    Notes: Fork length was measured in two groups of salmon parr (32–139 mm, frozen in a straight posture and frozen in a curved posture) before (L1) and after (L2) freezing and thawing. All the fish shrank. The decrease in length was significantly greater in the curved fish than the straight fish. The absolute reduction in length (L1–L2) was related directly to L1, whereas the percentage reduction in length [(L1–L2)/L1× 100] was related inversely to L1.

    Homing movements of displaced stream-dwelling brown trout (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 50 (1997), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: In April and May of 1993, 12 of 14 brown trout (202–288 mm), tagged with radio transmitters and displaced over 800–3600 m in a natural river system, returned to the areas from which they were captured. Homing was generally directed and rapid (up to 1·22 body lengths s−1 against the flow). Homing commenced within 65 min of displacement for four of five trout displaced downstream, and within 4 days for those displaced above the confluence of a home tributary burn with the main stem of the river.

    Early development of the Drosophila mushroom bodies, brain centres for associative learning and memory (1997)

    Notes: Abstract  We have studied the formation of Drosophila mushroom bodies using enhancer detector techniques to visualize specific components of these complex intrinsic brain structures. During embryogenesis, neuronal proliferation begins in four mushroom body neuroblasts and the major axonal pathways of the mushroom bodies are pioneered. During larval development, neuronal proliferation continues and further axonal projections in the pedunculus and lobes are formed in a highly structured manner characterized by spatial heterogeneity of reporter gene expression. Enhancer detector analysis identifies many genomic locations that are specifically activated in mushroom body intrinsic neurons (Kenyon cells) during the transition from embryonic to postembryonic development and during metamorphosis.

    Genetic variation in Antarctic populations of the moss Sarconeurum glaciale (1997)
    Springer
    Polar biology 18 (1997), S. 344-350 
    Details
    ISSN: 1432-2056
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Sixty-six isolates of the moss Sarconeurum glaciale were collected from sites in continental Antarctica at Ross Island, southern Victoria Land and the Vestfold Hills. Genetic variation within and among the populations was estimated using isozymes and random amplified polymorphic DNA (RAPD) technology. Isozyme results only reproducibly showed variation between the populations with one enzyme; RAPDs indicated significantly higher levels of genetic variability within and among the Vestfold Hills samples than in the Ross Sea region samples. A dendrogram produced from the RAPD bands suggested that the Ross Island and southern Victoria Land samples form one population, and those from the Vestfold Hills form a separate and more variable population, possibly resulting from separate colonisation events on the continent.

    The influence of two types of meal on the pharmacokinetics of a modified-release formulation of nifedipine (Adalat Retard) (1997)

    Notes: Abstract Objective: The effect of two different types of meal on the absorption of a modified-release formulation of nifedipine (Adalat Retard) was studied. Results: A light breakfast produced a delay in gastric emptying (indicated by the rate of paracetamol absorption) compared with the fasting state, but did not alter the tmax or Cmax for nifedipine significantly. After a cooked breakfast, there was less delay in gastric emptying and again no delay in tmax for nifedipine. However, the Cmax for nifedipine was significantly higher than in the fasting state. Neither meal influenced the bioavailability of nifedipine. Conclusion: The results suggest that the nature of the meal has an important influence on the absorption profile of this formulation of nifedipine, probably by an effect on its dissolution. This study illustrates the importance of considering the effects of different types of meal before concluding that food does not affect the pattern of drug absorption.
