Controversies in spine research: Organ culture versus in vivo models for studies of the intervertebral disc

JOR SPINE, Volume 5, Issue 4, December 2022., 2022
Abstract Intervertebral disc degeneration is a common cause of low back pain, the leading cause of disability worldwide. Appropriate preclinical models for intervertebral disc research are essential to achieving a better understanding of underlying pathophysiology and for the development, evaluation, and translation of more effective treatments.

A Bio‐Responsive Hydrogel with Spatially Heterogeneous Structure for Treating Infectious Tissue Injuries

Advanced Science, EarlyView.
The hydrogel incorporates Ag⁺‐loaded Preyssler‐type polyoxometalates (POMs) that release Ag⁺ ions in response to endogenous Na⁺ ions, ensuring controlled antibacterial activity. The spatially heterogeneous structure, created through dual‐channel fiber stacking and in situ cross‐linking, enhances structural integrity and promotes tissue regeneration ...

Learning Disease State from Noisy Ordinal Disease Progression Labels [PDF]

arXiv
Learning from noisy ordinal labels is a key challenge in medical imaging. In this work, we ask whether ordinal disease progression labels (better, worse, or stable) can be used to learn a representation allowing to classify disease state. For neovascular age-related macular degeneration (nAMD), we cast the problem of modeling disease progression ...

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.

Reinforcing Stromal Cell Spheroid Through Red‐Light Preconditioning for Advanced Vascularization

Advanced Science, EarlyView.
This study presents a novel approach to enhance stromal cell therapy for myocardial infarction by combining OLED‐based photobiomodulation (OPBM) preconditioning with 3D spheroid culture of hADSCs. The engineered spheroids improve angiogenesis, arterialization, and cardiac function in vivo, offering a next‐generation therapeutic strategy to overcome ...

AuCu@CuO2 Aerogels with H2O2/O2 Self‐Supplying and Quadruple Enzyme‐Like Activity for MRSA‐Infected Diabetic Wound Management

Advanced Science, EarlyView.
The AuCu@CuO2 aerogels demonstrate favorable photothermal properties, four types of enzyme‐like activities, and H2O2/O2 self‐supplying to modulate the complex microenvironment of MRSA‐infected diabetic wounds. The results indicate that the AuCu@CuO2 aerogel can be activated by the microenvironment of diabetic wound infection, alleviating inflammation ...

Sulfated Galactans from Gracilaria fisheri with Supplementation of Octanoyl Promote Wound Healing Activity In Vitro and In Vivo

Macromolecular Bioscience, Volume 22, Issue 12, December 2022., 2022
Gracilaria fisheri sulfated galactans are degraded, supplemented with octanoyl and sulfate groups, and characterized by GPC, FTIR and NMR. Octanoyl sulfated galactans show superior wound healing activity both in fibroblasts culture and in rats. The possible wound healing mechanism of octanoyl sulfated galactans is through the regulation of proteins and

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.
