0964 Sleep Paralysis and Hypnogogic/Hypnopompic Hallucinations: Prevalence in Student Athletes and Relationship to Depressive Symptoms

April 27, 2018 S. Liu, A. Athey, William D. S. Killgore et al.

Student athletes are known to demonstrate high rates of common sleep symptoms. Less common sleep symptoms that are more prevalent in younger adults, such as sleep paralysis and hypnogogic/hypnopompic hallucinations, have not been studied. In particular, their role in mental health, independent of insufficient sleep duration or insomnia, has not been evaluated in this group. Data were collected...

Quantitative Determination of LSD and a Major Metabolite, 2-Oxo-3-Hydroxy-LSD, in Human Urine by Solid-Phase Extraction and Gas Chromatography-Tandem Mass Spectrometry

Journal of Analytical Toxicology September 1, 1999 Scott Reuschel, Shaundel Percey, S. Liu et al. 38 citations

An assay has been developed for quantitative determination of lysergic acid diethylamide (LSD) and a major metabolite of LSD in human urine at concentrations as low as 10 pg/mL. In most LSD-positive urine samples the metabolite, 2-oxo-3-hydroxy-LSD, is present at higher concentrations than LSD and can be detected for a longer time than LSD after ingestion of the drug. Urine samples are...
