This is the case of Generation Z, a technological generation that will become the leading group of consumers in the coming years. Despite the positive results regarding this practice, the expected ...

Fotografias do arquivo municipal de Lisboa: Das imagens documentais às narrativ...

A fotografia documental permite a fixação de um determinado tempo e espaço, segundo o olhar do autor, fixando paisagens, comunidades e vivências, registando o palimpsesto (Corboz, 1983) existente, a identidade e a memória coletiva (Halbawachs, 1925) das comunidades que lhes estão associadas, revelando que as paisagens são história pública (Hayden, 1995), que estão em constante mutação e que a imagem pode guarda...

Dinâmicas espaciais nas antigas estradas de acesso a Lisboa: O Largo do Rato e ...

Localizados no centro da cidade de Lisboa, o Campo das Cebolas e o Largo do Rato são dois espaços públicos diferentes, situados em áreas distintas, que pertencem a antigas estradas de acesso ao centro e com as quais partilham a história, a evolução, o traçado e as vivências. Este ensaio pretende sublinhar algumas das especificidades que definem estes espaços e que permanecem visíveis na atualidade, identificand...

Are we aiming for different metabolic targets in heart failure patients?

Introduction: Metabolic control plays an important role on major cardiovascular events (MACE) prevention. The 2019 ESC guidelines on dyslipidaemia management recommend tighter LDL-cholesterol (LDL-C) control in order to prevent cardiovascular events. However, it is not yet proven that thigh control of dyslipidaemia, glycaemic levels and body mass index (BMI) in Heart Failure (HF) patients (pts) have an impact o...

The effect of different drying processes on physicochemical characteristics and...

The main objective of this study was to evaluate the effect of two different drying methods on physicochemical characteristics and antioxidant activity of different Brassica spp. cultivars in order to produce a dietary flour. Fresh cabbages were subjected to two drying methods: convective air-drying (80 °C, during 2h with the previous blanching) and freeze-drying. An increase in crude protein, carbohydrates and...

The influence of fixation temperature in in vitro DNA analysis

Introduction: Formalin-fixed and paraffin-embedded (FFPE) are important sources for molecular studies, namely to identify cancer related biomarkers. Nevertheless, the quality of FFPE-obtained DNA is lower than that of fresh/frozen tissues, since fixation induces several chemical modifications. The impact of tissue fixation duration, fixative type and pH on the integrity of FFPE-extracted DNA has been the subjec...
