    Reaction of monosaccharides with proteins: possible evolutionary significance (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-07-10
    Description: Measurements were made of the rate of condensation of various monosaccharides with amino groups of hemoglobin to form Schiff base linkages. The reactivity of each sugar was dependent on the extent to which it exists in the open (carbonyl) structure rather than in the ring (hemiacetal or hemiketal) structure. Among the 15 monosaccharides tested, aldoses showed higher reactivities than ketoses. Glucose was the least reactive of the aldohexoses. The emergence of glucose as the primary metabolic fuel may be due in part to the high stability of its ring structure which limits potentially deleterious nonenzymatic glycosylation of proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bunn, H F -- Higgins, P J -- AM-18223/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Jul 10;213(4504):222-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of the Howard Hughes Medical Institute, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12192669" target="_blank"〉PubMed〈/a〉

    Influence of the carbohydrate moiety on the growth inhibitory activity and adhesiveness of 3T3 cell plasma membranes (1989)
    Springer
    Cellular and molecular life sciences 45 (1989), S. 370-372 
    Details
    ISSN: 1420-9071
    Keywords: 3T3 cell ; growth inhibition ; glycosidase ; plasma membrane

    Topics: Biology , Medicine
    Notes: Summary Treatment of 3T3 cell plasma membranes with glycosidase enzymes decreased their ability to inhibit cell growth and also decreased their binding to 3T3 cells. This suggests that carbohydrate is required for complete function of inhibitory activity and that inhibition is associated with membrane adhesion.

    The histochemistry of muscle in juvenile Atlantic salmon, Salmo solar L. (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 37 (1990), S. 0 
    Details

    Topics: Biology
    Notes: In fry, 1- and 2-year old juvenile Atlantic salmon, relatively small superficial red muscle fibres staining well for glycogen and succinic dehydrogenase (SDH) but with little myofibrillar ATPase, were evident on either side of the lateral line, in June. Well differentiated relatively large white fibres contained lower concentrations of glycogen than the red fibres, higher ATPase and no SDH, except traces in the larger 1- and 2-year-olds. Intermediate size pink fibres, which were also intermediate between red and white fibres in their staining properties, occurred in a thin diffuse layer along the red-white boundary, thickest at the apex near the vertebral column, and most evident in the younger fish.

    Hyperplasia and hypertrophy in the growth of skeletal muscle in juvenile Atlantic salmon, Salmo salar L. (1990)

    Notes: Both red and white muscle fibre numbers in juvenile Atlantic salmon increased gradually with fish length throughout the freshwater growth period. Mean fibre area increased as fish grew to 6.5 cm f.l., but thereafter was unrelated to fish length. Hyperplasia was most obvious when fish were growing fastest, and was the dominant growth process in fish over 6.5 cm f.l. Hypertrophy was most important when growth was slow, as in autumn and winter.Mean white fibre area was significantly smaller in deep muscle than at medial and superficial sites. Total cross-sectional area of red, white and total trunk muscle increased with fish length. The ratio of red: white cross-sectional area increased with fish length to a plateau at about 10% after 6.5 cm f.l.

    Movement rhythms in juvenile Atlantic salmon, Salmo salar L. (1988)

    Notes: Nocturnal downstrean migration of juvenile Atlantic salmon is usually interpreted as increased locomotor activity. The frequency of downstream passages of 0–1 + salmon in an endless stream channel was greater by night than by day in both smoking and non-smolting fish in autumn and spring. Movement increased at dusk, and decreased after dawn. Mature male 1 + fish moved slightly less than immatures in October, but significantly more in November. Total movement frequency was lower at full moon than at other moon phases, and movement was reduced when the moon was up. Under turbid conditions by day, the threshold water velocity inducing nett downstream movement was 8.2 cm s−1, and the relative velocity of fish swimming downstream was never more than one third that of fish holding station at the normal maximal flow of 25–30 cm s−1.At the end of their first growing season in October, fish which had been offered food continuously through 24 h did not differ in size from those fed by day only, but the latter were significantly larger than those offered food only at night.We conclude that: (1) the fish fed actively by day, and not by night; (2) station-holding represented activity, and downstream nocturnal movement represented relative inactivity (displacement) which occurred on loss of visual orientation, hence migration resulted from reduced activity; (3) lack of displacement in early autumn has adaptive value for maturing fish, but not for non-spawners.

    Effects of pre- and post-prandial starvation on meal size and evacuation rate of juvenile Atlantic salmon, Salmo salar L. (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 25 (1984), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: After a pre-prandial period of starvation or feeding with unlabelled food, 0+ salmon parr (0.8–11.7 g) were fed a test meal of iron particle labelled food and subsequently were again either starved or fed unlabelled food. The quantity of labelled food consumed and the evacuation rate was determined by serial radiographs. In fish of all sizes, pre-prandial starvation causes a larger test meal (as a percentage of body weight) to be consumed when compared to pre-prandially fed fish. In addition, pre-prandial starvation results in relatively larger meals as a percentage of body weight being taken by smaller compared to larger fish. This result was not evident for pre-prandially fed fish. Evacuation rate was unrelated to body size irrespective of feeding history. Post-prandial starvation decreased evacuation rate but this effect was inversely related to the quantity of food consumed. Larger meals were not evacuated differently from smaller meals if feeding occurred post-prandially, irrespective of pre-prandial starvation.

    A radiographic method for feeding studies on fish using metallic iron powder as a marker (1983)

    Topics: Biology
    Notes: A novel method for studying trophic dynamics of fish is described which involves X-raying animals which have been fed a diet labelled with metallic iron powder. Results of feeding studies on juvenile Atlantic salmon, Salmo salar L., are presented which demonstrate that food consumption and gastric evacuation rates can be measured without incurring the major disadvantages offeree feeding, starvation or autopsy which are associated with most of the established methods.

    Observations on the gall bladder of juvenile Atlantic salmon Salmo salar L., in relation to feeding (1982)

    Notes: Measurements of gut contents and changes in the volume and colour of bile in the gall bladder of juvenile Atlantic salmon are described for a variety of feeding regimes. The gall bladders of actively feeding fish are virtually empty of bile. When deprived of food, the weight of the gall bladder increases within 6 h and reaches a value equivalent to approximately 20% of the liver weight within 36 h. Bile is pale straw, green and blue in colour after 1, 4 and 6 days of starvation respectively. Stored bile is released from the gall bladder in response to food entering the anterior hind gut.
