ویروس آنفلوآنزا که عامل مولد یکی از بیماریهای حاد تنفسی می باشد در غشا خود واجد گلیکوپروتئین مهمی به نام همآگلوتینین است. این مولکول ضمن اینکه اصلی ترین آنتی ژن برای القا پاسخ ایمنی بر علیه ویروس است، همواره به عنوان مدل ایده آلی برای مطالعه فرآیندهای بیولوژیکی مهم از جمله گلیکوزیلاسیون مورد استفاده قرار گرفته است. گلیکوزیلاسیون ( به ویژه از نوع n) متداولترین تغییر ضمن یا پس از ترجمه ای پروتئین...
Detection of Helicobacter pylori in dental plaque by reverse transcription-polymerase chain reaction
The aim of the present study was to assess transcription Listeria monocytogenes key virulence genes, namely sigB, prfA, hly, plcA, plcB, inlA, inlB, inlC and inlJ during subsistence on surface tomato, cucumber carrot stored at 4, 10 30 °C for 0, 0.5, 6 24 h. Gene relative assessed through reverse transcription-quantitative polymerase chain reaction (RT-qPCR). results obtained, indicated that pl...
background and aims: accurate and rapid diagnosis is necessary for effective control and prevention of foot-and-mouth disease (fmd). in present study, was evaluated real time reverse transcription-polymerase chain reaction (rrt-pcr) assay along with diagnostic routine methods for the detection of all seven serotypes of fmd virus (fmdv), namely o, c, a, sat1, 2, 3 and asia 1 in biological sample...
CONTEXT Cutaneous melanoma presents significant morbidity and mortality. Nowadays, about 90% of them are diagnosed by clinical examination and most are localized melanomas. Sentinel node biopsy has brought about a new and interesting approach towards localized cutaneous melanoma. The meaning of micrometastases in sentinel nodes diagnosed by the reverse transcriptase-polymerase chain reaction is...
The aim of the present study was to investigate the mechanism of SGC7901 cell resistance to cisplatin (CDDP). SGC7901/CDDP cells were established by the long-term continuous exposure of SGC7901 cells to CDDP in stepwise concentration increments. The morphologies of the SGC7901/CDDP and SGC7901 cells were observed by microscopy. The expression levels of Survivin mRNA and protein in the SGC7901/C...
The determination of aflatoxin production ability and differentiation of aflatoxigenic strains can be assessed by monitoring the expression of one or several key genes using reverse transcription polymerase chain reaction (RT-PCR). We herein describe the methods for RNA induction, extraction, and quality determination, and the RT-PCR conditions used to evaluate the ability of a given Aspergillu...
results our study showed that the sensitivity and specificity of taqman real time pcr was 96% and 95% respectively. these values were 89% and 90, 38% and 100%, 6% and 100% for pcr, culture and microscopy, respectively. conclusions our study showed that sensitivity of taqman real time pcr was higher that pcr, culture and microscopy but specificity of culture and microscopy was more than pcr and ...
