Unraveling the Burden of Iron in Neurodegeneration: Intersections with Amyloid Beta Peptide Pathology
(Hindawi Publishing Corporation, 2018-01-31)
Iron overload is a hallmark of many neurodegenerative processes such as Alzheimer's, Parkinson's, and Huntington's diseases. Unbound iron accumulated as a consequence of brain aging is highly reactive with water and oxygen ...
Enhancing arsenic adsorption via excellent dispersion of iron oxide nanoparticles inside poly(vinyl alcohol) nanofibers
(Elsevier, 2021-02)
Superparamagnetic iron oxide nanoparticles (SPIONs) are great adsorbents of toxic arsenic in water. However, SPIONs efficiency is limited by a tendency towards agglomeration, and an extra filtering process is required in ...
Sub-chronic iron overload triggers oxidative stress development in rat brain: Implications for cell protection
(Springer, 2016-02)
This work was aimed to test the hypothesis that sub-chronic administration of iron-dextran (Fe-dextran) (six doses of 50 mg Fe-dextran/kg) to rats triggers a transient oxidative stress in brain and mechanisms of cellular ...
Confined Iron Nanoparticles on Mesoporous Ordered Silica for Fischer–Tropsch Synthesis
(Springer/Plenum Publishers, 2019-09)
Iron oxide particles were deposited in an ordered mesoporous material (SBA-15) with the aim of studying its behavior in the catalytic hydrogenation of CO (Fischer–Tropsch Synthesis). Bulk iron oxide, and iron supported on ...

Oxidation Induced Doping of Nanoparticles Revealed by in Situ X-ray Absorption Studies
(American Chemical Society, 2016-05)
Doping is a well-known approach to modulate the electronic and optical properties of nanoparticles (NPs). However, doping at nanoscale is still very challenging, and the reasons for that are not well understood. We studied ...
Nitric oxide accumulation is required to protect against iron-mediated oxidative stress in frataxin-deficient Arabidopsis plants
(Elsevier Science, 2009-01)
Frataxin is a mitochondrial protein that is conserved throughout evolution. In yeast and mammals, frataxin is essential for cellular iron (Fe) homeostasis and survival during oxidative stress. In plants, frataxin deficiency ...
Dipolar interactions among magnetic dipoles of iron oxide particles dispersed in mili-size hydrogel beads
(Elsevier Science, 2020-11-01)
The recently published Mean Field Interacting Superparamagnet Model (MFISP model), whichintroduces the effective demagnetizing factor , is tested in specimens having a random-likespatial distribution of magnetic nanoparticles, ...
Iron and mechanisms of neurotoxicity
(Hindawi Publishing Corporation, 2010-12-27)
The accumulation of transition metals (e.g., copper, zinc, and iron) and the dysregulation of their metabolism are a hallmark in the pathogenesis of several neurodegenerative diseases. This paper will be focused on the ...
Polyacrylic acid-coated iron oxide magnetic nanoparticles: The polymer molecular weight influence
(Elsevier Science, 2018-01-31)
Magnetic nanoparticles (MNPs), in particular, magnetic iron oxide-based nanoparticles were found to be useful as catalysts and as devices for data storage, environmental remediation and several biomedical applications, due ...
