Phagocytosis of apoptotic cells and cellular debris is a critical process of maintaining tissue and immune homeostasis. Defects in the phagocytosis process cause autoimmunity and degenerative diseases. Phagocytosis ligands or "eat-me" signals control the initiation of the process by linking apoptotic cells to receptors on phagocyte surface and triggering(More)
BACKGROUND Augmented reality (AR) fuses computer-generated images of preoperative imaging data with real-time views of the surgical field. Scopis Hybrid Navigation (Scopis GmbH, Berlin, Germany) is a surgical navigation system with AR capabilities for endoscopic sinus surgery (ESS).

Hemostasis is an important concept in pediatric otolaryngologic surgery. This article details the considerations the otolaryngologist should take when it comes to clinical evaluation and surgical technique. It begins with the preoperative evaluation, and evolves into the use of different mechanical and chemical methods of operative hemostasis. We detail use(More)
BACKGROUND Microsensor navigation has the potential to aid balloon sinus ostial dilation by providing real-time tracking of balloon devices within the complex anatomy of the sinonasal cavities. OBJECTIVE This feasibility study evaluated the incorporation of a new microsensor technology into a flexible guidewire for use with current instruments in balloon(More)
Phospholipid scramblase 1 (PLSCR1) is a multiply palmitoylated, endofacial membrane protein originally identified based on its capacity to promote accelerated transbilayer phospholipid movement in response to Ca(2+). Recent evidence suggests that this protein also participates in cell response to various growth factors and cytokines, influencing myeloid(More)
