Background: Dermoscopy is a non-invasive, cost-effective tool useful in the assessment of pigmented lesions. The aim of this study was to analyze the dermoscopic features in excised melanomas in a tertiary hospital in Brazil and the influence of Breslow thickness on the dermoscopic features observed.
Methods: An observational, cross-sectional study in which dermoscopic images of 43 melanomas were evaluated.
Owing to the growing need for natural materials in different fields, studying melanin production from biological sources is imperative. In the current study, the extracellular melanin pigment was produced by the fungus Curvularia soli AS21 ON076460. The factors that affect the production of melanin were optimized by the Plackett-Burman design (P-BD).

The structural analysis confirmed the formation of crystalline nanostructured BaTiO with mixed tetragonal and hexagonal phases, and the film deposited at 150 °C has the best crystallinity and largest particle size. The optical energy gap of the BaTiO nanostructure decreases from 3.
