Otzi Iceman had genetic predisposition for atherosclerosis: Much the same in ancient peoples as it is today
While prevalence and types of risk factors for atherosclerosis have varied over time from ancient times to modern society -- such as levels of obesity, physical activity -- genetic predisposition/risk for the condition today appears to be very similar to that in ancient times.
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
Patients were interviewed by a research team in great detail about the symptoms they experience weeks, months or even years after an acute diverticulitis attack. 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. The researchers used those insights to develop a questionnaire to help doctors better assess the long-term impact of diverticulitis, which ultimately could lead to better understanding and management of the disease.
