    Notes: [Auszug] We present here electron microscopic evidence, from posterior pituitary glands of rats and hamsters, leading to a quite different view, namely that the neurosecretory granules void their contents directly to the cell exterior by the process of exocytosis, and that synaptic vesicles arise as ...

    Description / Table of Contents: Summary Upon addition of Congo red, neutral aqueous solutions of amylose show several induced Cotton-effects in the regio of the dye absorption bands. It is assumed that Congo red forms sterically ordered adducts with helical amylose segments. With several other azo dyes (methyl orange, α-naphthol orange, chrysophenin G), no induced Cotton-effects were observed.
    Notes: Zusammenfassung In neutralen wäßrigen Lösungen, die Amylose und Kongorot enthalten, treten im Bereich der Absorptionsmaxima Abweichungen von der normalen optischen Rotationsdispersion und mehrere induzierte Cotton-Effekte auf. Hieraus wird auf eine geordnete Assoziation der Farbstoffmoleküle an helicale Segmente der Amylose geschlossen. Bei Methylorange, β-Naphtholorange und Chrysophenin G sind keine induzierten Cotton-Effekte zu beobachten.
