OBJECTIVES To explore whether mortality from female breast, ovarian, colon, and prostate cancer were negatively associated with exposure to sunlight. METHODS A death certificate based case-control study of mortality was conducted into five cancers: female breast, ovarian, colon, prostate, and non-melanoma skin cancer (as a positive control) to examine associations with residential and occupat...
skin cancer is the most prevalent type of cancer in most of the countries and more than 90% of cancer cases are related to ultra violet rays of the sun. therefore protective behaviors against sunlight are considered the most essential measures for skin cancer prevention. this study has been conducted to determine the frequency of protective behavior against sunlight among female students of teh...
What makes the sun shine? How does the sun produce the vast amount of energy necessary to support life on earth? These questions challenged scientists for a hundred and fifty years, beginning in the middle of the nineteenth century. Theoretical physicists battled geologists and evolutionary biologists in a heated controversy over who had the correct answer. Why was there so much fuss about this...
Further to Rose Mitchell's and Darren Savarimuthu's comments (letters June 20, July 4), I think they both need to look at why they wanted to be nurses in the first place.

To set up a reasonable crop irrigation system in the context of global climate change in Northern Xinjiang, China, reference crop evapotranspiration (ET0) was analyzed by means of spatiotemporal variations. The ET0 values from 1962 to 2010 were calculated by Penman-Monteith formula, based on meteorological data of 22 meteorological observation stations in the study area. The spatiotemporal vari...
Dr. Harold D. Appleton, a Dedicated Beginning When Dr. Harold D. Appleton took over the small, semi-regular newsletter, The Clinical Chemist, from Dr. Andre Kibrick, he “ate, drank and slept ‘The Clinical Chemist,’” according to Irving Sunshine, PhD.

Background: Some studies on Multiple Sclerosis (MS) have suggested that adequate vitamin D intake can modulate the course of MS and decreases its incidence. However, there are limited studies with conflicting findings on the relation between MS severity, its course, and vitamin D intake. Objectives: The current study aimed to compare vitamin D intake and sunlight exposure between MS phenotype...
