introduction quantitative susceptibility mapping (qsm) is a new contrast mechanism in magnetic resonance imaging (mri). the images produced by the qsm enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. these nuclei are targets in many clinical applications and therefore their easy localization is a must. in this study, we aimed to i...

abstract the aim of this study was threefold: (1) to investigate the relationship between knowledge of semantic prosody and efl learners general language proficiency; (2) to examine the relationship between qualitative as well as quantitative knowledge of words, and (3) to compare the performance of efl learner on receptive and productive measures of semantic prosody. the study is based on a...

Background: Hepatitis B surface antigen (HBsAg) is one of the main proteins of HBV envelop and its serum quantitative measurement is the most common quantitative test for monitoring the progress of Chronic Hepatitis B. Although measurement of serum HBV DNA copy number is a gold standard method for displaying viral load, the test is relatively expensive and it is not readily available everywhere...
