New research delimits the possible causes of celiac disease


The amount of gluten could be a more important clue than breast-feeding or the timing of the introduction of gluten for continued research into the causes of celiac disease (gluten intolerance). This is one of the findings from several extensive studies of children with an increased genetic risk of celiac disease conducted by researchers at Lund University in Sweden.

Response to house dust mites is age-dependent


In adults with a house dust mite allergy, a cascade of inflammatory signals on the surface of the airways leads to airway remodeling. This process cannot be influenced by standard cortisone therapy. Researchers at Helmholtz Zentrum München and the Technical University of Munich have reported these findings.

Brains of overweight people "ten years older" than lean counterparts at middle-age


From middle-age, the brains of obese individuals display differences in white matter similar to those in lean individuals ten years their senior, according to new research led by the University of Cambridge. White matter is the tissue that connects areas of the brain and allows for information to be communicated between regions.

Embryonic gene Nanog reverses aging in adult stem cells


The fountain of youth may reside in an embryonic stem cell gene named Nanog. In a series of experiments at the University at Buffalo, the gene kicked into action dormant cellular processes that are key to preventing weak bones, clogged arteries and other telltale signs of growing old.
