Sudden death due to unsuspected coronary vasculitis.

Coronary artery vasculitis is a well-recognized complication of polyarteritis nodosa and is occasionally seen in other forms of systemic vasculitis. However, involvement of the major epicardial coronary arteries leading to myocardial infarction and death is uncommon. Isolated coronary arteritis is even more rare. We report three cases of sudden death due to myocardial ischemia associated with arteritis of the major coronary arteries. All three decedents were previously healthy young to middle-aged men who had died suddenly after complaints of chest pain and shortness of breath. The autopsy findings and differential diagnoses are presented. Such cases are of particular interest to the medical examiner because of the sudden, unexpected nature of the deaths. An approach to the correct diagnosis is discussed.     

Development and usage of a NIST standard reference material for real time PCR quantitation of human DNA

National Institute of Standards and Technology SRM 2372 human DNA quantitation standard has been produced to support the need for a human-specific DNA quantitation standard in forensic casework and calibration of new quantitative polymerase chain reaction (qPCR) assays. The conventional DNA concentration has been assigned with one of the U.S. National Reference UV/Visible Spectrophotometers, assuming an absorbance of 1.0 at 260 nm equals 50 ng/μL of double stranded DNA. In addition, an interlaboratory study has been conducted, to verify that the SRM 2372 materials perform well in currently used DNA quantitation assays by the forensic DNA community. Each unit of SRM 2372 consists of three well-characterized DNA extracts. Component A is a single-source human male material derived from blood. Component B is a multiple-source human female material derived from blood. Component C was purchased as a purified unsheared genomic human DNA (Sigma-Aldrich Co., St. Louis, MO) obtained as a lyophilized human genomic extract and has both male and female donors. SRM 2372 is intended to enable the comparison of DNA concentration measurements across time and place. Manufacturers can use SRM 2372 to validate the values assigned to their own reference materials. Individual forensic laboratories can use SRM 2372 to validate DNA quantitation methods and to verify the assigned concentration of in-house or commercial DNA calibration standards.     

The role of certain sections of the central nervous system in the genesis of sudden death]

Hypothalamic and hippocampal lipid composition in sudden death from coronary heart disease is studied. Thin-layer chromatography was the main method of biochemical analysis. Disorders in the lipid component of hippocampal cytostructures involved mainly the cholesterol fractions. Metabolic disorders in the hypothalamus involved the phospholipid metabolism. The above-mentioned biochemical changes were paralleled by ultrastructural abnormalities. Analysis of the data demonstrates a probable metabolic basis of a central mechanism of sudden cardiac death.     

Micromorphological criteria of the early periods in craniocerebral trauma]

System of quantitative criteria for early periods of craniocerebral trauma involving short intervals (0-5 min, 0.5h, 1-2h, 3-4h, 5-6h) was developed on the basis of micromorphometric study of the brain obtained from 120 persons who died of craniocerebral trauma. High informative value of morphometric characteristics of vagus dorsal nucleus (values of neurocyte quantity, disorientation and deformity; percentage of cells without visible changes and different pathomorphologic types; excess coefficient; coefficient of correlation between volumes of neuron bodies and nuclei; nucleus volume) was determined. Optimal conditions of using quantitative criteria were outlined.

HLA DQ alpha typing of forensic specimens by amplification restriction fragment polymorphism (ARFP) analysis.

The alleles present at the HLA DQ alpha locus may be typed by either allele specific oligonucleotide (ASO) probing or by restriction mapping, referred to here as amplification restriction fragment polymorphism (ARFP) analysis. ASO typing relies upon hybridization principles, whereas ARFP typing relies upon restriction site analysis. Dot-blot ASO typings which are of doubtful interpretation may be directly checked by ARFP analysis. Aliquots of the PCR products amplified using the commercial Amplitype HLA DQ alpha system are digested with suitable restriction endonucleases. Electrophoresis, blotting and detection of biotin-labelled restriction fragments provides a sensitive and robust typing method suited to forensic analysis.     

Legislative Basics of Legal Interpretation

The main purpose of legal interpretation is to create conditions for the effective functioning of law and its components by clarifying their true content, which eliminates any doubts and ambiguities. The purpose of this article is: first, to analyze the provisions of current Ukrainian legislation for identifying the general approaches embodied in it and the principles for the implementation of legal interpretation activities by state power bodies; secondly: presentation on the basis of modern achievements and developments of legal science of the system of measures for standardization of such activity, bringing it in line with the needs of law enforcement practice. The solution of the set tasks was carried out using the method of philosophical dialectics, a system of general scientific and special scientific methods of cognition, which are based on the principles of objectivity, comprehensiveness, complexity. Based on the analysis of the normative material, it is concluded that there is no single harmonized approach in the Ukrainian legislation on the procedure for providing clarifications of the content of normative-legal acts. The authors give arguments on the need to clarify and streamline the legal interpretation activity by state bodies and propose a number of measures to achieve this goal. Based on the conducted analysis of the normative material, the authors outline the main problematic issues of the legislative definition of the basics of legal interpretation and provide specific proposals for improving the current legislation in this area.
