We investigated the roles of fliF, fliS, flhB, fliQ, fliG, and fliI of Helicobacter pylori, predicted by homology to encode structural components of the flagellar basal body and export apparatus. Mutation of these genes resulted in nonmotile, nonflagellate strains. Western blot analysis showed that all the mutants had considerably reduced levels of both flagellin subunits and of FlgE, the flage...

Bidirectional typing combines two modes of typing: type checking, which checks that a program satisfies known type, and synthesis, determines from the program. Using checking enables bidirectional to support features for inference is undecidable; using synthesis avoid large annotation burden explicitly typed languages. In addition, improves error locality. We highlight design principles underli...

objective(s):this study aims at exploring cytotoxic activity of different peptides derived from vsvg protein against mcf-7 and mda-mb-231 breast cancer cell lines and human embryonic kidney normal cell (hek 293).    materials and methods: the anticp web server was used to predict anticancer peptides. the cytotoxic activity of peptides with high score (p26, p7) and low score (p19) was examined b...

in determination of particular types of coagulate positive staphylococci (staphylococcus aurous) causing different diseases, especially hospital sepsis and food poisonings; 186 strains of coagulase positive staphylococci from different provinces in iran were phage typed. because of various sources of the strains, the results had some differences, as 15.8 percent or 15 strains separated from chi...
