Retention of locally injected human iPS cell-derived cardiomyocytes into the myocardium using hydrolyzed gelatin
Published 2025-02-01“…Using both ex vivo and in vivo rat models, we investigated how varying HG concentrations affect the retention of solution and diffusion within the myocardium. In ex vivo static rat hearts, 10% HG minimized leakage but allowed significant diffusion. …”

Verification of Interaction Between Cl<sup>−</sup> Erosion and Carbonation in Marine Concrete
Published 2025-01-01“…This study reveals that (1) Cl<sup>−</sup> erosion hinders concrete carbonation as NaCl crystals and Friedel’s salt in the pores limit CO<sub>2</sub> penetration, with this effect intensifying at higher artificial seawater concentrations; (2) carbonation has a dual impact on Cl<sup>−</sup> erosion: in fully carbonated areas, carbonation products block pores and restrict Cl<sup>−</sup> diffusion, while at the interface between carbonated and non-carbonated zones, carbonation depletes Ca(OH)<sub>2</sub>, reducing Cl<sup>−</sup> binding capacity, increasing free Cl<sup>−</sup> content, and promoting Cl<sup>−</sup> diffusion.…”
