Multi‐Responsive PAA/PNIPAM Semi‐IPN Hydrogel Properties Controlled by PAA Topology

Macromolecular Rapid Communications, Volume 47, Issue 15, 4 August 2026.
Polymer topology governs hydrogel behavior in semi‐interpenetrating networks. Cyclic poly(acrylic acid) enables controlled pH‐responsive swelling, improved stability, and enhanced deformability compared to linear analogues, while linear systems show higher strength during thermal de‐swelling.

3D Liver Fibrosis Models in Lab: A Novel Modality for Drug Screening

Pharmacology Research &Perspectives, Volume 14, Issue 4, August 2026.
ABSTRACT Liver fibrosis is the common consequence of liver injury caused by a variety of chronic liver disorders. This condition leads to the development of more severe complications, particularly cirrhosis and hepatocellular carcinoma. Despite abundant studies, the fundamental cell and molecular mechanisms of liver fibrosis are still unknown.
