The article presents a review of scientific and educational activities of the Department of Forensic Medicine of Sechenov University in different historical periods of establishment and development. The information about founders of the domestic forensic medicine, who held the position of the head of the department in the period from 1804 to 2024, their contribution to the development of forensic medical science and the main scientific research directions is given. The modern stage of the department's existence under the leadership of Yu.I. Pigolkin is marked by new successes and scientific achievements based on continuity and preservation of the department's traditions for 220 years.

Objective: To assess the adequacy of linear function of calibration according to GOST R ISO 11095-2007 for ethanol mass concentration measurement using internal reference materials (RMs).

Material and methods: An experiment on calibration in accordance with the GOST R ISO 11095-2007 National standard of the RF was carried out using internal RMs, namely aqueous solutions of ethanol at different concentrations. Measurements were performed for two subbands of ethanol concentrations at RMs: 0.15-1.05 and 1.0-7.0 mg/ml - according to the certified methodology.

Results: The graphs of the calibration's functions based on experimental data are consistent with the assumption of the calibration function's linearity, as well as the assumption of the standard deviation's constance of residues is equitable for two subbands of RMs.

Conclusion: Proven linear models in the calibration experiment may be recommended for use in the ethanol mass concentration measurement.

The objective of the study: Is to identify the main communication problems encountered by forensic medical experts and specialists during the interdepartmental interaction, and to develop proposals to overcome them. A comprehensive approach was used to achieve the aim of the research, including the carrying out of a qualitative focus group interview of forensic medical experts and resident doctors. The main communicative problems have been determined and proposals for their elimination have been formulated, the types of communication trainings on interdepartmental interaction have been identified.

Objective: To systematize the mechanisms of formation and morphology of secondary ischemic brain damage, formed in the case of craniocerebral injury.

Material and methods: A literature review devoted to the study of formation mechanisms of secondary ischemic brain damage in craniocerebral injury was conducted. The secondary sequential and secondary long-term ischemic brain damage in the posttraumatic period, as well as intracranial and extracranial factors that contribute to their occurrence and progression, were considered.

Results and conclusion: Analysis of the literature has shown that primary lesions occurring at the time of head injury must be differentiated from sequential and long-term secondary ischemic changes in different brain structures.

The objective of the study is to analyze existing measures and identify problematic aspects of ensuring the organization of infectious safety activity in forensic medical expert institutions, to develop ways of their solution. Documents regulating the functional principles of forensic medical expert institutions in cases of detection or suspicion of infectious pathology have been examined. Specific proposals for the development of a system to ensure infectious safety in the organization of work in the bureau of forensic medical expertise have been formulated.

The objective of the study: Is to identify the effectiveness of cooperation between forensic expert institutions on the basis of approaches to determining their one-pointedness. Legislative and regulatory legal acts regulating forensic expert activity have been studied. Methods of synthesis, analysis and comparison have been used for their processing. The comparison of the carrying out of targeted diversified studies has been conducted. The article substantiates a necessity of uniform approaches to determination of one-pointedness of forensic expert institutions in order to increase the effectiveness of interdepartmental interaction.

The aim of the work is to study the nature of the distribution of 2-A-4.6-DNP in the organisms of warm-blooded animals with intragastric administration of a toxicant. The study was carried out using the methods of TLC, UV-Visible spectroscopy, and GC-MS using derivatives of 2-A-4.6-DNP. Male Wistar rats at the age of 4 months were considered as a model of the body of a warm-blooded animal. An oily suspension of 2-A-4.6-DNF was administered intragastrically in an amount of three times the LD₅₀. Extraction of the target substance from the biomaterial was carried out by double infusion (30 minutes each) with a mixture of acetone-acetonitrile (1:1), the amount of the mixture exceeded the weight of the biomaterial by 2 times. Extractions were purified by TLC method using «Sorbfil» plates and acetone-chloroform (7: 3) mobile phase. Preliminary identification was carried out at the same time using a standard substance. Confirmatory identification was carried out by the absorption of dimethylformamide eluates in «SF-2000», as well as by the retention time and mass spectra of the major compound of the corresponding chromatographic peaks after GC-MS analysis. The quantitative content was determined spectrophotometrically, in DMF, by optical density at the analytical wavelength (490 nm). 2-Amino-4.6-dinitrophenol was found unchanged in the blood and in all the studied hollow and parenchymal organs of poisoned rats. The largest amount of 2-amino-4.6-dinitrophenol (mg/100 g) was found in the stomach walls (199.39±25.43) and stomach contents (143.14±22.63), a significant amount of the substance was found in the heart (33.49±3.66), skeletal muscles (30.70±2.64), as well as in the spleen (24.30±1.96).

The objective of the study is to determine the possibility and the right to choose the directions of self-education and self-development by forensic medical experts within the framework of personal and professional development program in the educational trajectory formation. The materials of special and encyclopaedic literature including pedagogical and sociological sciences, as well as legal framework regulating the processes of continuing medical education have been studied. The choice of educational trajectory of forensic physician depending on personal benchmarks, self-education building and participation in educational activities has been defined.

A technology of mobile devices on the basis of Android and iOS sharing, in which previously trained neural networks on the mobile device with the use of the Skull-face program place the reference points in automatic mode with subsequent analysis of the images and obtaining the result in less than 1 min, has been developed. Data processing and acquisition of results immediately at the scene of an accident can provide invaluable assistance in the mass admission of unidentified corpses in cases of emergency; will allow to rapidly, excluding the influence of subjective factor, solve expert tasks, improve the accuracy, effectiveness and performance of forensic personality identification.

Objective: To study the influence of COVID-19, as well as various factors on the rate of deaths caused by suicide.

Material and methods: The statistical analysis of mortality according to the data of «Bureau of FME» in the period from 2019 to 2020 yrs. and the search of scientific publications over the past 10 years in PubMed database have been conducted. Articles describing the factors influencing suicidal deaths in different population groups were selected from the publications.

Results: Statistically significant features that determine the influence of quarantine measures in the period COVID-19 on the mental component of citizens and suicidal dynamics were considered and established.
