material to deliver high doses of tumor-killing radiation directly to liver tumors. They say the procedure is better tolerated than other forms of intra-arterial liver cancer therapys, and may be the best option for some patients who aren't candidates for other therapys, including surgery or liver transplantation.

The technique, called either radioembolization........Go to the Cancer-blog (Added on 1/12/2007 4:43:32 AM)

MR imaging can make a dramatic difference in the management of patients with ankle pain, changing therapy in about one-third of the patients, a new study finds.

The study, of 91 patients, observed that MR changed the management plans of 35% of patients, said Philip W.P. Bearcroft, MD, of Cambridge University Hospitals in England.
