- The immunome and embryo quality in sea bream and sea bassPublication . Li, Lisen; Power, Deborah; Guerreiro, Liliana I.T. dos AnjosGilthead sea bream (Sparus aurata) and European sea bass (Dicentrarchus labrax) are teleosts belonging to Eupercaria and are the most important aquaculture fish species in the Mediterranean region. These two species are ranked second after the Atlantic salmon (Salmo salar) in production volume and value in the European Union (EU) aquaculture sector. Unpredictable fertilized egg/embryo quality and performance remain a bottleneck that threatens sustainability of sea bream and sea bass aquaculture, impeding the increased productivity of aquaculture that entirely depends on hatchery production. To address this issue, criteria and molecular markers linked to embryo quality that could be used to monitor and manage hatchery production were procured. Comparative molecular approaches using molecular biology, proteomics and transcriptomics were performed to analyze embryo performance and immunity in samples from several European commercial hatcheries. The core achievements were the: a) identification and characterization of lysozyme and complement 5 (C5) gene families and embryo and larval gene expression and enzyme activity from a diversity of hatcheries, b) characterization of the embryo proteome from three Mediterranean fish species [white sea bream (Diplodus sargus), meagre (Argyrosomus regius) and sea bream] 24h before hatch and at hatch and identification of common and species specific molecular patterns linked to biological function and putative quality-related proteins, c) comparative transcriptomics of good and poor quality sea bream embryos from several Mediterranean hatcheries. Qualitylinked transcripts and some elements of the regulatory epitranscriptome (non-coding RNA) were identified as well as the contribution of maternal proteins to embryos. Taken together, the results provide a comprehensive description of the molecular basis of sea bream and sea bass embryo development and reveal that immune-related molecules in fertilized eggs are low abundance. The development (quality)-related candidate markers identified will be of value for management of fish embryos in aquaculture hatcheries.
- Anteprojeto de arquitetura paisagista para o jardim terapêutico do departamento de psiquiatria e saúde mental do Centro Hospitalar do Algarve: princípios de desenho de jardins terapêuticos destinados a doentes mentaisPublication . Costa, Catarina Alexandra Luís; Silva, Ana Paula Gomes; Fernandes, JacintaEsta dissertação, na modalidade projeto, tem como objetivo o desenvolvimento de uma proposta de jardim terapêutico ao nível do projeto de anteprojeto para o Departamento de Psiquiatria do Centro Hospitalar Universitário do Algarve (DPCHUA), localizado na ci-dade de Faro. Atualmente o espaço exterior do hospital encontra-se pouco cuidado e sem capacidade de oferecer benefícios terapêuticos aos seus utilizadores. Com esta requalifi-cação pretende-se uma humanização do hospital, amplificação do potencial terapêutico das instalações e o aumento da satisfação e bem-estar, especialmente dos utentes, mas também dos profissionais de saúde e visitantes. Para apoiar e enriquecer a proposta, apre-senta-se uma revisão bibliográfica sobre jardins em ambiente hospitalar. Os benefícios terapêuticos do contacto com a natureza são conhecidos desde tempos mui-tos antigos, embora o conceito de jardim terapêutico e o estudo dos seus benefícios, fo-cados no paciente, sejam relativamente recentes. São descritos alguns dos princípios ge-rais de desenho de jardins terapêuticos, bem como princípios específicos para doenças mentais. Foram realizadas visitas ao espaço exterior do DPCHUA para levantamento e diagnóstico da situação existente, e efetuadas reuniões com variados técnicos de saúde do Centro Hospitalar, para recolha de informação sobre as suas perceções das necessidades e expec-tativas e relativamente a este espaço exterior. Resultado da aplicação dos princípios de desenho de jardins terapêuticos destinados a doentes mentais, ajustada à realidade do espaço existente e às necessidades e expectativas percebidas dos utentes, foi desenvolvida uma proposta de intervenção para o DPCHUA, incluindo as peças técnicas de anteprojeto. Espera-se que em estudos futuros seja realizada uma lista das espécies vegetativas de valor para esta tipologia de jardim, um levantamento dos jardins terapêuticos existentes em território nacional, bem como as respetivas análises pré e pós ocupação, que são tão importantes na estruturação de princípios de desenho para esta tipologia de espaços.
- Tourism impacts in Badagry Town: a case study from Lagos (Nigeria)Publication . Badmus, Olaronke Oluwaseun; Pinto, HugoTourism is a major source of growth for developing and developed countries, driven by a strong global economy, an increasing middle class, technological advance, and affordable travel. Prepandemic figures show that international tourist arrivals reached 1.4 billion, and export earnings from tourism reached USD 1.7 trillion in 2019. Europe has traditionally been the region with the highest tourism dollar spending with 570 billion USD, followed by Asia and the Pacific (USD 435 billion), the Americas (USD 334 billion), the Middle East (USD 73 billion), and Africa (USD 38 billion). Asia has shown the strongest growth in both arrivals (+7%) and spending (+7%). Africa equally shared a +7% growth in arrivals, suggesting a new interest in traveling to the continent. The study aimed at investigating the impacts of tourism in Badagry Town, Lagos (Nigeria). The study was qualitative in nature and used a case study approach, which offers an in-depth assessment of the topic. The study employed a reflexive literature review and also a content analysis inspired by systematic literature review principles to analyze the data gathered from this review. Badagry is well known for its tourism potential. The literature review identified several sites of interest for tourism development, such as: the Badagry slave trade relics, Sultan Beach, Whispering Palms, French Village Badagry, Seat of the British Canon, Vekete Slave Market, Seat of the Fallen Agia Tree, Early Missionary Cemetery in Nigeria, First Storey Building in Nigeria, Mobee Slave Relics Museum, Slave Port, Slave "Point of No Return," and Badagry Heritage Museum. This dissertation also explored not only the economic and environmental impacts of tourism but also the social impacts, as they are clearly connected to some of the key tourism resources identified in this town. Social impacts are particularly attentive to the learning potential of tourism from different cultures, increasing tolerance and inclusion, increasing amenities, investment in arts and culture, celebration of indigenous people, and community pride. The study concluded that increased attention to tourism facilities may boost tourism in Badagry. Georeferenced information, such as interactive map apps, can help tourists identify tourist sites and their specific locations. Tourism in Badagry should be supported by residents, entrepreneurs, and other stakeholders to ensure long-term sustainability and economic growth. The promotion of cross-cultural appreciation and its influence on the flow of cultural interchange are important, but overtourism can lead to an increase in demand for resources and negative social impacts. Tourism development should be rewarding for residents, employees, and tourists.
