Cortical Serotonin Type-2 Receptor Density in Parents of Children with Autism Spectrum Disorders / Jeremy GOLDBERG in Journal of Autism and Developmental Disorders, 39-1 (January 2009)

ANDERSON, Auteur ; Claude NAHMIAS, Auteur ; Geoffrey B. C. HALL, Auteur ; Ann THOMPSON, Auteur Année de publication : 2009 Article en page(s) : p.97-104 Langues : Anglais (eng) Mots-clés : Autism Positron-emission-tomography Setoperone [18Fluoro]setoperone Serotonin Endophenotype Index. décimale : PER Périodiques Résumé : Parents (N = 19) of children with autism spectrum disorders (ASD) and adult controls (N = 17) underwent positron emission tomography (PET) using [18F]setoperone to image cortical serotonin type-2 (5-HT2) receptors. The 5-HT2 binding potentials (BPs) were calculated by ratioing [18F]setoperone intensity in regions of interest (ROI) to cerebellar intensity. Cortical 5-HT2 BPs were significantly lower in parents compared to controls and platelet 5-HT levels were significantly negatively correlated with cortical 5-HT2 BP in parents. Lower cortical 5-HT2 receptor density in parents of children with ASD is consistent with reports of diminished 5-HT2 expression and functioning in individuals with ASD. Further research should examine the relationship of reduced 5-HT2 receptor expression to underlying causation and to clinical and neurochemical correlates of autistic behavior.

Regional cerebral glucose metabolism of newborn infants measured by positron emission tomography / Lex W. DOYLE in Developmental Medicine & Child Neurology, 25-2 (April 1983)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 25-2 (April 1983) . - p.143-151 Titre : Regional cerebral glucose metabolism of newborn infants measured by positron emission tomography Type de document : Texte imprimé et/ou numérique Auteurs : Lex W. DOYLE, Auteur ; Claude NAHMIAS, Auteur ; Gunter FIRNAU, Auteur ; David B. KENYON, Auteur ; E. Stephen GARNETT, Auteur ; John C. SINCLAIR, Auteur Année de publication : 1983 Article en page(s) : p.143-151 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The new diagnostic technique, positron emission tomography with 18F-2-fluoro-2-deoxy-D-glucose (18FDG), was used to measure regional cerebral glucose metabolism in five newborn infants with demonstrated structural abnormalities of the brain. 18FDG was synthesized, diluted in normal saline and injected intravenously. After one hour, tomographic slices of the brain were obtained, the level of the slices being defined relative to the cerebral ventricles. Glucose metabolism of grey- and white-matter structures in the brain could be differentiated clearly. Decreased glucose metabolism was identified in regions of the brain shown by computerized axial tomography to be structurally abnormal. Positron emission tomography is a promising new diagnostic tool for the study of newborn infants with suspected abnormalities of brain function.
