Epidemiologic evidence supporting a protective role of calcium and vitamin D in colorectal carcinogenesis has been accumulating in Western populations, but it is limited in Asian populations, whose intake of calcium is relatively low. We investigated the association of intakes of these nutrients with colorectal cancer risk in Japanese. Study subjects were participants of a large-scale case-cont...
Extended exposure to sunlight may give rise to chemical and physical damages of human hairs. In this work, we report a novel method for non-destructive quantification of hair photodamage via multispectral imaging (MSI) technology. We show that the multispectral reflectance value in near-infrared region has a strong correlation with hair photodamage. More specifically, the hair segments with lon...
STUDY OBJECTIVES The aim was to test whether cataract is associated with higher lifetime exposure to sunlight, and whether antioxidants protect against cataract. DESIGN This was a cross sectional survey of eye disease, with assessment of antioxidant status in a subgroup. SETTING Hong Kong fishing communities in 1989. PARTICIPANTS 685 men and women aged 55 to 74 years old were included in ...
Liver inflammation contributes towards the pathology of non-alcoholic fatty liver disease (NAFLD). Here we discuss how skin exposure to sunlight may suppress liver inflammation and the severity of NAFLD. Following exposure to sunlight-derived ultraviolet radiation (UVR), the skin releases anti-inflammatory mediators such as vitamin D and nitric oxide. Animal modeling studies suggest that exposu...
Photodegradation effect to natural plant waste under solar irradiation was investigated. Five plants namely, Averrhoe Bilimbi, Eugenia Clavifora, Elaies Guineensis, Terminalia cattapa and Clidemia hirta were selected from all over the states. Main purpose of this research study stability dye in presence sunlight radiation for future cell applications. FTIR UV-Vis absorption used investigate opt...
Vitamin D is synthesised in the skin during exposure to sunlight. The fundamental roles of vitamin D are the regulation of calcium and phosphate metabolism and bone mineralisation. Low vitamin D levels in athletes may adversely affect their exercise capabilities. The aim of our study was to investigate changes in serum levels of 25(OH)D3, calcium and bone turnover markers in football players in...
INTRODUCTION: Vitamin D deficiency rickets (VDDR) is a term applied to the failure of mineralization of growing bone or osteoid tissue which could be due to either inadequate direct exposure to ultraviolet rays in sunlight or to inadequate intake of vitamin D or both (1,2,3) . The vitamin D content of human milk is low (approximately 22 IU/L). However, among most breast-fed infants, the combin...
Recreational sun exposure accounts for a large number of acute and chronic dermatological diseases, including skin cancer. This study aimed at estimating the one-year prevalence of sun exposure and skin health-associated knowledge and attitudes among Austrian citizens. The population-based UVSkinRisk survey investigated a representative sample of Austrian adults using a structured questionnaire...
