In presented work authors analyzed the high-temperature oxidation process from the point of view of its influence on effects obtained during cast iron hot-dip zinc coating. Research concerned the influence of the high-temperature oxidation, as a preliminary stage previous to coating with zinc on the change of surface layer structure as well as subsurface layer of cast iron with flake, vermicula...

OBJECTIVE MRI parameters of iron concentration (R2*, transverse relaxation rate), microstructural integrity (mean diffusivity and fractional anisotropy), as well as gray and white matter volumes were analyzed in patients with subarachnoid hemorrhage (SAH) and uncomplicated clinical course to detect the evolution of brain tissue changes 3 weeks and 12 months after ictus. METHODS MRI scans of 1...

We describe our implementation of an extremely detailed model atom of singly ionized iron for NLTE computations in static and moving astrophysical plasmas. Our model atom includes 617 levels, 13675 primary permitted transitions and up to 1.2 million secondary transitions. Our approach guarantees that the total iron opacity is included at the correct wavelength with reasonable memory and CPU req...

Iron overload causes the generation of reactive oxygen species that can lead to lasting damage to the liver and other organs. The goal of this study was to identify genes that modify the toxicity of iron overload. We studied the effect of iron overload on the hepatic transcriptional and metabolomic profile in mouse models using a dietary model of iron overload and a genetic model, the hemojuvel...

Aim: Treatment of chronic kidney disease (CKD) includes parenteral iron therapy, and these infusions can lead to iron overload. Secondary iron overload is typically treated with iron chelators, of which deferasirox is one of the most promising. However, it has not been studied in patients with CKD and iron overload. Methods: A pilot study was conducted to evaluate the pharmacokinetics and safet...

We present strong evidence for variability of the flux of the iron Kα emission line in the Seyfert 1 galaxy, NGC 3516. Two ASCA observations, separated by ∼ 1 yr, showed a marked decrease in continuum flux by ∼ 60 per cent. The flux in the broad, iron Kα line decreased by the same factor in this time period, with no evidence for changes in the line profile. The line variability is significant a...

BACKGROUND Current scientific evidence indicates that anemia in pregnancy, regardless of severity, is associated with an increased risk of maternal and fetal mortality. There is little published information about the bioavailability and bioequivalence of formulations containing both iron and folic acid. However, in vitro dissolution studies can provide important information on the likely relati...

Restless legs syndrome is a neurological disorder characterized by an urgency to move the legs during periods of rest. Data from a variety of sources provide a compelling argument that the amount of iron in the brain is lower in individuals with restless legs syndrome compared with neurologically normal individuals. Moreover, a significant percentage of patients with restless legs syndrome are ...
