BACKGROUND Magnetic nanoparticles have been widely applied in recent years for biomedical applications. Signal intensity (SI) of magnetic resonance (MR) images depends on the concentration of nanoparticles. It is important to find the minimum concentration of iron oxide nanoparticles that produces maximum SI and determines the minimum injection dose for(More)
Ultrasound is one of the preferred modalities for evaluation of the parathyroid glands. This study was undertaken to determine the accuracy of high resolution ultrasound for secondary hyperparathyroidism in patients with chronic renal failure. From March 2008 to March 2009, ninety-one hemodialysis patients were examined by high resolution ultrasound (14(More)
This study was undertaken to compare correlation of conventional amniotic fluid index (AFI) as well as a new method with actual fluid volume on phantom. As an experimental study, 10 to 100 ml of water with 5ml intervals was injected to a rubber bladder as a uterus phantom containing a 15 week gestational age fetus.The largest radial diameter (perpendicular(More)
Amniotic fluid volume (AFV) is one of the important parameters in the assessment of fetal well-being. The ability of ultrasound measurements to represent the actual AFV is unproven. This study was undertaken to compare correlation of conventional amniotic fluid index (AFI) and radial amniotic fluid index (RAFI) as a new method with actual fluid volume on(More)
BACKGROUND Radiotherapy of the thorax often causes lung inflammation leading to fibrosis. OBJECTIVES The aim of this study was to investigate whether the use of glycyrrhizic acid (GLA) could improve the development of lung fibrosis in irradiated animals. MATERIALS AND METHODS Wistar rats were divided into four groups. Group A rats received thoracic(More)
To evaluate the ability of glycyrrhizic acid (GLA) to reduce the tumor necrosis factor α (TNF-α), release on messenger ribonucleic acid (mRNA) and protein production in the lungs using GLA in response to irradiation were studied. The animals were divided into four groups: No treatment (NT group), GLA treatment only (GLA group), irradiation only (XRT group),(More)
