Fluid Shear‐Controlled Pro/Anti‐Inflammatory Osteomodulatory Construct for Drug‐Free Immune Activation Through Cationic Ion Channel Activation

open access: yesAdvanced Healthcare Materials, EarlyView.
A 3D‐printed PCL scaffold coated with Arginine was laminated with electrospun polyvinyl alcohol (PVA) nanofibers containing cationic cellulose nanocrystals (PVA@cCNC). This created nanoisland‐like regions of aligned and random cCNC‐rich fibers. The composite scaffold, under fluid shear stimulation, modulated macrophage polarization from M1 to M2 ...

Comparison of a reverse-transverse cross pin technique with a same side cross pin type II external skeletal fixator in 89 dogs [PDF]

open access: yes, 2015
The objective of this study was to determine whether a novel reverse-transverse cross pin insertion technique could increase the stability of type II external skeletal fixators (ESF) in dogs compared with an alternate, same side cross pin ESF.

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

A profiling analysis of contributions of cigarette smoking, dietary calcium intakes, and physical activity to fragility fracture in the elderly [PDF]

open access: yes, 2018
Fragility fracture and bone mineral density (BMD) are influenced by common and modifiable lifestyle factors. In this study, we sought to define the contribution of lifestyle factors to fracture risk by using a profiling approach.

Si Inhibited Osteoclastogenesis: The Role of Fe and the Fenton Reaction

open access: yesAdvanced Healthcare Materials, EarlyView.
Silicate (Si) inhibition of osteoclastogenesis, is mediated by Fe. Si chemical interactions with Fe inhibit the Fenton reaction and intercellular ROS availability. This reduction in ROS availability inhibits osteoclastogenesis. The addition of Fe, in Si‐inhibited osteoclast cultures, restores the Fenton reaction, and osteoclastogenesis.

Vibration‐Mediated Recovery of Irradiated Osteocytes and Their Regulatory Role in Breast Cancer Bone Metastasis

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiotherapy damages bone and disrupts osteocyte function, yet mechanically mediated protection remains largely unexplored. This study demonstrates that low‐magnitude, high‐frequency (LMHF) vibration mitigates irradiated osteocyte apoptosis, restores their ability to regulate breast cancer extravasation, and acts synergistically with radiotherapy to ...

3D‐Printed Multidimensional Bionic Mg‐MC/PLGA Composite for Tailored Repair of Segmental Long Bone Defects

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops 3D‐printed Mg‐MC/PLGA scaffolds with varying Mg concentrations (0–20%). The 5% Mg scaffold shows optimal cytocompatibility, osteogenic activity in vitro, and significantly enhances bone regeneration in rabbits, improving bone volume and mechanical strength.
