Article Synopsis
- A study examined mesenteric lymph nodes and ileocecal valves from 105 goats (61 non-vaccinated, 44 vaccinated) with a history of paratuberculosis (PTB) to assess the presence of subclinical infections and lesions.
- Results revealed that 39% of the goats had gross PTB-compatible lesions, with a higher prevalence in non-vaccinated goats compared to vaccinated ones.
- The research highlighted the importance of using both histopathological assessments and laboratory techniques to accurately diagnose PTB, but calls for further research to improve sampling methods for subclinical cases in goats.
Article Synopsis
- The amygdala, a key brain structure involved in fear and anxiety responses, consists of various nuclei, including the central nucleus (CeA), which helps regulate stress-related hormones.
- Five dolphins from different species were studied to analyze the structure of the CeA using specific staining techniques.
- Findings revealed that the CeA in dolphins has a similar structure to that in primates, indicating potential parallels in emotional processing across species.
The hypothalamus is the body's control coordinating center. It is responsible for maintaining the body's homeostasis by directly influencing the autonomic nervous system or managing hormones. Beaked whales are the longest divers among cetaceans and their brains are rarely available for study.

From a database of 2526 tumours collected from 2003 to 2020, we conducted a longitudinal analysis of the main trends in diagnosis, age, multiplicity and anatomical distribution as well as a case-control study comparing these cases with the contemporaneous canine population of the Canary Archipelago to analyse breed distribution. In line with former studies, we found histiocytomas mostly affect young dogs (2, IQR 1-5) and mast cell tumours affect middle-to-old dogs (8, IQR 6-10) with grade 1 affecting at younger ages (6.

Acute systemic gas embolism in these whales was reported together with enigmatic cystic liver lesions (CLL), characterized by intrahepatic encapsulated gas-filled cysts, tentatively interpreted as "gas-bubble" lesions in various other cetacean species. Here we provide a pathologic reinterpretation of CLL in odontocetes.
