[Forensic characteristic of sudden death cases in subjects with metabolic syndrome].

Comparing pace and standard of living of the world population these days and in the end of the last century, it's quiet true that there has been a significant increase. Therewith, the number of deaths from cardiovascular diseases has increased in recent decades. Scientists around the world attribute this fact to the increase in the number of people with overweight and other metabolic disorders.

[Chromatographic analysis of hard tooth tissue to determine the age of personality].

The biochemical approach for age assessment is most appropriate in forensic medicine, as racemization of aspartic acid in bones and teeth is closely related to human biological age. The aim of the study is to assess the biochemical parameters of aspartic acid in human teeth, which can be implemented into forensic practice in Russia. Samples of dentin in amount of 20, taken from the teeth of subjects aged between 16 and 76, were examined.

[Comparative assessment of technical approaches to estimating the biological age of a person using chromatographic analysis of dentin].

The study of the amino acid composition of dentin is a new approach to determining the biological age of a person in Russia. Abroad, this method is more studied, but the authors in their research use various equipment and reagents, which makes it difficult to find the optimal technical standard for implementation in domestic practice. We studied the literature over the past 5 years on age estimation by the amino acid composition of dentin.

Radiographic assessment of third molar development in a Russian population to determine the age of majority.

Objective: To test the applicability of "Gleiser and Hunt dental staging system modified by Kohler" (GHK) to assess third molar (3 M) development in a Russian population in order to determine the age of majority.

Design: The sample consisted of 918 panoramic radiographs from Russian females (n = 551) and males (n = 367) within the age interval between 8 and 23 years. On each radiograph, 3 M development was classified based on the GHK technique.

[A method for examining the biochemical composition of dental tissues in human teeth].

In medical literature there is no single detailed standard for studying the biochemical composition of a tooth. This circumstance led to the development of a proprietary method for determining the enantiomers of aspartic acid in hard dental tissues for use in the further study of the relationship between the amino acid composition of dental tissues and the biological age of humans. Dental tissue samples obtained from living individuals aged from 20 to 50 years were studied by chromatography-mass spectrometry.

[The comprehensive evaluation of the age-specific changes in the skin].

The objective of the present study was to evaluate the age-specific changes in the skin at the anterior forearm surface of the men based on the results of the examination of 100 masculine corpses at the age varying from 18 to 80 years with the application of the low invasive techniques. The ultrasonograms were used to identify the qualitative characteristics of each skin layer being visualized with special reference to the thickness and echogenic properties of dermis and epidermis. The following parameters of the age-related changes in the skin microrelief were considered to be of particular interest: Volume (the volume of skin irregularities), SR (skin roughness), SW (skin wrinkling), and SS (skin smoothness).

[The characteristic of protein biosynthesis in brain neurons with chronic alcohol intoxication].

The objective of the present study was to evaluate the possibilities for the use of the changes in the AgNOR staining patterns in the neurons of the dorsal raphe nucleus (DRN) for the purposes of the medical differential diagnostics of the cases of death from chronic alcohol intoxication. We elucidated the characteristics of the activity of protein biosynthesis including the number and the area of the nucleoli in the nuclei of the neurons of the individuals who had died from chronic alcohol intoxication (n=20) in comparison with the subjects of the control group (n=13). To reveal the morphological structures associated with protein biosynthesis in the nucleoli of the serotoninergic neurons of the dorsal raphe nucleus in the brain, the histological preparations were stained with the use of the silver-staining technique for nucleolar organizer regions (AgNOR).

[The investigations into the amino acid composition of the tooth for the purpose of forensic medical personality identification].

The increasingly greater requirements for the new approaches to the forensic medical personality identification necessitate the extensive search for and the development of the precise methods enabling the experts to determine the general personality signs in the cases of mass mortality and the large number of victims with the conspicuous post-mortem changes in their appearance including those associated with putrefaction and strong fragmentation of the bodies. This article presents the analytical review demonstrating that determination of the victims' age in the combination with the analysis of the amino acid composition of dental tissues provides a promising tool for the investigations not only in the fields of archeology and anthropology but also for the purpose of personality identification in forensic medicine.
