A fully validated, sensitive and specific method for the extraction and quantification of Delta(9)-tetrahydrocannabinol (THC) and 11-nor-9-carboxy-Delta(9)-THC (THC-COOH) and for the detection of 11-hydroxy-Delta(9)-THC (11-OH THC) in oral fluid, urine and whole blood is presented. Solid-phase extraction and liquid chromatography-mass spectrometry (LC-MS) technique were used, with electrospray ionization. Three ions were monitored for THC and THC-COOH and two for 11-OH THC. The compounds were quantified by selected ion recording of m/z 315.31, 329.18 and 343.16 for THC, 11-OH THC and THC-COOH, respectively, and m/z 318.27 and 346.26 for the deuterated internal standards, THC-d(3) and THC-COOH-d(3), respectively. The method proved to be precise for THC and THC-COOH both in terms of intra-day and inter-day analysis, with intra-day coefficients of variation (CV) less than 6.3, 6.6 and 6.5% for THC in saliva, urine and blood, respectively, and 6.8 and 7.7% for THC-COOH in urine and blood, respectively. Day-to-day CVs were less than 3.5, 4.9 and 11.3% for THC in saliva, urine and blood, respectively, and 6.2 and 6.4% for THC-COOH in urine and blood, respectively. Limits of detection (LOD) were 2 ng/mL for THC in oral fluid and 0.5 ng/mL for THC and THC-COOH and 20 ng/mL for 11-OH THC, in urine and blood. Calibration curves showed a linear relationship for THC and THC-COOH in all samples (r(2)>0.999) within the range investigated. The procedure presented here has high specificity, selectivity and sensitivity. It can be regarded as an alternative method to GC-MS for the confirmation of positive immunoassay test results, and can be used as a suitable analytical tool for the quantification of THC and THC-COOH in oral fluid, urine and/or blood samples. 相似文献

Angola is located in the African continent, in the area of southern Africa and has a population of approximately 14 million inhabitants. The Angola population has origin from Occidental and Southern Bantu people that came from the great lakes region, creating the most ever known African migration of our days.Allele frequencies for the 15 STRs loci in the AmpFlSTR Identifiler kit (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, HUMTH01, D13S317, D16S539, D2S1338, D19S433, HUMVWA, TPOX, D18S51, D5S818, HUMFIBRA/FGA and including the segment of the X-Y homologous gene amelogenin) were studied for Angola population.The genotype frequency of the 15 STR loci showed no significant deviations from Hardy–Weinberg equilibrium expectations and great values for the combined power of discrimination and combined power of a priori exclusion validate the application of these markers in forensic genetics. Comparative analyses between Angola population data and other relevant population database from Africa, Europe and American are presented. 相似文献

The paper develops a model of crime reporting based on an economic approach. It identifies the principal costs and benefits
of reporting from the victim’s perspective, taking account of insurance provision and the risk of intimidation by an offender.
It shows how a victim might use backward induction to infer a rational reporting strategy. The recording of crime by the police
is a process that relies on victim reports, and is thus influenced by the reporting decisions made by victims. The paper uses
empirical evidence from the British Crime Survey and from the International Crime Victims Survey to explore the hypotheses
generated by the model. It finds support for the suggestion that the propensity to report a crime increases with the size
of the loss entailed. The paper also explores the implications of the findings for the estimation of the costs of crime. Reporting
and intimidation costs are generally excluded from bottom-up estimates of costs, an omission that may be quite serious in
the context of offences such as domestic violence. 相似文献

The link between business cycles and the democratic politicalsystem has long been recognized by economists. However, thedeterminants of political business cycles are not well understood.We discuss several institutional and behavioral determinants ofthose cycles, such as revolving-door appointments, term limits andpreferences of the incumbent politician, electorate and businesscommunity concerning the intertemporal pattern of publicexpenditure. We show how they affect the cycle's amplitude in thecontext of a rational-expectations model. 相似文献

The duty-of-care requirement cannot be used anymore as the touchstone to differentiate negligence from strict liability because
it can be found in many forms of the latter. Duty of care is smuggled into strict liability hidden under the scope of liability
requirement (traditionally called “proximate causation”). As far as the scope of liability requirement is common to negligence
and to many forms of strict liability, there is a fairly large common ground to both liability rules, and consequently the
marginal Hand formula is applied to both rules. Indeed, under a negligence rule, the marginal Hand formula is applied twice:
first to assess whether or not the defendant did breach his or her duty of care, and, second, to delimit whether or not the
defendant’s behavior was a proximate cause of the harm suffered by the victim. However, under a strict liability rule, the
Hand formula is applied only once when the proximate causation question is raised. Traditional law and economics analysis
has almost always taken the normative question raised by the causation requirement as given, which is a potential major problem
due to the importance of scope of liability or proximate causation in legal practice. Defining the scope of liability, that
is to say, the boundaries of the pool of potential defendants, is the basic legal policy decision for each and every liability
rule. In the normative model presented in this paper, the government first chooses efficient scope of liability, and given
the scope of liability, the government then decides the liability rule and damages that guarantee efficient precaution. In
the article, most known scope of liability rationales developed by both common law and civil law systems are discussed in
order to show the substantial common ground between negligence and strict liability. 相似文献

Tianeptine (Stablon®), although structurally similar to tricyclic antidepressants, acts by enhancing the reuptake of serotonin. A fatal case is presented involving a 26-year-old man, found lying in bed with a “mushroom of foam” around his mouth. Empty blister packs of Stablon® and a suicide note were found next to the body. A liquid–liquid extraction procedure with n-hexane: ethyl acetate and n-hexane: 2-propanol, followed by LC-DAD-MS analysis, using positive mode electrospray ionization was performed. The detection limit was 0.001 μg/mL. The toxicological results revealed the following tianeptine concentrations in the post-mortem samples: blood 5.1 μg/mL; urine 2.0 μg/mL; liver 23 μg/g; stomach contents 22 mg. Femoral blood analyses also revealed an ethanol concentration of 0.53 g/L. The present method was also developed and validated for the other post-mortem specimens, since no previous published data had confirmed the post-mortem distribution of tianeptine. The absence of other suitable direct causes of death (macroscopic or histological) and the positive results achieved with the toxicological analysis led the pathologist to rule that death was due to an intoxication caused by the suicidal ingestion of tianeptine in combination with alcohol. 相似文献

Mandatory prosecution is inefficient according to legal economists. We argue that when prosecutors are fairly insulated from their performance or are highly risk-averse mandatory prosecution is better than selective prosecution. This result has important implications for comparative law. We use our findings to provide a positive explanation for the stylized fact that mandatory prosecution generally prevails in civil law jurisdictions whereas selective prosecution is typical of common law jurisdictions. 相似文献
