The paper presents a scientific biography of the well-known scientist and teacher, Honored Scientist of the Russian Federation, Head of the Department of General Hygiene and Ecology of the Razumovsky Saratov State Medical University, Dr Sci. (Med.), Professor Yury Yu. Eliseev, on the occasion of his 70th birthday. The main stages of the Professor's activities over the entire period of his research and teaching work are analyzed. Yu.Yu. Eliseev carries out extensive research, educational, methodological, expert and consulting work. Under the Professor's supervision, more than 70 doctoral and PhD theses have been prepared and successfully defended. A total of 76 monographs, textbooks, and teaching aids have been issued, 32 copyright certificates for inventions, Russian Federation patents, certificates for registration of electronic databases, computer programs have been implemented, a number of production regulations, pharmacological articles, instructions for the use of new preventive medical immunobiological preparations (vaccines and diagnostic serums), and hygienic regulatory documents have been developed. The launch of two postgraduate courses in the specialties "Hygiene" and "Allergology and Immunology" managed by Yu.Yu. Eliseev has been initiated. Professor is a member of editorial boards of seven journals, he has state awards of various levels. The results of the Yu.Yu. Eliseev’s work presented have made it possible to respond to numerous challenges faced by scientific community in different years, and the vector of scientific and pedagogical work that he has set is promising in terms of solving hygienic problems, as well as resolving the issues of training and education.

Currently, given the high risk of exposure of the country's population to various adverse factors in the context of everyday life, it is important to promote efforts aimed at improvement of the people's health, its physical aspect in the first place. Establishing the state of the population's physical health management system is a significant part of this process. This study aimed to look into the current organizational and methodological aspects of the development of the physical health management system designed for adults and children in the regions of the country. For this purpose, we surveyed heads of regional government bodies using a 40-item questionnaire that had both multiple choice and grid-in questions. The questionnaires were sent to all regions of the country; 59 of them got filled by the respective officials and returned. The filled questionnaires were subsequently systematized and processed. Having analyzed the responses received, we classified the promoting and limiting factors that affect the development of the adults and children physical health management system. This exercise was designed to yield data needed to support the development of the national (regional, municipal) system underpinning physical culture and sports popularization, the GTO movement (Ready for Labor and Defense), and training of elite athletes. We have also prepared the "Classification of examples of the best management solutions," the "Consolidated list of proposals to improve the regional physical health management system for adults and children," and the "Collection of assistance requests issued by the regions to the federal authorities." Thus, analyzing the responses from the participating regions allowed learning their experience in managing the physical health of both adults and children.

The basics of student youth health all over the world are ensured by factors of the educational environment and the young adults’ lifestyle. Modeling of such conditions is possible with comprehensive assessment of the quality and safety of university internal environment, update of modern educational spaces in response to the students’ need for motor activity and physical exercises. Currently, it becomes increasingly necessary to pay attention to the hygienic factors affecting shaping proper posture in university students. The main focus is on such aspects, as learning conditions, workplace organization, physical activity, and other daily habits that contribute to either impairment, or maintenance of healthy posture. There is no need to emphasize the importance of proper workplace organization. The height of the desk and chair, the level of the monitor, the quality of the furniture and lighting play a key role in maintaining a comfortable and safe body position during classes. Incorrect organization can result in developing musculoskeletal disorders and postural alterations. Physical activity and regular breaks while learning are considered important prerequisites for preservation of the students’ musculoskeletal system functional disorders. Students leading a sedentary lifestyle face the risk of postural alterations. It is recommended short physical exercises and active breaks in the daily routine in order to improve muscle tone and reduce tension.

Exposure to harmful and dangerous factors at ore mining facilities poses health risks to workers that are associated with prolonged exposure to airborne chemicals in the work area. Realized, these risks undermine physical condition of people doing key ore mining jobs underground. Relying on the target protein analysis, this study aimed to assess the job-related harm to the health of ore mining workers resulting from exposure to metals airborne in the work zone. The participants were involved in copper-nickel ores mining. To evaluate the impact of metals from the working zone air on their health, we conducted chemical, proteomic, statistical, and bioinformatic analyses on the collected samples and data. With the mean per-shift exposure to metals of up to 0.2 mg/m³ (up to 4 times the MPC), the blood supernatant concentrations of cobalt, chromium, nickel, copper, and manganese increased by 1.4 to 2.6 times in the study group compared to the control group. Comparison of proteomics datasets revealed 33 significantly different protein spots. In 15 of them, the change in intensity was related to the increased concentration of the considered metals in the supernatant. Identification and analysis of proteins from these spots revealed their association with impairments in the functions of the nervous, cardiovascular, and digestive systems. The identified proteins were involved in the development of oxidative stress, metabolic and neurodegenerative disorders. Proteomic analysis improves the prediction and early prevention of occupational adverse outcomes among the ore mining industry workers.

Today, preserving the health of medical students, who constitute the labor pool for Russia's healthcare system, is a strategically important task for both the state and society. The purpose of this work was to investigate the status of health of 1st-, 2nd-, and 3rd-year students of Pacific State Medical University of the Ministry of Health of the Russian Federation. The students underwent a comprehensive examination at the beginning and at the end of the academic year. All in all, we examined 698 people in 2022 and 516 people in 2023. The examination was physical, focusing on the functional state of the cardiorespiratory system, and also assessed the participants' mental health. Primary medical documentation was used as a source of information to assess the incidence of temporary disability and chronic non-communicable diseases of students. Data comparison was done using nonparametric statistical methods. The differences were considered statistically significant at p < 0.05. We revealed a downward trend for the students' health indicators, which confirms their allocation into health status groups. At the beginning of the academic year, the 1s group was the largest, and by its end, the share of those reallocated to the 3rd group was significant, with the group including 33.1% of make participants and 36.8% of female participants.  This study substantiates the need for continued monitoring of the health status of students. The resulting data enable assessment of the students' health status and identification of priority preventive measures to be developed to preserve their health.
