Impacts of cereal ergot in food animal production
Frontiers in Veterinary Science, 2016 The negative impacts of ergot contamination of grain on the health of humans and animals were first documented during the 5th century AD. Although ergotism is now rare in humans, cleaning contaminated grain concentrates ergot bodies in screenings which ...

Assessment of the vasoactive effects of the (S)-epimers of ergot alkaloids in vitro
Journal of Animal Science, 2020 Ergot alkaloids are produced by the fungus Claviceps purpurea and their levels are carefully monitored in animal and human diets due to their harmful effects and widespread contamination of cereal crops. Ergot alkaloids exist in two forms known as the (R)

Mycotoxin occurrence in maize silage : a neglected risk for bovine gut health? [PDF]
, 2019 Forages are important components of dairy cattle rations but might harbor a plethora of mycotoxins. Ruminants are considered to be less susceptible to the adverse health effects of mycotoxins, mainly because the ruminal microflora degrades certain ...

Differentially expressed genes in cotyledon of ewes fed mycotoxins
BMC Genomics, 2020 Background Ergot alkaloids (E+) are mycotoxins produced by the endophytic fungus, Epichloë coenophiala, in tall fescue that are associated with ergotism in animals.

Influence of Prolonged Serotonin and Ergovaline Pre-Exposure on Vasoconstriction Ex Vivo
Toxins, 2021 Ergot alkaloid mycotoxins interfere in many functions associated with serotonergic neurotransmitters. Therefore, the objective was to evaluate whether the association of serotonin (5-hydroxytryptamine, 5-HT) and ergot alkaloids during a 24 h pre ...

Neuroreceptor Activation by Vibration-Assisted Tunneling [PDF]
Scientific Reports 5, Article number: 9990 Published 2015, 2015 G protein-coupled receptors (GPCRs) constitute a large family of receptor proteins that sense molecular signals on the exterior of a cell and activate signal transduction pathways within the cell. Modeling how an agonist activates such a receptor is fundamental for an understanding of a wide variety of physiological processes and it is of tremendous ...
