This article provides a brief overview of silymarin extract from milk thistle. It also discusses the issue of Silymarin extraction and solutions for effective Silymarin extraction.

Протонная магнитно-резонансная спектроскопия позволяет определить изменения метаболических процессов в тканях головного мозга при различных заболеваниях центральной нервной системы. Однако следует отметить, что диагностические возможности протонной магнитно-резонансной спектроскопии зависят от...

Обнаружение и ограничение по контуру отдельных клеток на цифровых микрофотографиях является наиболее сложным шагом в цитомерии, при автоматизации которого используются различные методы, позволяющие установить корректный диагноз. Цель исследования. Определить наиболее часто встречающиеся в научной...

This article presents a developed two-stage method for decomposing a spectral contour with a high degree of overlap of Raman scattering (RS) lines. The algorithm allows you to take into account the error in the position of the Raman bands and other parameters, and work with asymmetric lines. By...

Optimizing the analysis of radiographs of temporomandibular joint (TMJ) bone structures taken with cone beam computed tomography (CBCT) is an important topic in modern dentistry. The aim of the study is to establish stable correlations between the cranial indices obtained by cone-beam computed...

This paper presents a technique for selecting regions of interest in retinal angio-OCT images to quantitatively analyze choroidea parameters in order to detect ocular diseases. The significance of this research lies in the fact that choroideas are an important part of the eye responsible for...

The aim of this work is to identify drusen subtypes on OCT images for the diagnosis of age-related macular degeneration. In this paper we propose a technology of drusen extraction on OCT-images and their classification. The relevance of the problem is determined by a large number of age-related...

Skin imaging with optical methods is always limited in depth mainly due to the strong scattering of the excitation and emission light, which significantly reduces the contrast of the images and the probing depth. One of the reasons for the scattering is the mismatch in refractive indices between...

We consider the issues of obtaining information about the distribution of red blood cells in size from the scattering pattern of a laser beam on a wet blood smear. Within this article it is assumed to calculate the first three moments of the size distribution. The analytical model of light...

In this study we have analyzed the change in the intensity distribution of three-wavelength transillumination images of human interphalangeal joints under the action of the optical clearing agent. RheumaSens medical scanner prototype with the following wavelengths: 660, 850, and 905 nm, has been...

Nickel-titanium (NiTi) implants take root well in the body and have high biocompatibility with respect to surrounding tissues. Porosity is an important parameter responsible for the biocompatibility of the material, and as a result, it is important to be able to control the material manufacturing...

The acousto-optic (AO) effect, characterized by the deflection and modulation of photons by ultrasound, is currently being explored to a certain degree. AO could bring together advantages of optics and acoustics particularly addressing the challenges of spatially accurate deep tissue optical...

Compact sapphire capillary needles for laser-assisted therapy connected to optical fibers by the means of internal channel closed from one side transmit laser radiation to the tissues with minimal loss of energy and simultaneously protect the fibers. The geometry of the internal capillary channel...

In healthcare settings, particularly for newborns in the Neonatal Intensive Care Unit (NICU), continuous and accurate monitoring of respiratory rates (RR) is crucial, yet current methods often involve manual region selection, which limits their effectiveness. To address this challenge, we developed ...

Dual-wavelength photodynamic therapy (PDT) in combination with fluoescence monitoring has great potential in medical applications, in particular, in the treatment of skin diseases. In this study we conducted numerical Monte Carlo experiments in a two-layer skin model to simulate the absorbed light...

The high sensitivity of Raman spectroscopy to the chemical composition of substances at the molecular level makes it a valuable tool for the diagnosis of chronic heart failure (CHF) through analysis of blood serum. Raman spectroscopy offers a label-free, fast detection method, with highly specific...

The subject of this article which is the second part of the review published earlier, is the methods of fluoresce microscopy which make it possible to avoid the diffraction restrictions and obtain image resolution with sub-diffraction accuracy. These methods provide new opportunities for biomedical ...

Aqueous suspensions of nanocontainers consisting of porous silicon (PSi) nanoparticles with Methylene blue (MB) loading were investigated by means of the optical spectroscopy and infrared thermometry under laser irradiation. The photothermal conversion efficiency and kinetics of the MB release from ...
