The Frequency of Cranial Base Fractures in Lethal Head Trauma

The interpretation of cranial base injuries has never been investigated from a purely anthropological perspective. Very little exists in forensic literature in order to interpret the significance of cranial base fractures. We analyzed 296 cases of deaths due to skull–brain injuries. The frequency of vault fractures was 75.7% and that of base fractures was 91.9%. We observed the distribution of cases of death according to manner of death and manner of injury and number of fossae involved. These observations were analytically compared to different variables (age, sex, manner of injury, and mode of injury). The study presented the proportion of base fractures associated with vault fractures, and the frequency of absence of base fracture in subjects with no vault fractures. Interesting associations of base fractures to age and manner of death are shown.     

From a threatening “Muslim migrant” back to the conspiring “West:” race,religion, and nationhood on Russian television during Putin’s third presidency

This article analyzes official discourse of the nation during Vladimir Putin’s third presidency, as reflected in Russian television coverage of Islam and migration. It argues that the replacement of earlier deliberately ambiguous definitions of Russian nationhood with clearly framed exclusive visions reflects the change in the regime’s legitimation strategy from one based on economic performance to one based on its security record. In this context, the systematic promotion of Russian ethno-nationalism for the purpose of achieving the regime’s general stability began not at the time of Crimea’s annexation, as it is often assumed, but at the time of Putin’s re-election amidst public protests in 2012. The goal of representing the authorities as attentive to public grievances in a society where opinion polls register high levels of xenophobia has prompted state-controlled broadcasters to use ethnoracial definitions of the nation that they had previously avoided. The media campaigns analyzed here also reflect abrupt changes in the precise identity of Russia’s main Others. Such instrumentally adopted sharp discursive swings are unlikely to constitute an appropriate tool for societal consensus management and for the achievement of political stability in the long term.     

Anti-immigrant mobilization in Russia's regions: local movements and framing processes

This article argues that increased anti-immigrant mobilization (the targeting of ethnic migrants to limit their rights and/or promote their resettlement) in Russia's regions is a consequence of local social movements adopting an anti-immigrant frame as part of their efforts to promote recruitment, acquire resources, and advance their movement's particular cause. Using the cases of Sverdlovsk's Gorod Bez Narkotikov (City Without Drugs) and Krasnodar's Cossack groups, it develops the argument and demonstrates specific ways in which an anti-immigrant frame is taken up by local movements. As a complement to existing studies of anti-immigrant sentiment or far right ideology, these cases highlight the practical politics of mobilizing support for anti-immigration causes in contemporary Russia.

Evaluation of the Photodegradation of Crystal Violet upon Light Exposure by Mass Spectrometric and Spectroscopic Methods

Abstract: Crystal violet is a very common dye in ballpoint ink. Recent research suggests that the degradation of triarylmethane dyes gives an indication of the age of a ballpoint pen entry on a document. The main problem for the quantitative evaluation of the degradation is that it is highly dependent on the exposure to light. Moreover additional factors, such as additives and substrate play an important role in this process. The aim of this work is to compare the degradation pathways of the pure dye in water and ethanol upon exposure to xenon light by UV/VIS spectrophotometry and laser desorption ionization. Significant differences have been observed in the products and the kinetics of the degradation. N-demethylation, an expected decomposition process, was found to take place only in aqueous solution and kinetics calculations showed that the degradation occurred 2.5 times faster in ethanol compared to water. The degradation of crystal violet in inks from four ballpoint pens on paper was also studied for entries made over 2–3 years. It was observed that degradation reactions were quenched by the presence of another dye due to competitive absorption. It was also observed that the thickness of a stroke (concentration of ink) influenced the degradation process. In the absence of light only one ballpoint pen showed slight degradation. A better understanding of the influence of the paper, ink composition, and storage conditions is necessary to interpret correctly the age of an ink based on the degradation of dyes.     

Selective culturing and genus-specific PCR detection for identification of Aeromonas in tissue samples to assist the medico-legal diagnosis of death by drowning

The detection of autochthonous aquatic bacteria in tissue samples from drowning cases is increasingly considered as an alternative approach to assist the medico-legal diagnosis of death by drowning. Bacteria belonging to the genus Aeromonas may be suitable candidates for this application as they are ubiquitous in natural aquatic environments but are generally not part of the human microbiota. The research aims of this study were (i) to develop a sensitive, specific and rapid screening and confirmation method for Aeromonas species in tissue samples and (ii) to evaluate aseptic sternal puncture as a post-mortem sample technique and bone marrow as an alternative matrix to provide evidence of death by drowning. The presence of Aeromonas in tissue samples was verified by cultivation using the selective media Ampicillin Dextrin Agar (ADA) and Ryan's Aeromonas Medium. The use of ADA medium was found most optimal for the sensitive, inexpensive and quick detection of aeromonads in human tissue samples. Positive culture plates were confirmed by harvesting all colonies for DNA extraction and subsequent PCR amplification using Aeromonas genus-specific primers. Aeromonads were detected in lung swab, blood and bone marrow of drowned bodies (n=3), but were negative in these three matrices for all negative controls (n=90) tested. Bone marrow proved to be a suitable alternative matrix and can be sampled post-mortem by an aseptic sternal puncture. In conclusion, this study confirms previous indications that aeromonads in cultures from blood of water bodies can be considered a potential marker for drowning. Given the fact that the number of immersed bodies (drowned and non-drowned) included in this study is statistically not significant, however, more tissue samples need to be investigated to confirm the validity of these methods to aid the diagnosis of death by wet drowning.
