    Notizen: Abstract Body weight distributions of the amphipod Paramoera walkeri colonizing litter-bags at different depths (2, 5, and 10 m) in Terra Nova Bay were compared. This species dominated the vagile benthic community and was found nearly alone at the shallow sites. At the deepest site it co-occurred with two smaller benthic species (the gastropod Laevilitorina antarctica and the isopod Munna antarctica) but still accounted for most of the animal biomass (80.2%). The frequency size-class distributions of the three dominant species were sharply distinct in a condition of stable coexistence. The total biomass was inversely related to the abundance of animals and diminished with increasing depth. Both species and size-class diversities were higher in deep water which offered a more diversified and favourable habitat than shallow water. At the shallow sites only the large size classes of P. walkeri were present. Differences in the mean individual ash content between samples support the hypothesis that different size individuals of P. walkeri segregated along the depth gradient on the basis of their metabolic requirements and the related ability to exploit sub-optimal environments.

    Notizen: We have studied the photophysics of linear trans-quinacridone films by applying a variety of transient and continuous wave photomodulation techniques. Our experimental results demonstrate the ultrafast formation of excimer species which are responsible for the emission. The excimer decay kinetics seems to suggest a predominantly charge transfer character of these emitting species. This is consistent with the long-lived states which we detected on the millisecond time scale. © 1997 John Wiley & Sons, Ltd.

    Notizen: Hexokinase inactivating antibodies were loaded into human erythrocytes using an encapsulation procedure based on hypotonic haemolysis, isotonic resealing and reannealing. Red blood cells loaded with anti-hexokinase IgG showed 20 percent residual hexokinase activity and reduced glycolytic activity. 9Incubation of these cells in the presence of an oxidizing agent such as terbutyl hydroperoxide (TBH) and then in autologous plasma, promoted opsonization by autologous IgG and complement deposition, but not haemolysis. Furthermore, the antihexokinase IgG loaded cells treated with TBH were actively recognized and phagocytosed by macrophages. Thus, metabolic impairment of human erthrocytes promotes autologous IgG binding, C3 deposition and phagocytosis, a mechanism already reported for the removal of senescent erythrocytes.
