  1. 1. Control of early development of the lens and the retina

    Författare :Tanushree Pandit; Lena Gunhaga; Paola Bovolenta; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lens; retina; BMP; FGF; chick; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : The nervous system is composed of two separate compartments, the central and the peripheral nervous system. The peripheral nervous system (PNS) composed mainly of sensory organs transmits sensory information to the central nervous system (CNS) comprising the brain and the spinal cord. LÄS MER

  3. 2. Fish Lenses : Anatomy and Optics

    Författare :Tomasz M Kozłowski; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plasticity; Development; Cellular structure; Lens fiber cells; Modeling; Laser Scanning; Schlieren photography; Fast Fourier Transform FFT ;

    Sammanfattning : I have investigated some of the biological regulatory mechanisms governing the development of crystalline lenses. I used fish as model animals because they possess optically interesting lenses, while the geometrical simplicity of fish lenses allows for studies that are difficult or impossible with the lenses of other animals.

  4. 3. 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

  5. 4. Ultraviolet radiation cataract

    Författare :Konstantin Galichanin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :lens;

    Sammanfattning : Cataract is the leading cause of blindness in the world. Epidemiological and experimental evidence supports a link between mid-range ultraviolet radiation (UVR-B) exposure and the development of cataract. LÄS MER

  7. 5. Forkhead Genes in Mammalian Development

    Författare :Henrik Landgren; Göteborgs universitet; []
    Nyckelord :Development; Forkhead;

    Sammanfattning : This thesis concerns aspects of Forkhead gene biology and it’s relation to mammalian development. Genes from three subclasses are discussed, Foxj3, Foxf1 and f2, and Foxe3. LÄS MER
