Atherosclerosis is a complex progressive disease involving intertwined biological mechanisms. We aimed to identify miRNA expression dynamics at the early stages of atherosclerosis using a large swine model (Wisconsin Miniature Swine, WMS). A total of 18 female pigs; 9 familial hypercholesterolemic (WMS-FH) and 9 normal control swine (WMS-N) were studied. miRNA sequencing was performed on plasma cell-free RNA at 3, 6, and 9 months of age. RT-qPCR validated DE miRNAs in a new cohort of animals (n = 30) with both sexes. Gene ontology and mRNA targets for DE miRNAs were identified. In vivo multimodality imaging and histopathology were performed to document the presence of atherosclerosis at termination. 20, 19, and 9 miRNAs were significantly DE between the groups at months 3, 6, and 9, respectively. Most DE miRNAs and their target genes are involved in human atherosclerosis development. Coronary atherosclerosis was documented in 7/9 WMS-FH pigs. Control animals had no lesions. miR-138, miR-152, miR-190a, and miR-196a showed a significant diagnostic power at month 3, whereas miR-486, miR-126-3p, miR-335, and miR-423-5p were of significant diagnostic power at month 9. In conclusion, specific DE miRNAs with significant discriminatory power may be promising biomarkers for the early detection of coronary atherosclerosis.

Background And Aim: Low birth weight and within-litter variations are major challenges in swine production, often exacerbated by highly prolific sow lines. Nutritional interventions such as amino acid and probiotic supplementation have shown promise, but their combined effects remain unexplored. This study aimed to evaluate the individual and interactive effects of QST 713 and L-arginine supplementation during late gestation on reproductive performance in sows.

Background And Aim: Primiparous sows are particularly vulnerable to prolonged weaning-to-service interval (WSI), which negatively impacts reproductive efficiency and farm profitability. This study aimed to identify critical risk factors associated with prolonged WSI (>6 days) in first-parity Landrace × Yorkshire sows raised under tropical conditions.
Materials And Methods: A retrospective cohort analysis was performed using production records from 3,222 sows on a commercial farm in Central Vietnam.

Background: In catheter-based radiofrequency ablation (RFA), energy is delivered to heterogeneous thin-walled tissues to induce therapeutic heating. Variations in electrical and mechanical properties of tissue contents have a great effect on outcomes.
Purpose: The objective of this study is to develop models that replicate tissue heterogeneity and visualize ablation zones for effective evaluation and optimization.

This study aimed to develop an acellular dermal matrix derived from tilapia skin and evaluate its potential as a bioscaffold for skin wound repair. Structural and compositional changes before and after decellularisation were assessed through histological staining, electron microscopy and immunological analysis. The matrix exhibited low immunogenicity, preserved extracellular matrix architecture and retained key bioactive components.

Objectives: Kidney transplant is a life-saving procedure for patients with end-stage renal disease. Success of kidney transplant is highly dependent on maintaining the integrity of the endothelium and its protective layer, the endothelial glycocalyx. Ischemia-reperfusion injury, a common challenge in kidney transplant, can disrupt the endothelial glycocalyx, leading to various post-transplant complications.
