It can be said that aging is a process of not returning, but US researchers have shown that at least some aspects of this situation can be reversed.
In the new report published in Cell, experts from Harvard University (USA) used a chemical to rejuvenate muscle in experimental mice. The results show that this process is equivalent to converting muscle mass in 60-year-olds back to a 20-year-old state, but muscle strength has not yet improved.

To do this, experts have discovered an entirely new mechanism of aging, and so reverses the entire process. Specifically, they focus on a chemical called NAD . The observed results show that the content of this substance naturally decreases in all cells when the object ages with time. Along with the gradual disappearance of NAD, the function of mitochondria, the cell's internal energy machine, also stalled, leading to reduced productivity and aging cells.
Experimental results show an effort to increase NAD levels in cells , by adding chemicals that naturally convert NAD, which can reverse cell destruction over time. Accordingly, a week of supplementation of 'rejuvenation drugs' for 2-year-old mice can help their muscles return to active status as at 6 months of age in terms of mitochondrial function, eliminate toxic waste in the muscle, prevent inflammation and insulin resistance. Dr. Ana Gomes of Harvard University confidently said it would soon find a way to restore muscle strength if the treatment is prolonged.
Currently, the team continues to study, with a phase of clinical trials scheduled for 2015. However, this approach is not yet the optimal treatment for the entire aging process. NAD is just one aspect of a big problem, while other factors that contribute to cell aging remain unresolved, such as the telomere's shortened condition (the end of the chromosome). or damage to DNA, which cannot be reversed. However, the scientific community highly appreciated the results of the study, and argued that it is necessary to learn more about the mechanisms before the preparation of drugs to partially eliminate the effect of time on the organism.
