    Notes: [Auszug] While it is clear that not all hydrolytic enzymes are lysosomal6-8 there is compelling evidence9 that lysosomal hydrolases are the main agents in the catabolism of regressing tissues. Moreover, many of the enzymes considered to be lysosome-linked exhibit marked activity in the transitional ...

    Notes: [Auszug] ONE type of photosensitization results from the accumulation in the blood and tissues of substances normally eliminated in the bile; it is the accumulation of such substances which provokes the characteristic reaction of the skin to light. In several such instances with livestock the major factor ...

    Cosmic gamma rays and molecular gas in the galaxy (1983)
    Springer
    Space science reviews 36 (1983), S. 155-159 
    Details
    ISSN: 1572-9672
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A brief analysis is made of the interrelation of the intensity of cosmic-ray particles, the column density of gas and the intensity of cosmic γ-rays. It is shown that, locally, γ-ray data enable the calibration of H2 densities to be inferred from CO data and elsewhere the variation of cosmic-ray intensity with position to be assessed. Finally, the importance of cosmic-ray irradiated molecular clouds in simulating γ-ray ‘sources’ is reiterated.

    The effect of agents influencing cytoskeletal elements upon the dielectrophoretic behavior of cultured epidermal cells (1981)
    Springer
    Journal of biological physics 9 (1981), S. 87-96 
    Details
    ISSN: 1573-0689
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Physics
    Notes: Abstract The degree of alignment of epidermal cells when subjected to an ac electrical field of different frequencies was studied. In untreated cells the alignment increased with field frequency between 20 and 600 kHz. Microtubular inhibitors, colchicine and vinblastine sulfate, decreased the response at 600 kHz and increased the response at 200 kHz. Dimethyl sulfoxide decreased the alignment at all frequencies studied and a microfilament inhibitor, cytochalasin B, was found to abolish this decrease. Possible reasons for these observations are given and the relevance to cell-cell communication discussed.
