Journal ArticleDOI
Osteocyte-Intrinsic TGF-β Signaling Regulates Bone Quality through Perilacunar/Canalicular Remodeling.
Neha S. Dole,Courtney M. Mazur,Claire Acevedo,Justin P. Lopez,Justin P. Lopez,David A. Monteiro,David A. Monteiro,Tristan W. Fowler,Bernd Gludovatz,Flynn Walsh,Jenna N. Regan,Sara A. Messina,Daniel S. Evans,Thomas Lang,Bin Zhang,Robert O. Ritchie,Robert O. Ritchie,Khalid S. Mohammad,Tamara Alliston,Tamara Alliston +19 more
TL;DR: It is shown that TGF-β regulates PLR in a cell-intrinsic manner to control bone quality and emphasized that osteocytes are key in executing the biological control of bone quality through PLR, thereby highlighting the fundamental role of osteocyte-mediatedPLR in bone homeostasis and fragility.
Journal ArticleDOI
Bioinspired nacre-like alumina with a bulk-metallic glass-forming alloy as a compliant phase.
Amy Wat,Je In Lee,Chae Woo Ryu,Bernd Gludovatz,Jinyeon Kim,Jinyeon Kim,Antoni P. Tomsia,Takehiko Ishikawa,Julianna Schmitz,Andreas J. Meyer,Markus Alfreider,Daniel Kiener,Eun Soo Park,Robert O. Ritchie,Robert O. Ritchie +14 more
TL;DR: The authors use the reactive wetting of a zirconium-based bulk metallic glass to successfully infiltrate a porous alumina and create a composite with improved flexural strength and fracture toughness.
Journal ArticleDOI
Alendronate treatment alters bone tissues at multiple structural levels in healthy canine cortical bone.
Claire Acevedo,Hrishikesh Bale,Bernd Gludovatz,Amy Wat,Simon Y. Tang,Mingyue Wang,Björn Busse,Elizabeth A. Zimmermann,Eric Schaible,Matthew R. Allen,David B. Burr,Robert O. Ritchie,Robert O. Ritchie +12 more
TL;DR: It is hypothesized that the reduced plasticity associated with bisphosphonate treatments may induce an increase in microcrack accumulation and growth under cyclic daily loadings, and potentially increase the susceptibility of cortical bone to atypical (fatigue-like) fractures.
Journal ArticleDOI
Ab initio modeling of the energy landscape for screw dislocations in body-centered cubic high-entropy alloys
TL;DR: In this article, the authors investigated the distribution of dislocation core properties in MoNbTaW RHEAs alloys, and how they are influenced by chemical short-range order (SRO) in these multiple principal element alloys on dislocation mobility.
Journal ArticleDOI
Hyperelastic phase-field fracture mechanics modeling of the toughening induced by Bouligand structures in natural materials
TL;DR: In this paper, an orientation-dependent, hyperelastic, phase-field fracture mechanics method was developed to examine the relative fracture toughness of elasmoid fish scales comprising single vs. double-twisted Bouligand structures of fibrils.
