Bloodstain pattern analysis in a case of fatal varicose vein rupture

Rupture of a varicose vein is a rare cause of sudden death. It occurs when the failure of venous valves causes an increase in venous pressure great enough to provoke rupture of the blood vessel. When it does happen, the victim is often found surrounded by a pool of blood, and the examination of the scene can mislead the forensic team to think of violent death. Until now, the bloodstain patterns in these fatal cases have not been described. An examination of the bloodstain pattern in a case of fatal varicose vein rupture in an 84-year-old man is here reported.     

The identification of a dismembered human body: a multidisciplinary approach

A criminal case was directed to a multidisciplinary forensic team for identification, concerning a victim whose head, having two gunshot wounds, had been separated by a sharp instrument and was recovered 6 months later. The purpose of this research was to determine the sex and age of the victim for human identification. Primarily, macroscopic examination of the skull, tooth, and DNA analysis was conducted for sex determination. A rough assessment of age was made from the skull based on anthropological findings, however a more definitive result of age estimation was determined utilizing dental morphology. The dental data showed an age range of 32-37 from the mineral examination and the formulation of microscopic measurements. The results obtained from the skull and dental analysis matched with the physical characteristics of the victim's body, the known personal data of this person, and with the superposition of the photos gathered by a formal request. Besides, the result of DNA profiling of the victim showed male gender and direct relationship with the victim's presumed wife and daughter. Generally, research on human identification consists of sex and age determination. The sex characteristics can be precisely proved from DNA tests. However, age can be estimated by skeletal, and dental analysis. In this case the performed sex and age analysis lead the research to the selective matching of the missing person's identity.     

Partial Agonist Therapy in Schizophrenia: Relevance to Diminished Criminal Responsibility

Abstract: Pathological gambling (PG), classified in the DSM‐IV among impulse control disorders, is defined as inappropriate, persistent gaming for money with serious personal, family, and social consequences. Offenses are frequently committed to obtain money for gambling. Pathological gambling, a planned and structured behavioral disorder, has often been described as a complication of dopamine agonist treatment in patients with Parkinson’s disease. It has never been described in patients with schizophrenia receiving dopamine agonists. We present two patients with schizophrenia, previously treated with antipsychotic drugs without any suggestion of PG, who a short time after starting aripiprazole, a dopamine partial agonist, developed PG and criminal behavior, which totally resolved when aripiprazole was discontinued. Based on recent advances in research on PG and adverse drug reactions to dopamine agonists in Parkinson’s disease, we postulate a link between aripiprazole and PG in both our patients with schizophrenia and raise the question of criminal responsibility.     

Contribution à une analyse narrative de la théorie institutionnelle

Conclusion Que faut-il penser de la co-existence de trois modèles différents pour interpréter l'élément central de la théorie institutionnelle de MacCormick? Cette pluralité de modèles n'est source de perturbations que pour ceux qui tiennent à défendre l'idée selon laquelle il n'y a qu'une seule forme possible de discours juridique. Dès qu'il est accepté — comme hypothèse de base — que les formes d'organisation de ce type de discours peuvent être multiples, la perspective est inversée.C'est le schéma explicatif — dit schéma narratif — qui est alors unique. Quant aux différentes variantes de la formule de MacCormick, elles représentent les altérations de cette définition en fonction de paramètres identifiables — et identifiés — comme le statut des différents actants et acteurs, la définition de l'objet de valeur final dont ils cherchent à s'emparer et les objets de valeur d'usage dont ils se servent.L'éclatement de la formule de Maccormick ne correspond alors plus à un rejet mais bien à une mise en question. Cette remise en question débouchant sur la reconnaissance de plusieurs schémas narratifs, nous devons nous demander dans quelle mesure notre perception de la phasep correspond à l'idée que s'en fait MacCormick. S'agit-il seulement de la procédure au sens juridique du mot ou de tout un ensemble d'actes permettant de persuader un destinateur comme un juge ou une administration de la coïncidence entre un parcours narratif effectif et le type idéal de parcours narratif qu'ils tirent de la lecture des normes juridiques?S'il s'agit bien de la procédure au sens juridique de ce mot, il faut alors préciser au terme de cette analyse sémio-narrative que l'ensemble des phénomènes pragmatiques — comme les interactions dans le cas d'une procédure orale — ne sont pris en compte ni par la formule de MacCormick, ni par la présente discussion mais qu'ils relèvent d'une recherche particulière sur cette dimension supplémentaire, certes compatible avec la théorie sémiotique mais pas avec la théorie institutionnelle de MacCormick. Pour conclure, nous dirons donc qu'il est possible d'intégrer certains éléments de cette dernière théorie dans un cadre plus général mais qu'elle sera vite transformée à la fois de l'intérieur par la reconnaissance d'une pluralité des formes du discours et de l'extérieur par son intégration partielle dans un schéma plus large qui vise à décrire un phénomène dans son intégralité.     

Population genetics of nine short tandem repeat loci: allele frequency distribution in a Brazilian population sample

Gene and genotype frequencies in relation to the D3S1358, vWA, FGA, TH01, TPOX, CSF1PO, D5S818, D13S317, and D7S820 loci were determined in a sample of 290 unrelated individuals (204 Caucasians and 86 mulattoes) living in the city of S?o Paulo, Brazil. The sex test Amelogenin was also performed in all subjects from our sample, revealing the expected sex in all instances. Allele frequency data obtained from the analysis of these samples were in the usual range of other population groups with similar racial background. In the sample of Caucasian individuals, panmictic proportions were ruled out in relation to TPOX and CSF1PO loci, but only in the latter was the overall frequency of heterozygotes significantly less than expected. In the sample of mulattoes, Hardy-Weinberg proportions were rejected in relation to FGA and CSF1PO loci, but in no instance were the overall numbers of heterozygotes different from the corresponding expected ones under panmixia. Taking into account all this and also the number of tests performed, the degree of genetic heterogeneity of Brazilian populations, and the critical level reached by the significant results (1% < alpha<5%), the departures from panmixia here observed can be considered to be negligible in altering significantly biologic relationship odds calculated under the assumption of random matings.     

An end to a rumour

Mardin, is a city in the southeastern part of Turkey where people from different cultures and religions have been living together peacefully for centuries. The province hosted many valuable historical constructions representing different civilizations. Kasimiye Medresse, one of the most important educational centers of its times, has a sacred value for people in Mardin. The reason is that the stain on the wall of Kasimiye Medresse is considered to be Sultan Kasim's blood. Our study aims to analyze if the stain in question is blood. Serological tests are performed by using "Kastle-Meyer" and "Luminol" reactives on the scrapped samples taken from stained and unstained parts of the wall. At the end of the analysis, the stain is turned out to be a dye made of herbal roots ending the rumour of centuries.     

Raising the Threshold,Fighting Fragmentation? Mechanical and Psychological Effects of the Legal Electoral Threshold in Belgium

Many proportional representation systems are characterised by a legal electoral threshold. Such a threshold reserves the allocation of seats for those parties that reach a minimum share of the votes. In order to fight fragmentation, a 5 per cent threshold has been introduced for both federal and regional elections in Belgium. This article seeks to explore the mechanical and psychological effects of this legal threshold after five elections. It is shown that the threshold has had limited mechanical and psychological effects on voters but some psychological effects on party elites. Moreover, while in the short term the average number of lists dropped and several pre-electoral coalitions formed, in the longer term the legal threshold has not prevented further fragmentation.
