Sports-related traumatic brain injuries (TBI) accounts for up to 20 % of all injuries that are obtained by athletes and its incidence rises annually due to rise in population involving in sports, growing popularity of extreme sports and high level of motivation to achieve record results among young sportsmen. The aim of the review is to present the potential benefits of using microwave radiothermometry and craniocerebral hypothermia technologies in sports-related TBI. The review considers most common form of traumatic brain injury in athletes - mild TBI, which in turn can provoke a wide range of complications and negative consequences in near and delayed periods after the injury. The main shortcomings of programs for complication prevention in treatment and rehabilitation of athletes after TBI are considered, which do not take into account the peculiarities of injury mechanisms, its significant differences from household, road or criminal injuries with brain damage. Lack of objective methods of instrumental diagnosis for injury severity is also described. In addition, pathophysiological component characteristics of sports TBI is accentuated: frequency of repetition, increasement of brain and body temperature, peripheral redistribution of blood flow and hypocapnia, which significantly affects cerebral blood flow. Based on the analysis of the available scientific literature, it is elicited that TBI is an independent cause of cerebral hyperthermia development, which significantly aggravates the consequences of the injury. Conclusions. The authors propose an innovative way to use microwave radiothermometry method as a diagnostic tool for sports-related TBI. In addition, the review highlights the main recommendations for complications prevention by using craniocerebral hypothermia technology, which reduces overall physical and cerebral hyperthermia, and augments the resistance of cerebral cortex neurons to hypoxia and trauma. However, the authors believe that the described approaches in sports medicine are not used purposefully due to lack of awareness of sports team doctors and coaches.

“…We can use this method to construct vector 3D models of samples that are necessary for theoretical modeling physical processes in highly heterogeneous biological tissues [18,21]. Such 3D models allow to take into account the fine structure of real tissues and changes in their physical parameters.…”

Abstract.A software for processing sets of full-color images of biological tissue histological sections is developed. We used histological sections obtained by the method of high-precision layer-by-layer grinding of frozen biological tissues. The software allows restoring the image of the tissue for an arbitrary cross-section of the tissue sample. Thus, our method is designed to create a full-color 3D reconstruction of the biological tissue structure. The resolution of 3D reconstruction is determined by the quality of the initial histological sections. The newly developed technology available to us provides a resolution of up to 5 -10 µm in three dimensions.

Abstract. The microwave thermometry method for the diagnosis of breast cancer is based on an analysis of the internal temperature distribution.This paper is devoted to the construction of a mathematical model for increasing the accuracy of measuring the internal temperature of mammary glands, which are regarded as a complex combination of several components, such as fat tissue, muscle tissue, milk lobules, skin, blood flows, tumor tissue. Each of these biocomponents is determined by its own set of physical parameters. Our numerical model is designed to calculate the spatial distributions of the electric microwave field and the temperature inside the biological tissue. We compare the numerical simulations results to the real medical measurements of the internal temperature.
