Journal ArticleDOI
Effects of a static magnetic field on cell growth and gene expression in Escherichia coli.
Lucia Potenza,Luca Ubaldi,Roberta De Sanctis,Roberta De Bellis,Luigi Cucchiarini,Marina Dachà +5 more
TL;DR: The results show alterations induced by SMF in terms of increased cell proliferation and changes in gene expression compared with control groups, which suggests that exposure to a magnetic field may stimulate transposition activity.
Journal ArticleDOI
In vitro protective effect of Rhodiola rosea extract against hypochlorous acid-induced oxidative damage in human erythrocytes.
Roberta De Sanctis,Roberta De Bellis,Carla Scesa,Umberto Mancini,Luigi Cucchiarini,Marina Dachà +5 more
TL;DR: This study demonstrates that R. rosea is able to significantly protect, in a dose‐dependent manner, human RBC from glutathione (GSH) depletion, glyceraldehyde‐3‐phosphate dehydrogenase (GAPDH) inactivation and hemolysis induced by the oxidant.
Journal ArticleDOI
Intracellular flavonoids as electron donors for extracellular ferricyanide reduction in human erythrocytes.
TL;DR: Myricetin and quercetin, which accumulate in large amounts in red blood cells, act as intracellular substrates of a pCMBS-sensitive trans-plasma membrane oxidoreductase, which may represent a novel mechanism whereby these flavonoids exert beneficial effects under oxidative stress conditions.
Journal ArticleDOI
Dehydroascorbic acid irreversibly inhibits hexokinase activity.
Mara Fiorani,Roberta De Sanctis,Francesca Scarlatti,Luciana Vallorani,Roberta De Bellis,Giordano Serafini,Marzia Bianchi,Vilberto Stocchi +7 more
TL;DR: Results are consistent with the possibility that covalent binding of the reagent with a thiol group of cysteine is a critical event for the DHA-mediated loss of hexokinase activity.
Journal ArticleDOI
Nutritional, antioxidant and sensory properties of functional beef burgers formulated with chia seeds and goji puree, before and after in vitro digestion
Elena Antonini,Luisa Torri,Maria Piochi,Giorgia Cabrino,Maria Assunta Meli,Roberta De Bellis +5 more
TL;DR: In comparison to control burgers, polyunsaturated fatty acids doubled or tripled in samples containing chia seeds; polyphenols and antioxidant capacities increased up to 70% and malondialdehyde values were reduced up to 50% in burgers formulated with both ingredients.
