Background and Aims: Epstein-Barr virus (EBV) infection is very common in the population. Virus belongs to the family Herpesviridae, whose representatives are characterized by the ability to cause the human body latent persistent infections. The goal of this study was to assess EBV infection frequency using PCR method in samples from inflammatory eye disease, in comparison with EBV presence in ...
Introduction: Proton radiotherapy is the one of advanced teletherapy methods. The protons deposit their maximum energy in a position called Bragg peak. Therefore, for treatment of cancer, the tumor should be placed at the Bragg peak or SOBP. The scattered photons and neutrons is a challenge in proton radiotherapy. The aim of this study is calculation of absorbed dose from scatt...
Background: Recent studies in eye plaque brachytherapy have shown a considerable difference between the dosimetric results using water phantom and a model of human eye containing realistic materials. In spite of this fact, there is a lack of simulation studies based on such a model in proton therapy literatures. In the presented work, the effect of utilizing an eye model with ocular media on pr...
Although a variety of treatments have been developed over the past decade to treat post-traumatic stress disorder (PTSD), one of the most effective psychological treatments to improve its symptoms is eye movement desensitization and reprocessing (EMDR).
