[Transit of radiocesium and radiostrontium from the fallout to the soil of the Ukrainian S.S.R. due to the Chernobyl AES accident into plants and milk].

Dietary components making a great contribution to the formation of human internal irradiation dose were defined. The values of soil-milk transition ratios that are ranging 0.3 to 41 E-9 MBq.kg-1.Bq-1.m2 have been obtained from the examination of 1300 milk specimens by radiochemical assay for 90Sr. The relationship of soil-milk and soil-plant transition ratios was examined to the type of soils and the distance from the NPP.

[Recombinant thymosin alpha1].

An artificial gene encoding thymosin alpha1 was obtained by the chemoenzymatic synthesis and cloned into Escherichia coli. An expressing recombinant plasmid containing the hybrid protein gene, which encodes amino acid sequences of thymosin alpha1 and the Saccharomyces cerevisiae intein Sce VMA, was constructed. The expression of the hybrid protein from the resulting hybrid gene in E. coli, the properties of the resulting hybrid protein, and the conditions for its nonenzymatic cleavage to thymosin alpha1 were studied. The English version of the paper: Russian Journal of Bioorganic Chemistry, 2004, vol. 30, no. 5; see also http: // www.maik.ru.
