A new promising method for preliminary ion beam processing of titanium implants has been suggested and tested. The method uses high-energy Не⁺ ion implantation to achieve a high level of open porosity needed to form thin-layered coatings by the method of gas-thermal oxidation in air. The mechanism of pore formation and the effect of the obtained structurally heterogeneous oxide coatings on the osteointegration of rod implants are described.

The optoacoustic effect leading to excitation of acoustic waves upon absorption of a variable light flux is considered. This effect is of interest from the viewpoint of practical application in biomedical measurements as a promising noninvasive method for diagnostics of biological objects. The results of experimental flow diagnostics based on laser excitation of an optoacoustic signal in liquid are presented. An algorithm of the flow cytometry procedure is developed.

Computation of the temperature regime of a thermoelectric neonatology system is considered. Differential equations are used to provide the basis for computational relationships describing convective heat exchange in the system. Laminated thermoelectric batteries are calculated and optimized to form a specified distribution of temperatures in the neonatology resuscitation system. The optimized characteristics of the laminated thermal element are presented.

The paper presents the results of calculation of temperature fields of rotating anodes of powerful X-ray tubes. An overview of the basic properties of the anode materials is also presented.

We present here a method for computerized processing of electrocardiograms providing for averaging of the electrocardiogram signals over prolonged periods. The results of a comparative evaluation of the variability of the amplitude and time parameters of conventional and averaged electrocardiography are presented. Averaged electrocardiography is shown to have advantages over conventional methods of processing the electrocardiogram signals for personalized monitoring of electrocardiographic changes due to its higher reproducibility.

This article describes a method for forming daily blood glucose (BG) tracks for diabetes mellitus patients using protocols taken from the DirecNet database. The obtained daily tracks can be used for testing mathematical models of BG regulation, verifying BG prediction algorithms, and analyzing individual trends in patient’s BG dynamics.

The effect of patient’s individual characteristics on the output of wireless transcutaneous inductive energy transfer systems has been studied. Numerical modeling shows that small changes in the implantation depth due to patients’ individual characteristics (thickness of skin, subcutaneous fat layer, and bones) can lead to significant changes in output power and efficiency of the energy transfer. Our study shows that the effect of these changes can be compensated by optimizing the size of the external (transmitter) coil.

The classification of the stages of genital herpes is discussed on the basis of readings from acupuncture points P7 and VC7, which change their energy characteristics as the activity of genital herpes increases. Inclusion of reflex therapy methods to traditional treatment schemes was found to promote decreases in the duration of clinical episodes. A scheme for a standalone instrument based on a microcontroller with low energy consumption able to monitor the energy status of acupuncture points is described.

A new direction in magnetotherapy has developed in recent years, particularly in Russia, on the basis of Russian-manufactured magnetotherapy instruments of the “Magnitoturbotron” type; in this approach, the whole body is exposed to weak low-frequency vortex magnetic fields (VMF). One systemwide VMF magnetotherapy approach is the introduction of this treatment to regimens for the radial and restorative treatment of oncological diseases. In this regard, the effective use of weak low-frequency VMF on the patient’s body requires deeper study of both the local effects of treatment on tumors, but also the systemic reactions of the body as a whole.
