Is basal cerebral blood flow dependent on the nitric oxide pathway in elderly but not in young healthy men?
We conclude that compared to young subjects, in old people CBF is impaired, and dependent on the intactness of the nitric oxide pathway.
In this hypothesis-generating outcome study, premature boys, but not girls, benefited from amino acid administration directly following birth. The observed lower mental developmental index in a subgroup of girls, however, warrants further studies.
