Bone matrix material properties on the micro- and nanoscale

, 2012
The evaluation of fracture risk in osteoporotic patients, which is still mostly based on bone mineral density (BMD) measurements, constitutes a major clinical challenge.

Low Hemoglobin Is Associated With Low Bone Mineral Density and High Risk of Bone Fracture in Male Adults: A Retrospective Medical Record Review Study

American Journal of Men's Health, 2019
The aim of this study was to examine the association between serum hemoglobin level, bone mineral density, and fracture risks based on the estimated score of the Fracture Risk Assessment Tool (FRAX) in Asian male adults.

Sustainable Fabrication of Tailored Bone Substitutes: From High‐Throughput Scaffold Manufacturing, Scaled‐Up HMSC Expansion to Dynamic Cultivation in a Perfusion Bioreactor

Advanced Science, EarlyView.
ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...

Experimental fracture resistance study for cracked bovine femur bone samples

Fracture and Structural Integrity, 2019
Crack growth and brittle fracture is one of the major failure modes in bone materials and therefore understanding the fracture behavior and affecting parameters on the crack growth resistance of bone is necessary for biomechanics researchers.

Monitoring Techniques of Bone Fracture Healing Using External Fixators

Engineering Transactions, 2015
Long bone fractures can be healed using external fixators – devices that stiffly fix the fractured fragments, attached to the bone by pins parallel to the bone frame.

Unraveling Bone‐Skin Crosstalk Enables miRNA Nanoformulation for Cutaneous Neurovascular Reconstruction in Diabetic Mice

Advanced Science, EarlyView.
This study unravels that bone fracture accelerates diabetic wound healing by releasing exosomal microRNA (miR‐130b‐3p). To mimic this bone‐skin crosstalk, we engineered a self‐assembling agomir‐130b‐3p nanocomplex. Delivered via a photocrosslinkable hydrogel, this bio‐inspired therapy provides sustained localized agomir release.

Bound Water as a Reinforcing Element for Ultra‐Strong Polyacrylamide

Advanced Science, EarlyView.
Rather than acting as a conventional plasticizer, bound water serves as a reinforcing element in polyacrylamide by constructing strong PAM–water–PAM hydrogen‐bond networks. This water‐mediated architecture delivers ultra‐high mechanical strength and exceptional flame resistance, redefining the role of water in polymer reinforcement.
