It has previously been demonstrated that chronic low-dose solar-simulated ultraviolet (UV) radiation can induce both local and systemic immunosuppression as well as tolerance to a topically applied hapten. Epidermal cells from UV-irradiated mice inhibit spontaneous regression of tumours indicating that UV-induced immunosuppression is likely to permit ...

The effects of UVA on the skin are well documented in the literature. Sunscreens were originally developed to protect against erythema and consequently against UVB. Even today, most sunscreens on the market provide much higher UVB than UVA protection.

Although UVA radiation was considered to be benign as a factor that could contribute to cataract formation, the studies briefly summarized herein show that UVA may provide the more damaging radiant energy involved in the formation of human cataract. Of the UVA impinging onto the eye from sunlight, a sufficient dose does reach into the lens to enhance ...

Comparison of UVA- and UVA/riboflavin-induced growth inhibition of Acanthamoeba Castellanii
Graefe's Archive for Clinical and Experimental Ophthalmology, 2012To investigate whether ultraviolet light (UVA) at 365 nm can inhibit/eliminate Acanthamoeba growth and if riboflavin would potentiate such an association.Acanthamoeba castellanii in a fluid medium with a concentration of approximately 1.7 × 10(4) protozoa/ml were prepared with (0.01 %) and without riboflavin.

UVA absorption and photostability of coumarins
Photochemical & Photobiological Sciences, 2010Various substituted 4-methylcoumarin derivatives were synthesized in order to obtain photostable derivatives with UVA absorption property. It was found that substitution positions affected maximum absorption wavelength, whereas types of substituents, whether hydroxy or alkoxy groups, caused no significant effect.

Unravelling UVA-induced mutagenesis
Photochemical & Photobiological Sciences, 2012Ultraviolet A (UVA) radiation represents more than 90% of the solar UV radiation reaching Earth's surface. Exposure to solar UV radiation is a major risk in the occurrence of non-melanoma skin cancer. Whole genome sequencing data of melanoma tumors recently obtained makes it possible also to definitively associate malignant melanoma with sunlight ...

UVA‐1 as a treatment for scleredema
Photodermatology, Photoimmunology & Photomedicine, 2004Scleredema is a rare disease that is difficult to treat. Many therapies have been tried with varied and somewhat inconsistent results. Here we report two cases of scleredema successfully treated with low‐dose UVA‐1.

UVA-induced melanocytic lesions
British Journal of Dermatology, 1987The occurrence of melanocytic lesions following PUVA therapy is well documented. We describe a patient who developed similar lesions after cosmetic use of a home sun-bed without psoralen administration. Histological examination showed increased numbers of large and sometimes atypical melanocytes, which may theoretically act as precursors for melanoma.

Evaluating the UVA protection of sunscreens
Journal of the American Academy of Dermatology, 1989Because the protection factor of sunscreens concerns only UVB protection, usually nothing is known about the protection offered in the UVA range. Using different methods, we compared six commercially available sunscreens to determine the UVA protection factor and, thus, to select the most appropriate sunscreen.
