The Golgi-Cox method was used to study the maturation of the large pyramidal cells of the Vth cortical layer in three groups of adult rats: one subjected to undernutrition during the first month of life, another throughout the first 2 mth of life, and the last one during gestation and the suckling period. The main alterations consist of a decrease in the(More)
Oral high-dose glycine administration has been used as an adjuvant treatment for schizophrenia to enhance glutamate neurotransmission and mitigate glutamate system hypofunction thought to contribute to the disorder. Prior studies in schizophrenia subjects documented clinical improvements after 2 weeks of oral glycine administration, suggesting that brain(More)

Chronic cocaine abusers experience brain and peripheral vascular dysfunction, the severity of which tends to be greater in men than women. The mechanisms underlying these effects of cocaine are unknown. Because nitric oxide (NO) abnormalities play key roles in development of vascular dysfunction in several disorders, we determined whether vascular nitric(More)
