    Notizen: Abstract By preselection of microorganisms which preferentially attack the side chain of cholesterol we have been able to isolate a mutant of Corynebacterium spec. Chol 73 which forms 20-carboxy-pregna-1,4-dien-3-one (BNC) from cholesterol in nearly quantitative yields. The structure of this compound has been established by means of13C NMR-,1H NMR and CD spectroscopy.

    Studies on the regulation of the branched chain amino acyl-tRNA synthetases of the fungusNeurospora crassa (1980)
    Springer
    Development genes and evolution 189 (1980), S. 171-180 
    Details
    ISSN: 1432-041X
    Schlagwort(e): Amino acyl-tRNA synthetases ; Development ; Nuclear-mitochondrial interactions ; Neurospora
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Summary The specific activities of the branched chain amino acyl-tRNA synthetases from the cytosolic and mitochondrial fractions ofN. crassa were low in dormant conidia and increased during germination, reaching a maximum 8 h after inoculation. This stage of development is characterised by high rates of many other cellular activities. The increases in activity of synthetases of both cytosol and mitochondria are inhibited by cycloheximide indicating that they are synthesized on cytoplasmic ribosomes. The mitochondrial synthetases show a stimulation of their specific activity when mitochondrial RNA and protein synthesis are inhibited by either ethidium bromide or chloramphenicol suggesting that a mitochondrial translation product regulates the synthesis of the mitochondrial synthetases. The activities of amino acyl-tRNA synthetases are dependent on energy production. When respiration is uncoupled from oxidative phosphorylation, synthetase specific activities decrease although the activities of other mitochondrial enzymes like NADH-dehydrogenase increase. This phenomenon suggests that more than one mechanism regulates the synthesis of mitochondrial proteins which are formed on cytoplasmic ribosomes. The synthesis of branched chain amino acyl-tRNA synthetases ofNeurospora is neither repressed by their cognate amino acids, nor is there inhibition by the precursors of these amino acids, as has been observed in other amino acyl-tRNA synthetases of various organism includingNeurospora.

    Morphology and chronology of ischemic mucosal changes in the small intestine (1983)
    Springer
    Journal of molecular medicine 61 (1983), S. 593-599 
    Details
    ISSN: 1432-1440
    Schlagwort(e): Small intestine ; Early ischemia ; Electron microscopy
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary The morphology and chronology of an absolute ischemia was investigated on the small intestine of man and rat. It could be shown that the morphogenesis of ischemic damage to the intestinal mucosa in man does not differ from that in the rat. However, there are crucial and in therapeutic terms significant differences in the time course of the ischemic damage to the intestinal mucosa. Whereas in the small intestine of the rat, the first appreciable alterations — detachment and disruption of the lining epithelium at the villous tip — are already to be observed after absolute ischemia lasting 15 min, in the human small intestine the same lesions only occur after 4 h. A comparable complete necrosis of the small intestinal mucosa was detected in the rat after 7-h ischemia, and in man after 44-h ischemia.

    Comparative studies on physiology and taxonomy of obligately purinolytic clostridia (1984)

    ISSN: 1432-072X
    Schlagwort(e): Clostridium acidiurici ; Clostridium cylindrosporum ; Clostridium purinolyticum ; Purine metabolism ; Selenite ; Antibiogram ; DNA homology ; Taxonomy
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract Eleven strains of obligately purinolytic clostridia have been studied with respect to their assignment to the three type strains of Clostridium acidiurici, C. cylindrosporum, and C. purinolyticum. DNA/DNA-hybridization proved to be the method of choice for differentiation whereas phenotypic characteristics such as spore morphology, substrate spectra, nutritional requirements, product formation, and sensitivity against various antibiotics did not allow unequivocal identification. All strains depended on selenite for growth.

    Malignant fibrous histiocytoma of the renal capsule (1981)
    Springer
    Journal of cancer research and clinical oncology 100 (1981), S. 285-293 
    Details
    ISSN: 1432-1335
    Schlagwort(e): Malignant fibrous histiocytoma ; Renal capsule ; Erythrophago-somes
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary We report about an extremely rare case of malignant fibrous histiocytoma (MFH) of the renal capsule. The tumor is composed of fibroblast-like cells arranged in a storiform pattern and histiocyte-like cells with multinucleated giant cells, both showing no iron reaction. Characteristic of the histiocytic quality of the tumor are numerous PAS-positive intracytoplasmic droplets which can be identified as erythrophagosomes only under the electron microscope. Emphasis is put on the preoperative differential diagnosis of the tumor from renal cell carcinoma as well as on its histogenesis and prognosis.
