The antitumor agent taxol has been examined by electron ionization, chemical ionization, and fast atom bombardment mass spectrometry. Three ion series are observed: (1) the M-series, characteristic of the intact molecule; (2) the T-series, with fragments derived from the taxane ring; and (3) the S-series representing the C-13 side chain. Neutral losses(More)
The notion of individual transferable quotas (ITQs) has permeated the fisheries economics literature over the last 40 years. The most long-standing prediction about ITQs has been extensively documented, namely that transferable property rights to harvest induce changes along the extensive margin via consolidation of quota among a smaller number of vessels.(More)
Modified nucleosides from pooled normal human urine were extracted using a boronate affinity gel column and fractionated by reversed-phase high-performance liquid chromatography (RP-HPLC). The major constituents in each of the 30 RP-HPLC fractions were determined by gas chromatography-mass spectrometry of the trimethylsilyl derivatives of the fractions. The(More)
A comparative mass spectral examination of the trimethylsilyl (TMS) derivatives of 2'-, 3'- and 5'-deoxyadenosine, 2'-, 3'- and 5'-deoxyguanosine, 2'-, 3'- and 5'-deoxyxanothosine and 2'- and 5'-deoxy-2-fluoroadenosine is presented. A general compilation of the major fragment ions found in the low-resolution electron ionization (EI) spectra of the eleven(More)
The identification of 5,6-dihydrouridine in normal human urine is reported. Partial purification and isolation of the compound by boronate gel affinity chromatography and reversed-phase high-performance liquid chromatography preceded its characterization as a trimethylsilyl derivative by combined gas chromatography/mass spectrometry. Structure proof is(More)
When I (Weber) was three, my father had a total laryngectomy. His stoma did not bother me, and it was common to see him cough through his neck, though I never became used to the excessive secretions produced. My father mastered esophageal speech well, so communication was normal. No one in my family can remember what his voice was like before the operation.(More)
