CYP719A14 structure analysis and its interaction with ligands via bioinformatic methods. Methods. Homologous modeling of three-dimensional enzyme. Molecular docking. Results. enzyme, which shows cheilanthifoline synthase activity, model was build based on results homologous modeling. Interaction built possible substrates – benzylisoquinoline compounds: (S)-Scoulerine, (S)-Cheilanthifoline, (S)-...

an inactivated trivalent fowl cholera vaccine consisted of serotypes 1, 3 and 4 pasteurella multocida strains was prepared. the vaccine provided 70-100% protection against challenge with homologous starins. elisa assay showed a considerable increase in antibody titer after towice vaccination of 8 weeks chickens. it was found that the trivalent vaccine can induce immunogenic response in vaccinat...

DNA-dependent protein kinase (DNA-PK), composed of Ku70, Ku80, and the catalytic subunit (DNA-PKcs), is involved in double-strand break (DSB) repair by non-homologous end joining (NHEJ). DNA-PKcs defects confer ionizing radiation sensitivity and increase homologous recombination (HR). Increased HR is consistent with passive shunting of DSBs from NHEJ to HR. We therefore predicted that inhibitin...

We regret the incorrect designation of site attacking 3′-phosphotyrosine as 3′-hydroxyl group in process following formation Holliday junction intermediate to complete Cre/ loxP mediated recombination homologous DNA fragments.

Cattle tick control remains a serious problem for cattle farms in Brazil due to the limited success achieved with chemicals. In Brazil, the use of vaccines for tick control associated with the use of chemicals and pasture rotation may open possibilities for integrated control. However, it is important to know whether regional Boophilus microplus strains are sensitive to antibodies produced by t...
