Abstract Biomineralization of brain tissues occurs both in normal and pathological conditions. Dura mater biomineralization is widespread 1–72% cases, depending on the patient's age research method. The amount biomineral deposits under conditions tumor growth meninges only increases, reaching 100% case psammomatous meningiomas. Since calcifications are often found meninges, problem differential diagnosis with calcified meningiomas arises. A total 30 samples signs biomineralization—dense...
The detection of microcalcifications in the breast by mammography is great importance for early diagnostics cancer. This study aimed to establish basic morphological and crystal-chemical properties microscopic calcifications their impact on cancer tissue. During retrospective study, 55 out 469 samples had microcalcifications. expression estrogen progesterone receptors Her2-neu showed no significant difference from non-calcified samples. An in-depth 60 tumor revealed a higher osteopontin...
The study of the structure-phase composition and electrophysical properties film alloys molybdenum nickel or iron were deposited by method simultaneous thermo-vacuum condensation was done.In a non-annealing state, samples remain biphasic.After heat treatment at 750 K in vacuum, formation metastable phases fcc-Ni3Mo (lattice parameter 0.360 nm) bcc-Fe2Mo (a 0.296 based on Ni Mo recorded concentrations atoms ferromagnetic metal 75 65 at.%respectively Investigation thermoresistive films...
The analysis of curves the dependence thermal destruction rate vs. temperature at heating (thermogram) whole samples and fragments ostrich (Struthio camelus) eggshell was carried out. It shown that complex character thermograms is mainly due to difference in individual morphological components eggshell. comparative contribution each micro-nanostructural (mamillary, palisade, crystalline layers) integral yield carbon dioxide (CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Psammoma Bodies (PBs) are concentric calcined structures. The formation of PBs begins during the initial stages carcinogenesis, which is an important feature for diagnostics serous ovarian carcinoma. aim our work was to study nanocrystalline structure carcinoma practical use in diagnostics. According size, these structures were divided into 3 groups: large - more than <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{200}\...
This paper is devoted to morphology, microstructure, phase and elemental composition of pathological crystalline inclusions in malignant ovarian neoplasms. It was found that minerals are represented by calcium apatite with different levels crystallinity. The transmission electron microscopy combination microdiffraction has shown some structural morphological features crystals, which were not detected other methods. According microscopy, the particles calcifications polydisperse (of sizes)...
In the metal structures that are subjected to significant mechanical and radiation loads during their operation, structural alterations occur, which unevenly distributed over depth of material.Materials with a modified surface, including thin coatings multilayers, equally challenging objects for studies.The development methods depth-selective layer-by-layer X-ray diffraction diagnostics is nontrivial task aimed at controlling effective collection information.The most developed approaches...
This paper focuses on the morphology and chemical composition of gallbladder calcifications. Our study involved examination 25 samples, comprising 5 cases porcelain (PG), 10 samples cholelithiasis (ChL), cancer (GC) with biomineralization. The use alizarin red staining confirmed presence calcium compounds in calcified tissues wall, as indicated by orange-red coloration. Furthermore, von Cossa revealed that all wall calcifications contained phosphate compounds. findings demonstrate different...
This article describes the details of a new complex method producing calcium carbonate nanoparticles intended for its use in industrial poultry industry as biocidal component nanocomposites coating hatching eggs.

This paper is devoted to the morphology and elemental composition of breast cancer calcification. By histology, it we verified that all 30 selected samples had a signs biomineralization. These calcified formations dark blue color, variable size round irregular shapes. Von Cossa staining confirmed presence calcium phosphate in their composition. We have shown by SEM TEM mineral deposits correspond nanocrystalline apatite. According TEM, crystalline nanoparticles were polydisperse (of...
