Metal selective pressure in the modulation of the microbial community in sedime...
Almeida, E.; Torre, R.; Godinho, O.; Noyer, M.; Cravo-Laureau, C.; Duran, R.; Antunes, S. C.; Catita, J.; Lage, O. M.Background: Microorganisms in sediments of estuarine ecosystems play key roles in the biogeochemical cycles [1]. These communities, essential for maintaining the ecosystems quality, are affected by natural and anthropogenic factors, such as metals, affecting the ecosystems health [2]. Objectives: This work aims to understand the effect/impact of metals on brackish sediment microbial community in a mesocosm expe...
Study of metal presence in the sediments of three different water bodies from t...
Torre, R.; Pinto, I.; Lage, O. M.; Noyer, M.; Almeida, E.; Cravo-Laureau, C.; Duran, R.; Antunes, S. C.; Catita, J.Background: Human impact on the planet’s biomes has been rapidly increasing over the last decades [1]. In aquatic ecosystems, an active monitoring of the water and the sediments quality is already essential to assure its suitability for human use as well as to guarantee the health of the ecosystems [2, 3]. Objectives: This work focuses on the study of metals concentration in transitional water bodies (Ave estua...
Seed germination of six Iberian endemic species – a contribution to enhance pla...
Belo, A.D.F.; Pinto-Cruz, C.; Fernandes, M.P.; Almeida, E.; Gazarini, L.Biodiversity has been degraded all around the world due to anthropogenic factors. To counteract this worldwide tendency, ecological restoration programs are expanding. In these programs, the use of native herbaceous species, particularly those endemic or threatened, can be promoted by seeding them but germination requirements for most of these species are unknown. Our research meant to fill this gap of informat...
earlyMYCO – a mother & child pilot study to assess early-life exposure to mycot...
Martins, C.; Assunção, R.; Costa, A.; Serrano, D.; Namorado, S.; Vidigal, C.; Almeida, E.; Alvito, P.; Nunes, C.Early-life exposure occurs during gestation through transfer of toxic substances present in the maternal diet to the fetus and later during lactation, through the breast milk. Mycotoxins are well known carcinogenic, nephrotoxic, hepatotoxic, and immunosuppressive food chemical contaminants. Recently, human biomonitoring data revealed that Portuguese population is exposed to mycotoxins. These results emphasized ...
Human biomonitoring of multiple mycotoxins in biological samples of Portuguese ...
Visintin, L.; García-Nicolás, M.; Dhondt, E.; Martins, C.; Assunção, R.; Serrano, D.; Alvito, P.; Vidigal, C.; Almeida, E.; Nunes, C.; De Saeger, S.Early-life exposure to hazardous compounds is an emerging research field that urgently needs to be investigated, as an attempt to contribute to exposome research. Mycotoxins are naturally-occurring food contaminants and recent studies reported that Portuguese children (< 3 years) as well as the adult population are exposed to multiple mycotoxins through food consumption constituting a potential health threat. C...
earlyMYCO – a mother & child cohort in Portugal
Assunção, Ricardo; Martins, Carla; Costa, A.; Serrano, D.; De Boevre, Marthe; Vidal, A.; De Saeger, Sarah; Alvito, Paula; Vidigal, C.; Almeida, E.Background: Early-life exposure occurs during gestation through transfer of toxic substances present in the maternal diet to the fetus and later on, during lactation, through the breast milk. Food chemical contaminants as mycotoxins are well known carcinogenic, nephrotoxic, hepatotoxic and immunosuppressive compounds. Recent human biomonitoring data revealed that Portuguese population is exposed to mycotoxins. ...
Culturable bacteria from two Portuguese salterns: diversity and bioactive poten...
Almeida, E.; Dias, T.V.; Ferraz, G.; Carvalho, M.F.; Lage, O.M.Salterns are extreme environments, where the high salt concentration is the main limitation to microbial growth, along with solar radiation, temperature and pH. These selective pressures might lead to the acquisition of unique genetic adaptations that can manifest in the production of interesting natural products. The present study aimed at obtaining the culturable microbial diversity from two Portuguese salter...
Long-term psychological outcome after discharge from intensive care
Pereira, S.; Cavaco, S.; Fernandes, J.; Moreira, I.; Almeida, E.; Seabra-Pereira, F.; Castro, H.; Malheiro, M.; Cardoso, A.; Aragão, I.; Cardoso, T.Objective: To investigate the longterm psychological outcome in survivors of critical illness after intensive care unit discharge. Methods: A prospective cohort of survivors admitted to a mixed intensive care unit between January and September 2010 was evaluated six months and five years after hospital discharge. The Dementia Rating Scale-2, the Hospital Anxiety and Depression Scale, the Posttraumatic stress sy...

Correia, Ana Cristina; Lourenço, J.; Souta, A.; Gürbüz, B.N.; Almeida, E.; Lourenço, J.; Pereira, P.; Gomes, R.; Marques, L.; Guiné, Raquel
Current screening methodologies in drug discovery for selected human diseases
Lage, O.M.; Ramos, M.C.; Calisto, R.; Almeida, E.; Vasconcelos, V.; Vicente, F.The increase of many deadly diseases like infections by multidrug-resistant bacteria implies re-inventing the wheel on drug discovery. A better comprehension of the metabolisms and regulation of diseases, the increase in knowledge based on the study of disease-born microorganisms’ genomes, the development of more representative disease models and improvement of techniques, technologies, and computation applied ...
