    Notizen: Abstract Normal rat kidney cells, non-productively infected with the anaemia-inducing variant of Friend spleen focus-forming virus (F-SFFVA), were metabolically labelled with [2-3H]mannose. The primary translation product of the viral envelope gene (env), representing a glycoprotein with an apparent molecularM r of 55 000 (gp55), was isolated from cell lysates by immunoaffinity chromatography and purified by preparative SDS/PAGE. Radiolabelled oligosaccharides, released from tryptic glycopeptides by treatment with endo-β-N-acetylglucosaminidase H, were characterized chromatographically, by enzymic digestion and by acetolysis. The results revealed that F-SFFVA gp55 obtained from this source carried predominantly oligomannose type sugar chains with five to nine mannoses. As a characteristic feature, glycans with seven to nine mannoses contained, in part, an additional glucose residue. Although the amount of glucosylated species found was higher in F-SFFVA gp55 (about 25% of total endo-H-sensitive oligosaccharides) than in gp55 of the corresponding polycythaemia-inducing variant (F-SFFVP, 16.3%), the overall glycosylation pattern of the F-SFFVA env product closely resembled that of F-SFFVP gp55 [Strubeet al. (1988)J Biol Chem 263:3762–71]. Hence, our results demonstrate that the different intracellular processing and transport of the primary F-SFFVA env product cannot be attributed to aberrant trimming of its oligomannose type glycans.

    Details
    ISSN: 0368-492X

    Thema: Informatik
    Notizen: Aims to analyse the influence of Norbert Wiener's ideas on the social sciences and on social systems, including society as a whole. Describes Wiener's own attitudes regarding the applicability of cybernetics to social systems and his vision on the development of modern society. Highlights sociologists and political scientists who were inspired by his ideas and deals with researchers who tried to apply his ideas to social systems. Concludes by evaluating to what extent specific ideas of Wiener have impacted on the social sciences.

    Alienation, Participation and Increasing Societal Complexity (1994)
    Bingley : Emerald
    Kybernetes 23 (1994), S. 10-34 
    Details
    ISSN: 0368-492X
    Quelle: Emerald Fulltext Archive Database 1994-2005
    Thema: Informatik
    Notizen: Provides definitions of the three concepts in the title and explores their interrelationships. Distinguishes six alienation dimensions - powerlessness; meaninglessness; normlessness; social isolation; cultural estrangement; self-estrangement - and combines them with three kinds of participation: spontaneous, negative, and compensatory. Describes increasing societal complexity from a general systems perspective. Explores the psycho- and sociogenesis of unalienated as well as alienated participation. Increasing societal complexity creates new forms of alienation and participation, but also resistances of groups that feel threatened or left out by an excessively fast rate of change, which in turn threatens macro-societal stability. Those left without the means to participate in the economic or political process tend to be the alienated "negative participants"; they are generally destructive and anti-outgroup as a result of personal experiences or economic deprivation.

    A deterministic particle-method solving the linearized Boltzmann equation (1990)
    Springer

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung In [3] ist eine Partikelmethode vorgestellt, die unendlich viele Partikel benötigt. Zu ihrer numerischen Implementierung muß der numerisch relevante Träger abgeschätzt werden. Um dies zu vermeiden, führen wir über die Gasß-Integration eine a priori endliche Form ein und stellen numerische Ergebnisse für verschiedene Testbereiche vor.
    Notizen: Abstract In [3] a particle method is proposed which acts on an infinite grid. Hence, for a numerical application an estimation of the numerically relevant support is necessary. To overcome this difficulty we suggest a finite grid based on Gaussian integration formulas and present numerical results of different test examples.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Bei den beiden Affenarten Callithrix jacchus und Saguinus fuscicollis, die der gleichen Neuweltaffenfamilie der Krallenaffen angehören, wurden extrem unterschiedliche Serumascorbatspiegel gefunden, obwohl die Tiere unter identischen Bedingungen in derselben Kolonie gehalten wurden. Die14C-Ausscheidung von oral verabreichter 1-14C-AA wurde unter marginaler wie auch reichlicher Vitamin-C-Versorgung sowie unter Streßbedingungen untersucht. Zwischen niedriger und hoher Vitamin-C-Versorgung traten große Unterschiede im14C-Ausscheidungsmodus auf. Der Speziesunterschied war dabei geringer als der Unterschied zwischen individuellen Streß-/Nichtstreß-Bedingungen, aber in beiden Fällen war er gleichartig. In vergleichbaren Versuchen reagierte S. fuscicollis derart, daß ein höherer Streßzustand bei dieser Spezies angenommen werden kann.
    Notizen: Summary Recently it has been found that the two monkey species Callithrix jacchus and Saguinus fuscicollis, both belonging to the same New World monkey family Callitrichidae and held in the same colony under identical conditions, had extremely different serum ascorbate levels. To examine the ascorbic acid metabolism the14C-excretion of orally given 1-14C-ascorbic acid was studied under conditions of marginal and abundant vitamin C supply and under intentional stress. There were large differences in the mode of14C excretion between low and high ascorbate supply. The differences were smaller between stress/no stress conditions intraindividually than between the two species, but they were in the same manner. In comparable trials S. fuscicollis reacted such that a higher status of stress can be supposed in this species.

    Pulmonary aspergillus intracavitary colonization (PAIC) (1990)
    Springer
    Mycopathologia 112 (1990), S. 93-104 
    Details
    ISSN: 1573-0832
    Schlagwort(e): Aspergillus ; fungal elements
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Medizin
    Notizen: Abstract We have attempted to elucidate the natural history of pulmonary aspergillus intracavitary colonization (PAIC) based on more than 350 cases of the disease observed in the last 11 years and on data collected from the literature. The data indicate that PAIC is a dynamic process consequent to the continual growth and death of fungal elements and also with their relationships to the anatomic features of the cavity (valvular mechanisms, vascular alteration). The clinical presentations reflect immunological changes in the host. Metabolites produced by the species of Aspergillus involved affect the clinical presentation of the syndrome.

    The effect of the environment on the permeability and composition of Citrus leaf cuticles (1990)
    Springer

    Thema: Biologie
    Notizen: Abstract The water permeabilities of 3174 astomatous, isolated cuticular membranes from Citrus aurantium L. leaves were studied. Trees were grown in environmental chambers at temperatures ranging from 15 to 35° C and humidities of 50% and 90%. Photosynthetically active radiation was 500–1000 μmol photons·m−2· s−1. The different growing conditions had no effect on the water permeability of the membranes. However, storing isolated cuticular membranes at 8° C for up to 112 weeks decreased their water permeability, and it is argued that this is a consequence of the healing of defects between wax crystallites, and also indicates the dynamic nature of cuticular waxes.
