During routine health examinations, an abnormal growth was detected in the oral cavity of a male giant panda. A malignant tumor, osteosarcoma, was diagnosed through CT (computed tomography) scans and pathological examination of biopsy samples. After two attempts at "tumor reduction surgery" with no improvement, the condition stabilized following particle implantation and arterial infusion interventional therapy. The following year, a CT scan revealed a highly similar mass in the left lumbar muscle, which showed no improvement despite chemotherapy, leading to death 1 month later. Post-mortem examination and tissue pathological diagnosis confirmed osteosarcoma characteristics in the facial, lumbar, and liver masses. The giant panda was diagnosed with osteosarcoma with liver metastasis based on integrated pathological and gross anatomical observations. This case represents the first report of osteosarcoma with liver metastasis in a giant panda, providing valuable data and references for future clinical diagnosis and treatment of tumors in giant pandas.

To explore the cause of this apparently counterintuitive preference, we used spatial and data analysis tools to analyze the spatial composition of the daily activity zones, the relative quantity of traces, the trace density, and the slope supply of the reserves. We found that the slope composition around gentle slopes and steep slopes is similar, with more traces clustered around gentle slopes.

Background: Maintaining good oral and gut health is essential for the wellbeing of animals, and fungi are key components of the oral and gut microbiota. This study aims to explore the diversity and seasonal dynamics of oral and gut fungal communities in captive giant pandas, with a focus on their potential functional roles in health and digestion.
Methods: In the study, we collected saliva and fecal samples from 60 captive giant pandas were collected in different seasons, oral and gut fungi were analyzed using internal transcribed spacer (ITS) amplicon sequencing.

Background: Musk, secreted by the musk gland of adult male musk-secreting mammals, holds significant pharmaceutical and cosmetic potential. However, understanding the molecular mechanisms of musk secretion remains limited, largely due to the lack of comprehensive multiomics analyses and available platforms for relevant species, such as muskrat (Ondatra zibethicus Linnaeus) and Chinese forest musk deer (Moschus berezovskii Flerov).
Results: We generated chromosome-level genome assemblies for the 2 species of muskrat (Ondatra zibethicus Linnaeus) and musk deer (Moschus berezovskii Flerov), along with 168 transcriptomes from various muskrat tissues.
