Response of plasma-25-hydroxyvitamin D to ultraviolet irradiation in long-stay geriatric patients
Lancet (London, England)
|September 23, 1978
Abstract:
The response of plasma-25-hydroxyvitamin D (25[OH]D) to different exposures to ultraviolet irradiation has been studied in patients in long-stay geriatric wards. Increases sufficient to bring the plasma-25(OH)D into the normal range may be obtained with doses less than those required to produce erythema. The provision of such background irradiation may be a suitable method of preventing vitamin-D deficiency in elderly subjects who receive very little exposure to sunlight.

01:35Mutations
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
