Summary: Tetramethylbenzidine-based chemical reagent test strips are commonly used in forensic science as a presumptive test for blood. The addition of a chelating agent, ethylenediaminetetraacetic acid (EDTA), improves the selectivity of the method and allows for discrimination of blood from other substances, producing consistent positive results on various surfaces. The spraying method with a 0.5 M EDTA solution and the chemical reagent test strip is the simplest and most effective approach for testing blood stains.

Summary: This study aimed to translate the Diabetes Eating Problem Survey-Revised scale (DEPS-R) into Arabic and study its psychometric properties in adolescents with T1D. The Arabic DEPS-R showed good construct validity and reliability, with a three-factor structure explaining 54.4% of the variance. A total of 30.6% of the participants were at high risk for DEBs. These results support the validity of the Arabic DEPS-R for assessment of DEBs in the T1D Arabic population.

Summary: This survey presents a study on the stable isotope profiles of traditional and novel precursors and pre-precursors used for the synthesis of MDA and MDMA. The results show greater variation in isotope profiles than previously reported, indicating potential for comparing and differentiating precursors used in the production of these drugs. Stable isotope profiling may also allow for the grouping or discrimination of MDA and MDMA when synthesized from these alternative chemicals.

Summary: This study investigated isotopic fractionation during the production of MDMA from the precursor helional, as well as during the HCl salt precipitation of MDMA. Variations in isotopes such as H-2, O-18, and N-15 were observed at different stages. Batch-to-batch differences in MDMA samples can be identified based on isotopic changes.

Summary: This study investigated variations in delta C-13 and delta N-15 values of nitrogen sources used in the production of ATS, with a focus on nitromethane and hydroxylamine.HCl. The study found significantly expanded delta N-15 values for nitromethane and hydroxylamine.HCl, providing a useful tool for comparing ATS. Consistent delta N-15 fractionation was observed for hydroxylamine.HCl synthesized from nitromethane.

Summary: This study analyzed the residues from four archaeological ceramic sherds to determine the contents and probable functions of the original vessels. The analysis revealed significant differences in the residues, reflecting variations in decoration, manufacture, and ceramic typologies. One vessel contained residue indicative of oils, another had residues consistent with scented materials or medicinal contents, a third probably held medicinal material, and the fourth sherd suggested it may have held chemicals or explosive ingredients. This residue analysis provides insights into luxury items, medicines, technology, and trade in medieval Jerusalem.

Summary: This study investigates the stable isotopic ratios of MDA synthesized from the alternative precursor helional. It was found that significant fractionation of hydrogen, nitrogen, and oxygen isotopes occurred during the synthesis process. This suggests that tactical intelligence can be gained from analyzing the isotopic composition variations of MDA.

Summary: In forensic crime scene investigations, the analysis of blood-stained soil is challenging due to the presence of inhibitors that limit the extraction and amplification of DNA. This study explored extraction methods from ancient DNA and environmental DNA fields to determine the most effective technique. The addition of a pre-treatment step prior to DNA profiling procedures was found to be beneficial.

Summary: This study analyzed collected DNA samples and found that if a DNA profile matches the evidence, the owner of the firearm is likely to be the contributor of the DNA. Additionally, most samples had a high likelihood ratio, indicating that one contributor accounted for the majority of the DNA profile. These data help DNA examiners to better explain the evidence in a courtroom setting.

Summary: The functional study of ground stone artefacts and the analysis of charred plant remains demonstrate the significant role of plant foods in the diets of Aboriginal Australians throughout all occupation phases at the Pleistocene-aged archaeological site of Madjedbebe. Technological studies combined with biochemical testing and GC-MS analysis reveal that the three sandstone grinding stones were used for plant processing, with one also used for animal tissue processing, suggesting a multi-functional use of the tools.

Summary: Chemical treatment of skeletal remains can reduce overall DNA quality and quantity but has no significant impact on stable isotope ratio analysis. Examination of treated and untreated human remains through histological and stable isotope analysis reveals that treated remains exhibit better preservation compared to untreated remains. Stable isotope ratio analysis is viable for both treated and untreated remains, regardless of their origin.

Summary: This paper presents the outcomes of a microcontextual geoarchaeological study conducted on earthen dwellings from the Early Iron Age village of Cerro de San Vicente. The study employed soil micromorphology, lipid biomarker analysis, XRD, and XRF analyses to investigate various aspects of the dwellings, including construction materials, site formation processes, and daily life practices. The results have shed light on the construction layers, floor use, maintenance, repaving, periods of abandonment and decay, and the presence of lipid biomarkers associated with dwelling functionality. The study significantly contributes to our understanding of ancient construction practices and the utilization of domestic spaces during the Early Iron Age.
