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...
Harnessing AI and NLP tools for innovating brand name generation and evaluation...
Lemos, Marco; Cardoso, Pedro; Rodrigues, JoaoThe traditional approach of single-word brand names faces constraints due to trademarks, prompting a shift towards fusing two or more words to craft unique and memorable brands, exemplified by brands such as SalesForce (c) or SnapChat (c). Furthermore, brands such as Kodak (c), Xerox (c), Google (c), H & auml;agen-Dazs (c), and Twitter (c) have become everyday names although they are not real words, underscorin...
Ecotoxicological effects of the anionic surfactant Sodium Dodecyl Sulfate (SDS)...
Cruz de Carvalho, Ricardo; Feijão, Eduardo; Matos, Ana; Cabrita, Maria Teresa; Utkin, Andrei; Novais, Sara; Lemos, Marco; Caçador, Isabel; Marques, JoãoSodium Dodecyl Sulfate (SDS) is an anionic surfactant, extensively used in detergents, household and personal care products, as well as in industrial processes. The present study aimed to disclose the potential toxicological effects of SDS exposure under environmentally relevant concentrations (0, 0.1, 1, 3, and 10 mg L−1 ) on the physiology and biochemistry (photosynthesis, pigment, and lipid composition, anti...
Epigenetics in aquaculture - the last frontier
Granada, Luana; Lemos, Marco; Cabral, Henrique; Bossier, Peter; Novais, SaraAquaculture production is expanding rapidly around the world. To tackle rising production and species diversity issues, innovations in the field of aquaculture feeds, breeding, disease management and other improvements must be addressed. In this framework, the study of epigenetic mechanisms behind different aquaculture rearing processes presents great opportunities. The transcriptional impact of epigenetic modi...
An Insight into Sargassum muticum Cytoprotective Mechanisms against Oxidative S...
Pinteus, Susete; Lemos, Marco; Silva, Joana; Alves, Celso; Neugebauer, Agnieszka; Freitas, Rafaela; Duarte, Adriana; Pedrosa, RuiSargassum muticum is a brown seaweed with strong potential to be used as a functional food ingredient, mainly due to its antioxidant properties. It is widely used in traditional oriental medicine for the treatment of numerous diseases. Nevertheless, few studies have been conducted to add scientific evidence on its effects as well as on the mechanisms of action involved. In this work, the human cell line MCF-7 w...
Thermal stress effects on energy resource allocation and oxygen consumption rat...
Kühnhold, Holger; Kamyab, Elham; Novais, Sara; Indriana, Lisa; Kunzmann, Andreas; Slater, Matthew; Lemos, MarcoWater temperature is a key factor in aquaculture production of the commercially valuable sea cucumber Holothuria scabra. Knowledge is scarce about actual energetic costs that can be associated with internal acclimatization processes as a response to thermal extremes. In the present study changes in cellular energy allocation, oxygen consumption rate and energy related enzymes' activity (IDH and LDH) were measur...
MarinEye – A tool for marine monitoring
Martins, Alfredo; Dias, André; Silva, Eduardo; Ferreira, Hugo; Dias, Ireneu; Almeida, José Miguel; Torgo, Luís; Gonçalves, Marco; Guedes, MaurícioThis work presents an autonomous system for marine integrated physical-chemical and biological monitoring – the MarinEye system. It comprises a set of sensors providing diverse and relevant information for oceanic environment characterization and marine biology studies. It is constituted by a physical-chemical water properties sensor suite, a water filtration and sampling system for DNA collection, a plankton i...

Compounds altering fat storage in Daphnia magna
Jordão, Rita; Garreta, Elba; Campos, Bruno; Lemos, Marco; Soares, Amadeu M.V.M.; Tauler, Romà; Barata, CarlosThe analysis of lipid disruptive effects in invertebrates is limited by our poor knowledge of the lipid metabolic pathways. A recent study showed that tributyltin activated the ecdysteroid, juvenile hormone and retinoic X receptor signaling pathways, and disrupted the dynamics of neutral lipids in the crustacean Daphnia magna impairing the transfer of triacylglycerols to eggs and hence promoting their accumulat...
Using the mini-VIDAS® Easy Salmonella protocol to assess contamination in trans...
Rodrigues, M. J.; Martins, K.; Garcia, D.; Ferreira, Susana; Gonçalves, Sílvia; Mendes, S.; Lemos, MarcoClassical methodologies for Salmonella detection may be too long in time to assure public safety. Presently, one of the fastest assays for Salmonella detection using the mini-VIDAS® system is the Easy Salmonella protocol. This assay, developed for food matrixes analysis, was here assessed for the applicability on the detection of these bacteria in transitional and saltwaters. The presence of Salmonella was dete...
