Most commercially available STR amplification kits have never been fully validated for low template DNA analysis, highlighting the need for testing different PCR kits and conditions for improving single-cell profiling. Here, current strategies rely mainly on adjusting PCR cycle number and analytical threshold settings, with a strong preference for using 30 amplification cycles and thresholds at 30–150 RFU for allele detection. This study aimed to (1) determine appropriate conditions for obtaining informative profiles utilizing a dilution series, and (2) test the outcome on single cells using the DEPArray™ technology. Four routinely applied forensic STR kits were compared by using three different amplification volumes and DNA dilutions down to 3.0 pg, while two well-performing kits were used for single/pooled leucocyte and sperm cell genotyping. Besides reduced costs, the results demonstrate that a 50%–75% PCR volume reduction was beneficial for peak height evaluation. However, this was counteracted by an increased artifact generation in diluted DNA volumes. Regarding profile completeness, the advantage of volume reduction was only prominent in samples processed with Fusion 6C. For single and pooled cells, ESIFast and NGMDetect provided a solid basis for consensus profiling regarding locus failure, although locus dropouts were generally observed as stochastic events. Amplification volume of 12.5 μL was confirmed as appropriate in terms of peak heights and stutter frequencies, with increased stutter peaks being the main artifact in single-cell profiles. Limitations associated with these analyses are discussed, providing a solid foundation for further studies on low template DNA. 相似文献

CCTV surveillance systems are IoT products that can be found almost everywhere. Their digital forensic analysis often plays a key role in solving crimes. However, it is common for these devices to use proprietary file systems, which frequently hinders a complete examination. HIKVISION is a well-known manufacturer of such devices that typically ships its products with its proprietary file system. The HIKVISION file system has been analyzed before but that research has focused on the recovery of video footage. In this paper, the HIKVISION file system is being revisited regarding the log records it stores. More specifically, these log records are thoroughly examined to uncover both their structure and meaning. These unexplored pieces of evidence remain unexploited by major commercial forensic software, yet they can contain critical information for an investigation. To further assist digital forensic examiners with their analysis, a Python utility, namely the Hikvision Log Analyzer, was developed as part of this study that can automate part of the process. 相似文献

Although most DNA crime laboratories may not encounter fecal samples often, they are a familiar sample type in non‐human forensic laboratories due to their prevalence in the environment. Fecal matter can be challenging due to low numbers of nucleated cells and the presence of inhibitors that impede amplification success. Sampling location (internal vs. external), sampling quantity (10–200 mg), and various extraction protocols (silica matrix, bead beating, and clean‐up column) were evaluated to maximize DNA yield. The greatest yield of intact DNA was obtained using a modified silica matrix extraction protocol (VGL‐Fecal) on 30–50 mg of fecal matter collected from the external surface of a stool that had been dried for 24 h. This optimized sampling and extraction protocol was applied to a pilot study where DNA yield and genotyping success were evaluated. By optimizing our collection, sampling, and extraction procedures, a reliable method for maximizing the yield of canine fecal DNA was developed. 相似文献

Despite the explicit exclusion of its jurisdiction, the Court of Justice of the European Union exercises judicial control over Common Foreign and Security Policy (CFSP). This article examines and explains how the Court's extended jurisdiction contributes to the juridification, judicialisation and constitutionalisation of the EU's compound CFSP structures. It first lays the groundwork by explaining the link between constitutionalisation and democratic legitimation and setting out the Court's formal jurisdiction over CFSP under Article 40 Treaty on European Union and Articles 218(11) and 275(2) Treaty on the Functioning of the European Union. The centre piece of the article then identifies how the Court's jurisdiction has expanded since the entry into force of the Lisbon Treaty, points at additional ‘substantive’ avenues of judicial review on the basis of access to information and access to justice, and analyses the effects of the Court of Justice of the European Union's extended jurisdiction for CFSP. 相似文献

The development of forensic psychiatric risk assessments is discussed from a clinical point of view using the example of Sweden. A central task in forensic psychiatry has traditionally been to identify dangerous, mentally disordered subjects considered to be prone to commit violent acts. Over time, “dangerousness” has been reworded into “risk”. Nevertheless, such assessments have generally been based on the psychiatric factors characterising the individual patient, while group interaction, situational factors, or social and cultural circumstances, such as the availability of alcohol and drugs, have been largely overlooked. That risk assessments have a focused on people with a diagnosis of “mental disorder” and been used as grounds for coercive measures and integrity violations has somehow been accepted as a matter of course in the public and political debate. Even the basic question whether offenders with a mental disorder are really more prone to criminal recidivism than other offenders seems to have been treated light-handedly and dealt with merely by epidemiological comparisons between groups of persons with broad ranges of psychosocial vulnerability and the general population. Legal texts, instructions and guidelines from the authorities in charge are often vague and general, while actors in the judicial system seem to put their trust in psychiatric opinions. The exchange of professional opinions, general public expectations, and judicial decision processes poses a huge risk for misunderstandings based on divergent expectations and uses of terminology. 相似文献

There is no general consensus of how to handle disputes arising from open adoption agreements. Some states have statutes mandating mediation, but New York does not. This Note proposes that New York enact a statute that mandates adoptive and birth parents use mediation for disputes arising from open adoption agreements. The proposed statute provides a comprehensive approach to mediation by setting forth when mediation is appropriate and when it is not. The statute will also provide when the child's preference can be taken into consideration, and who will pay for mediation. 相似文献

In Europe, more than 50 approved cultivars of fiber hemp (Cannabis sativa L.) are in agricultural production. Their content of psychoactive tetrahydrocannabinol (THC) is legally restricted to <0.2% (%w/w in the dry, mature inflorescences). Cannabis strains with much higher THC contents are also grown, illegally or under license for drug production. Differentiation between these two groups relies on biochemical quantification of cannabinoid contents in mature floral material. For nonflowering material or tissue devoid of cannabinoids, the genetic prediction of the chemical phenotype (chemotype) provides a suitable method of distinction. Three discrete chemotypes, depending on the ratio of THC and the noneuphoric cannabidiol (CBD), can be distinguished: a “THC-predominant” type, a “CBD-predominant” type, and an intermediate chemotype. We present a systematic genetic prediction of chemotypes of 62 agricultural hemp cultivars grown in Europe. The survey reveals the presence of up to 35% BT allele-carrying individuals (representing either a THC-predominant or an intermediate chemotype) in some cultivars—which is unexpected considering the legal THC limit of 0.2% THC. The fact that 100% of the seized drug-type seeds in this study revealed at least one BT allele, reflects that plant breeding efforts have resulted in a fixation of the BT allele in recreational Cannabis. To guarantee a sincere forensic application based on a genetic chemotype prediction, we recommend not to classify material of unknown origin if the samples size is below nine genetically independent individuals. 相似文献
