Measurements of the Diffuse Ultraviolet Radiation [PDF]
Symposium - International Astronomical Union, 1989 We have used the imaging instrumentation on the Dynamics Explorer 1 (DE) satellite to measure the intensity of the diffuse ultraviolet (UV) radiation on two great circles about the sky. We find that the isotropic component of the diffuse UV radiation (possibly of extragalactic origin) has an intensity of 530 ±80 units (a unit is one photon cm−2 s−1 sr ...

Measurements of Solar Ultraviolet Radiation Exposure at Work and at Leisure in Danish Workers
Photochemistry and Photobiology, 2018 Exposure to solar ultraviolet radiation is the main cause of skin cancer and may well present an occupational health and safety problem. In Denmark, skin cancer is a common disease in the general population, but detailed data on solar ultraviolet ...

Ozone and ultraviolet radiation [PDF]
, 1997 Imagine if the earth’s protective atmosphere did not exist and the earth was subjected to the harmful ultraviolet energy from the sun. Life as we know would not exist.

Molecular Oncology, EarlyView.This study identifies nuclear YB‐1 S102 phosphorylation as a marker associated with KRAS and FBXW7 mutations in colorectal cancer. Mutated KRAS correlates specifically with nuclear, not cytoplasmic, S102 YB‐1. These findings provide the first ex vivo evidence of this link in CRC and suggest future studies should assess the prognostic and therapeutic ...

Effects of Short-term Low Intensity Laser and Ultraviolet Radiation on Embryos of Daphnia Magna [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2011 Short-term impact of the low intensity electromagnetic radiation on in vitro growing Daphnia magna Straus embryos was studied. Embryos were exposed to laser radiation (633 nm, 0.05 mW/cm2) and ultraviolet radiation (365 nm, 0.16 mW/cm2) separately as ...

Ultraviolet B but not Ultraviolet A Radiation Initiates Melanoma [PDF]
Cancer Research, 2004 Abstract Cutaneous malignant melanoma is one of the fastest increasing cancers with an incidence that has more than doubled in the last 25 years. Sunlight exposure is strongly implicated in the etiology of cutaneous malignant melanoma and the UV portion of the sunlight spectrum is considered responsible. Data are, however, conflicting on

Molecular Oncology, EarlyView.Raphin‐1 reduces the survival of PED‐DHGG cells and enhances their radiation sensitivity through both PeIF2α‐dependent and PeIF2α‐independent mechanisms. Raphin‐1 sustains elevated levels of PeIF2α, contributing to its PeIF2α‐dependent effects. Additionally, raphin‐1 interacts with CReP to mediate a separate radiosensitizing pathway that operates ...

Sunlight-induced Painful Skin (Sun Pain): A New Differential Diagnosis in Photodermatology
Acta Dermato-Venereologica, 2021 Photodermatoses are characterized by the development of skin eruptions following exposure to ultraviolet radiation or visible light. We report here the clinical findings and results of laboratory investigations and phototesting of 6 patients who ...

Ultraviolet Background Radiation
Annual Review of Astronomy and Astrophysics, 1973 The results are reported of observations in narrow bands centered on 1115, 1425, and 1446 A of the flux from an empty high-galactic-latitude region and from several stars. The observations had been obtained with the aid of three ultraviolet-sensitive Geiger counters which were carried on an Aerobee-150 rocket launched from the White Sands missile ...
