Summary: The performance of polyvinylidene fluoride (PVDF)-based piezoelectric nanogenerator (PENG) is influenced by the addition of nanofillers, which modify the piezoelectric coefficient and relative permittivity of PVDF. In this study, the role of external force shapes, piezoelectric coefficient, and relative permittivity on the open-circuit voltage and short-circuit current of PVDF nanocomposite film-based PENG was analyzed using COMSOL MULTIPHYSICS 5.5. The results showed that a square-shaped force resulted in the maximum output performance of the PENG.

Summary: Cell clusters from primary tumors migrate collectively and are more effective in forming distant metastases compared to single cancer cells. Stromal cells in the clusters, such as mesenchymal stromal cells (MSCs) or cancer-associated fibroblasts (CAFs), facilitate metastatic dissemination by transporting low-motile cancer cells in a Rac-dependent manner. Co-traveling stromal cells play an active role in the collective migration of tumor cell clusters.

Summary: This study provides insights at the single-cell level on the distinct patterns of endothelial cells and smooth muscle cells (SMCs) responses to vascular injury. Less than 30% of SMCs responded to the injury, forming proinflammatory SMCs and stress-responsive SMCs clusters. Proinflammatory SMCs were enriched with inflammatory markers while stress-responsive SMCs overexpressed heat shock proteins. The interaction between macrophages and proinflammatory SMCs was found to be the major cell-cell communication among all cell types in the injured arteries.
