      The importance of ciguatoxins (CTXs) in seafood safety and their emerging occurrence in locations far away from tropical areas highlight the need for simple and low-cost methods for the sensitive and ...

    • Bioaccessibility of lipophilic and hydrophilic marine biotoxins in seafood: An in vitro digestion approach 

      Alves, Ricardo N.; Rambla-Alegre, Maria; Braga, Ana Catarina; Maulvault, Ana L.; Barbosa, Vera; Campàs, Mònica; Reverté, Laia; Flores, Cintia; Caixach, Josep; Kilcoyne, Jane; Costa, Pedro Reis; Diogène, Jorge; Marques, António (Food and Chemical Toxicology, 2019-04-28) Aigües Marines i Continentals
      This study aimed to assess the bioaccessibility of different marine biotoxins in naturally contaminated shellfish and fish gonads using an in vitro digestion methodology. In general, hydrophilic toxins ...

    • Detection of tetrodotoxins in juvenile pufferfish Lagocephalus sceleratus (Gmelin, 1789) from the North Aegean Sea (Greece) by an electrochemical magnetic bead-based immunosensing tool 

      Leonardo, Sandra; Kiparissis, Sotiris; Rambla-Alegre, Maria; Almarza, Sergi; Roque, Ana; Andree, Karl B.; Christidis, Aris; Flores, Cintia; Caixach, Josep; Campbell, Katrina; Elliott, Christopher T.; Aligizaki, Katerina; Diogène, Jorge; Campàs, Mònica (Food Chemistry, 2019-03-29) Aigües Marines i Continentals; Aqüicultura
      Two small Lagocephalus sceleratus juveniles were captured in picarel targeting catches from North Aegean Sea (Greece) in the autumn of 2017. An electrochemical immunosensing tool using magnetic beads ...

    • Identification of ciguatoxins in a shark involved in a fatal food poisoning in the Indian Ocean 

      Diogène, Jorge; Reverté, Laia; Rambla-Alegre, Maria; del Río, Vanessa; de la Iglesia, Pablo; Campàs, Mònica; Palacios, Oscar; Flores, Cintia; Caixach, Josep; Ralijaona, Christian; Razanajatovo, Iony; Pirog, Agathe; Magalon, Hélène; Arnich, Nathalie; Turquet, Jean (Scientific Reports, 2017-08-15) Aigües Marines i Continentals
      Severe food poisoning events after the consumption of sharks have been reported since the 1940s; however, there has been no clear understanding of their cause. Herein, we report for the frst time ...

    • Identification of New CTX Analogues in Fish from the Madeira and Selvagens Archipelagos by Neuro-2a CBA and LC-HRMS
