To determine the current risk of internal radiation exposure after the Chernobyl accident, the (137)Cs body burden of the inhabitants of Bryansk Oblast, Russian Federation was evaluated, from 1998 to 2008. The study population is composed of 84 666 people who visited Bryansk No. 2 Hospital. A whole-body counter was used for measurement of (137)Cs body burden. (137)Cs concentration was significa...

Dirac equation for the finite dipole potential is solved by the method of the join of the asymptotics. The formulas for the near continuum state energy term of a relativistic electron-dipole system are obtained analytically. Two cases are considered: Z < 137 and Z > 137 Dirac equation for Z > 137 is solved by usual method of cut-off potential at small distances.

Recent years have seen increasing interest in the potential for using caesium-137 as a tracer in soil erosion investigations and caesium-137 measurements are now accepted as an effective and valuable means of producing retrospective information on medium-term rates and patterns of soil redistribution. There are, however, two important limitations to the general application of the approach. Thes...

ERRα is an orphan nuclear receptor emerging as a novel biomarker of breast cancer. Over-expression of ERRα in breast tumor is considered as a prognostic factor of poor clinical outcome. The mechanisms underlying the dysexpression of this nuclear receptor, however, are poorly understood. MicroRNAs (miRNAs) regulate gene expression at the post-transcriptional level and play important roles in tum...
