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.

[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.
