Neonatal hypoxia-ischemia (HI) has been extensively studied in a rat model characterized by unilateral brain damage (Rice-Vannucci Model). However, as well as in humans, each rat brain hemisphere is distinctly involved in cognitive functions, as for example retrieval of emotionally based memory, and neurochemical asymmetries have been described. In this(More)
Several species of the genus Passiflora, known in Brazil as "maracujá", have widespread use in folk medicine as sedatives and tranquillizers. The anxiolytic activity of hydroethanol extracts of P. alata and P. edulis leaves was evaluated using the elevated plus-maze test. The extracts presented anxiolytic activity in dosages around 50, 100 and 150 mg/kg.

The naturally occurring flavonoids, chrysin (5,7-dihydroxyflavone) and apigenin (5,7,4'-trihydroxyflavone), and the synthetic compound, 6,3'-dinitroflavone have been recently reported to selectively bind with high affinity to the central benzodiazepine receptor, and to exert powerful anxiolytic and other benzodiazepine-like effects in rats. Their chemical(More)
This report describes the effects of the antiepileptic agent gabapentin on anxiety and memory. Male Wistar rats received intraperitoneal administrations of gabapentin (10, 30 and 100mg/kg), diazepam (1 mg/kg), saline or diazepam vehicle 30 minutes prior to experimental procedures. Animals were: (1) tested on step-down inhibitory avoidance (footshock 0.3 mA)(More)
OBJECTIVE To characterize the participatory and democratic creation of the Brazilian guidelines for biorepositories and biobanks of human biological material with the purpose of research based on the ethical principles of human dignity, autonomy, beneficence, justice, and precaution. METHODS An interdisciplinary work group was constituted to prepare the(More)
The alcoholic extract of Pfaffia glomerata roots (100, 500, 1000 mg/kg, intraperitoneally (i.p.), and 500, 1000, 1500 mg/kg, per os) was studied in several behavioral animal models for the evaluation of central activity: open field, barbiturate sleeping time, pentilenotetrazole (PTZ)-induced convulsions, elevated plus-maze, step-down inhibitory avoidance(More)
Informed consent is recognized as a primary ethical requirement to conduct research involving humans. In the investigations with the use of human biological material, informed consent (IC) assumes a differentiated condition on account of the many future possibilities. This work presents suitable alternatives for IC regarding the storage and use of human(More)
