25. Cooking effect and inhibition of angiotensin I converting enzyme and alpha-amylase by compound phenolics from brown rice / Efeito do cozimento e ação dos compostos fenólicos de arroz integral na inibição da enzima conversora de angiotensina I e da alfa-amilase
Rice (Oryza sativa L.) sustains at present about half of the world´s population. Consumption is mainly in its milled form, but brown rice has prompted further research due to bioactive compounds present in the pericarp of the grain. Some of the positive health effects have been attributed to radical scavenging activity and other biological effects such as i

26. Funcionalidade dos extratos fenólicos obtidos pelo cultivo semi-sólido de resíduos de abacaxi (Ananas comusus L.) e goiaba (Psidium guajava L.)
Solid substrate cultivation (SSC) has become an efficient alternative towards rational use of agro industrial wastes and production of value-added products, mainly in developing countries. This work presents the production and functional application results of phenolic extracts obtained by solid substrate cultivation of pineapple (Ananas comosus L.) and guav

27. Efeito da espermina na qualidade fisiológica de sementes de alface / Effect of spermine on the physiological quality of seeds of lettuce
The objective of this study was to investigate the performance of growth regulators: Gibberellic acid, spermine and abscisic acid on germination and early growth of seedlings of lettuce cv. Grand Rapids. For this, experiments were conducted in greenhouse and laboratory. The seeds were treated with test solutions of gibberellic acid at a concentration of 0.5m

28. Enzimas de organismos aquÃticos e suas aplicaÃÃes fisiolÃgicas
In the last years, there has been a general increase in human demand for fishery products, followed by a significant increase in the world production of aquatic organisms. The growth of fishery industry generates, as consequence, large amounts of wastes and by-products rich in biomolecules, which are discharged into envioronment. Fishery wastes can be used i

29. Ação inibitória de extratos de plantas do Cerrado sobre α-amilases com ênfase em Kielmeyera coriacea
α-amylases are digestive enzymes widely distributed in microrganims, plants and animals, that catalyze hidrolysis of α-1,4 glicosidic bonds and act in carbohydrate metabolism. The inhibition of α-amylases can be applied on control of insect pests that depends on starch-rich diet to energy production, reducing the amount of nutrients to avoid i

30. Estudo comparativo entre faseolamina comercial e farinha de feijÃo como perspectiva ao tratamento da obesidade e do diabetes mellitus tipo 2. / Comparative study between commercial phaseolamine and bean flour as a perspective to the treatment of obesity and type 2 diabetes mellitus.
Use of plants of medicinal purposes represents a wide field of research. New therapeutic proposals need studies to evaluate the appropriate use as to posology, indication, limitations and risks of utilization. The search for new phytotherapeutic ones as an alternative to the traditional medicinal treatment of obesity and of the type 2 diabetes mellitus has b

31. Produção de uma fração concentrada em alfa-amilase salivar humana (HSA) como alvo para descoberta de novos inibidores e fracionamento do extrato hidroalcóolico da casca de Pouteria sp
Capítulo II: As alfa-amilases (α-1,4-D-glicano-4-glicanohidrolases, EC 3.2.1.1) são enzimas responsáveis pela digestão de carboidratos e são encontradas na saliva e no suco pancreático. As seqüências primárias das alfa-amilases salivar (HSA) e pancreática (HPA) exibem 99% de similaridade estrutural o que sugere que a HSA pode ser um alvo de es

32. Bicho-mineiro do cafeeiro: anÃlise da digestÃo e inibiÃÃo de tripsina por extratos de folhas de mamona. / Coffee leaf miner: Digestion and trypsin inhibition using castor beam leaves extracts.
Coffee is a crop of great social and economic importance to Brazil and its production is affected by a number of pests and diseases. One of those pests is the coffee leaf miner, Leucoptera coffeella (GuÃrin-MÃneville, 1842) (Lepidoptera: Lyonetiidae) which can cause great losses in production. The forms of controlling the coffee leaf miner known and utiliz

33. Screening for carbohydrate-binding proteins in extracts of Uruguayan plants
The presence of carbohydrate-binding proteins, namely lectins, ß-galactosidases and amylases, was determined in aqueous extracts of plants collected in Uruguay. Twenty-six extracts were prepared from 15 Uruguayan plants belonging to 12 Phanerogam families. Among them, 18 extracts caused hemagglutination (HAG) that was inhibited by mono- and disaccharides in

34. Effects of alpha-amylase on in vitro growth of Legionella pneumophila.
Sterile parotid saliva inhibited growth of Legionella pneumophila on solid media, and the salivary component involved in this inhibition has been shown to be amylase. Disk diffusion and well plate assays were used to study possible mechanisms for this effect. The amylolytic activity of saliva copurified with inhibitory activity, and both activities were sens

35. Inhibition of Gibberellic Acid-induced α-Amylase Formation by Polyethylene Glycol and Mannitol 1
Both polyethylene glycol (PEG) and mannitol inhibit gibberellic acid-induced α-amylase production in barley aleurone layers. The effect of the osmotic solution is on enzyme synthesis rather than α-amylase secretion. The inhibition of α-amylase synthesis does not appear to be mediated via an indirect effect on respiration or protein synthesis. Rather it se

36. Lead inhibition of enzyme synthesis in soil.
Addition of 2 mg of Pb2+/g of soil concident with or after amendment with starch or maltose resulted in 75 and 50% decreases in net synthesis of amylase and alpha-glucosidase, respectively. Invertase synthesis in sucrose-amended soil was transiently reduced after Pb2+ addition. Amylase activity was several times less sensitive to Pb2+ inhibition than was enz
