  1. 1. Neuropeptides and neurotransmitters in keratocytes : importance in corneal wound healing processes

    Författare :Marta Sloniecka; Patrik Danielson; May Griffith; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; substance P; acetylcholine; migration; proliferation; apoptosis; corneal stroma;

    Sammanfattning : Background: The cornea is the outermost transparent layer of the eye and it is responsible for the majorityof the eye’s total focusing power. Keratocytes are the resident cells of the corneal stroma and their function isto produce extracellular matrix components and to take part in corneal healing after injury, which may occurdue to trauma, infection or surgery.

  3. 2. Two New Corneal Diseases Characterized by Recurrent Erosions

    Författare :Björn Hammar; Per Fagerholm; Erik Björck; Minna Vesaluoma; Linköpings universitet; []
    Nyckelord :Cornea; Corneal Dystrophy; Dystrophia Smolandiensis; Dystrophia Helsinglandica; Recurrent Erosions; MEDICINE; MEDICIN;

    Sammanfattning : Recurrent corneal erosions are a common complication of superficial corneal wounds. They most commonly arise following a trauma, in association with various corneal dystrophies, or are idiopathic. LÄS MER

  4. 3. Corneal cellular proliferation and wound healing

    Författare :Lisha Gan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cornea; cell proliferation; wound healing; stem-cells; leukocytes; PCNA; hyaluronan; alkali injury; photorefractive keratectomy;

    Sammanfattning : Background: Cellular proliferation plays an important role in both physiological and pathological processes. Epithelial hyperplasia in the epithelium, excessive scar formation in retrocorneal membrane formation and neovascularization are examples of excessive proliferation of cornea cells. Lack of proliferative ability causes corneal degeneration. LÄS MER

  5. 4. Arachidonic acid metabolism in corneal epithelial cells : Identification of lipoxygenase isoforms

    Författare :Maria Liminga; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Cornea; cDNA cloning; lipoxygenase; liquid chromatography-mass spectrometry; organ culture; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : The metabolism of arachidonic acid in the human cornea was investigated and compared with the metabolism in cattle and primates. All three species showed significant arachidonic acid metabolism inthe epithelium, whereas the activity in the stroma and the endothelium was low or undetectable. LÄS MER

  7. 5. Advanced surgeries, medicines and materials for corneal regeneration

    Författare :Maria Xeroudaki; Neil Lagali; Beatrice Bourghardt Peebo; Per Fagerholm; Stefan Schrader; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Corneal transplantation is often the only treatment option in cases of corneal blindness, with the main challenges being the scarcity of human donors, risk for graft failure and suboptimal visual outcome due to suture-related issues. Alternative therapies are sought that either address the above transplantation issues directly or stimulate the cornea’s repair mechanism and regenerative properties to restore transparency without the need for transplantation.
