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.

Associations between vitamin D-binding protein (DBP) gene polymorphism (TAAA)n and development of osteoporosis in the Volga-Ural region of Russia.

Study of DBP gene (TAAA) n polymorphism in women of postmenopausal age revealed a significantly lower incidence of DBP(*) 10 allele and a higher incidence of DBP(*) 11 allele in Russian women with bone fractures in comparison with the relevant controls (χ(2) = 4.47, p = 0.034 and χ(2) = 4.

Activity of nucleolar organizers in hepatocytes of rats with cirrhosis of the liver after treatment with bioactive preparations.

The therapeutic efficiency of bioactive preparations of the liver and spleen in the treatment of experimental toxic cirrhosis of the liver is shown. Evaluation of the nucleolar organizer activity showed the highest efficiency of treatment with human fetal liver extract.

Effect of transplantation of fetal liver tissue on regenerative activity of hepatocytes in normal rats.

Regenerative activity of hepatocytes was studied in rats after transplantation of fetal liver tissue preexposed to low-intensity laser. Stimulation of the mitotic activity of hepatocytes by fetal liver tissue exposed to low-intensity laser is proven.

[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.

Reactive properties of epi- and perineurium: experimental and morphological basis for nerve suture technique.

Epi- and perineurium were examined in vitro and during regeneration after mechanical damage. Epithelial type of culture growth and reparative regeneration of the perineurium were established, connective tissue of the epineurium served as the substrate and trophic factor in these processes. We used histogenetic method of coaptation and of epi- and perineural micosutures in a damaged nerve trunk.

Experimental and clinical aspects of laser destruction of adenohypophysis.

Focal destruction of the adenohypophysis by Nd:YAG laser does not destroy other structures of the hypothalamo-pituitary region. During reparative regeneration, the focus of coagulation necrosis after laser destruction of the adenohypophysis is replaced by cicatricial tissue. A method for surgical treatment of pituitary adenomas was developed.

Experimental laser destruction of trigeminal sensory root.

The possibility of local laser destruction of the trigeminal sensory root by a puncture technique is demonstrated. A fibrous scar was formed on a limited area of the trigeminal root. There were no signs of axonal regeneration, posttraumatic neuroma, or considerable changes in the Meckel sinus.
