Effects of stress on memory from the adrenal gland. These substances are the main factors responsible for the stress response in humans. Cortisol for example stimulates the mobilization of free fatty acids and proteins and the breakdown of amino acids, and increases serum glucose level and blood pressure, among other effects. On the other hand, aldosterone is responsible for water retention associated with stress. As a result of cells retaining sodium and eliminating potassium, water is retained and blood pressure is increased by increasing the blood volume. A second physiological response in relation to stress occurs via the vasopressin axis. Vasopressin, also known as antidiuretic
Mucus improve the odds of pregnancy. It is also proposed as a method to avoid pregnancy. Mucus is able to absorb water or dehydrate through pH variations. The swelling capacity of mucus stems from the bottlebrush structure of mucin within which hydrophilic segments provide a large surface area for water absorption. Moreover, the tunability of swelling effect is controlled by polyelectrolyte effect. Polymers with charged molecules are called polyelectrolytes. Mucins, a kind of polyelectrolyte proteoglycans, are the main component of mucus, which provides the polyelectrolyte effect in mucus. The process of inducing this effect comprises two steps: attraction of counter-ions and
