To test the possibility that individuals with and without plasma cholinesterase Cs isozyme have differences in neuromuscular sensitivity to succinylcholine chloride, we ~ramined the effects of succinylcholine in these two groups of patients. Sera from 491 adult patients were examined for presence of the plasma cholinesterase Cs isozyme by use o f electrophoresis with polyacrylamide ; 24 were posi-
Electronic portal imaging device (EPID) plays an important role in radiation therapy portal imaging, geometric and dosimetric verification. Consistent image quality and stable radiation response is necessary for proper utilization that requires routine quality assurance (QA). A commercial 'EPID QC' phantom weighing 3.8 kg with a dimension of 25 × 25 × 4.8 cm³ is used for EPID QA. This device ha...
دیواره مثانه شامل شبکه انبوهی از فیبرهای عضلانی صاف می باشد که از افزایش ناگهانی فشار مثانه که منجر به انقباض و نشت ادرار از مثانه قبل از پرشدن کامل آن می شود جلوگیری می کند و حدود ۵۰۰ سی سی ادرار را در خود جای می دهد. مجرای پیشابراه که بعنوان محل خروجی برای مثانه محسوب می شود شامل دو لایه عضله صاف و یک ناحیه تنگ شده عضلانی است که تحت کنترل ارادی می باشد و بعنوان اسفنکتر خارجی عمل می کند. هنگام...

Introduction: Proton magnetic resonance spectroscopy (MRS) is a well-known device for analyzing the biological fluids metabolically. Obtaining accurate and reliable information via MRS needs a homogeneous magnetic field in order to provide well-defined peaks and uniform water suppression. There are lots of reasons which can disturb the magnetic field homogeneity which can be corrected by a proc...
