| The aim of the present study was to investigate the effects of daily intragastric administration of bullfrog oil (oleic, linoleic and palmitoleic acid-rich oil), corresponding to 0.4% of body weight for four weeks, on fatty acid composition and oxidative stress (lipid peroxidation and catalase activity) in mouse liver. The activities of aspartate aminotransferase (AST), alkaline phosphatase (ALP), alanine aminotransferase (ALT), and gamma-glutamyltransferase (GGT), biomarkers of tissue injury, were determined in liver homogenates and serum. The proportions of 18:2n-6, 20:4n-6, 20:5n-3, and 22:6n-3 (polyunsaturated fatty acids, from 37 to 60%) in the total fatty acid content were increased in the liver of the bullfrog oil-treated group (P < 0.05)... |

| ABSTRACT: This research aimed to evaluate whether the essential oil of Aloysia triphylla (EOAT) used in vivo as a sedative in the water for transporting fish could increase the oxidative stability of silver catfish (Rhamdia quelen) fillets during frozen storage. The chemical composition of EOAT and of fillets from fish exposed to EOAT (0, 30 or 40µL L-1) were assessed. The pH and lipid oxidation parameters (conjugated dienes, CD; thiobarbituric acid-reactive-substances, TBARS) were evaluated in the fillets throughout the storage period (-18±2oC/17 months). The main compounds found in EOAT were α- and β-citral. Treatment with EOAT did not modify the proximate composition of the fillets, but 40µL L-1 EOAT reduced pH levels when compared to the control... |

| Anemia due to worm infection is a major cause of loss in the sheep industry, due to deaths, drop in average daily gains and long recovery time following treatment. The present experiment was aimed at evaluating the oxidative status and the recovery of red blood cell (RBC) profile in lambs with induced anemia by bleeding, treated or not with dextran iron. Ten ram lambs 5 to 7 months old were used. Blood samples were drawn every other day and when reached packed cell volume (PCV) of 15% were randomly allocated (day zero) to one of the experimental groups. Treated group received a single dose of 25mg per kg body weight of a commercial formulation of dextran iron, the control group received no treatment. Blood samples were taken on days 0, 7, 14, and 21 after... |

| Os óleos essenciais são alternativas ao uso de promotores de crescimento antibióticos na avicultura, devido à sua ação antimicrobiana, além de possuírem propriedades antioxidante e imunomoduladora. Este estudo foi realizado com o objetivo de avaliar o efeito da suplementação dietética de três doses de óleos essenciais (OLES) de orégano (Origanum vulgare L.), sálvia (Salvia officinalis L.), alecrim (Rosmarinus officinalis L.) e extrato de pimenta (Capsicum frutescens L.) em frangos de corte, pela análise do perfil eletroforético de soroproteínas e da peroxidação lipídica plasmática. Os animais (n=910) foram alocados de forma aleatória em cinco tratamentos, com sete repetições de 26 aves cada: o grupo controle (Tc), que recebeu dieta basal sem aditivos; o... |

| Paletas suínas desossadas pesando em média 1,6kg receberam injeção de salmoura contendo Staphylococcus xylosus. Permaneceram 30 dias em câmara de maturação em duas faixas de temperatura diferentes (2°C a 8°C e de 4°C a 9°C), sendo posteriormente armazenadas durante 120 dias, nas temperaturas de 10°C e 25°C, embaladas a vácuo. Durante o período de permanência das paletas dentro da câmara e durante o armazenamento, foram monitorados os valores de nitrito e TBARS com o objetivo de identificar onde o nitrito atuaria como conservante e antioxidante e onde o nível de TBARS poderia ser prejudicial à saúde do consumidor. Observou-se que a concentração dos nitritos até o décimo dia de permanência da paleta dentro da câmara, no segundo tratamento, atuou como efeito... |

| Agricultural practices are directly related to the use of pesticides, which indiscriminately and without due care may contribute to the occurrence of numerous intoxications. Several studies have demonstrated the relationship of certain pesticides and the occurrence of oxidative stress and therefore, in recent years have developed methods of analysis of several biomarkers of cellular damage that can be measured and quantified. In this context, the objective of this study was to evaluate the possible changes in biochemical markers: glutamic aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, urea, total protein, and oxidative markers such as lipid peroxidation, damage to proteins and the activity of the enzymes acetylcholinesterase... |
