GC-MS (column DB-5MS EVIDEX (25 m×0.2 mm); stationary liquid phase of 5%-phenyl-95% dimethylpolysiloxane), TLC (Sorbfil plates, mobile phase of hexane-diethyl ether (9:1) and spectrophotometry (solvent medium - 95% ethanol) were used as methods of analysis. 2.6-di(propan-2-yl)phenol was isolated from the biomatrix (liver tissue) by infusion with a mixture of ethyl acetate-acetone (7:3). The analyte was purified by combining extraction (water-ethyl acetate system) and semi-preparative chromatography on a column of silica gel L 40/100 µm, eluent - hexane-acetone (7:3). It was found that at -22 °C, 0 °C, 12 °C, 20 °C and 30 °C 2.6-di(propan-2-yl)phenol can be present in the liver tissue for 119, 98, 70, 56 and 42 days, respectively. The possibility of mathematical description of analyte decomposition dynamics in biomaterial (liver tissue) at the considered temperatures on the basis of hyperbola equation has been studied. The experimentally calculated coefficients in the hyperbola equation (km) for temperatures -22 °C, 0 °C, 12 °C, 20 °C and 30 °C are equal to 1823, 1130, 697, 510, and 255, respectively. The dependence km on the conserving temperature (tо) was educed. The equation for the description of dependence is offered: km=30.61∙(50-to)-402.39. It is shown that this equation can be the basis for prediction of 2.6-di(propan-2-yl)phenol stability in biomaterial (liver tissue) in the temperature range from -22 °C to 30 °C.","PeriodicalId":35704,"journal":{"name":"Sudebno-Meditsinskaya Ekspertisa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9850759","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 main examined postmortem period was 1 months. Measurements were made on 3 diagnostic zones of biological object and for 5 current frequency of the study. A total of 2100 readings were taken.Results and conclusion: The studies performed in standardized conditions have showed that using impedance metrics method to diagnose prescription of death coming is possible. The analysis of only absolute impedance values is not sufficient to clarify prescription of death coming due to its undulating changes. The additional use of relative coefficients, characterizing impedance dispersion, is suggested. The study of possible using the impedance indicators of corpse's tissues to determine prescription of death coming should be performed with consideration to pathomorphology of degradation. Further study of impedance dynamics when corpse is under different conditions is necessary for development of a working algorithm to determine prescription of death coming based on tissue impedance.","PeriodicalId":35704,"journal":{"name":"Sudebno-Meditsinskaya Ekspertisa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138811740","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 found that with this type of bicycle injury, the structures of the head, chest, lower extremities, as well as the structures of the abdomen were most often injured. Injuries to the structure of the head were characterized by the formation of depressed-comminuted fractures: more often frontal-temporal, less often occipital bone. Bilateral fractures of the ribs were also quite frequent types of damage, mainly the upper ribs (up to 5-6 ribs) were damaged, most often along the midclavicular and anterior axillary lines. Lung contusions have been identified in most of the injured persons with chest structure injury. Injuries to the abdominal organs and retroperitoneal space were recorded in 22.27% of cases, with liver and spleen ruptures in the majority of cases. Spinal injuries in cyclists were detected in 13.25% of cases, injuries in the cervical spine prevailed: cervico-occipital injuries and fracture-dislocations, mainly between 1-2 and 3-4 or 6-7 cervical vertebrae with separation or contusion of the spinal cord. Injuries to the structure and organs of the pelvis in road accidents in cyclists were observed very rarely, which made it possible to distinguish this type of bicycle injuries from other types of transport and blunt injuries, in particular from automobile injuries. Injuries to the structure of the limbs of the victims were noted quite often: fractures of the upper limbs occurred when falling on the road surface and injury to the lower limbs was formed both during the contact of two vehicles and when the victims fell on the road surface.","PeriodicalId":35704,"journal":{"name":"Sudebno-Meditsinskaya Ekspertisa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9966499","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}
