RESUMO
Experimental data on dielectric function and dielectric loss tangent in living and non-living water-containing systems have been discussed from the viewpoint of our earlier concept on energy transfer in living systems and the role of water in this process. Estimates have been made of a mean length of fractal quasi-crystals, representing the form of biomolecules hydration in the living system; the expected lengths of these quasicrystals are of order of 1000 H2O molecules. It is concluded that the peaks at the curve of frequency dependence of dielectric loss tangent in living systems is due to water sub-system, but not biomolecular vibrations.

The physical aspects of the ERIAD method (electrospray with controlled fragmentation) in terms of the problems of metallomics and biochemistry of elementoorganic compounds have been considered. It was shown that the method is well suited to study the objects of this class since it enables one to change from the molecular to the elemental analysis merely by changing the voltage between the nozzle and the skimmer. In the regime of molecular analysis, it is possible to determine the mass of the molecule as a whole and decipher its structure by controlled fragmentation, and in the regime of elemental analysis the number of atoms of heteroelements incorporated in the molecule can be quantified.

Possible mechanisms of action of weak combined magnetic fields on biological systems have been discussed in terms of quantum mechanics. The approaches proposed make it possible to solve the problem of the failure to compare the energy of active factors with the energy of thermal motion (kT problem). A mechanism of action of combined magnetic fields on biosystems has been proposed.
