Universal Solvent Escape Strategies for Efficient Curing of Hydrogen‐Bond‐Rich 3D Printing Inks

open access: yesAdvanced Science, EarlyView.
This study developed a new 3D printing method for hydrogen‐bonded polymers by combining solvent replacement, nanoparticles, and optimized printing paths. This allows fast, precise scaffold fabrication. The scaffolds can be easily customized and release therapeutic agents slowly through protonation, enabling personalized bone, blood vessel, and nerve ...

Modified Fuzzy Logic System Based Predictive Model for Cortical Bone Drilling Temperature

open access: yesFuzzy Information and Engineering
Bone drilling is a widely used procedure in fracture treatments. During drilling, the temperature in the host site increases and leads to permanent thermal damage called osteonecrosis, which increases the healing time and weakens the implant stability ...

Ultrasonic Assisted Drilling of Bone

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2008
Ultrasonic Assisted Drilling (USD) is new technique to drill difficult to machine materials. In this method, tool or workpiece vibrates with amplitude of few microns in addition to conventional drill bite rotation. In this experimental research, the bone was drilled both conventionally and using UAD, then the thrust was measured in two methods at feed ...

Early Radial Extracorporeal Shockwave Stimulation on Proximal Tibial Circular Osteotomy Site Enhanced Heterotopic Skin Wound Healing via Small Extracellular Vesicles

open access: yesAdvanced Science, EarlyView.
A schematic diagram of the mechanism where small extracellular vesicles mediate the enhancement of heterotopic wound healing by radial extracorporeal shockwave stimulation at a proximal tibial osteotomy site. ABSTRACT Wound healing represents a complex biological process necessitating innovative therapeutic approaches, particularly for chronic wounds ...

Investigation into bone drilling and thermal bone necrosis [PDF]

open access: yesAdvances in production engineering & management, 2007
This paper studies the problem and presents the results of different possibilities of avoiding the occurrence of thermal bone necrosis. In fact, in case of fracture of human bones, the best way to better and faster knitting is when a traumatologist fixes the fractured bone ends by drilling and setting the immobilization plates by screws. Because of the

A DNA Tetrahedron Delivery Asiatic Acid to Reprogram Mitochondrial Metabolism for Promoting Bone Regeneration via STAT3 Phosphorylation

open access: yesAdvanced Science, EarlyView.
A hyaluronic acid methacrylate (HAMA) hydrogel incorporating DNA tetrahedrons loaded with Asiatic acid (TDN@AA) was developed. HM‐TDN@AA promotes angiogenesis of endothelial cells (ECs), inhibits osteoclastogenesis from bone marrow–derived macrophages (BMDMs), and enhances osteogenesis of mesenchymal stem cells (MSCs) via STAT3‐mediated mitochondrial ...

Dual‐Anchored Clickable Peptide via SPAAC for Gelatinase‐Responsive Antibacterial and Osteogenic Functions on Titanium Implants

open access: yesAdvanced Science, EarlyView.
To address the infection‐associated orthopedic implant failures, this study presents a gelatinase‐responsive antibacterial titanium implant (Ti‐Dual) featuring a dual‐anchored fusion peptide containing antibacterial (HHC36) and osteogenic (RGD) domains connected by a cleavable GPLGV linker.

H2S‐Releasing Aspirin Nanoparticles Alleviate Endometriosis and Associated Anxiety

open access: yesAdvanced Science, EarlyView.
Albumin nanoparticles loaded with an H2S‐releasing aspirin derivative (ACS14) hitchhiking neutrophils after intraperitoneal injection and preferentially accumulate in endometriosis lesions in mice. The treatment suppresses lesion growth by regulating PI3K/Akt and reduces inflammation by inhibiting NF‐κB.

CGRP Enhances the Regeneration of Bone Defects by Regulating Bone Marrow Mesenchymal Stem Cells Through Promoting ANGPTL4 Secretion by Bone Blood Vessels

open access: yesAdvanced Science, EarlyView.
CGRP interacts with HMEC‐1 by binding to surface receptors, influencing the downstream FAK/AKT/VEGF signaling pathway, and promoting the secretion of ANGPTL4 from vascular endothelial cells into the bone microenvironment. This, in turn, regulates the differentiation of BMSCs into osteoblasts, thus promoting bone formation. ABSTRACT Bone angiogenesis is
