Journal ArticleDOI

Toxins of cyanobacteria

TL;DR: Toxicity data on cyanotoxins are rather scarce, and a majority of toxicity data are known to be of microcystin-LR, while for nodularins, data from a few animal studies are available.
Journal ArticleDOI

Masked mycotoxins: A review

TL;DR: The aim of this review is to give a comprehensive overview of the current knowledge on plant metabolites of mycotoxins, also called masked mycot oxins, which are secondary fungal metabolites, toxic to human and animals, and their impact on stakeholders.
Journal ArticleDOI

Safety assessment of botanicals and botanical preparations used as ingredients in food supplements: testing an European Food Safety Authority-tiered approach.

TL;DR: Results obtained by testing the European Food Safety Authority-tiered guidance approach for safety assessment of botanicals and botanical preparations intended for use in food supplements result in the conclusion that safety can be presumed, that the botanical ingredient is of safety concern, or that further data are needed to assess safety.
Journal ArticleDOI

Subacute toxicity of α-ergocryptine in Sprague–Dawley rats. 2: metabolic and hormonal changes

TL;DR: It is postulated that the observed effects on food intake, metabolism (lipid and carbohydrate) and hormonal parameters are due to an interaction of ergocryptine with central dopaminergic activities, which comprise a major functional component of a central regulatory system for metabolism.
