В обзоре рассмотрены результаты отечественных и зарубежных исследований, направленных на выяснение роли гамма-ритма биоэлектрической активности мозга в обеспечении высших психических функций у человека в норме и при неврологических и психических заболеваниях. Проанализирована динамика гамма-ритма в процессах сознания, внимания, памяти, зрительно-моторной координации, когнитивной деятельности, медитации. Представлены данные о значении гамма-диапазона ЭЭЕ в генезе пограничных расстройств, психических и неврологических заболеваний, в том числе синдроме дефицита внимания с гиперактивностью, биполярных расстройств, депрессии, аутизма, шизофрении, болезни Альцгеймера, эпилепсии и инсульта. Дальнейшее изучение изменений гамма-ритма и их взаимосвязи с нарушениями ЦНС позволит существенно расширить современные представления о патофизиологических механизмах и роли высокочастотных осцилляций в обеспечении функций мозга.

The review summarizes and analyzes specters of therapeutic effect of laser and light-emitting diode radiation of different wavelengths as exemplified by various diseases. The physiological and certain biophysical differences in the basis of effect mechanisms of modern laser and light therapy are emphasized. The review applied both research studies and monographs and tutorials. Hence, a large volume of data was analyzed concerning every type of light therapy and its contraindications. The comparison is implemented concerning efficiency of implementation of red, blue and green light-emitting diode radiation in neurological, therapeutic, stomatological practice and in therapy of emotional conditions.

The review presents analysis and generalization of studies concerning therapeutic effect of interrupted pneumo-compression. The physiological differences underlining mechanisms of effecting of ascending and descending pneumo-compression are emphasized. The comparison with static pneumo-compression is carried out. The various technical approaches to application of pneumo-compression and molecular aspects of involvement of fibrinolytic mechanisms into effects of interrupted pneumo-compression are analyzed. The review uses both national and foreign scientific studies and monographs and tutorials. This comprehensive approach permits to analyze sufficiently wide specter of data confirming efficiency of preventive application of interrupted pneumo-compression for preventing thrombosis of deep veins and thromboembolism of pulmonary arteries.

The article substantiates the relevance of the development of the marketing logistics system, the logistics approach to assessing the competitiveness of the enterprise, as well as solving methodological problems of managing logistics business processes and meso-competitiveness. In order to identify its specifics and indicators, study its impact on the economic efficiency of the enterprise, a comparative analysis of the experience of companies practicing marketing and logistics tools for assessing and ensuring competitiveness was carried out using methods of theoretical and empirical research, systemic and statistical analysis. The company's competitiveness assessment was carried out on the basis of a set of indicators, including marketing and logistics processes. They made it possible to define logistics guidelines as a scientific and practical activity for safe strategic management of enterprise competitiveness in order to minimize logistics costs and commercial risks, optimize the company's logistics system and increase its profit and profitability. The need to integrate the groups of practices used in assessing the competitiveness of an enterprise as a link in the supply chain is justified.
