A circumferentially flanged tibial tray minimizes bone-tray shear micromotion [PDF]

open access: yes, 2005
Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening.

Engineered Microvascular Model of the Blood–Brain–Tumor Barrier Reveals Endothelial Remodeling in Diffuse Midline Glioma

open access: yesAdvanced Healthcare Materials, EarlyView.
We developed a patient‐derived, functional microfluidic model of the diffuse midline glioma (DMG) blood–brain–tumor barrier (BBTB) comprised of endothelial cells, astrocytes, pericytes, and tumor cells. The system forms perfusable microvasculature, reveals the BBTB retains vascular integrity, identifies DMG‐specific transcriptomic changes distinct from

The use of structural and non structural bone grafts and substitutes in osteotomies and arthrodesis of the hindfoot and ankle [PDF]

open access: yes, 2011
Introduction: Hindfoot fusions and osteotomies implicate the decision whether to use an autologous bone graft or an osteoconductive or –inductive substitute material in order to promote bony union and/or to support the correction of an additional ...

Dynamic Loading Regulates Meniscus‐Like Matrix Production in Human Mesenchymal Stromal Cell‐Seeded PET Scaffolds

open access: yesAdvanced Healthcare Materials, EarlyView.
Dynamic compression enhances mesenchymal stromal cell proliferation in nonwoven PET scaffolds under chondrogenic differentiation conditions and triggers mechanosensitive transcriptional programs associated with extracellular matrix remodeling. These findings highlight the potential of mechanically stimulated PET scaffolds as a promising platform for ...

Expression patterns of chondrocyte genes cloned by differential display in tibial dyschondroplasia [PDF]

open access: yes, 2000
Tibial dyschondroplasia (TD) appears to involve a failure of the growth plate chondrocytes within growing long bones to differentiate fully to the hypertrophic stage, resulting in a mass of prehypertrophic chondrocytes which form the avascular TD lesion.

Targeting CD300a Signaling With a Phosphatidylserine‐Presenting Hydrogel Rescues Macrophage Dysfunction and Accelerates Diabetic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
Schematic illustration of the proposed mechanism: PEG/RGD‐PSLs mimic apoptotic cells to engage PS receptors (notably CD300a), transducing an inhibitory signal that suppresses the MyD88/NF‐κB pathway, leading to global anti‐inflammatory and pro‐reparative effects.

Clinical factors associated with trabecular bone score.

open access: yes, 2013
Dual-energy X-ray absorptiometry (DXA) measurement of bone mineral density (BMD) is the reference standard for diagnosing osteoporosis but does not directly reflect deterioration in bone microarchitecture.

Computational modelling and optimization of porous plates for mandibular fracture fixation accounting for bone healing

open access: yesMaterials & Design
Appropriate fixation is critical for mandibular fracture healing, as it enhances biomechanical stability. This study assessed the impact of fixation techniques and bone plate designs on angle mandible fractures, aiming to optimize healing processes and ...

Plate dynamics, mantle structure and tectonic evolution of the Caribbean region [PDF]

open access: yes, 2013
The northeastern Caribbean exhibits high deformation and is fragmented by several faults into smaller tectonic blocks. One of these faults was the site of the catastrophic 12th of January 2010 earthquake. In this thesis I aim to constrain the main forces
