Biocompatibility and inflammatory response of silver tungstate, silver molybdate, and silver vanadate microcrystals.

Silver tungstate (α-AgWO), silver molybdate (β-AgMoO), and silver vanadate (α-AgVO) microcrystals have shown interesting antimicrobial properties. However, their biocompatibility is not yet fully understood. Cytotoxicity and the inflammatory response of silver-containing microcrystals were analyzed in THP-1 and THP-1 differentiated as macrophage-like cells, with the alamarBlue™ assay, flow cytometry, confocal microscopy, and ELISA.

Inactivation of SARS-CoV-2 by a chitosan/α-AgWO composite generated by femtosecond laser irradiation.

In the current COVID-19 pandemic, the next generation of innovative materials with enhanced anti-SARS-CoV-2 activity is urgently needed to prevent the spread of this virus within the community. Herein, we report the synthesis of chitosan/α-AgWO composites synthetized by femtosecond laser irradiation. The antimicrobial activity against Escherichia coli, Methicilin-susceptible Staphylococcus aureus (MSSA), and Candida albicans was determined by estimating the minimum inhibitory concentration (MIC) and minimal bactericidal/fungicidal concentration (MBC/MFC).

Antifungal Activity and Biocompatibility of α-AgVO, α-AgWO, and β-AgMoO Using a Three-Dimensional Coculture Model of the Oral Mucosa.

Fungal infections have become a major concern in the medical community, especially those caused by spp. Within this species, stands out for being an opportunistic commensal fungus that can cause superficial and invasive infections. Current antifungal therapy involves the local and/or systemic use of drugs such as azoles, polyenes, and echinocandins.

Antifungal activity and biocompatibility of α-AgVO microcrystals: A promising material against oral Candida disease.

The number of studies on microcrystals containing silver has increased in recent decades. Among the silver-containing microcrystals, α-AgVO has gained prominence owing to its polymorphism that allows it to exert interesting antimicrobial activity against pathogenic microorganisms. The aim of this study was to evaluate the antifungal activity and cytotoxicity of three different α-AgVO microcrystals when in solution.

Mechanism of Antibacterial Activity via Morphology Change of α-AgVO: Theoretical and Experimental Insights.

The electronic configuration, morphology, optical features, and antibacterial activity of metastable α-AgVO crystals have been discussed by a conciliation and association of the results acquired by experimental procedures and first-principles calculations. The α-AgVO powders were synthesized using a coprecipitation method at 10, 20, and 30 °C. By using a Wulff construction for all relevant low-index surfaces [(100), (010), (001), (110), (011), (101), and (111)], the fine-tuning of the desired morphologies can be achieved by controlling the values of the surface energies, thereby lending a microscopic understanding to the experimental results.

Effects of Image Compression on Linear Measurements of Digital Panoramic Radiographs.

This study aimed to evaluate the accuracy of panoramic radiographs obtained by digital system based on charge coupled device (CCD) and a phosphor storage plate (PSP) system with two different file formats, JPEG irreversible type and BMP. Linear measurements of artificial bony defects were made in dry mandibles with a digital caliper. Measures of digital panoramic radiographs were taken in ImageJ(r) software.
