Color blindness is a violation of the color perception of vision. Simply put, color blind is a person who does not distinguish between certain colors or shades. According to statistics, every tenth man on our planet is color blind. The only difference between them is the type of violation, due to the number of colors that they can recognize. In the article we will deal with the features, causes and correction of color blindness. You can pass a special test for the perception of colors, with which a deviation is detected.
The concept of “color blindness” came about thanks to John Dalton, an English physicist and chemist who himself learned about his color perception disorder as an adult at age 26. This was due to his passion for botany. When studying the flower, he noticed that in daylight the plant seemed sky blue to him, and in the evening light with a candle the flower turned dark red. Such a metamorphosis was not noticed by anyone around, except the scientist’s brother. Then Dalton began to realize that his vision was not in order and this phenomenon was hereditary.

Chronic tonsillitis (CT) is common after a recent sore throat. It can also provoke any other infectious disease in which inflammation of the throat mucosa has been observed. Often people confuse chronic tonsillitis with angina. In fact, angina is the popular name for acute tonsillitis, which usually precedes the chronic form. In chronic tonsillitis, the lymphoid tissue of the tonsils of the pharynx is affected. In rare cases, the focus of infection can be localized on the tonsils, or lingual. An acute inflammatory process is observed, which is repeated throughout the year. Most often, children are affected by an illness, ranging from 15 to 63% of cases, depending on the time of year. Treatment should be started immediately, as other diseases develop against the background of the ailment. Among them are diseases of the skin, eyes, kidneys, and thyroid gland.
Causes of Chronic Tonsillitis (CT)
The root cause of chronic tonsillitis is infection. Most often, pathogens are: staphylococci, streptococci, pneumococci, Epstein-Barr virus, herpes virus, hemophilus bacillus, chlamydia, fungi. What could precede the disease? Continue reading
Many pregnant women, instead of enjoying their excellent position, concentrate on diseases, sometimes extremely rare, like toxoplasmosis. In order to alleviate unnecessary anxiety and arm yourself with valuable recommendations for the prevention of toxoplasmosis, we will talk about this infection, its specifics during pregnancy, as well as discuss tests and treatment.
Toxoplasmosis during pregnancy
Toxoplasmosis is a parasitic (non-viral and non-bacterial) disease that causes the multicellular parasite Toxoplasma gonii. An extremely unpleasant infection to carry during pregnancy. The parasite lives and multiplies in the cat family, and other mammals, including humans, can be an intermediate host.
Toxoplasmosis is common in warm countries (South America, Asia), so for Russia it is considered a “forgotten” disease. However, 20% of the population of our country have the presence of antibodies-immunoglobulins in the blood, which indicates contact with this parasite in the past. Continue reading
Heartburn is an unpleasant burning sensation in the chest and heart area that many have experienced after eating. This feeling can be disturbing for several minutes or even hours, causing discomfort and pain. When there are no modern drugs for heartburn at hand, folk remedies that are easy to use at home can help get rid of it. About five effective methods, safe methods of their use and contraindications, we described in the article.

Be careful when choosing the method that is right for you to avoid allergic reactions and other side effects. Continue reading
Scientists from Russia and the United States have proposed new material for regenerative medicine. The compounds in the composition of this material literally “turn off” the work of enzymes that are responsible for the inflammation reaction that occurs in immune cells in response to external stimuli. The results of the researchers’ work are published in the journal ACS Biomaterials Science & Engineering.
“At the moment, researchers do not have a lot of tools to regulate the immune response in the arsenal. Continue reading
