Photochemoprevention of ultraviolet B signaling and photocarcinogenesis
Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 2005Exposure to solar radiation, particularly its ultraviolet (UV) B component, has a variety of harmful effects on human health. Some of these effects include sunburn cell formation, basal and squamous cell cancers, melanoma, cataracts, photoaging of the skin, and immune suppression. Amongst these various adverse effects of UV radiation, skin cancer is of

Keratopathy after ultraviolet B phototherapy
Wiener klinische Wochenschrift, 2005Atopic dermatitis is the most common chronic inflammatory skin disease among children in industrialized countries. The prevalence is recorded to be up to 20% in children. Phototherapy with ultraviolet B (UVB) is an effective form of treatment with a low complication rate. Here we report on a patient with atopic dermatitis who underwent UVB treatment to

Ultraviolet-B Damages Corneal Endothelium
Optometry and Vision Science, 1984Direct in vivo observation of acute ultraviolet (UV)-induced corneal endothelial damage is not possible due to the more severe damage produced in the epithelium. In order to quantify damage and evaluate endothelial recovery an indirect method was used.

Ultraviolet-B Effects on Ocular Tissues
Biochemical and Biophysical Research Communications, 1995The enhancement of UVB on the surface of the earth due to stratospheric ozone depletion may increase the risk of photochemically induced cataract. In this study, changes in the content of certain biological parameters were used as a marker to study ocular toxicity.

Ultraviolet-B Radiation and Photosynthesis
2006It has long been recognized that declining levels of stratospheric ozone and the subsequent increase in ultraviolet (UV)-B radiation may deleteriously affect plant photosynthesis. However, there is a wide range of susceptibility in the photosynthetic apparatus with respect to increasing UV-B radiation.

Experimental induction of freckles by ultraviolet-B
British Journal of Dermatology, 1982Freckles were induced experimentally by single exposures of lower back skin to ultraviolet radiation. The minimal freckling dose was between 6 and 10 times the minimal erythema dose. Repeated less intense exposures did not induce freckles. Freckles could be induced only in subjects with natural freckles on exposed skin.

Eye protection for ultraviolet B phototherapy and psoralen ultraviolet A patients
Acta Ophthalmologica, 2010Abstract Purpose We tested eye protection used for phototherapy patients. The study also established current practice concerning eye protection in a sample of UK phototherapy units. Methods The ultraviolet (UV) transmission spectra of 30 'UV protective' contact lenses were measured at 5 nm intervals between 290 and 400 nm.

A Survey of Ultraviolet-B Radiation in Forests
The Journal of Ecology, 19941 Ultraviolet-B radiation (UV-B, 280-320 nm) was surveyed in a mixed deciduous forest in Maryland, USA, using a Robertson-Berger meter. A smaller number of comparable measurements were made in closed-canopy forests in Chile, Panama, and Washington State, USA, and under two canopies recently disturbed by hurricanes, in Virginia, USA, and Mexico ...

Medical Hypotheses, 2002
The pathogenesis of uraemic pruritus is unclear, although there is some evidence that an increased number of skin-infiltrating mast cells may play a role. Ultraviolet B reduces itchy sensation of uraemic patients by leading to depletion of cutaneous mast cells.

Photoadaptation to ultraviolet B TL01 in psoriatic patients
Journal of the European Academy of Dermatology and Venereology, 2020AbstractBackgroundIn the biologic era, narrow‐band ultraviolet B (NB‐UVB) phototherapy still remains a valuable, effective, inexpensive, safe anti‐psoriatic treatment. Patients can lose response to NB‐UVB over time due to photoadaptation. This phenomenon is the tendency of the skin to respond to ultraviolet (UV) exposure by undergoing changes that may ...
