Objective: Compare the efficacy of canine serum, fresh frozen plasma (FFP), freeze-thaw-cycled plasma (FTCP), and Solcoseryl(™) at inhibiting matrix metalloproteinases (MMP) 2 and 9 in vitro.
Procedure: Matrix metalloproteinases 2 and 9 activity in the presence of serum, FFP, FTCP, or Solcoseryl(™) was assayed using a commercially available fluorogenic gelatinase activity kit.
Results: Matrix metalloproteinases 2 activity in the presence of serum, FFP, FTCP, and Solcoseryl(™) was 20.84%, 5.76%, 8.10%, and 83.03%, respectively of uninhibited MMP 2 activity. MMP 9 activity in the presence of serum, FFP, FTCP, and Solcoseryl(™) was 57.36%, 58.35%, 49.35%, and -8.69%, respectively of uninhibited MMP 9 activity.
Conclusion: Serum, FFP, and FTCP exhibit similar levels of MMP 2 and 9 inhibitions. Solcoseryl(™) causes minimal MMP 2 inhibition, but profound MMP 9 inhibition.

Mechanism of Radix Bupleuri and Hedysarum Multijugum Maxim drug pairs on liver fibrosis based on network pharmacology, bioinformatics and molecular dynamics simulation.

A number of studies demonstrate the therapeutic effectiveness of Radix Bupleuri (RB) and Hedysarum Multijugum Maxim (HMM) in treating liver fibrosis, but the exact molecular mechanisms remain unclear. This study aims to explore the mechanism of RB-HMM drug pairs in treating liver fibrosis by using network pharmacology, bioinformatics, molecular docking, molecular dynamics simulation technology and in vitro experiments. Totally, 155 intersection targets between RB-HMM and liver fibrosis were identified.

COPD occurrence in non-smokers with AAT deficiency (AATD) suggests inflammatory processes may contribute to COPD risk independently of smoking. We hypothesized that inflammatory protein biomarkers in non-AATD COPD are associated with moderate-to-severe COPD in AATD individuals, after accounting for clinical factors.

Oral submucous fibrosis (OSF) is a chronic, progressive, and fibrotic condition of the oral mucosa that carries an elevated risk of malignant transformation. We aimed to identify and validate novel genes associated with the regulation of epithelial-to-mesenchymal transition (EMT) in OSF. Genes regulating EMT were identified through differential gene expression analysis, using a LogFC threshold of -1 and + 1 and a padj value < 0.

Osteosarcoma is the most common primary bone cancer, accounting for approximately 5 % of new cancer cases globally. In contrast, breast cancer remains the most prevalent malignancy and a leading cause of cancer-related mortality among women. Given the limitations of current therapies, novel treatment strategies are urgently needed.

Background: Skin melanoma is a highly metastatic cancer with an increasing global incidence. Despite advancements in immunotherapy, new treatment strategies based on tumor biology are essential for improving outcomes and developing novel therapies. Autophagy plays a critical role in melanoma cell metabolism and affects the tumor microenvironment (TME).
