Sunlight-induced anthocyanin pigmentation in maize vegetative tissues
cyanin formation have highlighted that multiple photoreceptors, such as phytochrome, blue/UV-A photoreceptor Although, in maize, sunlight-regulated anthocyanin and UV-B photoreceptor mediate the light action (Beggs formation in vegetative tissues is observed only in the and Wellmann, 1985; Beggs et al., 1986). It is assumed cultivars harbouring homozygous recessive pl loci, the that these photo...
متن کاملNutritional protection against skin damage from sunlight.
The concept of systemic photoprotection by dietary means is gaining momentum. Skin is continuously exposed to ultraviolet (UV) radiation, the major cause of skin disorders such as sunburn, photodamage, and nonmelanoma skin cancer. Most of the erythemal annual UV dose is encountered under nonvacation conditions, when no sunscreen is applied. In the absence of topically added compounds, skin prot...

متن کاملSunlight exposure, pigmentation factors, and risk of nonmelanocytic skin cancer. II. Squamous cell carcinoma.
INTRODUCTION AND DESIGN Squamous cell carcinoma of the skin (SCC), a common cancer in white populations, is related to sunshine exposure; however, relatively little information is available on how timing and character of exposure affect the relationship. The purpose of this study was to investigate the nature of the relationship of SCC to individual solar UV exposure after control for phenotype...
متن کاملSunlight, cholesterol and coronary heart disease.
We investigated the relationship between geography and incidence of coronary heart disease, looking at deficiency of sunlight and thus of vitamin D as a factor that might influence susceptibility and thus disease incidence. Sunlight deficiency could increase blood cholesterol by allowing squalene metabolism to progress to cholesterol synthesis rather than to vitamin D synthesis as would occur w...
