A group of researchers at Tel Aviv University and the Shamir Medical Center have found during clinical trials they conducted in healthy aging adults a unique mechanism that allows them to halt aging in blood cells. During the course of the clinical trials, patients were given hyperbaric oxygen treatment (HBOT) - most associated with those suffering from air embolism - in which a highly pressurized form of oxygen is given to patients in an air chamber, and speeds up the flow of oxygen to injured tissues or blood cells. In this case, HBOT was given to healthy older patients and was seen to seemingly reverse biological processes of aging, namely causing the lengthening of the telomeres, or parts of the chromosome that shrink as an individual ages. The study also found that there was a decrease in the build up of old and faulty cells, or senescent cells, in those patients’ blood streams. After examining the patients’ DNA and blood, researchers found a 20%-38% lengthening in the telomeres and a 11%-37% decrease of senescent cells. During the course of the study, patients aged 64 and over were given 60 HBOT sessions over the course of three months, providing blood samples several times during the course of the experiment.
