background: it has been suggested that malfunction of immune system may cause testicular cancer. recently, our understanding of innate immune system has been expanded, by discovery of “toll- like receptors” (tlrs). some studies have shown that polymorphisms of tlr2 and 4 can effect on the risk of cancer. also, the role of tlrs 3and 9 have been shown in apoptosis of cancer cells and metastasis i...
Cloned pigs generated by somatic cell nuclear transfer (SCNT) show a greater ratio of early abortion during mid-gestation than normal controls. X-linked genes have been demonstrated to be important for the development of cloned embryos. To determine the relationship between the expression of X-linked genes and abortion of cloned porcine fetuses, the expression of X-linked genes were investigate...
Background: There is no reliable serum marker available to monitor incipient pancreas or islet-cell rejection. We tested the hypothesis that quantification of donorspecific genomic DNA in serum (from tissue damage) can serve as a marker of rejection. Methods: Using a recently developed panel of HLAspecific quantitative PCR assays (Q-PCR), we tested 158 sera from 42 pancreas-kidney transplant re...
abstract- today, the authenticity of meat products with less costly and desirable species has increased. therefore and considering religious, economicalor public health concerns, proper actions should be taken to prevent such frauds. in this study, real time pcr assay was applied for rapid, sensitive and specific identification and quantification of chicken tissue in meat products. specific pri...
We present the first published case of Coxiella burnetii prosthetic joint infection. Diagnosis was established with PCR and culture of periprosthetic tissue and synovial fluid (and serology). A novel PCR assay is described herein. Q fever should be considered in patients with prosthetic joint infection without an identified pathogen.
Contamination of an in-house diagnostic real-time PCR for Q fever was traced back to a commercially obtained PCR Master Mix. It was established that this Master Mix contained DNA from Coxiella burnetii, probably as a result of the use of compounds of animal origin such as bovine serum albumin.
The use of a PCR method to investigate the fate of liberated Q(beta) coliphage RNA in wastewater suggests that a positive PCR result indicates the recent presence of potentially viable virus in the sample and therefore increases the public health significance of the result.
در ایجاد تومورها علاوه بر تغییرات ژنتیکی، تغییرات اپی ژنتیکی نیز دخیل هستند. مهمترین تغییرات اپی ژنتیکی شامل تغییر در متیلاسیونdna ، مدیفیکاسیون هیستون ها، تغییر وضیعت کروماتین و الگوهای تنظیمی micro rnaها بوده که با تومورزایی مرتبط می باشند. علم اپی ژنتیک به مطالعه ی تغییرات ارثی برگشت پذیر در عملکرد و بیان ژن ها، بدون تغییر در توالی نوکلئوتیدی آن ها می-پردازد. این تغییرات اصلی، dna را متاثر ن...
results in a total of 40 sporadic prostate cancer and 80 benign prostatic hyperplasia cases, no xmrv was detected by real-time pcr and nested-pcr. rnase l r462q polymorphism analysis reveals that although there was an increase in the risk of prostate cancer correlated with the q/q allele of rnase l at position 462, the frequencies of the rnase l r462q alleles were not statistically significant ...
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...
