[The evaluation of the effectiveness of cardiac rehabilitation of the patients after percutaneous coronary interventions]. / Otsenka éffektivnosti kardioreabilitatsii patsientov posle chreskozhnykh koronarnykh vmeshatel'stv.

BACKGROUND: Notwithstanding the current abundance of the methodological approaches to the evaluation of the outcomes of medical rehabilitation, the criteria for the effectiveness of the combined influence of the curative physical factors are still inadequate and remain at variance with the principles of evidence-based medicine. AIM: The objective of the present study was to develop a method for the evaluation of the effectiveness of the rehabilitation activities in the patients presenting with the acute coronary syndrome following endovascular cardiac interventions. MATERIAL AND METHODS: This work is based on the results of a prospective single-center cohort-based clinical study involving the subjects who had undergone myocardial infarction following endovascular cardiac surgical interventions. The duration of the patient's participation in the study was 21 days. RESULTS: We have developed the integrative approach to the creation of the unified multi-criteria system for the evaluation of the effectiveness of the treatment of the patients presenting with cardiovascular diseases after percutaneous coronary interventions (PCI). In addition, the step-by-step description of this technology is presented. The algorithm for the calculation of the integrated health index and the evaluation of the overall effect of the rehabilitation activities was proposed based on the assessment of the clinical, laboratory, and functional indicators of the health status together with the psychological characteristics of individual patients. It is proposed to consider an integrated health index as a parameter for estimating the rehabilitation potential of the patients suffering from cardiovascular diseases after percutaneous surgical interventions. CONCLUSION: The proposed system for the evaluating of the effectiveness of comprehensive medical rehabilitation differs from analogous intellectual products in that it excludes the subjective interpretation of the severity of clinical symptoms associated with the concrete pathological process and makes impossible the arbitrary determination of the weight of the peculiar features of the patient's condition. Moreover, it allows to reduce the parameters of different types chosen as the criteria for the evaluation of the effectiveness of rehabilitation to the standardized values, to obtain an unambiguous numerical expression of the results of the rehabilitative treatment, and to compare the outcomes of the rehabilitation activities based at different treatment and prevention settings.

[Bion-M1. Biological activities of microorganisms under the conditions of a 30-day space flight].

It was stated that spaceflight factors (SFF) affect the chromosomal DNA interchange during Streptomyces crossing. Cross polarity and primary input of a parent chromosome fragment in recombinant generation imply a more lasting cells contact in microgravity and a broader horizontal transport of genetic material. SFF had no effect on recombination frequency and mutation in a model of parental auxotrophic markers reversion to prototrophism. It was demonstrated that SFF boosted the fC31 phage exit from S. lividans 66 (fC31) and did not influence phage induction in S. coelicolor A3(2) (fC31). SFF inhibited synthesis of antiobiotic actinorhodin in lisogenic S. coelicolor A3(2), and tylosin and desmicosin in S. fradiae. Survivability of electrogenic bacteria Shewanella oneidensis MR-1 in space flight was higher compared with the synchronous control experiment. The reduction activity of S. oneidensis MR-1 as an indicator of electron generation effectiveness was identical in flight and laboratory samples.

[Microbial fuel cells as an alternative power supply].

Purpose of the work was designing and prototyping of microbial fuel cells (MFC) and comparative evaluation of the electrogenic activity of wastewater autochthonous microorganisms as well as bacterial monocultures. Objects were model electrogenic strain Shewanella oneidensis MR-1, and an Ochrobactrum sp. strain isolated from the active anode biofilm of MFC composed as an electricity generating system. The study employed the methods typically used for aerobic and anaerobic strains, current measurement, identification of new electrogenic strains in microbial association of wastewater sludge and species definition by rRNA 16-S. As a result, two MFCs prototypes were tried out. Besides, it was shown that electrogenic activity of S. oneidensis MR-1 and Ochrobactrum sp. monocultures is similar but differs from that of the microbial association of the anode biofilm.

[Testing of the gas vortex culture stirrer under conditions of short-term microgravity].

Functional testing of the bioreactor for stirring culture in microgravity was performed during the microgravity episodes aboard research airplane Il-76 following the Kepler parabolic flight path. The attempt to produce the gas vortex stirring effect in a given liquid volume was a failure. Nonetheless, the stirrer ventilator is capable to agitate liquid acting as a mechanical stirrer.
