The World Health Organization (WHO) recognizes that health and well-being are essential to achieving the United Nations (UN) Development Agenda 2030, which includes the goal of empowering people to adopt active lifestyles while protecting the planet's health. This article aims at exploring how exercise performed in different natural settings can contribute to improving health and to a more sustainable world. We define "exercise" as a form of physical activity undertaken to increase fitness, health, and well-being, and argue for the importance of "green" and "blue" exercise as forms of physical activity that are associated with the protection and sustainability of natural settings and the promotion of planetary health. Blue and green exercise should become a focus of public policies, especially when outdoor activities are being identified as fundamental for the promotion of mental, physical, social, and spiritual health. The current paper intends to raise the awareness of political decision-makers and professionals in education, environment, and heath sectors for the potential of green and blue exercise as specific exercise practices that are healthy, joyful, and environmentally friendly.

With this article we aim to propose an analytical alternative to what we could call the substitution and condemnation of the spectator as an element of the new technological apparatuses. Actually, what we see in many of the current reflections on new media is that while the spectator is being accused of ultimate passivity, he is also being mobilized to emancipated action as an empowered user. Through the critique of an online application available on RTP's website, the state-owned television network, called O Meu Telejornal, we will try to demonstrate that we actually need to develop a spectator theory to critically understand the political position of the citizen within our changing contemporary media environment. ; Fundação para a Ciência e a Tecnologia ...

Vascular grafts are used to bypass damaged or diseased blood vessels. Bacterial cellulose (BC) has been studied for use as an off-the-shelf graft. Herein, we present a novel, cost-effective, method for the production of small caliber BC grafts with minimal processing or requirements. The morphology of the graft wall produced a tensile strength above that of native vessels, performing similarly to the current commercial alternatives. As a result of the production method, the luminal surface of the graft presents similar topography to that of native vessels. We have also studied the in vivo behavior of these BC graft in order to further demonstrate their viability. In these preliminary studies, 1 month patency was achieved, with the presence of neo-vessels and endothelial cells on the luminal surface of the graft. ; This study was supported by the Portuguese Foundation for Science and Technology (FCT) and the European Community fund FEDER, through Program COMPETE, under the scope of the Projects FCOMP-01-0124-FEDER-007025 (PTDC/AMB/68393/2006), PEST-OE/EQB/LA0023/2013, PEST-C/FIS/UI607/2013, RECI/BBB-EBI/0179/2012 (FCOMP-01-0124-FEDER-027462) and the Projects "BioEnv-Biotechnology and Bioengineering for a sustainable world" and "Matepro-Optimizing Materials and Processes".
