Sunscreens, UV Radiation, and Growth of Transplanted Melanoma Cells

[Melanoma, altitude, and UV-B radiation].

BACKGROUND AND OBJECTIVES UV radiation is the main modifiable risk factor for the development of cutaneous melanoma. Many people in the Spanish province of Granada live at high altitudes and, therefore, receive high doses of UV-B radiation. The aims of this study were to assess the possible association between melanoma and altitude and to measure the daily erythemal dose at different altitudes....

Effects of UV B and UV C radiation on viability, growth, and major natural compounds of Malve neglecta L. cells . Faezeh Ghanati*, Faezeh Khatami, and Ebrahim Bemani

Callus cultures were established in vitro from leaf explants of Malva neglecta and were sub-cultured several times until a rapid-growing cell line was obtained. The calluses were exposed to different doses of ultraviolet (UV) radiation as follows: 0, 432, 864, and 1296 J/m2 for UV B and 0, 612, 1284, and 1836 J/m2 for UV C, corresponding to 0, 30, 60, and 90 min radiations, in tandem. Exposure ...

Sunscreens and melanoma: the future looks bright.

BACKGROUND Meta-analyses of observational case-control studies have demonstrated no association between sunscreen use and the development of malignant melanoma. OBJECTIVES To examine whether this observation is to be expected given the period during which the case-control studies were conducted, the sunscreens prevalent at that time, and how sunscreen is used and applied in practice. To predi...

Sunscreens in melanoma and skin cancer prevention.

UV radiation, latitude, and melanoma in US Hispanics and blacks.

BACKGROUND Little information exists on the epidemiology of melanoma and the role of solar radiation in the development of melanoma in pigmented populations. OBJECTIVE To evaluate the relationship between exposure to solar radiation and the incidence of melanoma in US Hispanics and blacks. DESIGN Population-based ecological study. SETTING State cancer registries of New York, New Jersey, I...
