distribution of infectious hematopoietic necrosis (ihn) was studied in five major provinces producing rainbow trout(oncorhynchus mykiss)fry in iran by indirect fluorescence antibody ifatand nested-rt-pcr techniques. also the effect of time duration was examined on some positive samples after 8 months post sampling. samples of kidney, liver and spleen of rainbow trout fries collected from 27 tro...
تعداد 140 نمونه خون کامل (از شهرهای بندرعباس، کامیاران، پیرانشهر، پلدشت و ماکو، لاهیجان، قروه و بیله سوار از هرکدام 20 نمونه ی خون گوسفند و بز به تعداد مساوی از هر دو جنس) به وسیله ونوجکت به میزان 5-10 میلی لیتر همراه با edta از گوسفند و بز برخی مناطق مرزی ایران بطور تصادفی اخذ شده و در مجاورت یخ به آزمایشگاه ارسال می گردد. هدف از انتخاب نقاط ذکر شده، وجود نشانه های غیر اختصاصی از بیماری زبان آ...
The development of a rhinovirus (RV)-RNA-specific reverse transcription (RT)-PCR assay is complicated by the close homology between the RV and enterovirus (EV) genomes in the highly conserved 5'-noncoding region, which is chosen for primer design in most RT-PCR assays. We have developed a sensitive, rapid, and RV-specific nested RT-PCR assay and have used it to test nasopharyngeal aspirates fro...
We report a nested reverse transcription-polymerase chain reaction (RT-PCR) assay for hantavirus using primers selected to match high homology regions of hantavirus genomes detected from the whole blood of hantavirus cardiopulmonary syndrome (HCPS) patients from Brazil, also including the N gene nucleotide sequence of Araraquara virus. Hantavirus genomes were detected in eight out of nine blood...
PURPOSE The detection of disseminated occult breast cancer cells in peripheral blood and bone marrow is associated with poor prognosis. Since a high proportion of these cells express the HER-2 receptor, we evaluated the effectiveness of the anti-HER-2 antibody trastuzumab (Herceptin) administration to eliminate them. EXPERIMENTAL DESIGN Thirty patients with prior chemotherapy exposure were re...
Water samples were concentrated by the modified adsorption-elution technique followed by speedVac reconcentration of the filter eluates. Reverse transcriptase-nested polymerase chain reaction (RT-nested PCR) was used to detect rotavirus RNA in concentrates of the water. The detection limit of the rotavirus determined by RT-nested PCR alone was about 1.67 plaque forming units (PFU) per RT-PCR as...
We evaluated the use of an integrated cell culture-reverse transcription-PCR (ICC-RT-PCR) procedure coupled with nested PCR to detect human astroviruses, enteroviruses, and adenovirus types 40 and 41 in surface water samples that were collected and evaluated by using the Information Collection Rule (ICR) method. The results obtained with the ICC-RT-PCR-nested PCR method were compared to the res...
Accurate staging is an important issue in managing patients with prostate cancer. Current staging modalities are poor predictors for locally advanced disease. In the present study, we investigated the role of a peripheral blood-based, nested reverse transcription-PCR (RT-PCR) for prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSM) in prostate cancer staging. Our nested ...
