    N-body simulations of gravitational dynamics

    Full text link
    We describe the astrophysical and numerical basis of N-body simulations, both of collisional stellar systems (dense star clusters and galactic centres) and collisionless stellar dynamics (galaxies and large-scale structure). We explain and discuss the state-of-the-art algorithms used for these quite different regimes, attempt to give a fair critique, and point out possible directions of future improvement and development. We briefly touch upon the history of N-body simulations and their most important results.Comment: invited review (28 pages), to appear in European Physics Journal Plu

    Effect of octreotide on circulating IGF-I chromatographic profile: evidence for an inhibitory action on the formation of the 150-kDa ternary complex

    No full text
    The increasing use in clinical practice of octreotide (a somatostatin analogue which inhibits the secretion of GH and other peptide hormones) led us to study the effects of this treatment on GH, insulin-like growth factors (IGF)-I and II and IGF-binding protein (IGFBP)-3, as well as on circulating IGFBP complexes in acromegalic patients
