When cocaine is smoked, methylecgonidine (anhydroecgonine methyl ester) is also consumed as a pyrolytic product. Methylecgonidine, on incubation with human liver homogenate, was metabolized to a stable compound, ecgonidine. The compound was also formed when methylecgonidine was exposed to a urine pH > or = 8.0. Ecgonidine is a zwitterion and highly water(More)
Seventy-four urine specimens previously found to contain lysergic acid diethylamide (LSD) by gas chromatography-mass spectrometry (GC-MS) were analyzed by a new procedure for the LSD metabolite 2-oxo-3-hydroxy-LSD (O-H-LSD) using a Finnigan LC-MS-MS system. This procedure proved to be less complex, shorter to perform and provides cleaner chromatographic(More)
During periodate degradation of interfering ephedrine, pseudoephedrine, and phenylpropanolamine in the extraction of methamphetamine from urine, it was observed that a small amount of methamphetamine was demethylated to amphetamine. although all three interfering phenylpropanolamines could be degraded by periodate at pH 5.2 and above, this(More)
Radioiodinated serum albumin has been used as a blood marker to define and quantitate physiological volumes for 12 organs and tissue types. The concentration of gallium-67 in "blood-free" tissues of rats was also determined at various times after intravenous administration. Tissues were divided into two kinetically distinguishable types based on reported(More)
Queer defies categorization and resists preset developmental trajectories. Practices of queering identities emerged near the end of the twentieth century as ways of resisting normalizing networks of power/knowledge. But how effective are queer practices at resisting networks of power/knowledge (including disciplines) that are not primarily normalizing in(More)
