Prior studies have shown that patients with seropositive rheumatoid arthritis (RA) have an increased frequency of precipitating antibody against a nuclear antigen, the RA nuclear antigen, detected in human B lymphoblastoid cell lines infected by Epstein-Barr virus. The present investigations demonstrate that patients with seropositive RA also have specifically elevated titers of antibodies to a...

Immunoglobulin M (IgM) antibodies to Epstein-Barr virus were detected by using microtiter plates coated with anti-mu-chain antiserum and enzyme-labeled Epstein-Barr virus antigen. Optimum conditions for labeling were determined. The addition of unlabeled control antigen to the enzyme-labeled antigen was effective in reducing background reactions. Rheumatoid factor no longer interfered. Blocking...

La cytolyse marquée et la pancréatite retrouvées chez cette patiente, répondent les auteurs, bien que plus rares dans séries de littérature, ont toutefois été décrites le contexte d’une infection aiguë au virus d’Epstein-Barr.

form (McCracken & Barr, 1982, 1983; Barr & McCracken, 1983; Barr et al. 1983) it is probably appropriate to point out that we have confirmed the variability of nutrient intake by young cafeteria-fed animals and the complex dietary deficiencies which c v arise. Regretfully, we have been unable to find convincing evidence for the presence of the elusive DIT phenomenon in any of our experiments al...

Transcriptional inactivation of one X chromosome in mammalian female somatic cells leads to condensation of the inactive X chromosome into the heterochromatic sex chromatin, or Barr body. Little is known about the molecular composition and structure of the Barr body or the mechanisms leading to its formation in female nuclei. Because human sera from patients with autoimmune diseases often conta...

We report a patient with X-linked lymphoproliferative disease (XLP) who developed multiple central nervous system (CNS) manifestations of Epstein-Barr virus infection. XLP, or Duncan syndrome, is a rare inherited disorder characterized by the inability to clear Epstein-Barr virus infection. In addition to Epstein-Barr virus encephalitis, CNS lymphoproliferative disease, and lymphoma, this patie...

Epstein-Barr virus is an unusual pathogen in the aetiology of alveolitis. We describe a case of Epstein-Barr virus induced pneumonitis and its successful treatment with Aciclovir.

Healthcare professionals are generating a substantial volume of clinical data in narrative form. As healthcare providers are confronted with serious time constraints, they frequently use telegraphic phrases, domain-specific abbreviations and shorthand notes. Efficient clinical text processing tools need to cope with the recognition and resolution of abbreviations, a task that has been extensive...

Three exceptional cell lines have been tested for the presence of the Epstein-Barr virus genome by nucleic acid hybridization (complementary RNA.DNA) and Epstein-Barr virus-determined nuclear antigen tests. Two lines were derived from Swedish lymphoma cases and one from an African Burkitt-like lymphoma biopsy that was negative for Epstein-Barr virus DNA and the virus-determined nuclear antigen....
