[Dynamic tracheal collapse in a wagyu calf with multiple rib fractures after dystocia].

A dynamic tracheal collapse caused by multiple rib fractures in a neonatal wagyu calf was diagnosed by radiography, endoscopy and computed tomography. Conservative treatment, consisting of the medical treatment of respiratory inflammation and the reduction of environmental and social stress was initiated. The respiratory signs improved significantly, and the calf was discharged.

In vitro effects of Type I interferons (IFNτ and IFNα) on bovine hepatocytes cultured with or without Kupffer cells.

In cattle, maternal recognition of early pregnancy depends on the effects of the embryonic signal interferon (IFN)-τ. IFN-stimulated genes have been upregulated in the maternal liver during early pregnancy. In this study, primary hepatocyte cell culture models were evaluated for their suitability to test Type I IFN effects invitro.
