Urinary bile acids from a 3-mo-old boy with cholestatic jaundice were analyzed by ion exchange chromatography and gas chromatography-mass spectrometry (GC-MS). This suggested the presence of labile sulfated cholenoic acids with an allylic hydroxyl group, a conclusion supported by analysis

A high-performance liquid chromatographic method for the determination of the anti-arrhythmic drug mexiletine in human plasma, urine, and cerebrospinal fluid is described. Following extraction with diethyl ether, mexiletine and the internal standard 4-methylmexiletine were derivatized with 2,4-dinitrofluorobenzene. Analyses were performed

Experimental and mathematical modeling studies were performed to examine the effects of stabilizing agents on the transport and retention of fullerene nanoparticles (nC(60)) in water-saturated quartz sand. Three stabilizing systems were considered: naturally occurring compounds known to stabilize nanoparticles (Suwannee
