Redetermination of Fe2[BP3O12]

Explorations of phases in the quaternary Fe(III)-B(III)-P(V)-O system prepared by the high temperature solution growth (HTSG) method led to single-crystal growth of anhydrous diiron(III) borotriphosphate, Fe(2)[BP(3)O(12)]. This phase has been synthesized previously as a microcrystalline material and its structure refined in space group P3 from powder X-ray diffraction data using the Rietveld m...

Thermoelasticity of Fe2+-bearing bridgmanite

We present local density approximation augmented by the Hubbard-type correction calculations of high-temperature elastic properties of bridgmanite with composition (Mg(1−x)Fe x )SiO3 for 0≤×≤0.125. Results of elastic moduli and acoustic velocities for the Mg end-member (x=0) agree very well with the latest high-pressure and high-temperature experimental measurements. In the iron-bearing system,...

BINDING OF Fe2+ BY MAMMALIAN FERRITIN

An average of 140 Fe 2 + ions bind to mammalian ferritin that has an average core content of 1876 Fe+ ions per molecule. The Fe2+ ions enter the protein interior and exchange electrons with the core Fe+ ions. A non-homogeneous model for the iron-eontaining core of ferritin is proposed.

Fe2+-induced lysis and lipid peroxidation of chromaffin granules.

Chromaffin granules, the catecholaminergic storage granules from adrenal chromaffin cells, lysed in 10(-9)-10(-7) M Fe2+. Lysis was accompanied by the production of malondialdehyde which results from lipid peroxidation. Both chromaffin granule lysis and malondialdehyde production were inhibited by the free radical trapping agent butylated hydroxytoluene but not by catalase and/or superoxide dis...
