Assessment of liver fibrosis and associated risk factors in HIV-infected individuals using transient elastography and serum biomarkers

, 2012
Background: Liver fibrosis in human immunodeficiency virus (HIV)-infected individuals is mostly attributable to co-infection with hepatitis B or C. The impact of other risk factors, including prolonged exposure to combined antiretroviral therapy (cART ...

Compact Tabletop Magnetic Resonance Elastography for Mapping Soft Tissue Viscoelasticity

Advanced Science, EarlyView.
This work introduces a compact, low‐cost tabletop magnetic resonance elastography platform for high‐resolution viscoelastic mapping in soft‐tissue specimens. Using this method in human colorectal liver metastases, we demonstrate fully automated biomechanical profiling of treatment response and show that heterogeneity‐based metrics outperform ...

Stiffness‐Activated Stellate Cells Drive Pancreatic Cancer Liver Colonization via GMFG‐TNS4 Signaling

Advanced Science, EarlyView.
Fibrotic liver stiffness activates hepatic stellate cells through Piezo1‐dependent calcium influx and ER stress, promoting EV‐associated GMFG release. Delivered GMFG engages TNS4 in pancreatic cancer cells, triggering FAK/AKT signaling, adhesion, and fatty acid synthesis.

Ten Minutes of Passive Hip and Knee Joint Movement Reduces Stiffness Due to Osgood‐Schlatter Disease in the Rectus Femoris Muscle

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To investigate the acute effects of passive movement on rectus femoris (RF) stiffness, flexibility, and subjective knee joint pain in patients with Osgood‐Schlatter disease (OSD). Methods Patients with bilateral OSD at the orthopedic clinic between July 2023 and June 2025 were prospectively enrolled.
