Technological advances applied to TB vaccine development: how can AI contribute...

Pereira, João Santos; Pires, David

Tuberculosis is a long-standing global health challenge. Yet, so far, all efforts to develop an effective vaccine that surpasses the limitations of the century-old BCG vaccine have been unsuccessful. This calls for new technological solutions that can aid researchers in digesting decades of data and predict the solutions with the highest successful outcomes. This chapter discusses how Artificial Intelligence (A...


GIANT EGIST OF THE TRANSVERSE MESOCOLON: CASE REPORT

Martins Jordão, Daniel Filipe; Martins, Rui; Pereira, João Santos; Ferrão, Henrique; Ferrão, Isabel Cristina

Gastrointestinal stromal tumors are rare tumors of the gastroistestinal tract. Less than 5% of these are not associated to the gastrointestinal tract, being designated EGISTs. EGISTs of the mesocolon are extremely rare, with just a few cases reported in the literature. We present the case of an 82-year old female presenting with nausea and vomiting for a month, having had an ultra-sound(US) and CT which showed ...

Climate control of terrestrial carbon exchange across biomes and continents

Yi, Chuixiang; Li, Runze; Wolbeck, John; Xu, Xiyan; Nilsson, Mats B.; Aires, Luis Miguel Igreja; Albertson, John D.; Ammann, Christoph

Understanding the relationships between climate and carbon exchange by terrestrial ecosystems is critical to predict future levels of atmospheric carbon dioxide because of the potential accelerating effects of positive climate-carbon cycle feedbacks. However, directly observed relationships between climate and terrestrial CO2exchange with the atmosphere across biomes and continents are lacking. Here we present ...

Drought reduces tree growing season lenght but increases nitrogen resorption ef...

Lobo Do Vale, Raquel; Besson, Cathy Kurz; Caldeira, Maria; Chaves, Maria Manuela; Pereira, João Santos

Mediterranean ecosystems are hotspots for climate change, as the highest impacts are forecasted for the Mediterranean region, mainly by more frequent and intense severe droughts. Plant phenology is a good indicator of species’ responses to climate change. In this study, we compared the spring phenology of cork oak trees (Quercus suber), an evergreen species, over 2 contrasting years, a mild year (2004) and a dr...


Geographic variation in cork oak and its implications for expected impacts of c...

Rodrigues, Ana; Sampaio, Teresa; Silva, João Costa e; Patrício, Maria Sameiro; Silva, Filipe Costa e; Faria, Carla Maria Gomes Marques

Cork oak (Quercus suber L.) is a protected tree species in Portugal, being also the source of raw material for the cork industry, a major player in Portuguese economy (representing 3% of GDP in 2010). The future climatic scenarios for Portugal point to an increase in average summer temperatures from 0.3 to 0.7ºC between 2016 and 2035, and up to 4.6ºC until 2100. In addition, precipitation estimates suggest a re...

Estimation of cork production using aerial imagery

Surovy, Peter; Ribeiro, Nuno de Almeida; Pereira, João Santos; Yoshimoto, Atsushi

Inventory and prediction of cork harvest over time and space is important to forest managers who must plan and organize harvest logistics (transport, storage, etc.). Common field inventory methods including the stem density, diameter and height structure are costly and generally point (plot) based. Furthermore, the irregular horizontal structure of cork oak stands makes it difficult, if not impossible, to inter...
