Background: Microbial and fungal growth, particularly , is a major issue with the usage of maxillofacial silicone material, which can lead to chronic infection, inflammation, and silicone material degradation, for which the development of an antimicrobial silicone elastomer has become crucial.
Methodology: This study was designed to determine the efficacy of adding chitosan nanoparticles (1.5%, 3%, and 5% by weight) to silicone matrix on antifungal activity. Eighty specimens were fabricated with varying concentrations of chitosan and separated into four groups [C1 (control), C2 (1.5%wt chitosan reinforced silicone), C3 (3%wt chitosan/silicone), and C4 (5%wt chitosan/silicone)]. An antifungal test was conducted on each group.
Results: The inhibition zone was concentration dependent in antifungal tests; as the concentration increased, the inhibition zone grew as well.
Conclusion: Improvement in the antifungal activity of silicone was demonstrated when chitosan nanoparticles were incorporated.

Seborrheic dermatitis (SD) is a chronic inflammatory skin disorder most commonly affecting areas rich in sebaceous glands, such as the scalp, face, axilla, and groin. Several factors can precipitate SD development, such as colonization of Malassezia, sebocyte activity, impaired immunity, and environmental influences. Topical antifungals, corticosteroids, and calcineurin inhibitors are the current mainstay treatment of SD.

Citrus fruits, known for their vibrant flavours and health benefits, are susceptible to fungal attacks, particularly from toxigenic fungi, which pose a significant pre- and post-harvest hazard. However, aromatic oils and their nanoparticles may effectively address this issue. Marjoram and fennel oils, alongside their nanoparticles, were extracted, and their aromatic constituents and antimicrobial activities were evaluated.

Reptiles may act as reservoirs or spreaders of potential pathogenic microorganisms including Candida yeasts. While the epidemiology of yeast species has been thoroughly studied, the virulence profile of isolated species is not well investigated. Therefore, this study aimed to assess the haemolytic, phospholipase, lipase activities and biofilm formation of yeasts isolated from the cloacal swabs of venomous snakes from Marrakech, Morocco (Group I, n = 40) and from non-venomous snakes from Cocullo, Italy (Group II, n = 32).

Insulin resistance (IR) disrupts hepatic glucose metabolism and mitochondrial function, which contributes to metabolic disorders. The present study examined the effects of tomatine on glucose metabolism in high-glucose-induced IR hepatocytes and explored its underlying mechanisms using AML12 and HepG2 cell models. The results showed that tomatine did not exhibit cytotoxic effects.
