TL;DR: It is proposed that the outer surface of the protein inhibits the development of MnOOH nuclei in bulk solution whereas the inner surface is inactive, enabling nucleation and growth to proceed unperturbed within the cavity.

TL;DR: In this paper, the role of zinc on hydroxylapatite (HA) crystallization was investigated using X-ray diffraction and spectrophotometric analysis, showing that zinc cannot substitute for calcium in HA structure.

TL;DR: The antibacterial and antifungal properties of five 2,6-diacetylpyridine bis(acylhydrazones) and of a series of metal complexes were investigated and the genotoxic properties of the ligands disappeared in the complexes.

TL;DR: The structural and spectroscopic properties of a new copper (II) complex of cinoxacin (HCx) have been investigated, showing the same antimicrobial activity as the corresponding ligand.

TL;DR: In vitro test of susceptibility of Fe(III)- and Zn(II)-complexes showed stronger activity than that of norfloxacin against G(-) E.Coli and Bacillus dysenteriae bacteria.

TL;DR: In this article, a comparison of solid-state structures determined by X-ray crystallography with 27Al NMR spectra offers a means of determining which species are important components in the solution state.

TL;DR: The structure determination of CPO was undertaken to help elucidate those structural features that enable the enzyme to exhibit these multiple activities of peroxidase, catalase and cytochrome P450-like activities in addition to catalyzing halogenation reactions.

TL;DR: In this paper, the preparation, spectroscopic, magnetic properties, and crystal structure of [Cu(stzxpy) 3 Cl] (stz − stands for the deprotonated form of sulfathiazole, 4-amino-N-2-thiazolylbencenosulfonamide) are reported.

TL;DR: The EPR spectra of the membrane fraction of Methylococcus capsulatus Bath are correlated with the amount of copper present in the membranes and to the activity of the pMMO as measured by the production of propylene oxide from propene by the pPMMO.

TL;DR: Several of the M2+ appeared to bind strongly to the phosphate-free mineral core surface in reconstituted HoSF, a result directly attributable to the presence of phosphate binding sites.

TL;DR: In this article, two types of anionic light and thermally stable Ag(I) complexes with remarkable antimicrobial activities for bacteria, yeast, and mold have been characterized with complete elemental analyses, TG/DTA, FT-IR, and ESCA spectra.

TL;DR: Biological studies have shown that the ligands and the complexes Zn(daptsc)Cl2 have an effect in vitro on cell proliferation and differentiation (inhibition); both are concentration dependent.

TL;DR: Equilibrium study on the mixed-ligand complex formation of M2+ ions with alpha-d-(-)aminobenzyl penicillin popularly known as ampicillin and nucleic bases and stability constants of the ternary complexes.

TL;DR: The superoxide dismutase mimetic activity of a copper(II) complex with the tetraazamacrocyclic ligand TAAB has been investigated using the xanthin-xanthine oxidase system for generation of superoxide.

TL;DR: Ru(II), Cu(II, and Mn(II) complexes of an unsymmetrical macrocycle Mc containing pyrazole and amine nitrogen atoms as donor sites have been synthesized and studied in the solid state and in solution as discussed by the authors.

TL;DR: Denaturation measurements of free HSA and HSA in the presence of dirhodium(II) acetate complex with 8-M urea followed by CD spectroscopy, suggest that rhodium affects the secondary protein structure and might stabilize HSA against denaturing agents.

TL;DR: Results of simulated plasma copper distributions virtually rule out any quantitative influence of salicylate on copper tissue diffusion at therapeutic levels, and the assertion that copper-NSAID complexes represent the active forms of NSAIDs therefore seems to be of limited significance for saliylate.

TL;DR: Higher precision X-ray powder diffraction now indicates that the PIC core has a long-range order more similar to the mineral akaganéite, beta-FeOOH, than to ferrihydrite, which has been found for other similar ferric iron-carbohydrate polymers.

TL;DR: The interaction of iron(III) with different anionic polyssacharides has been studied by pH-metric, UV-vis, Fourier transform infrared, viscometric, and conductometric methods as discussed by the authors.

TL;DR: The possible participation of Mg(II) in the mechanism of toxicity of tetracycline is suggested and the formation of the MHL and M2L species in which an M g ion is coordinated to the C11 and C12 oxygens of the BCD ring system is suggested.

TL;DR: It is concluded that a small conformational change in the protein was induced by Al3+ binding to apo-transferrin, indicating that Al3- cannot displace Fe3+ under the experimental conditions employed.

TL;DR: The interaction of LPO with its native substrate (the thiocyanate anion), which previously was shown by NMR and EPR (at high substrate concentration) spectroscopies, has been confirmed by EPR at low temperature and low substrate concentration and by optical spectroscopy at room temperature and high substrate concentrate as a function of pH.

TL;DR: A long-lived chromium(IV) intermediate is generated during the reaction between Cr(VI) and glutathione in glycine below pH 3.4, offering an opportunity to examine the mechanism of DNA damage by this rare oxidation state.

TL;DR: Complex formation between oxovanadium(IV) and vanadate(V) with deferoxamine B was investigated in aqueous solution by EPR, electronic absorption spectroscopy, 51V NMR, ans pH-potentiometry as mentioned in this paper.

TL;DR: The electrochemical behavior, investigated by cyclic voltammetry, shows that the complex possesses a very high redox stability and the possible SOD-like activity was tested using the NBT/superoxide reduction assay, showing a negligible SOD activity.

TL;DR: None of the compounds showed genotoxicity in the Bacillus subtilis rec-assay and in the Salmonella-microsome test, and the in vitro evaluation of antimicrobial properties revealed the strong activity of Sn (C6H5)2(Hdpa)Cl2 and Sn(C6 H5)3Cl(OH2).

TL;DR: In this paper, an injectable iron dextran complex used as a hematinic has been studied using Mossbauer spectroscopy (18-295 K) and x-ray powder diffraction.
