In the present study, our aim is to investigate the preferential binding mode and encapsulation of the flavonoid fisetin in the nano-pore of β-cyclodextrin (β-CD) at the molecular level using various theoretical approaches: molecular docking, molecular dynamics (MD) simulations and binding free energy calculations. The molecular docking suggested four possible fisetin orientations in the cavity...

The therapeutic efficacy of an early treatment protocol with an infection-stage adjusted fluoroquinolone regimen was evaluated in a field study on young bulls (YBs) presenting signs of bovine respiratory disease (BRD). A total of 195 YB (Charolais, Limousin, and Rouge-des-Prés breeds) from 6 farms implementing or not prophylactic antimicrobial treatments (PROPHY or absence) were randomly assign...

Oligonucleotide-directed mutagenesis was used to produce a serine 89 to cysteine 89 substitution in the C-terminal globular domain of Escherichia coli ribosomal protein L7/L12. Cys-89 represented the only cysteine residue in the protein. L7/L12Cys89 was overproduced in E. coli and purified. An allele replacement strain was also constructed. Growth of this strain was indistinguishable from that ...
