To evaluate the influence of inhibitors of prostaglandin synthesis on the incidence of DMH-induced colon cancer, 90 male Sprague-Dawley rats were randomly assigned to: indomethacin 20 mg per liter drinking water, meclofenamate 50 mg per liter drinking water, or normal drinking water (control group). Dimethylhydrazine was given by weekly subcutaneous(More)
The use of kinetically robust chromium(III) fluorido complexes as synthons for mixed 3d-4f clusters is reported. The tendency toward linear {Cr(III)-F-Ln(III)} units dictates the cluster topology. Specifically, we show that reaction of cis-[Cr(III)F(2)(NN)(2)]NO(3) (NN = 1,10-phenanthroline ("phen") or 2,2'-bipyridine ("bpy")) with Ln(NO(3))(3)·xH(2)O(More)
In the solid state, MnF(salen) forms chains wherein fairly linear fluoride bridges between high-spin Mn(III) centers are observed. We interpret the magnetic properties of these chains by use of the classical Fisher model and by use of the high-temperature expansion approach, as well as by exact matrix diagonalization of the spin Hamiltonian, of model rings.(More)
The title complex, [CrF(2)(C(12)H(8)N(2))(2)]ClO(4)·H(2)O, displays a slightly distorted octa-hedral coordination geometry around the central chromium(III) ion. The Cr environment is composed of a cis arrangement of two 1,10-phenanthroline [average Cr(III)-N = 2.0726 (10) Å] and two fluoride [average Cr(III)-F = 1.8533 (6) Å] ligands. The water molecule(More)
