Isocoproporphyrin: nuclear-magnetic-resonance-and mass-spectral methods for the determination of porphyrin structure.
The use of ;shift reagents' in the determination of n.m.r. spectra, and of reductive alkylation in combination with g.l.c.-mass spectrometry, facilitates assignment of the order of substituents in porphyrins, and the application of these new techniques to isocoproporphyrin is described.

Urinary modified nucleosides as tumor markers.
Extracts of urinary nucleosides have been sequentially purified and examined by mass spectrometric analysis. Seventeen modified nucleosides have been unequivocally identified and a further five provisionally identified. While several nucleosides were found only in a small number of extracts, the occurrence and levels of others were found to correlate with the tumour type and stage.
