Memories of Meetings with Nikolay Nikolaevich Dygalo

In the article dedicated to the memory of Nikolay Nikolaevich Dygalo, the author recalls meetings with him at conferences and symposia over a 40-year scientific career in endocrinology and the study of stress. The first meeting took place in 1981 at the All-Union Symposium “Endocrine Mechanisms of Regulation of the Body’s Adaptation to Muscle Activity” in Tartu. The last meeting was on December 6, 2023, at the All-Russian Conference with international participation “Integrative Physiology-2023,” where Nikolay Nikolaevich gave an invited lecture. The long-lasting and friendly communication with Nikolay Nikolaevich was predestined by the kind and respectful relationship between their mentors – Evgeny Vladimirovich Naumenko and Anatoly Arkadyevich Filaretov – both of whom shared a common scientific interest in studying the key hormonal system of stress, the hypothalamic-pituitary-adrenocortical system. Nikolay Nikolaevich remains remembered as a person passionate about science, always vigorously striving for new achievements, retaining the enthusiasm of his youth, and with whom it was always joyful to communicate.
