Less nutritious food contributes to a better functioning of the brainLess nutritious food contributes to a better functioning of the brain Less nutritious food contributes to a better functioning of the brain, according to U.S. scientists. Researchers from the University of Florida found that caloric restriction reduces the rate of accumulation in the brain of Wistar rats proteins associated with loss of nerve cells. It was found that the level of protein that protects the nerve cells from death, two times higher in the brain of rats treated with 40% less nutritious diet than the control group. The obtained results help to understand the mechanism not only of normal aging, with its weakening such nervous functions, such as memory and intelligence, but also diseases associated with the loss of excessive amounts of nerve cells (Alzheimer's and Parkinson's). Aging is a complex process, the older the body, especially cells of the nervous system is prone to apoptosis is a genetically programmed cell death. Читать полностью -->

The effect of massage on the circulatory and lymphatic systems

The effect of massage on the circulatory and lymphatic systemsThe main function of the circulatory system is to ensure the exchange of substances between the tissue and the external environment: the oxygen supply of energy and nutrients and removal of metabolic products. The circulatory system consists of big and small circles of blood circulation. In the big circle of blood circulation arterial blood from the left ventricle enters the aorta, arteries, arterioles, capillaries, venules, veins. In the pulmonary circulation of the venous blood from the right ventricle enters the pulmonary artery, arterioles and capillaries of the lungs where it is oxygenated and pulmonary veins flows into the left atrium. Muscles are Contracting, result in the movement of venous blood. The veins are special valves that provide translational movement of blood to the heart and prevent the reverse current.
