Item Invasive Breast Carcinoma of No Special Type with Medullary Pattern: Morphological and Immunohistochemical Features(Turkish Journal of Pathology, 2022) Линдін, Микола Сергійович; Lyndin, Mykola Serhiiovych; Гирявенко, Наталія Іванівна; Hyriavenko, Nataliia Ivanivna; Сікора, Владислав Володимирович; Sikora, Vladyslav Volodymyrovych; Линдіна, Юлія Миколаївна; Lyndina, Yuliia Mykolaivna; Soroka, Y.; Романюк, Анатолій Миколайович; Romaniuk, Anatolii MykolaiovychObjective: Our study investigated the morphological and immunohistochemical characteristics of invasive breast carcinoma of no special type (IBC-NST) with medullary pattern to explore the inconsistencies between the structural and clinical traits of this category of tumor. Material and Method: The breast carcinoma samples (n = 26) with medullary pattern (defined according to established criteria) were subjected to immunohistochemical assays of the following receptors: ER, PR, HER2/neu, Ki-67, p53, Bcl-2, VEGF, MMP1, E-cadherin, EGFR, Hsp70, Hsp90, CD20, CD3, CD4, CD8, CD68, CD163, CD56, CD138, MPO, S100, IgG, IgM, and PD-L1. Results: IBC-NST with medullary pattern was found to have negative expression of ER, PR, and HER2/neu; strong positive expression of Kі-67, mutant р53, Bcl-2, E-cadherin, EGFR, and PD-L1; moderate positive expression of Hsp70 and Hsp90; and low or negative expression of VEGF and MMP1. Furthermore, there was pronounced variability in the qualitative composition of tumor immune infiltrates with regards to T-lymphocytes, B-lymphocytes, macrophages, plasmocytes, and granulocytes. Conclusion: IBC-NST with medullary pattern has many unfavourable morphological and immunohistochemical prognostic characteristics, which are balanced against the pronounced protective properties of the tumor cells and the qualitative characteristics of the tumor microenvironment. These can lead to a favourable disease course despite the relatively adverse features of the carcinoma cells.Item Morphological Peculiarities of Parasitic (Trichosomoides crassicauda) Infection in Rat Urinary Bladder(Sciendo, 2021) Сікора, Владислав Володимирович; Сикора, Владислав Владимирович; Sikora, Vladyslav Volodymyrovych; Линдін, Микола Сергійович; Лындин, Николай Сергеевич; Lyndin, Mykola Serhiiovych; Гирявенко, Наталія Іванівна; Гирявенко, Наталья Ивановна; Hyriavenko, Nataliia Ivanivna; Москаленко, Роман Андрійович; Москаленко, Роман Андреевич; Moskalenko, Roman Andriiovych; Линдіна, Юлія Миколаївна; Лындина, Юлия Николаевна; Lyndina, Yuliia Mykolaivna; Сікора, Катерина Олексіївна; Сикора, Екатерина Алексеевна; Sikora, Kateryna Oleksiivna; Чижма, Руслана Анатоліївна; Чижма, Руслана Анатольевна; Chyzhma, Ruslana Anatoliivna; Дяченко, Олена Олегівна; Дяченко, Елена Олеговна; Diachenko, Olena Olehivna; Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii MykolaiovychTrichosomoides crassicauda (T. crassicauda) is a parasite commonly localized in the urinary bladder (UB) of laboratory and wild rats. The presence of these helminths can influence the prediction of pathological changes in the UB. Therefore, the purpose of this research was to make a comprehensive study of the features of the morphological changes in the UB wall of white laboratory rats as a result of T. crassicauda infestation. The study was performed on male rats using histological (Hematoxyline-Eosin and Alcian Blue staining) and immunohistochemical (Ki-67, Hsp70, Hsp90α, CD3 and CD20) methods. T. crassicauda was detected in both urine and UB samples. Morphological changes were observed as disruption in urothelial cell stratification and insignificant proliferative and immune responses in the UB. Increased heat shock protein levels were observed which may suggest a natural body’s resistance to this parasite.Item Effect of heavy metals on microstructural and microelemental changes in the rats urinary bladder(Springer, 2020) Сікора, Владислав Володимирович; Сикора, Владислав Владимирович; Sikora, Vladyslav Volodymyrovych; Линдін, Микола Сергійович; Лындин, Николай Сергеевич; Lyndin, Mykola Serhiiovych; Гирявенко, Наталія Іванівна; Гирявенко, Наталья Ивановна; Hyriavenko, Nataliia Ivanivna; Линдіна, Юлія Миколаївна; Лындина, Юлия Николаевна; Lyndina, Yuliia Mykolaivna; Москаленко, Роман Андрійович; Москаленко, Роман Андреевич; Moskalenko, Roman Andriiovych; Піддубний, Артем Михайлович; Поддубный, Артем Михайлович; Piddubnyi, Artem Mykhailovych; Сікора, Катерина Олексіївна; Сикора, Екатерина Алексеевна; Sikora, Kateryna Oleksiivna; Kuts, V.Global environmental pollution leads to the distribution of heavy metal salts (HMS) in the ecosystem and their impact on the organism.

The purpose of our research is to study structural and functional features of articular cartilage at light optical level by using state-of-the-art research methods of bone-cartilage tissue. Material and Methods: The study was conducted on samples of femoral heads. Hyperfine sections were subject to hematoxylin and eosin, Van Gieson’s and PAS staining. In order to identify the receptor profile of chondrocytes and the features of protein arrangement in extracellular matrix we undertook an immunohistochemical study. Results: An articular cartilage is quite organized tissue. As any other organ, it has parenchyma and stroma. Parenchyma is represented by one type of cells — chondrocytes, which, depending on how deep they are located in cartilage, have a diff erent shape, size and functional features. The chondrocytes and extracellular matrix have diff erent degrees of receptors expression. Conclusions: The cartilage is being constantly self-renewed, what is manifested by means of a rather slow division of the surface-located chondrocytes and programmed death of dystrophic-modifi ed cells. The features of extracellular matrix structure determine the originality of cell location in different areas of cartilage tissue. Due to synthesis of specific proteins, chondrocytes self-regulate properties of cartilage tissue.Item Immunohistochemical characteristics of aortic valve in the case of atherocalcinosis(Springer, 2017) Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii Mykolaiovych; Москаленко, Роман Андрійович; Москаленко, Роман Андреевич; Moskalenko, Roman Andriiovych; Закорко, Інна-Маргарита Сергіївна; Закорко, Инна-Маргарита Сергеевна; Zakorko, Inna-Marharyta Serhiivna; Линдін, Микола Сергійович; Лындин, Николай Сергеевич; Lyndin, Mykola Serhiiovych; Піддубний, Артем Михайлович; Поддубный, Артем Михайлович; Piddubnyi, Artem Mykhailovych; Сікора, Владислав Володимирович; Сикора, Владислав Владимирович; Sikora, Vladyslav Volodymyrovych; Линдіна, Юлія Миколаївна; Лындина, Юлия Николаевна; Lyndina, Yuliia Mykolaivna; Romaniuk, S.A.; Ящішин, Ігор Олександрович; Ящишин, Игорь Александрович; Yashchishyn, Ihor OleksandrovychObjective: According to the results of the Euro-Heart Survey on Vascular Heart Disease the most common pathology is nonrheumatic aortic stenosis, it is also called as calcific aortic valve stenosis (CAVS), as in its pathogenesis the process of biomineralization of valve cusps and ring plays the main role.Item Peculiar features of CEACAM1 and E-cadherin expression in the uterus(Springer, 2018) Линдін, Микола Сергійович; Лындин, Николай Сергеевич; Lyndin, Mykola Serhiiovych; Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii Mykolaiovych; Сікора, Владислав Володимирович; Сикора, Владислав Владимирович; Sikora, Vladyslav Volodymyrovych; Гирявенко, Наталія Іванівна; Гирявенко, Наталья Ивановна; Hyriavenko, Nataliia Ivanivna; Kravtsova, Olha Ivanivna; Panchenko, V.V.; Линдіна, Юлія Миколаївна; Лындина, Юлия Николаевна; Lyndina, Yuliia Mykolaivna; Singer, B.B.; Кравцова, Ольга Іванівна; Кравцова, Ольга ИвановнаBackground & Objective: The aim of our study was to characterize the expression pattern of сarcinoembryonic antigen related cell adhesion molecule 1 (CEACAM1) and E-cadherin in normal, hyperplastic and tumour tissues of the uterine, and to determine the potential correlation between these two adhesion molecules.Item Peculiarities of megakaryocytes and platelets variation in the microelementosis condition(Springer, 2019) Линдіна, Юлія Миколаївна; Лындина, Юлия Николаевна; Lyndina, Yuliia Mykolaivna; Сікора, Владислав Володимирович; Сикора, Владислав Владимирович; Sikora, Vladyslav Volodymyrovych; Гирявенко, Наталія Іванівна; Гирявенко, Наталья Ивановна; Hyriavenko, Nataliia Ivanivna; Линдін, Микола Сергійович; Лындин, Николай Сергеевич; Lyndin, Mykola Serhiiovych; Карпенко, Людмила Іванівна; Карпенко, Людмила Ивановна; Karpenko, Liudmyla Ivanivna; Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii MykolaiovychBackground & Objectives: The aim of our study was to characterise megakaryocytes and platelets variation under the influence of heavy metal salts and determine the peculiarities of these changes in recovery period. Methods: The laboratory rats (n=48) were used for the conduction of experimental investigation. They were divided into two groups: control – animals which drank clean water and experimental – rats which drank water with heavy metal salts (Zn, Cu, Fe, Mn, Cr and Pb). The bone marrow structure and blood parameters were studied on 30, 90, 120 and 180 day. Results: During 90 days of intoxication the amount of megakaryocytes increased on 40%(р=0.017). There were changes of shape, size (small and giant), nuclear-cytoplasmic ratio, polysegmentation of nuclei and loss of megakaryocyte-sinusoid contacts. It was found the platelets increase by 11% in the blood. Suspending the addition of pollutants to the animal's diet was accompanied by progressive restoration of bone marrow-blood parameters. Simultaneously with disappearance of megakaryocytes morphological variations the area of thrombocytopoiesis was decreased by 28%, the thrombocytes – by 5.3%. Conclusion: The intake of heavy metal salts in elevated concentrations provokes significant disorders in thrombocytopoiesis which leads for platelets increase in the blood. Although there was a significant improvement bone marrow-blood characteristics during recovery period, their values do not reach the indicators of the intact group animals.Item The features of morphological changes in the urinary bladder under combined effect of heavy metal salts(Interventional Medicine & Applied Science, 2017) Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii Mykolaiovych; Сікора, Владислав Володимирович; Сикора, Владислав Владимирович; Sikora, Vladyslav Volodymyrovych; Линдін, Микола Сергійович; Лындин, Николай Сергеевич; Lyndin, Mykola Serhiiovych; Сміянов, Владислав Анатолійович; Смиянов, Владислав Анатольевич; Smiianov, Vladyslav Anatoliiovych; Сікора, Володимир Віталійович; Сикора, Владимир Витальевич; Sikora, Volodymyr Vitaliiovych; Линдіна, Юлія Миколаївна; Лындина, Юлия Николаевна; Lyndina, Yuliia Mykolaivna; Піддубний, Артем Михайлович; Поддубный, Артем Михайлович; Piddubnyi, Artem Mykhailovych; Гирявенко, Наталія Іванівна; Гирявенко, Наталья Ивановна; Hyriavenko, Nataliia Ivanivna; Коробчанська, Анна Борисівна; Коробчанская, Анна Борисовна; Korobchanska, Anna BorysivnaAbstract: Purpose: This study is aimed to the investigation of the features of morphological changes in the urinary bladder of mature rats. Results: Received results shown that the experimental group of rats that had the intake of heavy metal salts (HMS) mixture during 30 and 90 days were observed histological and immunohistochemical changes in all structures of the urinary bladder. Depending on the period of influence of heavy metal ions on the wall of the organ, the pathological changes developed in cellular layers of the wall can lead to degenerative and later to atrophic and sclerotic changes. Conclusions: This study demonstrates that high concentrations ofHMS can significantly influence the body. The histological and immunohistochemical studies showed that the influence of the HMS combination leads to deep morphological changes in all structures of the urinary bladder. These changes depend on the period of intake of HMS. Analysis of the obtained results demonstrates the dependence of expression of morphological changes in the urinary bladder on the experiment duration. The final result of these changes may lead to the disorders of bladder’s functions.Item Effect of heavy metals on the readaptive processes in the urinary bladder(Bangladesh Academy of Sciences, 2019) Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii Mykolaiovych; Сікора, Владислав Володимирович; Сикора, Владислав Владимирович; Sikora, Vladyslav Volodymyrovych; Линдіна, Юлія Миколаївна; Лындина, Юлия Николаевна; Lyndina, Yuliia Mykolaivna; Линдін, Микола Сергійович; Лындин, Николай Сергеевич; Lyndin, Mykola Serhiiovych; Гирявенко, Наталія Іванівна; Гирявенко, Наталья Ивановна; Hyriavenko, Nataliia Ivanivna; Карпенко, Людмила Іванівна; Карпенко, Людмила Ивановна; Karpenko, Liudmyla Ivanivna; Піддубний, Артем Михайлович; Поддубный, Артем Михайлович; Piddubnyi, Artem Mykhailovych; Miroshnichenko, M.Introduction: Heavy metals (HM) are dangerous elements due to their toxicity and prevalence play an important role in the environmental pollution and hazards to health risk.
