Desquamative interstitial pneumonia in an infant. Mimicry of sudden infant death syndrome

A 15-week-old infant girl, without a prior history of overt illness, was found dead while sleeping between her two parents. The gross examination at autopsy showed only congested lungs, and the initial diagnosis was sudden infant death (SID). On microscopic examination, a desquamative interstitial pneumonia (DIP) was observed. The widespread, patchy intraalveolar histiocytic desquamation was associated with lymphocytic infiltration of bronchiolar and aveolar walls, which together provided convincing evidence that an interstitial pneumonitis was the cause of death. A viral etiology seems most likely in view of the accompanying chronic inflammation of bronchial submucosal glands.     

A demonstration of spermatozoa on vaginal swabs after complete destruction of the vaginal cell deposits

The proteolytic enzyme, proteinase K, has been found to destroy all vaginal cells though it does not have the same effect on spermatozoa. In cases of sexual offenses, in which a swab has been used to wipe out the vagina, the female cells and their nuclei on that swab may also contain the heads of spermatozoa. After as short a time as 30 min of proteinase K treatment, the spermatozoa that had separated from the enzymatically destroyed vaginal cells were recovered. This proteinase destruction furnishes some spermatozoa with deformed heads and a somewhat greater number of isolated tails though a sufficient number of spermatozoan heads still remain for a reliable diagnosis. For detection of spermatozoa from a vaginal swab after proteinase K pretreatment, the heads of the spermatozoa are distinctly stained by Oppitz's method. Further, on prior treatment with proteinase K, the ABO blood grouping of the spermatozoa could also be determined on the vaginal swab by using the absorption-elution technique. The resistance of the spermatozoa to proteinase K is the basis for this method.     

The methodological aspects of establishing the time of death]

Methodological analysis of essence of problem concerning postmortem interval estimation is given. The authors present the most promising ways of scientific research on this problem and possibilities of practical use of results of scientific research. The general methods of postmortem interval estimation including wired-in analogy (criterial) method and methods of modelling postmortal processes (mathematical and physical) are analysed. Graph of logical structures of modes of postmortem interval estimation and means of their realization is given.     

Methods and motives: Exploring links between transnational organized crime and international terrorism

The nexus with transnational organized crime is increasingly a focus for security planners in their analyses of terror groups. Their approach is best described by the phrase “methods, not motives.” While the motives of terrorists and organized criminals remain divergent most often, our research indicates this is not always the case. For that reason, this report argues that such a general approach has become too restrictive and can be misleading since the interaction between terrorism and organized crime is growing deeper and more complex all the time. In short, the lines of separation are no longer unequivocal. The report analyzes the relationship between international organized crime and terrorism in a systematic way in order to highlight the shortcomings of the “methods, not motives” argument. In so doing, the report considers the factors that most closely correspond to crime-terror interaction and identifies those regions of developed and developing states most likely to foster such interactions. Likewise, the paper will suggest an evolutionary spectrum of crime-terror interactions that serves as a common basis for discussion of such often used terms as “nexus.” The centerpiece of the report is a groundbreaking methodology for analysts and investigators to overcome this growing complexity, identify crime-terror interactions more quickly and to assess their importance with confidence. The approach is derived from a standard intelligence analytical framework, and has already proven its utility in law enforcement investigations. The report is the product of a recently concluded and peer-reviewed 18-month NIJ sponsored research project, and includes empirical evidence drawn from numerous case studies developed in the course of the research program.

Genetic polymorphism of desialyzed alpha 2 HS-glycoprotein by ultrathin isoelectric focusing

The genetically determined polymorphism of alpha 2 HS-glycoprotein was analyzed by immunoblotting ultrathin-layer polyacrylamide gel isoelectric focusing in the pH range 4-6.5 and neuraminidase pretreated sera. In a Libyan population sample from Tripoli (n = 110) three common phenotypes, alpha 2 HSG 1-1, 2-1, and 2-2, were observed. The allele frequencies were alpha 2 HSG1 = 0.8364 and alpha 2 HSG2 = 0.1636. The theoretical exclusion rate in cases of disputed paternity is 11.8%.
