  1. 1. Retinal Transplants: Growth Differentiation Integration Organization and Survival

    Detta är en avhandling från Department of Ophthalmology, Lund University

    Författare :Rajesh Kumar Sharma; Lund University.; Lunds universitet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal degeneration; Retinal transplants; retinal development; treatment; connections; proliferation; survival; Ophtalmology; Oftalmologi;

    Sammanfattning : The goal of the study was to get a better understanding of factors controlling the growth, differen-tia-tion, integration, organization and survival of retinal transplants, with the long-term view of eventually developing retinal transplantation into a clinically useful procedure for treating degenerative retinal disorders such as retinitis pigmentosa. Embryonic day 15 rabbit retinas were transplanted into adult rabbit eyes and were allowed to survive for various times. LÄS MER

  2. 2. Experimental porcine models of retinal ischemia

    Detta är en avhandling från Ophthalmology (Lund), Lund University

    Författare :Håkan Morén; Lund University.; Lunds universitet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal ischemia; animal model; multifocal electroretinography; intraarterial coiling; retinal vasculature;

    Sammanfattning : Retinal ischaemia resulting from e.g. diabetes, vein thrombosis or arterial occlusion, is one of the major causes of visual impairment and blindness. Although new methods of treatment are being developed, there is still a need for more effective pharmacological forms of treatment. LÄS MER

  3. 3. Stem cell function and organ development analysis of Lhx2 function in hematopoietic stem cells and eye development

    Detta är en avhandling från Umeå : Umeå university

    Författare :Lina Dahl; Umeå universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Molecular medicine genetics and pathology ; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; Molecular Medicine;

    Sammanfattning : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. LÄS MER

  4. 4. Development of photoreceptor organs in teleosts, Molecular and immunocytochemical studies

    Detta är en avhandling från Department of Zoology, Lund University

    Författare :Johan Forsell; Lund University.; Lunds universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fish; opsin; extraretinal; retina; Development; pineal organ; Zoology; Zoologi;

    Sammanfattning : Many vertebrate animals are known to have multiple sites for photoreception that are not involved in vision. Extraretinal photoreception is indicated to play a crucial role in early development, physiology and behavior, as well as in later biological processes. LÄS MER

  5. 5. Retinal morphology and function in prematurely-born children at school age

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Hanna Åkerblom; Uppsala universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinopathy of prematurity; Prematurity; Retinal development; OCT; Fullfield ERG; Multifocal ERG; Ophtalmology; Oftalmiatrik;

    Sammanfattning : Preterm birth may lead to complications during the neonatal period that can cause visual dysfunctions. Retinopathy of prematurity (ROP) and neurological complications are well known reasons for visual dysfunctions, but preterm children with no or only mild ROP and no evident neurological problems may also be affected visually when they grow up.
