    Notes: [Auszug] THE reform of Sweden's Research Councils due to go into effect on July 1 this year is basically an attempt to set up a structure which will accommodate both society's need for research that produces usable and useful results, and the scientists' traditional demand for freedom in conducting ...

    Notes: [Auszug] When TMV reassembles, the uncoated RNA is folded back along the growing rod, probably down the central hole. This surprising configuration is essential for rapid elongation—presumably supplying RNA to its site of incorporation while keeping the bulk of the free RNA out of the ...

    Notes: [Auszug] In this SSC model the non-thermal radio, X-ray, and optical emission originate in an extremely small region located in the nucleus of the galaxy. The non-thermal flux causes photoionisation of the gas in this nucleus which results in the observed strong emission-line optical spectrum. In addition ...

    Notes: [Auszug] ATP depletion of red cells was accomplished by incubating washed red cells at 37 °C in either a glucose-free Tris-buffered saline medium or in the same medium containing 1 mM iodoacetate and 0.2% glucose. In both the systems the ATP content of the red cells at various periods of incubation was ...

    Notes: [Auszug] To determine whether the responsiveness of Leydig cells of Tfm rats to hCG differed from that of normal males, we incubated Tfm and normal testes with the same dose of hCG. Figure 1 shows the response in terms of testosterone released into the medium. The Tfm testes exhibited a markedly impaired ...

    Notes: [Auszug] The mean membrane current changes in time in response to a pulse of constant voltage (voltage clamp). It rises to a maximum within 25 ms and stays there for pulses shorter than 200 ms (refs 10, 11). Inactivation, that is, a subsequent decrease of the potassium current, occurs with longer pulses. ...
