    Glutathione Peroxidase Activity During Storage of Fish Muscle (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 61 (1996), S. 0 
    Details
    ISSN: 1750-3841

    Notizen: Activity of fish muscle glutathione peroxidase, which presumably protects muscle from oxidative deterioration during storage and processing, was found in both Japanese jack mackerel and skipjack tuna. Activity of the peroxidase and level of reduced glutathione (enzyme substrate) decreased during 5 days storage at 4°C. Lipid hydroperoxides were substantially formed in the fish muscles during the storage.

    Cytokeratin immunolocalization and lectin binding studies in oesophageal squamous dysplasia (1996)
    Oxford, U.K. and Cambridge, USA : Blackwell Science Ltd
    Histopathology 29 (1996), S. 0

    Notizen: We examined full thickness specimens of oesophageal squamous dysplasia from both cancer-free and cancer patients using immunohistochemical labelling for cytokeratin subtypes 10/13 and 14 and for involucrin, binding studies for various lectins, and PAS/D staining before and after diastase treatment. We studied specimens from patients with oesophageal carcinoma (52 normal epithelia, and 49 with mild, 38 with moderate, and 32 with severe dysplasia), and 32 specimens from cancer-free patients (five normal epithelia and 16 with mild and 11 with moderate dysplasia). Abnormal cytokeratin expression patterns in atypical cells, i.e. both cytokeratin 10/13 and cytokeratin 14 immunoreactivity in the same cells was detected in 41 of 99 specimens with dysplasias in cancer patients. Helix aspersaErythrina cristagalli and Robinia pseudoacacia binding was consistently negative in atypical cells in squamous dysplasia. The non-atypical layer of squamous dysplasia, which was morphologically indistinguishable from the corresponding layer of normal oesophageal squamous epithelium, showed abnormal involucrin expression in 39/101 specimens, Helix aspersa binding in 74/106, diastase sensitive PAS staining in 52/110, Erythrina cristaglli binding in 28/107, and Robinia pseudoacacia binding in 16/100. There were no significant differences in the expression of these markers in dysplasia between cancer patients and cancer-free individuals with the exception of increased Robinia pseudoacacia binding in the non-atypical layer in cancer-free patients. The results indicate that abnormal patterns of cytokeratin expression and lectin binding occur not only in atypical cells but also in non-atypical cells in oesophageal squamous dysplasia.

    Comments on the characteristics of incommensurate modulation in quartz: discussion about a neutron scattering experiment (1999)
    [S.l.] : International Union of Crystallography (IUCr)
    Acta crystallographica 55 (1999), S. 65-69 
    Details
    ISSN: 1600-5724

    Notizen: From analysis of the elastic neutron scattering data of Dolino et al. [J. Phys. (Paris) (1984), 45, 361–371], it is shown that, besides the well identified components u_x and u_y of the acoustic displacements in the incommensurate (IC) phase of quartz, there also exists a strong component of the u_z vector of the modulation. The existence of the large u_z is not consistent with the currently accepted model for the IC transition in quartz, since the long-period IC modulation observed in quartz cannot induce any noticeable acoustic component u_z. The need for a new model is keenly felt in order to understand the origin of the IC modulation in quartz.

    Expression of intercellular adhesion molecule-1 (ICAM-1) on vascular endothelial cells and renal tubular cells in the generalized Shwartzman reaction as an experimental disseminated intravascular coagulation model (1997)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS immunology and medical microbiology 18 (1997), S. 0 
    Details
    ISSN: 1574-695X
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie , Medizin
    Notizen: The participation of adhesion molecules in systemic vascular injuries of the generalized Shwartzman reaction was studied. The generalized Shwartzman reaction was induced in mice by two consecutive injections of lipopolysaccharide. Intercellular adhesion molecule-1 (ICAM-1) was expressed on vascular endothelial cells, renal tubular cells and alveolar wall in generalized Shwartzman reaction-induced mice. The preparative injection of lipopolysaccharides induced ICAM-1 expression in those cells, and the provocative injection of lipopolysaccharides for the generalized Shwartzman reaction augmented it further. The simultaneous administration of anti-gamma interferon antibody with the preparative injection of lipopolysaccharides completely inhibited ICAM-1 expression on vascular endothelial cells. The injection of recombinant gamma interferon in replacement of lipopolysaccharides resulted in ICAM-1 expression. The administration of anti-ICAM-1 antibody together with the provocative injection of lipopolysaccharides significantly blocked the apoptosis of vascular endothelial cells in generalized Shwartzman reaction-induced mice. It was suggested that ICAM-1 expression on vascular endothelial cells might be involved in systemic vascular injuries of the generalized Shwartzman reaction, and that it might be regulated by gamma interferon.

    Apoptotic cell death of vascular endothelial cells and renal tubular cells in the generalized Shwartzman reaction (1996)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS immunology and medical microbiology 16 (1996), S. 0

    Notizen: Abstract The participation of apoptotic cell death in the generalized Shwartzman reaction was examined. The generalized Shwartzman reaction was induced in mice by two consecutive injections of lipopolysaccharide. Vascular endothelial cells in various organs of those mice were stained positively by the in situ specific labeling of fragmented DNA. Renal tubules were also stained focally. It was suggested that apoptotic cell death might participate in the development of vascular endothelial cell damage and acute tubular necrosis in the generalized Shwartzman reaction. Simultaneous administration of anti-γ-interferon antibody in the preparative injection of lipopolysaccharide completely blocked apoptosis of vascular endothelial cells. Priming with recombinant γ-interferon instead of lipopolysaccharide could produce apoptosis of vascular endothelial cells. It was suggested that γ-interferon might play a critical role on sensitization of endothelial cells for apoptosis.

    Cryptococcus nodaensis sp nov, a yeast isolated from soil in Japan that produces a salt-tolerant and thermostable glutaminase (1999)

    Notizen: An anamorphic basidiomycetous yeast, which produced a salt-tolerant and thermostable glutaminase, was isolated from soil in Japan and classified in the genus Cryptococcus. Its substrate specificity suggests that this enzyme is an L-glutaminase asparaginase (EC 3.5.1.38). The strain, G60, resembles Cryptococcus laurentii in the taxonomic criteria traditionally employed for yeasts, however it can be distinguished as a separate species based on DNA–DNA reassociation experiments and sequence analysis of the large sub-unit rDNA. Phenotypically, the isolate can be differentiated from C. laurentii by the inability to utilize arbutin as a sole source of carbon. Based on sequence analysis, the strain is related to a group of hymenomycetous yeasts including Bulleromyces albus, Bullera unica, C. laurentii and C. skinneri. The strain, which is formally described as Cryptococcus nodaensis, is industrially important for the formation of the umami taste during production of proteolytic seasonings.

    Notizen: Abstract We parametrize the space of isometric immersions of the hyperbolic n -space into the hyperbolic ( n +1)-space by a family of properly chosen (at most) countable n -tuples of real-valued functions. This is an answer to the problem posed by Nomizu in 1973. We also construct a one-parameter family of deformable isometric immersions from the quotient spaces of the hyperbolic 2-plane modulo and some totally discontinuous subgroups of isometries.
