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 ...
A reliable diagnostic device for free-electron lasers (FELs) is essential for both users and the evaluation of FEL sources and beamline optics. Here, we propose a compact bolometric radiometer (CBR) t...
GW170817 was the first gravitational wave detection of a binary neutron-star merger1. It was accompanied by radiation across the electromagnetic spectrum and localized2 to the galaxy NGC 4993 at a dis...
Topical agents used in combination with phototherapy or photochemotherapy may have both blocking or enhancing effects in ultraviolet rays.
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...
Free radicals and reactive oxygen species (ROS) are generated using various endogenous systems or from external sources such as exposure to different physiochemicals. Ionizing radiation damage to the ...
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.
