Impact of Environmental Radiation on the Incidence of Cancer and Birth Defects in Regions with High Natural Radioactivity.

Four regions of high natural radioactivity were selected to assess radionuclide levels in rocks and soils, ambient radiation doses, radon exhalation from the ground, and radon concentrations in the air. The regions have different geochemical characteristics and radioactivity levels, which modulate the radiation exposure of local populations. Combining radiometric data with data from regional health statistics on non-infectious diseases, a statistically significant positive correlation was found between radiation exposure and the incidence of cancer and birth defects.

Influences of geological factors on the distribution of uranium in drinking water limescale in the junction zone of the East European Platform and the Southern Urals.

An assessment of uranium contents and distribution in drinking water limescale has been conducted in the Republic of Bashkortostan (RB), Russia. A total of 515 limescale samples from 262 settlements of the RB were analyzed. The spread of U concentration values in limescale samples ranged from 0.

Possible mechanisms for the effect of protein sensitization on functional properties of the isolated m. soleus and m. EDL from mice.

We studied possible involvement of ATP in the influence of protein sensitization on contractile function and non-quantum secretion in the end-plate of isolated skeletal muscles from mouse leg. The dynamic vector of muscle contraction force was shown to correlate with changes in non-quantum secretion of acetylcholine under various conditions of experimental pathology. However, the degree of these changes was lower in sensitized animals.

Change in lymph flow during low-grade fever and febrile fever under experimental conditions.

Experiments on rats showed that low-grade fever is accompanied by a decrease in the central lymph flow rate, which results from inactivation of lymphangion components in lymphatic microvessels of the small intestine mesentery. Lymph flow rate was shown to increase during pyrogenal-induced fever, which did not depend on the duration of the disease.

[Application of high information technologies in predicting outcomes of cardiovascular diseases].

The authors review their studies conducted for many years on cardiological prognostication in the context of the republican program "Cardiology" performed in the Udmurt Republic. The lines of the research and results obtained are described.
