Peptide nucleic acid-mediated competitive PCR clamping, which can selectively amplify mutant alleles, was developed to detect mutations in four codons (513, 516, 526, and 531) of the rpoB gene in Mycobacterium tuberculosis strains. This simple method successfully identified the mutations in all 40 of the M. tuberculosis strains tested.

Background and Objectives: The incidence of rifampin-resistant strains of Mycobacterium tuberculosis has attracted more attention than the tuberculosis infection due to laborious treatment and control. Recognizing the Mycobacterium tuberculosis genotypes involving in drug resistance via multiplex PCR, a simple and rapid genotyping method, is an emergency for better tre...

Objective: Breast lesions in childhood are mostly benign and self-limiting, the biopsy indications restricted this period. The differentiation between fibroadenomas phyllodes tumors is difficult with imaging because of their overlap initial size growth rate. Therefore, or excision may be required. Material Methods: We retrospectively reviewed data from 531 patients (404 females, 76.1%; 127 male...
