The results indicated that both human and canine OSCC exhibited reduced levels of CDH1 and SDC1 expression at the cell membrane regardless of clinical stage or histological subtype. Additionally, decreased levels of total SDC1 expression were observed in hOSCC compared with normal controls.

We found our new method more sensitive than the previous PCRs. We also screened ectoparasite samples, collected from a poultry farm in Hungary, and three out of the eight samples were positive for S.
