A new method for determination of lysergic acid diethylamide (LSD) in body fluids by high-performance liquid chromatography and fluorescence detection was developed based on previously published methods. The new method is suitable for confirmation of samples tested positive by immunoassay, avoiding loss of LSD by absorption to surfaces. The reduced loss of LSD results in improved sensitivity. This is achieved by adding ethylene glycol to the samples, which cover glass surfaces. This principle can similarly be used to improve analysis of other drugs. Body fluids for analysis included urine and whole blood. An internal standard was applied for quantification of LSD. The new method offers satisfying precision data and has a detection limit of less than 0.05 ng/nL. 相似文献

Ethical principles are often presented as universal, immutable rules. However, when conducting research with ethnic minority
groups, such as Asian Americans and immigrants, ethical issues need to be placed within a sociocultural context as ethical
responses are filtered through the specific value orientations and belief systems of the ethnic group under study. Further,
when the group is a marginalized population, power dynamics complicate ethical principles of autonomy. The complexities are
further accentuated with sensitive topics such as intimate violence or domestic violence. Consequently, ethical questions
about autonomy, informed consent, confidentiality, limits to confidentiality, and protecting participants’ safety and reducing
distress need to be at the forefront when planning intimate violence research. An overview of sociocultural context of Western
biomedical ethics is presented and specific ethical issues that emerge when conducting intimate violence are discussed. 相似文献

This article examines cross-border integration at the sub-state level in the frame of a European Grouping of Territorial Cooperation (EGTC). The EGTC is a supranational and directly applicable EU legal instrument that regulates the creation of cross-border ‘associations' with legal personality between public authorities. Thus, it represents a policy tool that can have an effect on the institutional frame of cross-border cooperation and potentially enhance cross-border institutional integration at the sub-state level. The aim of this article is to examine the potential effect of this EU instrument on cross-border institutional integration by studying the institutional architecture of selected EGTCs. This is done on the basis of an analytical grid that defines elements of a possible integration process based on an institutional-oriented approach. This analytical grid is applied to four case studies: the Eurométropole Lille-Kortrijk-Tournai, the EGTC Ister-Granum, the Pyrenees-Mediterranean Euroregion and the European Region Tyrol-South Tyrol-Trentino. The empirical analysis shows that despite the considerable improvement of the legal basis for cooperation, the possible effect of the EGTC for further institutional cross-border integration is still rather limited due to a narrow design of institutions and a low level of actor involvement. 相似文献
