    Blood viscosity in diabetic children (1971)
    Springer
    Diabetologia 7 (1971), S. 461-462

    ISSN: 1432-0428
    Schlagwort(e): Diabetes mellitus ; juvenile diabetes ; blood viscosity

    Thema: Medizin
    Beschreibung / Inhaltsverzeichnis: Résumé La viscosité du sang total chez des enfants diabétiques est légèrement augmentée, par rapport à des témoins normaux adultes, quand la glycémie est augmentée. L'augmentation est indépendante de l'hématocrite et est probablement due à des facteurs situés dans le plasma et non dans les érythrocytes. Une étude de longue durée de ces patients montrerait si ces résultats ont une signification clinique ou non.
    Kurzfassung: Zusammenfassung Die gesamte Blutviskosität ist bei diabetischen Kindern, verglichen mit normalen, erwachsenen Kontrollpersonen leicht erhöht, wenn der Blutzucker erhöht ist. Die Erhöhung ist vom Hämatokrit unabhängig und wird wahrscheinlich von Plasmafaktoren und nicht von den Erythrozyten verursacht. Ob diese Befunde klinische Bedeutung haben oder nicht, wird sich bei Longitudinalstudien dieser Patienten zeigen.
    Notizen: Summary The whole blood viscosity in diabetic children compared with normal adult controls is slightly increased when the blood sugar is increased. The increase is independent of the haematocrit, and is probably caused by factors in the plasma and not in the erythrocytes. Whether or not these findings are of clinical significance will be shown by a longitudinal study of these patients.

    Sink or swim? Copepod population maintenance in the Columbia River estuarine turbidity-maxima region (1997)
    Springer
    Marine biology 129 (1997), S. 309-317 
    Details

    Thema: Biologie
    Notizen: Abstract Maintenance of estuarine zooplankton populations in large river-dominated estuaries with short residence times has been an intriguing subject of investigation. During three different hydrological seasons, autumn 1990, summer 1991, and spring 1992, we intensively sampled zooplankton populations in the estuarine turbidity maxima (ETM) region of the Columbia River estuary of Oregon and Washington, USA. One of the principal objectives was to investigate retention mechanisms of the predominant zooplankton species, the harpacticoid copepod Coullana canadensis and the epibenthic calanoid copepod Eurytemora affinis. In the ETM, C. canadensis densities mirrored those of turbidity gradients and were almost always greater at the river bed, while E. affinis densities were greater higher in the water column during the flood and lower in the water column during the ebb. Cross-correlation and time-series analyses determined that C. canadensis densities were highly positively correlated with turbidity and that most of the variability was explained by the lunisolar diurnal (K1) and principal lunar (M2) tidal components occurring once every 23.93  h and once every 12.42 h, respectively. This indicates that C. canadensis populations are most probably maintained in the estuary through the same near-bottom circulation features that trap and concentrate particles in the ETM. In contrast, densities of the more motile species E. affinis were highly correlated with negative velocities, or ebb tide, and most of the variability in population densities could be explained by the principal lunar tidal component; therefore, we hypothesize that this species is probably vertically migrating on a tidal cycle into different flow layers to avoid population losses out of the estuary.

    Limitation of life support: Frequency and practice in a London and a Cape Town intensive care unit (1996)

    Notizen: Abstract Objectives To examine the frequency of limiting (withdrawing and withholding) therapy in the intensive care unit (ICU), the grounds for limiting therapy, the people involved in the decisions, the way the decisions are implemented and the patient outcome. Design Prospective survey. Ethical approval was obtained. Setting ICUs in tertiary centres in London and Cape Town. Patients All patients who died or had life support limited. Interventions Data collection only. Results There were 65 deaths out of 945 ICU discharges in London and 45 deaths out of 354 ICU discharges in Cape Town. Therapy was limited in 81.5% and 86.7% respectively (p=0.6) of patients who died. The mean ages of patients whose therapy was limited were 60.2 years and 51.9 years (p=0.014) and mean APACHE II scores 18.5 and 22.6 (p=0.19) respectively. The most common reason for limiting therapy in both centres was multiple organ failure. Both medical and nursing staff were involved in most decisions, which were only implemented once wide consensus had been reached and the families had accepted the situation. Inotropes, ventilation, blood products, and antibiotics were most commonly withdrawn. The mean time from admission to the decision to limit therapy was 11.2 days in London and 9.6 days in Cape Twon. The times to outcome (death in all patients) were 13.2 h and 8.1 h respectively. Conclusions Withdrawal of therapy occurred commonly, most often because of multiple organ failure. Wide consensus was reached before a decision was made, and the time to death was generally short.

    The effects of feeding by Oniscus asellus on leaf litter sulfur constituents (1987)

    Notizen: Summary Feeding by the isopod, Oniscus asellus, produced changes in the sulfur constituents of leaf litter substrates (Acer negundo, A. saccharum, Fagus grandifolia, Picea rubens, and Tsuga canadensis). Isopod consumption of leaf litter generally accelerated the mineralization of carbon-bonded S and increased the formation of ester sulfate in all substrates. After the isopod egestion of A. negundo leaves, fecal decomposition over 6 weeks increased total S concentration from 68 to 120 μmol S/g due to the catabolism of organic carbon. During the same period sulfate decreased from 34 to 20 μmol S/g and carbon-bonded S increased from 34 to 100 μmol S/g. Thus the total S pool in aged feces became enriched with organic S (83% of total S). Macroinvertebrate consumption accelerated the transformation of S constituents and the carbon-bonded S concentration approached that of the Oa organic horizon of a northern hardwood forest.
