background and objectives: day-shift taxi drivers have a long duration of direct sun exposure. however, the efficiency of this occupational exposure in vitamin d synthesis has not been addressed yet. the aim of this study was to assess the vitamin d status of taxi drivers in tehran, and examine vitamin d status association with some anthropometric and circulating biomarkers. materials and metho...

background: numerous studies have assessed risk factors for multiple sclerosis (ms), but regarded to paradoxical results & specific ethnical- cultural circumstances in ahvaz, as a city in iran, this case-control study was aimed to assess some factors related to lifestyle (consumption & exposure with cigarette smoking, duration & surface of sun light exposure, exposure to pets and farm animals) ...

Background: The onset of primary progressive multiple sclerosis (PPMS) can be triggered by sun exposure and physical activity. The present study aimed to determine the risk of sun exposure and physical activity in PPMS development. Methods: The case-control study recruited PPMS cases and healthy controls from the general population from September 2019 to September 2020 in Tehran, Iran. The sel...

Objective(s) Studies have described immunomedulatory effects of sun exposure and ultraviolet radiation on infectious and neoplastic diseases. Here the effect of exposure to low potency radiation of sun on the course of leishmaniasis in mice was studied. Materials and Methods Fifteen BALB/c mice were exposed to suberythemogenic doses of sun (mean 180 mJ/cm2/day of UVB) 2 months before and 4 m...

Sun exposure in both childhood and adult life represents the main environmental risk determinant for cutaneous melanoma. However, little is known about the joint effects of sun exposure during early and later life on melanoma risk. A case-control study in Belgium, Germany and France conducted in 1991-1992 suggests that the melanoma risks attached to indicators related to sun exposure appear to ...
