Previously we described a PCR protocol for detecting the inversion in the factor VIII gene, which is a common cause of Hemophilia A. This PCR assay is challenging due to the size of the amplification (10-12 kb), the varying GC content (30%-80%) and the multiplex PCR products involved (four for carrier female). Efficient amplification of the four segments depends on three unusual modifications t...
مقدمه: سندرم long qt با طویل شدن qt در الکتروکاردیوگرام شناسایی می شود و می تواند منجر به سکته قلبی و مرگ ناگهانی شود. در اغلب موارد طویل شدن qt در اثر فاکتورهایی که منجر به طولانی شدن پتانسیل عمل می شود، ایجاد می گردد که عمدتا با تاخیر رپلاریزاسیون در فاز سوم همراه است. گزارش های بسیاری درباره ارتباط جهش های dna میتوکندریایی و بیماری های قلبی وجود دارد. در این مطالعه، هدف ما بررسی ژن های trna ...
We present a case of Pneumocystis pneumonia (diagnosis was based on imaging X-ray and CAT examinations, real-time PCR) in an HIV-infected patient with relapse four months later long lasting colonization as detected by the positive PCR results lack clinical symptoms during follow up after second course treatment trimethoprim/sulfamethoxazole. The wild-type P. jirovecii DHPS genotype identified a...
We report a rapid and efficient PCR-based rescue procedure for integrated recombinant retroviruses. Full-length proviral DNA is amplified by long-range PCR using a pair of primers derived from the long terminal repeats (LTR), and virus is regenerated by transfecting retrovirus-packaging cells with the PCR-derived provirus. The viral yield from the PCR product is similar to that from the retrovi...
Characterization of mutations of the PKD1 gene has been limited by the fact that three-fourths of this gene at its 5' end is homologous to sequences of at least three other genes on the same chromosome. We have therefore developed a method of long reverse transcription PCR for selective amplification of the entire coding sequence of the PKD1 gene from its mRNA. A PCR primer specific to the sequ...
BACKGROUND Locally advanced rectal cancer is usually treated with preoperative chemoradiation. After chemoradiation and surgery, 15-27% of the patients have no residual viable tumour at pathological examination, a pathological complete response (pCR). This study established whether patients with pCR have better long-term outcome than do those without pCR. METHODS In PubMed, Medline, and Embas...
Polymerase chain reaction (PCR) methodologies for detection of pathogens in environmental samples are currently available. However, positive amplification products for any set of primers only signal that the appropriate target nucleic acid sequences were present in the sample. The presence of the amplification products does not imply that the target organisms were viable. Here we show that PCR ...
