The activity of natural killer cells was found to be deficient in 10 of 12 males with X-linked lymphoproliferative syndrome, a life-threatening proliferation of lymphocytes after infection by Epstein-Barr virus. The activity levels of natural killer cells from affected males were increased after treatment with interferon in vitro, but normal levels of killing were not obtained. Deficient activi...

The association between Epstein-Barr virus subtype, human leukocyte antigen class I alleles, and the development of posttransplantation lymphoproliferative disorder was examined in a group of 25 bone marrow transplant recipients. A highly statistically significant correlation was observed between the human leukocyte antigen B51 allele and development of posttransplantation lymphoproliferative d...

It was shown by Bishop that if Thurston's $K = 2$ conjecture holds for some planar domain, then Brennan's the Riemann map of domain as well. In this paper we show numerically original counterexample to $K=2$ given Epstein, Marden and Markovi\'{c} is not a conjecture.

A 9-year-old white boy developed a fatal primary Epstein-Barr virus (EBV) infection while receiving chemotherapy for acute lymphoblastic leukemia in remission. Histopathological findings at the height of the proliferative phase of the illness were compatible with a virally induced hemophagocytic syndrome. The infection spontaneously converted to complete aplasia of the bone marrow and lymph nod...

The four major Epstein-Barr virion envelope components were separated by column chromatography and reconstituted into artificial liposomes. These liposomes were tested for their ability to bind selectively to Epstein-Barr virus receptor-positive cells. Only when the two high-molecular-weight glycoproteins, VE1 and VE2, were present together was a stable binding complex formed. The addition of t...

Virus-nonproducer Raji cells, when induced to early antigen synthesis by 12-O-tetradecanoyl-phorbol-13-acetate and sodium butyrate, showed an increase in DNA polymerase activity. This enzyme has the characteristics of a typical Epstein-Barr virus DNA polymerase with regard to chromatographical pattern and biological properties: it is eluted from DEAE-cellulose at 0.08 M NaCl, has a high salt re...

Tumour tissue from 29 patients with primary brain lymphoma was reviewed to determine if there was an aetiological association between Epstein-Barr virus and polyclonal and monoclonal lymphoproliferations. The morphology and immunophenotype in 24 patients for whom paraffin wax embedded tissue was available were studied. A high grade pleomorphic tumour morphology with plasmacytoid features was se...

A post-transplant lymphoproliferative disorder (PTLD) is an uncommon but serious complication following solid-organ transplantation. The incidence varies, depending on the type of organ transplanted, the degree of immunosuppression, the number of episodes of acute rejection and a patient's immune status to Epstein-Barr virus. The incidence of PTLD is thought to be bimodal; cases in the first ye...

R.L. Epstein and E. Buitrago-Díaz aspire to present a vitally new approach to temporal logic, an approach based on the idea of absolute truth-values. They claim the existing approaches are confused and incoherent, and contain a significant number of nonsenses. The alleged problems are generated by truth-values being relativized to positions in time. The fundamental incoherence consists in some ...
