O contributo da literacia de informação para a pedagogia universitária:um desaf...
Sanches, Tatiana Luena Baptista e, 1975-Tese de doutoramento, Educação (História da Educação), Universidade de Lisboa, Instituto de Educação, 2014 ; O contexto da presente tese é dado a partir de três eixos temáticos de reflexão: as bibliotecas universitárias, a pedagogia universitária e o agir pedagógico das bibliotecas universitárias, desenvolvidos num arco temporal de cariz historicista incidente sobretudo nos séculos XIX e XX. Posteriormente é r...
Environmental and endocrine assessment of sheep welfare in a climate-controlled...
Baptista, F.J.; Marques, R.; Castro, J.A.; Shahidian, S.; Fitas da Cruz, V.; Sales-Baptista, E.The nutritional status of sheep grazing in the Montado ecosystem varies considerably throughout the year, due to variations in the availability and quality of pastures, strongly influenced by the typical climatic conditions of the Mediterranean region: dry summer and autumn with very little rain. These variations lead to severely restricted feeding for approximately half the year, causing under-nutrition, limit...
Assessing foraging strategies of herbivores in Mediterranean oak woodlands: a r...
Ferraz de Oliveira, M.I.; Lamy, E.; Bugalho, M.N.; Vaz, M; Pinheiro, C; Abreu, M.C.; Capela e Silva, F.; Sales-Baptista, E.Montados are agro-silvo-pastoral ecosystems, typical of the Southwest Iberian Peninsula, of high socio-economic and conservation importance,where grazing is a dominant activity. Montados are characterized by na open tree canopy of Quercus sp. and a diverse undercover of shrubs and grasslands that constitute the plant food resources for grazing animals. Plant food resources of Montados are highly variable, both ...
Financial constraints an application to portuguese firms
Silva, Filipe Manuel Fernandes Rosa Baptista eThis thesis addresses the financing problems faced by firms. Specifically, we test for the existence of firms’ financial constraints, as well as we analyse their role upon firm behaviour. We argue that: a) Portuguese firms face significant financial constraints; b) the extent to which firms are affected by constraints depends on a number of distinct characteristics, beyond financial aspects; c) financial constr...
Effect of condensed tannin ingestion in sheep and goat parotid saliva proteome
Lamy, E; da Costa, G; Santos, R; Capela e Silva, F; Potes, J; Pereira, A; Coelho, AV; Sales Baptista, ESaliva appears as a defence mechanism, against potential negative effects of tannins, in some species of animals which have to deal with these plant secondary metabolites in their regular diets. This study was carried out to investigate changes in parotid saliva protein profiles of sheep Ovis aries)and goats (Capra hircus), induced by condensed tannin ingestion. Five Merino sheep and five Serpentina goats were ...
Morphological alterations in salivary glands of mice (Mus musculus) submitted t...
Lamy,E.; Baptista,E.S.; Coelho,A.V.; Silva,F. Capela eIn order to study the effects of tannins at histomorphological level, mice were either fed with three structurally different types of tannins (tannic acid, chestnut, and quebracho) or treated with isoproterenol, during 10 days. Acini of parotid and submandibular glands increased significantly, being the increase higher for parotid compared to submandibular glands, and higher in the quebracho compared with the o...
Variation in salivary protein composition related to feeding behavior and its e...
Baptista, E; Lamy, E; Mau, M; Capela e Silva, F; Coelho, AVAs feeding strategies are typical traits reflecting the adaptation of species, studies on the ingestive physiology of the different trophic groups could increase the knowledge on the complex dynamic processes of grazing ecosystems. This article points out the potential of salivary protein profiles for non-invasively and dynamically accessing mammal feeding behaviour. The oral cavity is the part of an animal’s i...

Lamy, E; Baptista, E; Coelho, AV; Capela e Silva, FEstudaram-se as alterações morfológicas das glândulas salivares, induzidas por taninos, em camundongos. Os animais foram distribuídos em grupos e tratados com três diferentes tipos estruturais de taninos (ácido tânico, chestnut e quebracho – adicionados à ração) ou isoproterenol via intraperitoneal, durante 10 dias. Os ácinos das glândulas parótida e submandibulares aumentaram significativamente de tamanho, sen...
Changes in mice whole saliva soluble proteome induced by tannin-enriched diets.
Lamy, E; Graça, G; da Costa, G; Franco, C; Capela e Silva, F; Baptista, E; Coelho, AVBackground Previous studies suggested that dietary tannin ingestion may induce changes in mouse salivary proteins in addition to the primarily studied proline-rich proteins (PRPs). The aim of the present study was to determine the protein expression changes induced by condensed tannin intake on the fraction of mouse whole salivary proteins that are unable to form insoluble tannin-protein complexes. Two-dimensi...
Utilização da proteómica para compreender o comportamento de ingestão
Lamy, E.; Capela e Silva, Fernando; Sales Baptista, E.; Graça, G.; da Costa, G.; Coelho, A.V.O comportamento ingestivo é regulado, entre outros, por factores afectivos, os quais determinam diferentes preferências. A escolha da dieta depende de experiências anteriores, bem como do nível de percepção gustativa, estando a saliva envolvida neste último. As proteínas salivares desempenham papéis muito diversos que incluem a lubrificação, digestão, protecção contra microorganismos e factores antinutritivos, ...
