Cytoplasmic and nuclear Survivin expression in healthy gastric mucosae of equids: A comparative study between horses, donkeys, and mules.

Background: Information regarding Survivin protein expression in the gastric mucosa of equids is scarce. This protein has been associated with functions related to modulating apoptosis and promoting mitosis in epithelial cells and is considered part of gastric cytoprotection mechanisms in humans and mice, maintaining mucosal integrity and regulating cellular renewal.

Aims/objectives: This study aimed to determine the expression of cytoplasmic and nuclear Survivin in gastric mucosae of equids (horses, donkeys, and mules).

Morphological description of the alimentary canal and adnexal glands in Amazilia tzacatl, Amazilia saucerottei, Amazilia amabilis and Anthrachotorax nigricollis species.

The hummingbird family (Trochilidae) includes the smallest and most metabolically active vertebrates. They have a high energy demand because of their extraordinarily high metabolic rates during hovering while looking for food. The morphology of the digestive apparatus is related to the feeding habits of the species.

Histopathological Results of Mouth Lesions in Dogs and Cats from Colombia.

Mouth-related neoplastic and non-neoplastic lesions are commonly found in dogs and cats, and their diagnosis and classification are important for treatment planning and prognosis. This retrospective study analyzed mouth-related lesions in dogs and cats between 2000-2019 from the animal pathology laboratory of the Universidad de Antioquia, Medellín, Colombia. A total of 640 mouth-related lesions affecting 572 dogs (89.
