    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] For analysis, therefore, 20-1. samples were utilized. A known amount of niobium-95 was added to each sample, and the radioactivity of an aliquot assayed. To the remainder was added 175 fJtgm. of ferric iron. The pH. was adjusted to 9 -9-10 -0 by the slow addition of ammonia with constant stirring. ...

    Activation of Hormonal Secretions: A Crustacean Chromactivator (1958)
    [s.l.] : Nature Publishing Group
    Nature 182 (1958), S. 33-34 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IT is an old observation that colour change of Crustacea is brought about by the action of certain chromactivating substances, the best known of which are released into the blood by the sinus gland of the eye-stalk. In 1955, Knowles, Carlisle and Dupont-Raabe1, working on Leander serratus, showed ...

    Niobium in Ascidians (1958)
    [s.l.] : Nature Publishing Group
    Nature 181 (1958), S. 933-933

    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] In the course of some other work I was led to the conclusion that some of these species of ascidians may possibly contain niobium in place of, or in addition to, vanadium. This has in fact proved to be correct. Preliminary analyses have kindly been made for me by the Chemical Research Laboratory of ...

    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] (3) These hormones control the relatively rapid and repeat able actions of effector organs. They form a very distinct group, for which we propose the term 'kinetic', since no other name has been generally accepted. They include oxytocin and other hormones acting on muscles, chromactivating ...

    Notes: [Auszug] Tubes of the four species available withstood treatment for 20 min. in saturated aqueous potassium hydroxide at 150 C. The alkali-treated tubes, after washing, were coloured brown by iodine in potassium iodide solution, becoming violet when this was replaced by dilute sulphuric acid4. ...

    Notes: [Auszug] The neural glands were ground with sand in acetone and hydrochloric acid to pH. c. 1-0 in such volume that the final liquid contained 15 per cent water. The debris was filtered off and enough acetone added to the filtrate to reduce the water content to 4-6 per cent. A precipitate was formed which ...

    Notes: [Auszug] Calanus finmarchicus and C. helgolandicus pass through three generations a year, in southern populations at least, overwintering as the last larval instar (the fifth copepodid stage)8. It has recently been shown (Smyly, W. J. P., personal communication) that Cyclops leuckarti has a similar ...

    A Hermit Crab New to Britain (1961)

    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] C. misanthropus is a hermit crab with subequal claws and hence quite unlike any of the native species which have unequal claws. It seems likely that it was not present on this shore before the winter of 1959-60, to judge by the reports of amateur collectors in this region, nor has it been found on ...

    Notes: [Auszug] During an endocrinological investigation of two species of locusts, Locusta migratoria migratorioides (R. and F.) and Schistocerca gregaria (Forsk.), we observed that the prothoracic gland (ventral gland) is shaped differently and significantly larger in solitary than in gregarious individuals ...

    Notes: [Auszug] Joly et al. have shown3 that in this species the prothoracotropic hormone of the brain stimulates the prothoracic gland (in the nymphal instars) about 48 h after the preceding moult. The new moult thus initiated occurs about 4 days later. Injection with a brain homogenate 24 h after a moult leads ...
