These proceedings fonn the outcome of an International Conference on "Impacts of Global change on Tree Physiology and Forest Ecosystems," held from 26-29 November 1996, at Wageningen, The Netherlands. The conference brought together biologists, ecologists, and forest scientist working in the field of impacts of elevated CO and air pollution on tree physiology and forest ecosystems, and marked the 2 completion of a European COST action on "Impacts of Elevated C02 levels and Air Pollutants on Tree Physiology" (ICAT / COST-614), as well as the conclusion of the frrst phase of an EU-funded...

Sowohl die contractilen Eiweisse, wie die Mechanik und die Elektro physiologie sind beim glatten Muskel weniger intensiv bearbeitet worden als beim Skeletmuskel. Deshalb sind gewisse Gebiete der Glattmuskelphysiologie...

53 catalytic interaction between enzyme-coenzyme complex and substrate (VENNESLAND and WESTHEIMER 1954; VENNESLAND 1955,1956; GUTFREUND 1959) have all been the subject of numerous excellent and exhaustive reviews. These topics, therefore, will not be treated in extenso here. The present summary will deal instead with more recent observations on the pyridine nucleotide dependent dehydrogenases which have necessitated a re-examination of their function and structure in the light of new information concerning their composition. The new compositional characterization of these enzymes dates from...
