Experimental induction of freckles by ultraviolet-B

British Journal of Dermatology, 1982
Freckles were induced experimentally by single exposures of lower back skin to ultraviolet radiation. The minimal freckling dose was between 6 and 10 times the minimal erythema dose. Repeated less intense exposures did not induce freckles. Freckles could be induced only in subjects with natural freckles on exposed skin.

Ultraviolet-B Lethal Damage on Pseudomonas aeruginosa

Current Microbiology, 1996
Pseudomonas aeruginosa has shown an increased sensitivity compared with that of Escherichia coli and Enterobacter cloacae, when they were exposed to 0.4 kJ/m2 of ultraviolet-B radiation. The rapid decay in cell viability observed in Pseudomonas aeruginosa after the irradiation was influenced by factors such as culture media and the presence of ...

Ultraviolet B induces mast cell apoptosis: a hypothetical mechanism of ultraviolet B treatment for uraemic pruritus

Medical Hypotheses, 2002
The pathogenesis of uraemic pruritus is unclear, although there is some evidence that an increased number of skin-infiltrating mast cells may play a role. Ultraviolet B reduces itchy sensation of uraemic patients by leading to depletion of cutaneous mast cells.

Ultraviolet B Radiation: The Vitamin D Connection

2017
Vitamin D is known as the sunshine vitamin. During exposure to sunlight the skin transforms 7-dehydrocholesterol into vitamin D3. Throughout evolution vitamin D3 has played a pivotal role in the evolution of vertebrates. Vitamin D is not only critically important for bone health but has a multitude of other biologic functions to help reduce chronic ...
