Wood Development

During the years 1974-1975 on rotting cherry wood development of some Myxomycetes was observed. In that time 6 species of slime molds were noted: <i>Arcyria denudata, Comatricha typhoides, Dyctidium cancellatum, Lycogala epidendrum, Physarum cinereum, Stemonitis ferruginea</i>. In the decomposition of organic compounds apart from <i>Myxomycetes</i> other organism (<i>Coprinus dessiminafus</i>) also take part.

The Origin Of Life

AbstractDifferent current ideas on the origin of life are critically examined. Comparison of the now fashionable FeS/H2S pyrite-based autotrophic theory of the origin of life with the heterotrophic viewpoint suggest that the later is still the most fertile explanation for the emergence of life. However, the theory of chemical evolution and heterotrophic origins of life requires major updating, which should include the abandonment of the idea that the appearance of life was a slow process involving billions of years. Stability of organic compounds and the genetics of bacteria suggest that the origin and early diversification of life took place in a time period of the order of 10 million years. Current evidence suggest that the abiotic synthesis of organic compounds may be a widespread phenomenon in the Galaxy and may have a deterministic nature. However, the history of the biosphere does not exhibits any obvious trend towards greater complexity or «higher» forms of life. Therefore, the role of contingency in biological evolution should not be understimated in the discussions of the possibilities of life in the Universe.

Inactivation of Antiplasmin and Complement C1 in Human Plasma Rendered Fibrinolytic by Synthetic Organic Compounds

SummaryCertain synthetic organic compounds induce upon dissolution marked fibrinolytic activity in human plasma, reduce the antiplasmin titer of human or bovine serum and destroy the complement C1 of human plasma. Generation of fibrinolytic activity and reduction of antiplasmin are concentration-depending time reactions. Destruction of complement C1 occurs almost instantaneously. Minor molecular modifications abolish all three activities of the compounds.
