    Notes: Summary The effects of a bone resorptive protein isolated from human cancer ascites fluid on bone cell calcium and cyclic AMP were studied with fetal rat cells. The osteoclast-activating factor increased bone cell calcium uptake at 37°C and 4°C with no direct effects on calcium efflux. Concentrations of the resorptive factor that increased in vitro bone resorption and cell calcium uptake had no effect on cyclic AMP. The effects of the protein on calcium uptake were not specific for bone cells, and large increases were also observed in isolated fetal rat skin cells. These studies suggest that increases in the permeability of the cell membrane to calcium are involved in the mechanism of action of the ascites fluid resorptive protein.

    Notes: Abstract Competition of strong and decoupling is studied systematically for odd-odd mass nuclei as a function of the position of the Fermi surfacesε F (π) andε F (υ) and the deformationsβ andγ. As an example we use80Br. For a prolate deformation the odd proton likes to decouple while the odd neutron couples strongly. This favours a ground state angular momentum of 5 to 6. The strong coupling is described by the admixture of ad 5/2 nucleon. Only for the neutrons the admixture is so appreciably that it affects the spectrum and improves the agreement between theory and experiment for80Br.

    Notes: Abstract An attempt is made to take into account single particle degrees of freedom in angular momentum projected HFB-calculations via the explicit inclusion of two quasiparticle states. For this purpose a formalism is used which, though being rather general, nevertheless is rather suitable for numerical applications even in realistic model spaces. As a first test the method is applied in thei 13/2-shell, where exact shell model solutions are available. Though using only a rather truncated quasiparticle space we obtain almost perfect agreement with these exact solutions.

    Description / Table of Contents: Zusammenfassung Ein aufPlanorbis planorbis gefundener Oligochaet wurde alsChaetogaster limnaei K.E. v. Baer identifiziert. Es erwies sich, daß Schnecke und Oligochaet in einer gewissen Symbiose leben. Bei Infektionsversuchen verschlangChaetogaster Pansenegelmirazidien und schützte damit den Wirt wirkungsvoll vor einer massiven Invasion, weiterhin fraß er schwärmende Zerkarien und beeinträchtigte so den Lebenszyklus des Trematoden.Chaetogaster limnaei läßt sich von Versuchschnecken entfernen, wenn diese 8 h lang bei +32° C–34° C Wassertemperatur gehalten werden.
    Notes: Summary An oligochaet found onPlanorbis planorbis was identified asChaetogaster limnaei K.E. v. Baer. Snail and oligochaet apparently lived in a relationship of symbiosis.Chaetogaster ingested miracidia of the stomach flukeParamphistomum cervi, thus protecting the host effectively from massive invasion; further moreChaetogaster influenced the life cycle of the trematode by ingesting swarming cercariae.Chaetogaster limnaei can easily be removed by keeping the snails for 8 h at +32–34° C water temperature.
