Analysis of bulk wheat consignments for naturally-occurring contaminants and residues from plant protection products is common, and helps manage potential health risks to consumers. The heterogeneous distribution of some mycotoxins in wheat has been described, however the distribution of other contaminants and residues has not yet been reported. This study characterized distributions of deoxynivalenol, ochratoxin A, ergot alkaloids, cadmium, and glyphosate in nine large consignments of wheat by analysing composite samples representing sub-lots prepared from increments obtained during the entire loading process. The widest span of concentrations within a consignment occurred for ochratoxin A (<0.5-22.9 µg/kg) and ergot alkaloids (0.009-0.486 mg/kg), followed by deoxynivalenol (<0.05-0.76 mg/kg) and glyphosate (<0.3-5.01 mg/kg), and then cadmium (0.022-0.102 mg/kg). Experimental semivariograms were plotted to model the spatio-temporal correlation of analytes within consignments during loading. Analyses demonstrated that distributions of contaminants and residues within a particular consignment differed, and that distributions of a particular contaminant or residue differed among consignments. The results indicate that sampling during only a portion of a loading or unloading process can result in a composite sample that is not representative of the consignment and thus increase the risk of misclassifying a consignment as compliant.

Effects of exposure to chronic ergot alkaloids on phenylephrine contractile response of maternal pedal artery, umbilical artery, and umbilical vein in pregnant ewes.

Ergot alkaloids are known to cause devastating effects in livestock. The objectives of this study were to evaluate the effects of prolonged ergot exposure on selected vasculature in pregnant sheep and to examine the role of alpha-1 adrenergic receptors in mediating these effects. Twelve 60-day pregnant sheep were randomly placed into control and exposure groups (n = 6/group). Ergot-contaminated feed pellets were given orally once a day for 45 d to the exposure group [46.6 μg/kg body weight (BW) total ergot alkaloids]. The control group (Ctl) received ergot-free pellets. The maternal pedal artery from the left hindlimb and the umbilical artery and vein were dissected and mounted in a tissue bath. The vascular contractile response to a cumulatively increasing dose of phenylephrine (PE) in the exposure group (Exp) was compared with the control groups. Chronic exposure to ergot alkaloids resulted in a 70.6% and 91.3% increase in PE contractile response in the umbilical artery (Ctl EC50 = 3.962 × 10-6; Exp EC50 = 1.161 × 10-6, P < 0.0001) and the umbilical vein (Ctl EC50 = 7.889 × 10-6; Exp EC50 = 6.801 × 10-7, P < 0.0001), respectively, but there was no increase in the pedal artery (P = 0.3927), when compared to the control group. Fetal weight in the ergot-exposed group was significantly lower than in the control group (Ctl 3.3 ± 0.17 kg; Exp 2.07 ± 0.13 kg, P = 0.0002). The increase in contractile response in the umbilical vein may result in decreased blood supply to the fetus causing decreased fetal weight. Negative impact was seen at significantly lower levels of ergot alkaloids than what is currently allowed by Canadian standards, which suggests that these limits should be reevaluated to ensure livestock safety.

Evaluation of the interaction between potent small molecules against the Nipah virus Glycoprotein in Malaysia and Bangladesh strains, accompanied by the human Ephrin-B2 and Ephrin-B3 receptors; a simulation approach
Article
作者: Alijanianzadeh, Mahdi ; Ebrahimi, Maryam
Malaysia reported the first human case of Nipah virus (NiV) in late September 1998 with encephalitis and respiratory symptoms. As a result of viral genomic mutations, two main strains (NiV-Malaysia and NiV-Bangladesh) have spread around the world. There are no licensed molecular therapeutics available for this biosafety level 4 pathogen. NiV attachment glycoprotein plays a critical role in viral transmission through its human receptors (Ephrin-B2 and Ephrin-B3), so identifying small molecules that can be repurposed to inhibit them is crucial to developing anti-NiV drugs. Consequently, in this study annealing simulations, pharmacophore modeling, molecular docking, and molecular dynamics were used to evaluate seven potential drugs (Pemirolast, Nitrofurantoin, Isoniazid Pyruvate, Eriodictyol, Cepharanthine, Ergoloid, and Hypericin) against NiV-G, Ephrin-B2, and Ephrin-B3 receptors. Based on the annealing analysis, Pemirolast for efnb2 protein and Isoniazid Pyruvate for efnb3 receptor were repurposed as the most promising small molecule candidates. Furthermore, Hypericin and Cepharanthine, with notable interaction values, are the top Glycoprotein inhibitors in Malaysia and Bangladesh strains, respectively. In addition, docking calculations revealed that their binding affinity scores are related to efnb2-pem (- 7.1 kcal/mol), efnb3-iso (- 5.8 kcal/mol), gm-hyp (- 9.6 kcal/mol), gb-ceph (- 9.2 kcal/mol). Finally, our computational research minimizes the time-consuming aspects and provides options for dealing with any new variants of Nipah virus that might emerge in the future.
