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

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.

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.

Effects of the ultraviolet-B radiation (UV-B) on conifers: a review
Environmental Pollution, 1998The current knowledge on conifer responses to enhanced ultraviolet-B (UV-B) radiation is mainly based on greenhouse or growth chamber experiments of one growing season in duration. However, the biomass losses observed in greenhouses do not occur in field-grown trees in their natural habitats.

Strategies of ultraviolet-B protection in microscopic algae
Physiologia Plantarum, 1997Different species of microalgae show a wide range of susceptibility to ultraviolet‐B (UV‐B) radiation. To identify factors responsible for the UV‐B tolerance of some of the algae, we compared 8 species that are highly tolerant to UV‐B to 8 species that are highly susceptible. The tolerant species contained substantial amounts of an acetolysis‐resistant

A Discussion on astronomy in the ultraviolet - The ultraviolet spectrum of B-type supergiants
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1975Abstract The broad, steep-sided absorption lines in B-type supergiant spectra are stronger than the absorption lines in main-sequence stars. In addition to lines from the second, third and fourth spectra of the light elements and the metals there is a broad, pointed feature at 1720 A which has constant strength in the B-type ...

Influence of ultraviolet A on scheduled and unscheduled DNA synthesis by ultraviolet B.
Photodermatology, photoimmunology & photomedicine, 1992After irradiating mouse epidermis in vivo with ultraviolet radiation (UV), autoradiography using 3H-thymidine was performed to study the effects of UV on scheduled and unscheduled DNA synthesis during a 7 day-period. Suppression of scheduled DNA synthesis by 100 mJ/cm2 of UVB was continued for about 24 h and induction of unscheduled DNA synthesis by ...
