Establishment of a chronic aspiration pneumonia mouse model using oropharyngeal aspiration of food suspension

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Four aspiration methods (UV, IN, IT, and OA) were compared, and OA was identified as the most effective delivery technique. A chronic aspiration pneumonia model was then established through repeated OA of food suspension or gastric contents. Integrated analyses, including micro‐CT, histopathology, cytokine profiling, and RNA sequencing, revealed ...

The Effect of Silk on the Stabilization of Labile Enzyme Lipoxygenase

open access: yesAdvanced NanoBiomed Research, EarlyView.
Entrapping lipoxygenase within silk significantly extended its stability from under 24 h to 10 days. Variations in silk molecular weight and freeze‐drying conditions influenced silk properties and enzyme interactions. This stabilization is leveraged to develop a linoleic acid electrochemical biosensor, integrating lipoxygenase with horseradish ...

Artificial salivas for in vitro studies of dental materials

open access: yesJournal of Dentistry, 1997
An artificial saliva (AS) of defined composition is necessary for testing the performance of materials that serve in the mouth as natural saliva is too variable. The chemistry involved is critically important. Many AS recipes can be found in the literature, but the stability of tooth material, i.e.

Corrosion of dental alloys in artificial saliva with Streptococcus mutans

open access: yesPLoS ONE, 2017
A comparative study of the corrosion resistance of CoCr and NiCr alloys in artificial saliva (AS) containing tryptic soy broth (Solution 1) and Streptococcus mutans (S. mutans) species (Solution 2) was performed by electrochemical methods, including open

Engineering Tertiary Lymphoid Structures: Nanomedicine, Bioengineering, and Biomaterials for Precision Immunotherapy

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review explains how biomaterials and nanoparticles can be used to induce or modulate tertiary lymphoid structures (TLSs), which are ectopic immune hubs that form in nonlymphoid tissues during chronic disease and cancer. By comparing different methods, the article highlights design principles for modeling TLSs or recapitulating specific TLS ...

Shear bond strength after dentin bleaching with 10% carbamide peroxide agents Resistência ao cisalhamento da dentina após clareamento com peróxido de carbamida a 10%

open access: yesBrazilian Oral Research, 2004
This in vitro study evaluated the shear bond strength (SBS) of dentin treated with two 10% carbamide peroxide bleaching agents 15 days after bleaching and storage in artificial saliva. Dentin fragments were randomly divided into 3 groups (n = 20) for the

Electrochemical behavior of TiN, CrN and TiN/CrN nanostructured coatings on the nickel-chromium alloy used in dental fixed prosthesis

open access: yesJournal of Asian Ceramic Societies, 2020
The aim of this research is the evaluation of the influence of TiN, CrN and TiN/CrN nanostructured coatings on corrosion resistance of nickel-chromium dental alloy in artificial saliva environment with two pH levels (3.0 and 6.5).
