Ultrasound‐Triggered Nanocomposite “Lever” Hydrogels with a Full Repair System Accelerates Diabetic Foot Ulcer Repair

Advanced Science, EarlyView.
Ultrasound (US)‐treated nanocomposite ‘lever’ hydrogels reprogrammed wound reactive oxygen species (ROS) levels and promoted wound healing in infected diabetic foot ulcers. Abstract Diabetic foot ulcers (DFUs) are a complex mixture of neuropathy, peripheral arterial disease, and infection, where excessive reactive oxygen species (ROS) exacerbates ...

Injectable and Sprayable Thermoresponsive Hydrogel with Fouling‐Resistance as an Effective Barrier to Prevent Postoperative Cardiac Adhesions

Advanced Science, EarlyView.
Postoperative cardiac adhesions lead to numerous difficulties in reoperation procedures. Here, a thermo‐responsive in situ formed hydrogel is shown to can reliably cover the wounds after a convenient spraying or injection and significantly reduce adhesion formation in primary and recurrent cardiac injury adhesion models.

The Role of MCPIP1 in Macrophage Polarization and Cardiac Function Post‐Myocardial Infarction

Advanced Science, EarlyView.
Following myocardial infarction, MCPIP1 deficiency in macrophages triggers ferroptosis, driving proinflammatory M1 dominance over reparative M2 phenotypes. This imbalance amplifies splenic monocyte release and sustains cardiac inflammation. Concurrently, excessive inflammatory mediators and insufficient TGF‐β impair fibroblast activation, delaying ...

Polymer Brush‐Based Asymmetric Porous Patch with Excellent Anti‐Bacterial and Anti‐Contamination Properties Enables Infectious Abdominal Wall Defect Repair

Advanced Science, EarlyView.
A zwitterionic asymmetric patch is developed via self‐induced phase separation. The cationic layer exhibits anti‐bacterial efficacy and releases pro‐healing factor, while the zwitterionic hydrogel prevents contamination and visceral adhesion. The strong mechanical interlocking of two layers leads to a high and stable burst pressure tolerance.

Gas Bubbles from Biodegradable Magnesium Implants Convey Mechanical Cues and Promote Immune Cell Stimulation

Advanced Science, EarlyView.
Bubbles in soft tissue are the unavoidable consequence of magnesium implant degradation in patients, yet their biological significance remains unclear. Using advanced imaging and spatial transcriptomics, this study reveals a pronounced inflammatory and mechanical response near bubbles, contrasting with pro‐regenerative events closer to the implant ...

Intraoperative Fast Adaptive Focus Tracking Robotic OCT Enables Real‐Time Tumor Grading and Large‐Area Microvascular Imaging in Human Spinal Cord Surgery

Advanced Science, EarlyView.
The fast adaptive focus tracking robotic optical coherence tomography (FACT‐ROCT) offers real‐time, high‐resolution imaging of spinal cord tumors during surgery. By reducing motion artifacts with robotics and adaptive focal tracking, it accurately differentiates tumor grades using a novel attenuation coefficient marker and reveals critical ...

Intelligent Perioperative System: Towards Real-time Big Data Analytics in Surgery Risk Assessment [PDF]

arXiv, 2017
Surgery risk assessment is an effective tool for physicians to manage the treatment of patients, but most current research projects fall short in providing a comprehensive platform to evaluate the patients' surgery risk in terms of different complications.

Ultrasound‐Responsive Piezoelectric Membrane Promotes Osteoporotic Bone Regeneration via the “Two‐Way Regulation” Bone Homeostasis Strategy

Advanced Science, EarlyView.
Patients with osteoporosis face a higher risk of bone injury, mainly due to weakened osteogenic differentiation and bone formation, along with increased osteoclast differentiation and bone resorption activity, leading to bone homeostasis imbalance.
