[Oxidative stress, rRNA genes, and antioxidant enzymes in pathogenesis of schizophrenia and autism: modeling and clinical advices].

Ribosomal genes (RG), or genes for rRNA, are represented by multiple tandem repeats in eukaryotic genomes, and just a part of them is transcriptionally active. The quantity of active copies is a stable genome feature which determines the cell's capability for rapid synthesis of proteins, necessary to cope with stress conditions. Low number of active RG copies leads to reduced stress resistance and elevated risk of multifactorial disorders (MFD).

[Herpesvirus type 8 and its implication in human pathology].

Herpesvirus type 8 or Kaposi's sarcoma-associated virus has been recently discovered and it is an etiologic agent of several known diseases. It has common features that link it with other representatives of the family Herpesviridae: similar structural elements and genomic organization, and the common mechanisms of replication. Nevertheless, this virus has a number of unique features that make it an interesting matter for investigations and currently central in modern medicine and biology.

[Determination of genome dose of active ribosome genes and several quantitative parameters of extracellular dna in test-subjects of the experiment with 7-day immersion].

Genome dose of active ribosome genes (ARG), average of nucleolus argyrophil structures in lymphocyte nuclei, levels of extracellular DNA (DNA(e)) concentrations and ratio of antibodies to total DNA (AB(DNA)) and ribosomal DNA (AB(DNA-rib)), and nuclease activity were determined in peripheral blood of 8 volunteered subjects (21-26 y.o.) in the experiment with 7-d DI.

[Study of endothelium-dependent blood oscillations in the human skin microcirculatory bed].

Cutaneous microcirculation parameters were studied with laser Doppler flowmetry in healthy volunteers. To investigate endothelial-dependent peripheral blood flow oscillations the iontophoresis of 1% acetylcholine solution was carried out. To estimate the contribution of rhythmical components in blood flow signal the continuous wavelet-transform spectral analysis was used.

[Estimation of age-related changes in the regulation of peripheral blood flow in humans].

The age-dependent features in the state of skin microvascular bed has been studied with laser Doppler flowmetry in healthy volunteers of different age groups. To reveal the reaction of skin blood flow in response to short-term ischemia, the occlusive test has been carried out. To estimate the contribution of rhythmic components to blood flow signal, continuous wavelet-transform spectral analysis was used.
