Uninvited guests: New stored mangrove rice insect pests in Guinea-Bissau
Conde, Sofia; Monteiro, Filipa; Catarino, Sílvia; Ferreira, Maria Rosa; Ferreira, SóniaMangrove swamp rice is vital for food security in Guinea-Bissau, yet insect infestations cause significant post-harvest losses worldwide. This study identified insect pests affecting stored rice seeds using both morphological identification and DNA barcoding. In 2022, 64 rice samples were collected from 13 villages across 3 coastal regions yielding 1504 insect specimens, classified into 13 morphotypes from Cole...
Nutritional and Biochemical Assessment of Edible Fruits From Angola's Native Flora
Rangel, Josefa; Liberal, Ângela; Pires, Tânia C.S.P.; Finimundy, Tiane C.; Barros, Lillian; Monteiro, Filipa; Romeiras, Maria M.; Fernandes, ÂngelaAngola's native flora hides a wealth of underexplored edible fruits with significant nutritional and bioactive potential. This study provides a comprehensive evaluation of the physicochemical and bioactive potential of some less explored edible fruits from this country, namely Annona muricata, A. squamosa, A. senegalensis, A. boehmii, Dacryodes edulis, and Strychnos spinosa. Nutritional profiling revealed carbo...

António, Rafael; Martins, Ana João; Cordeiro, Inês; Feijão, Eduardo Onofre; Matos, Ana Rita; Monteiro, Filipa; Sebastiana, MónicaCurrent studies show a decline in soil biodiversity, which puts at risk future food production since soil organisms play a key role in essential ecosystem functions such as, nutrient cycling and soil fertility, soil carbon sequestration, climate regulation, litter decomposition, erosion, water retention, interaction with plants, among others. This study aims to evaluate how the conversion of a tropical native f...

Conde, Sofia; Barai, Amidu; Catarino, Sílvia; Costa, Gonçalo J.; Ferreira, Sónia; Tavares, Idília; Ferreira, Maria Rosa; Temudo, Marina PadrãoRice cultivation is one of the most important agro-economic activities in many countries, and the correct seed storage between production cycles is essential for crop success. In Guinea- Bissau, mangrove swamp rice (MSR) is a highly productive rice cropping system, thus providing surplus for sale. Depending on storage conditions, rice grains may present moisture, insects, or the development of fungi that might ...
At the tipping point: Can biodiversity and rural livelihoods endure uncontrolle...
Guedes, Patrícia; Palmeirim, Ana Filipa; Monteiro, Filipa; Catarino, Luís; Palma, Luís; Temudo, Marina P.; Henriques, Mohamed; Beja, PedroOur commentary explores the increase in cashew cultivation across West Africa, drawing attention to its impacts on biodiversity and livelihoods. We summarize the issue regionally, then showcase Guinea-Bissau, where we unravel the dynamics between cashew expansion, habitat and biodiversity loss, and livelihoods. Finally, we propose concrete policy measures encompassing strengthened conservation, sustainable land...
Insights into the cashew production system in Guinea-Bissau: implications for a...
Sierra-Baquero, Paola Vanessa; Catarino, Sílvia; Costa, Gonçalo João; Barai, Amidu; Correia, Zinha; Ferreira, Maria Rosa; Varón-Devia, EdgarIntroduction: West Africa, particularly Guinea-Bissau, heavily relies on cashew nut (Anacardium occidentale L.) production, which significantly impacts the countries’ economies. Cashew exhibits remarkable adaptability to impoverished and arid soils. Understanding producers’ socio-economic characteristics is crucial due to their potential influence on crop productivity and household income. Methods: This study a...

Síndrome Cerebelar Rapidamente Progressiva: Um Caso Clínico
Santos, Leticia; Monteiro, Filipa; Marquês, Maria Inês; Valadão, Catarina; Delerue, FranciscaA síndrome cerebelar rapidamente progressiva é a segunda apresentação neurológica paraneoplásica mais frequente e a elevada suspeita clínica e a exclusão de outras etiologias é essencial no diagnóstico. Este pode preceder o da neoplasia e apresentar efeitos dramáticos, independentemente do estadiamento da neoplasia. É apresentado o caso de uma mulher de 69 anos foi hospitalizada por quadro com algumas semanas d...

Umbilical-Cord-Derived Mesenchymal Stromal Cells Modulate 26 Out of 41 T Cell S...
Laranjeira, Paula; Dos Santos, Francisco; Salvador, Maria João; Simões, Irina N.; Cardoso, Carla M. P.; Silva, Bárbara M.; Henriques-Antunes, HelenaSystemic sclerosis (SSc) is an immune-mediated disease wherein T cells are particularly implicated, presenting a poor prognosis and limited therapeutic options. Thus, mesenchymal-stem/stromal-cell (MSC)-based therapies can be of great benefit to SSc patients given their immunomodulatory, anti-fibrotic, and pro-angiogenic potential, which is associated with low toxicity. In this study, peripheral blood mononucle...
