15. [Extrato das folhas de Arrabidaea chica (Fridericia chica) mostrou potencial ação no combate à cardiotoxicidade induzida pela doxorrubicina]
RESUMO A doxorrubicina (dox) é um medicamento antineoplásico que induz cardiotoxicidade por estresse oxidativo. Os flavonoides são antioxidantes extraídos de plantas como Camellia sinensis e Arrabidaea chica (Fridericia chica). Esta pesquisa objetivou avaliar efeitos protetores do extrato de A. chica (AC), comparado ao de C. sinensis (CS), frente ao estr

18. Effect of erythrosine and phloxine from xanthene food dyes on oxidative stress in Chinese hamster ovary cells
Abstract Objective of this study was to investigate the changes of oxidative stress parameters in Chinese hamster ovary (CHO) cells exposed to xanthene food dyes (erythrosine and phloxine), commonly-used azo dyes in the food industry. For this purpose, glutathione (GSH) and malondialdehyde (MDA) levels, glutathione peroxidase (GPx) and catalase (CAT) activit

19. Effects of pectin and tomato paste as a natural antioxidant on inhibition of lipid oxidation and production of functional chicken breast sausage
Abstract In this study antioxidant effects of pectin and tomato paste (TP) on lipid oxidation and production of functional chicken breast sausage during refrigerated storage for 14 days were evaluated. Raw chicken sausage samples were enriched with different levels of TP containing 0, 1, 2 and 10% and 1% pectin, and peroxide value (PV), thiobarbituric acid r

20. Seed priming with seaweed extract mitigate heat stress in spinach: effect on germination, seedling growth and antioxidant capacity
ABSTRACT Spinach seeds are sensitive to high temperatures during germination and plant growth. It is known that seed priming with water or with seaweed extract (SWE) may enhance germination and seedling growth. The objective of this study was to evaluate the effects of seed priming with SWE (Ascophyllum nodosum) on the germination, seedling growth and antiox

21. “Half-Sandwich”/RuII Anticancer Complexes Containing Triphenylphosphine and p-Substituted Benzoic Acids
Mononuclear and binuclear RuII/arene/triphenylphosphine complexes with p-substituted benzoic acid derivatives were prepared and characterized. These monocationic complexes of type [Ru(η6-p-cymene)(PPh3)L] (L = benzoic acid (1), p-hydroxybenzoic acid (2), p-nitrobenzoic acid (3) and terephthalic acid (4)) were characterized using various techniques, such as
