Plastic intake does not depend on fish eating habits: Identification of micropl...
Dantas, Natália Carla Fernandes de Medeiros; Duarte, Oscar S.; Ferreira, Wellington C.; Ayala, Alejandro P.; Rezende, Carla F.; Feitosa, Caroline V.This study aims to identify, classify, quantify the ingested microplastic by marine teleost fish, in order to analyze the relationship between microplastic and trophic guilds. Food items of 214 individuals of Opisthonema oglinum, Bagre marinus, Cathorops spixii, Sciades herzbergii, Chloroscombrus chrysurus, Conodon nobilis, Haemulopsis corvinaeformis were analyzed. The species were classified according to their...
Supramolecular interactions between β‐lapachone with cyclodextrins studied usin...
Xavier‐Junior, Francisco H.; Rabello, Marcelo M.; Hernandes, Marcelo Z.; Dias, Marília E.S.; Andrada, Otoni H.M.S.; Bezerra, Beatriz P.Supramolecular interactions between β-lapachone (β-lap) and cyclodextrins (CDs) were investigated by isothermal titration calorimetry. The most favorable host: guest interaction was characterized using X-ray powder diffraction (XRD), differential scanning calorimetry and thermogravimetry (DSC/TG), spectroscopy (FT-IR), spectroscopy (2D ROESY) nuclear magnetic resonance (NMR), and molecular modeling. Phase solub...
