[The current state of the expertise of the injuries inflicted by the power-driven sawing tools].

This review of the literature covers the major articles published during the past 40 years that treat the problem of forensic medical expertise of the injuries to human organs inflicted by the power saws with high-speed reciprocating motion of the blade (power jigsaws and sabre saws.) The authors analyze the current state-of-the-art in this field and the available possibilities for the forensic medical expertise to evaluate the injuries inflicted by the sawing devices.

[The application of dermatoglyphics as a method for the characteristic of the personality traits for the purpose of the forensic medical identification expertise].

The authors report a case of forensic medical expertise demonstrating the potential of the dermatoglyphic technique as a tool for the identification of the personality traits of unknown individuals including their race and ethnic background, biological age, constitutional characteristics, congenital and acquired pathologies and injuries. It was shown that the results of the dermatoglyphic studies agree with and complement the data obtained with the help of a set of traditional forensic medical investigations, such as urological, odontoscopic, and roentgenological ones. An important advantage of the dermatoglyphic techniques is the possibility of their application under conditions when the choice and the use of the alternative methods are limited by the specific features of the objects of forensic medical expertise and the lack of time.

[The characteristic of the construction features of the power saw blades from the results of experimental studies of power saw injuries to the long tubular bones].

The objective of the present study was to elucidate the characteristic morphological signs of the power saw injuries to human long tubular bones and thereby make possible distinguishing between those inflicted by different types of power jigsaws. The experiments were carried out with the use of the power saws with high-speed reciprocating motion of the blade (power jigsaws and sabre saws). The study was focused on the experimental saw injuries to the human long tubular bones inflicted by the power jigsaws and sabre saws.

[Determination of the power jigsaw sawing velocity from the morphological properties of the affected human skin].

The objective of the present work was to elucidate the characteristic morphological features of the injuries inflicted to the human skin by a power jigsaw depending on the sawing velocity. The study has demonstrated the possibility of mathematical analysis of the sawing velocity based on the morphological peculiarities of the injury to the skin. The data obtained indicate that forensic medical expertise of the injuries inflicted by a power jigsaw can be based on the study of the width of the abraded edges of the wound in order to determine the sawing velocity.

[The establishment of the fact of the application of an electric circular saw with the high-speed reciprocating motion of the blade].

This paper reports a case of forensic medical expertise of an unintentional (accidental) injury inflicted by an electric circular saw with the high-speed reciprocating motion of the blade (jigsaw) under conditions of human operational activities.

[Forensic medical characteristic of sawed injuries inflicted to the long tubular bones by a power jigsaw].

The main aspects of investigations devoted to forensic medical characteristic of sawed injuries inflicted to the long tubular bones by a power jigsaw are considered. The mathematical model has been developed making it possible to determine the frequency of backward and forward movements of the jigsaw blade from the morphological features of the injuries to long tubular bones of man and to estimate the sawing rate for the further identification of the instrument of crime.

[The use of an electric fretsaw for corpse dismemberment and concealment of a crime].

The authors present an example of forensic medical expertise of the application of a mechanical sawing instrument, in which the reciprocating motion of the cutting edge with respect to the object is guided by the electric motor (electric fretsaw), for the purpose of corpse dismemberment and concealment of a crime.

[Characteristics of stab wounds inflicted by knives with the gear-sharpened blade].

The authors present the results of an experimental study designed to estimate the damage to biological and non-biological objects inflicted by the knife blades having the gear-type sharpening. It was shown that a knife with such sharpening leaves edges of the damage of characteristic shape and outline. The results of the study testify to the expediency of further studies on the damaging action of knives considered in the present paper.

[Kinetics of immunoglobulin G transport through the multi-layer epithelial-hematic barrier of the respiratory tract].

A new class of drugs is now utilized for in vivo diagnoses and therapy of many widespread diseases. In these pharmacological and diagnostic preparations the active substance is conjugated with a vector which transports the drug to specific biological targets. Monoclonal antibodies are the most commonly used vectors: estimation of their permeability through multilayer and unilayer biomembranes is an important step in the analysis of efficiency of vector drugs.
