Developmental validation of feline, bovine, equine, and cervid quantitative PCR assays

Accurate DNA quantification is essential for optimizing DNA testing and minimizing sample consumption. Real-time quantitative polymerase chain reaction (qPCR) assays have been published for human and canine nuclear DNA, and the need for quantifying other forensically important species was evident. Following the strategy employed for the canine qPCR assay, we developed individual assays to accurately quantify feline, bovine, equine, and cervid nuclear DNA. Each TaqMan-based assay incorporates a genus-specific probe targeting the Melanocortin-1 Receptor gene and includes a piece of synthetic DNA that acts as an internal PCR control for detecting inhibition. Developmental validations were carried out following the revised guidelines of the Scientific Working Group on DNA Analysis Methods with modifications necessary for validation of nonhuman qPCR assays. All assays demonstrated the specificity, sensitivity, stability, reproducibility, accuracy, and precision required for forensic casework. The application of these assays to animal forensic DNA analysis has both conserved laboratory resources and improved genotyping results.     

Comparison of glass fragments using particle-induced X-ray emission (PIXE) spectrometry

A procedure has been developed to analyze the trace element concentrations in glass fragments using particle-induced X-ray emission (PIXE) spectrometry. This method involves using accelerated protons to excite inner-shell electronic transitions of target atoms and recording the resultant X-rays to characterize the trace element concentrations. The protocol was able to identify those glass fragments that originated from different sources based on their elemental analyses. The protocol includes specific approaches to calculating uncertainties and handling measurements below the level of detection. The results indicate that this approach has increased sensitivity for several elements with higher atomic number compared with X-ray fluorescence methods. While not as sensitive as laser-ablation or inductively coupled plasma mass spectrometry methods of dissolved samples, it is entirely nondestructive and entails a much simpler sample preparation process that may be used to presort glass fragments for more comprehensive elemental analysis. As such, the technique described may have a niche role in forensic glass analysis.     

宗教自由基本权利的肥大症——关于宗教和世界观自由与一般权利有效性请求的关系

当人们通览宗教和世界观自由的基本权利在过去十几年里的实际运用和法教义学上的发展时,很难忽略其在规范性轮廓上萎缩这一事实。这一现象由构成要件要素的发展上更多地考虑主观标准所承载,并且经由联邦宪法法院在司法判例中对有关限制问题的决断性的、限制性的判决而被强化。因此,相对于依据宗教或者世界观的动机而提起的个人的发展请求,一般的法治国规范的有效领域持续地受到限制。当相关现象的潜在冲突在德国呈现趋势性增长的时候,这样的判断就显得越发的危险。

Änderungskündigung

Für Bestandverh?ltnisse, auf die noch § 1 Abs 2 Z 4 MRG aF weiterhin anzuwenden ist (§ 49d Abs 2 MRG), gilt auch § 45 Abs 3 MRG nF wie für Mietgegenst?nde nach § 1 Abs 4 Z 1 MRG nF (weiter). Ab dem Anhebungsbegehren des Vermieters nach § 45 MRG gelten ua die §§ 18ff MRG. Nur wenn das Verlangen nach einem Erhaltungsbeitrag wegen der H?he des vereinbarten Hauptmietzinses nicht m?glich w?re, der vereinbarte Hauptmietzins aber zur Erhaltung des Hauses nicht ausreichte, k?me eine "?nderungskündigung" in Betracht. Es ist n?mlich lediglich die Einhebung eines Erhaltungsbeitrages, nicht aber eine ?nderungskündigung mit dem Ziel m?glich, den Mieter zu einer Erh?hung des Hauptmietzinses auf das angemessene Ma? zu bringen.

Real-time polymerase chain reaction quantification of canine DNA

The accurate quantification of target DNA is an important step in the short tandem repeat analysis of forensic biological samples. By utilizing quantification data to control the amount of template DNA in the polymerase chain reaction (PCR), forensic scientists can optimize testing and minimize the consumption of limited samples. The ability to identify and quantify target DNA in mixed-species samples is crucial when it may be overwhelmed by nontarget DNA, as in cases of dog attack. We evaluated two quantitative real-time PCR assays for dynamic range, species specificity, and inhibition by humic acid. While both assays proved to be highly sensitive and discriminating, the Melanocortin-1 Receptor (MC1R) gene Taqman assay had the advantages of a shorter run time, greater efficiency, and safer reagents. In its application to forensic casework, the MC1R assay has been advantageous for quantifying dog DNA in a variety of mixed-species samples and facilitating the successful profiling of individual dogs.
