conclusions the viral load in patients who suffer from cchf has a direct significant correlation with disease severity. viral load above 8.6 × 105 copies/ml on the first day of admission is a predictor of severe cchf. background crimean-congo hemorrhagic fever (cchf) is an endemic disease in south eastern of iran, especially in sistan and baluchestan province. cchf is a potentially fatal diseas...

dear editor-in-chief we read with interest the study by khazaei et al. (1) in which the authors have nicely concluded that pcr is more sensitive test than ziehl-neelsen staining and histo-pathological examination for the diagnosis of tuberculosis (tb). they have rightly pointed to use pcr, selectively, in acidfast bacilli negative paucibacillary forms of tb. however, we intend to highlight few ...

Real-time PCR is the state-of-the-art technique to quantify nucleic acids for mutation detection, genotyping and chimerism analysis. Since its development in the 1990s, many different assay formats have been developed and the number of real-time PCR machines of different design is continuously increasing. This review provides a survey of the instruments and assay formats available and discusses...

The real-time polymerase chain reaction (RT-PCR), also called quantitative real-time polymerase chain reaction (QRT-PCR) or kinetic polymerase chain reaction (kPCR), is a technique used to simultaneously quantify and amplify a DNA molecule. It is used to determine whether a specific DNA sequence is present in the sample; and if it is present, the number of copies in the sample. It is the real-t...

background neuroblastoma is the most common extracranial malignant solid tumor in children under 5 years, and it is characterized by wide clinical and biological heterogeneity. n-myc oncogene amplification is considered to be one of the most important prognostic factors used to evaluate survival in these patients. objectives the aim of our study was to determine amplification of the n-myc oncog...

results 162 yeast species from 250 specimens were isolated in sabroud dextrose agar (sda) medium. 106 (65.4%) of them were germ tube formation positive, 86 (53%) chlamydoconidium formation positive and 101(62.4%) were pcr positive. yeast cells and mycelia were detected in the isolates on direct microscopic examination. c. albicans accounted for 66.04% of cases and 34% were non-c. albicans speci...
