    Cerebral neuroblastoma (1978)

    Notes: Summary A cerebral neuroblastoma removed surgically from a female child is presented. Electron microscopy showed numerous neuronal processes with growth cones which are a feature of the developing neurone. In addition there were some rosettes with distinct lumina. The luminal surfaces were covered with a smooth plasma membrane lacking any surface differentiation and the lateral surface of these cells had many cell junctions (terminal bars), reminiscent of a primitive neural tube. These features in a nerve cell tumor help to substantiate it as a neuroblastoma arising from immature rather than differentiated cells. The nature of this rare tumor is discussed.

    Comparative platelet anti-aggregant activity of D-cysteinolic acid analogues (1989)
    Springer
    Cellular and molecular life sciences 45 (1989), S. 1110-1112 
    Details
    ISSN: 1420-9071
    Keywords: D-Cysteinolic acid ; platelet aggregation ; inhibitor ; marine product ; 2-aminoethyl disulfide ; sardine

    Topics: Biology , Medicine
    Notes: Summary D-Cysteinolic acid (1) analogues with an S-C-C-N skeleton showed increased platelet anti-aggregant activity in the following order: 2-aminoethanesulfonic acids, thiazolidines, 2-aminoethanethiols and 2-aminoethyl disulfides. Methyl substitutions at the 2-position potentiated the activity. Of these analogues, bis [(R)-2-aminopropyl] disulfide was the most potent inhibitor of platelet aggregation, with about 600-fold the activity of (1).
