Spatial memory impairments in a prediabetic rat model
Soares, E.; Prediger, R. D.; Nunes, S.; Castro, A. A.; Viana, S .D.; Lemos, C.; Souza, C. M. De; Agostinho, P.; Cunha, R. A.; Carvalho, E.Diabetes is associated with an increased risk for brain disorders, namely cognitive impairments associated with hippocampal dysfunction underlying diabetic encephalopathy. However, the impact of a prediabetic state on cognitive function is unknown. Therefore, we now investigated whether spatial learning and memory deficits and the underlying hippocampal dysfunction were already present in a prediabetic animal m...
Electrochemical evaluation of lipophilic antioxidants from Iryanthera juruensis...
Silva,D. H. S.; Pereira,F. C.; Yoshida,M.; Zanoni,M. V. B.TLC autographic assays revealed in the hexane extract of Iryanthera juruensis (Myristicaceae) the presence of two compounds, with antioxidant properties towards beta-carotene. They were isolated and identified as 3-methyl-sargachromenol (1) and sargachromenol (2). Further investigation of the hexane extract led to isolations of 3-methyl-sargaquinoic acid (3) and sargaquinoic acid (4). The electrochemical behavi...
