13. Adhesion-preventing properties of 4% icodextrin and canola oil: a comparative experimental study
OBJECTIVE: Postsurgical abdominal adhesions are common, serious postoperative complications. The present study compared the usefulness of 4% icodextrin and canola oil in preventing postoperative peritoneal adhesions. METHODS: Twenty-four Wistar albino rats were divided into three groups. Following a laparotomy, a serosal abrasion was made by brushing the cec

14. Optimization of process parameters for cellulase production from Bacillus sp. JS14 in solid substrate fermentation using response surface methodology
The aim of this work was to isolate the potent bacterial strains for the production of cellulose enzyme. A total 30 bacterial isolates showed positive results for the cellulase production but highest enzyme activity was shown by isolate JS 14. From the morphological and biochemical reactions, the isolate was identified as Bacillus sp. Cellulase production wa

15. Disposição de lodo adensado de ETA em ETE com tratamento primário quimicamente assistido / Thickened water treatment sludge disposal in a wastewater treatment presenting a chemically enhanced primary treatment
Treatment systems, even for water potabilization or to reduce the amount of pollutants in wastewater, include physical, chemical and biological processes, and waste generation are inherent to water or sewage treatment plants. Solid waste generated in water treatment plants have inorganic characteristic, being removed from raw water by chemical and physical p

16. Produção, caracterização bioquímica e purificação de fitase produzida por Aspergillus niger var. phoenicis URM 4924.
During ripening, vegetable seeds and grain accumulated substantial amount of phytic acid, representing over 60% of total phosphorus in them. Phytate acts as an energy source for seed germination and is rarely available for non-ruminants, since they do not synthesize the enzyme. Due to the unavailability of biological organic phosphorus in many vegetable food

17. In vitro antimicrobial resistance of Pseudomonas aeruginosa isolated from canine otitis externa in Rio de Janeiro , Brazil
Isolates of Pseudomonas aeruginosa (167) were obtained from 528 samples of canine otitis externa, identified by biochemical reactions and tested for susceptibility to 10 antimicrobials. The most effective drug was ciprofloxacin. The study reports alarming resistance among P. aeruginosa isolated from canine otitis externa samples in Rio de Janeiro, Brazil.

18. Utilização de inteligência artificial (redes neurais artificiais) para a classificação do comportamento bioquímico de amostras de Escherichia coli isoladas de frangos de corte / The use of artificial intelligence (artifical neural networks) to classify the biochemical reactions of Escherichia colli isolates from broilers
A Escherichia coli é comumente encontrada na avicultura e muitas vezes sua presença no organismo dos animais e/ou contaminando as camas de aviários não causa estranheza. Por outro lado, a utilização de inteligência artificial, especificamente redes neurais artificiais, está sendo crescentemente empregada como ferramenta para medir relações não lin

19. Aspectos morfofisiologicos das cultivares de cafeeiro Catuai-Vermelho e Conilon.
O objetivo deste trabalho foi comparar cafeeiros das espécies Coffea arabica L. cv. Catuaí-Vermelho e C. canephora Pierre cv. Conilon quanto à fotossíntese líquida e a aspectos da anatomia foliar a esta relacionados. Verificaram-se taxas fotossintética líquida, transpiratória e de condutância estomática maiores em plantas de C. canephora. As planta

20. Use of response surface methodology to optimization of extraction of enzymes from pineapple pulp.
The enzymatic reactions are very important for food. They are responsíble for the formation of highly desirable cornpound, but can cause disorders and undesirable consequences. The physiological behaviour of vegetables and fruits is already known, so that most of its deterioration changes in flavour, colour and nutritional value are caused by enzymes of the

21. Reversion to virulence evaluation of a 9R vaccine strain of Salmonella enterica serovar gallinarum in commercial brown layers
The live vaccine Cevac S. Gallinarum, made from a rough strain of Salmonella enterica subspecies enterica serotype Gallinarum is used for preventing fowl typhoid, a disease that still causes considerable economic losses in countries with a developing poultry industry. The objective of this paper was to evaluate a possible reversion to virulence of the strain

24. Epidemic aspects of the infection for Leptospira spp in domestic felines (Felis catus) seemingly healthy of the metropolitan area of Goiânia, Goiás / ASPECTOS EPIDEMIOLÓGICOS DA INFECÇÃO POR LEPTOSPIRA SPP. EM FELINOS DOMÉSTICOS (FELIS CATUS) APARENTEMENTE SADIOS DA REGIÃO METROPOLITANA DE GOIÂNIA , GOIÁS
In felines, the leptospirosis is described commonly as of rare occurrence, in spite of inquiries sorologic accomplished at several countries they have already registered positive reactions in these you encourage. In this research it was aimed at to evaluate the presence of antibodies anti-Leptospira spp in samples of serums of domestic felines originating fr
