Modulation of fracture healing by the transient accumulation of senescent cells

eLife, 2021
Senescent cells have detrimental effects across tissues with aging but may have beneficial effects on tissue repair, specifically on skin wound healing. However, the potential role of senescent cells in fracture healing has not been defined.

Self-healing slip pulses and the friction of gelatin gels [PDF]

, 2003
We present an extensive experimental study and scaling analysis of friction of gelatin gels on glass. At low driving velocities, sliding occurs via propagation of periodic self-healing slip pulses whose velocity is limited by collective diffusion of the ...

Vibration therapy as an intervention for enhancing trochanteric hip fracture healing in elderly patients: a randomized double-blinded, placebo-controlled clinical trial

Trials, 2021
Background There are more than 300,000 hip fractures yearly in the USA with mortality rates of 20% within 1 year. The treatment of osteoporotic fractures is a major challenge as bone quality is poor, and healing is expected to delay due to the impaired ...

Development of an ischemic fracture healing model in mice

Acta Orthopaedica, 2022
Background and purpose: In fracture healing, ischemia caused by vascular injuries, chronic vascular diseases, and metabolic comorbidities is one of the major risk factors for delayed union and non-union formation.

Multiple targets identified with genome wide profiling of small RNA and mRNA expression are linked to fracture healing in mice

Bone Reports, 2021
Long-bone fracture is a common injury and its healing process at the fracture site involves several overlapping phases, including inflammation, migration of mesenchymal progenitors into the fracture site, endochondral ossification, angiogenesis and ...

In vivo measurement of bending stiffness in fracture healing [PDF]

, 2003
Background Measurement of the bending stiffness a healing fracture represents a valid variable in the assessment of fracture healing. However, currently available methods typically have high measurement errors, even for mild pin loosening.

Dnmt3b ablation impairs fracture repair through upregulation of Notch pathway [PDF]

, 2020
We previously established that DNA methyltransferase 3b (Dnmt3b) is the sole Dnmt responsive to fracture repair and that Dnmt3b expression is induced in progenitor cells during fracture repair.

Characterization of the microstructural properties that are predictive of regain in strength in phosphate-deficient mice [PDF]

, 2016
Fracture healing occurs in a discrete set of steps, which recapitulates embryonic endochondral bone formation. Pathophysiologies of the fracture healing that prolong the fracture repair or result in non-union may be associated with either environmental ...

The local and systemic effects of immune function on fracture healing

OTA International
. The immune system plays an integral role in the regulation of cellular processes responsible for fracture healing. Local and systemic influences on fracture healing correlate in many ways with fracture-related outcomes, including soft tissue healing ...
