background: tuberculosis is one of the infectious diseases worldwide that has resurgence by the aids epidemic and led to the rise of drug-resistant tuberculosis patients. thus, it seems essential to monitor the drug susceptibility in tuberculosis patients. the new high resolution melting (hrm) method is simple, rapid and inexpensive for detection of the mutations responsible for drug resistance...
PURPOSE To demonstrate the utility of high resolution 20 MHz ophthalmic ultrasound in serial follow-up of optic nerve head melanocytoma patients. METHODS This study is a retrospective review of 30 patients with melanocytoma of the optic nerve head studied with echography. All patients were evaluated with standard ophthalmic A-scan and B-scan ultrasonography and 10 (33%) underwent high-resolut...
A new two-dimensional, real-time, high resolution ultrasound imaging system is described. This system uses a linear array of ultrasound transducers to generate tomographic images of the heart in a circular sector format. Phased array techniques allow rapid steering of the ultrasound beam so that images are produced at the rate of 20 per second, or more, while maintaining a resolution of 2-4 mm ...
Background: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is one of the few techniques which can obtain cells and tissue from the liver and pancreas. However, the technique remains vulnerable to poor specimen quality and sampling error. Objectives: To evaluate the ability of a high-resolution microendoscope (HRME) to visualize the cellular and architectural features of normal an...
introduction: pulmonary involvement secondary to systemic sclerosis (ssc) is the major cause of morbidity and mortality in ssc patients. we designed this study to determine the correlation of important lung function parameters with lung high resolution ct (hrct) scan findings.materials and methods: thirty–two consecutive diffuse ssc patients with pulmonary fibrosis were enrolled in this cross-s...
سابقه و هدف: آنالیز hrm (high resolution melting) تکنیکی است که میزان کاهش فلورسنت را در طی فرایند شیب حرارتی ذوب dna در اثر خروج رنگ اندازه گیری می نماید. ژن stk11 یکی از پروتئین های خانواده سرین- ترئونین کیناز سلولی را رمز می نماید که تنظیم کننده قطبیت سلولی بوده و هم چنین به عنوان پروتئین مهار کننده تومور عمل می نماید. موتاسیون های ژرم لاین در این ژن همراه با سندروم peutz-jeghers واستعداد اب...
