    Notes: [Auszug] In the following I give a model which with a simple and natural constraint has the ability to detect linear relations and record their components in a principal axis frame of reference; as such it has obvious relations with well-known topics of linear analyses, namely, multiple factor5, and ...

    Notes: [Auszug] One of us (M. C. G.)2, using the glycerated fibre preparation1 of rabbit psoas muscle, has confirmed this by showing that ionic media which produce dissociation of actomyosin3 cause a reduction in elastic modulus of the fibres under isometric conditions, although in all these cases the conditions ...

    Notes: [Auszug] Previously5 a physical argument was given for the exceptional Lie group F as candidate for the above. This turned on the interpretation of the wave equation as not being (Hermitian) self -adjoint, thus implying the existence of a non-unitary representation. An attempt6 was made to give a path ...

    Reconstitution of a proton pump from gastric mucosa (1977)
    Springer
    The journal of membrane biology 35 (1977), S. 285-301 
    Details
    ISSN: 1432-1424
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Summary Purified vesicular fractions from hog gastric mucosa have been incorporated into phosphatidyl serine bilayers. In the presence of MgATP on one side and symmetrical Na2SO4 solutions, a short circuit current (SCC) away from that side is observed increasing exponentially with time, while the corresponding open circuit potential (OCP) is maintained constant for 〉30 min. In K2SO4 solutions the SCC time course is essentially unchanged, but the OCP falls to almost zero after 15–20 min. In Na−K gradient there is a similar SCC away from the K-side whose exponential rate is increased by ATP added to both sides. The time course of these events depends only on the time from the formation of the black film. These results are interpreted as showing: (1) There is an ATP-driven proton pump generating a constant potentialE H in series with a time dependent conductanceg H ∝ e kt . (2) There is a shunting K-conductanceg K ∝ e k't . (3) In the presence of ATPk'〉k. (4) This time dependence is due to thickness changes in the bilayer. A model relates these results to those obtained with the intact vesicles.

    Notes: [Auszug] SIR - The book review by Frank Barnaby (Nature 16 June, p.639) is ominous. When he says the nuclear arms race may be out of political control, what he means, and later implies, is that in a formally democratic society it is out of democratic control because it is in the hands of special interests. ...

    Reversal of Relaxing Mechanism in Muscle Fibre Systems by Hydrostatic Pressure (1956)

    Notes: [Auszug] The discovery of an in vitro contraction cycle by Goodall and A. G. Szent Gy rgyi4 provides a model of activation which works simply through small changes of pH. It is of interest, therefore, to see how far this system resembles intact muscle in its reaction to pressure. First the dependence of ...

    Notes: [Auszug] In another direction it has been shown by a number of workers3-5 now that transphosphorylation to adenosine diphosphate is an essential, though not in itself sufficient6, part of the relaxation mechanism in muscle. Furthermore, the possibility of an unidentified phosphate donor has been noted7 in ...

    Notes: [Auszug] We wish to report discrete changes of conductance after the incorporation of an ACh receptor preparation into artificial lipids bilayers. These events were related to a unit conductance that is probably associated with some fundamental function of the receptor. Receptors were extracted by ...
