The molecular basis of complex neuropsychiatric disorders most likely involves many genes. In recent years, specific genetic variations influencing risk for schizophrenia and other neuropsychiatric disorders have been reported. We have used custom DNA microarrays and qPCR to investigate the expression of putative schizophrenia susceptibility genes and(More)
Five infants, three dying neonatally and two later in the first year of life, had renal, hepatic, and pancreatic dysplasia, a combination of abnormalities first described by Ivemark et al [1959]. The renal malformation consisted of cystic dysplasia, with abnormally differentiated ducts, deficient nephron differentiation, and glomerular cysts. The hepatic(More)
This study quantitatively explored the dendritic/spine extent of supragranular pyramidal neurons across several cortical areas in two adult male subjects who had undergone a callosotomy several decades before death. In all cortical areas, there were numerous atypical, supragranular pyramidal neurons with elongated "tap root" basilar dendrites. These(More)
We studied the effect of hyperviscosity on plasma glucose concentration, endogenous glucose production, and plasma insulin concentration in 12 term mixed breed newborn lambs. After a 7-hr fast, 0.45% saline was infused at a constant rate for 6 hr during which time hourly plasma glucose and 3-hourly plasma insulin concentrations were determined. A glucose(More)
Post-hepatic insulin secretion was measured in six chronically catheterized fetal lambs (fetal weight 2.8 +/- 0.3 kg, mean +/- S.E.M.) and the results were compared with those obtained in nine prematurely delivered newborn lambs (birth weight 3.1 +/- 0.3 kg and postnatal age 1.3 +/- 0.2 days). The fetal and neonatal lambs received either a 0.45% saline or a(More)
