  1. 36. Neurotrophic factors and their receptors in the developing avian retina and its tectal target

    Författare :Miriam Karlsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neurovetenskap; Neurology; Neurologi; Developmental Neurosciences; medicinsk utvecklings- och neurobiologi;

    Sammanfattning : Neurotrophic factors and their receptors are crucial for the formation of neuronal connections and for the neuronal survival during embryonic development of the nervous system. This has particularly been shown by studies of the PNS. LÄS MER

  3. 37. Short-chain retinol dehydrogenases/reductases : Involvement in retinoid metabolism and expression in embryonic and adult mouse

    Författare :Paulina Tuvendal; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; -; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

    Sammanfattning : Retinoids are needed in the embryo to ensure proper development and in the adult forvision, maintenance of epithelia and sperm production. Retinol is oxidised within the cell generating retinal and, irreversibly, retinoic acid. LÄS MER

  4. 38. Teleost retina : a model for study neurogenesis and angiogenesis

    Författare :Satish Srinivas Kitambi; Agneta Mode; Jarema Malicki; Per Kylster; Thomas Burglin; Finn Hallböök; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Teleost models, zebrafish and medaka have become popular models to study various aspects of developmental biology and genetics. The rapid embryonic development, transparent embryos and the availability of many mutants for various developmental and molecular pathways contribute to the usefulness of these models. LÄS MER

  5. 39. BMP - a key signaling molecule in specification and morphogenesis of sensory structures

    Författare :Vijay Kumar Jidigam; Lena Gunhaga; Jonas von Hofsten; Richard A. Lang; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BMP signaling; Placode morphogenesis; lens; retina; olfactory; otic; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : Cranial placodes are transient thickenings of the vertebrate embryonic head ectoderm that will give rise to sensory (olfactory, lens, and otic) and non-sensory (hypophyseal) components of the peripheral nervous system (PNS). In most vertebrate embryos, these four sensory placodes undergo invagination. LÄS MER

  7. 40. Structure and Function of the Retina in Children Born Extremely Preterm and in Children Born At Term

    Författare :Anna Molnar; Gerd E. Holmström; Eva K. B. Larsson; Sten O. Andréasson; Christopher J. Lyons; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; optical coherence tomography; multifocal electroretinogram; full-field electroretinography; extremely preterm children; retinopathy of prematurity; gestational age; gender; Ophtalmology; Oftalmiatrik;

    Sammanfattning : Background: Optical coherence tomography (OCT), multifocal electroretinography (mfERG) and full-field electroretinography (ffERG) give important information about retinal structure and function.Purpose: To collect normative data of macular Cirrus Spectral domain (SD)-OCT assessments and of mfERG measurements of healthy children (papers I and II).
