The aging process begins in the body after 25-30 years, when there are still no signs. But aging is not only wrinkles on the face and gray hair, and not even age-related ailments. One indicator of aging is a decrease in muscle mass.
What is sarcopenia
The fact that with age a person loses muscle mass, noted Hippocrates. But until recently, this fact was somehow not taken into account.

Muscle mass can also decrease due to other reasons: cancer, severe renal failure, AIDS, etc. But sarcopenia is precisely age-related changes. Continue reading
Rubella is an acute viral infectious disease. Her symptoms were first described by the German physician F. Hoffmann in 1740, but the causes of the disease became known only in the 20th century, when rubella virus was isolated and studied in 1961.

Hemoglobin is a component of red blood cell cells and is a protein containing iron. It is because of this component that our blood is colored red.
Each hemoglobin molecule contains four iron atoms. This iron has the property of easily binding to molecules of oxygen and carbon dioxide and just as easily give them. This determines the main function of hemoglobin – oxygen metabolism, namely: nutrition of the body with oxygen and removal of carbon dioxide from it. Continue reading
