In May 2004, 97 of 309 (31%) and 97 of 207 (47%) school students from geographically distant areas were affected by acute gastroenteritis during excursions to neighboring hotels. The two hotels were 300 m apart, on Jeju Island, South Korea. Several strains of norovirus, including both genogroup I and genogroup II viruses, were identified in stool samples from the students and food handlers and in groundwater from the hotels. Of these several strains of norovirus, the nucleotide sequences for one strain were identical for samples from the students, food handlers, and groundwater.
The low-intensity luminescence of ZnSeix Te x with x = l% exhibits several unusual features which are attributed to the occurrence of efficient exciton self-trapping induced by Te atoms. This type of exciton localization is strikingly different from that observed in other II-VI or III-V mixed crystals.
SBRT is a feasible treatment option for women with pelvic sidewall tumors from recurrent uterine cervical cancer, especially for small recurrent tumors. However, SBRT should be used carefully in the treatment of large tumors, as the incidence of severe late toxicity increases with the size of the tumor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
