Special Issue Information

Dear Colleagues,

The assessment of the risk for a given mycotoxin is based on risk characterization, combining three major pillars: hazard identification, hazard characterization, and exposure assessment. In this Special Issue we would like to focus on the first two pillars, aiming to identify and characterize the risk of a given mycotoxin by assessing both its toxicokinetics and its toxicity or toxicodynamics. Toxicokinetics include the so-called ADME processes (i.e., absorption, distribution, metabolism, and excretion), and determines the rate and extent at which the disposition of a toxin takes place. The toxicokinetic properties of a given toxin reflect its absolute internal dose, and comprise processes such as gastric and intestinal stability, rate and extent of oral absorption, presystemic elimination (first pass, metabolism in gut and/or liver), systemic elimination (metabolism and excretion) determining the total body clearance, and specific biological barriers determining the volume of distribution. Each of these processes may show species-specific differences. Next, toxicodynamics describe the toxicological characteristics (among others, cytotoxicity, genotoxicity (mutagenicity and carcinogenicity), mode of action, and dose–response relationship) of mycotoxins. Besides mycotoxin risk assessment, a toxicokinetic and toxicodynamic approach can also be applied to define the efficacy, mode of action, and safety of mycotoxin mitigation strategies.

This Special Issue aims to gather innovative research on toxicokinetics, toxicity, or toxicodynamics, and the integration of toxicokinetic and toxicodynamic processes of mycotoxins in animals and humans, such as papers describing the toxicokinetic properties of emerging mycotoxins, mycotoxin metabolites, or comparative inter-species approaches, as well as new approaches and alternatives for toxicity testing and toxicokinetic/toxicodynamic approaches to evaluating postharvest mycotoxin mitigation strategies.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxins is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs).

Calcination Improves the In Vivo Efficacy of a Montmorillonite Clay to Bind Aflatoxin G1 in Broiler Chickens: A Toxicokinetic Approach

The goal of this study was to investigate the toxicokinetic characteristics of aflatoxin G1 (AFG1) in broiler chickens and the effect of calcination of a Tunisian montmorillonite clay on the in vivo absorption of AFG1. In this study, broiler chickens were randomly distributed into four groups of 10 animals. Group 1 was administered AFG1 (2 mg/kg body weight (BW)) by single intravenous injection (IV), group 2 received an intra-crop bolus (PO) of AFG1 without any clay, group 3 was dosed AFG1 PO together with an oral bolus of purified clay (CP), and group 4 received AFG1 PO with an oral bolus of calcined clay. A significant difference in the area under the curve (AUC0-t) was observed for group 4 (6.78 ± 4.24 h*ng/mL) in comparison with group 2 (12.83 ± 4.19 h*ng/mL). A significant reduction of the oral bioavailability of AFG1 was observed for group 4 (7.61 ± 4.76%) compared with group 2 (14.40 ± 4.70%), while no significant effect was observed of CP. In this experiment, no phase I nor phase II metabolites of AFG1 were observed. These findings confirm that calcination of the purified montmorillonite clay enhances the adsorption of AFG1 in the gastrointestinal tract after oral administration, thereby reducing its bioavailability, thus reducing its toxic effects.
