Bis(6′-carboxy-2,2′-bipyridine-6-carboxylato-κ3N,N′,O6)nickel(II) tetrahydrate

Triaqua[2,2′-(propane-1,3-diyl)bis(5-carboxy-1H-imidazole-4-carboxylato-κ2 N 3,O 4)]calcium(II) tetrahydrate

In the title compound, [Ca(C(13)H(10)N(4)O(8))(H(2)O)(3)]·4H(2)O, the Ca(II) ion is hepta-coordinated by two N atoms and two O atoms from a tetra-dentate 1,3-bis-(1H-imidazole-4,5-dicarb-oxy-l-ate) propane dianion and three water O atoms, giving a distorted penta-gonal-bipyramidal coordination environment. The Ca-O bond lengths are in the range 2.354 (3)-2.453 (2) Å, while the Ca-N bond lengths...

Diaqua­bis(ciprofloxacinato)manganese(II) 2,2′-bipyridine solvate tetrahydrate

In the crystal structure of the title compound {systematic name: diaquabis-[1-cyclo-propyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydro-quinoline-3-carboxyl-ato]manganese(II) 2,2'-bi-pyridine solvate tetrahydrate}, [Mn(C(17)H(17)FN(3)O(3))(2)(H(2)O)(2)]·C(10)H(8)N(2)·4H(2)O, the pyridone O and one carboxyl-ate O atom of the two ciprofloxacin ligands are bound to the Mn(II) ion and occupy the e...

Zhang 22-6

Several microcirculation patterns in tumors have been reported, including vasculogenic mimicry (VM), mosaic vessels (MV) and endothelium-dependent vessels. To investigate the sources of blood supply during different tumor stages, we studied the correlation between expression of vasculogenic mimicry (VM), mosaic vessels (MV) and endothelium-dependent vessels in a mouse melanoma xenograph. Sixty ...
