The present study describes a real-time PCR approach with high resolution melting-curve (HRM) assay developed for the detection and differentiation of Schistosoma mansoni and S. haematobium in fecal and urine samples collected from rural Yemen. The samples were screened by microscopy and PCR for the Schistosoma species infection. A pair of degenerate primers were designed targeting partial regi...
Infections caused by non-tuberculous mycobacteria (NTM) is increasing wordwide. Due to the difference in treatment of NTM infections and tuberculosis, rapid species identification of mycobacterial clinical isolates is necessary for the effective management of mycobacterial diseases treatment and their control strategy. In this study, a cost-effective technique, real-time PCR coupled with high-r...
لیستریا مونوسایتوژنز یک پاتوژن غذایی مهم و عامل لیستریوزیس در انسان و حیوان است. از آنجاکه این باکتری می تواند شرایط سخت محیطی را تحمل نماید، به عنوان یک تهدید مهم در صنایع غذایی مطرح است. شیوع گاه به گاه لیستریوزیس به خصوص در اثر مصرف لبنیات در سال های اخیر سبب شده است که شناسایی و تشخیص آلودگی مواد غذایی به این باکتری مورد توجه قرار گیرد. در مطالعه حاضر دو روش mpn-pcr و real-time pcr با هدف ک...
سابقه و هدف: از عوامل ژنتیکی مهم در ابتلا به بیماری سیلیاک، حضور الل های hla-dq2 و hla-dq8 در افراد مبتلا می باشد. روش های مولکولی زیادی جهت تعیین این الل ها در دسترس می باشد اما این روش ها علاوه بر هزینه بالا، دارای مراحل متعددی هستند که استفاده از آن ها را دشوار کرده است، لذا هدف از این مطالعه، راه اندازی تکنیک ساده و سریع جهت تعیین الل های hla-dq در بیماران مبتلا به سیلیاک با روش sybr g reen...
A novel method for genotyping the clustered, regularly interspaced short-palindromic-repeat (CRISPR) locus of Campylobacter jejuni is described. Following real-time PCR, CRISPR products were subjected to high-resolution melt (HRM) analysis, a new technology that allows precise melt profile determination of amplicons. This investigation shows that the CRISPR HRM assay provides a powerful additio...
Human schistosomiasis caused by Schistosoma japonicum and Schistosoma mekongi is a chronic and debilitating helminthic disease still prevalent in several countries of Asia. Due to morphological similarities of cercariae and eggs of these 2 species, microscopic differentiation is difficult. High resolution melting (HRM) real-time PCR is developed as an alternative tool for the detection and diff...

PURPOSE The diagnosis of leptomeningeal metastases is usually confirmed by the finding of malignant cells by cytologic examination in the cerebrospinal fluid (CSF). More sensitive and specific cancer biomarkers may improve the detection of tumor cells in the CSF. Promoter methylation of the human telomerase reverse transcriptase (hTERT) gene characterizes most cancer cells. The aim of this stud...
High-resolution melting (HRM) allows single-nucleotide polymorphism (SNP) detection/typing using inexpensive generic heteroduplex-detecting double-stranded DNA (dsDNA) binding dyes. Until recently HRM has been a post-PCR process. With the LightCycler 480 System, however, the entire mutation screening process, including post-PCR analysis, can be performed using a single instrument. HRM assays we...
By detecting and quantitatively monitoring amplified DNA as PCR progresses, real-time PCR (quantitative or qPCR) instruments provide a robust approach for gene expression, genotyping, copy number variation, mutation screening, and methylation analysis. Data quality and reproducibility are governed by how robust a real-time PCR instrument’s thermal and optical systems are, with precise thermal c...
