    Selective effects of gonadal steroids on the response of peripheral serotonin receptors (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 407-408 
    Details
    ISSN: 1420-9071
    Keywords: Rat, stomach strips, isolated ; serotonin receptors, peripheral ; androgen-sensitive contraction ; estrogen-refractory contraction
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The maximal contraction provoked by serotonin (5-HT) in isolated stomach strips of adult rats, a functional index for peripheral 5-HT receptors, was sexually differentiated, androgen-sensitive, and estrogen refractory. This is at variance with the reported sensitivity of central 5-HT receptors to estrogen.

    Structure and reactivity of Zn-Cr mixed oxides. Role of non-stoichiometry in the catalytic synthesis of methanol (1989)
    Springer
    Catalysis letters 3 (1989), S. 65-72 
    Details
    ISSN: 1572-879X
    Keywords: Methanol synthesis ; zinc-chromium mixed oxides
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The catalytic behaviour of Zn/Cr mixed oxides with different compositions was investigated as a function of the bulk and surface properties. It was observed that non-stoichiometric spinel-type phases were stable also in the reaction conditions, in which zinc-surface enrichment did not occur. The maximum productivity in methanol was observed for monophasic non-stoichiometric spinel-type samples with a Zn/Cr ratio near to one, whereas the samples richest in zinc, for which a side phase, ZnO also was detected, showed a strong decrease in activity. The catalytic data support the hypothesis that non-stoichiometric spinel is the active phase for the synthesis of methanol on coprecipitated Zn-Cr catalysts.
