بررسی حساسیت و اختصاصیت روش high resolution melting analysis در شناسایی انواع جهش های مختلف ژن rb1
روش های متنوعی برای شناسایی جهش ها ابداع شده است که هریک از آنها دارای مزایا و معایب خاص خود هستند. یکی از روش هایی که اخیراً ابداع شده و در مطالعات مختلف به کارآیی بالای آن اشاره شده است روش high resolution melting analysis یا hrm است. در مطالعه حاضر برای اولین بار در ایران به منظور شناسایی جهش ها تمامی اگزون های ژن rb1 با استفاده از روش تعیین توالی بررسی شده است. در ادامه به منظور بررسی حساسیت...
Characterisation of Nanoparticle Structure by High Resolution Electron Microscopy
Whilst the use of microscopic techniques to determine the size distributions of nanoparticle samples is now well established, their characterisation challenges extend well beyond this. Here it is shown how high resolution electron microscopy can help meet these challenges. One of the key parameters is the determination of particle shape and structure in three dimensions. Here two approaches to ...
متن کاملStrategy for reliable strain measurement in InAs/GaAs materials from high-resolution Z- contrast STEM images
Geometric phase analysis (GPA), a fast and simple Fourier space method for strain analysis, can give useful information on accumulated strain and defect propagation in multiple layers of semiconductors, including quantum dot materials. In this work, GPA has been applied to high resolution Z-contrast scanning transmission electron microscopy (STEM) images. Strain maps determined from different g...
متن کاملQuantitative analysis of nanoparticle internalization in mammalian cells by high resolution X-ray microscopy
BACKGROUND Quantitative analysis of nanoparticle uptake at the cellular level is critical to nanomedicine procedures. In particular, it is required for a realistic evaluation of their effects. Unfortunately, quantitative measurements of nanoparticle uptake still pose a formidable technical challenge. We present here a method to tackle this problem and analyze the number of metal nanoparticles p...
متن کاملDetection of Microsatellite Instability by High-Resolution Melting Analysis in Colorectal Cancer
Background: Colorectal cancer (CRC) is the third most common cancer worldwide. microsatellite instability (MSI) is a molecular marker of a deficient mismatch repair system and happens in almost 15% of CRCs. Because of a wide frequency of MSI+ CRC in Iran compared to other parts of the world, the importance of screening for this type of cancer is highlighted. Methods: The most common MSI detecti...
