The aim of this review is to present the similarities and differences between the latest guidelines for noninvasive diagnosis of hepatocelullar carcinoma (HCC) of American Association for the Study of Liver Diseases (AASLD), European Association for the Study of the Liver (EASL), Asian Pacific Association for the Study of the Liver (APASL), and Japanese Society of Hepatology. All the four guide...

Background: Ischemic stroke is a common cause of adult disability and death worldwide that leads to damage in neuronal networks and neurovascular units and ceasation of brain functions. In this study the effect of iron oxide nanoparticles and magnetic field on neurogenesis after ischemic reperfusion (IR) in rat model was evaluated. Methods: In this experimental study 50 male Wistar rats weighi...
