Microneedling Radiofrequency for Acne Vulgaris in Adolescents as a Promising Device-Based Treatment: A Clinical Case Series.

Acne vulgaris is a persistent inflammatory condition affecting the sebaceous unit, in whose pathophysiology the Propionibacterium acnes (P. acnes) play an important role, and that can have major psychological effects. The current study aims to investigate the safety and efficacy of an innovative fractional microneedle radiofrequency (RFMN) device for acne management in adolescents.

Enhanced Anti-Melanoma Activity of Nutlin-3a Delivered via Ethosomes: Targeting p53-Mediated Apoptosis in HT144 Cells.

This study evaluated ethosomes as a novel nanodelivery system for nutlin-3a, a known MDM2 inhibitor and activator of the p53 pathway, to improve nutlin-3a's poor solubility, limiting its bio-distribution and therapeutic efficacy. The potential of nutlin-3a-loaded ethosomes was investigated on two in vitro models of melanoma: the HT144 cell line p53 and the SK-MEL-28 cell line p53. Nutlin-3a-loaded ethosomes were characterized for their physicochemical properties and used to treat melanoma cells at different concentrations, considering nutlin-3a solution and empty ethosomes as controls.
