Background: Breast cancer is one of the most common malignancies in the world, and early diagnosis of this cancer is a key factor in its treatment. This cancer is a multi-stage disease, in which viruses can play a role. EBV is known as an important factor in the development of some human cancers. Therefore, this study was conducted to determine the relationship between Epstein-Barr virus, EBV, ...
background: breast cancer is the malignancy in humans and other mammals. several risk factors are involved in their appearance such as higher hormone levels and obesity. identification of a mouse mammary tumor virus supports a viral etiology for breast tumors in animals. viruses have been implicated in the development of various cancers, but viral induction for formation breast cancer is contro...
The Enzygnost anti-Epstein-Barr virus enzyme-linked immunosorbent assay (ELISA) system, which is based on a defined antigen mixture and on detection of antibodies of the immunoglobulin G (IgG), IgM, and IgA classes, was evaluated for its reliability in diagnosing Epstein-Barr virus infections in childhood. With samples from 66 children, the Epstein-Barr virus status and the infection phase were...
conclusions the findings of the meta-epidemiological study support that ebv infection may increase the risk of breast cancer. nested case-control studies are required in the future. results a total of 20 case-control studies were selected, and the total numbers of subjects in the case and control groups were 1947 and 1010, respectively. the findings of this meta-analysis revealed that ebv infec...

 An elegant study reported dysmorphic cells and syncytia in deceased's lungs for COVID-19. The authors reasonably considered that most of these syncytia-forming were pneumocytes, as identified by specific biomarkers. However, cellular dysmorphism are pathological features common other respiratory infections caused different viruses, including human syncytial virus (HRSV) Epst...
introduction epstein-barr virus (ebv) infection can present with a variety of manifestation. case report here we present a case of a 7 year- old immunocompetent girl who came with acute abdominal pain , had echocardiographic evidence of myocardial dysfunction and finally was diagnosed as a case of serologically proven acute ebv infection. conclusion...
OBJECTIVE Clarify the frequency and the pathophysiological mechanisms of the rare manifestations of Epstein-Barr virus infection. SOURCES Original research studies published in English between 1985 and 2015 were selected through a computer-assisted literature search (PubMed and Scopus). Computer searches used combinations of key words relating to "EBV infections" and "atypical manifestation."...
the aim of this work was to see whether tamarin immunisation with recombinant vaccinia virus expressing epstein barr virus latent proteins could prime t cells which were, on activation, able to inhibit the outgrowth of epstein barr virus transformed cells in vitro. the vaccination appeared to be successful as all vaccinated tamarins developed vaccinia lesions. however, the vaccination protocol ...
BACKGROUND After acute infection of Epstein-Barr virus, Epstein-Barr virus-infected B cells survive but usually do not show clonal proliferation. However, Epstein-Barr virus-infected B cells occasionally acquire a proliferative capacity that provokes clonal lymphoproliferative disorders. We herein present a case with Epstein-Barr virus-infected CD30+ B cell and immunoglobulin G4+ plasmacytoid c...
background: colorectal cancer is one of the most common malignancies worldwide with more than one million new cases diagnosed each year . the aim of this study is to investigate the prevalence of herpes simplex virus and epstein-barr virus in patients with colorectal carcinomas and polyps in comparison with healthy subjects by using the polymerase chain reaction technique. methods: in this anal...
