The trials performed in the rats revealed that the creation of conflict situations, in the presence of two different motivations simultaneously, results in increase in anxiety state in animals. In terms of evolving and stabilizing the two active avoidance responses in animals, the three cohorts of different learning abilities (good, average and poor) were(More)
Although the majority of the literature supports the concept that an accumulation of DNA damage or a modification in the DNA structure of postmitotic cells occurs with increasing age, there are also several reports that show no DNA changes in these cells with increasing age. In the study reported here, two components of the DNA damage hypothesis of aging(More)
The dynamics of various forms of RNA-polymerases of the rat's brain was studied in the course of postnatal development, using autoradiography and fractionation of enzyme preparation purified from the matrix DNA admixture. In the brain of new-born rats, synthesis of ribosomal RNA proceeds more intensively, with form I enzyme being most active, due to a most(More)
The percent of mitochondrial protein contamination in nuclei decreased 10-fold (from 18 to 1.8%) under purification of protein-labelled mitochondria before their introduction into nuclei-free homogenate, cytochromoxidase activity being unchanged. Thus, cytochromoxidase activity of nuclei does not correlate with the amount of nuclei-adsorbed mitochondrial(More)
