  2. 1. Long-wave ultraviolet radiation (UVA1) and visible light : therapeutic and adverse effects in human skin

    Author : Desiree Wiegleb Edström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Ultraviolet-A; visible light; p53; p21WAF-1; bcl-2; CD34; port-wine stains; mycosis fungoides; dye laser; photodynamic therapy.;

    Abstract : We studied the effects of repetitive low-dose UVA1 radiation and visible light in normal sunshielded skin, using immunohistochemical staining for p53, p21WAF-1, bcl-2, Ki67 and cyclin A. An increased expression of Ki67 after UVA1 and visible light were observed as a sign of increased proliferation. READ MORE

    Abstract : Background: Today corneal crosslinking with ultraviolet-A photoactivation of riboflavin is an established method to halt the progression of keratoconus. In some cases, when the refractive errors are large and the visual acuity is low, conventional corneal crosslinking may not be sufficient. READ MORE

    Abstract : 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.
