This study aims to evaluate two of the most commonly used products, the collagen-based patch (Hemopatch) and the micropolysaccharide microspheres powder (Perclot), in the context of stab liver injury in pigs. The objectives of this study were to assess blood loss at various time intervals up to 24 h, survival rates, and mean arterial pressure. The research involved 18 Large-White swine.

This study investigated the effects of cholic acid (CA) on steroid hormone synthesis and follicular development in mouse ovaries and the regulatory mechanism of CA on the expression of steroidogenesis-related genes in granulosa cells. The mice were divided into control and CA groups, and serum and ovarian samples were collected after 1, 2, and 4 months of treatment, respectively. The results showed that CA treatment for 1, 2, and 4 months reduced ovarian weights, disrupted the estrous cycle, decreased the number of antral follicles and corpora lutea, and lowered the serum levels of progesterone and estradiol.

Pre-established anaesthetic protocols in animal models might unexpectedly interfere with the main outcome of scientific projects and therefore they need to account for the specific research goals. We aimed to optimize the anaesthetic protocol and animal handling strategies in a diabetes-related-study exemplifying how the anaesthetic approach must be adjusted for individual research targets. Aachen minipigs were used as a model to test long-lasting skin glucose sensors for diabetic human patients.

Porcine epidemic diarrhea virus (PEDV), Transmissible gastroenteritis virus (TGEV), Porcine deltacoronavirus (PDCoV) and Swine acute diarrhea syndrome coronavirus (SADS-CoV) rank among the most frequently encountered swine enteric coronaviruses (SECoVs), leading to substantial economic losses to the swine industry. The availability of a rapid and highly sensitive detection method proves beneficial for the monitoring and surveillance of SECoVs. Based on the N genes of four distinct SECoVs, a novel detection method was developed in this study by combining recombinant enzyme polymerase isothermal amplification (RPA) with clustered regularly interspaced short palindromic repeats (CRISPR)-associated proteins (Cas) 12a.

Respiratory disease (RD) is a worldwide leading threat to the pig industry, but there is still limited understanding of the pathogens associated with swine RD. In this study, we conducted a nationwide genomic surveillance on identifying viruses, bacteria, and antimicrobial resistance genes (ARGs) from the lungs of pigs with RD in China. By performing metatranscriptomic sequencing combined with metagenomic sequencing, we identified 21 viral species belonging to 12 viral families.
