Bio-mechanical effects of femoral neck system versus cannulated screws on treating young patients with Pauwels type III femoral neck fractures: a finite element analysis

open access: yesBMC Musculoskeletal Disorders
Introduction As a novel internal fixation for femoral neck fractures, the femoral neck system has some advantages for young Pauwels type III femoral neck fractures without clear biomechanical effects and mechanisms. Thus, the objection of the study is to

Sea Cucumber‐Inspired Double‐Network Biopolymer Hydrogels for Programmable Soft Machines

open access: yesAdvanced Science, EarlyView.
Inspired by the mutable dermis of sea cucumbers, the collagen‐alginate double‐network elastomeric (CoDE) hydrogel achieves programmable, recoverable, and functional mechanical behavior. The CoDE hydrogel mimics the mutable stiffness of the sea cucumber dermis through a densified collagen cryogel scaffold that is secondarily reinforced by a dissipative,

β‐Adducin Restrains PLA2G4A‐Dependent Lysosomal Membrane Permeabilization and Neuronal Death in Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
This study identifies β‐adducin as a regulator of lysosomal integrity in ischemic neurons. Ischemia‐associated FTO loss increases m6A modification and destabilizes Add2 mRNA, reducing β‐adducin expression and promoting PLA2G4A accumulation at lysosomes.

Long‐Term Expandable Periosteal Organoids Reconstruct a Functional Regenerative Niche That Support Hematopoietic Stem Cell Maintenance and Bone Repair

open access: yesAdvanced Science, EarlyView.
A robust periosteal organoid system enables long‐term expansion while preserving native cellular heterogeneity. These organoids recapitulate functional niche environments, support hematopoietic stem cell maintenance, and attenuate aging‐associated decline ex vivo.

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 ...

From Artificial to Embodied and Physical Intelligence in Smart Manufacturing

open access: yesAdvanced Science, EarlyView.
Smart manufacturing is reframed through complementary artificial, embodied, and physical intelligence, spanning computational reasoning, perception‐action coupling, and material‐level adaptation. Their integration across design, fabrication, operation, and maintenance reveals how intelligence can be co‐designed across algorithms, embodied agents, and ...

Lithium‐Doped Hydroxyapatite Nanowires Rejuvenate Senescent Macrophages Via the Lysosome‐Dependent Ferroptosis Axis to Promote Aged Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Li‐nHAP+GelMA promotes mandibular bone regeneration in aged mice by remodeling the senescent immune microenvironment. Local delivery of Li‐nHAP restores lysosomal homeostasis in senescent macrophages, reduces intracellular labile Fe2+ accumulation, ROS production, and lipid peroxidation, thereby suppressing macrophage ferroptosis and senescence ...
