background and objectives: epstein barr virus (ebv) is one of the members of herpesviridae family and a sub-category of gamma herpes virinae. ebv, which normally has cr2 or cd21 receptors on b-lymphocytes, has mutagenic features for them. the virus plays an important role in causing some malignant cancers. about 30% of the cases with non-hodgkin’s lymphoma are diffuse large b-cell lymphoma (dlb...

Epithelial-mesenchymal transition (EMT) is associated with tumor malignancy. The hedgehog-EMT pathway is preferentially activated in diffuse-type gastric cancer (GC) compared with intestinal-type GC; however, histological typing is currently the only method for distinguishing these two major types of GC. We compared the gene expression profiles of 12 bone marrow-derived mesenchymal stem cell cu...

The scattering from crystals can be divided into two parts: Bragg scattering and diffuse scattering. The analysis of Bragg diffraction data gives only information about the average structure of the crystal. The interpretation of diffuse scattering is in general a more difficult task. A recent approach of analysing diffuse scattering is based on the Reverse Monte Carlo (RMC) technique. This meth...

Diffuse traumatic brain injury refers to widespread pattern of injury throughout the brain caused by traumatic disruption of nerve cells, with particular injury to the axons [1]. There are four principal types of traumatic brain injury: diffuse vascular injury, diffuse axonal injury, hypoxic-ischemic encephalopathy and diffuse brain swelling [2]. Clinically, DAI is characterized by generalized ...

In this study, data were prospectively collected from 753 patients (111 children and 642 adults) with severe head injury and examined for evidence of diffuse brain swelling and its association with outcome. Diffuse brain swelling occurred approximately twice as often in children (aged 16 years or younger) as in adults. A high mortality rate (53%) was found in these children, which was three tim...
