| study of ultraviolet radiation and genotoxic effects of natural sunlight in relation to skin cancer in saudi arabia. | 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 incidence of uv-b, measured with a sunburn uv-meter, was found to be between 1.9 and 3.4 sun units/hr in the m ... | 1984 | 6370425 |
| candida dubliniensis at a university hospital in saudi arabia. | candida dubliniensis is a newly described yeast species that is a close phylogenetic relative of c. albicans. although it has been reported from different parts of the world, no detailed investigation of this species has been done in saudi arabia. the purpose of the present study was to identify c. dubliniensis isolates recovered from clinical specimens at a tertiary-care hospital in riyadh, saudi arabia, and to determine the drug susceptibility profiles of those isolates. over a period of 8 mon ... | 2003 | 12734225 |
| the yeast species causing fungemia at a university hospital in riyadh, saudi arabia, during a 10-year period. | this study is a retrospective investigation to determine the species of yeasts causing fungemia in a university hospital in saudi arabia during the years 1991-2000. a total of 189 episodes of fungemia were encountered, of which 121 (64%) occurred during 1991-1995, whereas only 68 cases (36%) were found between 1996 and 2000. overall, 50.3% episodes were due to candida albicans including five episodes of c. dubliniensis, followed by c. tropicalis (27%), c. parapsilosis (7.9%), c. glabrata (7.4%), ... | 2003 | 12950897 |
