An environmental analysis of the activity of bioflavonoid accumulation in medicinal plants

Abstract

This article presents experimental data on the rutin, catechin, and leucoanthocyanin content in medicinal plants (66 species from 31 families). A significant correlation between the catechine and leucoanthocyanin content in plant tissues (r = 0.89) is observed. The study identified promising plant species with a high content of bioflavonoids. These plants can be used as a basis for developing innovative functional foods that exhibit high antioxidant activity.

Gender and seasonal characteristics of lipid exchange in people of different ages

Abstract

A biochemical assay of blood lipids in military personnel and reservists was conducted. The influence of seasonal changes (spring, autumn) on the lipid compounds of blood serum was analyzed. A dependence between the total cholesterol level, the content of low-density (LDL) and high-density lipoproteins (HDL, and triglycerides and age and gender was identified.

The modelling of postmortem heat transfer and estimating the time of death

Abstract

This article analyses different mathematical models of the process of postmortem heat transfer in an adult cadaver based on postmortem temperature dynamics. A model of heat transfer in a newborn cadaver presented as a finite cylinder is examined in detail. An important factor in constructing a mathematical model of postmortem heat transfer in a newborn aimed at identifying the time of death is body form approximation. It is shown that heat transfer in a cadaver is not sufficient for identifying the time of death, which should be based on a comprehensive assessment of postmortem changes.

Characteristics of traumatic fragmentation of the body and personal identifi-cation in cases of mass casualties as a result of manmade emergencies

Abstract

Practical material is used to analyze the frequency of applying different personal identification methods in the cases of traumatic body fragmentation in different manmade emergencies. The authors estimate the identification efficiency of dental characteristics depending on the damaging factor in different manmade emergencies. It is shown that the significance of forensic postmortem dental identification increases with the intensity of damaging factors. The key method of forensic dental identification process is a comparison of an antemortem dental record with the postmortem one, which loses its significance in the absence of data for a comparative analysis. This circumstance requires a search for dental equivalents of different general and specific personal characteristics for identification purposes.
