    Celiac Research Update

    Celiac disease is an uncontrolled immune response to wheat gluten and similar proteins of rye and barley. In those who have celiac disease, gluten can damage the small intestine, inhibit nutritional uptake and lead to malnutrition. Because celiac disease has a genetic component, there can be a much higher prevalence of the disease within families. Dutch researchers, led by Frits Koning of the Leiden University Medical Center, published a study on an enzyme that showed promise as a treatment for celiac disease. The enzyme, prolyl endoprotease, or PEP, could quickly break down gluten in the stomach before it ever reached the small intestine, where it causes damage. Dr. Koning updates us. (Begins at 02:45)

    Nanoparticles and Disease

    Nanoparticles, 1,000 times smaller than a bacterium, are being manufactured and incorporated into some commercial products such as cosmetics and clothing. While nanotechnology holds promise, there is little understanding of how these super small particles might affect us if they get inside our bodies. Researchers from the Mayo Clinic College of Medicine discuss their research into the role the particles might play in disease.
