Проанализировать топографические сценарии формирования кальцифика-тов в дисфункциональных аортальных клапанах сердца и атеросклеротических бляшках.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Дисфункциональные аортальные клапаны сердца (n = 18) и атеросклеротические бляшки (n = 20) фиксировали в формалине, постфиксировали в 1% тетраоксиде осмия, последовательно окрашивали 2% тетраоксидом осмия и 2% ура-нилацетатом и заключали в эпоксидную смолу Epon с последующей шлифовкой и полировкой сформованных блоков. После контрастирования цитратом свинца и напыления углеродом проводили визуализацию образцов методом сканирующей электронной микроскопии в обратно рассеянных электронах и элементный анализ кальцификатов методом энергодисперсионной рентгеновской спектроскопии. Измерение соотношения Ca/P в кальцификатах аортальных клапанов и бляшек произведено по схеме «бильярдного стола» в центре кальцификата и часовой стрелке в ближней и дальней окружностях, а также в контрольных участках возле и вдали от кальцификата. Топографические сценарии формирования кальцификатов моделировали при помощи корреляционного анализа.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлена значимая корреляция соотношения Ca/P в центре кальцификата с таковой в ближней и дальней окружностях как в клапанных (г = 0,35-0,78 в ближней окружности; г = 0,63-0,69 в дальней окружности), так и атеросклеротических (г = 0,37-0,56 в ближней окружности; г = 0,48-0,63 в дальней окружности) кальцификатах, что свидетельствует об иерархическом принципе формирования очагов кальцификации.</p></sec><sec><title>Заключение</title><p>Заключение.

To analyze the topographic patterns of valvular and atherosclerotic calcification growth.</p></sec><sec><title>Methods</title><p>Methods.           Dysfunctional aortic valves (n = 18) and atherosclerotic plaques (n = 20) were fixed in formalin, postfixed in 1% osmium tetroxide, consecutively stained by 2% osmium tetroxide and 2% uranyl acetate, and embedded into epoxy resin (Epon) with the further grinding and polishing ofthe samples. Upon the counterstaining by lead citrate and sputter coating with carbon, samples were visualized by backscattered scanning electron microscopy. Elemental analysis was conducted via energy-dispersive X-ray spectroscopy. Measurement of Ca/P ratio within the mineral deposits was carried out employing a pool table principle (i.e., in the center of the deposit, in the near and far circumferences (clockwise), and in control regions around the mineral deposit). Topographic patterns of calcifications were modeled using the correlation analysis.             </p></sec><sec><title>Results</title><p>Results. Significant correlation was revealed between the Ca/P ratio in the deposit center and in the near and far circumferences of deposit in both in valvular (r = 0,35-0,78 - near circumference; r = 0,63-0,69 - far circumference) and atherosclerotic mineral deposits (r = 0,37-0,56 - near circumference; r = 0,48-0,63 - far circumference), suggesting the hierarchical growth of cardiovascular calcification around the initial nucleation sites.</p></sec><sec><title>Conclusion</title><p>Conclusion.       Valvular and atherosclerotic calcifications development is concentric.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>атеросклероз</kwd><kwd>кальцинирующий аортальный стеноз</kwd><kwd>минерализация</kwd><kwd>кальцификация</kwd><kwd>элементный анализ</kwd><kwd>фосфат кальция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atherosclerosis</kwd><kwd>calcific aortic stenosis</kwd><kwd>mineralization</kwd><kwd>calcification</kwd><kwd>elemental analysis</kwd><kwd>calcium phosphate</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при поддержке комплексной программы фундаментальных научных исследований СО РАН в рамках фундаментальной темы НИИ КПССЗ № 0546-2019-0002 «Патогенетическое обоснование разработки имплантатов для сердечно-сосудистой хирургии на основе биосовместимых материалов с реализацией пациент-ориентирован-ного подхода с использованием математического моделирования, тканевой инженерии и геномных предикторов»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Shi X., Gao J., Lv Q., Cai H., Wang F., Ye R., Liu X.
