Geometric and densitometric properties of the Barr body of early and late phase II confluent human fibroblasts are analysed by the automated image analyser Quantimet 720 D. In cells with the same 2C DNA content, the state of condensation of the Barr body varies proportionally wih the state of condensation of the entire nucleus yielding a correlation between nuclear and Barr body area. In light ...

NPC-KT cl.S61, a subclone derived from an epithelial-nasopharyngeal carcinoma hybrid cell line (NPC-KT), showed cytopathic changes characteristic of herpesvirus replication, including formation of multinucleated giant cells and inclusion bodies, when Epstein-Barr virus replicative cycle was induced by 5-iodo-2'-deoxyuridine. Acyclovir (an inhibitor of herpesvirus DNA polymerase), Epstein-Barr v...

Attempts were made to superinfect epithelial explant cell cultures prepared from nasopharyngeal carcinomas with Epstein-Barr virus. Virus-specific markers were observed in such cultures 3 days after superinfection. In addition, expression of Epstein-Barr virus early antigens was observed in epithelial cell explant cultures treated with iododeoxyuridine. The results suggest that epithelial cells...

OBJECTIVES To determine whether the Epstein-Barr virus is present in synovial membranes and subcutaneous nodules of patients with rheumatoid arthritis. METHODS A sensitive in situ hybridisation technique was applied to tissue sections of 11 synovial membranes and five rheumatoid nodules. RESULTS Cells carrying the Epstein-Barr virus were not detected using EBER and BHLF1 oligonucleotides in...

Background Epstein-Barr virus (EBV) infects almost a large percent of the world’s adult population. Antibody prevalence rates reach 95% or higher among elderly individuals. Even in the pediatric population, Epstein Barr infection is common. Young children most likely acquire primary EBV infection from close contact that involves exchange of oral secretions via shared items such as toys, bottles...

    Abstract   Background: Multiple sclerosis (MS) is the most common autoimmune disease of central nervous system with destruction of myelin sheath mediated by auto reactive CD4+ T Lymphocytes. Because of the possible role of Epstein-Barr virus in etiology of MS and T cells immune response, the aim of this study was to evaluate anti-Epstein Barr virus antibodies as a marker of reactivity and p...

Epstein-Barr virus was observed by electron microscopy in human lympho­ blastoid cells derived from a rhabdomyosarcoma. Replication of virus particles was stimulated approximately 1 0 fold after treatment of the cells with either 5'-iododeoxyuridine or 5'-bromodeoxyuridine. The evidence supports the con­ cept that the entire Epstein-Barr virus genome persists in some cells of this type. The dat...

A new generalized unsupervised competitive learning rule is introduced for adaptive scalar quantization. The rule, called generalized Boundary Adaptation Rule (BARr), minimizes r-th power law distortion Dr in the high resolution case. It is shown by simulations that a fast version of BARr outperforms generalized Lloyd I in minimizing D1 (mean absolute error) and D2 (mean squared error) distorti...
