    Culture of Algae and other Micro-organisms in Deuterium oxide (1959)
    [s.l.] : Nature Publishing Group
    Nature 184 (1959), S. 729-730 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Algae require a prolonged period for adaptation or acclimatization to deuterium oxide. We have observed that an adaptation time of at least 200 hours is usually necessary before appreciable growth occurs. Such protracted adaptation periods appear to be far longer than those previously employed, and ...

    Importance of the Synthesis of Acidic Polysaccharide for Wound Healing (1958)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] We have presented experimental evidence in support of our suggestion2-4 that the healing of open wounds is dependent upon the ability of the tissues to synthesize, at the site of injury, certain sulphated mucopolysaccharides. Administration of cortisone elicits a reduction in the synthesis of acid ...

    Net Synthesis of Lecithin in an Isolated Enzyme System (1956)
    [s.l.] : Nature Publishing Group
    Nature 178 (1956), S. 594-595 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Previous experiments on the biosynthesis of lecithin in isolated enzyme systems have required the use of isotopic tracers, since the amounts of newly formed phospholipid were too small to be detected by conventional chemical methods. In such experiments, it was impossible to rule out the occurrence ...

    Notes: [Auszug] Michaelsen's specimens were from the Caucasus, and up to 19471 the only British records were two specimens from Limerick2 and one specimen (?) from Colwyn Bay, North Wales8. In 1954, two specimens were sent to the British Museum (Natural History) from a compost heap in Staffordshire. Var. zebra ...

    The potential of somatic hybridization in crop breeding (1955)
    Springer

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary In recent years, the rapid development of somatic cell genetics has made possible the transfer of alien genes over wide taxonomic distances by somatic hybridization. In this review, the potential of somatic hybridization in the breeding of crops within the Brassicaceae, Fabaceae, Poaceae and Solanaceae is discussed. It is evident from these studies that many hybrids, either symmetric or asymmetric, which are fertile have the potential to be used as a bridge between the alien species and the crop. Progeny analysis of some hybrid combinations also reveals intergenomic translocations which may lead to the introgression of the alien genes. Furthermore, fusion techniques enable the resynthesis of allopolyploid crops to increase their genetic variability and to restore ploidy level and heterozygosity after breeding at reduced ploidy level in polyploid crops.
