Care: new challenges arising from transnational dynamics

Guerra, Inês; Barros, Carlos

Care and support are central determinants of social work. However, the needs and specificities for an integral perception of this assistance need to be drawn in the context of a globalizing society and increasingly evident macro and micro contextual phenomena. By taking care of aging people in the context of Portuguese transnational families as an example, this paper aims to be a space of dialogue between chall...


Impact of seasons on industrial cultivation of Limnospira platensis (Spirulina)...

Guerra, Inês; Torres, Cátia; Cardoso, Helena; Pereira, Hugo; Trovão, Mafalda; Rodrigues, Alexandre M. C.; Varela, João

Spirulina is the most commercially produced biomass, among microalgae and cyanobacteria, with extensive applications across food, feed, nutraceutical and biotechnological sectors. While Spirulina cultivation is wellcharacterized at laboratorial and small-scale production, critical knowledge gaps remain regarding industrialscale production in temperate climates. Specifically, there is a lack of robust empirical ...


Heterotrophic and Photoautotrophic Media Optimization Using Response Surface Me...

Correia, Nádia; Pereira, Hugo; Schulze, Peter; Costa, Monya M.; Santo, Gonçalo E.; Guerra, Inês; Trovão, Mafalda; Barros, Ana; Cardoso, Helena

ABSTRACT: The nutritional requirements of novel microalgal strains are key for their effective cultivation and metabolite content. Therefore, the optimization of heterotrophic and photoautotrophic culture media is crucial for novel Chlorococcum amblystomatis growth. Heterotrophic and photoautotrophic biomass samples were characterized to identify the differences between their heterotrophic and photoautotrophic ...

Evaluation of the fertilizer potential of Chlorella vulgaris and Scenedesmus ob...

Alvarenga, Paula; Martins, Marta; Ribeiro, Henrique; Mota, Mariana; Guerra, Inês; Cardoso, Helena; Silva, Joana Laranjeira

Producing microalgae with agricultural drainage water (ADW) allows recycling water and nutrients, with the production of a biofertilizer, avoiding receiving waters' contamination. Chlorella vulgaris and Scenedesmus obliquus were cultivated using ADW and standard media supplementation and presented higher productivities, relatively to the control industrial growth medium (using freshwater). Selected strains were...

The nutritional requirements of novel microalgal strains are key for their effective cultivation and metabolite content. Therefore, the optimization of heterotrophic and photoautotrophic culture media is crucial for novel Chlorococcum amblystomatis growth. Heterotrophic and photoautotrophic biomass samples were characterized to identify the differences between their heterotrophic and photoautotrophic biomass co...


In vitro antagonism evaluation of endophyte Chaetomium aureum against Cryphonec...

Coelho, Valentim; Machado, Júlia Melo; Guerra, Inês; Gouveia, Maria Eugénia

The European chestnut tree (Castanea sativa Mill.) is threatened by various microfungi that affect its production. In the trunk and branches infected by chestnut blight (Cryphonectria parasitica (Murril) Barr.) it was observed the presence of several microfungi that co-occur in the presence of the disease among which the endophytic fungus Chaetomium aureum Chivers. Many species of the genus Chaetomium are descr...

Prevalence of the Most Frequent Neuropsychiatric Diagnoses in Hospitalized SARS...

Fernandes, Luis Afonso; Garcia Ribeiro, Catarina; Martins, Marisa; Figueiredo, Inês; Dias, Manuel; Facucho, João; Carreno, Joana; Guerra, Inês

Introduction: The SARS-CoV-2 infection has been associated with the acute onset of mental and behavioural symptoms and psychiatric disorders. The aim of this study was to assess the prevalence of the different neuropsychiatric diagnoses in hospitalized patients with SARS-CoV-2 infection assessed by Liaison Psychiatry.Material and Methods: We performed a cross-sectional study in a hospital near Lisbon, Portugal....

Effects of outdoor and indoor cultivation on the polar lipid composition and an...

Couto, Daniela; Conde, Tiago A.; Melo, Tânia; Neves, Bruna; Costa, Margarida; Cunha, Pedro; Guerra, Inês; Correia, Nádia; Silva, Joana T.; Pereira, Hugo

Nannochloropsis is a genus of eicosapentaenoic acid-rich microalgae with high levels of value-added polar lipids. However, the polar lipid composition of microalgal biomass is highly dependent on culture conditions (e.g., light or temperature), which are significantly different under indoor and outdoor culture conditions. In this study, we sought to investigate the plasticity of the polar lipid profile of a mar...


Future perspectives of microalgae in the food industry

Ferreira, Alice; Guerra, Inês; Costa, Margarida; Silva, Joana; Gouveia, Luisa

ABSTRACT: Microalgae have been consumed by humans for thousands of years. Research has shown that microalgae exhibit huge potential to meet the dietary needs of the growing population, generating great interest in these organisms. Thanks to their nutritional composition, mainly their high protein content, but also to the presence of bioactive compounds with functional properties that provide added health benefi...

Operation regimes: A comparison based on Nannochloropsis oceanica biomass and l...

Guerra, Inês; Pereira, Hugo; Costa, Margarida; Silva, Joana T.; Santos, Tamara; Varela, João; Mateus, Marília; Silva, Joana

Microalgae are currently considered to be a promising feedstock for biodiesel production. However, significant research efforts are crucial to improve the current biomass and lipid productivities under real outdoor production conditions. In this context, batch, continuous and semi-continuous operation regimes were compared during the Spring/Summer seasons in 2.6 m(3) tubular photobioreactors to select the most ...
