Narrowband ultraviolet B phototherapy is the "standard" phototherapy for atopic eczema; ultraviolet A1 is sometimes used but is not a widely available treatment. We do not know the most im...
There is a growing incidence of sepsis and septic shock in people after surgery, for which there may be several reasons: more elderly people and more severe illnesses are entering operati...
Hand and foot skin diseases, such as dermatitis and psoriasis, that do not respond to topical creams can be treated with ultraviolet light therapy. Topical psoralen plus ultraviolet A (PU...
This study is a first-in-man clinical trial using fiber optically delivered ultraviolet light for reducing viable bacteria within indwelling tunneled dialysis catheters.
RATIONALE: Ultraviolet light therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells. It is not yet known whether ultraviolet light therapy is more ...
Although the ray-finned fishes are named for their bony, segmented lepidotrichia (fin rays), we are only beginning to understand the morphological and functional diversity of this key vertebrate struc...
Topical agents used in combination with phototherapy or photochemotherapy may have both blocking or enhancing effects in ultraviolet rays.
The enhancement of light-matter interaction for monolayer graphene is of great importance on many photonic and optoelectronic applications. With the aim of perfect ultraviolet trapping on monolayer gr...
Light and hormones tightly regulate plant growth and development by both synergistic and antagonistic actions. In the current issue of Developmental Cell, Liang et al. (2018) uncover how the UV-B pho...
The diffusive paradigm for the transport of Galactic cosmic rays is central to our understanding of the origin of these high energy particles. However, it is worth recalling that the normalization, en...
That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
A rare, pigmentary, and atrophic autosomal recessive disease. It is manifested as an extreme photosensitivity to ULTRAVIOLET RAYS as the result of a deficiency in the enzyme that permits excisional repair of ultraviolet-damaged DNA.
The use of ultraviolet electromagnetic radiation in the treatment of disease, usually of the skin. This is the part of the sun's spectrum that causes sunburn and tanning. Ultraviolet A, used in PUVA, is closer to visible light and less damaging than Ultraviolet B, which is ionizing.
Penetrating electromagnetic radiation emitted when the inner orbital electrons of an atom are excited and release radiant energy. X-ray wavelengths range from 1 pm to 10 nm. Hard X-rays are the higher energy, shorter wavelength X-rays. Soft x-rays or Grenz rays are less energetic and longer in wavelength. The short wavelength end of the X-ray spectrum overlaps the GAMMA RAYS wavelength range. The distinction between gamma rays and X-rays is based on their radiation source.
Exposing oneself to SUNLIGHT or ULTRAVIOLET RAYS.
