Optical Windows for Transcranial Brain Imaging in Living Mice: Skull Thinning, Clearing, and Beyond

Advanced Science, EarlyView.
Longitudinal, noninvasive in vivo imaging is crucial for studying brain physiology. Advances in transcranial optical windows and multiphoton microscopy have improved imaging depth, but their performance often deteriorates over time. This work investigated various transcranial window approaches and found that skull regrowth limits image quality.

Outcomes of cement beads and cement spacers in the treatment of bone defects associated with post-traumatic osteomyelitis

BMC Musculoskeletal Disorders, 2017
Background Cement spacers (Masquelet technique) have traditionally been used for the treatment of segmental bone defects. However, no reports have used cement spacers for the treatment of small/partial segmental bone defects associated with osteomyelitis

Effect of bone cement augmentation with different configurations of the dual locking plate for femoral allograft fixation: finite element analysis and biomechanical study

Journal of Orthopaedic Surgery and Research, 2023
Aims Implant failure in allograft reconstruction is one of the most common problems after treating a large bone defect for a primary bone tumor. The study aimed to investigate the effect of bone cement augmentation with different configurations of dual ...

Identification of an Osteochondral Erosion Process in Gout Driven by Fibrinogen‐Integrin Activation and Local MSU Crystallization

Advanced Science, EarlyView.
Cartilage injury promotes local fibrinogen deposition, which accelerates monosodium urate crystallization and activates integrin‐mediated matrix‐degradation. This self‐amplifying cycle drives gout‐related cartilage erosion. Disrupting fibrinogen deposition or restoring the cartilage barrier could interrupt this vicious cycle.

Neuropeptide Y—Graphene Oxide Complexes Inhibit Amygdala NPY‐Receptor Expressing Glutamatergic Pathways and Selectively Remove Aversive Memory In Vivo

Advanced Science, EarlyView.
A graphene oxide nanocarrier presents neuropeptide Y specifically to NPY receptor‐expressing pathways in the amygdala, whose activation selectively suppresses aversive memory formation, without modulating anxiety responses. This circuit‐restricted drug release strategy may impact future design of neuropsychiatric therapies with limited off‐target ...

A Comparison of Percutaneous Kyphoplasty with High-Viscosity and Low-Viscosity Bone Cement for Treatment of Osteoporotic Vertebral Compression Fractures: A Retrospective Study

Geriatric Orthopaedic Surgery & Rehabilitation, 2022
Background Osteoporotic vertebral compression fracture (OVCF) has become a health issue of worldwide concern. Percutaneous kyphoplasty (PKP) is one of the main surgical methods for OVCFs. This study aimed to evaluate and compare the clinical efficacy and

Self‐Assembly of Organic–Inorganic Copolymers Toward Bio‐Inspired Cementitious Composites

Advanced Science, EarlyView.
Organic–inorganic copolymerization of calcium silicate hydrate and thioctic acid produces a self‐organized nanocomposite inspired by the disordered collagen–mineral architecture of trabecular bone. The resulting material combines a compressive strength above 300 MPa with intrinsic physical reprocessibility, retaining over 80% of its strength and energy

Biomechanical Effects of Cement Distribution in the Fractured Area on Symptomatic Osteoporotic Vertebral Compression Fractures: A Three-Dimensional Finite Element Analysis

Global Spine Journal, 2015
Introduction According to some clinical studies, insufficient cement distribution in fractured area and asymmetrical cement distribution around fractured area were thought to be the reasons for unrelieved pain and recollapse after percutaneous vertebral ...
