Correlation between trace element concentrations in the blood of female hawksbi...
Morão, Inês; Simões, Tiago; Busom Casado, Roger; Vieira, Sara; Ferreira-Airaud, Betânia; Caliani, Ilaria; Di Noi, Agata; Casini, Silvia; Fossi, Maria C.Metals and metalloids can pose a significant threat to sea turtles, as these contaminants tend to accumulate in their bodies over time, due to their long lifespans and varied feeding habits. São Tomé and Príncipe's archipelago hosts the last remaining rookery for hawksbill sea turtles (Eretmochelys imbricata) in the region. The study aimed to determine the levels of metals and metalloids accumulated by this pop...
Discriminative influence of persistent organic pollutants on nesting green sea ...
Morão, Inês; Muñoz-Arnanz, Juan; Simões, Tiago; Bartalini, Alice; Vieira, Sara; Ferreira-Airaud, Betânia; Caliani, Ilaria; Noi, Agata Di; Casini, SilviaPersistent organic pollutants (POPs) including polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and organochloride pesticides (OCPs) affect biodiversity by bioaccumulating through food webs, impacting marine organisms like endangered sea turtles. This study represents the first evaluation of these contaminants in sea turtles nesting in São Tomé and Príncipe. The main goal was to evaluat...

Roxo, Ana Isabel; Baptista, António; Simões, TiagoApesar da importância da preservação digital ter vindo a ser destacada por várias instituições internacionais e nacionais, esta ainda fica a cargo de cada organização. Constatámos que o Koha não tem uma forma direta para exportar os dados do Módulo de Assinaturas e que a comunidade nacional e internacional não apresenta soluções claras para fazê-lo. Adotando uma abordagem mista, pesquisámos por soluções e ident...

Metal accumulation in female green sea turtles (Chelonia mydas) from Eastern At...
Morão, Inês F.C.; Simões, Tiago; Casado, Roger B.; Vieira, Sara; Ferreira-Airaud, Betânia; Caliani, Ilaria; Noi, Agata Di; Casini, SilviaSea turtles, with their global distribution and complex life cycle, often accumulate pollutants such as metals and metalloids due to their extended lifespan and feeding habits. However, there are limited studies exploring the impact of metal pollution on the reproductive health of female sea turtles, specifically focusing on the quality of their eggs, which has significant implications for the future generation...

Asparagopsis armata exudate cocktail: the quest for the mechanisms of toxic act...
Silva, Carla; Simões, Tiago; Félix, Rafael; A.M.V.M., Soares; Barata, Carlos; Novais, Sara C.; Lemos, Marco F.L.The seaweed Asparagopsis armata exhibits a strong invasive behavior, producing halogenated compounds with effective biological effects. This study addresses the biochemical responses to sublethal concentrations of A. armata exudate on the marine snail Gibbula umbilicalis whole body and the shrimp Palaemon elegans eyes and hepatopancreas. Antioxidant defenses superoxide dismutase (SOD) and glutathione-S-transfer...
Argan oil as a rich source of linoleic fatty acid for dietetic structured lipid...
Simões, Tiago; Ferreira, Jessica; Lemos, Marco F.L.; Augusto, Ana; Félix, Rafael; Silva, Susana F.J.; Ferreira-Dias, Suzana; Tecelão, CarlaArgan oil is rich in long-chain unsaturated fatty acids (FA), mostly oleic and linoleic, and natural antioxidants. This study addresses the production of low-calorie structured lipids by acidolysis reaction, in a solvent-free system, between caprylic (C8:0; system I) or capric (C10:0; system II) acids and argan oil, used as triacylglycerol (TAG) source. Three commercial immobilized lipases were tested: Novozym®...
Exposure to the insecticide sulfoxaflor affects behaviour and biomarkers respon...
Damasceno, Jadilson M.; Rato, Lénia D.; Simões, Tiago; Morão, Inês F. C.; Meireles, Gabriela; Novais, Sara C.; Lemos, Marco F.L.Sulfoxaflor is an insecticide belonging to the recent sulfoximine class, acting as a nicotinic acetylcholine receptor (nAChRs) agonist. There are few studies regarding sulfoxaflor’s toxicity to non-target organisms. The present study aimed to investigate the acute and sub-lethal effects of sulfoxaflor on Carcinus maenas by addressing survival, behaviour (feed intake and motricity), and neuromuscular, detoxifica...
