This article examines the intercultural context of issues related to genetic research on Native peoples. In particular, the article probes the disconnect between Western and indigenous concepts of property, ownership, and privacy, and examines the harms to Native peoples that may arise from unauthorized uses of blood and tissue samples or the information derived from such samples. The article concludes that existing legal and ethical frameworks are inadequate to address Native peoples' rights to their genetic resources and suggests an intercultural framework for accommodation based on theories of intergroup equality and fundamental human rights. 相似文献

Aspartic acid racemization has been found to be an accurate measure of age at death for recent forensic material. This paper examines the practicality of using acid etching of the tooth surface to extract amino acids from the enamel for racemization analysis. By serial etching of the tooth and contamination of the teeth with bovine serum albumin prior to etching, the ability of etching to remove contamination was assessed. The destructiveness of the method was visualized and quantified using micro-computed tomography (micro-CT). By bleaching the teeth and by deeper etching it was possible to obtain more consistent values. While etching had little effect on the enamel at the macroscale, it did have an impact at the microscale. The quantities of enamel removed varied depending upon the tooth morphology, but were not large. Acid etching of enamel thus appears to be a promising new method for extracting proteins for amino acid racemization age estimation noninvasively. 相似文献

The plasma cell dyscrasias are a diverse group of disorders characterized by the production of a clonal paraprotein. Sudden death is a recognized complication of the plasma cell dyscrasias, most commonly in individuals with cardiac involvement by amyloidosis. However, the current forensic literature has no reported cases in which sudden death resulted from complications of a plasma cell dyscrasia that was first diagnosed by postmortem histologic examination. We present the case of a woman whose sudden and unexpected death resulted from a seizure. Postmortem examination revealed no evidence of trauma or a grossly identifiable natural disease process that would have accounted for her death. However, microscopic and immunohistologic studies revealed a previously undiagnosed plasma cell dyscrasia, the clonality of which was determined by immunohistochemical studies for immunoglobulin light chains, that was not associated with amyloid deposition. This case elucidates a previously unrecognized cause of sudden unexpected death and illustrates the importance of microscopic studies in selected cases examined in medical examiner/coroner offices. 相似文献

Fentanyl deaths have increased with availability of transdermal patches. Interpretation of postmortem fentanyl levels may be complicated by postmortem redistribution and absorption of fentanyl from a patch. We applied an unused 100‐μg/h fentanyl patch onto the lower abdomen of a decedent with no premortem fentanyl exposure. Ocular fluid, blood, and urine were collected prior to placement, and the decedent was refrigerated for 23 h. Prior to the autopsy, urine, subcutaneous tissue under the patch, and samples from the same anatomic sites were obtained. We observed no fentanyl in any postpatch placement samples (LOD: 0.1 ng/mL for blood and vitreous fluid, 1.0 ng/mL urine, 2.0 ng/g for tissues). Although we observed no postmortem absorption of fentanyl, this was only a single case; therefore, we recommend that patches be removed after receipt of a cadaver before initiation of an autopsy, with the location of removed patch documented. 相似文献

This article reports on mortality in a cohort of 7084 English, Irish and Scottish-born convict men who were transported on 30 ships to Tasmania between 1840 and 1852. To the authors' knowledge, this is the first study of convict mortality that systematically traces the mortality of convicts after emancipation as well as under sentence. This pilot study investigates the relationship between pre-transportation characteristics, convict discipline, reactions to convict discipline, and mortality under and after sentence of the male convict population. The convict men were various in their origins but shared the experience of penal servitude under the gaze of a paper panopticon. Controlling for other factors, the authors find that the convicts were more likely to die under sentence if they were born in Scotland, London or an industrial-urban area; if they exhibited disturbed mental behaviour under sentence, such as tearing their clothes; or if they had more time in solitary confinement or more accumulated insults of their mind and body. For those who survived sentence, mortality was higher for those born in an industrial-urban area, those who had more alcohol-related offences under sentence, those with more time in solitary confinement under sentence, and those who were violent or threatened violence while under sentence. 相似文献
