Physiological consequences of exposure to heat stress and the mycotoxin zearalenone
… they induce specific, toxic effects. Zearalenone is one such mycotoxin that is particularly problematic for swine, as it is a potent phytoestrogen. As such, it can reduce productivity by disrupting reproductive processes. Although these topics are disparate, the overarching goal of …

Zearalenone contamination in swine feed and the effects on reproductive health
Zearalenone (ZEN) is an estrogenic mycotoxin produced by fungi in the genus Fusarium. Fusarium species commonly occur in cereal crops such as corn, wheat, barley, and rice which are used in swine feed. In addition to cereals, co-products of ethanol distillation, brewing, and baking are frequently …

Characterization and therapeutic alteration of the biliary excretion and enterohepatic cycling of zearalenone in sexually immature swine
The purposes of these studies were to characterize the biliary excretion and enterohepatic cycling (EHC) of zearlenone (ZEN) in young pigs and to therapeutically mimic the effect of bile removal in enhancing body clearance of ZEN. ($\sp3$H) ZEN was administered intravenously (IV), orally, and …

Investigating mechanisms of ovotoxicity of Perfluorooctanoic acid and Zearalenone exposure and the influence of altered metabolic status on ovarian function
… ovotoxicants perfluorooctanoic acid (PFOA) and zearalenone (ZEN) was investigated. The rationale for this hypothesis was based upon similar metabolic alterations including hyperinsulinemia between obesity and heat stress in females. A study to evaluate obesity-induced alterations to the ovarian …

Identification and Characterization of Novel Mycotoxin Degrading Enzymes
… Ochratoxin A was discovered. Additionally, a zearalenone hydrolase previously identified with the pipeline was biochemically characterized and demonstrated to hydrolyze additional resorcylic acid lactones beyond zearalenone, including radicicol. Radicicol inhibits the activity of Heat Shock …

Maize ear rot and associated mycotoxins in western Kenya
… and markets in Western Kenya. Deoxynivalenol, zearalenone, fumonisin and aflatoxin were detected in samples collected from the farm and markets in the region. T-2 toxin was absent in all samples collected from the region. The levels of deoxynivalenol and zearalenone detected in the samples …

DNA as a Catalyst and as a Sensor: Investigating the Structure of the Ty1 Retrotransposition Intermediate and the Utility of DNA -Based Biosensors
… have been identified for estradiol (E2) and zearalenone (ZEN). Conversion of the estradiol and zearalenone aptamers into sensors will utilize two different approaches: structure-switching signaling aptamers (switchamers) and aptazymes.

Mycotoxins Risk in Maize Fields in Relation to Insect and Edaphic Factors in South Dakota
… were positively related to deoxinivalenol and zearalenone concentrations in carbaryl-treated plots, and in untreated plots, aflatoxin and zearalenone concentrations were positively related to sap beetle kernel damage. There was no significant relationship between any mycotoxin and sap beetle …

QTL IDENTIFICATION FOR MARKER ASSISTED SELECTION OF CORN (ZEA MAYS L.) HUSK TRAITS ASSOCIATED WITH FUSARIUM SPP DISEASES RESISTANCE
… in particular fumonisins, deoxynivalenol and zearalenone. In this PHD thesis role of husk traits like husk number, husk coverage, and husk tightness have been explored to understand their possible effect in providing resistance to these pathogens. Two different experiment was conducted across …

Determination of farm animal exposure to multiple mycotoxins and assessment of novel mycotoxin binders
… basis. Results showed that deoxynivalenol (DON), zearalenone (ZEN), fumonisins (FBs), apicidin, enniatins, emodin, diacetoxyscirpenol (DAS) and beauvericin (BEV), were the most prevalent mycotoxins. Moreover, multiple linear regression analysis also revealed an interaction amongst mixtures of DON, …

Shelf-Life Improvement of Distillers Wet Grains with Solubles
… of three mycotoxins (aflatoxin, fumonisin and zearalenone) of DWGS stored under cool and warm conditions for a 7 day period were quantified.

Evaluating the emerging environmental risks of mycotoxins in freshwater ecosystems.
Deoxynivalenol (DON) and zearalenone (ZON) are two of the prominent mycotoxins which regularly contaminate food, both of these natural toxins are produced by fungi within the Fusarium genus. With the known widespread occurrence of these toxins in cereal crops there has been rising interest into the …

Mycotoxin health risk assessment modelling among maize-subsistence farmers living in Centane, Eastern Cape Province, South Africa
… as fumonisin B (FB), deoxynivalenol (DON), and zearalenone (ZEA), produced by ubiquitous food-borne fungal species, are known to contaminate maize crops from subsistence farming areas in Centane, Eastern Cape Province (EC), South Africa. The daily consumption of home-grown maize in these areas …

Is Fusarium meridionale more adapted as Gibberella Ear and Stalk Rot pathogen of maize than F. graminearum? Comparative epidemiology and toxigenicity
… equal amounts of NIV and DON (1.2:1), along with zearalenone (ZON), were found in Fmer⇾Fgra, but only NIV could be detected in the Fgra⇾Fmer treatments. These results suggested that F. meridionale was more aggressive to maize than F. graminearum. However, this experiment included only a small …
