dna sequencing is the most conclusive method for emm (m protein gene) typing of streptococcus pyogenes. this method is not a feasible approach in developing countries where streptococcal infection is widespread among adults and children. alternatively the pcr-rflp has the potential for rapid screening of different types of s. pyogenes. to document the emm type distribution of s. pyogenes in a g...

background: aspergillus species are associated with allergic bronchopulmonary disease, mycotic keratitis, otomycosis, na­sal sinusitis and invasive infection. in this study, we developed a pcr-single strand confomational polymorphism method to identify the most common aspergillus species and we showed some advantages of this method comparing a pcr-restric­tion fragment length polymorphism with ...

BACKGROUND The mechanism of cytotoxicity induction by flavonoids has been studied by many investigators, but their tumor specificity is not clear. To address this point, 10 licorice flavonoids were subjected to quantitative structure-activity relationship (QASR) analysis with cytotoxicity assay with four human oral carcinoma and three normal cell lines. MATERIALS AND METHODS Cytotoxicity was ...

different methods have been proposed for finding the non-negative solution of fully fuzzy linear system (ffls) i.e. fuzzy linear system with fuzzy coefficients involving fuzzy variables. to the best of our knowledge, there is no method in the literature for finding the non-negative solution of a ffls without any restriction on the coefficient matrix. in this paper a new computational method is ...
