No diatoms were found in the unmixed waters of the White Sea. However, marine and freshwater diatoms were found in mixed waters (mouths of the Nizhniy Vyg River and the 19th lock of the White Sea-Baltic Canal). Desalination of seawater in the coastal zones of the White Sea reduces its salinity to isotonic values and even lowers it. This promotes the penetration of marine and freshwater diatoms contained in the water into the bloodstream of victims dying from drowning.Conclusions: The obtained results justify the relevance of examining the internal organs in cases of drowning in the coastal waters of the White Sea.","PeriodicalId":35704,"journal":{"name":"Sudebno-Meditsinskaya Ekspertisa","volume":"67 6","pages":"48-51"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142883208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conducted exploratory analysis allows hypothesizing the dependence of impedance values and dispersion factors for the diagnostic zones studies on the postmortem interval; it also suggests that it is possible to determine this interval for the objects (pig corpses) studies with a combination of impedance values and the corresponding factors. Among large mammals, a swine is the closest to a human from the point of analyzing the postmortem period process, and it can be recommended as an adequate human corpse model. When determining the correlation between the postmortem interval and the impedance parameters, it is the simplicity and reproducibility of the method, the absence of expensive equipment, its portability and the rapid receipt of results that allow this method to be applied at the scene, reinforcing traditional forensic methods for determining the prescription of death coming. Interpretation of impedance monitoring results can be used to analyze the biological nature of the postmortem period processes.","PeriodicalId":35704,"journal":{"name":"Sudebno-Meditsinskaya Ekspertisa","volume":"66 2","pages":"20-25"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9739038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was detected that only Deuteromycota and Eubacteria colonized all types of surfaces in the samples of bone fragments from the historic burial site (with the age in the range of 90-95 years); with the abundance of micromycetes, the proportion of Eubacteria naturally decreased, while with the increased bacterial background counts the rate of micromycetes detection decreased. The insignificant amount of nutrients in the bony remnants led to the decrease in the number and biological diversity of microorganisms contaminating them; species adapted to a hard-to-reach organic substrate dominated there. During the process of bony remnants decomposition, when the conditions of their location changed, inter-species competition and specific recolonization occurred by species of microorganisms most adapted to a hard-to-reach organic substrate in the abiotic and biotic conditions of existence given. The results obtained are important for the descriptive ecology and biology of specific groups of microorganisms in the postmortem microbiome and form the basis for a more thorough study of complex communications between species of microorganisms in the necrobiome of bony remnants - in the future it will allow putting forward original hypotheses about the involvement of microbes in the circulation of matter and energy, as well as to apply the information obtained in the evidence base of forensic examination and forensic archaeology.","PeriodicalId":35704,"journal":{"name":"Sudebno-Meditsinskaya Ekspertisa","volume":"66 2","pages":"30-36"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9739039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Semilethal (890 mg/kg) dose of lercadipine, previously suspended in water, was injected into stomach of laboratory animals. Examined substance was isolated from the thick tissues and animals' blood by acetone, cleaned with a change of solvent and macrocolumn chromatography using 30 µm «Silasorb S-18» sorbent and acetonitrile-water (8:2) polar eluent. The analyte was identified by chromatographic behavior in the thin sorbent layer, retention time and set of positive ions in its mass spectrum, as well as by UV-spectrum. The analyte was determined quantitatively in bioactive matrix using UV-spectrophotometry. The methods were validated by criteria of linearity, selectivity, accuracy, precision, detection limits and quantitative determination.

The number of experimental firings equal 19 was done by 3 shots at the distance from close range to 250 cm. The examination of shot targets was carried out using the visual, metric, stereoscopic (Leica 125M microscope) methods, in ultraviolet rays (LUMATEC SUPERLITE M Series light).Results: The nature and morphology of distribution of gunshot residue on targets' surfaces made it possible to establish close range firing zones. The nature in which soot is deposited during shot under the conditions of point-blank range and in the first zone of close range (up to 8 cm) allows to establish the position of weapon's transverse plane relative to the target basing on a specific blowout of a gas-powder jet from special design of flame arrestor. The performed experimental shooting from hunting self-loading Steyr Mannlicher AUG-Z3 carbine made it possible to determine the metric and morphological characteristics of the close range firing zones: 1 zone is equal a distance up to 8 cm; 2 zone - up to 30 cm; 3 zone - up to 100 cm from muzzle of weapon. The design features of Steyr Mannlicher AUG-Z3 carbine's flame arrestor allow to identify the type of weapon according to the morphological pattern of target's damage. The complex of obtained data makes it possible to determine the firing distance with high accuracy.","PeriodicalId":35704,"journal":{"name":"Sudebno-Meditsinskaya Ekspertisa","volume":"66 6","pages":"13-17"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138811652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
