1. Enzymatic Properties and Ryegrass Resistance Mechanism to Iodosulfuron-Methyl-Sodium Herbicide
RESUMO: O azevém (Lolium multiflorum) é uma das espécies mais preocupantes em relação à resistência aos herbicidas. Este estudo objetivou caracterizar a atividade da enzima acetolactato sintase (ALS) de biótipos resistentes (NC e AR) e suscetível de azevém ao herbicida iodosulfurom-metílico sódio (iodosulfurom). Diferentes concentrações de piru

2. Ethyl-pyruvate reduces lung injury matrix metalloproteinases and cytokines and improves survival in experimental model of severe acute pancreatitis
PURPOSE: To investigate if the ethyl-pyruvate solution could reduce mortality in AP and/or diminish the acute lung injury. METHODS: Forty male rats, weighing between 270 to 330 grams were operated. An experimental model of severe AP by injection of 0.1ml/100g of 2.5% sodium taurocholate into the bilio-pancreatic duct was utilized. The rats were divided into

3. Effect of exposure to sublethal concentrations of sodium cyanide on the carbohydrate metabolism of the Indian Major Carp Labeo rohita (Hamilton, 1822)
Experiments were designed to study in-vivo effects of sodium cyanide on biochemical endpoints in the freshwater fish Labeo rohita. Fish were exposed to two sublethal concentrations (0.106 and 0.064mg/L) for a period of 15 days. Levels of glycogen, pyruvate, lactate and the enzymatic activities of lactate dehydrogenase (LDH), succinate dehydrogenase (SDH), gl

4. Efeitos do etil-piruvato no tratamento da resposta inflamatória da lesão pulmonar na pancreatite aguda necrosante induzida em ratos. / Effects of ethyl-pyruvate in the inflammatory response of lung injury in experimental acute pancreatitis in rats.
INTRODUCTION: Severe acute pancreatitis (AP) is characterized by hemodynamic alterations and systemic inflammatory response leading to a high mortality rate. In AP the inappropriate activation of pancreatic enzymes plays an important role in pancreas autodigestion and in the inflammatory mechanisms responsible for the systemic response of the disease.

5. Efeito da adição de antioxidantes na qualidade do sêmen criopreservado de bovino / Effect of antioxidants on quality of bovine semen cryopreserved
Os antioxidantes têm como função neutralizar os efeitos dos radicais livres proporcionando uma melhor qualidade do sêmen fresco e criopreservado. O objetivo deste trabalho foi estudar o efeito da adição dos antioxidantes catalase, α-tocoferol e piruvato de sódio no sêmen bovino visando um controle das espécies reativas de oxigênio para melhora

6. Application of response surface methodology to enhancement of biomass production by Lactobacillus rhamnosus E/N
Response surface methodology (RSM) was employed to study the effects of various medium components on biomass production by Lactobacillus rhamnosus E/N. This strain is commonly used in the pharmaceutical and food industries due to its beneficial effect on the human gut and general health. The best medium composition derived from RSM regression was (in g/l) gl

7. Atividade antioxidante e hepatoprotetora de plantas brasileiras, contendo compostos fenólicos.
Plants from Brazilian flora were chosen and studied for their in vitro and in vivo antioxidant and in vivo hepatoprotetive activity, especially in relation to phenolic compounds which have several health benefits. These plants include Phyllanthus niruri, Solanum fastigiatum, Solidago microglossa and Baccharis trimera. The aqueous extracts of leaves showed in

8. Análise da atividade linfoproliferativa de células esplênicas murinas frente a extrato de seis plantas medicinais da flora catarinense / Analysis of the citotoxic and lymphoproliferative activity of methanolic exctracts of medicinal plants on murine spleen cells
Some compounds have been used as immunomodulatory agents, enabling the function of the immune system to be modified, stimulating or suppressing it. There has been increasing interest in the study of therapeutic activities of plant extracts in recent years, including their immunomodulatory activity. The aim of the present work is to identify and evaluate the

9. Maturation of pig oocytes in vitro in a medium with pyruvate
The aim of in vitro maturation oocyte systems is to produce oocytes of comparable quality to those derived in vivo. The present study was designed to examine the surface morphological changes of the cumulus-oocyte complex (COC) and nuclear maturation in a culture system containing pyruvate. Ovaries were obtained from a slaughterhouseand transported to the la

10. Efeitos da L-arginina sobre as concentraÃÃes de metabÃlitos in vivo no sangue e em cicatriz de retalho miocutÃneo, e sobre a pressÃo de rotura de cicatriz cirÃrgica intestinal em ratos / Effects of L-arginine upon the concentration of metabolites, in vivo, in the blood, miocutaneous skin graft scar and on the pressure of rupture of intestinal surgical scar in rats
Cicatrization, contraction and deposition of connective tissue matrix constitute healing mechanisms for the development of the wound scar. Studies have demonstrated that L-arginine favors cicatrization, increasing the synthesis of collagen. The aim of this paper was to study the effects of L-arginine upon the concentrations of glucose, pyruvate, lactate and

11. Inactivation of clostridial ferredoxin and pyruvate-ferredoxin oxidoreductase by sodium nitrite.
Clostridial ferredoxin and pyruvate-ferredoxin oxidoreductase activity was investigated after in vitro or in vivo treatment with sodium nitrite. In vitro treatment of commercially available Clostridium pasteurianum ferredoxin with sodium nitrite inhibited ferredoxin activity. Inhibition of ferredoxin activity increased with increasing levels of sodium nitrit

12. Fermentative metabolism of pyruvate by Rhodospirillum rubrum after anaerobic growth in darkness.
Rhodospirillum rubrum grew anaerobically in darkness and fermented sodium pyruvate by a pyruvate formate-lyase reaction. During 30 min of anaerobic dark or light incubation with sodium pyrivate, crude extracts from fermentatively grown cells produced about 6 micronmol of acetylphosphate and formate per mg of protein in reactions performed at pH 8.3.
