In the last decade, the random amplified polymorphic DNA (RAPD) technique based on the polymerase chain reaction (PCR) has been one of the most commonly used molecular techniques to develop DNA markers. RAPD is a modification of the PCR in which a single, short and arbitrary oligonucleotide primer, able to anneal and prime at multiple locations throughout the genome, can produce a spectrum of a...

asafoetida is the dried latex exuded from the living underground rhizome or tap root of ferula assafoetida. antibacterial characteristic of asafoetida was shown using the circular zone diameter of bacterial growth inhibition by disk-diffusion method on two gram positive and three gram negative bacteria. then, the bacterial genomic dna damage, induced by f. assafoetida latex, was demonstrated us...

background and objective: formalin-fixed paraffin-embedded tissues are a valuable source of dna for molecular studies. we designed and optimized an efficient procedure for dna extraction from formalin-fixed paraffin embedded tissues. materials and methods: seventy three blocks of cervical paraffin-embedded tissues were investigated. dna was extracted using 45 minutes boiling in alkaline solutio...

Objective(s) Resistance to antimicrobial agents, particularly metronidazole and clarithromycin, is frequently observed in Helicobacter pylori and may be associated with treatment failure. This resistance rate varies according to the population studied. The aim of this study was to assess the pattern of antimicrobial resistance of H. pylori isolates from dyspeptic patients in Isfahan. Material...

DNA heterogeneity among members of the genus Brucella was demonstrated with the arbitrarily primed polymerase chain reaction (AP-PCR). Simple, reproducible genomic fingerprints from DNA of 25 different Brucella strains were generated with five arbitrarily chosen primers, alone and in pairs, with the PCR. Reaction conditions were optimized for each primer. Several DNA segments were amplified in ...
