In this study, we assessed the oxidative stress parameters in rats submitted to an animal model of mania induced by ouabain (OUA), which included the use of lithium (Li) and valproate (VPA). Li and VPA treatment reversed and prevented the OUA-induced damage in these structures, however, this effect varies depending on the brain region and treatment regimen.(More)
There is a body of evidence suggesting that BDNF is involved in bipolar disorder (BD) pathogenesis. Intracerebroventricular (ICV) injection of ouabain (OUA), a specific Na(+)/K(+) ATPase inhibitor, induces hyperlocomotion in rats, and has been used as an animal model of mania. The present study aims to investigate the effects of the lithium (Li) and(More)
OBJECTIVE To assess the presence of anxiety disorders and quality of life in patients with insulin-dependent type 2 diabetes. METHODS Case-control study of 996 patients with type 2 diabetes and 2,145 individuals without diabetes. The sole inclusion criterion for the case group was insulin-dependent type 2 diabetes. We compared the case and control groups(More)
Several studies have suggested that alterations in brain-derived neurotrophic factor (BDNF) and increased oxidative stress have a central role in bipolar disorder (BD). Intracerebroventricular (ICV) injection of ouabain (OUA) in rats alters oxidative stress parameters and decreases BDNF levels in the brain. In this context, the present study aims to(More)
This study evaluated the association of mood disorders, suicidal ideation and the quality of life in patients with type 2 diabetes. We used a case-control study employing 996 patients suffering with type 2 diabetes (using insulin for over 1 year), and 2.145 individuals without diabetes. The groups were then used to evaluate the presence of different mood(More)
Although electroconvulsive therapy (ECT) has been used as a treatment for mental disorder since 1930s, little progress has been made in the mechanisms underlying its therapeutic or adverse effects. The aim of this work was to analyze the expression of DARPP-32 (a protein with a central role in dopaminergic signaling) in striatum, cortex, hippocampus and(More)
This work was performed in order to determine the level of oxidative damage and antioxidant enzymes activities late after acute and chronic electroconvulsive shock (ECS) in rats. We measured oxidative parameters in hippocampus, cortex, and striatum, at 45, 60, 90 and 120 days after a single or multiple ECS. We demonstrated an increase in lipid peroxidation(More)
Although several advances have occurred over the past 20 years concerning refining the use and administration of electroconvulsive therapy to minimize side effects of this treatment, little progress has been made in understanding the mechanisms underlying its therapeutic or adverse effects. This work was performed in order to determine the level of(More)
Neonatal Escherichia coli meningitis continues to be an important cause of mortality and morbidity in newborns worldwide. The aim of this study was to investigate the cytokines/chemokines, brain-derived neurotrophic factor (BDNF) levels, blood-brain barrier integrity in neonatal rats following E. coli K1 experimental meningitis infection and subsequent(More)
The present study aimed to investigate the effects of mood stabilizers, specifically lithium (Li) and valproate (VPA), on the PI3K/Akt signaling pathway in the brains of rats subjected to the ouabain (OUA)-induced animal model of mania. In addition, the effects of AR-A014418, a GSK-3β inhibitor, on manic-like behavior induced by OUA were evaluated. In the(More)
