Danichenko M. Y., Melnik О. V., Mikheev A. A., Solomakha V. N., Shuvalov P. L. Estimation of synchronization in functioning of the cardiovascular and respiratory systems of the body

 

Parallel processing of rhythmocardiogram and pneumatogram provides information about the synchronizing degree of cardiovascular and respiratory systems and more significantly, compared to the analysis of only the parameters of heart rate, identify the dominant mechanism of physiological processes regulation. A study of various methods of forming cross-correlation criteria in temporal and spectral domains was conducted; the sources of modeling errors was analyzed and recommendations for the optimal choice of the methodology of rhythmocardiogram and pneumatogram synchronization control for the «home diagnostics» class of diagnostic system was proposed.

 

Keywords: adaptive capacity, Fechner coefficient, cardiointervalogram, correlation coefficient, correlation relation, methodical error, pneumatogram, synchronization, functional status.

Basic approaches to on-line monitoring of hemodialysis are considered. A novel bispectral method and a system for monitoring of uric acid concentration in effluent dialyzate in the outlet of a dialysis machine are described. The system consists of the optoelectronic bispectral sensor based on ultraviolet light emitting diodes and special software. The results of the clinical trials of the system and future perspectives of its applications in medicine and related fields are analyzed.

 

Keywords: hemodialysis, monitoring, ultraviolet spectrophotometry, chronic renal failure.

Korolev D. V., Uskov I. S., Sonin D. L., Grigirova Yu. N., Galagudza M. M., Postnov V. N., Naumisheva E. В. Acute toxicity, biodistribution and bioelimination of organo-silica nanoparticles

 

The study was aimed at investigation of acute toxicity, biodistribution, and bioelimination of organosilica nanoparticles. We were interested to explore the potential of this type of nanocarrier for delivering drugs specifically into the area affected by the disease. For that purpose, the nanoparticles of 3D-linked organosilica with the average diameter of 3.8 nm were synthesized. Intravenous administration of nanoparticles was not associated with acute toxicity. It was shown that organosilica nanoparticles were rapidly eliminated from the organism via the filtration through glomerular filter.

 

Keywords: biodistribution, bioelimination, nanoparticles, organosilica, synthesis, toxicity.

Medical and Technical Management and Education

Tolmachev I. V., Ripp E. G., Tropin S. V., Karpushki-na E. V., Tsverova A. S. «Anaphylactic shock» the development and realization of clinical scenarios in an artificial environment

Simulation training is a learning process in which the learner performs actions in an environment simulating real, using specific simulators, simulators, phantoms, dummies and robots consciously. Simulators are controlled by computer software and experts in the classroom or in the next room. Such training can imitate a variety of clinical conditions due to the physiological parameters that can be simulated ECG, blood pressure, blood oxygen saturation, pulmonary arterial pressure, intracranial pressure, body temperature.

Designed scenario «anaphylactic shock» include sections: the main problem, study habits, a brief description, dummy preparation for simulation, training office for simulation, consumables, scenario description, description of the simulation, the information for the operator, the outcome training, commissioning scenario, the algorithm of correct actions of students, the main topic of debriefing.
