Comparison of analgesic efficacy and safety between liposomal bupivacaine and ropivacaine for paravertebral block in patients undergoing thoracoscopic lung tumor surgery: a prospective double-blind randomized controlled trial

Background Thoracoscopic lung tumor surgery is associated with significant postoperative pain. While liposomal bupivacaine (LB) provides prolonged analgesia, its higher cost and extended duration profile have not been directly compared with ropivacaine, a commonly used long‑acting local anesthetic in paravertebral bloc...

Effect of Initial Grain Size on High‐Temperature Tensile Deformation and Microstructural Evolution of GH2907 Alloy

To investigate the effect of grain size on the tensile deformation behavior and dynamic softening mechanisms of GH2907 alloy at 500 and 600 °C, fine‐grained (FG) and coarse‐grained (CG) specimens were prepared via solution treatment. High‐temperature tensile tests were performed at 500 and 600 °C, combined with mechani...
