Studies have confirmed the effectiveness of comparative models and evidence has contributed to clarifying adult brain plasticity phenomenon when exposed to different stimuli. The expression of c-Fos has been widely used to identify brain areas involved in different behavioral stimuli. The purpose of the present study was to map the expression of c-Fos protein in different telencephalic areas of the lizard Tropidurus hygomi after they were exposed to visual stimuli with another individual of the same species in different social contexts. Lizards were allocated to one of four groups: 1) control group (CTL) – males not exposed to any other animal; 2) exposure to juvenile (EJU) – males exposed to a juvenile; 3) exposure to male (EMA) – males exposed to another adult male; and 4) exposure to females (EFE) –males exposed to female. The EFE group exhibited a greater number of c-Fos + cells in cortical areas (medial cortex – MC and dorsomedial cortex – DMC) and in amygdala (AMY), showing a possible relationship between these structures and beh...

Family dinner frequency, family relationship, life satisfaction (LS), self-perceived health and anxiety were assessed by validated questionnaires. Of 14,274 participants, 50.6% were boys and 71.4% were urban residents, with a mean (SD) age of 12.28 (3.16) years. Family dinner frequency was significantly correlated with LS (boys: β = 0.27, p
In this study we explored the use of a natural compound rubusoside (RUB) as a solubilizer to enhance the solubility of a fluorescence-labeled C6-Ceramide (NBD C6-Ceramide) and to characterize its pharmacokinetics and tissue distribution in an animal model. RUB significantly enhanced the solubility of NBD C6-Ceramide by forming nanomicelles, and efficiently delivered NBD C6-Ceramide in rats by oral and intravenous administration. RUB loaded 1.96% of NBD C6-Ceramide in the nanomicelles and solubilized it to a concentration of 3.6 mg/mL in water. NBD C6-Ceramide in nanomicelles remained stable in aqueous solutions, all...

ConteAbstractInflammation ensuing from vascular injury promotes intimal hyperplasia (IH) and restenosis. Resolvin D1 (RvD1) is a lipid mediator that attenuates IH in vivo when delivered locally to the vessel wall in animal models. We tested the hypothesis that peri-procedural oral administration of RvD1 could blunt the local inflammatory response to angioplasty, and attenuate downstream IH. Carotid angioplasty was per...
