Objective: This study was designed to examine the potential protective effects of Rheum ribes L., and quercetin on protein carbonyl (PCO) in kidney liver tissue, trace elements (Fe, Cu, Zn) mineral (P) serum samples Wistar rats carbon tetrachloride (CCl4)-induced oxidative damage. 
 Methods: The 2, 4-dinitrophenylhydrazine (DNPH) method is most reliable widely used measure levels proteins....

This study evaluated the effects of the interaction of diabetes and a carbonyl iron supplemented on hepatic and pancreatic tissues, oxidative stress markers and liver peroxisome proliferator-activated receptor-α expressions. Hamsters were divided: Control which received a standard AIN 93 diet; Control Iron, composed of control animals that received a diet with 0.83% carbonyl iron; Diabetic, com...

BACKGROUND Renal accumulation of reactive carbonyl compounds (RCCs) has been linked to the progression of diabetic nephropathy. We previously demonstrated that carbonyl stress induces the formation of amino-carbonyl cross-links and sharply increases the content of β-sheet-rich structures, which is the seed of insoluble aggregates formation, and tea catechin (-)-epigallocatechin 3-gallate (EGCG)...

Elevated oxidative stress can alter the function of proteins through the reversible oxidation of the thiol groups of key cysteine residues. This study evaluated a method to scan for reversible protein thiol oxidation in tissue by measuring reduced and oxidized protein thiols. It assessed the responsiveness of protein thiols to oxidative stress in vivo using a dystrophic (mdx) mouse model and co...

Pacu ( Piaractus mesopotamicus ) is one of the most important fish farmed species in Brazil due to its hardy, fast growing, omnivorous feeding behavior, and good consumers acceptance. However, studies on effect different slaughtering procedures quality frozen pacu fillets have not been carried out. Therefore, this study aimed evaluate electrical stunning, CO 2 narcosis, or water/ice immersion (...

The chromophore of fluorescent proteins, including the green fluorescent protein (GFP), contains a highly conjugated imidazolidinone ring. In many fluorescent proteins, the carbonyl group of the imidazolidinone ring engages in a hydrogen bond with the side chain of an arginine residue. Prior studies have indicated that such an electrophilic carbonyl group in a protein often accepts electron den...

Most used in physiotherapy physical factors has an electromagnetic nature. Initially, the therapeutic effect of electromagnetic radiation in a wide range of frequencies associated with activation of metabolic processes in the exposed tissues. The most highly-absorbing ultra high frequency (UHF) energy of tissues are the blood, lymph, parenchymatous tissue, muscles. One of the most important fac...

The purpose of this study was to test the hypothesis that elevation in protein oxidative damage during the aging process is a targeted rather than a stochastic phenomenon. Oxidative damage to proteins in mitochondrial membranes in the flight muscles of the housefly, manifested as carbonyl modifications, was detected immunochemically with anti-dinitrophenyl antibodies. Adenine nucleotide translo...
