SUMMARY: Human skin melanin was stained using the Fontana's silver nitrate method and Schmorl method. The results showed that, in the Fontana's silver nitrate method, melanin and silver-bound cells were black and other tissues were red. When stained using the Schmorl method, effects on melanin differed b...

Abstract With the development of new cancer therapies, systemic toxicity profile and effects on survival achieved an important improvement. However, a constellation of toxicities has emerged, even more remarkably, cutaneous adverse events. This report, developed by a board of Brazilian experts in oncoder...
Urea's thermal instability and burning on sensitive skin can cause problems for cosmetic formulations. To overcome these drawbacks, urea was incorporated into ordered mesoporous silica (SBA-15). SBA-15 was synthesized using tetraethyl orthosilicate and Pluronic® P123 in an acid medium. Urea (20 wt.%) wa...

Abstract Purpose: To compare the use of new cyanoacrylate surgical adhesive associated with macroporous tapes in cutaneous synthesis. Methods: Male Wistar rats with a longitudinal incision of 4cm were used on the back, divided into four groups: GI used octyl-cyanoacrylate (Dermabond®), GII used N-2-bu...
Abstract Purpose: To evaluate the effects and mechanisms of andiroba-based emulsion (ABE) topical treatment on full-thickness cutaneous wounds in rats. Methods: The wounds were harvested on days 3, 7, 15, and 20 post-surgery. Wound contraction rate, quantitative immunohistochemistry [macrophages, myofi...
