Three magnetic fluid (MF) samples containing gamma-Fe2O3 (maghemite) nanoparticles surface-coated with either meso-2,3-dimercaptosuccinic acid (DMSA), citric acid or lauric acid were prepared, characterized, and assessed for their cytotoxic potential on the human SK-MEL-37 melanoma cell line. Ultra-structural analysis was also performed using transmission(More)
Small animal models are particularly suitable for lung preservation studies, because they are simple and costeffective. This brief communication focuses on the technical description of an ex vivo lung perfusion model in rats by means of a commercially available apparatus, which was the first to be installed in a thoracic surgery research laboratory in(More)

In course of a screening for small molecules presenting potential anticancer properties, a known monoterpene indole alkaloid named vallesiachotamine was isolated from the leaves of Palicourea rigida (Rubiaceae) collected in the Brazilian Cerrado. The structure was determined by spectroscopic methods, mainly 1D- and 2D-NMR and its biological activities were(More)
The in vitro growth of embryonic stem cells (ESCs) is usually obtained in the presence of murine embryonic fibroblasts (MEF), but new methods for in vitro expansion of ESCs should be developed due to their potential clinical use. This study aims to establish a culture system to expand and maintain ESCs in the absence of MEF by using murine embryonic stem(More)
