Proposing biomarkers to evaluate the alterations in the brain iron homeostasis and their relation with the physiopathology of Alzheimer's disease Proponiendo biomarcadores para evaluar las alteraciones en la homeostasis cerebral de hierro y su relación co
(2007)
Multiple lines of evidence have implicated oxidative stress and free radical damage to the pathogenesis and etiology of Alzheimer's disease (AD). Amyloid-beta peptide contributes to oxidative damage in AD by inducing lipid ...
High Levels of Iron Status and Oxidative Stress in Patients with Metabolic Syndrome
(Springer, 2013)
Studies concerning oxidative stress (OxE) parameters
have increased, mainly because of its important role in
cardiovascular diseases and diabetes complications. The
main objective of this study was to evaluate iron ...
Insights into the iron and sulfur energetic metabolism of Acidithiobacillus ferrooxidans by microarray transcriptome profiling
(ELSEVIER, 2006-09)
Acidithiobacillus ferrooxidans is a well known acidophilic, chemolithoautotrophic, Gram negative, bacterium involved in bioleaching and acid mine drainage. In aerobic conditions, it gains energy mainly from the oxidation ...
Alteraciones del metabolismo del fierro post bypass gástrico
(Hospital Clínico Universidad de Chile, 2010)
A complication of bariatric surgery and especially gastric bypass are nutritional deficiencies that occur in the long term, being very important iron deficiency and anemia. Several mechanisms influence this, highlighting ...
Regulation of transepithelial transport of iron by hepcidin
(2006)
Hepcidin (Hepc) is a 25 amino acid cationic peptide with broad antibacterial and antifungal actions. A likely
role for Hepc in iron metabolism was suggested by the observation that mice having disruption of the gene
encoding ...
Regulation of transepithelial transport of iron by hepcidin
(SOCIEDAD BIOLGIA CHILE, 2005-05-24)
Hepcidin (Hepc) is a 25 amino acid cationic peptide with broad antibacterial and antifungal actions. A likely
role for Hepc in iron metabolism was suggested by the observation that mice having disruption of the gene
encoding ...
Stoichiometric Model and Flux Balance Analysis for a Mixed Culture of Leptospirillum ferriphilum and Ferroplasma acidiphilum
(Wiley-Blackwell, 2015)
The oxidation process of sulfide minerals in natural environments is achieved by microbial
communities from the Archaea and Bacteria domains. A metabolic reconstruction of two
dominant species, Leptospirillum ferriphilum ...
Iron, anemia, and infection
(1997)
The data on the relationship between iron deficiency and infection are conflicting. Some researchers conclude that mild iron deficiency is beneficial for immunity, whereas others contend that any deficit is not good for ...
Antioxidant responses of cortex neurons to iron loading
(2006)
Brain cells have a highly active oxidative metabolism, yet they contain only low to moderate superoxide dismutase and catalase activities. Thus, their antioxidant defenses rely mainly on cellular reduced glutathione
levels. ...
MiR-155 and miR-122 expression of spermatozoa in obese subjects
(Frontiers Media S.A., 2018-05-29)
Obesity is characterized by mild chronic inflammation that is linked with impaired iron homeostasis. Studies in human and murine show that there is a transgenerational epigenetic inheritance via the gametes in obesity; ...
