    [s.l.] : Nature Publishing Group
    Nature 273 (1978), S. 62-64 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Preparations of a suitable size for mechanical experiments were usually obtained by placing a strip of muscle in a relaxing solution (Table 1) a^room temperature (20-25 C) and subdividing the strip into fibre bundles about 50-200 ^m thick and 50-500 /im wide. In some experiments individual fibre ...

    Hexuronic Acid as the Antiscorbutic Factor ( Reprinted from Nature, April 16, 1932) (1969)

    Notes: [Auszug] EXPERIMENTS are being carried out in order to decide whether ' hexuronic acid ' is the antiscorbutic factor. So far as is known, the distribution of this acid in plants follows closely the distribution of vitamin C. In the animal body it can also be found in relatively high concentration in the ...

    Control of tension development in scallop muscle fibres with foreign regulatory light chains (1980)
    [s.l.] : Nature Publishing Group

    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The tension response of a chemically skinned fibre bundle to an activation-relaxation sequence is shown in Fig. la. There was no tension development in relaxing solution ([Ca2+]〈 1010 M) and maximal development in activating solution ([Ca2+] = 1(T48M). Treatment with EDTA at 25 C removed both ...

    ‘Window Fields’ in Muscle (1951)
    [s.l.] : Nature Publishing Group
    Nature 167 (1951), S. 482-482 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] It is an interesting property of the 'window field' that its time integral is independent of the sharpness of the borderline of the wave of depolarization, and that the time integral of the component of the field parallel to the axis is identical for any point of the cross-section. It is equally ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] WE have been led to regard ‘myosin’ as a rather involved system of substances, in spite of the fact that it readily crystallizes and behaves as a homogeneous substance on recrystallization. It consists of a skeleton to which are adsorbed a number of protein like substances. The skeleton, and ...

    Notes: [Auszug] THE chemical nature of the tigroid (Nissl's granules) of nervous cells is still unknown. On morphological grounds they are generally supposed to be related to the nucleus. The brains of freshly killed guinea-pigs were fixed in alcohol, embedded in paraffin, and dissected. If stained with ...

    Notes: [Auszug] IN a previous paper (Biochem. Z., 181, 433; 1927) it was shown that extracts of the adrenal cortex strongly reduce silver nitrate and iodine. This reduction could not be accounted for either by adrenalin or glutathione, and seemed to be specific to the interrenal tissue. To exclude any ...

    Notes: [Auszug] WE reported in our previous notes1 on the vitamin nature of phenyl-benzo-γ-pyrone dyes, and have described a method for the experimental demonstration of this activity. Using this method, we tested the following substances for their vitamin activity: hesperidine (m.p. 261°), an ...

    Notes: [Auszug] THE respiration of the minced breast muscle of the pigeon has been studied by means of specific poisons (malonic, maleic and arsenious acid). Experiments show that in the main process of respiration, no substances other than succinic acid and its first oxidation product, fumaric acid and the ...

    Notes: [Auszug] THE hind limbs of a Hungarian frog are perfused with veratrine 1/50,000 in Ringer's solution. The liquid collected from the vein perfuses a second, similar Trendelenburg's preparation. Direct tetanic stimulation of the hind limbs of the first frog is followed, after a latent period of about 10 ...
