[Mathematical simulation of the corpse's temperature change during exposure of a direct solar radiation to diagnose a postmortem interval].

Objective: To choose an optimal mathematical model and to practice the method of its use during finding the corpse under exposure of a direct solar radiation.

Material And Methods: The studies were carried out on 9 corpses with body weight from 50 to 83 kg. The influence of black (6 corpses) and white (3 corpses) colored cotton fabrics was investigated to standardize a photoreceptive surface of clothes.

[Age-related features of colonic dysbiosis in Lamblia infestation].

The purpose of the investigation was to comparatively study and to define the specific features of intestinal microbiocenosis in patients with lambliasis in different age groups of children and adults. Characterizing the age-related features of microbiocenosis in Lamblia infestation showed differences in 3 age groups: children aged less than 7 years and those aged 8-14 years, and adults; there were no statistically significant differences in the characteristics of microbiocenosis between age groups I and II, as well as age groups IV and V. Intestinal microbiocenotic changes in Lamblia infestation were less evident in the 8-14-year-old children: grade 1 microbiological changes characterized by a decrease in the normal flora were most common.

[Methodology of determination of the time of death and outlooks for the further development].

A methodological analysis of diagnosing the prescription of death coming (PDC) is described in the paper. Key philosophic fundamentals for further novel and more effective methods of PDC determination are elucidated. Main requirement applicable to postmortem diagnosis are defined.

[Effect of the weather conditions on process of temperature changes of cadaver in diagnostics of the time of death].

The impact exerted by weather conditions on the changing cadaver temperature (CCT) is described in the paper. Various meteorological phenomena influence the cadaver as an open thermodynamic system, which affects the accuracy of death prescription (DP). A variety of such impacts are described; trends for further elaboration of algorithms, which account for the environmental factors in mathematical modeling of CCD for the purpose of a more accurate DP diagnosis, are defined.

Sex determination of forensic samples by polymerase chain reaction of the amelogenin gene and analysis by capillary electrophoresis with polymer matrix.

The aim of this study was to validate an application of GenePrint Sex Determination System based on amplification of a section of the X-Y homologous gene amelogenin followed by capillary electrophoresis (CE) separation of polymerase chain reaction (PCR) products for gender testing of forensic DNA. It was found that subnanogram quantities of male and female DNA were correctly detected by this system. Experiments were performed to investigate the possibility of quantitating the X-Y chromosome-specific PCR products to disclose sex-mixed DNA samples.
