The structure of the title compound, Mn(II)[Fe(III)(CN)(6)](2/3)·5H(2)O, features a face-centered cubic -Mn-NC-Fe- framework with both Mn and Fe having site symmetry mm. Since one-third of the [Fe(CN)(6)](3-) units are missing for a given formula in order to maintain charge neutrality, each Mn atom around such a vacancy is coordinated not only by the N atoms of the CN groups but also by the O a...

Expansion of a polyglutamine tract in Huntingtin (Htt) leads to the degeneration of medium spiny neurons in Huntington's disease (HD). Furthermore, the HTT gene has been functionally linked to iron (Fe) metabolism, and HD patients show alterations in brain and peripheral Fe homeostasis. Recently, we discovered that expression of mutant HTT is associated with impaired manganese (Mn) uptake follo...

The aim of this research is to investigate the phase transformations and magnetic properties nanoparticles formed during electric arc sputtering composite Fe-Mn-C with subsequent annealing resulting in an oxygen atmosphere. As a result study, pure metals, mixed oxides, carbides, carbon nanocomposites are synthesized. susceptibility composites grows temperature increase up 600°C as compared iron...

Abstract The surface oxidation and wettability of Mn Si-alloyed steel after annealing at different conditions are studied with scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), a so-called de-wetting method. After exposure 950 °C for 1 hour in an Ar + 5 vol pct H 2 gas atmosphere dew points (DP) ranging from – 40 to 10 °C, oxides were observed along the grain boundarie...

Clostridium difficile, which inhabits the human digestive tract, is an etiological agent that causes pseudomembranous colitis and antibiotic-associated diarrhea. The oxidative stress tightly relates to its virulence, which highlights the function of its superoxide dismutase (SOD). The SOD from Clostridium difficile (SODcd) is a Mn/Fe cambialistic SOD with MnSODcd exhibiting an optimal activity ...

abstract- the effects of iron (fe) and zinc (zn) treatments on the growth and nutrient composition of chickpea were studied in a greenhouse experiment arranged in a completely randomized design. while the application of fe decreased mean shoot dry weight of chickpea, that of zn had no significant effect on chickpea shoot dry weight. increasing fe levels drastically decreased mn concentration an...

The Fe- and Mn-containing superoxide dismutases catalize the same reaction and have almost superimposable active sites. Therefore, the details of their mechanisms have been assumed to be similar. However, we now show that the pH dependence of Escherichia coli MnSOD activity reflects a different active site proton equilibrium in (oxidized) Mn(3+)SOD than the event that affects the active site pK...
