Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.

Depth of DNA photodamage in human corneas exposed to 222 nm or 254 nm UV

Photochemistry and Photobiology, EarlyView.
Representative confocal 3D image of a section of a human cornea showing nuclei in blue (Hoechst 33342) and green, which was assigned to cells exhibiting Alexa555 conjugated to anti‐CPD antibody. The depth of photodamage was measured in Z‐stacks of the human corneal epithelium after exposure of the anterior surface to 50 or 100 mJ/cm2 at 222 or 254 nm ...

Long term restoration of human corneal surface with autologous corneal epithelium generated by serial cultivation of limbal epithelial cells.

, 1997
BACKGROUND: Complete loss of the corneal-limbal epithelium leads to re-epithelialisation by bulbar conjunctival cells. Since conjunctival and corneal-limbal epithelial cells represent two different cell lines, this conjunctival healing of the cornea is ...

Human ocular‐discomfort‐free thresholds for 222 nm Far‐UVC irradiation: A prospective interventional study

Photochemistry and Photobiology, EarlyView.
Eye discomfort induced by 222 nm far‐UVC irradiation is significantly correlated with both irradiance and radiant exposure dose. The red circles indicate conditions with significant differences in the number of eye discomfort compared to the control group (blue circles), while the green circles indicate conditions with no difference from the control ...

Early oxidation‐related changes in aqueous humor following eye exposure to ultraviolet‐A radiation

Photochemistry and Photobiology, EarlyView.
UVA exposure induces early oxidative alterations in the aqueous humor, disrupting its antioxidant balance. Levels of ascorbic acid, reduced glutathione (GSH), and the GSH/GSSG ratio decrease, while oxidized glutathione (GSSG), S‐glutathionylated proteins (PSSG), and malondialdehyde (MDA), a lipid peroxidation by‐product, increase.

Reviewing the benefits and clinical outcomes of oral fibroblasts over mesenchymal stem cells for repairing periodontal defects during or after orthodontic tooth movement

Periodontology 2000, EarlyView.
Abstract Orthodontic therapy applies forces to teeth, causing an inflammatory reaction in the periodontal ligament. This is repaired by remodeling of the periodontium, allowing tooth displacement. Although orthodontic therapy is mostly initiated during childhood and adolescence, the number of adults seeking this treatment is increasing as our society's
