The EMIT d.a.u. cannabinoid assay of methanolic extracts of blood was found to be usable as a screening method in cases of suspected impairment by cannabis, when delta-9-tetrahydrocannabinol (THC) was analysed in the subsequent assay. A prerequisite is that the blood sample is taken some time after cannabis smoking. When a cut-off limit corresponding to 50 nM delta-9-tetrahydrocannabinol carboxylic acid (17 ng/ml) was used, 86% of the EMIT positive blood samples contained THC concentrations above the cut-off limit of 1 nM (0.3 ng/ml). A high EMIT result gave a high probability of finding a high THC concentration in the subsequent confirmation analysis. 相似文献

Measurement of clavicular length and circumference, and computation of clavicular robustness and length-circumference product from 724 autopsied adults of known age, sex, and body length between the ages of 15 and 96 years produced useful sex-predictive values. This predominantly North American white population contained 560 males and 164 females with intact, nondeformed clavicles. Clavicle length and circumference and particularly their product have been found useful in sexing, but robustness as a single trait has not. Despite a significant overlap of male and female values, the use of single cutoff values allowed correct sex assignment of up to 93% of the entire study population, including 94% of males and 89% of females. The ratios of body length to clavicle circumference and to clavicle length are on average greater in women than in men. The former ratio yields male predictive values greater than 95% for those individuals with ratios falling below the cutoff value of 43, whereas the latter ratio is a relatively poor sex predictor. 相似文献

The globalizing or totalizing imposition of a particular understanding of justice, fairness, or equality, as seen, for example, in Canada's single health care system, which forbids the sale of private insurance and the purchase of better basic health care, cannot be justified in general secular terms because of the following limitations: (1) the plurality of understandings of justice, fairness, and equality, and (2) the inability to establish one understanding as canonical. The secular state lacks plausible moral authority for the coercive imposition of one such account on peaceable, consenting adults. This state of affairs, with regard to the weakness of human moral epistemological powers, means that the secular state fails to have the moral authority to forbid coercively the sale and purchase of organs. It further lacks the secular, moral authority to impose equal access to organ transplantations. Assertions of such authority amount to reckless claims of fairness, and for this reason, health care policy must be set within the constraints of limited, constitutional regimes. 相似文献

The testing of oral fluid for drugs of abuse has increased significantly over recent years and is now commonplace in drug rehabilitation clinics, the workplace, prisons and custody suites. The global problem of identifying drugged drivers has also led to an increase in oral fluid testing at the roadside. The main requirements for the implementation of roadside drug testing are a rapid sample collection time, collection of a known sample volume and recovery of drugs from the collection device. We report here the development of the Cozart® DDS oral fluid collector, an oral fluid collector that combines rapid and adequate sample collection with satisfactory drug recovery. Oral fluid was collected from drug users (n = 134) and drug-free individuals (n = 137), using the Cozart® DDS oral fluid collector. The mean time for the completion of collection (full coloration of the sample presence indicator) was 34 s for drug-free individuals and 44 s for drug users. The average volume collected was 0.34 mL (n = 271). No chemical stimulant (to induce salivation) was used to achieve the collection times observed in either the drug-free or the drug-taking sample populations. Drugs were extracted from the collector using the Cozart® DDS buffer and drug recovery was determined by Cozart® enzyme immunoassays. The recovery studies showed that for amphetamine, Δ9THC, cocaine, methadone, methamphetamine, morphine and temazepam over 90% of the drug in the sample was eluted from the collector. The Cozart® DDS oral fluid collector provides a reliable mechanism for the collection of oral fluid at the roadside that achieves the rapid collection times required. 相似文献

A case of fatal poisoning due to the combined effect of alcohol and gasoline following an automobile accident is described. Toxicological analyses by means of gas chromatography and gas chromatography-mass spectrometry permitted the identification and quantitation of alcohol and several hydrocarbons in the heart blood and in the gas in the lung. Great variation was found in the estimates of blood gasoline concentration, depending on which of six constituents of gasoline was chosen for quantitation. The cause of this variation is discussed, together with the possible mechanisms leading to death. 相似文献

This article examines socioeconomic foundations of leftist politics in post-Soviet Russia. It is often argued that the reemergence of left politics is the result of contingent factors connected to transitional crises. While this is one source of strength for the left, there are two more important and enduring sources: a “socialist value culture” among a large majority of Russians, and an emerging pseudo-capitalist system that is creating “traditional” class-based and left-leaning attitudes and affiliations among particular social groups. The article examines the extent of this value culture and the emergence of these attitudes and affiliations through an analysis of statistical data and interviews conducted with Russian workers and intelligentsia figures from 1994–1997. 相似文献
