[Individual differences in global vs. local visual perception of hierarchical stimuli under conditions of free and forced recognition].

Sixteen adult subjects were asked to recognize hierarchical letters at either local or global levels. The experiment included two sessions, corresponding to free recognition and forced recognition with the attention directed to a specific level of hierarchy. The analysis of recognition errors and reaction time in the condition of free recognition revealed two individual strategies of visual perception: the "global strategy" (the global level was chosen more frequently) and the "local strategy" (the local level was chosen more frequently).

[Modern computer data base "necropsy protocol": potential and prospects].

Basic principles in developing computer variant of necropsy protocol with wide illustrative possibilities are presented. Perspectives in the use of this information base for research and practice and for teaching the staff of the research and clinical institutions are demonstrated.

[Interaction of DNA molecules with divalent platinum coordination complexes. II. Effect of the nature and location of ligands in the first platinum coordination sphere].

The interaction of DNA molecule with some coordination compounds of the divalent platinum: cis-DDP, trans-DDP, [(NH3)4Pt]Cl2 and K2PtCl4 was studied. It was shown that the transition of the cis-DDP, trans-DDP, and [PtCl4]2- to aquo-complexes is necessary for their binding with DNA in solution. It was shown that the labile chloride groups are responsible for the formation of the energetically strong binding.

[Study of the interaction of a DNA molecule with coordination compounds of divalent platinum. I. Effect of cis-diaminodichloroplatinum on molecular parameters of DNA in solution].

DNA interaction with cis-diaminodichloroplatinum (cis-DDP in solutions of different ionic strength was studied by flow birefringence, viscometry, circular dichroism. Though cis-DDP is not an electrolyte, electrostatic interactions are important for binding of cis-DDP with DNA probably for transporting cis-DDP to a macromolecule. The charges aqua-complex is formed by cis-DDP.
