Journal ArticleDOI
Diet-induced changes in AChE activity after long-term exposure.
Rosilene Rodrigues Kaizer,Adriane Cismoski da Silva,Vera Maria Morsch,Maísa Corrêa,Maria Rosa Chitolina Schetinger +4 more
TL;DR: The results indicate that HS and HF diets produced mainly inhibition in acetylcholine degradation, which probably indicates a chronic alteration induced by these diets on the cholinergic system.
Journal ArticleDOI
Piracetam Prevents Scopolamine-Induced Memory Impairment and Decrease of NTPDase, 5′-Nucleotidase and Adenosine Deaminase Activities
Patricia C. Marisco,Fabiano B. Carvalho,Michelle Melgarejo da Rosa,Bruna Amanda Girardi,Jessié Martins Gutierres,Jeandre Augusto dos Santos Jaques,Ana Paula Snovarski Salla,Victor C. Pimentel,Maria Rosa Chitolina Schetinger,Daniela B.R. Leal,Carlos Fernando Mello,Maribel Antonello Rubin +11 more
TL;DR: Piracetam-induced improvement of memory is associated with protection against oxidative stress and maintenance of NTPDase, 5′-nucleotidase and ADA activities, and suggest the purinergic system as a putative target of piracetam.
Journal ArticleDOI
Effects per se of Organic Solvents in the Cerebral Acetylcholinesterase of Rats
Adriana D C Obregon,Maria Rosa Chitolina Schetinger,Maísa M Correa,Vera Maria Morsch,José Edson Paz da Silva,Marcos A. P. Martins,Helio G. Bonacorso,Nilo Zanatta +7 more
TL;DR: Methyl and ethyl alcohol may be the best organic solvent choice for testing new compounds on AChE activity in vitro, according to results studied in different rat brain regions.
Journal ArticleDOI
Effect of Group 13 metals on porphobilinogen synthase in vitro.
TL;DR: Al3+, Ga3+, and In3+ inhibit PBGS by competing with Zn2+, whereas Tl3+ and In 3+ inhibit bovinePBGS by directly oxidizing essential sulfhydryl groups.
Journal ArticleDOI
The activity and expression of NTPDase is altered in lymphocytes of multiple sclerosis patients.
Roselia Maria Spanevello,Cinthia M. Mazzanti,Roberta Schmatz,Gustavo R. Thomé,Margarete Dulce Bagatini,Maísa Corrêa,Cíntia Saydelles da Rosa,Naiara Stefanello,Luziane Potrich Bellé,Maria Beatriz Moretto,Liliane Oliveira,Vera Maria Morsch,Maria Rosa Chitolina Schetinger +12 more
TL;DR: The regulation of ATP and adenosine levels by NTPDase and ADA activities may be important to preserve cellular integrity and to modulate the immune response in MS.
