  • 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.

    • Authors: A. S. Tomskikh; M. V. Bochkarev; E. S. Yakushenko; V. G. Gumennyi; L. S. Korostovtseva; Yu. V. Sviryaev
      Abstract: An automated algorithm for identifying periods of sleep and waking using data from the motor activity of the subject’s thoracic cage is proposed. The algorithm is based on accelerometry and is intended as a component of systems used for prolonged monitoring of cardiovascular system functions. 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.

  • Correction of Immunoendocrine Disorders in Patients with Ischemic Heart
           Disease Using Low-intensity Microwave Therapy
    • Authors: A. V. Logatkina; V. S. Nikiforov; S. S. Bondar; I. V. Terekhov
      Abstract: The article considers the possibility of correcting immunoendocrine disorders in patients with ischemic heart disease using low-intensity microwave radiation at a frequency of 1 GHz. The study showed that the Aquaton device for low-intensity microwave therapy could be used to stimulate production of bradykinin, NO, IL-24, antioxidants, and soluble tumor necrosis factor-alpha receptor II by whole blood cells. Exposure to microwave irradiation was accompanied by a decrease in the caspase-1 content in mononuclear leukocytes with a simultaneous increase in the nuclear transcription factor NFκB level, promoting thereby normalization of the subclinical inflammatory process and correction of endothelial dysfunction.

    • Authors: A. F. Bobrikhin; A. G. Gudkov; D. I. Tsyganov; S. V. Agasieva; E. N. Gorlacheva; V. Yu. Leushin; V. D. Shashurin
      Abstract: Cryosurgery has such advantages as easy implementation, painlessness, high accuracy, low recurrence rate, and lasting cosmetic effect. However, application of liquid nitrogen as a spray or using a cotton swab does not provide cryonecrosis of pathological tissues. The required cooling rate can be obtained using special cryogenic devices. The KM-01 and KM-02 devices are designed for removal of pathologically changed tissues by exposure to liquid nitrogen. The KM-01 device is used for contact cryodestruction. It is implemented as a container for liquid nitrogen coated with thermal insulator. A cannula at the bottom of the container allows replaceable metal tips of various shapes and sizes to be attached to the container. The KM-02 device can be used for both contact and contactless cryodestruction. To provide surgery at poorly accessible areas, the device was made compatible with a large range of tips of complicated shapes, as well as rigid and flexible tubes of various lengths. During contact surgery, both the tip and the skin area in direct contact with the tip are cooled, while in contactless surgery only the skin area is cooled by spraying. The areas of application of the devices include dermatology, cosmetology, dentistry, oncology, surgery, gynecology, and otolaryngology.

  • An Automated Method for Segmenting Brain Tumors on MRI Images
    • Authors: A. R. Abdulraqeb; W. A. Al-Haidri; L. T. Sushkova; M. M. Abounassif; P. J. Parameaswari; M. A. Muteb
      Abstract: We present a method for segmenting images of tumors on MRI images of the brain based on an algorithm developed for automated determination of segmentation and outlining thresholds. Testing was performed by generating two databases of real MRI images of the brain, with radiology reports. Criteria for assessment of the quality of the segmentation results were: the Dice score, the Jaccard index, sensitivity, and specificity. Analysis of results obtained using this algorithm to solve the brain tumor MRI image segmentation task showed levels of sensitivity and specificity of 89% to 99%, which is evidence that assessment of the position and boundaries of brain pathology is highly effective.

    • Authors: E. O. Filippova; N. S. Calanda; V. F. Pichugin; A. N. Aleinik; A. M. Guriev; M. V. Belousov
      Abstract: Currently, much attention is paid to low-temperature atmospheric-pressure plasma as an agent for gentle antimicrobial decontamination. In this work, data on the efficiency of low-temperature plasma for antimicrobial decontamination of polyethylene terephthalate track membranes used as corneal implants in keratoplasty are presented. The obtained results show that 30-, 60-, and 90-s exposure to low-temperature plasma has a gentle decontaminating effect on track membranes.

  • A Model Hand Prosthesis Controlled by Foot and Toe Movements
    • Authors: E. I. Vorob’ev; A. V. Mikheev; K. O. Morgunenko
      Abstract: An approach to controlling hand prostheses using foot and toe movements is proposed. Construction of a model hand prosthesis with independent finger movements is described. A wireless remote control system for the prosthesis by tactile insoles fitted into the shoes is presented. Transfer parameters are selected by a synthesis based on the required final foot positions in the input and output sides of the system. Pneumatic bellows parameters, bracing spring stiffness, and pressure in the pneumatic circuit are selected on the basis of size restrictions and forces on the fingers. The study was supported by the Russian Foundation for Basic Research (Grant No. 16-08-00305A).

           Transcutaneous Power Transfer to Implanted Medical Devices
    • Authors: A. A. Danilov; E. A. Mindubaev; S. V. Selishchev
      Abstract: The problem of variation of the output characteristics (voltage, current, power) of inductive powering systems for implantable medical devices is considered. The variation is primarily caused by relative misalignment of transmitting and receiving coils. A classification of misalignments is proposed. Main approaches to coil misalignment compensation are: mechanical fixation of the coils; evaluation of the relative position of the coils for elimination of misalignment or further tuning of the transmitting part of the system; optimization of the coil geometry providing stability within the given misalignment range; tuning the working frequency of the transmitting part of the system. It is shown that the compensation method should be selected with due regard to the implantable device parameters (first of all, the coil implantation site and the power consumption of the device).

  • A Device and a Method for Determining the Rate of Oxygen Consumption by an
           Isolated Perfused Rat Liver
    • Authors: K. V. Shadrin; V. G. Pakhomova; O. V. Kryukova; A. P. Rupenko
      Abstract: The goal of this work was to suggest a method for measuring the total rate of oxygen consumption by an isolated perfused rat liver. This method involves calculation of the rates of oxygen consumption by the blood stream and through the liver surface. The two independently determined values are then summed up to determine the total consumption rate. Experimental results obtained by this method are in good agreement with the results obtained previously using the manometric method of measurement of the oxygen consumption rate.

  • A Method for Investigation of the Acoustic Reflex on the Basis of
           Impedance Measurements
    • Authors: S. P. Dragan; A. V. Bogomolov; A. D. Kotlyar-Shapirov; E. A. Kondrat’eva
      Abstract: A method for investigation of the acoustic reflex on the basis of impedance measurements was suggested. The method involves evaluation of the tympanic membrane response to sound stimulation by measuring the acoustic impedance of the external auditory canal. The capabilities of the method were assessed both by physical modeling using a Helmholtz resonator and by a full-scale study in volunteer subjects.
