[Chronic right ventricular failure in a patient with diffuse toxic goiter and alcoholic cirrhosis of the liver: case description].

We present a case of a patient with pronounced edematous­ascitic syndrome. Initially, its causes were considered to be alcoholic cardiomyopathy (right ventricular failure) with heart rhythm disturbances and liver cirrhosis. Targeted treatment had a low clinical effect, which served as a basis for revising the diagnostic concept. Subsequent follow­up revealed a diffuse toxic goiter with the predominant right ventricular lesion. Achieving euthyroidism has led to a significant improvement in the patient's condition.

[Prediction of 137Cs behaviour in the soil-plant system in the territory of Semipalatinsk test site].

A mathematical model of 137Cs behaviour in the soil-plant system is presented. The model has been parameterized for the area adjacent to the testing area Ground Zero of the Semipalatinsk Test Site. The model describes the main processes responsible for the changes in 137Cs content in the soil solution and, thereby, dynamics of the radionuclide uptake by vegetation. The results are taken from predictive and retrospective calculations that reflect the dynamics of 137Cs distribution by species in soil after nuclear explosions. The importance of factors governing 137Cs accumulation in plants within the STS area is assessed. The analysis of sensitivity of the output model variable to changes in its parameters revealed that the key soil properties significantly influence the results of prediction of 137Cs content in plants.
