  1. 1. Evolution of eyes: Pax, gene duplications & morphology

    Författare :Karin Nordström; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; animal morphology; Djurs anatomi och morfologi; Animal anatomy; tetraploidization; planula; phototransduction; pax; paired domain; mutagenesis; cnidaria; eye evolution;

    Sammanfattning : During the course of evolution animal complexity and diversity is generated. The last couple of years it has become increasingly clear that morphologically diverse animals share a great deal of their genomic contents, and it must be the expression of regulatory genes in new setting, rather than the generation of new genes, that are fundamental for the generation of diversity.

  3. 2. Evolution of Vertebrate Endocrine and Neuronal Gene Families : Focus on Pituitary and Retina

    Författare :Daniel Ocampo Daza; Dan Larhammar; Marc Robinson-Rechavi; Uppsala universitet; []
    Nyckelord :phylogenetics; evolution; molecular evolution; gene family evolution; genome duplication; gene duplication; oxytocin receptor; vasopressin receptor; visual opsin; transducin; growth hormone; prolactin; somatolactin; growth hormone receptor; prolactin receptor; somatostatin receptor; SSTR; IGFBP; evolution; molekylär evolution; fylogeni;

    Sammanfattning : The duplication of genes followed by selection is perhaps the most prominent way in which molecular biological systems gain multiplicity, diversity and functional complexity in evolution. Whole genome duplications (WGDs) therefore have the potential of generating an extraordinary amount of evolutionary innovation. LÄS MER

  4. 3. Studies into The Mechanisms of Neurodegeneration and Neuroprotection in Rd1 Mouse Retina

    Författare :Seifollah Azadi; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signaling pathway ; Ophtalmology; neurotrophic factors ; Oftalmologi; retina degeneration ;

    Sammanfattning : Retinitis Pigmentosa (RP) is a group of uncured retinal diseases with the world wide incidence of about 1/3500. In spite of the huge efforts in past years, the mechanisms underlying this type of hereditary blindness has not been elucidated and nor any effective treatment available. LÄS MER

  5. 4. Selective wavelength pupillometry to evaluate outer and inner retinal photoreception

    Författare :Aki Kawasaki; Fatima Pedrosa Domellöf; Bertil Lindblom; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pupil; pupil light reflex; melanopsin; photoreceptor; intrinsically photosensitive retinal ganglion cell; oftalmiatrik; Ophtalmology;

    Sammanfattning : PurposeIntrinsically photosensitive retinal ganglion cells (ipRGCs) express a unique photopigment called melanopsin. Capable of direct phototransduction, the ipRGCs are also influenced by rods and cones via synaptic inputs. LÄS MER
