Researchers from the United States have found hundreds of substances in human blood, the concentration of which canchange from
Scientists decided to find out whether it is possible to track the general trend of aging in terms of blood composition for all people.Researchers at Stanford University studied a group of subjects, some of whom were healthy and some of whom had prediabetes.Over the course of four years, these people took blood tests, and the scientists looked for biomarkers associated with age-related changes in a person.
At first, the researchers found 184 such biological markers, but it turned out that the concentrations of certain substances did not change in the same way in people.Some patterns were found when comparing healthy people with patients with prediabetes, but they did not describe the full picture.
As a result, scientists decided that the aging trajectory ofpeople is determined largely by internal factors. Then they collected 608 markers and divided them into four groups depending on the physiological processes with which they are associated: immunity, metabolism, impaired kidney and liver.
Each subject was visible with agechanges in at least one of these marker groups. Why divide people by type of aging? So that in the future it is better to predict a deterioration in their health or to select treatment for old age.
