A more sensitive modification of the zinc test for seminal traces suitable for stable test paper strips.

A more sensitive modification of the zinc test for semen has been developed, which can be used either as a solution or incorporated into test papers. The latter retain their sensitivity for at least 3 months.     

New occupations,old demands: The public regulation of paraprofessionals

Like doctors, lawyers, and architects before them, many new paraprofessionals occupations are rapidly being defined and regulated, raising the time-worn questions regarding the virtues of free labor markets versus those of regulated labor markets. The trend to regulation is growing rapidly as the paraprofessionals increase in number. The new regulation may improve the quality of services that paraprofessionals provide. But the costs threaten to exceed the benefits. There are less costly ways to deal with the problems that have given rise to the demands for regulation. The success of these demands is due in part to inadequate consideration of their implications.     

The Open Method of Coordination in the New Member States—the Perspectives for its Use as a Tool of Soft Law

Abstract:   The open method of coordination (OMC) has introduced a shift with the traditional legal instruments set up by the Treaty. Its introduction was initially supposed to favour more 'flexibility' and 'openness' in the community legal order. After a presentation of the OMC, this article intends to provide an assessment of the OMC's implementation in the ten new Member States. It displays that the OMC is sometimes far from his initial purposes, and in consequence needs to a certain extend, to adapt some of the guidelines and to clarify its legal bases. It concludes with a critical appraisal of the use of the OMC as itself, which should be imbricated in the community.

A single-column procedure on Bond Elut Certify for systematic toxicological analysis of drugs in plasma and urine.

A single-column solid-phase extraction procedure was developed for the screening of acidic, neutral, and basic drugs from plasma. The recoveries of all 25 tested drugs exceeded 82%. After the plasma had been diluted with phosphate buffer (pH 6.0), the drugs were extracted using a single Bond Elut Certify column. The acidic and most of the neutral drugs were eluted by acetone/chloroform (1:1) and the basic drugs were eluted by 2% ammoniated ethyl acetate. Some neutral drugs appeared in both fractions. The two fractions were collected separately and evaporated until approximately 100 microL of solvent remained in the tube. Both fractions were analyzed separately on a gas chromatograph equipped with a wide-bore capillary column and a flame ionization detector. The procedure could also be used for urine samples.
