Six commercial preparations of human genomic DNA were quantified using five quantification methods: UV spectrometry, SYBR-Green dye staining, slot blot hybridization with the probe D17Z1, Quantifiler™ Human DNA Quantification kit and RB1 rt-PCR. All methods measured higher DNA concentrations than expected based on the information by the manufacturers. UV spectrometry, SYBR-Green dye staining, slot blot and RB1 rt-PCR gave 39, 27, 11 and 12%, respectively, higher concentrations than expected based on the manufacturers’ information. The DNA preparations were quantified using the Quantifiler™ Human DNA Quantification kit in two experiments. The measured DNA concentrations with Quantifiler were 125 and 160% higher than expected based on the manufacturers’ information. When the Quantifiler™ human DNA standard (Raji cell line) was replaced by the commercial human DNA preparation G147A (Promega) to generate the DNA standard curve in the Quantifiler™ Human DNA Quantification kit, the DNA quantification results of the human DNA preparations were 31% higher than expected based on the manufacturers’ information. The results indicate a calibration problem with the Quantifiler™ human DNA standard for its use with the Quantifiler™ Human DNA Quantification kit. The possible reasons for the problem are discussed and a solution is suggested. The results emphasise the need for standard reference DNA material and standard methods for DNA quantification. 相似文献

Das Lissabonurteil des deutschen Bundesverfassungsgerichts hat gro?e Aufmerksamkeit erzeugt, die keineswegs auf Deutschland
beschr?nkt blieb. Der vorliegende Beitrag geht der Frage nach, ob die vom Bundesverfassungsgericht gezogenen Schlussfolgerungen
auch die Rechtslage in ?sterreich tangieren. Insbesondere stellt sich die Frage, ob eine allf?llige Gesamt?nderung der Bundesverfassung
durch den Vertrag von Lissabon neu zu diskutieren w?re. Schlie?lich behandelt der Beitrag auch die Frage, ob der Vertrag von
Lissabon zwingend eine ?nderung der parlamentarischen Mitwirkungsrechte in ?sterreich erfordert. 相似文献

Nowadays immunoassays are used for the rapid screening of drugs world-wide. Despite the fact that they are a highly valuable tool for the test of legal and illicit drugs, there is a non-negligible risk of false positive and false negative findings, and many pitfalls must be taken into account when using these tests in an uncritical manner and without valid confirmation procedures. In accordance with the committee for "problems of threshold values for medical and addictive drugs" set up by German scientific societies (in particular GTFCh, DGRM and DGVM), immunoassays are recommended as a useful tool for screening. But confirmation analysis with conclusive methods (GC/MS or LC/MS) is indispensable for valid substance identification, discrimination between active and inactive metabolites, detection of escort substances and accurate determination of concentrations in body fluids. 相似文献

The authenticity of recovered memories is a much debated issue. Surprisingly, no study has systematically looked at symptom overreporting in people claiming recovered memories of childhood sexual abuse (CSA). In a first sample we administered the Structured Inventory of Malingered Symptomatology (SIMS) to individuals who said they had recovered CSA memories (n=66), individuals who said their CSA had always been accessible (continuous CSA memory group; n=119), and controls who said they had no CSA experiences (n=83). In a second sample individuals reporting recovered (n=45) or continuous (n=45) CSA memories completed the Morel Emotional Numbing Test (MENT). Our aim was to compare these groups with regard to their tendency to overreport symptoms. The results indicate that people with recovered memories do not score higher on the SIMS and the MENT than other CSA survivors suggesting that symptom overreporting is not typical for people reporting recovered memories. 相似文献

The Council Regulation (EC) no. 1493/1999 of 17 May 1999 on the common organisation of the market in wine (Abl. L 179 dated 14/7/1999) and the GMO Wine 2000 (Annex VII A) stipulates that the labels of wine bottles have to indicate, among others, information on the sales designation of the product, the nominal volume and the alcoholic strength. The latter must not differ by more than 0.5% vol. from the alcoholic strength as established by analysis. Only when quality wines are stored in bottles for more than three years, the accepted tolerance limits are +/- 0.8% vol. The presented investigation results show that deviations have to be taken into account which may be highly relevant for forensic practice. 相似文献
