Measurements of seafloor asymmetry at about 360000 pairs of conjugate points along 1250 profiles across the midAtlantic Ridge (MAR) provide new constraints on models for the upwelling of the buoyant asthenosphere. The sign and amplitude of the asymmetry vary systematically and are functions of the distance between the spreading center and the location of the inferred location of maximum regiona...

NAADP is involved in the Ca response observed at fertilization in the oocytes of several species, including starfish. In this study, we have used Ca imaging and the single-electrode voltage-clamp technique with the aim to investigate whether the NAADP-mediated Ca entry in starfish oocytes discovered in our laboratory was underlain by a membrane current and whether the Ca response to NAADP requi...

atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. the present report describes a case of variation of the median nerve observed in the iranian male cadaver during routine trial dissection. there are three roots for median nerve. median nerve is formed by joining two lateral and medial cords of brachial plexus. third root of ...
