Identification of novel GAPDH-derived antimicrobial peptides secreted by Saccha...
Branco, Patrícia; Francisco, Diana; Chambon, Christophe; Hébraud, Michel; Arneborg, Nils; Almeida, Maria G.; Caldeira, Jorge; Albergaria, HelenaSaccharomyces cerevisiae plays a primordial role in alcoholic fermentation and has a vastworldwide application in the production of fuel-ethanol, food and beverages. The dominance of S. cerevisiae over other microbial species during alcoholic fermentations has been traditionally ascribed to its higher ethanol tolerance. However, recent studies suggested that other phenomena, such as microbial interactions media...
Dominance of Saccharomyces cerevisiae in wine fermentations: secretion of antim...
Albergaria, Helena; Branco, Patrícia; Francisco, Diana; Coutinho, Rute; Monteiro, Margarida; Malfeito-Ferreira, M.; Arneborg, Nils; Almeida, Maria G.In present work we investigated the antagonistic effect by S. cerevisiae against several wine-related microbial species vis-à-vis the secretion of antimicrobial peptides (AMPs).
Antimicrobial peptides from Saccharomyces cerevisiae induce physiological chang...
Branco, Patrícia; Albergaria, Helena; Arneborg, NilsSaccharomyces cerevisiae secretes antimicrobial peptides (AMPs) during alcoholic fermentation that are active against other wine-related yeasts (e.g. Hanseniaspora guilliermondii) (Albergaria et al., 2010) and bacteria (e.g. Oenococcus oeni) (Osborne and Edwards, 2007). In the present study we assessed the physiological changes induced by those AMPs on sensitive yeast cells of Hanseniaspora guilliermondii, name...
Saccharomyces cerevisiae and Dekkera bruxellensis interactions in alcoholic fer...
Coutinho, Rute; Branco, Patrícia; Monteiro, Margarida; Malfeito-Ferreira, M.; Albergaria, HelenaThe yeast Dekkera/Brettanomyces bruxellensis can cause enormous economic losses both in wine industry and fuel-ethanol processes due to production of phenolic off-flavour compounds and low ethanol productivities. In winemaking this microbial hazard is usually tackled by the use of chemical preservatives such as sulphur dioxide. In spite of this, D. bruxellensis strains are frequently found in wines at low level...
Interactions between Saccharomyces cerevisiae and Hanseniaspora guilliermondii:...
Branco, Patrícia; Kemsawasd, Varongsiri; Arneborg, Nils; Albergaria, HelenaSeveral studies have shown that the early death of non-Saccharomyces during wine fermentations are due to yeast-yeast interactions induced by Saccharomyces cerevisiae (Sc) through different mechanisms such as growth arrest mediated by a cell-cell contact mechanism (Nissen et al. 2003) and death mediated by killer-like toxins (Pérez-Nevado et al 2006; Albergaria et al. 2010). Besides, previous work also showed t...
Ankle-brachial index, vascular calcifications and mortality in dialysis patients
Adragao, Teresa; Pires, Ana; Branco, Patricia; Castro, Rui; Oliveira, Ana; Nogueira, Cristina; Bordalo, Joaquim; Curto, Jose Dias; Prata, Mateus MartinsWOS:000299957700048 (Nº de Acesso Web of Science) ; “Prémio Científico ISCTE-IUL 2013” ; Background. The ankle-brachial index (ABI) is a noninvasive method to evaluate peripheral artery disease (PAD). ABI <0.9 diagnoses PAD; ABI >1.3 is a false negative caused by noncompressible arteries. The aim of this study is to evaluate the association between ABI with vascular calcifications (VC) and with mortality, in ...
O acesso ao direito e à justiça: Um direito humano à compreensão
Branco, PatríciaFalar de acesso ao direito e à justiça continua a ser fundamental. Talvez hoje mais do que nunca, em que se continua a falar de uma crise na justiça, seja necessário questionar o que é e em que consistirá aceder ao direito e à justiça e que tipos de obstáculos estarão ainda a barrar o acesso dos cidadãos a este seu direito basilar. O primeiro tipo de obstáculos, e que está geralmente contemplado nas normas lega...
The Semiotic Approach to Jurisprudence: Can it make an original contribution? -...
Branco, PatríciaLegal semiotics offers a critical point of view and attempts a new approach to legal theory, based on a different kind of rationality which appeals to the construction of sense through narrative models, thus reaching the conclusion that there is no conceptual difference between law and fact. Hence, it aims to offer a fresh approach to legal theory, especially in what concerns the way of explaining decision-maki...
Valor nutricional de alimentos para suínos determinado na Universidade Federal ...
Santos,Zuleide Alves de Souza; Freitas,Rilke Tadeu Fonseca de; Fialho,Elias Tadeu; Rodrigues,Paulo Borges; Lima,José Augusto de FreitasForam conduzidos seis ensaios de metabolismo no Departamento de Zootecnia da Universidade Federal de Lavras (UFLA) no ano de 2002, com objetivo de avaliar a composição química e nutricional de 8 alimentos protéicos e 10 energéticos. Para o primeiro ensaio, foram selecionados animais de peso-vivo médio de 40,4 kg, sendo analisado o farelo de algodão, soja micronizada, farelo de soja, farelo de linhaça, farinha d...
Evaluation of sunflower meal on growth and carcass traits of finishing pigs
Carellos,Douglas de Carvalho; Lima,José Augusto de Freitas; Fialho,Elias Tadeu; Freitas,Rilke Tadeu Fonseca de; Silva,Hunaldo OliveiraWith the objective to evaluate the influence of increasing levels of inclusion of sunflower meal (SFM) solvent extraction (DM: 92.71%, CP: 27.50%, NDF: 43.57%, ADF: 32.96%, CF: 25.91%, EE: 3,08% and GE: 4390 kcal) on the performance and carcass characteristics of finishing swine, a performance trial was conducted in the Department of Animal Science of the Federal University of Lavras - MG. A total of 80 crossbr...
