Ethnic differences found for fatty liver disease and insulin resistance

A new study suggests that the metabolic response to obesity and insulin resistance, particularly as it pertains to the liver, differs among ethnic groups in the U.S. African-Americans are more resistant to the buildup of fat in the abdominal adipose tissue and liver, and to high triglyceride levels associated with insulin resistance.

Life-giving technology: Camera pills and ultrasound creating maps of the body

For more than ten years, senior medical officer Ronald Marvik at St. Olav's Hospital in Trondheim has been collaborating with SINTEF scientist Thomas Lango. Together, they have created a new IT-base window on the inside of the body, a window that makes a patient transparent on a screen when a surgeon inserts operating instruments through small openings in the abdominal wall.

Scientists identify human monoclonal antibodies effective against bird flu

Researchers at the Dana-Farber Cancer Institute (Dana-Farber), Burnham Institute for Medical Research (Burnham) and the Centers for Disease Control and Prevention (CDC) have reported the identification of human monoclonal antibodies (mAb) that neutralize an unprecedented range of influenza A viruses, including avian influenza A (H5N1) virus, previous pandemic influenza viruses, and some seasonal influenza viruses.
