EEG correlates of language development in orphans under the age of three and a half  years
The results of study correlations level of speech development and the power spectral density of the current  EEG rhythms in children and orphans. Considerable delay in speech development may be due to  underdevelopment of the associative fields of the brain responsible for processing complex information and  the integration of different parts of the cerebral cortex. This delay in the maturation of neurons, probably  connected with the stay of the child in terms of anti-social before entering the child's home, as well as the  conditions of social deprivation in which the child is placed.

The influence of extremely low frequency magnetic field on structurally-functional  properties of different proteins
It was shown that the effect of the magnetic field (MF) on intrinsic fluorescence of serum albumin depends on the frequency of the field. MF accelerates the decline of the ATP-ase activity of actomyosin due to increased  protein aggregation and changes in its temporal dynamics. The effect of this physical factor on the structural  and functional properties of proteins has been more significant in terms of their interaction with hydrophobic  ligands. The combined impact of the MF and chloroform reduces oxidative capacity of cytochrome c in the  first hours of the MF-exposure. MF inhibits the process of renaturation of methemoglobin interactied with benzene and chloroform in the first four hours of action but does not lead to significant changes in the long  daily exposure.
