Detection of THCCOOH in hair by MSD-NCI after HPLC clean-up

Regular consumption of cannabis can easily be detected by examination of hair for tetrahydrocannabinol, cannabinol, and cannabidiol. Although several studies have demonstrated that after contamination with smoke or treatment with THC containing shampoos THC is not detectable, or only in small traces, the detection of 11-nor-9-carboxy-delta 9-tetrahydrocannabinol (THCCOOH) should be offered to prove the consumption and metabolisation of THC. Up to now this confirmation was only available using tandem MS techniques combined with negative chemical ionisation. A new method using a normal quadrupole GC/MS is described. The lack of expensive instruments has to be paid for by a costly and time consuming extraction and clean-up. After the sample has been digested by 2 M NaOH at 95 degrees C and the neutralised liquid has been extracted with a mixture of n-hexane and ethyl acetate the dried residue is reconstituted in acetonitrile-methanol-0.01 M sulfuric acid (49:21:30, v/v/v) and the cannabinoids separated by HPLC. Each fraction is collected over 1 min. Another extraction with n-hexane-ethyl acetate is followed by evaporation, derivatisation, and GC/MS determination. The calibration with THCCOOH spiked hair led to a LOD of 0.3 pg/mg and a LOQ of 1.1 pg/mg.     

Dumping after homicide using setting in concrete and/or sealing with bricks--six case reports

Homicide with subsequent hiding of the body using setting in concrete or sealing with bricks are rarely seen forensic cases. The article describes the circumstances and findings of six cases in which bodies were encased with concrete and/or bricks. In all cases, the offenders were male, in one case together with his wife and--except for one case--the victims were related to the offender. The causes of death were heterogeneous (suffocation, blunt force, shot) and the motive mainly domestic quarrel. Setting corpses in concrete and/or sealing with bricks does not prevent smell, slows decomposition and therefore complicates the estimation of the post mortem interval.     

Neonatal freshwater drowning after birth in the bathroom

The macroscopic and microscopic findings in neonatal freshwater drowning are demonstrated on the basis of 3 exemplary cases of birth in the bathroom after concealed pregnancy. If the newborn is expelled under water and remains there until death, the lungs cannot be ventilated with air. In case of incomplete or only temporary submersion, aeration of the lungs may develop in the immediate postpartum period. The morphologic criteria of separate existence are critically discussed with respect to the presented findings.     

STR data for the 15 AmpFlSTR identifiler loci in the Western Romanian population

Allele frequencies for the 15 tetranucleotide short tandem repeat loci contained in the AmpFlSTR Identifiler kit were obtained from a population sample of 219 unrelated individuals born in the western part of Romania.     

The Persistence of Social Differentiation in the Philippine Uplands

Certain drivers of social and economic differences facilitate the reification of ethnic identity between so-called uplanders and lowlanders on Palawan Island in the Philippines. Drawing on case studies, in this paper we examine how two seemingly distinct social groups – Christian migrants and indigenous Tagbanua – use their respective positions in society to mark differences in ethnic identity and livelihoods. We then argue that as non-governmental organisations build on notions of indigeneity as a means to facilitate their programmes, they further reinforce how each group articulates difference. We demonstrate that the tendency of NGOs to construct and reify notions of indigeneity in support of land claims and conservation has in fact polarised ethnic differences and, in turn, reinforced inequality between each group. We conclude that although non-governmental organisations have tried to remedy social and economic disparities between social groups, their simplification of local ways of life reinforces stereotypes of these people and their land uses.     

High thyroglobulin (Tg) concentrations in fatal traumatic brain injuries

It is well known that under physiological conditions, the Tg molecule is the substrate for the hormones triiodothyronine and thyroxine. Its function outside the thyroid gland is unknown. Under certain pathologic conditions, an increase in Tg concentrations in the blood can occur, a phenomenon that is used in the clinical diagnosis of certain thyroid disorders. However, fatal traumatic brain injuries (TBI) can also produce a raised Tg concentration in blood. In such cases, mean (n=151) Tg concentrations of 405.8+/-353.3 ng/mL have been observed, with the values in 57% of these cases exceeding 200 ng/mL. Since it was possible to rule out specifically any thyroid disorders in these cases, the raised values may be explained by the effect of TSH in the spectrum of the "hypothalamic-pituitary-thyroid axis." This assumption has been substantiated by immunohistochemical tests for TSH and Tg. Compared with the controls (sudden unnatural deaths: Tg 23.3+/-27.6 ng/mL), the raised Tg values in the TBI cases were usually accompanied by a reduction in the intensity of immunohistochemical reactions relating to TSH and Tg. The hypophysis showed evidence of significant damage with morphologic changes such as edema, hemorrhages, and focal necrosis in association with reduced TSH levels.     

First to third nature: the rise of capitalist conservation on Palawan Island,the Philippines

The social relations and agricultural lands that rural peoples in Southeast Asia hold in common are being commodified through the converging pressures of agrarian change, conservation and capitalist development. This paper examines how broader and local processes driving agrarian differentiation have been accelerated through the revaluing of people and nature in market terms to ostensibly finance conservation through development at the Puerto Princesa Subterranean River National Park – the flagship protected area of Palawan Island, the Philippines. Drawing on the notions of ‘first’ and ‘third nature’, I show how the pace and scale of agrarian change between rural peoples has gone ‘fast forward’ with the onset of resource partitioning, objectification, commodification and, ultimately, revaluing through translocal ‘capitalist conservation’, the rise of conservation as capitalist production. I examine how the national park's valuing as a ‘common’ World Heritage has drawn major private sector investments that objectify, commodify and rearticulate the value of nature as capital that finances and merges conservation and development according to the images and ideals of the modern Philippines. The conclusion asserts that while the processes of differentiation and capitalist conservation facilitate the revaluing of nature in market terms, the overall process remains recursive, partial and context dependent.     

Natural capital must be defended: green growth as neoliberal biopolitics

ABSTRACT

This contribution addresses the growing global trend to promote ‘natural capital accounting’ (NCA) in support of environmental conservation. NCA seeks to harness the economic value of conserved nature to incentivize local resource users to forgo the opportunity costs of extractive activities. We suggest that this represents a form of neoliberal biopower/biopolitics seeking to defend life by demonstrating its ‘profitability’ and hence right to exist. While little finance actually reaches communities through this strategy, substantial funding still flows into the idea of ‘natural capital’ as the basis of improving rural livelihoods. Drawing on two cases in Southeast Asia, we show that NCA initiatives may compel some local people to value ecosystem services in financial terms, yet in most cases this perspective remains partial and fragmented in communities where such initiatives produce a range of unintended outcomes. When the envisioned environmental markets fail to develop and benefits remain largely intangible, NCA fails to meet the growing material aspirations of farmers while also offering little if any bulwark against their using forests more intensively and/or enrolling in lucrative extractive enterprise. We thus conclude that NCA in practice may become the antithesis of conservation by actually encouraging the resource extraction it intends to combat.     

The body buried twice

The authors report the case of an unusual reason for an "exhumation." A young person "exhumed" a child's body involved in a road accident because he wanted to test methods for preventing or slowing down the process of postmortem decay.     

Identification of more sequence variations in the D8S1179 locus

Routine STR-typing of 10,293 buccal swabs using different multiplex kits presented discordant D8S1179 profiles in four cases. Sequencing analysis identified a G-to-A transition upstream to the repeat, and an A-to-T transversion and a G-to-A transition downstream to the repeat. In the fourth case a four-base pair deletion downstream resulted in altered genotypes using different primer pairs. Current searching algorithms of the German DNA database are not capable of matching profiles that are divergent in only one STR-locus. Thus, to accommodate matching requirements and to avoid errors in individual genetic characterization for D8S1179, as described here, it is suggested that alternative primer pairs be used for routine genotyping as a matter of course.
