WebCyclic mechanical strain was applied during 15 and 60 minutes, respectively. While both, healthy and degenerative tendon cells, responded to strain by an increased proliferation, the cell viability of the degenerative cells was significantly lower compared the healthy cells. WebJul 13, 2005 · We showed that cyclic mechanical strain induced HASM proliferation and migration in a MMP-dependent manner. Strain-induced MMP release was mediated via …
WebJan 22, 2024 · Physiological cyclic mechanical stretch (10% linear strain, 0.2 Hz) significantly impaired the alveolar epithelial wound healing process relative to culture in static conditions. This impairment could be partially ameliorated by administration of rhHGF. This proof-of-concept study provides a way to study of more complex interactions, such … WebThe void compression stage causes porous cement mortar to present special mechanical properties. In order to study the compaction behavior and the damage evolution of the porous material, cement mortar specimens with an average porosity of 26.8% were created and cyclic uniaxial compression tests were carried out. The irreversible strain …
