A Rigid–Foldable Kirigami‐Inspired Metamorphic Mechanism With Programmable Motion Modes and Self‐Locking

open access: yesAdvanced Science, EarlyView.
Geometric constraint reconfiguration enables a rigid–foldable kirigami‐inspired mechanism to switch between twisting, directional translation, and self‐locking states. By encoding multifunctionality directly into its architecture, the mechanism achieves multimodal motion and passive locking without reassembly, providing a compact platform for adaptive ...

An in-vitro biomechanical comparison of annular ligament repair and reconstructions to restore radial head stability in anterior Monteggia fractures

open access: yesJSES International
Background: Persistent or recurrent instability of the radial head (RH) remains a challenge in treating anterior Monteggia fractures despite anatomic restoration of the ulna.

Osseoperceptive EMG Feedback Improves Grasp Force Control in Myoelectric Prosthetic Hands

open access: yesAdvanced Science, EarlyView.
Osseoperception is explored as a non‐invasive pathway for delivering sensory feedback in myoelectric prosthetic control. By encoding the user's electromyographic (EMG) signal through bone‐conducted stimulation, this approach enables predictive grasp force regulation.

Identifying diagnostic criteria for upper- and lower-limb\ud lymphoedema [PDF]

open access: yes, 2016
BACKGROUND\ud \ud Bioimpedance spectroscopy (BIS) assesses resistance (impedance) to the flow of an electrical current. Through the measurement of impedance to currents at low (R0) and high (Rinf) frequencies, extracellular fluid (ECF) and total body ...

TECTB Variants Reveal Tectorial Membrane Vulnerability in Dominant Non‐Syndromic Hearing Loss

open access: yesAdvanced Science, EarlyView.
TECTB is a non‐collagenous protein of the tectorial membrane – an extracellular matrix of the cochlea. This study identifies dominant missense variants in TECTB linked to human hereditary deafness in two unrelated families. Genetically engineered mice homozygous for one of the variants are profoundly deaf, whereas heterozygous mice have normal hearing ...

An Injectable Metal‐Drug Supramolecular Condensate Enables Radiosensitization and Systemic Antitumor Immunity for Post‐Surgical Osteosarcoma Therapy

open access: yesAdvanced Science, EarlyView.
This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

Bone Marrow Macrophage STING Signaling is a Direct Nexus Linking Marrow Adipose Expansion to NAD+ Depletion and Osteogenic Decline in Skeletal Aging

open access: yesAdvanced Science, EarlyView.
This study reveals that during skeletal aging, bone marrow adipocyte‐derived sDPP4 primes STING signaling in macrophages. In combination with mitochondrial DNA, this signaling activates CD38 and depletes local NAD+/NMN, thereby impairing osteogenesis.

Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

open access: yesAdvanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...
