The role of temporary accommodation buildings for post-disaster housing reconstruction
The number of houses damaged or destroyed after disasters is frequently large, and re-housing of homeless people is one of the most important tasks of reconstruction programmes. Reconstruction works often last long and during that time, it is essential to provide victims with the minimum conditions to live with dignity, privacy, and protection. This research intends to demonstrate the crucial role of temporary accommodation buildings to provide spaces where people can live and gradually resume their life until they have a permanent house. The study also aims to identify the main problems of temporary accommodation strategies and to discuss some principles and guidelines in order to reach better design solutions. It is found that temporary accommodation is an issue that goes beyond the simple provision of buildings, since the whole space for temporary settlement is important. Likewise, temporary accommodation is a process that should start before a disaster occurs, as a preventive pre-planning. In spite of being temporary constructions, these housing buildings are one of the most important elements to provide in emergency scenarios, contributing for better recovery and reconstruction actions.The first author gratefully acknowledges the financial support of Fundacao para a Ciencia e a Tecnologia, FCT, through grant SFRH/BD/73853/2010

Secretome of mesenchymal stem cells and its impact on Chronic Obstructive Pulmonary Disease
Chronic obstructive pulmonary disease (COPD) is characterized by irreversible loss of lung function that stem from two mechanisms, inflammation and senescence. Crosstalk between these two mechanisms accelerate the development of COPD, thus targeting these two pathways may offer benefits in the treatment of COPD. Growing amount of evidence have shown that mesenchymal stem cells as a promising candidate for the treatment of COPD. Over the years, many studies conducted to decipher the therapeutic effect of MSC in COPD and the mechanisms involve, in the hope of utilizing these cells as new therapeutic strategy for COPD. However, the cell-based therapy by using the MSC presented with many obstacles including low engraftment at the site of injury, the risk of microvascular occlusion, unwanted differentiation, and also the risk of malignant transformation. Recently, recently researchers begin to look at the possibility of using MSC derived extracellular vesicles as an alternative to MSC. Here we review the effect of MSC and MSC derived EV in modulating inflammation, and senescence in COPD. We also review current treatment and the side effect in COPD, and senolytic drugs, a new therapeutic strategy targeting the senescent cells
