Interventions

30 ml of venous blood will be collected from all voluteers using a special vacuum tubes after informed consent. Blood sampling is carried out from an arm vein. All subsequent studies will be executed in the laboratory diagnostic division of Novosibirsk Research Institute of Circulation Pathology and the presence of the donors is unnecessary
