  • Assessment of Transcapillary Water Exchange in the Lungs by Active
    • Authors: S. S. Bondar; I. V. Terekhov; A. A. Voevodin; B. I. Leonov; A. A. Khadartsev
      Abstract: The possibility of noninvasive assessment of transcapillary water exchange in the lungs using stimulated microwave emission of the chest organs is discussed. The results of the study showed that the distribution of 1 GHz microwave emission of tissues probed using low-intensity electromagnetic waves at 65 GHz corresponded to the distribution of pulmonary blood flow. Calculations showed that the intensity of transcapillary water exchange in the lungs was distributed exponentially from the apices to the basal parts of the lungs. The distribution of the transcapillary water exchange was shown to vary according to the pulmonary perfusion gradient, which is indicative of a correlation between the parameters of pulmonary perfusion and the intensity of stimulated microwave emission of tissues at the frequency of 1 GHz. This correlation can be used for noninvasive assessment of pulmonary perfusion by active radiometry.

  • Multiresolution Analysis of ECG Signals in Heart Rhythm Monitoring
    • Authors: A. A. Fedotov
      Abstract: The paper is devoted to multiresolution analysis of ECG signals in heart rhythm monitoring. The proposed method for R-wave detection in ECG signals is based on extracting detail coefficients from the wavelet decomposition of the ECG signal. It uses nonlinear transforms and the adaptive threshold algorithm. The suggested approach is compared to existing methods for R-wave detection in ECG signals used for processing clinical ECG records from the MIT Physionet database.

    • Authors: N. N. Sarbaeva; M. N. Milyakova; V. V. Rossinskaya; O. V. Gribkova; D. A. Dolgushkin
      Abstract: Acellular dermal matrixes (ADM) for reconstructive surgery were made by treating skin samples from rats and humans with sodium dodecylsulfate (SDS), sodium deoxycholate (DOC), saponin, and DNase. A mixture of SDS and DOC removed cell residues effectively, though the ADM had cytotoxic properties. After treatment with 2% DOC, there was no cytotoxic effect and the resulting material contained 27-202 ng/mg dry weight DNA and from 0.07 to 2.6% fat, depending on the source of the samples.

  • Current Medical and Technical Concepts in the Analysis of Endocardial
           Signals in Atrial Fibrillation
    • Authors: A. P. Zaretskiy; A. P. Kuleshov; G. A. Gromyko
      Abstract: Atrial fibrillation (AF) is the commonest arrhythmia seen in clinical practice, though our understanding of the mechanisms of its generation, propagation, and reinitiation remains incomplete. This is limiting not only from the scientific point of view, but also from the practical, as regulatory documentation for the treatment of this pathology cannot be developed without an accepted theory. There has been a recent increase in interest in a theory based on the observation that spiral waves, or rotors, with specific properties for each atrium, are the source of the trigger for fibrillation and may therefore serve as targets for radio-frequency treatment in low-invasive endocardial procedures. There is also an approach based in seeking areas of the atrium in which complex fractionated atrial endograms (CFAE) can be recorded. We present here the basic concepts of analysis of atrial signals during atrial fibrillation, reflecting both the technical and medical aspects.

  • Analytical Identification of Isolated Clustered Microcalcifications Based
           on the Distribution of Effective Atomic Numbers
    • Authors: V. A. Gorshkov; N. I. Rozhkova; S. P. Prokopenko
      Abstract: The goal of this work was to improve the efficiency of early detection of microcalcifications, the earliest indicators of breast cancer. Studies have shown that the presence of isolated clustered microcalcifications in the mammary gland significantly increases the range of variation of effective atomic number and considerably changes its distribution. Conventional, subtraction, or dividing mammography or their linear convex combination may fail to visualize isolated clustered microcalcifications. However, the presence of microcalcifications in the mammary gland can be determined analytically from the distribution of the extreme terms of an ordered series of effective atomic numbers in the mammary gland. Then, the coordinates of the isolated clustered microcalcifications can be calculated. The distribution of the effective atomic numbers in healthy tissue without microcalcifications is symmetric and close to normal, while breast tissue with even a single isolated cluster of microcalcifications is characterized by an asymmetric distribution and high values of the maximum effective atomic numbers. An algorithm for calculating the coordinates of isolated microcalcifications is suggested.

  • A Perfusion Bioreactor for Making Tissue-Engineered Constructs
    • Abstract: Experiments were performed to develop a design for a flow bioreactor. A system was constructed consisting of a small-scale bioreactor placed in a CO2 incubator, with four chambers for making tissue-engineered constructs, providing for long-term experiments in flow conditions maintaining sterility with different humidity and temperature factors in the culture and gaseous media. The adverse influences of flow on cell viability were minimized by optimizing the culture medium flow rate and the excess pressure in the flow chambers. The functional effectiveness of the bioreactor was demonstrated by chondrogenic differentiation of cells in a cell-engineered construct consisting of a microheterogeneous collagen-containing hydrogel matrix biopolymer, mesenchymal stromal cells from human fatty tissue, and chondrogenic differentiation medium as an example.

  • In vivo Osteogenerating Properties of Calcium Phosphate Coatings on
           Ti-6Al-4V Titanium Alloy
    • Authors: S. V. Gnedenkov; S. L. Sinebryukhov; A. V. Puz’; R. E. Kostiv
      Abstract: The task of developing means of forming biocoatings improving the characteristics of metal implant bases remains important and current in contemporary implantology. Creation of bioactive layers with high levels of compatibility with bone tissue on implant surfaces is beneficial for better adaptation of the body to the implant. Introduction of such coatings, lacking adverse (toxic) actions, into the living body should strengthen osteointegration with bone tissue and stimulate regeneration processes. Bioactive calcium phosphate layers are of particular interest, as these contain calcium phosphate, which is “native” to bone tissue. Studies in this direction will lead to the development of a new method in medicine − bone tissue engineering. A means of forming a calcium phosphate coating on the medical titanium alloy BT6 (Ti containing 3.5-5.3% by weight V, 5.3-6.8% Al) by plasma electrolytic oxidation (PEO) was developed. The calcium phosphate coating was obtained in a bipolar PEO regime in a glycerophosphate-containing electrolyte. The osteogenerating properties of the coating were assessed in fractures of the diaphyseal part of the femur in Wistar lab rats. The calcium phosphate PEO coating was found to accelerate osteogenesis and promoted the formation of good periosteal callus at the fracture site.

Use of this algorithm allows trace segments to be defined as “sleep” or “waking” with accuracies of up to 77.6% in the overall cohort, 83.7% when there are no sleep disorders, and 70.5% in patients with respiratory abnormalities during sleep. Use of the algorithm in Holter monitoring systems in routine practice will help improve the accuracy of diagnostic results in cardiovascular diseases and the detection of sleep disorders.

  • A Study of Mechanical Properties of Vascular Prostheses under Different
           External Conditions
    • Authors: G. V. Savrasov; N. V. Belikov; I. V. Khaydukova
      Abstract: Biomechanical properties of vascular prostheses measured under different experimental conditions were compared. Strength and viscoelastic tests were conducted both under normal conditions (in air, at room temperature) and under conditions close to the internal environment of human body (in saline, at 37°C). There was a statistically significant difference between the results of measurement of the elastic hysteresis and the Young’s modulus (measured in the linear elastic region) under the two types of conditions. The obtained results prove the necessity of testing the mechanical characteristics under quasi-in vivo conditions. The testing method suggested in this work can be used for this purpose.
