Επισκόπηση Τεχνολογιών Radio Over Fiber (ROF)

, 2012
Το αντικείμενο της παρούσας εργασίας είναι η παρουσίαση τρόπων επικοινωνίας σε ασύρματα δίκτυα με τη χρήση οπτικών ινών. Συγκεκριμένα γίνεται αναφορά στην ευρέως διαδεδομένη τεχνική ROF (Radio Over Fiber) που μέρα με τη μέρα συγκεντρώνει όλο και περισσότερο το ενδιαφέρον της επιστημονικής κοινότητας καθώς προβάλλεται σαν λύση για την κάλυψη των ...

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

A Data Driven Review of In Vitro Electrical and Mechanical Stimulation for Post‐Acute Phase Wound Healing

Advanced Healthcare Materials, EarlyView.
This review examines how in vitro electrical and mechanical stimulation modulates wound healing in fibroblasts and keratinocytes. Analyzing over 560 experimental data points, we relate stimulation parameters to proliferation and migration outcomes, evaluate platform designs, and highlight the need for multi‐parameter optimization to advance targeted ...

Recapitulating Endochondral Ossification for Bone Repair: From Development to Engineering Strategy

Advanced Healthcare Materials, EarlyView.
This review summarizes the developmental basis of endochondral ossification (ECO) and its applications in bone tissue engineering (BTE). It first outlines the key biological processes and signaling pathways underlying ECO, then discusses biomaterial‐based engineering strategies derived from these principles, and finally highlights future directions for
