  2. 16. α1- and α2-Adrenoceptors in the Eye : Pharmacological and Functional Characterization

    Author : Anna Wikberg-Matsson; Thomas Mittag; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; α1-adrenoceptor subtypes; α2-adrenoceptor subtypes; iris; ciliary body; choroid; retina; ciliary artery; Neurovetenskap; Neurology; Neurologi; Ophtalmology; oftalmiatrik;

    Abstract : α1- and α2-Adrenoceptors are involved in various physiological events in the eye: blood flow regulation, aqueous humor dynamics and pupil regulation. The α1- and α2-adrenoceptors can be further subdivided into six subtypes (α1A, α1B, α1D, α2A , α2B, and α2C ). READ MORE

  4. 17. Experimental Neuroretinal Transplantation

    Author : Fredrik Ghosh; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transplant; Retinal degeneration; Retina; Rabbit; Neural development; Immunohistochemistry; MHC; Ultrastructure; Vitrectomy; Ophtalmology; Oftalmologi;

    Abstract : Embryonic full-thickness rabbit neuroretinal sheets were transplanted to the subretinal space of adult hosts. This was accomplished by using a new transplantation technique involving vitrectomy and retinotomy. The grafts were followed from 10 to 306 days after surgery, and were then examined by different histological techniques. READ MORE

  5. 18. Neurotrophic Factor Receptors in the Normal and Injured Visual System : Focus on Retinal Ganglion Cells

    Author : Niclas Lindqvist; Finn Hallböök; Anders Kvanta; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; cell survival; gene expression; neurotrophic factor; receptor; retina; visual system; Neurovetenskap; Neurology; Neurologi; Developmental Neurosciences; Medicinsk utvecklings- och neurobiologi;

    Abstract : The focus of this thesis is the life and death of adult retinal ganglion cells (RGCs). RGCs are neurons that convey visual information from the retina to higher centers in the brain. READ MORE

  6. 19. Cystatin C in the Eye and in Specific Model Systems

    Author : Johan Wasselius; Lund Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; protein uptake; ciliary body; lens; cornea; retina; eye; Cystatin C; cathepsin B; Oftalmologi;

    Abstract : It is a necessity of life to make proteins, and it is an equal necessity to degrade those proteins, to eliminate dysfunctional proteins, and leave room for new ones. The processes of protein synthesis and degradation into peptides - proteolysis - have attracted a great interest during the last decades. READ MORE

  7. 20. BMP - a key signaling molecule in specification and morphogenesis of sensory structures

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

    Abstract : 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. READ MORE
