AbstractOkadaic acid (OA), a major polyether toxin involved in diarrhetic shellfish poisoning (DSP), is a potent tumor promoter in rodent skin and glandular stomach and a specific inhibitor of the serine/threonine protein phosphatases PP1 and PP2A. A previous study, which used the cytokinesis‐block micronucleus (CBMN) assay in CHO‐K1 cells, showed that

Toxins from Fish and other Marine Organisms
1970Publisher Summary Sea creatures from virtually all marine phyla have been a source of food for humans from the earliest days of history, as soon as man began to explore his aquatic environment. Although, fish and shellfish have always been the principal objects of man's harvest from the sea, consumption of such diverse organisms as algae, echinoderms,

Targeting Marine Toxins and Other Adulterants in Fish
2019Seafood quality is directly related to the condition of the water from which it originates. Concerted efforts are being made by government bodies to ensure the best-quality seafood reaches consumers, but this is an ongoing and evolving struggle as climates and environments are changing, the global population is increasing and the marine environment is ...

Marine Biology, 1981
Marine fishes (Atlantic herring, American pollock, winter flounder, Atlantic salmon, and cod) were dosed orally and intraperitoneally (i.p.) with “paralytic shellfish toxins” extracted from Bay of Fundy Gonyaulax excavata (tamarensis) cells. The toxins are lethal to these fishes in low oral doses, and in extremely low i.p. doses.

ABSTRACT The margin of safety between shelf‐life (onset of sensory spoilage) and potential time to toxin production by Clostridium botulinum type E in retail type packages of fresh marine cod fillets packaged in high barrier film under selected atmospheres [100% air, a modified atmosphere (MA) containing 75% CO2:25% N2, and vacuum] and stored under ...

Fish and Fisheries, 2014
AbstractFish are frequently exposed to paralytic shellfish toxins (PSTs) derived from harmful algal blooms (HAB). PSTs are potent neurotoxins with strong effects on fish at multiple trophic levels. Here, we examine the historical and contemporary mass mortality events combining with the available data on response of fish to PSTs' exposure.

Nel corso dei tre anni del progetto stati portati avanti e definiti gli obiettivi previsti dal progetto stesso, con il coinvolgimento delle diverse UO. Uno dei principali obiettivi è stato quello di effettuare uno studio sulla distribuzione delle alghe tossiche nelle acque e di biotossine nei prodotti ittici del territorio nazionale allo scopo di ...
