BACKGROUND Canine hemangiosarcoma (HSA) is a malignant tumor with poor long-term prognosis due to development of metastasis despite aggressive treatment. The phosphatidyl-inositol-3 kinase/Akt/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway is involved in its endothelial pathologies; however, it remains unknown how this pathway plays a role in canine HSA. Here, we characterized new canine...

A monoclonal antibody, K9BYU, was generated using Escherichia coli recombinant extracellular domain of canine neural-cell adhesion molecule (N-CAM) as an antigen. Immunoreactivity of K9BYU to insect cell recombinant canine N-CAM was demonstrated by Western blotting using Sf9 insect cells transfected with the canine N-CAM gene. In Western blotting against canine brain tissue, K9BYU detected thre...

The distribution of the nonstructural protein 1 (NSP1) alleles from human strain AU-1 and canine strain K9 among rotaviruses of human, feline, canine, bovine, and simian origin was studied by a dot blot hybridization assay. Human and feline strains belonging to the AU-1 genogroup had the same NSP1 allele, while canine and feline strains belonging to the canine-feline genogroup shared another NS...

The results of this study confirmed that dogs vaccinated subcutaneously with a commercially available multivalent vaccine containing modified-live canine distemper virus, canine adenovirus type 2, canine parvovirus type 2b, and canine parainfluenza virus antigens were protected against sequential experimental challenge 55 to 57 months after initial vaccination given at 7 to 8 weeks of age. All ...

BACKGROUND To evaluate the effectiveness of two minimally invasive surgical procedures in the acceleration of canine retraction: piezocision and laser-assisted flapless corticotomy (LAFC). METHODS Trial design: A single-centre randomized controlled trial with a compound design (two-arm parallel-group design and a split-mouth design for each arm). PARTICIPANTS 36 Class II division I patients...

PURPOSE Mutations in PAX6 cause human aniridia. The small eye (sey) mouse represents an animal model for aniridia. However, no large animal model currently exists. We cloned and characterized canine PAX6, and evaluated PAX6 for causal associations with inherited aniridia in dogs. METHODS Canine PAX6 was cloned from a canine retinal cDNA library using primers designed from human and mouse PAX6...

Simultaneous infection of canine distemper virus and canine parvovirus associated with distemper myocardial degeneration and necrosis is described in a pup. The dog demonstrated myoclonus, nystagmus, enamel hypoplasia, abdominal pustules, and bilateral corneal ulceration clinically. Demyelinating encephalitis, myocardial degeneration and necrosis with mineralization, and necrosis, hemorrhage an...

To rapidly distinguish Canine distemper virus (CDV), canine parvovirus (CPV), and canine kobuvirus (CaKoV) in practice, a one-step multiplex PCR/RT-PCR assay was developed, with detection limits of 102.1 TCID50 for CDV, 101.9 TCID50 for CPV and 103 copies for CaKoV. This method did not amplify nonspecific DNA or RNA from other canine viruses. Therefore, the assay provides a sensitive tool for t...

This paper describes the cloning and sequence analysis of the cDNAs encoding the canine homologues of interleukin-3 (IL-3) and interleukin-6 (IL-6). The coding sequences for canine IL-3 and IL-6 were obtained by using the reverse transcription polymerase chain reaction (RT-PCR) with RNA harvested from canine peripheral blood mononuclear cells (PBMCs). Canine IL-3 cDNA includes a single open rea...
