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

open access: yesAdvanced 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

Peptide nucleic acid (PNA) conformation and polymorphism in PNA-DNA and PNA-RNA hybrids. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1993
Two hydrogen-bonding motifs have been proposed to account for the extraordinary stability of polyamide "peptide" nucleic acid (PNA) hybrids with nucleic acids. These interresidue- and intraresidue-hydrogen-bond motifs were investigated by molecular mechanics calculations. Energy-minimized structures of Watson-Crick base-paired decameric duplexes of PNA
