To study the characteristics of the spread of the COVID-19 pandemic and introduce timely and effective measures, there is a need for models that can predict the impact of various restrictive factors on COVID-19 disease dynamics. In this regard, it seems expedient to employ agent-based models that...

Previous studies have shown that intraoperative optical diagnostics can be used to solve fundamental and applied problems in gynecology. Our article presents results from experimental in vivo intraoperative measurements of endogenous fluorescence and blood perfusion in various sections of the...

The study employs laser doppler flowmetry and laser fluorescence spectroscopy to reveal the changes in microcirculation and activity of coenzymes of oxidative metabolism in the finger skin under the influence of photobiostimulation by monochrome incoherent low-intensity electromagnetic radiation...

This work demonstrates some results of the successful experience of using wearable devices for multimodal optical diagnostics of microcirculatory-tissue systems both in clinical practice and in the conditions of a Space experiment. The multimodal approach based on simultaneously applying a minimum...

Age-related macular degeneration (AMD) is one of the leading causes of irreversible blindness. Every year, there is an increase in the number of patients with AMD worldwide. To date, the primary method in diagnosing AMD is optical coherence tomography (OCT), which provides the most visual data for...

The use of automated and robotic systems for precision low-traumatic surgery is a common trend in modern medicine. One of the promising tools for such operations is an automated laser scalpel based on a scanner with real-time diagnostics of the process of biotissue evaporation. The paper...

Phototherapy is widely used for neonatal hyperbilirubinemia treatment; however, the most important but not completely recognized issue is the determination of the optimal spectral range of light that provides an effective reduction of bilirubin level in the blood of a newborn with minimal adverse...

Biotechnology is playing an extremely important part in medical advances. In actuality, they are the basis of pathology diagnosis, which provides doctors with the quantitative data required to choose the best treatment. This study looks at the facts of a case of weak muscular activity and devises...

In the recent years promising results have been shown by the use of Compression optical coherence elastography (C-OCE) as a new optical biopsy approach to morphological assessment/diagnostics of human breast cancer using differences in elastic properties of morphological components of cancerous...

The possibility of hair bonding by continuous laser radiation with a wavelength of 980 nm has been studied. A computer optical model of a laser system for bonding of human hair has been created. Using the Monte Carlo method, the distribution of the power of the absorbed laser radiation in the...

There are many cases in the medical laboratory examinations when it is necessary to detect a vein in a patient and the blood vessels are not visible to the naked eye. In such situations, devices for optical vein visualization are required. Nowadays, the technology of optical vein visualization is...

This paper is devoted to the application of mathematical methods of classification and differentiation of low-resolution spectral data arrays of Raman light scattering for complex biological compounds as human platelets. Spectral data arrays consisted of 1266 spectra from 4 groups of patients,...

Multiphoton microscopy and especially two-photon microscopy are actively used in dermatology for the diagnosis and analysis of skin diseases. The typical skin probing depth for these methods is limited to 150–200 μm due to the strong scattering properties of skin. The application of the optical...

A comparative analysis of methods for processing and classification of medical images was exemplified by neutrophil nuclei digital images. Special consideration was given to three methods: 1) measuring the fractal dimension of neutrophil nuclei to determine their functional state; 2) selecting the...

The problem of measuring the fraction of weakly deformable erythrocytes in a blood sample by the laser diffractometry in a shear flow (ektacytometry) is considered. The algorithm for measuring this parameter is proposed, based on a comparison of experimentally observed diffraction patterns with...

Conventional imaging practices used for the inspection and monitoring of biological specimens employ RGB cameras with limited capabilities for early identification of diseases or abnormalities. In this work, we demonstrate and validate a quick, non-destructive, and precise inspection method...

Diabetic ketoacidosis (DKA) is a serious complication arising due to the shortage of insulin that allows blood sugar into cells to be used as energy. As a result, the liver begins to break down fat for energy, thus producing acids called ketones. The severity of DKA influences the number of ketones ...

Decent lighting is a major requisite in Laparoscopic and Endoscopic examinations, as the illumination is below the edge value, the image becomes distorted resulting inaccurate outcome. Double perovskites with flexible formulas and structures, lithic chemical-physical properties, and suitable...

In this study terahertz (THz) absorption spectra of mouse blood serum in the dynamics of experimental U87 glioblastoma were investigated. Decrease of THz absorption with glioma growth was demonstrated. A two-component Debye model was used to analyze the experimental data. Analysis of the complex...

Salivary sensors are ideal non-invasive diagnostic platforms for cancer detection owing to the existence of many proteins and metabolites that can reflect individual’s health status. Elevated levels of thiocyanate (SCN−) in smokers’ saliva may be a potential biomarker indicating increased oral...
