    Regenerated Keratin Fibres (1949)
    [s.l.] : Nature Publishing Group
    Nature 163 (1949), S. 18-19 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE elastic properties of the keratin fibres, wool and hair, have been shown to result from a folded molecular structure capable of reversible extensibility1. This folded structure gives rise to a large-angle X-ray pattern, referred to as the α-pattern, which characterizes an ...

    Notes: [Auszug] In order to make sure of the exact disposition of this residue within the cortex, the experiment has been carried out on cross-sections of oxidized hair. On treatment with ammonia, these cross-sections swelled to about three times their original diameter and the cortical residue was seen to extend ...

    Notes: [Auszug] THE friction apparatus devised by Bowden and Leben1 to examine the friction of metals has been used to study the frictional properties of wool fibres. Some accessories were made to adapt the apparatus to the application of loads of 0.05–1 gm. and the measurement of small ...

    Notes: [Auszug] The existence of a subcuticular membrane in animal hairs was suggested by the German workers Lehmann5'6 and ElcSd and Zahn7 several years ago. Their evidence for a subcuticular origin for the tubular residues has already been criticized and the tubes shown to be derived from the external layers of ...

    Notes: [Auszug] THE generally accepted model of the structure of keratin proposed by Astbury and Bell1 is based first on the crystallographic data obtained from X-ray studies on whole wool fibre, and secondly upon the interpretation of experiments on whole fibre extension in water, that is, 100 ...

    Notes: [Auszug] THE rootward migration of individual wool fibres is generally accepted as the cause of the felting of wool. Such a migration is made possible by the existence of a difference between the coefficient of friction for motion in the rootward and that in the tipward direction along the fibre. ...

    Notes: [Auszug] IN the recent literature concerning the process of keratin formation, as revealed by electron microscopy, different terms have been used to describe the special intracellular products appearing during keratinization. As a result, communication between investigators has been hindered, and apparent ...

    Notes: [Auszug] Fixation of bacteria with the buffered osmium tetroxide solution, commonly employed for animal tissues, has for some time been regarded as unsatisfactory for electron microscopy2. In particular the nuclear cavity and contents are poorly preserved. On the other hand, fixation in a buffered solution ...

Electron micrograph of a cross-section of a crumpled monolayer of egg albumen stained with osmium tetroxide The cross-section of the crumpled sheet of protein appeared as a thin, dense, highly convoluted line (Fig. 1). Since the thickness of the best sections (about 200 A-) was still some ...

    Notes: [Auszug] In normal growth a steady stream of cells, maintained by division in the neighbourhood of the papilla at the base of the follicle, passes up the tube formed by the outer root sheath and differentiates to form as many as six concentric cylinders ; the three outer cylinders constitute the inner root ...
