Photodynamic therapy (PDT) is a treatment that combines photosensitive drugs with light to induce phototoxic response in target cells, primarily through oxidative damage. Few cases have reported the combination of PDT with antifungal agents to successfully apply to treat Candida infection. We present a case of cutaneous mass caused by Candida albicans (C.albicans) treated solely with 5-aminolevulinic acid (ALA)- PDT. A 21-year-old female presented with a cutaneous lesion on her right elbow,. characterized by erythema, nodules, and cysts that had persisted for 3 months after surgical excision. The diagnosis of infectious granulomas caused by C. albicans was confirmed through tissue histopathological, morphology and molecular sequence of the isolated pathogen. The lesion was completely resolved after two sessions of ALA-PDT adminstered 9 days apart. During the 6-month follow-up, there were no signs of relapse. This case suggested that mono-ALA-PDT can be effective treatment option for single lesion on the body surface caused by C. albicans deep infection.

Invasive fungal infections cause over 3.7 million deaths worldwide annually, underscoring the critical need for new antifungal agents. Developing selective antifungal agents is challenging due to the shared eukaryotic nature of both fungal and mammalian cells.

In this study, a nanocomposite based on copper oxide-zinc oxide nanoparticles and Gum Arabic (GA@CuO-ZnO nanocomposite) was successfully synthesized using green method. Characterization results revealed that the prepared nanocomposite appeared at the nanoscale level, showed excellent dispersion, and formed stable colloidal nano-solutions. The bimetallic GA@CuO-ZnO nanocomposite was evaluated for its anticancer, antibacterial, and antifungal properties.

Purpose: To evaluate the physical and mechanical properties after brushing and microbial adhesion of printed resins (PRs) and heat-polymerized resins (HRs) for occlusal devices (ODs).
Materials And Methods: Knoop microhardness and roughness were evaluated in three measurements before and after brushing with detergent or dentifrice. Flexural strength and modulus of elasticity were assessed by 3-point bending, and the adhesion of Candida albicans and Streptococcus mutans was evaluated by colony-forming units per milliliter (CFU/mL) and metabolic activity using the XTT assay only without brushing.

Based on DMR022 [(AEEA-Gly)-AEEA-amphotericin B methyl ester, AEEA is the abbreviation of 8-amino-3,6-dioxaoctanoic acid] and DMR031 [(AEEA)-amphotericin B methyl ester], DMR040 [(AEEA)-amphotericin B methyl ester] was further designed and synthesised. Firstly, DMR040 was assessed for its antifungal activity and haemolytic toxicity with the broth dilution method and sterile defibrinated sheep blood, respectively. The minimal inhibitory concentration (MIC) of DMR040 (2 μg/mL) against Candida albicans ATCC 10231 and ATCC 90028 was reduced by 2 times compared to that of amphotericin B (1 μg/mL).
