Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

open access: yesAdvanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Semantic decomposition Network with Contrastive and Structural Constraints for Dental Plaque Segmentation [PDF]

open access: yesarXiv, 2022
Segmenting dental plaque from images of medical reagent staining provides valuable information for diagnosis and the determination of follow-up treatment plan. However, accurate dental plaque segmentation is a challenging task that requires identifying teeth and dental plaque subjected to semantic-blur regions (i.e., confused boundaries in border ...

Stable, Easy‐to‐Handle, Fully Autologous Electrospun Polymer‐Peptide Skin Equivalent for Severe Burn Injuries

open access: yesAdvanced Functional Materials, EarlyView.
A bioengineered skin equivalent composed of electrospun poly(ε‐caprolactone) (PCL) and the bioactive peptide Fmoc‐FRGD is developed for severe burn treatment. This scaffold promotes full‐thickness skin regeneration by supporting cellular adhesion and integration. In‐vitro and in‐vivo studies show enhanced mechanical stability, accelerated wound closure,

Use of Irreversible Hydrocolloid to Blockout Interproximal Spaces for an Easy Impression Taking

open access: yesFrontiers in Dentistry, 2009
Making impression to obtain an accurate working cast needs to use accurate impression materials such as polyether. On the other hand, polyether cannot be used easily in places with undercut such as excessive interproximal spaces and under the pontics of ...

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels

open access: yesAdvanced Functional Materials, EarlyView.
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

An Investigation of the Dimensional Stability of Dental Alginates [PDF]

open access: yes, 2006
Dimensional stability was defined by Nicholls (1977) as “the ability (of a material) to maintain accuracy over time”, and the result of loss of accuracy, “distortion”, as “the relative movement of a single point, or group of points, away from some ...
