13. In silico molecular modeling and docking studies on the leishmanial tryparedoxin peroxidase
Leishmaniasis is one of the most common form of neglected parasitic disease that affects about 350 million people worldwide. Leishmanias have a trypanothione mediated hydroperoxide metabolism to eliminate endogenous or exogenous oxidative agents. Both of 2-Cys peroxiredoxin (Prx) and glutathione peroxidase type tryparedoxin peroxidase (Px) are the terminal e

14. Efeitos da adição de complexo multienzimático sobre o desempenho de frangos de corte / Effects of adding multienzyme complex on the performance of broilers
Two experiments were conducted at the Department of Animal Science, University of São Paulo (USP), College of Animal Science and Food Engineering (FZEA) in Pirassununga / SP, with the aim of studying the performance of broilers fed diets supplemented with exogenous enzymes. The experimental diets consisted of corn, soybean meal, vitamins, minerals and exoge

15. Desempenho de bovinos alimentados com dietas contendo enzimas amilolíticas exógenas / Performance of cattle feed with diets containing amylolytic enzymes exogenous
O uso de ionóforos como promotores de crescimento em bovinos de corte está sendo colocado como barreira pelos países da União Européia para a exportação de carne bovina. Diante desse desafio, novos produtos estão sendo pesquisados para incrementar o desempenho animal, dentre os quais aqueles contendo atividade enzimática. O presente trabalho teve co

16. Apparent digestibility of simplified and semi-simplified diets, with and without addition of enzymes, and nutritional value of fibrous sources for rabbits
The objectives of this study were to evaluate the digestibility of the nutrients of simplified and semi-simplified diets, with and without inclusion of exogenous enzymes and to determine the nutritional value of the fibrous sources. The tested feedstuffs were: alfalfa hay, hay from the upper third of the cassava foliage and cassava leaf meal, using a complet

17. The level of ascorbate peroxidase is enhanced in benznidazole-resistant populations of Trypanosoma cruzi and its expression is modulated by stress generated by hydrogen peroxide
Ascorbate peroxidases (APX) are class I heme-containing enzymes that convert hydrogen peroxide into water molecules. The gene encoding APX has been characterized in 11 strains of Trypanosoma cruzi that are sensitive or resistant to benznidazole (BZ). Bioinformatic analysis revealed the presence of two complete copies of the T. cruzi APX (TcAPX) gene in the g

18. Análise do transcritôma e proteôma do colmo de cana-de-açúcar relacionada ao metabolismo da sacarose / Transcriptomic and proteomic analysis of sugarcane culm relationaded to sucrose metabolism
Sugarcane is a important crop in the Brazilian economy for both, sugar and green biofuel production, accounting for more than US$ 20 billions/year, placing Brazil as the most important country in this trade. On the other hand sugarcane has reached a limit in sucrose production, an effect of the narrow gene pool used in current commercial breeding programs. O

19. Exogenous enzymes in pre-starter broiler diets based on corn and soybean meal
A fibrolytic enzyme complex was added to the pre-starter diet. Broiler chicks were randomly distributed into five treatments, consisting of a diet with no enzyme addition and four test diets supplemented with 100, 200, 300 and 400g/T of an enzyme complex. The dietary inclusion of the enzyme complex increased weight gain, and the dose of 300g/T improved weigh

20. Transgenic plants of Petunia hybrida harboring the CYP2E1 gene efficiently remove benzene and toluene pollutants and improve resistance to formaldehyde
The CYP2E1 protein belongs to the P450 enzymes family and plays an important role in the metabolism of small molecular and organic pollutants. In this study we generated CYP2E1 transgenic plants of Petunia using Agrobacterium rhizogenes K599. PCR analysis confirmed that the regenerated plants contained the CYP2E1 transgene and the rolB gene of the Ri plasmid

21. Changes in growth, pigment content and antioxidants in the root and leaf tissues of wheat plants under the influence of exogenous salicylic acid
The effect of various concentrations of salicylic acid (SA) on the growth, pigment content and the activity of antioxidants was investigated in the laboratory grown wheat plants. The root and shoot growth was affected at higher concentration of SA in early days of growth. The activities of catalase (CAT), ascorbate peroxidase (APX) and guaicol-specific perox

24. Ameliorative effect of exogenous nitric oxide on oxidative metabolism in NaCl treated chickpea plants
Accumulation of salts in irrigated soils is one of the primary factors limiting yield in South Asia. We investigated whether exogenous nitric oxide (NO) supplementation as sodium nitroprusside has any ameliorating effect against NaCl induced oxidative damage in chickpea leaves. NaCl treatment (250 mM) alone and in combination with two concentrations of SNP (
