1. Avaliação do potencial erosivo do suco de laranja modificado pela adição de caseína e ovalbumina / Evaluation of the erosive potential of an orange juice modified by the addition of casein and ovalbumin [dissertation
The erosive potential of a modified orange juice by addition of casein, ovalbumin and its combination, on human enamel and root dentin was evaluated in this in vitro study. Two dietary proteins, 0.2 g/l casein (CAS), 2.0 g/l ovalbumin (OVA) and their combination (CAS + OVA) were added to a commercially available orange juice. The juice with no additives was

2. Estudos funcionais e estruturais das septinas humanas 6, 8 e 10 / Functional and structural studies of human septin 6, 8 and 10
A cell passes through some steps to enable for cell division and all these processes are called Cell Cycle. The spatial and temporal regulation of this process is crucial to maintaining cellular and genetic material. Failure in this process can lead to cell death or genetic changes causing division and unregulated growth of tumors. Among several proteins inv

3. Glutamine, glutamic acid and or yeast extract in the diet of weaned pigs / Glutamina, ácido glutâmico e ou extrato de levedura na dieta de leitoes desmamados
The present study aimed to evaluate the effects of the supplementation of different sources of protein concentrates, glutamine, acid glutamic and or yeast extract in diets of piglets from 26 to 44 days of age. At 22nd day of age, weaning day, 210 piglets, females and castrated males, crossbred of Landrace, Large White and Duroc races, with 6,79 kg average we

4. INFLUENCE OF A PHYTOGENIC ADDITIVE ON THE BLOOD LEVELS OF HEIFERS JERSEY / INFLUÊNCIA DE UM ADITIVO FITOGÊNICO NOS NÍVEIS SANGÜÍNEOS DE NOVILHAS JERSEY
The experiment was carried out at Itaboapaba Farm, in Silveira Martins RS, Brazil, and was conducted from March 1 up to June 30, 2006, taking 122 days. This study was composed by 20 heifers Jersey race, with average weight of 199 kg and average age of 12 months. The heifers were divided randomly into two treatments: (1) control, in which the basic diet was s

5. An aqueous extract of Pfaffia sp. does not alter the labeling of blood constituents with technetium-99m and the morphology of the red blood cells
Plants have been used for the human beings as food, as additives and/or as medicines. There are controversies about the biological effects of several natural products and, it is worthwhile to try to develop experimental assays to evaluate properties of extracts of plants. Pfaffia sp. is utilized in popular medicine and various properties have been attributed

6. Produção e caracterização de aromas de frutas por microrganismos pectinoliticos utilizando-se residuos agroindustriais. / Production and characterization of fruits flavor for pectinolytic microorganisms using agro-industrial residues.
Pectinases were some of the first enzymes used in commercial applications of wines and fruit juices since 1930 and their use has increased considerably, specially in food, brewery and wine, textile, pulp and paper industries. Today, these enzymes account for approximately 20% of the world enzyme market. Plants, fungi, yeasts, and bacteria naturally produce t

7. Otimização por planejamento experimental da imobilização de lipase em silica de porosidade controlada na presença de estabilizantes
A metodologia de preparação do biocatalisador pode influenciar no processo catalítico. De acordo com estudos anteriores a lipase de Candida rugosa pode ser imobilizada com presença de alta atividade em sílica de porosidade controlada (SPC) ativada com glutaraldeído. Neste trabalho, foram desenvolvidas estratégias para otimizar a estabilidade operacion

8. Effect of Soy Proteins on the Growth of Clostridium perfringens1
Proteins that are used to fabricate imitation foods such as synthetic meats were evaluated for stimulative or inhibitory effects on the growth of Clostridium perfringens. Growth rate and extent were measured in thioglycolate medium without dextrose. This liquid medium contains Trypticase (BBL) which served as the protein control. For comparison, various soy

9. Strategies for the recovery of active proteins through refolding of bacterial inclusion body proteins
Recent advances in generating active proteins through refolding of bacterial inclusion body proteins are summarized in conjunction with a short overview on inclusion body isolation and solubilization procedures. In particular, the pros and cons of well-established robust refolding techniques such as direct dilution as well as less common ones such as diafilt

10. Roles of bovine serum albumin and copper in the assay and stability of ammonia monooxygenase activity in vitro.
We investigated the effects of bovine serum albumin (BSA) on both the assay and the stability of ammonia-oxidizing activity in cell extracts of Nitrosomonas europaea. Ammonia-dependent O2 uptake activity of freshly prepared extracts did not require BSA. However, a dependence on BSA developed in extracts within a short time. The role of BSA in the assay of am

11. Cosecretion of Chaperones and Low-Molecular-Size Medium Additives Increases the Yield of Recombinant Disulfide-Bridged Proteins
Attempts were made to engineer the periplasm of Escherichia coli to an expression compartment of heterologous proteins in their native conformation. As a first approach the low-molecular-size additive l-arginine and the redox compound glutathione (GSH) were added to the culture medium. Addition of 0.4 M l-arginine and 5 mM reduced GSH increased the yield of

12. Effect of Protein Additives on Acetylene Reduction (Nitrogen Fixation) by Rhizobium in the Presence and Absence of Soybean Cells 1
The effect of protein additives on acetylene reduction (N2 fixation) by Rhizobium associated with soybean cells (Glycine max [L.] Merr.) in vitro was studied. Acetylene reduction was promoted on the basal medium supplemented with 1.4 mg of N/ml supplied as aqueous extracts of hexane-extracted soybean, red kidney beans (Phaseolus vulgaris L.), or peas (Pisum
