Identification of an iron–hepcidin complex [PDF]

open access: yes, 2008
Following its identification as a liver-expressed antimicrobial peptide, the hepcidin peptide was later shown to be a key player in iron homoeostasis. It is now proposed to be the 'iron hormone' which, by interacting with the iron transporter ferroportin,

Elimination of Odours from the Gaseous Phase on Cr- and Fe-modified Y-type Zeolites

open access: yesAdsorption Science & Technology, 2001
Modified NaY-type zeolites, in which a portion of the sodium ions had been exchanged for chromium(III) or iron(III) ions, were studied as adsorbents. The modified zeolites were tested with respect to the adsorption of n-butylamine or n-butylthiol via the

Reaction of hydroxyurea with iron(III) : Formation of mono- and bis(hydroxyureato)-iron(III) complexes [PDF]

open access: yesActa chimica slovenica, 2008
Complex formation reaction between iron(III) and hydroxyurea in acidic aqueous and dimethylformamide solutions were studied by UV/VIS spectroscopy, cyclic voltammetry and EPR spectroscopy. Under conditions of an excess of hydroxyurea over iron(III, mono- and bis(hydoxyureato)iron(III) complexes are formed.

Quantitative MRI Uncovers Subtle Cortical Damage in Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether myelin‐sensitive quantitative MRI reveals microstructural abnormalities in normal‐appearing cortex (NACtx) in myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), indicating that conventional MRI underestimates remission residual cortical injury.

The sequestration of phosphate by iron phases in the sediments from Lake Rotorua, New Zealand [PDF]

open access: yes, 2007
A sequential extraction method was used to determine which dominant sedimentary mineral phase was involved in phosphorus retention in the sediments of Lake Rotorua and to verify the importance of iron phases in the role as a phosphorus sink. The observed

Progressive Parkinsonism in PPP2R5D‐Related Neurodevelopmental Disorder

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT PPP2R5D‐related neurodevelopmental disorder (Houge–Janssens syndrome type 1) is a rare autosomal dominant condition characterized by macrocephaly, intellectual disability, and epilepsy. Progressive parkinsonism is an emerging adult phenotype that neurologists should be aware of since timely genetic diagnosis opens the door to disease‐modifying

Synthetic Bio-Graphene Based Nanomaterials through Different Iron Catalysts

open access: yesNanomaterials, 2018
Kraft lignin was catalytically graphitized to graphene-based nanostructures at 1000 °C under argon atmosphere with four iron catalysts, iron(III) nitrate (Fe-N); iron(II) chloride (Fe-Cl2); iron(III) chloride (Fe-Cl3); and iron(II) sulfate (Fe-S ...

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

open access: yesArthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.
