بررسی کارایی روشLAMP (Loop-mediated isothermal DNA amplification)
مقدمه:سالمونلاها از مهمترین باکتری های بیماری و عامل تیفوئید، باکتریمی، آنتروکولیت و سالمونلوز است که از عفونت های مشترک انسان و حیوانات می باشد. بیماریهای ناشی از این عامل یک معضل بزرگ بهداشتی در جهان به خصوص در کشورهای در حال توسعه از جمله کشور ما می باشد. بنابراین تشخیص سریع، دقیق و به موقع آن برای جلوگیری از اپیدمی و عوارض مخرب این باکتری ضروری به نظر می رسد. برای تشخیص سالمونلا روش های مخت...
متن کاملSPECIFIC AMPLIFICATION OF ASPERGILLUS FUMlGATUS DNA BY POLYMERASE CHAIN REACTION
Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus s...
متن کاملDriver Negligence vs. Odometer Miles: Rival Theories to Explain 12 Predictors of Auto Insurance Claims
This paper challenges accepted explanations for well-established correlations. The correlations allow insurers to assign cars to groups that predict accident and claim frequencies per 100 insured car years. Correlations with driver age and regional geography can be explained by variations in accident involvements per million miles established by engineering studies and are not considered in thi...
متن کاملDNA amplification moves on
whether fasting and changes in diet might be changing leptin levels, thus altering the function of T cells. The implication of this new work is that leptin drives the activity of pro-inflammatory, self-reactive T cells, and that starvation, which reduces leptin production, changes the pattern of cytokines generated and the disease-inducing potential of the T cells. So, the authors show that ins...
متن کاملFidelity of DNA polymerases in DNA amplification.
Denaturing gradient gel electrophoresis (DGGE) was used to separate and isolate the products of DNA amplification by polymerase chain reaction (PCR). The strategy permitted direct enumeration and identification of point mutations created by T4, modified T7, Klenow fragment of polymerase I, and Thermus aquaticus (Taq) DNA polymerases. Incorrectly synthesized sequences were separated from the wil...
