To explain the unusual distribution of Kuiper belt objects, several authors have advocated the existence of a super-Earth planet in the outer solar system. It has recently been proposed that a 10 M⊕ object with an orbit of 700 AU semi major axis and 0.6 eccentricity can explain the observed distribution of Kuiper belt objects around Sedna. Here...

The current knowledge of Mercury's orbit has mainly been gained by direct radar ranging obtained from the 60s to 1998 and by five Mercury flybys made with Mariner 10 in the 70s, and with MESSENGER made in 2008 and 2009. On March 18, 2011, MESSENGER became the first spacecraft to orbit Mercury. The radioscience observations acquired during the...

The evolution of a primary culture of rabbit kidney cortical collecting tubule was followed over a period of 10 to 11 days. The cell types of this segment were characterized by using monoclonal antibodies, specifically directed against principal (Mab 703) and intercalated (Mab 503) cells of the apical membrane. The activity of a H+ pump ATPase...
