introduction: primary gastric lymphoma (pgl) is a rare tumor, whose differential diagnosis may become complicated without precise immunohistochemistry (ihc) and genetic analysis. case presentation: a 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise ihc and staging in another center. inappropriate ihc after surgery showed diffuse large b-cell lymphoma...
in this study, estimation of global and diffuse solar radiations of selected cities in nigeria was carried out to assess the feasibility of solar energy utilization. the results of this work show the variation of direct and diffuse component of solar radiation in summer and winter months. the contribution of diffuse solar radiation is high during the monsoon months whereas sky conditions are cl...
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...
purpose: suitable magnetic resonance imaging (mri) techniques from conventional to new devices can help physicians in diagnosis and follow up of multiple sclerosis (ms) patients. the aim of present research was to compare effectiveness of fluid attenuation inversion recovery (flair) sequence of conventional mri and diffuse weighted imaging (dwi) sequence as a new technique in detection of brain...
PURPOSE To determine the nature of hyaline membranes in different manifestations of diffuse alveolar damage, [pulmonary and extrapulmonary acute respiratory distress syndrome], and idiopathic [acute interstitial pneumonia]. MATERIALS AND METHODS Pulmonary specimens were obtained from 17 patients with acute respiratory distress syndrome and 9 patients with acute interstitial pneumonia. They we...
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...
