    Fine Structure of Hepatozoon mocassini (Apicomplexa, Eucoccidiorida) Gamonts and Modifications of the Infected Erythrocyte Plasmalemma (1985)

    Notizen: Transmission electron microscopy and scanning electron microscopy were used to investigate the fine structure of Hepatozoon mocassini gamonts and modifications of the infected erythrocyte plasmalemma. Intraerythrocytic gamonts were contained within a parasitophorous vacuole. An electron-lucid space observed between the gamont pellicle and the membrane of the vacuole corresponded to the unstained space described in light microscopy studies. Gamonts possessed a conoid, polar ring, subpellicular microtubules, four pairs of rhoptries, micronemes, ovoid granules, mitochondria with tubular cristae, and a pellicle composed of three individual unit membranes. The conoid had an anterior diameter of 320 nm, a posterior diameter of 360 nm, and a length of 150 nm. In contrast to a report on Hepatozoon aegypti, no micropore or “canopy-like structure” was observed. The plasmalemma of infected erythrocytes exhibited two types of modifications: gross membrane deformations and knobs with an electron-dense central mass. These knobs are structurally distinct from previously described membrane excrescences.

    An in Vitro Assay for Sequestration: Binding of Plasmodium falciparum-Infected Erythrocytes to Formalin-Fixed Endothelial Cells and Amelanotic Melanoma Cells (1985)

    Notizen: Erythrocytes infected with Plasmodium falciparum bind specifically to cultured endothelial cells and to a line of amelanotic melanoma cells. We have fixed endothelial cells and amelanotic melanoma cells in various ways and determined whether the fixed cells were still able to bind infected erythrocytes. Only cells fixed with 1.0-2.5% formalin in phosphate-buffered saline continued to bind infected erythrocytes as well as unfixed cells. The mechanism of binding to fixed and unfixed cells appeared to be identical for the following reasons. First, erythrocytes infected by parasite strains that bound to unfixed cells also bound to fixed cells while those that did not bind to unfixed cells did not bind to fixed cells. Second, immune serum that inhibited binding to unfixed cells also inhibited binding to fixed cells. Third, electron microscopy showed that knobs were the points of attachment between infected erythrocytes and both fixed and unfixed melanoma cells. Fixed cells gave reproducible results over at least 2 months. Thus, we have developed a simplified, reproducible assay for measuring binding of P. falciparum-infected erythrocytes to target cells.

    Structural Alteration of the Membrane of Erythrocytes Infected with Plasmodium falciparum (1985)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 32 (1985), S. 0

    Thema: Biologie
    Notizen: Human erythrocytes infected with five strains of Plasmodium falciparum and Aotus erythrocytes infected with three strains of P. falciparum were studied by thin-section and freeze-fracture electron microscopy. All strains of P. falciparum we studied induced electron-dense conical knobs, measuring 30–40 nm in height and 90–100 nm in diameter on erythrocyte membranes. Freeze-fracture demonstrated that the knobs were distributed over the membrane of both human and Aotus erythrocytes. A distinct difference was seen between the intramembrane particle (IMP) distribution over the knobs of human and Aotus erythrocyte membranes. There was no change in IMP distribution in infected human erythrocyte membranes, but infected Aotus erythrocytes showed an aggregation of IMP over the P face of the knobs with a clear zone at the base. This difference in IMP distribution was related only to the host species and not to parasite strains. Biochemical analysis demonstrated that a higher proportion of band 3 was bound to the cytoskeleton of uninfected Aotus erythrocytes than uninfected human erythrocytes after Triton X-100 extraction. This may account for the different effects of P. falciparum infection on IMP distribution in the two different cell types.

    TWO-PASS 3D MIGRATION AND LINEARIZED INVERSION IN THE (x, t)-DOMAIN (1989)

    Notizen: 3D Kirchhoff migration and acoustic Born inversion of zero-offset seismic data in a constant-velocity medium can be uniformly factored as a cascade of two 2D diffraction integrals. The formal argument is based on a straightforward implementation of the original time-domain approach of Gibson, Larner and Levin. The factorization differs from the factorization described by Jakubowicz and Levin in omitting all time-dependent filters from the 2D operators in favour of ID filtrations performed as a preprocess and a postprocess.

    Trends and developments in industrial relations and industrial relations law: Trade union discipline and non-strikers (1989)

    Notizen: Perhaps the most controversial change introduced in the 1988 Employment Act was the statutory right given to union members not to be disciplined by their unions for continuing to work during lawful industrial action approved by a majority in a secret ballot. Here the authors examine the legal contexts, implications for trade unions and the wider industrial relations and political significance of this important new right.

    Notizen: Although the US labor movement remains an important part of the nation's organized economic and political life it is now struggling to reverse its decline in power and membership. In this article the author identifies factors explaining this decline and its implications for American labor. This contribution continues the debate begun by Michael Piore in Vol 17 No 3 Autumn 1986.

    A Synthesis of Some Market Area Delimitation Models (1989)

    Notizen: Reilly's law of markets delimits a breakpoint between the trade areas of a pair of centers based on their size and spatial separation. The construction of trade boundaries between more than two centers is inadequately dealt with in the literature. This paper generalizes Reilly's market model using probability contour mapping and numerical integration. Since the allocation phase of the model can be based on any suitable interaction model, a wide variety of retail analysis techniques is synthesized. Using computer graphics, both descriptive and predictive uses of the model are illustrated.

    Notizen: If markets are to be subsumed within socialism, the institutions of ownership upon which they are based will require adaptation. David Miller, Official Fellow at Nuffield College, Oxford, suggests that the dangers to market freedom posed by the private ownership of capital may be eliminated by cooperatives and other new forms of ownership.
