Enhancing bone tissue engineering using iron nanoparticles and magnetic fields: A focus on cytomechanics and angiogenesis in the chicken egg chorioallantoic membrane model.

Aim: To evaluate the potential of iron nanoparticles (FeNPs) in conjunction with magnetic fields (MFs) to enhance osteoblast cytomechanics, promote cell homing, bone development activity, and antibacterial capabilities, and to assess their in vivo angiogenic viability using the chicken egg chorioallantoic membrane (CAM) model.

Settings And Design: Experimental study conducted in a laboratory setting to investigate the effects of FeNPs and MFs on osteoblast cells and angiogenesis using a custom titanium (Ti) substrate coated with FeNPs.

Materials And Methods: A custom titanium (Ti) was coated with FeNPs.

Modified technique for retaining silicone auricular prosthesis: a case report.

Prosthetic rehabilitation of auricular defects can be a demanding procedure due to a broad variety of clinical presentations and a wide array of treatment options. The retention of auricular prostheses is a major factor influencing the successful outcome of rehabilitative treatment following cancer surgery or trauma. Auricular prostheses have been retained by methods including implants, adhesives and spectacle frames but the choice of repair ultimately depends on patient factors, amount of soft tissue loss, and location of the auricular defect.
