Selenium's potential against candidiasisEvaluating the anti- effects of selenium nanoparticles impregnated in acrylic resins: An in vitro study.
We focused on the effectiveness of selenium nanoparticles (SeNPs) incorporated into acrylic resins to combat candidiasis, specifically in the context of denture-induced stomatitis. Current treatments often come with side effects and can lead to drug resistance, making this research particularly relevant.
Our study involved formulating acrylic resins with varying concentrations of SeNPs—0.2, 2, and 10 g/mL—and testing them against clinical isolates. We determined the minimum inhibitory concentration (MIC) and developed fungal biofilms on acrylic samples, assessing the level of biofilm through various methods, including scanning electron microscopy (SEM).
We found that the MIC for SeNPs stood at 25%, with the highest antifungal activity observed at a concentration of 10%. The optical density measurements indicated that the 10% SeNPs group effectively reduced biofilm formation compared to lower concentrations. SEM analysis confirmed significant damage to the fungal cell walls, aligning with our findings of decreased colonization.
These results suggest that selenium nanoparticles can be a promising alternative treatment for candidiasis, particularly for those wearing dentures. Their ability to inhibit fungal growth demonstrates SeNPs' potential in addressing oral health issues connected to candidiasis.

Selenium's antifungal potential explored(MeOPhSe)2, a synthetic organic selenium compound, inhibits virulence factors of Candida krusei: Adherence to cervical epithelial cells and biofilm formation.
We delved into the potential of a synthetic organic selenium compound, known as p,p'-methoxyl-diphenyl diselenide, or (MeOPhSe), to combat candidiasis, particularly focusing on its effects on Candida krusei. This research is important because Candida species can lead to both mild and serious infections, and finding effective treatments is crucial.
Our study demonstrated that (MeOPhSe) is non-toxic to human cells, such as cervical epithelial and fibroblastic cells, and has a notable antifungal effect. We observed that it inhibited the growth of C. krusei in a dose-dependent manner, altering its growth pattern and extending the length of its lag phase. Most significantly, we found that this compound reduced the ability of both C. krusei and C. albicans to adhere to human cells, a critical step in the infection process.
The reductions we measured were substantial: C. krusei adherence dropped by 37.24%, while C. albicans showed a 32.84% reduction, both being statistically significant. Interestingly, both species responded similarly to (MeOPhSe), highlighting its potential as a broad-spectrum antifungal agent against various Candida infections.
Overall, our findings suggest that (MeOPhSe) holds promise as an antifungal treatment targeting the virulence factors of different Candida species, paving the way for new treatment options in battling candidiasis.

Effective selenium delivery against candidiasisMucoadhesive gellan gum hydrogel containing diphenyl diselenide-loaded nanocapsules presents improved anti-candida action in a mouse model of vulvovaginal candidiasis.
We aimed to evaluate how diphenyl diselenide, encapsulated in poly(ε-caprolactone) nanocapsules, affects candidiasis treatment. By preparing a suspension of these nanocapsules and creating a gellan gum hydrogel, we studied the in vitro antifungal properties and their effectiveness in a mouse model of vulvovaginal candidiasis.
The study involved testing both the encapsulated form of diphenyl diselenide and a version without the nanocapsules against several Candida strains. Interestingly, we found that the nanocapsules demonstrated equal or improved antifungal activity compared to the free compound.
In our model, female Swiss mice were infected with Candida albicans and then treated with the hydrogels containing either the encapsulated form or the free compound. We monitored the fungal burden after treatment and found that the nano-encapsulated version exhibited superior antifungal action, indicating that the encapsulation effectively preserves and enhances the treatment properties of diphenyl diselenide.
Overall, our findings suggest that this innovative, nano-based hydrogel formulation holds promise as a significant advancement in treating vulvovaginal candidiasis.

Selenium nanoparticles inhibit candidiasisInhibition of Candida albicans biofilm by pure selenium nanoparticles synthesized by pulsed laser ablation in liquids.
We explored the effects of selenium nanoparticles on Candida albicans, particularly focusing on their ability to inhibit biofilm formation. The nanoparticles were created using a cutting-edge technique known as femtosecond pulsed laser ablation in de-ionized water, ensuring they were free from contaminants.
Our observations revealed that these pure selenium nanoparticles could effectively attach to the biofilm of Candida albicans. Once adhered, the nanoparticles penetrated the pathogen and began to disrupt its cellular structure by substituting sulfur. Remarkably, we achieved a 50% reduction in biofilm formation at a low concentration of just 25 parts per million (ppm).
Furthermore, our analysis highlighted two important factors affecting the effectiveness of the selenium treatment: the crystallinity and size of the particles. This study suggests that pure selenium nanoparticles hold promising potential for advancing future treatments for candidiasis by targeting harmful biofilm formations.

Selenium miconazole improves candidiasis treatmentLead optimization generates selenium-containing miconazole CYP51 inhibitors with improved pharmacological profile for the treatment of fungal infections.
We examined the effectiveness of new selenium-containing miconazole derivatives against candidiasis, specifically focusing on how these compounds can tackle Candida albicans infections. In our previous research, we identified compound A03, which showed significant antifungal activity, but also had concerning side effects like hemolysis and cytotoxicity.
To improve upon this, we optimized our compounds, ultimately leading us to compound B17. Not only did B17 maintain impressive antifungal potency, but it also showcased a much better pharmacological profile. With less tendency to be metabolized and diminished toxic effects, B17 offers a promising option for treating resistant Candida infections.
Additionally, we found that B17 effectively disrupted important fungal processes, such as ergosterol biosynthesis and biofilm formation, which are crucial for fungal survival. Our tests even showed that B17 has promising efficacy in live models, which is an encouraging step forward. Overall, these selenium-infused miconazole compounds hold great potential as innovative treatments for fungal infections, particularly candidiasis.
