    Abstract : The aim with this thesis was to assess the impact of prenatal ultrasound exposure on psychotic illness, childhood brain tumors (CBT) and school achievement, and to evaluate prenatal X-ray exposure and the risk of CBT.In a cohort study, children born in Malmö 1973-1978, where prenatal ultrasound was used routinely, were considered exposed (n=13, 212) and children born at hospitals with no use of ultrasound, were considered unexposed (n=357,733).

  4. 2. Mental retardation in children : an epidemiological and etiological study of mentally retarded children born 1959-1970 in a northern Swedish county

    Author : Hans K:son Blomquist; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mental retardation; Incidence; Prevalence; Etiology; CNS handicap; Fragile site X chromosome; Maternal phenylketonuria; Late introduced dietary treatment; Intrauterine irradiation;

    Abstract : In an unselected series of mentally retarded children in the county of Västerbotten, Sweden, the annual incidence of children with severe mental retardation (SMR) (IQ < 50) and alive at the age of one year decreased from 5.3 per 1,000 in 1959 - 1963 to 3.1 per 1,000 in 1967 -1970.

  5. 3. Nuclear hormone receptor signaling in the developing CNS : studies on the retinoid receptors RAR and RXR, and the orphan receptors NURR1, NOR1 and NGFI-B

    Author : Ludmila Solomin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The nuclear hormone receptor superfamily comprises more than sixty members, including receptors for steroids, thyroid hormone, vitamin D and retinoids. Many nuclear receptors function as ligand-induced transcription factors that upregulate expression of specific target genes. READ MORE

  6. 4. A study of the generation of diversity in the central nervous system

    Author : Joanna Applequist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Developmental biology is concerned with understanding the mechanisms that govern the generation of a whole organism starting from one single cell. In the central nervous system (CNS) the development of different classes of neurons and glial cells involves both extrinsic signals and intrinsic cues that together govern the specification of different cell fates dependent on position within the CNS and the time of generation.

  7. 5. Megalin, an Endocytotic Receptor with Signalling Potential

    Author : Mårten Larsson; Lars Rask; Bo Åkerström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Megalin; LRP-2; Postsynaptic density-95; Retinol-binding protein; Oligodendrocytes; Central nervous system; Biokemi; Biochemistry; Biokemi;

    Abstract : Megalin is an endocytotic receptor belonging to the low-density lipoprotein family. It has often been viewed only as merely a scavenger receptor of absorptive and secretory epithelia. Recent work has revealed that the megalin intracellular domain contains several motifs potentially binding proteins involved in signal transduction. READ MORE
