The discovery that the short-lived radionucleide Fe was present in the oldest meteorites suggests that the formation of the Earth closely followed the death of a massive star. I discuss three astrophysical origins: winds from an AGB star, injection of supernova ejecta into circumstellar disks, and induced star formation on the boundaries of HII regions. I show that the first two fail to match t...

The presented review is devoted to analytical applications of reactions of Fe(III) and K(3)[Fe(CN)(6)] with 2,10-disubstituted phenothiazines (PT). It was found that iron(III) and hexacyanoferrate(III) ions in acidic media easily oxidized PT with the formation of colored oxidation products. This property has been exploited for spectrophotometric determination of iron(III) ions and phenothiazine...

We report the development, experimental verification, and application of a general theory called [Fe]MRI (pronounced fem-ree) for the non-invasive, quantitative molecular magnetic resonance imaging (MRI) of added magnetic nanoparticles or other magnetic contrast agents in biological tissues and other sites. [Fe]MRI can easily be implemented on any MRI instrument, requiring only measurements of ...

The poor endurance of the ferroelectric (FE) HfO2 (Fe-HfO2) material-based FE field-effect transistor (Fe-FET) remains a major challenge for its future commercial production. Here we propose high-? interface seed layer (SL) in metal-FE-insulator-semiconductor (MFIS) gate stack to address this issue. We fabricated Hf0.5Zr0.5O2 (HZO) thin films on various dielectric SLs, including ZrO2, HfO2, (Hf...

Diabetes mellitus (DM) is characterized by alterations in fluid balance and blood volume homeostasis. Renal interstitial hydrostatic pressure (RIHP) has been shown to play a critical role in mediating sodium and water excretion under various conditions. The objective of this study was to determine the effects of immediate and delayed initiation of insulin treatment on the restoration of the rel...

Several radiolabelled cocaine analogues have been proposed for brain imaging of the dopamine transporter in research on neuropsychiatric disorders and drug abuse. In a recent positron emission tomography (PET) study we labelled the cocaine analogue β-CIT-FE with carbon-11 and demonstrated high specific binding in the monkey striatum. In the present study, the selectivity of [""C]β-CIT-FE bindin...

It is shown that if the Al inventory of the early solar system, taken as (Al/Al) , is a result 25 5 5 # 10 , of injection of fresh debris from a Type II supernova (SNII), then Fe/Fe would have to be between 3 # and . This inferred correlation of Al and Fe is based on the observation that both nuclei are 27 25 10 1 # 10 produced dominantly in the O/Ne zone and that for SNII ejecta Al/Fe is betwe...

Novel shape- and structural-controlled superparamagnetic nanostructures composed of self-supported spherical and rod-like CoFe(2)O(4) colloidal nanocrystals have been prepared by thermolysis of a stoichiometric Co(2+)Fe(2)(3+)-oleate complex in organic solution with periodic injection of hexane for controlling the nucleation, assembly, and growth of the nuclei.

Background: Oxidation of hepatocyte mitochondria due to iron overload led injury, elevated Transforming growth factor- β (TGF- β), and fibrosis. Fibrosis starts with stellate cell fibrogenesis activated by chronic injury. Liver fibrosis is the main cause morbidity mortality in overload. Deferasirox an chelation drug serving bind have antifibrotic effect. Aim: To examine effect deferasirox on li...
