Degradation of human DNA extracted from forensic stains is, in most cases, the result of a natural process due to the exposure of the stain samples to the environment. Experiences with degraded DNA from casework samples show that every sample may exhibit different properties in this respect, and that it is difficult to systematically assess the performance of routinely used typing systems for the analysis of degraded DNA samples. Using a batch of artificially degraded DNA with an average fragment size of approx. 200 bp a collaborative exercise was carried out among 38 forensic laboratories from 17 European countries. The results were assessed according to correct allele detection, peak height and balance as well as the occurrence of artefacts. A number of common problems were identified based on these results such as strong peak imbalance in heterozygous genotypes for the larger short tandem repeat (STR) fragments after increased PCR cycle numbers, artefact signals and allelic drop-out. Based on the observations, strategies are discussed to overcome these problems. The strategies include careful balancing of the amount of template DNA and the PCR cycle numbers, the reaction volume and the amount of Taq polymerase. Furthermore, a careful evaluation of the results of the fragment analysis and of automated allele calling is necessary to identify the correct alleles and avoid artefacts. 相似文献

The report presents the case of a 33-year-old man under the primary assumption of homicide in which the court-ordered autopsy revealed death as a result of bleeding due to a spontaneous rupture of the urinary bladder. The article gives a short summary of the pathomorphological findings and their respective causes, for example the typical location of the rupture at the posterior wall and roof of the bladder and the common concomitant drunkenness. Furthermore, obligatory forensic investigations--beside the autopsy--are mentioned and discussed. 相似文献

The article summarises three fatalities after attacks by wild animals. The first case describes a 90-year-old woman who died as a result of pneumonia after a bear fell on her and caused multiple chest fractures. The second case deals with a 76-year-old woman who was hit in the middle face by the hoof of a camel and, thereafter, died of myocardial infarction. The third case describes a 27-year-old biologist who died from severe blunt trauma after an attack of a wild living elephant. The article gives a summary of typical injury patterns of selected wild animals and outlines potential reasons of death as a result of the injuries. 相似文献

In forensics, bloodstains on dark fabrics might be invisible for the naked eye. Although several visualization, presumptive, and confirmatory blood tests have been developed, all have one or more disadvantages, especially on DNA analysis. We report here the use of a visualization assay that can visually detect blood drops up to 1/20 dilution. In this assay, the fabric is placed between two wet filter papers and covered by glass surfaces on both sides. Pressure is applied on the glass surfaces in which bloodstains transfer onto the filter papers through capillary forces. Detected stains can be tested with other more sensitive presumptive blood tests performed on the filter paper. Even more, DNA analysis can be performed on the transferred bloodstains. The presented visualization assay is easy to perform, extremely cheap, requires little hands on time, and does not affect bloodstain pattern analysis. 相似文献

This paper deals with double lobbying: several bureaucratsparticipate in joint lobbying to get a high total departmental budget, butthey also engage in antagonistic lobbying to reap as high a share of thetotal budget as possible. The antagonistic lobbyingconstitutes a contest among the bureaucrats. This papercharacterizes the Nash equilibria in lobbying and shows inwhich way exogenously fixed bureaucratic incomes induce thesame or different lobbying behavior as incentive incomes. 相似文献

Abstract: In what has become known as the ‘Maastricht II’ debate the call for a European constitution plays a great part. Often it is even expected to provide the solution to Europe's democracy problem. This paper looks at the calls for a constitution and asks how far they are already met by the Treaties and what consequences fully meeting them would have for the Union and the Member States. 相似文献
