It is predicted that by 2020, arthroplasty of the joints of the lower extremities will exceed more than one million per year in the United States alone (2). Historically, general anesthesia has been the gold standard in orthopedic surgery. At present, in research practice and in discussing the timely prevention of cardiovascular diseases, especially coronary heart disease, which occupies the first place among the causes of population death worldwide, it is necessary to take into account age-related changes that occur in the anatomical structures of the heart and the vessels supplying it. In the References:there is evidence of agerelated changes in coronary vessels. According to (1), in people of the second period of middle age and the elderly, age-related changes in the vascular wall are noted.

To reduce the impact of toxic elements on the environment, scientists have investigated many perennial plants. These plants contribute to the release of phytoncydic substances, which help to purify the atmospheric air. You can see these trees on the streets and in parks on the territory of big cities. In the city 1 hectare of green plantations absorbs 8 kg of carbon dioxide in 1 hour, which during this time exhales 200 people.

In the F-1 and F-3 systems where viability plus selection was performed, cocoon weight values were 1.84 g and 1.85 g, and shell weights were 432 mg and 422 mg, respectively. In practice, the minus selection does not differ from those of the conducted F-2 and F-4 systems-1.72 g and 1.85 g, respectively; 394 mg and 420 mg. Clearly, the choice of viability leads to the accumulation of recessive hemispheric and subletal genes in the homozygous state in the system. As a result, some organisms die at different stages of development. But some of them survive. Probably on the one hand, because harmful genes are less accumulated, and on the other hand, because there are enough positive genes to compensate for the effects of harmful genes, i.e., the GCC is formed. Had this process not taken place, no doubt the system would have perished as a result of negative selection over several generations. It follows that GCC does not occur in systems with high viability. The predominance of positive genes over negative genes is achieved without them. In addition, the process of mutation is accelerated under the influence of negative selection.
