Combining an effect-based methodology with chemical analysis for antibiotics determination in wastewater and receiving freshwater and marine environment
(Elsevier, 2020-12-15)
Two different methodologies were combined to evaluate the risks that antibiotics can pose in the environment; i) an effect-based methodology based on microbial growth inhibition and ii) an analytical ...
β-cyclodextrin polymer as tetrodotoxins scavenger in oyster extracts
(Elsevier, 2024-04-16)
Tetrodotoxins (TTXs) are potent marine neurotoxins involved in poisoning cases in humans after consumption of some marine organisms. A cell-based assay (CBA) providing toxicological information is a ...
A smartphone-controlled amperometric immunosensor for the detection of Pacific ciguatoxins in fish
(Elsevier, 2021-12-02)
Ciguatoxins (CTXs) are marine neurotoxins produced by microalgae of the genera Gambierdiscus and Fukuyoa. CTXs may reach humans through food webs and cause ciguatera fish poisoning (CFP). An immunosensor ...
Rapid screening and multi-toxin profile confirmation of tetrodotoxins and analogues in human body fluids derived from a puffer fish poisoning incident in New Caledonia
(Elsevier, 2017-12-30)
In August 2014, a puffer fish poisoning incidence resulting in one fatality was reported in New Caledonia. Although tetrodotoxin (TTX) intoxication was established from the patients' signs and symptoms, ...
Detoxification of paralytic shellfish poisoning toxins in naturally contaminated mussels, clams and scallops by an industrial procedure
(Elsevier, 2020-05-04)
Paralytic shellfish poisoning (PSP) episodes cause important economic impacts due to closure of shellfish production areas in order to protect human health. These closures, if are frequent and persistent, ...
First record of paralytic shellfish toxins in marine pufferfish from the Spanish Mediterranean coast using cell-based assay, automated patch clamp and HPLC-FLD
(Elsevier, 2024-08-08)
Pufferfish is one of the most poisonous marine organisms, responsible for numerous poisoning incidents and some human fatalities due to its capability to accumulate potent neurotoxins such as tetrodotoxins ...
Toxicity Equivalency Factors for Tetrodotoxin Analogues Determined with Automated Patch Clamp on Voltage-Gated Sodium Channels in Neuro-2a Cells
(American Chemical Society, 2024-08-05)
Tetrodotoxin (TTX) is a potent marine neurotoxin, responsible for numerous poisoning incidents and some human fatalities. To date, more than 30 TTX analogues have been identified, but their individual ...
Immobilisation of Neuro-2a cells on electrodes and electrochemical detection of MTT formazan crystals to assess their viability
(Elsevier, 2022-09-24)
Marine toxins are potent toxic compounds that may reach humans and poison them. Therefore, their detection in seafood is crucial to prevent intoxication cases. Colorimetric cell-based assays (CBAs) have ...
