Microalgae extracts reduce appetite in zebrafish larvae linked to long-chain fa...

Appetite modulation is a promising strategy for obesity treatment. The presented research screened 103 microalgae extracts from three strains of microalgae (Chlorella sp., Chlorococcum sp. and Nannochloropsis oceanica) for appetite reducing activity, using high pressure processing and moderate electric fields. Two different feeding assays with zebrafish larvae were applied using either fluorescent labeled lipos...

Use of Chlorella vulgaris lipidic extracts in the development of healthier past...

Pastry products constitute a significant segment of the food market. However, the high amount of fat used in their production poses a challenge when competing for the attention of modern consumers, who are more conscious of the health problems associated with the consumption of high-fat products. With this in mind, the main objective of this study is the reduction of the total fat and saturated fat contents of ...

Nonthermal high-pressure microalgae extracts: A new source of natural ingredien...

Microalgae are one of the most prominent sources of ingredients for the cosmetic industry not only due to their diversity but, importantly, due to the low environmental impact in production and extraction. A sustainable extraction process requires the use of effective and environmentally friendly solvents that guarantee an extract with a relevant content and in high yields. In this work, Chlorella vulgaris, Nan...

Construções contrastivas com “mas”, Contraste Sintagmático e Elipse do TP

No português, mas ocorre em duas construções estruturalmente distintas, Contraste Sintagmático, envolvendo tipicamente contraste entre sintagmas não frásicos, e Elipse do TP com itens de polaridade, contrastando duas frases, uma delas elíptica. Em línguas como o espanhol e o alemão, a coordenação contrastiva faz apelo a duas conjunções diferentes, tipicamente associadas a duas construções com valor distinto, o ...

Frases imperativas e negação em Português Europeu

Em línguas como o Espanhol, o Italiano e o Português Europeu, formas verbais morfologicamente específicas alternam com formas verbais supletivas para expressar o imperativo. Contudo, o seu comportamento difere relativamente à negação frásica: os imperativos verdadeiros rejeitam a presença de negação frásica em oposição aos imperativos supletivos. Este contraste foi atribuído a causas diversas: a diferenças de c...

Paratactic that-connective structures in non-argumental clauses

In European and Brazilian Portuguese gramatical tradition, non-argumental clauses introduced by que ‘that’ have been classified as causal explicative clauses. However, differently from the other explicative conetives, que may head non-argumental clauses displaying other meanings, such as result/consequence or simultaneous temporal readings. We take these different readings as resulting from the context, and we ...

Relativas livres e interrogativas parciais: como Óscar Lopes viu algumas destas...

Neste artigo analisamos alguns aspetos sintáticos e semânticos das relativas livres e das interrogativas subordinadas parciais próprias e impróprias, desenvolvendo Brito (1991), Brito & Duarte (2003), Móia (1996), Veloso (2013), Matos & Brito (2013), Mioto & Lobo (2016), correlacionando-os com a forma como Óscar Lopes descreveu estas construções e destacando a ambiguidade estrutural e semântica de algumas delas...

Reduced Parenthetical Clauses and the syntax-discourse interface

Reduced parenthetical clauses (RPCs) in European Portuguese have not been systematically studied until recently. Focusing on comment RPCs, a preliminary classification of the most common verbal predicates in this context is set up for this language, and their pragmatic values established. The distribution of comment RPCs, especially their floating status and the blocking of c-command from the host sentences, in...

Specificities of coordinative “nem” in European Portuguese

European Portuguese nem corresponds to two different categories, a coordenative conjunction and a negative non-conjunctional element that in some contexts assumes a scalar meaning. We will show that, although both of these homonymous particles necessarily occur in negative domains, they have a different syntactic distribution and display specific properties. Focusing on coordenative nem in correlative and the n...
