Since its invention in 1985 the polymerase chain reaction (PCR) has become a well-established method for amplification and detection of segments of double-stranded DNA. Incorporation of fluorogenic probe or DNA intercalating dyes (such as SYBR Green) into the PCR mixture allowed real-time reaction monitoring and extraction of quantitative information (qPCR). Probes with different excitation spe...
Staphylococcus epidermidis biofilm-related infections are a current concern within the medical community due to their high incidence and prevalence, particularly in patients with indwelling medical devices. Biofilm gene expression analysis by quantitative real-time PCR (qPCR) has been increasingly used to understand the role of biofilm formation in the pathogenesis of S. epidermidis infections....
چکیده سابقه و هدف: سرطان مری، ششمین عامل مرگ ناشی از سرطان در جهان است. شیوع سرطان مری در ایران بسیار بالاست. p53 یکی از شناخته شده ترین ژن های بازدارنده ی تومور است که در برابر آسیب های وارده به dna فعال می شود و هدف مهمی برای تحقیقات شناخته می شود. به دلیل اینکه تاکنون هیچ تحقیق و پژوهشی در مورد ژن p53 در بیماران مبتلا به سرطان مری با تکنیک real-time pcr در ایران انجام نگرفته است، ضرورت انجام...
Several techniques have been developed to screen mismatch repair (MMR) genes for deleterious mutations. Until now, two different techniques were required to screen for both point mutations and large rearrangements. For the first time, we propose a new approach, called ‘‘quantitative PCR (qPCR) high-resolution melting (HRM) curve analysis (qPCR-HRM),’’ which combines qPCR and HRM to obtain a rap...
BACKGROUND Reverse-transcriptase quantitative real-time polymerase chain reaction (RT-qPCR) has become the gold standard for the diagnosis of human enterovirus (EV) and parechovirus (HPeV) infections. The detection rate of RT-qPCR in different pediatric body specimens has not been compared prospectively in a multicentre study. OBJECTIVES This study compared the diagnostic detection rates of E...
INTRODUCTION An increasing number of studies have investigated microRNAs (miRNAs) as potential markers of diagnosis, treatment and prognosis. So far, agreement between studies has been minimal, which may in part be explained by intratumoral heterogeneity of miRNA expression. The aim of the present study was to assess the heterogeneity of a panel of selected miRNAs in rectal cancer, using two di...
