Differential participation of phospholipase A2 isoforms during iron-induced retinal toxicity. Implications for age-related macular degeneration
(Pergamon-Elsevier Science Ltd, 2012-10)
Both elevated iron concentrations and the resulting oxidative stress condition are common signs in retinas of patients with age-related macular degeneration (AMD). The role of phospholipase A2 (PLA2) during iron-induced ...
Magnetophoretic mobility of iron oxide nanoparticles stabilized by small carboxylate ligands
(Elsevier Science, 2019-10)
Iron oxide nanoparticles were synthesized by the co-precipitation method and subjected to an adsorption and functionalization process at controlled pH with five different small carboxylate ligands, namely: citrate, tartrate, ...
Effects of Nanostructure and Dipolar Interactions on Magnetohyperthermia in Iron Oxide Nanoparticles
(American Chemical Society, 2016-06)
Magnetohyperthermia properties of magnetic nanoparticle colloids are strongly affected by their intrinsic magnetic properties and dipolar interactions among themselves. The intrinsic magnetic properties are related to the ...
Yerba Mate applications: Magnetic response of powders and colloids of iron oxide nanoparticles coated with Ilex paraguariensis derivatives
(Elsevier Science, 2018-09)
A co-precipitation synthesis method was used to obtain iron oxide nanoparticles coated with Yerba Mate (Ilex paraguariensis) extract. These particles have a core–shell structure with the iron oxide phase surrounded by an ...
Design of Fe-modified mesoporous nanostructures as efficient catalysts for microwave-assisted selective oxidations of sulfides
(Elsevier Science, 2021-04-05)
Redox catalysts modified with Fe were synthesized via wet impregnation of metal species loaded on SBA-15. The influence of a number of Fe precursors with distinctive counter-ions on the deposited metal species was studied. ...

Redox dyshomeostasis in the experimental chronic hepatic overloads with iron and copper
(Elsevier Science Inc, 2019-02)
Male rats of 80–90 g were overloaded with either Fe(II) or Cu(II) for 42 days by high concentrations of FeCl2 or CuSO4 in the drinking water. The animals were fed with a commercial rodent diet of 2780 kcal/100 g. Both metal ...
Treatment of real non-biodegradable wastewater: Feasibility analysis of a zero-valent iron/H2O2process
(Elsevier, 2020-08)
Textile industries present notable environmental problems related mainly to the use and management of water resources. The application of advanced oxidation technologies (AOT) to a real and complex system was analyzed. The ...
