A critical evaluation of health risk assessment of modified mycotoxins with a special focus on zearalenone [PDF]

Mycotoxin Research, 2018
A comprehensive definition introducing the term "modified mycotoxins" to encompass all possible forms in which mycotoxins and their modifications can occur was recently proposed and has rapidly gained wide acceptance within the scientific community. It is becoming increasingly evident that exposure to such modified mycotoxins due to their presence in ...

The mycotoxin alternariol induces DNA damage and modify macrophage phenotype and inflammatory responses [PDF]

Toxicology Letters, 2015
Alternariol (AOH), a mycotoxin produced by Alternaria fungi, is frequently found as a contaminant in fruit and grain products. Here we examined if AOH could modify macrophage phenotype and inflammatory responses. In RAW 264.7 mouse macrophages AOH changed the cell morphology of from round to star-shaped cells, with increased levels of CD83, CD86, CD11b,

Evaluation of nonionic surfactant modified montmorillonite as mycotoxins adsorbent for aflatoxin B1 and zearalenone [PDF]

Journal of Colloid and Interface Science, 2018
This work aims at exploring the potential of nonionic surfactant octylphenol polyoxyethylene ether (OP-10) modified montmorillonites (NMts) as mycotoxins adsorbent. The resulting NMts has different structural configurations, organic carbon contents, surface hydrophobicity and textural properties at different surfactant loadings.

Free and Modified Mycotoxins in Organic and Conventional Oats (Avena sativa L.) Grown in Scotland

Toxins, 2023
Small grain cereals are frequently infected with mycotoxigenic Fusarium fungi. Oats have a particularly high risk of contamination with type A trichothecene mycotoxins; their glucoside conjugates have also been reported. Agronomy practices, cereal variety and weather conditions have been suggested to play a role in Fusarium infection in oats.

Determination of Mycotoxin Production of Fusarium Species in Genetically Modified Maize Varieties by Quantitative Flow Immunocytometry [PDF]

Toxins, 2017
Levels of mycotoxins produced by Fusarium species in genetically modified (GM) and near-isogenic maize, were determined using multi-analyte, microbead-based flow immunocytometry with fluorescence detection, for the parallel quantitative determination of fumonisin B1, deoxynivalenol, zearalenone, T-2, ochratoxin A, and aflatoxin B1.

Amperometric quantification of Alternaria mycotoxins with a mushroom tyrosinase modified carbon paste electrode

Electrochemistry Communications, 1999
Abstract The affinity of mushroom tyrosinase for alternariol (AOH) and alternariol monomethyl ether (AME), mycotoxins of the Alternaria alternata genus, is verified both spectroscopically and electrochemically. Commercial enzyme and fresh mushroom tissue were employed for electrochemical measurements.

Analytical tools to determine mycotoxins and modified mycotoxins

, 2018
Controlling contaminants in food is a priority for human and animal health and one of the major concerns of authorities across all over the world. In food and feed samples, small and secondary metabolites produced by filamentous fungi, known as mycotoxins, can appear.

Enzymatic synthesis of the modified mycotoxins 3-lactyl- and 3-propionyl-deoxynivalenol

Frontiers in Sustainable Food Systems
The use of lactic acid bacteria as a low-cost sustainable management tool to prevent further build-up of Fusarium mycotoxins during grain storage is increasingly propagated. It has been reported that even deoxynivalenol contamination already formed in the field can be reduced by such treatment in unknown ways.

Modified and unmodified b-cyclodextrins as mycotoxin receptors

, 2008
A great number of food matrices have been recognized as susceptible to mycotoxin contamination. The toxicological effects of these mycotoxins when ingested by animal and humans and the possibility to find them in finished products are causing great concern among producers and consumers.
