The diagnosis of cardiac allograft rejection is currently based on endomyocardial biopsy and histologic evaluation. Since the introduction of cyclosporine, cardiac biopsy has been recognized as the only reliable method of diagnosis. From July 1985 to June 1986, 22 transplant

Cyanelle peptidoglycan from the glaucocystophyte algae Glaucocystis nostochinearum and Cyanoptyche gloeocystis was investigated by high-performance liquid chromatography of muropeptides, supported by matrix-assisted laser desorption-ionization mass spectrometry. The peptidoglycans of both species are modified with N-acetylputrescine, as has been demonstrated for
Increase in urinary polyamine levels after transplantation was suggested to be an indicator of organ rejection but immunosuppression therapy could also give rise to these polyamines. To test this hypothesis, the urinary excretion of N-acetylputrescine (Nap) and N-acetylspermidine (Nas) was

The photosynthetic organelles (cyanelles) of the protist Cyanophora paradoxa are surrounded by a peptidoglycan wall, modified through amidation with N-acetylputrescine. Cyanelle envelope membrane preparations were shown to catalyze the lipid-linked steps of peptidoglycan biosynthesis as well as the putrescinylation and
An improved gas chromatographic method for the determination of urinary acetylpolyamines.
