| [rapid identification of clinical yeast species by single-strand conformation polymorphism analysis of 26s rdna d1/d2 domain]. | to investigate the reliability of single-strand conformation polymorphism (sscp) analysis of 26s rdna d1/d2 domain for rapid identification of clinical yeast species and to examine the distribution of the yeast species in clinical strains from beijing. | 2009 | 19835161 |
| [evaluation of estrogenicity of sewage samples from beijing, china]. | the recombinant yeast estrogen screen (yes) was used to evaluate the estrogenic activities of sewage samples from every step of three sewage treatment plants (stps) in beijing, china. meanwhile, eight target endocrine-disrupting compounds (edcs) in corresponding sewage samples were simultaneously analyzed by gc/ms system to further elucidate the variations of their estrogenic activities. the results indicated that estrogenic activities could be considerably reduced by stps with the rate of 82.2% ... | 2009 | 20187392 |
| identification of estrogen receptor agonists in sediments from wenyu river, beijing, china. | assignment of ecological impacts of contamination to specific classes of contaminants is a prerequisite for risk assessment and remediation. in this study, the combination of polarity-based fractionation, two-hybrid yeast bioassay, and chemical analysis were used to evaluate and identify estrogen receptor agonists (er-agonists) in sediments from wenyu river, beijing, china. by bioassay, organic raw sediment extracts could induce significant estrogenicity and the bioassay-derived 17β-estradiol eq ... | 2011 | 21621810 |
| in vitro thyroid disrupting effects of organic extracts from wwtps in beijing. | it is generally known that there are many endocrine disrupting compounds (edcs) in the effluents from wastewater treatment plants (wwtps). most research has focused on the occurrence of estrogenic or androgenic activities, while ignoring that there are environmental chemicals disrupting thyroid system, which is essential for growth and development in both humans and animals. in the present work, a two-hybrid yeast assay was conducted to evaluate the removal efficiencies of agonistic or antagonis ... | 2011 | 21793411 |
