Evaluación de la citotoxicidad, genotoxicidad y toxicidad subcrónica de diéster...
Canabrava, Natália do Vale; Silva, Jose Ytalo Gomes da; Silva, Bruno Bezerra da; Holanda, Marcelo Oliveira; Lima, Carla Laine SilvaP-methoxycinnamic diesters from carnauba wax powder (PCO - C) – cinnamic acid derivate – have been associated with new properties such as hypolipidemic, hypocholesterolemic and hypoglycaemic effects in mice. The present study aimed to investigate the safety profile of PCO - C by evaluating the subchronic oral toxicity, genotoxicity and mutagenicity using in vivo experimental models. Therefore, for the present r...

Silva, Geysa Janne Sousa; Santos, Fabelina Karollyne Silva dos; Marques, Márcia Maria Mendes; Peron, Ana PaulaThis study aimed to evaluate the cytotoxicity and genotoxicity and determine the LC50 concentration of powdered infant formulas widely marketed in South American countries. To this, milk samples, called as A, B, C and D, were analyzed in root meristem cells of Allium cepa, at concentrations of 0.075; 0.15 and 0.30 g mL-1, for 24 and 48 hours; and through cell viability in culture of normal line cells, via MTT t...
Toxicity of food flavorings to ex-vivo, in vitro and in vivo bioassays
Santos, Fabelina Karollyne da Silva dos; Marques, Márcia Maria Mendes; Van Tilbulrg, Maurício Fraga; Guedes, Maria Izabel FlorindoThis study evaluated the toxicity of food flavorings of mint, cinnamon and lemon in meristem root cells of Allium cepa, in pure form (as marketed) and in the concentrations of 12.5, 25, and 50%, after 24 and 48 hours of exposure; in Vero cell culture evaluated by MTT test and in nauplii of Artemia salina, both tests used flavorings in pure form and in the concentrations of 0.78, 1.56, 3.12, 6.25, 12.5, 25, and ...
Antioxidant activity and physicochemical analysis of passion fruit (Passiflora ...
Lima-Neto, Abelardo Barbosa Moreira; Marques, Márcia Maria Mendes; Mendes, Francisca Noélia Pereira; Vieira, Ícaro Gusmão PintoThe objective of this study was to determine the proximal composition, the physical and chemical characteristics and the in vitro antioxidant capacity (DPPH, ABTS and FRAP) of the pulp of the wild passion fruit (Passiflora glandulosa Cav.) from Cariri region, Ceara, Brazil. The results showed that the proximal composition and the caloric value of this passion fruit are similar to other species, but with a high ...
