  • Mechanism promoting multiple DNA mutations described by scientists
    Recent studies have shown that cancer development frequently involves the formation of multiple mutations that arise simultaneously and in close proximity to each other. These groups of clustered mutations are frequently found in regions where chromosomal rearrangements take place. The finding that cancer development often involves multiple mutations arising in clusters and in regions where chromosomal rearrangement takes place may one day lead to new cancer therapies.

  • Diverticulitis patients reveal psychological, physical symptoms long after acute attacks

Their striking findings add to growing evidence that, for some patients, diverticulitis goes beyond isolated attacks and can lead to a chronic condition that mimics irritable bowel syndrome.
