The activity of free radicals in the body for a long time It was considered a factor in the development of neoplastic processes and accelerate aging. However, recent years began to appear studies that refute the widespread notion about the dangers of free radicals, and the recent work of Canadian researchers also joined the This ranking. Biologists from McGill University have discovered that free radicals can "program" self-destruct damaged, cancer, and and cells infected by viruses.
The researchers argue that the increase in the level of free radicals in the body does not necessarily mean that it is decrepit and It becomes vulnerable to disease - on the contrary, it can give a strong positive effect. During experiments with nematode worms, the researchers were able to achieve significant prolongation of life after increased generation of free radical production in the test organisms.
Science is well known for the harm that can cause free radicals (oxidants) as a result of pathology, particularly when they start affect the cells of the body, giving a signal to decomposition. Canadian researchers have found that cell death - apoptosis, "programmed" and injured cells. Thus, free radicals cause the self-destruct cancer and virus-infected cells.
The discovery of this mechanism can provide new tools to combat cancer and other dangerous diseases developing due to the weakening defenses with age. At the same time the need arises revision approved by the use of antioxidant substances, used in the form of biologically active additives. These substances inhibit free radicals - perhaps the body will only harm.
It is significant that earlier British scientists have proved the benefit free radicals for the heart. (READ MORE)
the damage of free radicals
The researchers found that the mechanism of self-destruction, triggered cells in patients under the influence of free radicals and strengthens the body's defenses and contributes to the extension of a fulfilling life. Thus, it is impossible evaluate the effects of free radicals, highly negative, experts believe Canada.
"People think that free radicals cause damage aging, but in fact it is not "- summed up the results of the research of his head Professor Siegfried Hekimi in the scientific journal Cell.
According to experts, although production of free radicals in the body increases with age, it is not the reason Aging because increasing their level is a logical response organism for increasing the amount of damage to it.
