Composite resins for posterior tooth restorations have become a viable alternative to dental amalgam. Failures sometimes cannot be easily explained, and we hypothesize that a genetic component may influence longevity of restorations. We aimed to determine if there is any evidence for a difference in the performance of amalgams versus composite resin in extensive posterior restorations. We also ...
Endothelial cells (ECs) and vascular smooth muscle cells (VSMCs) have been shown to communicate with each other via cytokine signaling during neovascularization. In this study, we investigated the effect of platelet-derived growth factor (PDGF), a cytokine released from tumors and ECs, on vascular endothelial growth factor (VEGF) expression in human VSMCs and underlying signal transduction path...
Galactic winds play a key role in regulating the evolution of galaxies over cosmic time. In recent years, rays (CR) formation galactic wind has increasingly gained attention. Therefore, we use radio continuum data to analyse ray transport edge-on galaxies. Data from LOFAR Two-metre Sky Survey (LoTSS) release 2 at 144 MHz (HBA) and reprocessed VLA 1.6 GHz (L-band) Continuum Halos Nearby Galaxies...
