Their mechanisms of action and characteristics of incentives in different biological structures are studied insufficiently. The actuality of work is due to thepresence of a wide range of pathological and limiting states that are subjected to treatment through physiotherapeutic effects on various parts of the nervous system, which is confirmed by studies of leading universities of the world and a significant interest of users of typical devices for: rapid recovery of physical condition (replacement of pharmacological agents); stimulation of physical abilities of an organism (training of athletes); stimulation of mental abilities (preparation for examinations); treatment of speech impairment in the sensitivity of psychological and emotional state. An analysis of the paths of current propagation with non-invasive effects requires the consideration of possible biophysical mechanisms of the effect of weak current on the brain through the ankle electrodes. The amount of energy supplied to the patient and the depth of the signal penetration is a factor in the effectiveness of stimulation, because due to the correct choice of these parameters, the period of treatment decreases and the effectiveness of the procedure increases. The basic principle of neurostimulation is to obtain an optimal physiological effect under the condition of minimal side effects, which determines the use of different currents, depending on the tissue excitability and their functional state. The physical bases of transcranial stimulation by direct current areanalyzed in the article. The equivalent electrical scheme of the model of the investigated object is substantiated. The behavior of biological structures is described by an equivalent electric circuit, the resistors and capacitors of which correspond to the resistance and capacitance of the membrane and the intercellular fluid. The construction and modeling was carried out in Micro-Cap 9.As a result of a computer experiment, it became clear that a cell conglomerate can be replaced by one equivalent cell: the nature of the impedance curve does not change, and only its spreading varies","PeriodicalId":386518,"journal":{"name":"Біомедична інженерія і технологія","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115096513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Appearance makes it possible to have a good life. Unfortunately, a large number of people have skin problems that begin from a young age, and this entails not only psyhologycal, but also material problems.There is a wide choice of ways to treat skin defects. There is a wide range of creams for different skin types and for dealing with various skin problems. Even special sets-complexes for skin care of the face are created. There are also various more effective hardware treatment techniques, such as ultrasonic cleaning, laser peeling, injection mesotherapy, electroporation. To date, electroporation is used in a variety of areas, for example, in medicine for the treatment of cancer, in biotechnology to create hybrids, in cosmetology for the delivery of drugs to the cells. Wherever this method is used, it is always based on the effect of electromagnetic pulses on the cell membrane to form pores of the required dimensions. Recently, the electroporation method has become widely used in cosmetology, as a method of non-injection mesotherapy. During electroporation in the bilayer lipid membrane, a local restructuring of the structure occurs, leading to the appearance of reversible through water channels. This method promotes faster penetration of necessary substances (drugs, vitamins) inside. This technique increases cell permeability by 400 times. In this case, about 90–100 % of the active substances penetrate. This method is completely non-invasive and painless. Provides a visible effect after the first procedure, and it does not take time to restore the skin after the procedure, since it does not cause any noticeable irritation.The method has shown its effectiveness in solving a variety of problems, such as: age-related skin changes, acne treatment, and restoration of elasticity and water balance of the skin, cellulite treatment.","PeriodicalId":386518,"journal":{"name":"Біомедична інженерія і технологія","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129393529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper considers the form of ventricles in the form of conic membranes, which is more in line with reali-ty. This allowed to determine the maximum stresses occurring in the walls of the ventricles, which depend on their anatomical form and level of filling with blood, thus, determine the zone of application of external pressure in the direct heart massage. Thus, the obtained results allowed to develop a more precise computer model of the lower parts of the heart, which in turn allows us to propose a new technical solution for intraperitoneal device to support the pumping function of the heart.","PeriodicalId":386518,"journal":{"name":"Біомедична інженерія і технологія","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124078756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
