The larvicidal effects of the essential oils extracted from the leaves of Cryptomeria japonica at different ages (58, 42, and 26 years old) against 2 mosquito species, Aedes aegypti and Aedes albopictus, were studied. The analysis of major constituents of these essential oils was also investigated. Results obtained from the larvicidal tests, using essential(More)
The high-affinity receptor for immunoglobulin G, Fc gamma RI (FCGR1), is encoded by a family of three genes within humans that share over 98% of DNA sequence homology. Efforts to define the location of the FCGR1 genes within chromosome 1 have been made to determine if they are tightly linked to the five other FCGR genes present at 1q23. Our results,(More)
A human x Chinese hamster (CH) somatic cell hybrid subclone deficient in HPRT and containing only human chromosome 18 was irradiated with 7000 rad and fused to a thymidine kinase deficient CH cell line. Radiation-rescued hybrid cell lines, selected in HAT medium, were analyzed for human DNA with human interspersed-repeat sequence primers. Size and number of(More)
In this study, the antifungal activities of cinnamaldehyde and eugenol congeners against white-rot fungus Lenzites betulina and brown-rot fungus Laetiporus sulphureus were evaluated and the relationships between the antifungal activity and the chemical structures were also examined. Results from antifungal tests revealed that cinnamaldehyde, alpha-methyl(More)
A yeast artificial chromosome (YAC) library was constructed from a somatic cell hybrid line in which the human chromosome content had been reduced by repeated subcloning to one or two copies of chromosome 18. Screening of 4700 primary yeast transformants generated 74 clones containing a YAC with a human DNA insert averaging 190 kb in size. The human YACs(More)
The effects of long-term reforestation on soil microbial communities and biomass are poorly understood. This study was conducted on two coniferous plantations: Cunninghamia konishii Hayata, planted 40 years ago (CONIF-40), and Calocedrus formosana (Florin) Florin, planted 80 years ago (CONIF-80). An adjacent natural broadleaf forest (BROAD-Nat) was used as(More)
Fifty-six chromosome 18-specific yeast artificial chromosomes (YAC) were isolated from a human monochromosomal somatic cell hybrid DNA library. Fluorescence in situ hybridization revealed that the clones were evenly distributed throughout the chromosome. The clones, with an average insert size of 250 kb, cover about 18% of the euchromatic part of chromosome(More)
