Ocular Health of Octodon degus as a Clinical Marker for Age-Related and Age-Independent Neurodegeneration [PDF]
Frontiers in Integrative Neuroscience, 2021 The aging process and age-related diseases such as Alzheimer’s disease (AD), are very heterogeneous and multifactorial, making it challenging to diagnose the disease based solely on genetic, behavioral tests, or clinical history.

Branching patterns of the adrenal arteries in the degu (Octodon degus). [PDF]
J Vet Med Sci, 2021 The degu has drawn increasing attention for use as an experimental animal in stress response studies due to its physiological features, such as diurnality and seasonal breeding, which differ from conventional laboratory rodents. Stress response is elicited by steroid hormones secreted by the adrenal gland, whose functions are controlled by pituitary ...

Disseminated histiocytic sarcoma in a degu (Octodon degus). [PDF]
J Vet Med SciA 7-year-and-8-month-old, male degu (Octodon degus) with anorexia, depression, and labored breathing was found to have a thoracic effusion and enlargement of the right testis on radiographic examination. Despite treatment, the animal died. At necropsy, hepatomegaly, splenomegaly, and multifocal nodules on the intestinal serosa and mesentery were ...

Music preference in degus (Octodon degus): Analysis with Chilean folk music.
Animal Behavior and Cognition, 2018 Most nonhuman animals do not show selective preference for types of music, but researchers have typically employed only Western classical music in such studies. Thus, there has been bias in music choice.
