    Bacteriocins from Myxococcus fulvus (Myxobacterales) (1977)

    Notes: Abstract Bacteriocin-like activities were found in several Myxococcus fulvus strains. One strain, Mxf16, exerted strong inhibitory effects on several myxobacterial strains. Synthesis of its bacteriocinic activity could not be induced by mitomycin. Electrophoresis and molecular sieve chromatography revealed at least three different bacteriocinic substances of low molecular weight.

    Notes: Abstract Fulvocin C is a bacteriocin from Myxococcus fulvus Mx f16. It has a molecular weight of 4672 and is one of the smallest bacteriocins known. Four disulfide bonds give the molecule a tight structure, so that its native form was not attacked by chymotrypsin or pronase. Fulvocin C was stable in various organic solvents and could tolerate 80° C in aqueous solution without loss of activity. The killing effect of fulvocin C was observed only at concentrations higher than 0.25 μmol/l. Macromolecular synthesis (DNA, RNA, protein) was affected very gradually. Viability in growing cultures decreased slowly from 100 to 25% during one generation (8 h). Cell division was affected early. After one generation v-shaped cell pairs had accumulated in the culture. Electron microscopic pictures revealed extended membrane systems connected with the inner membrane. The most striking effect was that often the outer membranes of neighbouring cells seemed to have fused laterally. With further incubation many cells lost their rod shape and empty bags became predominant.

    197. Rollenwandel und derzeitiger Stellenwert der operativen Behandlung des kleinzelligen Bronchialcarcinoms (1979)

    Description / Table of Contents: Zusammenfassung Das kleinzellige Bronchialcarcinom metastasiert früh, es wurde von der Operation ausgeschlossen. Die Chemo- und Radiotherapie sind jedoch an einer operativen Tumorverkleinerung interessiert. Bei 94 Patienten wurde diese Tumorart diagnostiziert, bei 24 wurde der Primärtumor reseziert. In allen Fällen erfolgte die weitere Therapie mit ACO und RT (Seeber). Die mittlere Überlebenszeit der Operierten liegt bei 12,0 Monaten, bei den Inoperablen bei 8,7. Nach Resektion, Chemo- und Radiotherapie läßt sich demnach auch für das kleinzellige Bronchialcarcinom eine relativ günstige Prognose stellen.
    Notes: Summary. There is early metastasis of the small cell bronchial carcinoma, and until now it has not been treated surgically. However, chemo- and radiotherapy are concerned in decreasing tumor size by surgery. This type of tumor was diagnosed in 94 patients; in 24 of these cases the primary tumor was removed. In all cases further therapy was based on ACO and irradiation (Seeber). The mean survival time of the operated patients was 12.0 months, for the inoperable ones 8.7 months. Thus, after resection, chemo- and radiotherapy, there is a comparatively favorable prognosis for the small cell bronchial carcinoma.

    A Formula for the Shaped Charge Jet Breakup-Time (1979)

    Notes: It was found that the breakup-time of jets formed by shaped charges of cylindrical symmetry is given very accurately by the formula: \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm t}_{\rm B} {\rm = }\frac{1}{{{\rm V}_{{\rm PL}} }}\sqrt {8{\rm R } \cdot {\rm T}_{\rm L} } \cdot \sin {\rm \beta /2} $$\end{document} This formula is obtained from a general principal applied here for the first time which says that the breakup-time of homogeneous ductile metals under very high strain rates is equal to the smallest initial dimension of the elongating metal divided by VPL. When applied to simple configurations such as a pipe which expands due to internal explosion this principal leads to a correct prediction of the average formed fragment dimensions. This principal provides for the first time an explanation to the experimental fact that metals' ductility can increase by an order of magnitude when the strain rate increases from 10-2 to 105 pro second.
