Mushrooms provide essential nutrients and bioactive compounds, namely glucans, protein, and phenolic compounds. In this study, two aqueous extractions were performed (M1 and M2) using Pleurotus ostreatus, Pleurotus eryngii, and Agrocybe cylindracea. In M1, a hot extraction (extract M1) (90 °C, 700 rpm, 1 h) was performed. In M2, a room-temperature extraction (extract M2A) followed by a hot extraction (extract M...
Oceanic island ecosystems are particularly vulnerable to the impacts of introduced mammalian predators. Among these, free-ranging cats (Felis catus) are especially detrimental, and have been linked to the extinction and population decline of numerous insular taxa. Yet, a more holistic understanding of the impacts of free-ranging cats has been hampered by an incomplete understanding of their diet and population ...
RESUMO: São apresentados os geossítios portugueses que integram a lista dos Primeiros 100 Sítios de Património Geológico da IUGS. A lista resulta de um projeto patrocinado pelo IGCP-UNESCO e pela IUGS, com o objetivo de sensibilizar para a importância das estratégias de geoconservação, para a expansão do conhecimento geológico e para a proteção do património geológico com excecional valor científico e que corre...
Experiences of life-threatening stimuli can induce post-traumatic stress disorder (PTSD), which is associated with long-lasting behavioral and neurochemical abnormalities. Despite its increased global incidence, the current treatment options for PTSD remain limited, highlighting the need for novel therapeutic strategies. As oxidative stress and neuroinflammation contribute to PTSD, the use of powerful antioxida...
Os acidentes ofídicos em Portugal são raros, mas potencialmente graves. Relatamos um caso de mordedura por víbora com envolvimento local e sistémico com critérios para administração de antiveneno. O envenenamento foi atribuído a Vipera latastei, com veneno de ação hemo e citotóxica, causador de necrose tecidular, coagulopatia e lesão renal aguda. Este caso sublinha a importância do diagnóstico precoce, da abord...
Among the most significant and productive agroindustries worldwide is the wine business. This agroindustry generates millions of tons of biological residues, carrying huge negative impacts related to the disposal of these materials into the environment. Nevertheless, these byproducts present a high potential for developing new products, contributing to the circularity of this economic sector. In this study, the...
Os incêndios rurais são um fenómeno recorrente em Portugal. Muitas vezes as cinzas produzidas por estes incêndios atingem as massas de água utilizadas para o abastecimento público, comprometendo a sua qualidade. Num exemplo recente, as cinzas resultantes dos incêndios de 2017 levaram à interrupção do abastecimento de água a algumas localidades, e à implementação de programas de monitorização adicional em outras...

The InBIO Barcoding Initiative (IBI) Dataset - DS-IBILP08 contains records of 2350 specimens of moths (Lepidoptera species that do not belong to the superfamily Papilionoidea). All specimens have been morphologically identified to species or subspecies level and represent 1158 species in total. The species of this dataset correspond to about 42% of mainland Portuguese Lepidoptera species. All specimens were col...
Nowadays, plant-based bioactive compounds (BCs) are a key focus of research, supporting sustainable food production and favored by consumers for their perceived safety and health advantages over synthetic options. Lavandula pedunculata (LP) is a Portuguese, native species relevant to the bioeconomy that can be useful as a source of natural BCs, mainly phenolic compounds. This study compared LP polyphenol-rich e...
