The distance between the heme iron of ferrous cytochrome P-450-CAM and a fluorine label attached to the 9-methyl carbon of its substrate, (1R)-(+)-camphor, has been determined using 19F NMR. This investigation uses the Solomon-Bloembergen equation to measure the distance from a paramagnetic heme iron to a fluorine probe incorporated into a substrate that is not in fast exchange. The structural ...
The application of a magnetic field unexpectedly alters the rest potential of ferromagnetic electrodes in paramagnetic solutions of their salts. Anodic shifts of up to 60 mV in a field of 1 tesla were observed for 1 M iron electrodes in iron nitrate solution. The magnitude of the shift depends on magnetic field strength and orientation and it varies with the anion used. The shift is smaller for...
Despite being implicated as important intermediates, iron(V) compounds have proven very challenging to isolate and characterize. Here, we report the preparation of the iron(V) nitrido complex, [PhB((t)BuIm)(3)Fe(V)≡N]BAr(F24) (PhB((t)BuIm)(3)(-) = phenyltris(3-tert-butylimidazol-2-ylidene)borato, BAr(F24) = B(3,5-(CF(3))(2)C(6)H(3))(4)(-)), by one electron oxidation of the iron(IV) nitrido prec...
Due to their special physicochemical properties, iron nanoparticles offer new promising possibilities for biomedical applications. For bench to bedside translation of super-paramagnetic iron oxide nanoparticles (SPIONs), safety issues have to be comprehensively clarified. To understand concentration-dependent nanoparticle-mediated toxicity, the exact quantification of intracellular SPIONs by re...
Present review article describes main causes of chronic kidney disease a major health problem public health problem round the globe. Disease has multiple etiologies related to sequential pathophysiological stages. It has major concern with chronic changes in renal structure and that severely alter glomerular filtration rate in patients. This article explains CKD biomarkers in brief i.e., serum ...
Core losses of transformers motivate many engineers and scientists to design implement different for their specific aims. Since there exists a growing interest on high frequency applications in today’s world, optimization studies magnetic fluid core transformer (MFCT), having an easy cheap production approach applications, are considered the present paper. The desired should operate more effici...
