Ultrasound‐Responsive 4D Bioscaffold for Synergistic Sonopiezoelectric‐Gaseous Osteosarcoma Therapy and Enhanced Bone Regeneration

Advanced Science, EarlyView.
An acoustic‐responsive therapeutic platform for synergistic sonopiezoelectric‐gaseous osteosarcoma therapy and bone regeneration is fabricated through the joint loading of few‐layer black phosphorus nanosheets and S‐Nitroso‐L‐glutathione onto the 3D‐printed bioactive glass scaffolds.

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.

Robust Controlled Degradation of Enzyme Loaded PCL‐Based Fibrous Scaffolds Toward Scarless Skin Tissue Regeneration

Advanced Science, EarlyView.
A novel biodegradable wound dressing (E‐PCLs) based on polycaprolactone (PCL) and an enzyme complex (RHP‐BCL) is developed using a fiber microfluidic electrospinning technique. The dressing achieves complete degradation within 14 days, eliminates microplastic residues, and promotes scar‐free healing (99% in 21 days).

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii

Advanced Science, EarlyView.
Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.

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 ...

Quantification and Visualization of Fungal Degradation of Polyurethane Foam in Homes [PDF]

, 2020
People spend 90% of their time in the indoor environment including homes. Homes contain many exposures that can cause harm to human health, and one harmful exposure potentially comes from the degradation of polyurethanes.

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.

Hierarchical Plant Protein Microcapsules for Hydrophilic and Hydrophobic Cargo Molecules [PDF]

arXiv
Microscale hydrogels comprised of macromolecular networks have increasingly been used for applications involving cell encapsulation, tissue engineering and for the storage and release of active cargo molecules. However, the majority of such microgels are formed from nonbiodegradable synthetic polymers, involving harmful solvents, or using animal ...
