Expression and secretion of neurotrophins, including brain-derived neurotrophic factor (BDNF), are regulated also by neuronal activity. Data available in the literature suggest that BDNF central levels are influenced by light and dark. Diurnal changes of BDNF mRNA and protein contents have been demonstrated in the rat central nervous system. Based on these(More)
The increased use of hormonal therapies over the last years has led to improve the knowledge of pharmacological, biochemical and metabolic properties of several progestins and their effects in target tissues, such as the central nervous system. Progesterone and synthetic progestational agents are able to modulate the synthesis and release of several(More)
Steroids arriving from the gonads via the circulation modulate brain function, affecting gender differentiation and sexually differentiated behavioral responses, but also the ability of the brain to process, store and retrieve sensory information. Androgens play a pivotal neuroactive role during the "organizational/developmental" phase, mainly in the(More)
The aim of this study was to investigate the effects of nomegestrol acetate (NOMAc) on the central nervous system by analyzing the neurosteroid allopregnanolone and the opioid beta-endorphin (beta-endorphin). 104 Wistar female rats were used in this study; one group of fertile and one group of ovariectomized rats were used as control. The others were(More)
AIMS The present study aims at evaluating the effect of a 2-week treatment with testosterone (T), dihydrotestosterone (DHT) and estradiol valerate (E(2)V) on brain and plasma beta-endorphin (beta-END) concentrations in gonadectomized rats of both sexes. METHODS Eight groups of female and 8 groups of male Wistar rats were included. For each sex, 1 group of(More)
