Aging and calorie restriction modulate yeast redox state, oxidized protein removal, and the ubiquitin-proteasome system
(ELSEVIER SCIENCE INC, 2011)
The ubiquitin-proteasome system governs the half-life of most cellular proteins. Calorie restriction (CR) extends the maximum life span of a variety of species and prevents oxidized protein accumulation. We studied the ...
Causal role of oxidative stress in unfolded protein response development in the hyperthyroid state
(Elsevier, 2015)
L-3,3',5-Triiodothyronine (T-3) induced liver oxidative stress underlies significant protein oxidation, which may trigger the unfolded protein response (UPR). Administration of daily doses of 0.1 mg T-3 for three consecutive ...
Free radicals derived from γ-radiolysis of water and AAPH thermolysis mediate oxidative crosslinking of eGFP involving Tyr-Tyr and Tyr-Cys bonds: the fluorescence of the protein is conserved only towards peroxyl radicals
(Elsevier, 2020)
The enhanced green fluorescent protein (eGFP) is one of the most employed variants of fluorescent proteins.
Nonetheless little is known about the oxidative modifications that this protein can undergo in the cellular ...
DPPH and oxygen free radicals as pro-oxidant of biomolecules
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-03)
Numerous investigations exist about the alterations that oxygen free radicals can provoke on biomolecules; these modifications can be
prevented and/or reversed by different antioxidants agents. On the other hand, ...
Superoxide radical and nephrotoxic effect of cadmium exposure
(1999-06-21)
Pollution and industrial practices result in concentrations of metals and other environmental agents that are related to environmental toxicity. Concentrations of metals are widely related to biochemicals values which are ...

Estudo fotoquímico da ação anti-radicalar de compostos polifenólicos empregando espectrofotometria e HPLC-UV
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2010-02-22)
The interest in antioxidants has increased considerably in recent years as molecules that reduce lipid peroxidation may minimize or inhibit the oxidative damage caused to DNA, proteins and carbohydrates. Flavonoids, a group ...
Use of the Oxygen Radical Absorbance Capacity (ORAC) Assay to Predict the Capacity of Mango (Mangifera indica L.) By-Products to Inhibit Meat Protein Oxidation
(Springer New York LLC, 2017)
The potential activity of mango by-products to inhibit the peroxyl radical-mediated oxidation of tryptophan residues (Trp) of myofibrillar proteins (MP) was studied. Extracts of seeds, peels and pulps were studied in terms ...
Pancreas damage and intratracheal NiCl2 administration. Effects of nickel chloride.
(1990-07-01)
Changes in activities of Cu-Zn superoxide dismutase (SOD- E.C.1.15.1.1.) and lactate dehydrogenase (LDH- E.C.1.1.1.27.) and levels of copper, total protein, triglycerides, phospholipids and total lipids were investigated ...
