The postmortem levels of biogenic amines in cerebrospinal fluid may represent a useful tool in defining some pathological conditions; no information is available concerning the occurrence of trace amines in postmortem cerebrospinal fluid. Thus, the occurrence of octopamine, synephrine and tyramine were evaluated by using a HPLC system in 20 postmortem samples of cerebrospinal fluid (obtained from 11 males and 9 females) and their levels were compared with those of 20 living subjects (obtained from 11 males and 9 females). The results show that trace amines dramatically increase in the postmortem cerebrospinal fluid (100, 20, and 4 fold increase for tyramine, octopamine, and synephrine respectively). To our knowledge, our data represent the first time trace amines have been identified in postmortem cerebrospinal fluid and the dramatic increase observed for tyramine has the potential of becoming a new tool in forensic science for better defining the time of death. 相似文献

Short amplicon autosomal short tandem repeat (Mini-STR) assay has proved to be a highly useful tool in forensic applications, especially for highly degraded DNA samples that typically result in partial profiles and total loss of information from regular STR amplicons.In this study two new quadruplex systems were designed to get nuclear DNA profile from degraded forensic casework samples. In order to obtain PCR products less than 120 bp in size, primer pairs of eight STR markers, included in available commercially multiplex PCR kits, were redesigned and assembled in two PCR-multiplexes: D8S1179, D3S1358, TPOX, D16S539 and CSF1P0, TH01, D13S317, D5S818.After validation, these two Mini-STR quadruplex were employed in paternity testing case that involved DNA extraction from archival postmortem Bouin's fluid-fixed paraffin-embedded tissue where commercial kit yielded low success. The results obtained with the present Mini-STR PCR-multiplexes proved clearly demonstrating their usefulness in analyzing degraded DNA samples. 相似文献

Results from a collaborative exercise with proficiency testing conducted by 20 Italian laboratories on the 15 loci included in the Identifiler kit were analyzed by allele sharing methods and by standard population genetics tests. The validated database, including about 1500 subjects, was merged with that of a previous exercise conducted on nine loci, and the resulting allele frequencies, subdivided by Italian region, were published on-line. 相似文献

The present study analyses three tetranucleotide (DXS7423, DXS8378, DXS6809) and one trinucleotide (DXS7424) X-linked STRs loci in a population sample of North Italy to evaluate their efficiency in forensic applications. The four loci were also used to solve a case of deficiency paternity, in which the question was to establish whether two women were half sisters. 相似文献
