Novel cost-efficient protein-based membrane system for cells cocultivation and modeling the intercellular communication.

In vitro systems serve as compact and manipulate models to investigate interactions between different cell types. A homogeneous population of cells predictably and uniformly responds to external factors. In a heterogeneous cell population, the effect of external growth factors is perceived in the context of intercellular interactions.

Site-specific concentration of uranium in urine of workers of the hydrometallurgical plant of Stepnogorsk mining and chemical combine.

Radiation monitoring is an important radiation safety measure implemented at the hydrometallurgical plant of the Stepnogorsk mining and chemical combine (HMP SMCC, Republic of Kazakhstan). Follow-up of the workers and their regular medical examinations has laid the basis to create a cohort with the potential to be used in radiation epidemiology. The aim of current pilot study was to analyze the dose forming factors for workers of HMP SMCC.

[Experience of the usage of non-pharmacological methods in a multimodality treatment of tension headache].

Objective: To evaluate the efficacy of the non-drug therapy based on neurofeedback as a part of multimodality treatment of tension headache.

Material And Methods: Neurofeedback trainings, which were supported by sensory room sessions, were performed. Two equal groups, with 40 patients in each group, with clinical manifestations of tension headache received pharmacotherapy and non-drug therapy (main group) or pharmacotherapy (comparison group).

RADIATION SITUATION IN THE TERRITORIES AFFECTED BY MINING ACTIVITIES IN STEPNOGORSK AREAS, REPUBLIC OF KAZAKHSTAN: PILOT STUDY.

The Republic of Kazakhstan has a long history of mining activities, viz., gold and uranium. Mining activities represent sources of potential naturally occurring radionuclides contamination of the environment and human health of population.

[Evaluation of the effect of dose rate and dose absorption on the long-term radiation consequences in rats chronically taking in 90Sr].

The effects of exposure to 90Sr which was given with food with daily doses 18.5 kBq per animal for 1-12 months, 37 kBq per animal for 1-10 months, 74 kBq per animal for 1-8 months and 148 kBq per animal for 1-6 months on mortality patterns in unimbred white rats were investigated. Hazard models were used to evaluate dose rate and accumulated dose influence on radiation-related trends in mortality.

[Analysis of DNA status in bone marrow cells of mice internally irradiated with 90Sr ].

The response of bone marrow cells of CBA mice injected with 22.2, 222 and 592 kBq/animal to additional gamma-irradiation (3 Gy) for testing purposes was evaluated using SCG (Comet assay). A decrease in induction of DNA damage right after additional gamma-irradiation was determined.
