Journal ArticleDOI
Resveratrol prevents memory deficits and the increase in acetylcholinesterase activity in streptozotocin-induced diabetic rats.
Roberta Schmatz,Cinthia M. Mazzanti,Roselia Maria Spanevello,Naiara Stefanello,Jessié Martins Gutierres,Maísa Corrêa,Michelle Melgarejo da Rosa,Maribel Antonello Rubin,Maria Rosa Chitolina Schetinger,Vera Maria Morsch +9 more
TL;DR: It is shown that treatment with resveratrol prevents the increase in AChE activity and consequently memory impairment in diabetic rats, demonstrating that this compound can modulate cholinergic neurotransmission and consequently improve cognition.
Journal ArticleDOI
Effects of resveratrol on biomarkers of oxidative stress and on the activity of delta aminolevulinic acid dehydratase in liver and kidney of streptozotocin-induced diabetic rats
Roberta Schmatz,Luciane Belmonte Perreira,Naiara Stefanello,Cinthia M. Mazzanti,Roselia Maria Spanevello,Roselia Maria Spanevello,Jessié Martins Gutierres,Margarete Dulce Bagatini,Caroline Curry Martins,Fátima Husein Abdalla,Jonas Daci da Silva Serres,Daniela Zanini,Juliano Marchi Vieira,Andréia Machado Cardoso,Maria Rosa Chitolina Schetinger,Vera Maria Morsch +15 more
TL;DR: It is suggested that resveratrol could have a protector effect against hepatic and renal damage induced by oxidative stress in the diabetic state, which was evidenced by the capacity of this polyphenol to modulate the antioxidant defense and to decrease the lipid peroxidation in these tissues.
Journal ArticleDOI
Anthocyanins restore behavioral and biochemical changes caused by streptozotocin-induced sporadic dementia of Alzheimer's type
Jessié Martins Gutierres,Fabiano B. Carvalho,Maria Rosa Chitolina Schetinger,Patricia C. Marisco,Paula Agostinho,Marilia Valvassori Rodrigues,Maribel Antonello Rubin,Roberta Schmatz,Cássia Regina Silva,Giana de Paula Cognato,Júlia Gomes Farias,Cristiane Signor,Vera Maria Morsch,Cinthia M. Mazzanti,Maurício Reis Bogo,Carla Denise Bonan,Roselia Maria Spanevello +16 more
TL;DR: It is demonstrated that ANT is able to regulate ion pump activity and cholinergic neurotransmission, as well as being able to enhance memory and act as an anxiolytic compound in animals with SDAT.
Journal ArticleDOI
Oxidative stress versus antioxidant defenses in patients with acute myocardial infarction.
Margarete Dulce Bagatini,Caroline Curry Martins,Vanessa Battisti,Diogo Gasparetto,Cíntia Saydelles da Rosa,Roselia Maria Spanevello,Mushtaq Ahmed,Roberta Schmatz,Maria Rosa Chitolina Schetinger,Vera Maria Morsch +9 more
TL;DR: The results demonstrated an increase in substances reactive to thiobarbituric acid (TBARS) and carbonyl protein levels in the AMI and risk groups and a decrease in nonenzymatic antioxidants such as vitamin C and vitamin E was observed in AMI patients when compared with the healthy group and the risk group.
Journal ArticleDOI
Quercetin protects the impairment of memory and anxiogenic-like behavior in rats exposed to cadmium: Possible involvement of the acetylcholinesterase and Na+,K+-ATPase activities
Fátima Husein Abdalla,Roberta Schmatz,Andréia Machado Cardoso,Fabiano B. Carvalho,Jucimara Baldissarelli,Juliane Sorraila de Oliveira,Michelle Melgarejo da Rosa,Matheus A.G. Nunes,Maribel Antonello Rubin,Ivana Beatrice Mânica da Cruz,Fernanda Barbisan,Valderi L. Dressler,Luciane Belmonte Pereira,Maria Rosa Chitolina Schetinger,Vera Maria Morsch,Jamile F. Gonçalves,Cinthia M. Mazzanti +16 more
TL;DR: It is shown that quercetin prevents alterations in oxidative stress parameters as well as AChE and Na(+),K(+)-ATPase activities, consequently preventing memory impairment and anxiogenic-like behavior displayed by Cd exposure.
