abstract: ornithobacterium rhinotracheale (ort) has been identified as one of the emerging respiratory bacterial pathogens in turkey and chicken flocks. diagnosis of ort infection has been faced some difficulties in isolation and identification of the bacterium based on the biochemical properties. a reliable identification method that can be used in routine laboratory investigations is of impor...
In this short note, we present the results of a case study for monitoring the whole polymerase chain reaction (PCR) process (all steps) with a glass fiber fluorometer that was described in a former publication. To utilize this fluorometer, which was originally constructed for a PCR machine with three thermostating devices, a new thermostating device has been developed: the glass fiber matrix is...
Polymerase chain reaction (PCR) is an in vitro technique to synthesize large quantities of a given DNA molecule that separates the DNA into two complementary strands, uses a peltier heat pump to quickly heat and cool the DNA and uses the Taq polymerase for the synthesis of DNA. Taq is a bacterium that lives by volcanic sulfer jets at the bottom of the ocean where the temperature is very high. F...
dear editor-in-chief we read with interest the study by khazaei et al. (1) in which the authors have nicely concluded that pcr is more sensitive test than ziehl-neelsen staining and histo-pathological examination for the diagnosis of tuberculosis (tb). they have rightly pointed to use pcr, selectively, in acidfast bacilli negative paucibacillary forms of tb. however, we intend to highlight few ...
پروتئین های غیراختصاصی انتقال دهنده ی لیپید (nonspecific lipid transfer proteins) پروتئین های گیاهی هستند که بر اساس وزن مولکولی به دو گروه nsltp1 و nsltp2 تقسیم بندی می شوند. این پروتئین ها دربرابر عوامل فیزیکوشیمیایی مانند عوامل اکسید کننده و قابلیت اتصال به دارو و حمل آن را دارند. مولکول nsltp2 گیاه برنج ، پروتئینی است که به دلیل توانایی ذاتی عبور از غشا و اتصال به ترکیبات استروئیدی (از جمله...
giardia is one of the most common human parasites and causes a lengthly course of nonbacterial diarrhea. disease outbreaks due to giardia infection are often attributed to contaminated water supplies. a major problem associated with detection for this organism is the lack of sensitive and reliable methods. pcr has the potential to address many of the limitations.we have performed a pcr-based me...
A Review of Optimization Strategies and the Advantages Disadvantages using Polymerase Chain Reaction with Confronting Two-Pair primers (PCR-CTPP) in Genomics Studies
سرطان مری، یکی از تهاجمی¬ترین نوع سرطان دستگاه گوارش، شایع ترین علت مرگ و میر های مرتبط با سرطان درجهان است. بیشترین بروز سرطان مری در گروه سنی 70-50 سال رخ می دهد. همچنین فراوانی این بیماری در مردان بیشتر از زنان است. تحقیقات مختلف اثبات کرده است که آنکوژن astrocyte elevated gene-1 (aeg-1)، که همچنین mtdh و lyric نیز نامیده می¬شود) در چندین جنبه از پیشرفت تومور نقش اساسی بازی می¬کند. بیان یا ت...
