This work outlines the unequivocal identification of the "ecstasy" analog, 2-chloro-4,5-methylenedioxymethylamphetamine, using combined gas chromatography/mass spectroscopy (GC/MS) and proton magnetic resonance spectroscopy (1H-NMR). This compound was identified along with 3,4-methylenedioxymethylamphetamine (MDMA) in an illicit tablet seizure, which included 26 off-white tablets. 相似文献

Blood vessels recovered with organs and intended for use in organ transplantation. Direct final rule
Food Drug Administration Health Resources Services Administration 《Federal register》2006,71(92):27606-27610
The Health Resources and Services Administration (HRSA) and the Food and Drug Administration (FDA) are amending their regulations to consider as part of an organ those blood vessels recovered with the organ that are intended for use in organ transplantation (HRSA regulation); and to exclude such blood vessels from the definition of human cells, tissues, and cellular and tissue-based products (HCT/Ps) (FDA regulation). We (HRSA and FDA) are taking this action to provide that blood vessels recovered with organs and intended for use in organ transplantation are governed by the regulations pertaining to organs. The regulation of other recovered blood vessels remains unchanged. We believe that this change will eliminate the unnecessary burden resulting from an organ procurement organization's efforts to comply with both FDA and HRSA rules with respect to blood vessels (FDA jurisdiction) and organs (HRSA jurisdiction). We are issuing these amendments directly as a final rule because they are noncontroversial, and there is little likelihood that we will receive any significant adverse comments. Elsewhere in this issue of the Federal Register, we are publishing a companion proposed rule under our usual procedures for notice and comment in the event that we receive any significant adverse comments on the direct final rule. If we receive any significant adverse comments that warrant terminating the direct final rule, we will consider such comments on the proposed rule in developing the final rule. 相似文献

The Occupational Safety and Health Administration (OSHA) through this final rule is continuing to remove and revise provisions of its standards that are outdated, duplicative, unnecessary, or inconsistent, or can be clarified or simplified by being written in plain language. The Agency completed Phase I of the Standards Improvement Project in June 1998. In this Phase II of the Standards Improvement Project, OSHA is again revising or removing a number of health provisions in its standards for general industry, shipyard employment, and construction. The Agency believes that the changes streamline and make more consistent the regulatory requirements in OSHA health and safety standards. In some cases, OSHA has made substantive revisions to requirements because they are outdated, duplicative, unnecessary, or inconsistent with more recently promulgated health standards. The Agency believes these revisions will reduce regulatory requirements for employers without reducing employee protection. 相似文献
