Grading of oligodendroglioma in dogs based on magnetic resonance imaging.

Background: Oligodendroglioma (OG) accounts for 22% of primary brain tumors in dogs. Oligodendroglioma in dogs is graded as low-grade (II) or high-grade (III), based on the presence of microvascular proliferation and necrosis.

Objective: To investigate if magnetic resonance imaging (MRI) features differ between OG II and III in dogs.

HEALTH ASSESSMENT OF CAPTIVE AND FREE-LIVING EUROPEAN POND TURTLES () IN SWITZERLAND.

The highly endangered European pond turtle () was reintroduced in Switzerland in 2010. Up until 2019, no routine medical examinations have been carried out prior to its release or during recapture events. The aim of this study was to assess the health status of captive and free-living populations in Switzerland, taking into account the most important and frequently occurring health threats to freshwater turtles.
