The chromosomal ispA gene encoding farnesyl diphosphate synthase of Escherichia coli was disrupted by inserting a neo gene cassette. The null ispA mutants were viable. The growth yield of the mutants was 70% to 80% of that of the wild-type strain under aerobic conditions, and was almost the same as the wild-type under anaerobic conditions. The levels of(More)
The mouse apolipoprotein E gene was isolated from a genomic library by screening with a cDNA probe. DNA including apolipoprotein E gene plus segments 2.5 kilobases upstream and 0.3 kilobase downstream of the coding region was transfected into NIH3T3 cells. The cells expressed the same-size apolipoprotein E mRNA and protein as those produced by mouse(More)
Inputting query terms on a mobile terminal is frustrating because of device limitations though mobile web search is becoming popular. Query prediction is a promising approach for mobile search. In the literature, however, little attention has been paid to the first query term, though there are many reports on query expansion or second query recommendation.(More)
