Genetic characterization of bovine respiratory syncytial viruses in Japan between 2017 and 2019.

Bovine respiratory syncytial virus (BRSV) strains that were detected in Kagoshima prefecture and isolated in Hokkaido between 2017 and 2019, together with a BRSV vaccine strain, were subjected to full-genome sequencing. The BRSV strains identified in Japan were found to be genetically close to each other but distant from the vaccine strains. The deduced amino acids at positions 206 and 208 of the glycoprotein (G protein), which form one of the major epitopes of the recent Japanese BRSV strains, were different from those of the vaccine strains.

Inhibitory effects of trientine, a copper-chelating agent, on induction of DNA strand breaks in kidney cells of Long-Evans Cinnamon (LEC) rats.

The effects of treatment with trientine, a specific copper-chelating agent, on the accumulation of copper and induction of DNA strand breaks were investigated in Long-Evans Cinnamon (LEC) rats, an animal model for human Wilson's disease. Copper accumulated in the kidneys of LEC rats in an age-dependent manner from 12 to 18 weeks of age. When LEC rats were treated with trientine from 10 weeks of age, renal copper contents did not increase and were maintained at the same levels as those in 4-week-old LEC rats.

Inhibitory effects of trientine, a copper-chelating agent, on induction of DNA strand breaks in hepatic cells of Long-Evans Cinnamon rats.

Effects of treatment with trientine, a specific copper-chelating agent, on accumulation of copper and induction of DNA strand breaks were investigated in Long-Evans Cinnamon (LEC) rats, an animal model for human Wilson's disease. Copper accumulated in the livers of LEC rats in an age-dependent manner from 4 to 13 weeks of age. When LEC rats were treated with trientine from 10 weeks of age, hepatic copper contents did not increase and were maintained at the same levels as those in 10-week-old LEC rats.
