Correlations on radioimmunoassay, fluorescence polarization immunoassay, and enzyme immunoassay of cannabis metabolites with gas chromatography/mass spectrometry analysis of 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in urine specimens.

Results obtained from three commercial immunoassay kits, Abuscreen, TDx, and EMIT, commonly used for the initial test of urine cannabinoids (and metabolites) were correlated with the 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (9-THC-COOH) concentration as determined by GC/MS. Correlation coefficients obtained based on 26 (out of 1359 total sample population) highly relevant samples, are 0.601 and 0.438 for Abuscreen and TDx. Correlation coefficients obtained from a parallel study on a different set of 47 (out of 5070 total sample population) highly relevant specimens are 0.658 and 0.575 for Abuscreen and Emit. The immunoassay concentration levels, that correspond to the commonly used 15 ng/ml GC/MS cutoff value for 9-THC-COOH, as calculated from the regression equations are 82 ng/ml and 75 ng/ml for TDx and EMIT and 120 ng/ml and 72 ng/ml for Abuscreen manufactured at two different time periods. The difference of these calculated corresponding concentrations provides quantitative evidence of the reagent specificity differences.     

A novel histological technique for distinguishing between epithelial cells in forensic casework

There are a number of forensic cases in which the identification of the epithelial cell type from which DNA originated would provide important probative evidence. This study aimed to develop a technique using histological staining of fixed cells to distinguish between skin, buccal and vaginal epithelium. First, 11 different stains were screened on formalin-fixed, wax-embedded cells from five women. Samples were analysed qualitatively by examining staining patterns (colour) and morphology (absence or presence of nuclei). Three of the staining methods – Dane's, Csaba's and Ayoub-Shklar – were successful in distinguishing skin epithelial cells from buccal and vaginal. Second, cells were smeared directly onto slides, fixed with one of five fixatives and stained with one of the three stains mentioned above. Methanol fixation, coupled with the Dane's staining method, specific to keratin, was the only technique that distinguished between all three cell types. Skin cells stained magenta, red and orange and lacked nuclei; buccal cells stained predominantly orange–pink with red nuclei; while vaginal cells stained bright orange with orange nuclei and a blue extracellular hue. This staining pattern in vaginal cells was consistent in samples collected from 50 women aged between 18 and 67. Identification of cell type from unlabelled micrographs by 10 trained observers showed a mean success rate of 95%. The results of this study demonstrate that histological staining may provide forensic scientists with a technique for distinguishing between skin, buccal and vaginal epithelial cells and thus would enable more conclusive analyses when investigating sexual assault cases.     

Power Politics and Wars without States

In order to evaluate the applicability of power politics theories of war and international stability to interactions among nonstate actors, I test hypotheses from power transition theory and from neorealist arguments about systemic polarity against the behavior of 20 state and nonstate actors in nineteenth‐century South America. I find considerable support for two of the three hypotheses tested and conclude that existing IR theory has more explanatory power within the empirical domain of nonstate relations than critics of such theory claim.     

Looking Beyond the Bancoult Cases: International Law and the Prospect of Resettling the Chagos Islands

During the 1960s, the US government entered into an agreementwith the UK government to construct a military facility in theChagos Archipelago. The UK government excised the Archipelagofrom the colony of Mauritius and created the British IndianOcean Territory (BIOT). Diego Garcia was transferred to theUnited States and the indigenous people of the entire Archipelagowere secretly banished. This process led to their chronic impoverishment.In the Bancoult cases, the English courts held the exile tobe unlawful and that the Chagossian people possess a publiclaw right of abode in the Chagos Islands. This article examineswhether international law can facilitate the resettlement tothe Chagos Islands via recognition of BIOT's non-self-governingstatus. It also explores the prospect of securing compensationfor the loss of ancestral lands by reference to existing andevolving international standards on indigenous rights.
