Study of anatomical and topographical peculiarities of the mucosal pattern on the dorsal surface of the tongue in the immediate and late postmortem periods

The authors present information about anatomical and topographical peculiarities of the patterns of the mucous membrane at the backside surface of the tongue in the immediate and late postmortem periods. The apparent dynamics of the structural changes on this surface does not exclude the possibility of using them as the criteria for personality identification within 1 month after death.     

Characteristics of morphological manifestations of anaphylactic shock in response to the administration of pharmaceutical preparations encountered in the practice of forensic medical expert-histologist

The authors report the results of a forensic medical investigation of 6 cases of death associated with the administration of pharmaceutical products documented by forensic medical experts of the Russian Centre of Forensic Medical Expertise. The results of the study are compared with the clinical data and summarized using the methods of tanatogenetic analysis. The following main clinical variants of iatrogenic anaphylactic shock (IAS) are distinguished: bronchospastic IAS (n = 1), asphyxic IAS (n = 1), hemodynamic IAS (n = 3), and combined (bronchospastic plus hemodynamic) IAS (n = 1). The signs of all these variants are described allowing for their diagnostics and differentiation diagnostics. These data can be used for the purpose of forensic medical diagnostics and elucidation of the mechanisms of tanatogenesis.     

Biometric ranging of the corpses destroyed at the site of a catastrophe in terms of gender, longitudinal and circumferencial dimensions, and the degree of subcutaneous fat distribution

The quantitative criteria for biometric ranging of destroyed corpses in terms of anatomical localization, gender, longitudinal length, trunk circumference, and the folds of subcutaneous fat are proposed. The wealth of anthropometric materials obtained in the studies of various Caucasoid populations was used to calculate the normative tables for biometric ranging of the decomposed corpses. The proposed technology excludes the subjective assessments for the purpose of such classification at the sites of catastrophes. Moreover, it promotes the accumulation of the variety of valuable information, such as the size of the collar, headwear, and footwear, clothing size and height, and portrait features, that can be used for victim identification.     

Approaches to the improvement of forensic medical expertise in the cases of sexual crimes and doubtful gender status

The authors analyzed the results of the forensic medical expertise of the cases of sexual assaults and covert sexual abuse. Special attention is given to the peculiarities of forensic-medical expertise in the cases of veneral diseases and HIV-infection, injuries to sexual organs in women and men. The specific approaches to the examination of corpses in the cases of atypical sexual behavior or a murder supposedly committed for sexual motives are considered.     

Forensic Analysis of mtDNA Haplotypes from Two Rural Communities in Haiti Reflects Their Population History

Abstract: Very little genetic data exist on Haitians, an estimated 1.2 million of whom, not including illegal immigrants, reside in the United States. The absence of genetic data on a population of this size reduces the discriminatory power of criminal and missing‐person DNA databases in the United States and Caribbean. We present a forensic population study that provides the first genetic data set for Haiti. This study uses hypervariable segment one (HVS‐1) mitochondrial DNA (mtDNA) nucleotide sequences from 291 subjects primarily from rural areas of northern and southern Haiti, where admixture would be minimal. Our results showed that the African maternal genetic component of Haitians had slightly higher West‐Central African admixture than African‐Americans and Dominicans, but considerably less than Afro‐Brazilians. These results lay the foundation for further forensic genetics studies in the Haitian population and serve as a model for forensic mtDNA identification of individuals in other isolated or rural communities.     

Diagnosis of Hemorrhagic Stroke in an Exhumed Brain After Three Years of Burial in a Deep Grave

Abstract: We present the forensic neuropathologic analysis of an exhumed decomposed brain following long‐term interment in a 50‐year‐old white woman, who had been buried for 34 months. Next of kin authorized exhumation of the body for an autopsy to determine the cause of death. The embalmed body was anatomically intact and revealed decompositional changes with mold colonies. Internal viscera showed intact histomorphology. The brain revealed diffuse congestive swelling and extracellular edema with dissecting parenchymal hemorrhage and hematoma originating from the left putamen and thalamus and extending to the left lateral ventricle. Excitotoxic neuronal injury as well as penumbric parenchymal changes was noted. Cause of death was determined to be a hypertensive cerebral parenchymal hemorrhage. This case and our previously reported case are sentinel cases, which should encourage and guide the forensic neuropathologic work‐up and investigation of causes of death in spite of long‐term burial in deep graves.     

Reducing juvenile recidivism with cognitive training and a cell phone follow-up: an evaluation of the realvictory program

The purpose of this research was to evaluate the effects of a cognitive training and cell phone intervention on the recidivism of 70 juvenile offenders. Median days to rearrest were 106 for the control group, 191 for the class-only group, and 278 for the class plus cell phone group. Using rearrest as the survival criterion, the survival ratios of the class-only and class plus cell phone groups were 2.64 and 2.94 times longer than the control group, respectively. After controlling for gender, prior arrests, and risk score, the Poisson regression indicated that the class-only and class plus cell phone groups were 51% lower in total arrests than the control group. These results suggest that cognitive training supplemented with a cell phone coach is an effective and cost-efficient intervention for reducing recidivism.     

Potential carcass enrichment of the University of Tennessee Anthropology Research Facility: A baseline survey of edaphic features

The University of Tennessee Anthropology Research Facility (ARF) is known for its unique contribution to forensic science as a site of human decomposition research. Studies conducted at ARF are integral in our understanding of the processes of human decomposition. As such, the authors are interested in the long-term effects of continuous human decomposition on the soil environment. Soil samples collected from within and outside the ARF were evaluated for moisture content, pH, organic content, total carbon and nitrogen content, and biomass by lipid-bound phosphorus, and total extracted DNA. Analyses revealed no significant differences (p<0.05) among the sampled areas within the facility, and yet demonstrated a possible trend toward increased levels of total N, Lipid-P, and water, suggesting an influx of high-quality nutrients into the ARF soil. Furthermore, elevated pH readings, presumably resulting from ammonification of the soil, were observed in areas of high decomposition. The negative control samples proved significantly different from nearly all samples collected within the facility, the exceptions being total carbon content and extractable DNA. These findings indicate that while landscape samples inside may be similar to themselves, they are dissimilar to those taken in a similar temperate forest biome with no recorded history of human decomposition.     

Forensic analysis of black coral (Order Antipatharia)

Fourier-transform infrared spectroscopy (FTIR), discriminate analysis, X-ray fluorescence spectrometry (XRF), and stereoscopic microscopy were used to separate black coral forensic evidence items from similarly appearing items manufactured from plastics, bovid keratin, and mangrove wood. In addition, novel observations were made of bromine and iodine relationships in black coral that have not been previously reported.     

Beyond town and gown: university economic engagement and the legacy of the urban crisis

University-driven land development and research into the amelioration of social problems are examples of the wider dimensions of economic engagement by large American research universities in metropolitan settings since 1949, and both dimensions are strongly conditioned by the experiences of universities and surrounding neighborhoods during the “urban crisis” of the 1960s. The rise of the modern American research university between 1950 and 1980 coincided with the economic decline of large American cities and the slide of their poorest neighborhoods into severe socioeconomic distress. The elite identification of the university as a force for economic and social change was a direct response to these urban upheavals, and the dynamics of its new role were fueled by the presumptions of postwar consensus liberalism. The urban crisis had an effect on town-gown relations that endured into the early twenty-first century, not least because it made local governments and universities allies rather than adversaries. Countering definitions of the role the university should take in economic development have arisen from a “town” comprised not of elected officials, but of community members from both within and outside of the university. The long shadow of urban crisis attests to the historical contingency of town-gown interactions and the usefulness of historical, case-based approaches to understanding the role of universities in urban and metropolitan economies.
