Penetrating captive bolt (PCB) is widely used for stunning and on-farm dispatch of livestock, yet its efficacy can vary, with the potential for animal welfare compromise. This study investigated the pathophysiology of PCB-induced trauma in horned and polled sheep (), focusing on factors contributing to incomplete concussion. Thirty-seven ( = 18 horned Scottish blackface and = 19 polled North Country mule) mature ewes (aged 4-10 years) were shot with PCB with varying cartridge power and PCB modifications, followed by clinical assessment and post-mortem analysis using magnetic resonance imagining (MRI) and gross pathology.

However, there are no collections derived from South American BC patients. Since ethnicity significantly impacts clinical outcomes, it is necessary to develop PDX models from different lineages.

- Large-scale studies are essential to investigate the gut microbiota's complex relationships with health and disease, and tissue preservation methods need evaluation for feasibility in such research.
- Biopsies from 20 adults with inflammatory bowel disease were preserved using three methods: flash freezing, nucleic acid preservative reagents, and formalin fixation with paraffin embedding (FFPE), with microbiota analyzed using sequencing.
- Results showed that while preservative reagents can serve as viable alternatives to flash freezing, FFPE samples exhibited distinct community structures, highlighting the potential utility of historical samples despite differences in microbial profiles.
Overcoming luminal breast cancer (BrCa) progression remains a critical challenge for improved overall patient survival. RUNX2 has emerged as a protein related to aggressiveness in triple-negative BrCa, however its role in luminal tumors remains elusive. We have previously shown that active FGFR2 (FGFR2-CA) contributes to increased tumor growth and that RUNX2 expression was high in hormone-independent mouse mammary carcinomas.

Despite OP having pathophysiological features distinct from lung cancer, the two may be confused based on similar clinical, radiological, and histopathological findings. This distinction is further clouded by the dynamic nature of these diseases.
