Sunlight-related biological effects such as skin cancer, sunburning, and synthesis of vitamin D in the body have been found to be very low in people in the midregion of Saudi Arabia. The present studies were undertaken to measure the sunburning-carcinogenic ultraviolet light (UV) radiation (UV-B) in natural sunlight in the city of Riyadh (25 degrees north latitude). The average noontime inciden...

Growing evidence suggests that environmental factors play a key role in the onset of multiple sclerosis (MS). This study was conducted to examine whether environmental factors may also be associated with the evolution of the disease. We collected data on smoking habits, sunlight exposure and diet (particularly consumption of vitamin D-rich foods) from a sample of 131 MS patients. We also measur...

BACKGROUND Some epidemiological studies reported that sunlight exposure and highvitamin D levels may decrease the morbidity and mortality related to cancer. We aimed to evaluate whether sunlight exposure has an impact on survival in patients with non small cell lung cancer. MATERIALS AND METHODS A total of 546 patients with NSCLC from two different regions (Kayseri and Adana) differing accord...

Barn Orientation The first freestall barn design criteria to consider should be the orientation of the structure. Barns with a north-south orientation are exposed to greater solar radiation than barns with an east-west orientation. Sunlight enters north-south oriented barns directly in the morning and afternoon. While afternoon sun is the most detrimental, morning sun also can affect cow behavi...

Have you ever had that gut reaction to your surroundings, some physical sensation that something isn’t quite right? Maybe a squirmy, uneasy feeling in your stomach or an acrid taste on your tongue that makes you want to leave the scene? When the nematode C. elegans encounters an offensive sensation—whether a pungent, potentially dangerous odor (such as those associated with fungal parasites), e...
