The article substantiates the need to study the development of one-year saplings from cuttings of almond willow (Salix triandra). Purpose of research: identification and analysis of seasonal dynamics of daily growth of shoots in S. triandra clones against the background of excessive atmospheric moisture in the form of three showers in 2020. Material and methods. Research methods: selection, structural-morphological, chronobiological. Object of research: model inbred-clone one-year population of S. triandra. The number of clones is 7; the recurrence is 6-fold. Material: growing annual shoots on one-year saplings; each sapling was formed into a single shoot. Results. Under experimental conditions, the rooting capacity of cuttings was 100%. Dimorphic root systems were formed on the mother cuttings of the excavated seedlings. The annual growth of the strongest shoots was 175 ... 215 cm. The daily growth in shoots reached peak values by June 10: the average daily growth was 3.6 cm/day, the maximum — 4.4 ... 4.9 cm/day. After June 10, the daily growth rate decreased unevenly until the end of the growing season. Some shoots completed growth before the beginning of August, and some continued growth until the middle of August. The cyclical nature of the seasonal dynamics of daily growth in the form of three peaks separated by two dips is established. The third peak is formed after the third rainstorm. Discussion and conclusions. Cyclical seasonal dynamics of daily growth of shoots is characterized by a high degree of synchronization of growth processes. Probably, all the shoots are affected by some powerful pulse synchronizer of unknown nature. It is possible that periodic showers may have a modifying effect on the mechanisms that regulate growth processes. The temporal discreteness of shoot morphogenesis is due to the full or partial realization of the seasonal cycle of shoot development. The duration of growth is due to interclonal and intraclonal differences. Probably, the duration of morphogenesis is controlled by both genetic and epigenetic factors.

The new modern world has entered a complex society. Nature its new material world of the Universe and its natural habitat, become more variable, over shorter periods of time. The system of nature–society–human is a holistic, dynamic, wave, open, steadily non-equilibrium system, with the isolation not only of internal ties, but also of external ones - with the space environment. Modern science views man, humanity and the biosphere as a single system, with growing demographic, food and medical problems. Human brains are biological, biophysical, neurophysiological and medico-social paradigms of information exchange. Modern communications are multilevel, multi-paradigm and interdisciplinary models of information exchange. The new competencies of psychoneuroimmunoendocrinology and psychoneuroimmunology play a strategic role in interdisciplinary science and interdisciplinary planning and decision-making. The introduction of multi-vector neurotechnologies of artificial intelligence and the principles of digital health care will contribute to the development of modern neuroscience and neuromarketing. The introduction of biocomputer nanoplatforms and modules consisting of small molecules, polymers, nucleic acids or proteins/peptides, nanoplatforms are programmed to detect and process external stimuli, such as magnetic fields or light, or internal stimuli, such as nucleic acids, enzymes or pH, using three different mechanisms: system assembly, system disassembly or system transformation. Current biocomputer nanoplatforms are invaluable for many applications, including medical diagnostics, biomedical imaging, environmental monitoring, and delivery of therapeutic drugs to target cell populations. Integration of different sources of information will allow researchers to obtain a new holistic picture of the pathophysiological process of the disease, which will cover from molecular changes to cognitive manifestations. Cognitive memory is a continuous act of creation, one of the largest and most capacious concepts that represents the main function of memory in general. The knowledge that a person receives during training is first perceived as something external, but then gradually they turn into experience and beliefs. Cognitive memory retains all the knowledge gained, representing a kind of “library”, and the process of assimilation and preservation becomes more complicated as the information received becomes more complex.

The United Nations General Assembly in 2012, at its 66th session, recognized that oral diseases pose a serious health problem for many countries. The European Health Commission has proposed 40 dental health indicators to assess the main criteria for dental status, achievements in prevention and possible risk factors for dental diseases. Dental caries are one of the most pressing problems of pediatric dentistry not only in the world, but also in the Kyrgyz Republic. Unfortunately, in Kyrgyzstan, the incidence of caries remains stable at a high level. Finding and applying effective methods and approaches to the diagnosis of early manifestations of caries in children is a relevant and important point. Therefore, timely diagnosis of caries at the age of 6–7 years prevents the transition of initial forms of caries to carious defects, and in the future eliminates the use of invasive methods of surgical restorative treatment. Regular assessment of the possible impact of behavioral risk factors for dental caries in school-aged children should be a mandatory component of monitoring the medical effectiveness of prevention programs. Through primary and secondary dental caries prevention programs in children, it is possible to approach the best international standards for the quality of dental care for children. The solution to the problem of high incidence of dental caries in children is possible only if the preventive focus of school dentistry, consisting in hygienic education and education of schoolchildren, is prioritized. The importance of a comprehensive approach in solving the problems of pediatric dentistry lies in improving the effectiveness of the dentist and the quality of services provided.

In studies Romanchuk N.P. from invention in 2010 [68] (consisting in increasing the preventive effect on the human body through the introduction of vital food substances into a functional food product to suppress free radical activity, invasive detoxification of the human body, optimizing neurogenic regulation of vascular tone in arterial hypertension and restoring reproductive functions in males and females by optimizing the quality structure of product components), to the present [69] it has been shown that a new managed healthy biomicrobiota and personalized functional and balanced nutrition of the “brain and microbiota” is a long-term medical program of the patient, which allows the combined use of nutritional epigenetics and pharmaceuticals, and most importantly the prevention of polypharmacy. The main engine of human longevity is when microbiological memory remains stable, and the diet of functional (healthy) dietary nutrition and the structure of healthy biomicrobiota function almost unchanged. The human microbiome is a collection of all microbes that inhabit the body. The human gut microbiome is a unique collection of microorganisms that affect a number of important processes: from metabolic and immune to cognitive, and deviation of its composition from the norm leads to the development of various pathological conditions. Harmful changes in the composition or number of gut bacteria, commonly referred to as intestinal dysbacteriosis, have been associated with the development and progression of numerous diseases, including cardiovascular (CVD) diseases. Most CVD risk factors, including aging, obesity, certain dietary patterns, and sedentary lifestyles, have been shown to cause bowel dysbiosis. Dysbacteriosis is associated with gut inflammation and reduced gut barrier integrity, which in turn increases levels of circulating structural components of bacteria and microbial metabolites that may contribute to CVD development. The purpose of the present review is to summarize available data on the role of the gut microbiome in the regulation of cardiovascular function and pathological processes. Particular attention is paid to dietary-related microbiome changes, as well as cellular mechanisms by which the microbiome can alter CVD risk.

Modern psychological studies of communicative competence indicate the need to improve and maintain the proper level of this skill, adequate and productive interpersonal interaction. Communication competence — the ability to establish and maintain the necessary contacts with other people. Effective communication is characterized by mutual understanding of partners, a deep understanding of the situation and the subject of communication. So as to save citizens from disability is not enough to create specific health and social conditions, according to the who, health only 10% depends on the state of health — one of the main factors in maintaining the optimum degree of effectiveness of remedial measures becomes a subjective factor of interpersonal interaction between doctor and patient. Each patient under the influence of external circumstances (financial situation, family relations, medical and preventive care, etc.) and psychological factors develops their attitude to the disease, which does not always coincide with the doctor's recommendations, which can lead to conflicts in therapy. Doctor–patient interaction is also a process of communication in which a positive therapeutic Alliance must be formed, otherwise, in the presence of confrontational moods, effective cooperation in the doctor-patient dyad becomes unattainable — the patient’s recovery becomes at risk.

Limiting a person’s lifestyle to objective social conditions is usually due to the fact that they determine the essence and nature of people's life activities. However, not only social, but also natural factors determine people’s life activity. The article shows that the way of life of people can be studied only in unity with the conditions of life. Its essence should be revealed taking into account the influence of natural and social conditions on it. This means that the concepts of “living conditions” and “lifestyle” are inseparable, but it does not mean that one of them becomes an integral part of the other. In fact, living conditions, or rather the natural and social spheres, only describe the possible range of people’s activities. It is emphasized that not only living conditions shape the way of life of a person, but he himself changes the surrounding conditions, both social and natural, during his life.
