MRI and contrast-enhanced CT scan revealed symmetric bilateral frontal cysts (figure 1A) and an anterior skull base nodule (figure 1, B and C). Surgery confir...

In this paper the taxonomy of some previously reported taxa as Cercospora apii s.lat. in Iran, is discussed and some new records are listed.

A precursor application system was developed to allow the study of Erythrina alkaloid formation in Erythrina crista-galli. Fruit wall tissue of this species was recognized as the major site of alkaloid biosynthesis. The application of radioactively and 13C-labelled potential precursors showed that the hitherto assumed precursor (S)-norprotosinomenine was not incorporated into the Erythrina alka...
