Nitrogen‐Doped Ultrananocrystalline Diamond – Optoelectronic Biointerface for Wireless Neuronal Stimulation

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 9, April 4, 2025.
Researchers demonstrate a diamond‐based, wireless biointerface capable of generating safe capacitive current under pulsed light illumination in the visible and near‐infrared light region. This biointerface is long‐lasting and the first among diamond‐based electrodes capable of optically‐controlled, non‐genetic modulation of intracellular calcium ...

Dexamethasone Delivery via Amphiphilic, Low‐swelling Hydrogels Treats Postoperative Inflammation in Cervical Spine Applications

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
DexaPatch, an implantable, low‐swelling amphiphilic hydrogel system containing dexamethasone‐PLGA microparticles, is developed and characterized for sustained local steroid release to reduce postoperative inflammation in tight surgical spaces. DexaPatch significantly reduces postoperative edema and fibrosis in a rabbit model of anterior spinal surgery,

CircAars‐Engineered ADSCs Facilitate Maxillofacial Bone Defects Repair Via Synergistic Capability of Osteogenic Differentiation, Macrophage Polarization and Angiogenesis

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
Schematic representation of circAars‐engineered‐ADSCs incorporated into GelMA scaffolds for craniomaxillofacial bone regeneration. CircAars‐engineered ADSCs embedded in GelMA scaffolds enhance the repair of critical‐sized bone defects by binding miR‐128‐3p in the cytoplasm, thereby inhibiting its activity.

Bioprinting Perfusable and Vascularized Skeletal Muscle Flaps for the Treatment of Volumetric Muscle Loss

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 13, May 16, 2025.
Volumetric muscle loss (VML) due to trauma or surgery, often leads to physical impairments. Traditional treatments rely on autologous flaps, limited by muscle availability often leading to donor site morbidity. This study presents multimodal bioprinting as an innovative approach for fabricating vascularized muscle flaps with 3D‐printed macrovessels ...

Rod‐shaped Polymerized Salicylic Acid Particles Modulate Neutrophil Transendothelial Migration in Acute Inflammation

open access: yesAdvanced Healthcare Materials, EarlyView.
Rod‐shaped particles outperform spherical particles of the same volume in preventing neutrophil infiltration to inflamed areas, both in vitro and in vivo. This therapeutic effectiveness is attributed to better cell targeting and decreased cell motility, resulting from the geometry‐driven phagocytosis and inhibited actin polymerization.

Quinin as a Local Anesthetic.

open access: yesJournal of the American Medical Association, 1908
Fredonia, N. Y., Aug. 10, 1908. To the Editor: —Allow me to state that at the annual meeting of the Chautauqua County (N. Y.) Medical Society, held July 14, 1896, I reported that: "Quinin is a safe and efficient anesthetic when used hypodermatically and much safer than cocain." A report of the proceedings of that meeting in the Buffalo Medical ...

Organoid‐Like Neurovascular Spheroids Promote the Recovery of Hypoxic‐Ischemic Skin Flaps Through the Activation of Autophagy

open access: yesAdvanced Healthcare Materials, EarlyView.
Highly sprouting organoid‐like neurovascular spheroids (NVUs) are developed, featuring cell‐loaded poly‐3‐hydroxybutyrate 4‐hydroxybutyrate(P34HB) porous microsphere cores embedded within Gelatin Methacryloyl. NVUs formed complex vascular plexuses and secreted extracellular matrix in vitro, simulating autologous nerves and blood interaction.

A Dual‐Layer Hydrogel Barrier Integrating Bio‐Adhesive and Anti‐Adhesive Properties Prevents Postoperative Abdominal Adhesions

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 11, April 25, 2025.
A new dual‐layer hydrogel barrier for preventing postoperative abdominal adhesions is developed. The inner layer, consisting of polyethyleneimine (PEI) and thioctic acid (TA), enhanced adhesion to moist tissues. The outer layer combines zwitterionic, thermoresponsive hyaluronic acid with anti‐inflammatory epigallocatechin gallate (EGCG) and forms a ...

Imine Crosslinked, Injectable, and Self‐Healing Fucoidan Hydrogel with Immunomodulatory Properties

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops an injectable fucoidan‐based hydrogel with tunable properties for tissue engineering. By oxidizing fucoidan (OFu) to introduce aldehydes, imine crosslinks are formed with amine‐containing polymers, enabling self‐healing, injectability, and long‐term stability (≥28 days). The OFu‐gelatin hydrogel demonstrated biocompatibility, immune‐
