Shevlyuk, celebrated his 75th birthday. He was born on December 10, 1950, in the village of Linovitsk, Martuk District, Aktobe Region, Kazakh SSR, into a family of workers at the Shevchenko Machine and Tractor Station. In 1972, after graduating with honors from the Orenburg Pedagogical Institute (Faculty of Natural Geography, Department of Biology and Chemistry), Shevlyuk entered postgraduate studies at the Department of Histology, Cytology, and Embryology of the Orenburg Medical Institute. Upon completing his postgraduate training in 1975, he remained at the department, where he advanced from Assistant to Professor: 1975–1990 — Assistant; 1990–1998 — Associate Professor; since 1998 — Professor. Alongside his main position, from 1998 to 2006, Professor Shevlyuk worked at the Laboratory of Functional Cell Morphology of the Institute of Cellular and Intracellular Symbiosis, Ural Branch of the Russian Academy of Sciences, first as Senior, and later as Leading Researcher. From 2000 to 2017, he concurrently served as Professor at the Department of Zoology and Ecology of Orenburg State Pedagogical University. Shevlyuk was awarded the Candidate of Sciences in Biology degree in 1978 and the Doctor of Sciences in Biology degree in 1998; the academic title of Associate Professor in 1991 and that of Professor in 2000. Professor Shevlyuk is one of the leading scholars in the fields of ecological-morphological, comparative, and evolutionary histology, morphogenesis and regeneration, the history of science, and the methodology of teaching histology. The analysis of the vast body of factual material he has accumulated is reflected in an impressive number of scientific publications. Professor Shevlyuk was the first to describe the ultrastructure of Leydig cells in the testes of several vertebrate species and to identify key directions of adaptive transformations in testicular endocrinocytes under various destabilizing influences. Nikolai N. Shevlyuk founded the major Orenburg school of histology, whose cornerstone is the study of ecological morphology of the reproductive organs of vertebrates inhabiting anthropogenically transformed and natural ecosystems of the steppe zone of the Southern Urals. He has served as the head of this school for about 25 years. Colleagues, students, and the editorial board of the Morphology journal sincerely wish Professor Nikolai N. Shevlyuk good health, family happiness, unfailing optimism, and new scientific and creative achievements.</p></abstract><trans-abstract xml:lang="ru"><p>В декабре 2025 года исполнилось 75 лет известному отечественному гистологу, педагогу, доктору биологических наук, профессору, профессору кафедры гистологии, цитологии и эмбриологии Оренбургского государственного медицинского университета, заслуженному работнику высшей школы Российской Федерации Шевлюку Николаю Николаевичу. Он родился 10 декабря 1950 года в Казахской ССР, в посёлке Линовицк Мартукского района Актюбинской области в семье работников Шевченковской машинно-тракторной станции. В 1972 году, после окончания с отличием Оренбургского педагогического института (естественно-географический факультет, отделение биологии-химии), Н.Н. Шевлюк поступил в аспирантуру при кафедре гистологии, цитологии и эмбриологии Оренбургского медицинского института. После окончания аспирантуры в 1975 году он остался работать на кафедре, где прошёл путь от ассистента до профессора: 1975–1990 гг. — ассистент, 1990–1998 гг. — доцент, с 1998 года по настоящее время — профессор кафедры. Одновременно с работой на кафедре в 1998–2006 гг. Николай Николаевич работал в лаборатории функциональной морфологии клетки Института клеточного и внутриклеточного симбиоза Уральского отделения Российской академии наук, сначала старшим, а затем ведущим научным сотрудником. Кроме того, в 2000–2017 гг. он по совместительству работал на кафедре зоологии и экологии Оренбургского государственного педагогического университета в должности профессора кафедры. Учёная степень кандидата биологических наук присвоена Н.Н. Шевлюку в 1978 году, а доктора биологических наук — в 1998 году; учёное звание доцента — в 1991 году, а учёное звание профессора — в 2000 году. Николай Николаевич является одним из ведущих учёных в области изучения проблем эколого-морфологической, сравнительной и эволюционной гистологии, морфогенеза и регенерации, вопросов истории науки, а также методики преподавания гистологии. Анализ колоссального массива накопленного им фактического материала отражён во внушительном количестве научных работ. Профессор Н.Н. Шевлюк впервые описал ультраструктуру клеток Лейдига в семенниках некоторых позвоночных и выявил основные направления адаптационных перестроек эндокриноцитов семенников при различных дестабилизирующих воздействиях. Николай Николаевич создал крупную Оренбургскую научную гистологическую школу, краеугольным камнем которой стало изучение проблем экологической морфологии органов репродуктивной системы позвоночных, населяющих антропогенно преобразованные и естественные экосистемы степной зоны Южного Урала. Научным руководителем этой школы Н.Н. Шевлюк является уже около 25 лет. Коллеги и ученики, а также редакция журнала «Морфология» искренне желают Николаю Николаевичу Шевлюку доброго здоровья, семейного счастья, неиссякаемого оптимизма, новых научных и творческих побед, благополучия.</p></trans-abstract><trans-abstract xml:lang="zh"><p>2025年12月，俄罗斯著名组织学家、教育家、生物学博士、教授、俄罗斯联邦功勋高等教育工作者、Orenburg State Medical University组织学、细胞学与胚胎学教研室教授Nikolai N. Shevlyuk迎来了七十五岁诞辰。Shevlyuk教授1950年12月10日出生于Kazakh SSR, Aktobe Region, Martuk District, Linnovitsk村的一个机械拖拉机站职工家庭。1972年，他以优异成绩毕业于Orenburg Pedagogical Institute（自然地理系生物化学专业），并考入Orenburg Medical Institute组织学、细胞学与胚胎学教研室研究生班。1975年研究生毕业后留校任教，历任助教1975至1990年，副教授1990至1998年，自1998年至今任该教研室教授。1998年至2006年间，Shevlyuk教授同时在俄罗斯科学院Ural分院Institute of Cellular and Intracellular Symbiosis的细胞功能形态学实验室工作，先后担任高级研究员与首席研究员。此外，2000年至2017年间，他兼任Orenburg State Pedagogical University动物学与生态学教研室教授。Shevlyuk教授于1978年获生物学副博士学位，1998年获生物学博士学位；1991年获副教授学衔，2000年获教授学衔。Shevlyuk教授是生态形态学、比较与进化组织学、形态发生与再生、生物学史以及组织学教学方法等领域的杰出学者。他所积累的庞大事实资料经过系统分析，已反映在数量可观的科学论文中。Shevlyuk教授首次描述了部分脊椎动物睾丸间质细胞（Leydig细胞）的超微结构，并揭示了在不同不利因素作用下睾丸内分泌细胞的适应性重塑规律。Shevlyuk教授创建了具有重要影响力的Orenburg组织学学派，其核心研究方向为Southern Urals草原地带脊椎动物生殖系统器官的生态形态学，重点探讨生活于人为改造及自然生态系统中的动物形态适应问题。Shevlyuk教授作为该学派的学术带头人，已担任其科研指导约二十五年。同事与学生们以及《Morphology》杂志编辑部，衷心祝愿Shevlyuk教授身体健康、家庭幸福、乐观长存，并在科学与创造的道路上取得新的成就与荣誉。</p></trans-abstract><kwd-group xml:lang="en"><kwd>N.N.
