Consumption of caffeine, an adenosine receptor antagonist, was found to be inversely associated with the incidence of Alzheimer's disease. Moreover, caffeine protects cultured neurons against… Expand
Proposal of a guanine-based purinergic system in the mammalian central nervous system.
- A. Schmidt, D. Lara, D. Souza
- Biology, Medicine

- 1 December 2007
Guanine-based purines have been traditionally studied as modulators of intracellular processes, mainly G-protein activity. However, they also exert several extracellular effects not related to G… Expand
Chronically administered guanosine is anticonvulsant, amnesic and anxiolytic in mice
- E. Vinadé, A. Schmidt, M. E. S. Frizzo, I. Izquierdo, D. Souza

Acute administration of intraperitoneal and oral guanosine has been shown to prevent quinolinic acid and alpha-dendrotoxin-induced seizures in rats and mice. In this study, we investigated the… Expand
Increased serum S100B protein in schizophrenia: a study in medication-free patients.
S100B protein, a calcium binding protein produced and released by glial cells, has been used as a sensitive marker of brain damage. Previous studies have found alterations in peripheral S100B levels… Expand
Behavioral effects of taurine pretreatment in zebrafish acutely exposed to ethanol
