T was about the Beginning of September 1664, that I, among the Rest of my Neighbours, heard in ordinary Discourse, that the Plague was return'd again in Holland; for it had been very violent there, and particularly at Amsterdam and Roterdam, in the Year 1663, whether they say, it was brought, some said from Italy, others from the Levant among some Goods,(More)
A new structural transition in nerve myelin has been discovered by means of X-ray diffraction of excised teleost nerves in physiological saline. The reversible transition is between two structures, designated AS and AL, with repeating distances (d spacings) differing by 25-35 A. When the temperature of bream spinal cord is lowered from room temperature to 4(More)
Scanning along human acoustovestibular nerves from cross-sections closely proximal to the brain to locations distinctly peripheral thereto, by means of small-angle X-ray diffraction, has disclosed transitional junctions at which the myelin structure typical of central nervous system (CNS) axons gives way to one characteristic of peripheral (PNS) fibers. The(More)
Earlier small-angle X-ray diffraction studies have indicated that central and peripheral nerve myelins may be significantly different structurally, although relatively few examples for each system and for individual species have been examined. In order to understand better the intra- and inter-system relationships, this study has developed more extensive(More)
