1. Effect of feeding grape seed Proanthocyanidin extract on production performance, metabolic and anti-oxidative status of dairy cattle
RESUMO O presente trabalho visa investigar os efeitos do extrato de semente de uva Proanthocyanidin (GSPE) sobre o desempenho da produção, o metabolismo e o status antioxidante de gado leiteiro Holstein em lactação precoce. Quarenta e oito vacas leiteiras multíparas Holstein foram divididas em quatro grupos (CON, G20, G40 e G80) e receberam 0, 20, 40 e

2. The Effect of Thyme Essential Oil (Thymus Vulgaris) Added to Quail Diets on Performance, Some Blood Parameters, and the Antioxidative Metabolism of the Serum and Liver Tissues
ABSTRACT This study was conducted to determine the effect of diets containing different levels of thyme essential oil (TEO) on performance, some serum parameters and the antioxidative metabolism of the serum and liver tissues in quails. A total number of 200 sixteen-days-old Japanese quails (Coturnix coturnix japonica) were used in the study. The animals wer

3. Differential expression on mitochondrial tryparedoxin peroxidase (mTcTXNPx) in Trypanosoma cruzi after ferrocenyl diamine hydrochlorides treatments
Abstract Resistance to benznidazole in certain strains of Trypanosoma cruzi may be caused by the increased production of enzymes that act on the oxidative metabolism, such as mitochondrial tryparedoxin peroxidase which catalyses the reduction of peroxides. This work presents cytotoxicity assays performed with ferrocenyl diamine hydrochlorides in six differen

4. Photosynthetic gas exchange and antioxidative system in common bean plants infected by Colletotrichum lindemuthianum and supplied with silicon
This study investigated the effects of silicon (Si) on the resistance of common bean plants to anthracnose caused by Colletotrichum lindemuthianum. The plants were grown in a nutrient solution containing 0 (control) or 2 mM Si (+Si) and both photosynthesis and antioxidative metabolism levels were evaluated. The Si concentrations in the leaf tissues of +Si pl

5. Arsênio em plantas aquáticas: absorção, toxicidade, nutrição e metabolismo da glutationa / Arsenic in aquatic plants: absorption, toxicity, nutrition and glutathione metabolism
Arsenic (As) toxicity and its effects on glutathione metabolism were analyzed in two vegetal specimens: Lemna gibba and Salvinia minima. Plants were cultivated in nutrient solution, pH 6.5, and exposed to arsenic concentrations of 0.0 and 1.0 mg L-1, for three days. Both species accumulated As in their tissues when exposed to this element, being this accumul

6. Influence of chromium salts on increased lipid peroxidation and differential pattern in antioxidant metabolism in Pistia stratiotes L
In this work, the changing effect of different concentrations (0, 0.01, 0.1, 1, 10mM) of hexavalent and trivalent chromium on different biochemical parameters along with antioxidant enzymes was investigated on water lettuce (Pistia stratiotes L.) in order to know the possible involvement of this metal in oxidative injury, besides the activities of antioxidan

7. Estudo da resposta antioxidativa de linhagens bacterianas na presença do herbicida Acetochlor / Study of the response antioxidative of bacterial strains in the presence of herbicide Acetochlor
Currently there is a great concern with respect to short and long term effects that many herbicides may cause on public health and the environment. They may seriously damage the cellular metabolism, generally leading to inhibition of the microbial growth. With the exposure to herbicides, these microorganisms significantly increase the generation of EAOs (Act

8. Evaluation of the oxidative metabolism and kidney and liver histopathology in copper intoxicated lambs treated with tetrathiomolybdate and/or antioxidative vitamins / Avaliação do metabolismo oxidativo e da histopatologia renal e hepática de ovinos intoxicados por cobre e tratados com tetratiomolibdato e vitaminas antioxidantes
The efficiency of intra muscular vitamin C (VC) and/or E (VE) associated with the classical copper chelate tetrathiomolybdate (TTM) in cumulative copper poisoning treatment was evaluated. Twenty six Santa Inês male lambs weighting 25 kg were distributed in four treatment groups (TTM; TTM+VC; TTM+VE; TTM+VCE). The oxidative metabolism was analyzed through me

9. Expression profile of oxidative and antioxidative stress enzymes based on ESTs approach of citrus
Plants not only evolve but also reduce oxygen in photosynthesis. An inevitable consequence of this normal process is the production of reactive oxygen species (ROS). Plants are adequately protected by the presence of multiple antioxidative enzymes in the cytosol and also in the different cell organelles such as chloroplasts, mitochondria, and peroxisomes. Tr

10. Antioxidative responses of water hyacinth under cadmium stress / Resposta antioxidativa de aguapé sob estresse por cádmio
Plants of hyancinth were treated during 8 days in water containing 0,05 and 0,50 mM of CdCl2 under natural light in a glasshouse maintained at 25-32°C with a 16 h photoperiod. The effect of cadmium on oxidative enzymes and nitrogen metabolism was studied. After 8 days an alteration on SOD activity was observed when the pattern of bands was analyzed by e

11. Trocas gasosas e metabolismo antioxidativo em Coffea canephora em resposta ao sombreamento promovido por Hevea brasiliensis / Gas exchange and antioxidative metabolism in Coffea canephora in response to shading from Hevea brasiliensis
Apesar de ter evoluído em ambientes sombreados, o café conilon (Coffea canephora) vem sendo cultivado tradicionalmente a pleno sol. Atualmente, há um interesse crescente em cultivar-se o café em sistemas arborizados e, portanto, sob algum grau de sombreamento. Neste trabalho, procurou-se contrastar dois clones de café conilon, o 109A (relativamente sens

12. Atividade respiratória e metabolismo antioxidativo em raízes de plântulas de milho (Zea mays L.) submetidas ao estresse salino / Respiration activity and antioxidative metabolism in roots of maize (Zea mays L.) seedlings submitted to salt stress
Tolerance to salt stress was studied in maize seedlings (Zea mays L.) cultivars AGN 3150, BR 106, BR 201, BR 206 and SHS 4040, grown in Hoaglands nutrient solution. Treatments with NaCl 50 and 100 mM led to a decrease in the biomass production and to an increase in the relative electrolyte leakage in the roots and shoots in all cultivars. However, the larges
