Money laundering: some facts

This paper tackles the quite difficult topic of money laundering. After defining money laundering, and after explaining the three stages (steps), placement, layering and integration, the paper tries a quantification and estimation of the volume and development of money laundering activities. Besides it shows national and international measurements to fight money laundering and various effects on macroeconomics. The overall turnover in organized crime for example had a value of 800 billion USD in 2001 and increased to 1.700 billion USD in 2007. These figures are very preliminary with a quite large error, but give a clear indication how important money laundering and the turnover of organized crime is nowadays.

The evolution of DNA databases--recommendations for new European STR loci

Following a recent meeting by the ENFSI and EDNAP groups on the 4-5 April, 2005, in Glasgow, UK, it was unanimously agreed that the process of standardization within Europe should take account of recent work that unequivocally demonstrated that chance of obtaining a result from a degraded sample was increased when small amplicons (mini-STRs) were analysed. Consequently, it was recommended that existing multiplexes are re-engineered to enable small amplicon detection, and that three new mini-STR loci with alleles <130 bp (D10S1248, D14S1434 and D22S1045) are adopted as universal. This will increase the number of European standard Interpol loci from 7 to 10.     

Validation and casework testing of the BioPlex-11 for STR typing of telogen hair roots

A new STR typing strategy has been developed allowing the simultaneous amplification and subsequent analysis of 11 polymorphic systems with amplicon sizes smaller than 270bp. The multiplex amplification reaction includes six STR loci from the European standard set of loci (ESS) for DNA databases (D3S1358, D8S1179, D21S11, THO1, FGA and VWA) as well as four additional STR systems selected for their robustness (D2S1338, D12S391, TPOX and D5S818) together with the sex-specific locus amelogenin. After PCR amplification, the multiplex reaction is splitted into two sets of STR multiplexes by using biotin labelled primers only for one set. Using streptavidin-coated Sepharose beads five STR systems are separated from the other six systems prior to being analysed in two different runs on a capillary gel electrophoresis instrument. The multiplex system was developed and tested especially for the use in forensic casework if only limited amounts or highly degraded DNA is available, for instance, when isolated from telogen hair roots.     

Development of a pentaplex X-chromosomal short tandem repeat typing system and population genetic studies

Quadruplex and pentaplex systems for polymerase chain reaction amplification of X-chromosomal short tandem repeats DXS101, HPRTB, DXS8377, DXS981 (STRX1) and DXS6789 were developed for automated profiling of liquid and membrane-bound DNA samples. Chinese, Japanese and Thai populations were typed using a quadruplex system, while German and Philippine populations were analyzed using a five-locus system. Out of 88 meioses studied in Philippine family samples at each locus, a possible one repeat deletion (allele 51 to 50) at DXS8377 was observed in a father-daughter pair. Exact tests performed on genotype data from females in the Philippine, German and Thai populations indicated that these groups conform to Hardy-Weinberg equilibrium. Exact tests for population differentiation indicate significant variations in allele distributions, particularly at loci DXS101, DXS981 and DXS6789. Considered individually, DXS8377 was the most polymorphic and HPRTB the least polymorphic locus in these five populations. When the forensic efficiency of the quadruplex system was calculated, the combined power of discrimination among males (PD(M)) was no lower than 0.998, while among females the combined PD(F) was at least 0.9999 in all populations. The combined power of paternity exclusion was a minimum of 0.998 in trio cases and 0.98 in motherless cases. The addition of locus DXS6789 to the German and Philippine population databases using a pentaplex increased the forensic efficiency of the analysis system.
