Myocardial sarcomere dynamics during isometric contraction.

The Journal of Physiology, 1975
1. Sarcomere lengths were measured during rest and throughout the time course of isometric contractions in thin, isolated rat papillary muscles using light diffraction techniques. 2. Shortening of the sarcomere length occurred upon contraction at all muscle lengths, averaging 7% at optimal length and more at shorter lengths.

Immunomodulatory Hydrogel Coating with SeNPs and Lithium Silicate Synergistically Promotes Osseointegration and Prevents Infection on Titanium Implants

Advanced Science, EarlyView.
This study introduces a multifunctional hydrogel coating (Lap‐CMCSMA/GelMA@SeNPs) that scavenges ROS, modulates immune responses, and shows strong antibacterial activity. It effectively restores the peri‐implant microenvironment. The coating exhibits excellent biocompatibility and promotes osteogenic differentiation.
