okadaic acid/vomiting

Diarrhetic shellfish poisoning (DSP) is a gastrointestinal illness with symptoms such as diarrhea, nausea, vomiting, headache, chills and moderate to severe abdominal pain. DSP has been recognized as a worldwide public health problem, causing great concern to the shellfish industry. Accumulation of

The lipophilic marine biotoxin okadaic acid (OA) represents a natural contaminant produced by algae accumulating in seafood. Acute intoxications result in diarrhetic shellfish poisoning causing symptoms like nausea, vomiting and abdominal cramps. OA was preincubated with liver enzymes present in S9

The biotoxin okadaic acid (OA), produced by dinoflagellates in marine environment, can accumulate in sponges and shellfish. Consumption of contaminated shellfish induces acute toxic effects such as diarrhea, nausea, vomiting, and abdominal pain. CYP3A4, one of the most important human xenobiotic

The consumption of okadaic acid (OA) contaminated shellfish can induce acute toxic symptoms in humans such as diarrhea, nausea, vomiting and abdominal pain; carcinogenic and embryotoxic effects have also been described. Toxicokinetic studies with mice have shown that high cytotoxic doses of OA can

Okadaic acid (OA), a marine toxin produced by dinoflagellates, can accumulate in various bivalve molluscs. In humans, consumption of OA induces acute toxic effects like diarrhoea, nausea, vomiting and abdominal pain. OA is a potent inhibitor of protein phosphatase 1 (PP1) and 2A (PP2A), enzymes that

The marine toxin okadaic acid (OA) is the main representative of diarrhoeic shellfish poisoning (DSP) toxins. Its ingestion induces nausea, vomiting, diarrhoea and abdominal ache. It has also been found to trigger cellular and molecular effects at low concentrations. Its mechanism of action has not

The marine biotoxin okadaic acid (OA), produced by dinoflagellates, can accumulate in various bivalve molluscs. In humans, oral consumption of shellfish contaminated with OA induces acute toxic effects like diarrhea, nausea, vomiting and abdominal pain. However, tumorigenic and embryotoxic effects

The ingestion of seafood contaminated with the marine biotoxin okadaic acid (OA) can lead to diarrhetic shellfish poisoning with symptoms like nausea, vomiting and abdominal cramps. Both rat and the human hepatic cytochrome P450 monooxygenases (CYP) metabolize OA. However, liver cell toxicity of

In Antwerp, Belgium, 403 cases of diarrhoeic shellfish poisoning were reported after consumption of blue mussels. Symptoms included diarrhoea, vomiting, abdominal pain, and nausea. The analysis of faecal specimens from patients allowed diagnosis exclusions for bacteria and viruses. Mouse-assays

OBJECTIVE This investigation was undertaken in response to an outbreak of suspected shellfish poisoning in Zhejiang Province, China. The objectives of this project were to confirm the outbreak and to identify the aetiology, source and mode of transmission. METHODS A probable case was defined as an

Diarrhetic shellfish poisoning (DSP) is a serious and globally widespread phytoplankton-related seafood illness. Although DSP is rarely life-threatening, it causes incapacitating diarrhea and vomiting with no known medical treatments. In addition, phytoplankton producing DSP toxins have been

Okadaic acid (OA) is a low-molecular-weight marine toxin from shellfish that causes abdominal pain, vomiting and diarrhea, i.e., diarrheic shellfish poisoning. In this study, a ssDNA aptamer that specifically binds to OA with high affinity was obtained via Systematic Evolution of Ligands by
