Enhanced Selenium Supplement Extends Lifespan and Delays Multi‐Organs Aging by Regulating the Sik1 Pathway Through Maintaining Calcium Homeostasis

open access: yesAdvanced Science, EarlyView.
Aging involves physiological decline and heightened disease susceptibility, necessitating effective interventions. Redox‐responsive selenium‐loaded nanoparticles (SeMSNs) are developed, which delay cellular senescence by reducing oxidative stress and senescence markers (p16/p21). In aged mice, SeMSNs extend lifespan, improve organ function, and restore

Nonunion of coronal shear fracture of femoral condyle

open access: yesChinese Journal of Traumatology, 2011
【Abstract】Isolated coronal fractures of femoral condyle are rare in adults and nonunion of Hoffa fracture is reported only a few times in the literature. We analyzed six cases of nonunion of Hoffa fractures over a period of three years.

Super Time‐Resolved Tomography

open access: yesAdvanced Science, EarlyView.
A super time‐resolved tomography (STRT) approach is presented to reconstruct 4D X‐ray movies with an order‐of‐magnitude improvement in temporal resolution without sacrificing spatial resolution. By leveraging a physics‐informed deep learning algorithm that shares spatiotemporal features, STRT achieves high‐fidelity 3D reconstructions from sparse‐view ...

Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts

open access: yesAdvanced Science, EarlyView.
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

A rare case of bicondylar Hoffa fracture associated with ipsilateral tibial spine avulsion and extensor mechanism disruption

open access: yesChinese Journal of Traumatology, 2012
【Abstract】Intra-articular coronal fractures (Hoffas fractures) of distal femur are rare. Although bicondylar involvement in these fractures has been reported in the litera- ture in association with high velocity traumata, the occurrence of these ...

Injectable and In Situ Hydration‐Reinforced Hybrid Bone Cements for Accelerated Bone Regeneration

open access: yesAdvanced Science, EarlyView.
To enable minimally invasive bone defect repair, an injectable and hydration‐reinforced bone cement (L‐PEGS/CPC) is designed through biomimetic reconstruction. The hydrophilic L‐PEGS organic phase provides abundant nucleation sites, synergizing with its porous architecture to accelerate CPC hydration, thereby endowing the composite with exceptional ...
