Rat Brain Damage due to Iron and Copper Toxicity
(Austin Publications, 2017-06)
Brain damage is associated to oxidative stress in iron (Fe) and copper (Cu) overloads in rats, in a dose- and time-dependent accumulation of the metals in the organ. The generation of singlet oxygen in brain measured in ...
Oxidative Stress and Genomic Damage Induced In Vitro in Human Peripheral Blood by Two Preventive Treatments of Iron Deficiency Anemia
(Humana Press, 2019-08)
Iron deficiency is the most prevalent nutritional deficiency and the main cause of anemia worldwide. Since children aged 6–24 months are among the most vulnerable groups at risk, daily supplementation with ferrous sulfate ...
Controlling the morphology and pore size of mesostructured silica nanoparticles: the role of iron oxidation state
(Royal Society of Chemistry, 2013-08)
We demonstrate morphology and pore size dependence of silica nanoparticles (SNPs) synthesized via control of the iron oxidation state. In the absence of any Fe species, only spherical SNPs are produced, whereas in the ...
Brain oxidative stress in the chronic overloads of iron and copper in rats.
(Elsevier Science Inc, 2019-12)
Male rats of 80–90 g that were fed 42 days with a commercial rodent diet of 2780 kcal/100 g and received chronic overloads of either Fe(II) or Cu(II) in the drinking water. The two metals produced brain oxidative stress ...
On the Possible Significance of High Free Iron Oxide Content in Mabí Clay, a Vertisol from East-Central Puerto RicoTítulo en español.
(University of Puerto Rico Mayagüez Campus Agricultural Experiment Station, 1968)
Iron-Induced Oxidative Injury Differentially Regulates PI3K/Akt/GSK3β Pathway in Synaptic Endings from Adult and Aged Rats
(Oxford University Press, 2009-10)
In this work we study the state of phosphoinositide-3-kinase/Akt/glycogen synthase kinase 3 beta (PI3K/Akt/GSK3 beta) signaling during oxidative injury triggered by free iron using cerebral cortex synaptic endings isolated ...
Intravenous iron sucrose reverses anemia-induced cardiac remodeling, prevents myocardial fibrosis, and improves cardiac function by attenuating oxidative/nitrosative stress and inflammation
(Elsevier Ireland, 2016-06)
Background: According to recent clinical trial data, correction of iron deficiency with intravenous (i.v.) iron has favorable outcomes on cardiac function. We evaluated whether i.v. iron treatment of anemic rats has favorable ...
Iron-sulfur repair YtfE protein from Escherichia coli: Structural characterization of the di-iron center
(Springer, 2008-06)
YtfE was recently shown to be a newly discovered protein required for the recovery of the activity of iron-sulfur-containing enzymes damaged by oxidative and nitrosative stress conditions. The Escherichia coli YtfE purified ...
