Pharmacokinetics and tolerance of repeated oral administration of 5-fluorocytosine in healthy dogs.

Background: 5-fluorocytosine is a pyrimidine and a fluorinated cytosine analog mainly used as an antifungal agent. It is a precursor of 5-fluorouracil, which possesses anticancer properties. To reduce systemic toxicity of 5-fluorouracil during chemotherapy, 5- fluorocytosine can be used as a targeted anticancer agent.

Endoscopic assessment of presumed acquired pyloric narrowing in cats: A retrospective study of 27 cases.

Acquired pyloric narrowing is a rare and poorly-documented condition in cats, but the endoscopic appearance of pyloric narrowing has never previously been reported. The objectives of this study were to describe the clinical, endoscopic and histological features in cats with gastrointestinal signs where the pylorus could not be passed during endoscopy, and to compare these data with a control group. Medical files of cats that underwent upper GI endoscopy by the same operator between 2006 and 2015 were reviewed.

Prognostic value of somatic focal amplifications on chromosome 30 in canine oral melanoma.

Canine oral melanoma is the first malignancy of the oral cavity in dogs and is characterized by a local invasiveness and a high metastatic propensity. A better knowledge of genetic alterations is expected to improve management of this tumour. Copy number alterations are known characteristics of mucosal melanomas both in dogs and humans.

Naturally occurring melanomas in dogs as models for non-UV pathways of human melanomas.

Spontaneously occurring melanomas are frequent in dogs. They appear at the same localizations as in humans, i.e.
