Amphibian defenses against ultraviolet‐B radiation
Evolution & Development, 2002SUMMARYAs part of an overall decline in biodiversity, amphibian populations throughout the world are disappearing. There are a number of potential causes for these declines, including those related to environmental changes such as increasing ultraviolet‐B (UV‐B) radiation due to stratospheric ozone depletion.

High Sensitivity of Tubifex for Ultraviolet-B
Biochemical and Biophysical Research Communications, 1997Phytoplankton and zooplankton serve as major food material for primary and secondary consumers in the marine food web. Although phytoplankton are primary targets to UV radiation damaging effects, we have demonstrated that stratospheric ozone depletion will affect zooplankton to contribute to inhibition in biomass production.

Langerhans cell responses to ultraviolet B radiation
Journal of Dermatological Science, 1999Skin exposure to solar radiation induces a series of characteristic changes, from the acute sunburn reaction to the development of pre-malignant and malignant tumors. The spectra of radiation within the ultraviolet B (UVB) light range (from 290 to 320 nm in wavelength) appear to cause most of the deleterious effects of solar radiation.

Solar ultraviolet‐B radiation under cloudless skies
Quarterly Journal of the Royal Meteorological Society, 1987AbstractSolar ultraviolet‐B (UVB) irradiance IB (300‐316 nm) and visible radiation IV (300‐700 nm) were measured at Sutton Bonington in the Midlands. On clear days the ratio of irradiance in the two wavebands, IB/IV, plotted against the cosine of the solar zenith angle gave a series of straight lines of the form IB/IV = x + y cos z.

Narrowband ultraviolet B radiation suppresses contact hypersensitivity
Photodermatology, Photoimmunology & Photomedicine, 2008SummaryBackground/purpose: A main mechanism responsible for the efficacy of narrowband ultraviolet (UV)B is thought to be the induction of apoptosis in pathogenetically relevant cells. Narrowband UVB therapy, however, generally induces a relatively long remission period.

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.

Mass‐Manufactural Lanthanide‐Based Ultraviolet B Microlasers
Advanced Materials, 2018AbstractLanthanide (Ln3+)‐based ultraviolet B (UVB) microlasers are highly desirable for diagnostics and phototherapy. Despite their progress, the potential applications of UVB microlasers are strongly hindered by their low optical gain, weak light confinements, and poor device repeatability.

Narrowband ultraviolet B (UVB) phototherapy in children
Clinical and Experimental Dermatology, 2006While narrowband ultraviolet B (UVB) phototherapy is a well-established treatment for a range of skin conditions in adults, there is little in the literature about its use in children and data regarding its long-term carcinogenic potential are lacking.We undertook a retrospective review of the use of narrowband UVB phototherapy in a paediatric ...

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

Narrow-band ultraviolet B phototherapy in childhood
Cutaneous and Ocular Toxicology, 2013Narrow-band ultraviolet B (UVB) has been used for skin diseases in children. However, the use of phototherapy in childhood has limited due to the possible risk of skin cancer. The aim of this study is to evaluate the efficacy and safety of the narrow-band UVB phototherapy in children for the treatment of various skin diseases.The data of the children ...
