As queimaduras são as causas mais comuns de lesões cutâneas. Para dinamizar o processo de cicatrização são utilizados polímeros naturais em substituição aos polímeros sintéticos. A pectina e a galactomanana de jucá (Caesalpinia ferrea) e o alginato reticulado com cálcio são atóxicos e biodegradáveis. E juntamente com os extratos dos frutos do jucá apresentaram propriedades bactericidas e toxicidade baixa, agem ...
This work describes the development and characterization of Magnetic Solid Lipid Nanoparticles (MSLN) for application in magnetic hyperthermia and controlled release of oncocalyxone A. Ferrofluid was obtained by coprecipitation method of the salts Fe (II) and Fe (III) in alkaline medium, whose nature (magnetite-Fe3O4) was confirmed by X-ray Diffraction (XRD). For the optimization of systems, was necessary the d...
This study assessed the antioxidant, antimicrobial, anticancer and neuroprotective activities of the kappa(k)-carrageenan isolated from the red alga Hypnea musciformis (Hm-SP). The chemical spectrum of the k-carrageenan fromHm-SPwas confirmed by Fourier transform infrared (FT-IR) spectroscopy.Hm-SP revealed an antibacterial and antifungal action against Staphylococcus aureus and Candida albicans, respectively. ...
