Use of ß-glucanases and ß-1,4-xylanases to supplement diets containing alfalfa ...
Mourão, J.L.; Ponte, P.I.P; Prates, J.A.M.; Centeno, M.S.J.; Ferreira, L.M.A.; Chaveiro-Soares, M.A.; Fontes, C.M.G.It is well established that the use of alfalfa in diets for monogastric animals is limited by its high fiber content. However, alfalfa is a natural source of xanthophylls and gives poultry products a desirably yellow color. In addition, alfalfa saponins may contribute to reduce the levels of cholesterol in the meat and egg yolk. We have investigated the potential utilization of β-glucanases and β-1,4-xylanases ...
Sentinel node biopsy in breast cancer: results in a large series
Carvalho,S.M.T.; Mourão Netto,M.; Lima,E.N.P.; Pimentel,A.M.; Makdissi,F.B.; Osório,C.A.B.T.; Maciel,M.S.; Iyeyasu,H.; Collins,J.B.; Fontes,C.M.Sentinel lymph node biopsy (SLNB) is an appropriate method for the evaluation of axillary status in cases of early breast cancer. We report our experience in treating cases evaluated using SLNB. We analyzed a total of 1192 cases assessed by means of SLNB from July 1999 to December 2007. SLNB processing was successfully completed in 1154 cases with the use of blue dye or radiolabeled 99mTc-Dextran-500, or both. ...
A PRND polymorphism in Churra do Campo portuguese sheep breed
Mesquita, P.; Silva, M.F.S.; Carolino, M.C.; Sousa, M.C.O.; Pimenta, J.; Marques, M.R.; Santos, I.C.; Gama, L.T.; Andrade, C.S.C.R.; Fontes, C.M.Prion-like Doppel gene (PRND) is located downstream from priori protein gene (PRNP). Doppel protein is not related to prion disease but to male fertility. Our previous analysis of PRND coding region in 460 animals from 8 Portuguese sheep breeds, by multiple restriction fragment-single strand conformation polymorphism (MRFSSCP), revealed a synonymous substitution (78G>A). An association was found between identif...
Improving the lipid nutritive value of poultry meat through the incorporation o...
Ponte, Patricia; Prates, J.A.M; Crespo, J.P.; Crespo, D.G.; Mourão, José Luís,; Alves, S.P; Bessa, J.B.; Chaveiro-Soares, M.A.; Ferreira, L.M.A.Dehydrated forages are assumed to be good sources of α-linolenic acid (ALA) and lipid-soluble antioxidant compounds (vitamin E homologs and β-carotene). The effects of including a dehydrated leguminous-based forage in a typical diet for broiler chicken, on performance, meat quality, and fatty acid composition were evaluated. One hundred sixty 1-d-old male commercial broiler chicks (Ross 308) were housed in 20 b...
Role of a family 11 carbohydrate-binding module in the function of a recombinan...
Lordelo, M.M.; Guerreiro, C.I.P.D.; Ribeiro, T.; Ponte, P.I.P.; Falcão, L.; Freire, J.P.B.; Ferreira, L.M.A.; Prates, J.A.M.; Fontes, C.M.G.A.Cellulases and xylanases display a modular architecture that comprises a catalytic module linked to one or more non-catalytic carbohydrate-binding modules (CBMs). CBMs have been classified into 52 different families, based on primary structure similarity. These non-catalytic modules mediate a prolonged and intimate contact of the enzyme with the target substrate eliciting efficient hydrolysis of the target poly...
A family 11 carbohydrate binding module (CBM) improves the efficacy of a recomb...
Lordelo, M.M.; Ribeiro, T.; Ponte, P.I.P.; Guerreiro, C.I.P.D.; Santos, H.M.; Falcão, L.; Freire, J.P.B.; Ferreira, L.M.A.; Prates, J.A.M.1. Exogenous microbial -1,3-1,4-glucanases and hemicellulases contribute to improving the nutritive value of cereals rich in soluble non-starch polysaccharides for poultry. 2. In general, plant cell wall hydrolases display a modular structure comprising a catalytic module linked to one or more non-catalytic carbohydrate-binding modules (CBMs). Based on primary structure similarity, CBMs have been classified in...
Produção de frangos de carne em pastagens à base de Leguminosas
Ponte, P.I.P; Rosado, C.M.C; Crespo, J.P; Crespo, D.G; Chaveiro-Soares, M.A; Mourão, J.L; Mendes, I; Gama, L.T; Prates, J.A.M; Ferreira, L.M.APortugal apresenta reconhecidas potencialidades edafoclimáticas para a produção de pastagens à base de leguminosas, tanto em condições de regadio como de sequeiro. Este trabalho pretendeu avaliar a possibilidade de desenvolver formas alternativas para a produção de frangos de carne em pastagens. Avaliou-se o desempenho produtivo de frangos RedBro Cou Nu x RedBro M mantidos dos 28 aos 56 dias em pastagens de se...
