A map of latest positive selection in the individual genome By scanning the entire human genome in search of genetic variations that might signal recent evolution, University of Chicago researchers found a lot more than 700 genetic variants that may be targets of recent organic positive selection in the past 10,000 years of human development. In another of the first comprehensive genome scans for selection, the researchers found widespread proof evolution in every of the populations studied facial swelling causes .
Another possible cause of the appearance of puffiness on the face are diseases of the nose and its paranasal sinuses. Allergic, viral rhinitis and inflammation in the maxillary sinuses can lead to swelling of the face, including under the eyes. Especially noteworthy angioedema angioedema Quincke. It is characterized by a swollen face, then the swelling passes to the larynx and can lead to asphyxia and death. This condition requires urgent treatment: the appointment of antihistamines (Erius), if necessary - steroids (Prednisolon).
In women, the causes of puffiness in the face are often changes in the hormonal state, such as premenstrual syndrome and pregnancy. Steroid hormones that lead pregnancy, change the water-electrolyte balance, during which sodium ions are trapped in the body, entailing water.
With premenstrual syndrome, the puffiness of the eyes and face is associated with a deficiency of magnesium and vitamin B6, as well as an increase in the level of the hormone prolactin. To remove swelling in premenstrual syndrome helps a diet with salt restriction, the use of products containing potassium and magnesium (vegetables).
