Changes in the pulmonary circulation due to gravitational loads in high altitude conditions.

Background: The impact of gravity on the existence of all living things has long been of interest to scientists. The force of the Earth's gravity combined with hypoxia significantly affects blood circulation and blood accumulation in various parts of the human and animal body. To date, the relationship between body position and blood circulation in pulmonary circulation under hypobaric hypoxia has not been sufficiently studied.

Acute Coils Migration Causing Significant M3 Branch Occlusion: A Case Report of Rescue Surgery with Superficial Temporal Artery-Middle Cerebral Artery Bypass.

We describe an uncommon case of acute coils migration with significant occlusion of M3 branch and our management of this complication. Ballon-assisted coil placement was performed for an unruptured intracavernous internal carotid artery aneurysm in a 62-year-old woman. After coil placement and balloon deflection, we observed coils migration with significant occlusion of M3 branch.

[POPULATION AND CLUSTER APPROACH TO ASSESSMENT OF REPRODUCTIVE HEALTH OF WOMEN].

The purpose of this study was to explore the possibility of using a population approach to assessing the risk of reproductive health disorders in women of childbearing age. We observed 240 clinically healthy women aged 20 to 43 years, half of them lived in the Middle Black Earth region of Russia, and 120 women lived in Tajikistan. The study identified population differences in women with different ethnic backgrounds and regions of residence according to a set of genetic, hormonal, and immune signs.

[On mechanism of functional changes in the organism of teenagers at different levels of locomotor activity].

Comprehensive study of the cardiovascular system functional condition of 15-16 teenagers while in normal daily locomotor activity and in the mode of regular moderate physical activity was performed. The features of cerebral circulation and myocardium functional condition of teenagers are studied depending on initial tonus of the autonomic nervous system and locomotor activity level in the process of continuous step physical activity on tredmil. The condition of regulatory mechanisms, providing adaptation of teenagers in the conditions of modern school was studied.

[Dynamic structure of the cardiac rhythm in the process of adapting to high-altitude hypoxia].

On the basis of dynamic series of RR intervals of electrocardiograms of healthy male test subjects exposed for a different period of time to high altitude hypoxia, autoregression clouds were built. The patterns of distribution thus obtained were compared with physical work capacity of the test subjects. It is suggested that when selecting people to work actively at high altitudes autoregression clouds can be used as quantitative estimates of their health state and as predictions of potential adaptation failures.
