METHODS High-resolution MR scans with a surface coil placed over the nasion were performed in two patients with Kallmann syndrome. Coronal 3-mm thick(More)
We have examined two features of neuroblastoma cells that had not been well-characterized in a xenogeneic model: The cells display unusual immunologic properties in other experimental systems, and the original tumors display widespread and characteristic patterns of metastasis. To determine the most appropriate immunodeficient host for primary tumor growth,(More)
Evidence is presented for the occurrence of a locus for schizotaxia on the short arm of chromosome 6. This derives from study of 63 informative members of seven pedigrees in which the proband and a parent (or a sib of parent) suffered with schizophrenia and other kin were either normal or fell within a spectrum of conditions related to schizophrenia.

The identification of nicotinamide-N1-oxide as a metabolite in the urine of a schizophrenic patient prompted a study of the relative metabolism of nicotinic acid and nicotinamide in mental patients and healthy volunteers. Metabolites quantified included N1-methyl-2-pyridone-5-carboxamide, N1-methyl-4-pyridone-3-carboxamide, N1-methylnicotinamide,(More)
