25. Nitric oxide induced alleviation of toxic effects of short term and long term Cd stress on growth, oxidative metabolism and Cd accumulation in Chickpea
The present study investigates the effect of long and short term Cd stress in chickpea plants and evaluates the protective effect of exogenous nitric oxide (NO) supplementation using sodium nitroprusside (SNP). Cadmium treatments were given before sowing (long term stress) and thirty days after germination (short term stress). Sodium nitroprusside was given

26. Corn and soybean meal metabolizable energy with the addition of exogenous enzymes for poultry
Two metabolism assays were carried out to determine corn and soybean meal metabolizable energy when enzymes were added. In the first trial, 35 cockerels per studied feedstuff (corn and soybean meal) were distributed in a completely randomized experimental design with four treatments of seven replicates of one bird each. The evaluated treatments were: ingredi

27. Identificação e expressão de genes da biossíntese do jasmonato na interação entre Theobroma cacao e Moniliophthora perniciosa / Identification and expression of genes associated with jasmonate biosynthesis in the Theobroma cacao and Moniliophthora perniciosa interaction
Witches broom disease of cacao (Theobroma cacao L.), caused by the basidiomycete Moniliophthora perniciosa is an important disease and the use of resistant varieties is the only economic and environmental long-term solution. Plant hormones are essential in the signaling network involved in the response against a variety of biotic and abiotic stresses. It is

28. Effect of iNOS pharmacologic inhibitors in the insulin signalization and sensitivity in obese animal / Efeito de inibidores farmacologicos da iNOS na sensibilidade e sinalização de insulina em animais obesos
Nitric oxide synthase (NOS) has been divided into two major sub-enzymes, inducible NOS (iNOS) and constitutive NOS (cNOS). Although nitric oxide (NO) is an important defense mediator, the excessive production of NO has been involved in the pathology of many inflammatory and metabolic diseases. Some studies demonstrate that exogenous nitric oxide (NO) and the

29. Utilização de complexo enzimático em rações contendo farelo de gérmen de milho desengordurado para suínos em crescimento e terminação
Corn grain for its percentage of carbohydrates and energy potential is an excellent source of nutrients for animals, but as the soybean, has a great instability in prices. Therefore, it is clear the need for searching for new alternatives that can economically replace these ingredients. Among many substitutes, there is the defatted corn germ meal (DCGM), wic

30. Performance, energy increment and digestibility of nutrients in broiler chickens diets containing exogenous enzymes / Desempenho, incremento de energia e digestibilidade de nutrientes em rações de frangos de corte contendo enzimas exógenas
Essa pesquisa avaliou o efeito da suplementação de dois complexos enzimáticos sobre o desempenho, incremento de energia e digestibilidade da matéria seca (MS), proteína (PB), aminoácidos (AAs) e extrato etéreo (EE) por 3 metodologias (coleta total de fezes, coleta com indicador e coleta ileal) em rações de frangos. No ensaio de desempenho foram util

31. Conexão entre os processos de degradação das reservas de proteinas e carboidratos e o edfeito dos hormonios e açucares em sementes de Sesbania virgata (Cav.) Pers / Connection between storage proteins and carbohydrates degradation and the effects of hormones and sugars in seeds of Sesbania virgata (Cav.) Pers
Seeds of Sesbania virgata (Cav.) Pers. have an endosperm which accumulates galactomannan as a storage polysaccharide in the cell walls that is hydrolysed after germination by three enzymes (a-galactosidase, endo-ß-mannanase and exo-ß-mannosidase). Besides the storage of carbon, there is a great amount of protein bodies in the cytoplasm of endospermic cells

32. Indicadores Biológicos de Exposição a solventes orgânicos e sua inter-relação com o estresse oxidativo / Biological Exposure Indices of organic solvents and its relationship with the oxidative stress
The use of organic solvents in the work environment represents a significant risk to workers health. The painters composed, among others, a group of individuals who are in direct contact with solvents through the respiratory and dermal route. The biological monitoring, through biological exposure index (BEI) determination, can ensure the emergence of chronic

33. Pharmacological characterization of ASP49 PLA2 isolated from Bothrops pauloensis venom / Caracterização farmacologica de uma fosfolipase A2 ASP49 isolada do veneno de Bothrops pauloensis
Bothropic venom has several substances necessary to serpent survival, among them, one of the most widely studied are phospholipase A2 enzymes, that hydrolise sn-2 from membrane phospholipids, releasing lysophospholipids and fatty acids, which beyond playing a biological action in the lipid digestion process, also exhibit a wide variety of pharmacological eff

34. Termorregulação colonial e energética individual em abelhas sem ferrão Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae, Meliponini) / Colonial thermoregulation and energetics in stingless bees Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae, Meliponini).
In eusocial insects, such as stingless bees, the control of nest conditions and maintenance of the colonial microclimate are important to brood incubation, development of eggs, larvae and pupae, and survival of the colony. One of the main thermoregulatory mechanisms to control nest temperature is the microhabitat selection to build the nest, such as tree hol

35. Antioxidantes na manutenção do equilíbrio redox cutâneo: uso e avaliação de sua eficácia
The skin is a very complex organ, continuously exposed to physical, chemical and microbiological agents. Enzymes as well as low-molecular weight antioxidants are present in the cutaneous tissue to counterbalance the deleterious effect caused by an oxidative stress and thus maintain homeostasis. Antioxidants such as vitamins C and E, carotenoids, and extracts

36. Caracterização da atividade tríptica do copépodo harpacticoida Tisbe biminiensis.
Tisbe biminiensis is a potential live prey for many species of aquatic animals since its nutritional value is better than those found in other feed organisms commonly used in crustacean and fish larvivultures. Live food seems to be a source of exogenous enzymes which eases food digestion of fish and crustacean early life stages. The aim of this work was to s
