Microelement composition of serum in Dolgans, indigenous inhabitants of the Russian Arctic, in the conditions of industrial development of territories.

The geochemical conditions of landscapes are the content in the environment of certain chemical elements and their compounds, the lack or excess of which causes deviations in the state of human health. This problem has arisen in connection with the extraction of alluvial diamonds and the forthcoming development of the Tomtor deposit of rare-earth metals in the territories where the indigenous peoples of the North live. The study included 107 indigenous people of the North, belonging to the ethnic group of Dolgans living in the village of Yuryung-Khaya, Anabar district, Yakutia of Russia.

Behavioural risk factors of arterial hypertension in the Evenk population of the Russian Arctic.

The urgency of the problem under study is determined by the high prevalence of arterial hypertension among the indigenous minorities of the North in modern socio-economic conditions. The following article is aimed to evaluate the prevalence of behavioural arterial hypertension risk factors according to the results of single-step epidemiological research of Evenk people in the Republic of Sakha (Yakutia), Russian Federation.

Lipid metabolism and feeding habits of indigenous peoples of the sakha republic (yakutia) in today's socio-economic development.

Introduction: By results of a single-step epidemiological research indicators of a lipid range at 355 Evenks of the Olenyoksky District of the Republic of Sakha (Yakutia) are estimated. The aim of this research was assessment of lipid exchange and character of a delivery of Evenks of the item of Zhilinda.

Systolic and diastolic dysfunction of the right heart ventricle in patients with chronic obstructive pulmonary disease in extremely cold climate.

The paper describes echocardiographic values of systolic and diastolic dysfunction the right heart ventricle in 229 patients with chronic obstructive pulmonary disease. In our patients the values AvPAP (?25 mmHg while resting), FDDrv and FSDrv (>26 and 20 mm respectively), the thickness of front wall the RV (>5 mm), the dimension of AD (>35 mm), as well as the reduction the vestibular-distal shortening of RV (<23%), maximum blood velocity and the blood evacuation time from reflect indirectly the progressive reduction the contractive capacity RV myocardium and the occurrence of systolic dysfunction. In patients with severe de-compensation a restrictive type diastolic function is more characteristic - acceleration of early diastolic filling and blood velocity decrease during the auricular systole.
