Tuning micropillar cavity birefringence by laser induced surface defects [PDF]

, 2009
We demonstrate a technique to tune the optical properties of micropillar cavities by creating small defects on the sample surface near the cavity region with an intense focused laser beam.

Multi‐Responsive Dendrimer‐Hyaluronic Acid Hydrogel With Lubricating and Immunoregulatory Functions for Synergistic Osteoarthritis Therapy

Advanced Functional Materials, EarlyView.
A hydrogel with dynamic cross‐links was formed by cross‐linking hyaluronic acid with curcumin‐preloaded, phenylboronic acid‐modified poly(amidoamine) dendrimers. This hydrogel exhibited excellent injectability and self‐healing ability, enabling controlled Cur release in response to low pH, high reactive oxygen species (ROS) generation, or mechanical ...

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

Advanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

Characterization of an Injectable Poly(vinyl alcohol)‐gelatin Hydrogel for Growth Factor Delivery in an Orthopedic Application

Advanced Healthcare Materials, EarlyView.
This work introduces photo‐crosslinkable tyraminated poly(vinyl alcohol)‐gelatin (PVA‐GT) hydrogels as tunable injectable platforms for tissue engineering and growth factor delivery applications. This schematic illustrates the two developed hydrogel formulations and the experimental workflow used to evaluate their physico‐chemical properties in vitro ...

USE OF NASOLABIAL FLAP FOR RECONSTRUCTION OF THE SOFT TISSUES OVER THE ALVEOLAR RIDGE AFTER TRAUMA ON THE MANDIBLE: A CASE REPORT [PDF]

Journal of IMAB
Nasolabial flap technique (NLF) is the one of the oldest methods for reconstructing orofacial soft tissue defects. It is recognized as a simple, effective, and relatively safe method, with a low risk of complications.

Fabricating optical fibre-top cantilevers for temperature sensing [PDF]

, 2014
In this paper, we propose techniques to fabricate micro-cantilevers onto the end of standard single mode optical fibres using a combination of picosecond laser machining and focused ion beam milling techniques and demonstrate their use as temperature ...

Hollow-point ammunition and handguns: The potential for large temporary cavities

Injury Extra, 2008
In the civilian setting, gunshot wounds are usually secondary to handguns. Wound ballistics for handgun bullets are notable for low velocities and low kinetic energy; as a result, these bullets are thought to only injure tissues that are directly in their path. This bullet tract is called the permanent cavity. In contrast, high velocity rifles can also

Non-Ergodic Nuclear Depolarization in Nano-Cavities

, 2003
Recently, it has been observed that the effective dipolar interactions between nuclear spins of spin-carrying molecules of a gas in a closed nano-cavities are independent of the spacing between all spins.

Small Extracellular Vesicles from Neural Cells: Physiological and Pathological Roles, and Potential in Neurodegenerative Therapy

Advanced Healthcare Materials, EarlyView.
Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...
