Analysis of the efficiency of recombinant Escherichia coli strain cultivation in a gas-vortex bioreactor.

The levels of aeration and mass transfer are critical parameters required for an efficient aerobic bioprocess, and directly depend on the design features of exploited bioreactors. A novel apparatus, using gas vortex for aeration and mass transfer processes, was constructed in the Center of Vortex Technologies (Novosibirsk, Russia). In this paper, we compared the efficiency of recombinant Escherichia coli strain cultivation using novel gas-vortex technology with conventional bioprocess technologies such as shake flasks and bioreactors with mechanical stirrers.

[Comparative assessment of conservative treatment of chronic prostatitis with application of complex unit andro-gin].

The Andro-Gin unit used in combined treatment of 78 patients with chronic prostatitis (CP) and 16 women with chronic interstitial cystitis with inflammation in the internal genitalia (56.5% of the patients had sexual and spermatogenesis disorders) employed effects of simultaneous exposure to local magnetic field, electrostimulation of the small pelvis organs and prostate with introduction of contact rectal electrode, neurostimulation of pathogenic zones, low-intensity laser and light-diode radiator and color impulse therapy. Control group consisted of 85 patients with CP who received conventional physiotherapy.

[Technical realization of an experimental model of a resonance mechanism of activating oxygen transport and consumption by hepatocytes].

The authors review problems of oxygen regimen of the body under conditions of extracorporeal circulation. Provide the experimental data on the dynamics of oxygen consumption. Draw a based conclusion about a new approach to elaboration of the requirements for extracorporeal circulation systems.

[Structural organization of double-stranded RNA from killer yeasts Saccharomyces cerevisiae by the thermal denaturation method].

The thermal denaturation method for studying the structural organization of double-stranded RNA (dsRNA) from virus-like particles of killer yeasts Saccharomyces cerevisiae was used. High resolution derivative denaturation profiles of total dsRNA and its L- and M-types were obtained. Comparative analysis of these data with those on phage DNA denaturation demonstrated that the processes of denaturation of dsRNA and phage DNA were identical in quality.
