CHARACTERIZATION OF OSTREOPSIS AND COOLIA (DINOPHYCEAE) ISOLATES IN THE WESTERN MEDITERRANEAN SEA BASED ON MORPHOLOGY, TOXICITY AND INTERNAL TRANSCRIBED SPACER 5.8S rDNA SEQUENCES 1
TLDR
In this study, genetic markers combined with morphology and toxicity analyses was useful in the taxonomic and phylogenetic studies of the Ostreopsidaceae in a temperate area.
Production and release of yessotoxins by the dinoflagellates Protoceratium reticulatum and Lingulodinium polyedrum in culture.
TLDR
Although YTX was detected in culture medium, with this study it was not possible to explain which is the release mechanism of the toxin in the medium, and larger amounts of toxins were observed in the cellular fraction and in the culture medium at the last stage of the culture in both species.
Dinophysis Toxins: Causative Organisms, Distribution and Fate in Shellfish
Several Dinophysis species produce diarrhoetic toxins (okadaic acid and dinophysistoxins) and pectenotoxins, and cause gastointestinal illness, Diarrhetic Shellfish Poisoning (DSP), even at low cell
Yessotoxins profile in strains of Protoceratium reticulatum from Spain and USA.
TLDR
It is demonstrated that YTX is not always the main toxin in P. reticulatum and a high variability in YTX amounts and profile found in other locations is confirmed.
A phylogeographical study of the toxic benthic dinoflagellate genus Ostreopsis Schmidt
Aim Ostreopsis is a benthic and epiphytic dinoflagellate producing potent toxins widespread in tropical and warm temperate coastal areas world-wide. We tested the hypothesis that as it is benthic, it
Yessotoxins, a Group of Marine Polyether Toxins: an Overview
TLDR
Current knowledge on the origin, producer organisms and vectors, chemical structures, metabolism, biosynthetic origin, toxicological properties, potential risks to human health and advances in detection methods of YTXs are covered.
Analysis of palytoxin-like in Ostreopsis cultures by liquid chromatography with precolumn derivatization and fluorescence detection
Abstract A rapid liquid-chromatography (LC) method is presented which uses fluorescence detection (FLD) for palytoxin analogues analysis in benthic dinoflagellates of the genus Ostreopsis. The
Mouse bioassay for palytoxin. Specific symptoms and dose-response against dose-death time relationships.
TLDR
It is demonstrated that the logistic equation and the accumulative function of Weibull's distribution generate satisfactory toxicological descriptions in all the respects.
Characterization of Prorocentrum elegans and Prorocentrum levis (Dinophyceae) from the southeastern Bay of Biscay by morphology and molecular phylogeny
TLDR
The strains mostly corresponded to their species original morphological characterization, which is supported by the phylogenetic analyses in the case of P. levis, whereas for P. elegans, this is the first known molecular characterization.
[Obesity in women].
TLDR
The role played in the pathogenesis of obesity by cyclical hormonal changes, pregnancy, the consumption of oral contraceptives and the menopause remains to be clarified and the effect of replacement hormone therapy as a cause of weight gain is doubtful.
