Characteristics of the Gut Microbiota Composition of the Arctic Zone Residents in the Far Eastern Region.

. In many studies over the past decade, scientists have made a connection between the composition of gut microbiota and human health. A number of publications have shown that gut bacteria are involved in many metabolic and physiological processes of the organism.

[The ultrastructure of Sertoli cells and spermatogonia in the rats exposed to radiation under conditions of therapeutic and prophylactic application of low-intensity electromagnetic emission].

Background: it has been demonstrated in various experimental studies that radiation exposure produces a negative impact on the processes of spermatogenesis associated with the disturbances of the microcirculation processes in the testes and the development of cellular and intracellular disintegration expressed as destructive changes in the cells leading to their death.

Aim: The objective of the present study was to detect the ultrastructural abnormalities in the cells of Sertoli and spermatogonia under conditions of their exposure to radiation and to identify the peculiarities of their regeneration under the influence of the therapeutic and prophylactic application of low-intensity ultra-high frequency (UHF) electromagnetic radiation (EMR) and low-intensity low-frequency magnetic field (MF).

Material And Methods: The experiments were carried out on 28 non-pedigree mature male rats with the body weight 180-220 g that were divided into four groups.

[The prospects for the development of regenerative physical therapy].

The review is concerned with the investigations into the influence of physiotherapeutic factors on the regeneration of the muscular, nervous, bone, and epidermal tissues; also, it analyses the publications pertaining to the influence of low-intensive physiotherapeutic modalities on the migration rate, proliferative activity, and differentiation of stem cells as well as physiological stability and viability of these cells following their transplantation. The currently available data give evidence of the possibility in principle of the combined application of physiotherapeutic factors and cellular technologies in regenerative medicine and the prospects opening for the development of the new direction of research in modern biomedicine, namely regenerative physical therapy. The importance of interdisciplinary basic and clinical investigations in this direction becomes especially evident in the light of the recent achievements and rapid progress in the development of modern regenerative medicine.

[The application of low-intensity electromagnetic radiation under immobilization stress conditions (an experimental study)].

The experiments carried out on outbred male white rats with the use of optical, electron-microscopic, biochemical, and radioimmunological methods have demonstrated that the application of low-intensity electromagnetic radiation (LI-EMR) with a flow density of 1 mcW/cm2 and a frequency of around 1,000 MHz both in the primary prophylaxis regime and as the therapeuticpreventive modality arrested the development of post-stress disorders in the rat testicles, liver, and thymus; moreover, it promoted activation of the adaptive, preventive, and compensatory processes. The data obtained provide a rationale for the application of low-intensity electromagnetic radiation to protect the organism from negative effects of stressful factors.

[The biotropic weather conditions and changing the clocks as the extraneous risk factors of weather-dependent exacerbations of chronic diseases].

This paper reports the results of medico-meteorological investigations suggesting the influence of biotropic (unfavourabe) weather conditions characteristic of transient seasons in combination with the abolition of on the frequency of application for emergency medical aid. It was shown that the abolition of during the period from 2009 to 2013 resulted in a significant rise in the frequency of application for the emergency treatment of exacerbation of cardiovascular diseases. The sociological studies involving the responders of various social and age groups carried out parallel to the medical ones demonstrated that most of them (77%) considered the abolition of to be the main cause of the deteriorated of the sense of wellbeing and emphasized the necessity of winter time reversal.
