Real-time single-cell imaging reveals accelerating lipid peroxyl radical formation in Escherichia coli triggered by a fluoroquinolone antibiotic
(American Chemical Society, 2020-07)
Formation of reactive oxygen species (ROS) induced by bactericidal antibiotics has been associated with a common, non-specific, mechanism of cellular death. Herein we report real-time single cell fluorescence studies on ...
Antioxidant activity of gadusol and occurrence in fish roes from Argentine Sea
(Elsevier, 2010-03-15)
The occurrence of the natural antioxidant gadusol (3,5,6-trihydroxy-5-hydroxymethyl-2-methoxycyclohex-2-en-1-one) was quantified in fish roes of three species from Argentine Sea: argentine hake (Merluccius hubbsi), brazilian ...
Tyrosine oxidation and nitration in transmembrane peptides is connected to lipid peroxidation
(Elsevier Science Inc, 2017-05)
Tyrosine nitration is an oxidative post-translational modification that can occur in proteins associated to hydrophobic bio-structures such as membranes and lipoproteins. In this work, we have studied tyrosine nitration ...
Free radical scavenging capacity and antioxidant activity of cochineal (Dactylopius coccus C.) extracts
(Elsevier, 2010-03)
Carminic acid (CA) is a natural red pigment produced by Dactylopius coccus C. insects. It is widely used in the food industry to replace synthetic colourants. Despite being known for a long time, its antioxidant properties ...
Free radical scavenging activities and inhibition of inflammatory enzymes of phenolics isolated from Tripodanthus acutifolius
(Elsevier Ireland, 2010-07)
Ethnopharmacological relevance: Leaf extracts from Tripodanthus acutifolius (Ruiz and Pavón) Van Tieghem have long been used in argentinean traditional medicine as anti-inflammatory, however, there is no scientific evidence ...
Protein-lipid interactions modulate lipid composition, membrane dynamics and structure
(Nova Science Publishers, 2018)
The interactions of proteins with membrane surfaces are important to many biological processes, including signaling, recognition, and membrane trafficking, cell division and cell structure. When the Fluid Mosaic Model (FMM) ...
Regulation of lipid peroxidation and ferroptosis in diverse species
(Cold Spring Harbor Laboratory Press, 2018-05)
Lipid peroxidation is the process by which oxygen combines with lipids to generate lipid hydroperoxides via intermediate formation of peroxyl radicals. Vitamin E and coenzyme Q10 react with peroxyl radicals to yield ...
Biological activities of Zn(II)- S -methyl-cysteine complex as antiradical, inhibitor of acid phosphatase enzyme and in vivo antidepressant effects
(Taylor & Francis, 2016-03)
The antidepressant effect of simple Zn(II) salts has been proved in several animal models of depression. In this study, a coordination metal complex of Zn(II) having a sulfur containing ligand is tested as antidepressant ...
Reactive Oxygen Species
(Studium Press, 2011)
Molecular oxygen (O2) is essential for the survival of all aerobic organisms, because it acts as the final acceptor of mitochondrial electron chain. In this situation, O2 is reduced to H2O after the cytochrome-c oxidase ...
Antioxidant and anticancer effects and bioavailability studies of the flavonoid baicalin and its oxidovanadium(IV) complex
(Elsevier Science Inc, 2017-01)
Based on the known antioxidant effect of flavonoids, baicalin (baic) found in roots of Scutellaria has been selected. Its coordination complex with the oxidovanadium(IV) cation, Na4[VO(baic)2].6H2O (VIVO(baic)), was ...
