Aunque la asociación entre linfomas y se ha descrito, presencia simultánea las 2 entidades dentro del mismo órgano es rara asocia Presentamos un caso aparición linfoma angioinmunoblástico linfonodo, además concurrente herpes virus (KSHV) Epste...

Gastric cancer (GC) is the fifth most common cancer in the world and accounts for 7% of the total cancer incidence. The prognosis of GC is dismal in Western countries due to late diagnosis: approximately 70% of the patients die within 5 years following initial diagnosis. Recently, integrative genomic analyses led to the proposal of a molecular classification of GC into four subtypes, i.e.,micro...

OBJECTIVES The aim of the present study was to assess the prevalence of Herpes Simplex virus, Epstein Barr virus and Human Papilloma virus -16 in oral lichen planus cases and to evaluate whether any clinical variant, histopathological or demographic feature correlates with these viruses. STUDY DESIGN The study was conducted on 65 cases. Viruses were detected immunohistochemically. We evaluate...

The development of drugs in the generic pharmaceutical industry is a highly competitive arena of companies vying for few drug products that are coming off patent. Companies that have been successful in this arena are those that have met or surpassed the critical timeline associated with trial formulation development, analytical method development, and submission batch manufacturing and testing....

The two regions of the Epstein-Barr virus genome carrying partially homologous clusters of short tandem repeats (DSL and DSR [duplicated sequences, left and right, respectively] ) are transcribed into polyadenylated RNA upon spontaneous or chemical induction of the lytic virus cycle. In Raji, an Epstein-Barr virus genome carrying a nonproducer cell line, transcription of DSL and DSR is only obs...

INTRODUCTION Epstein-Barr virus esophagitis in an immunocompetent host is a rare entity. It represents either primary infection or reactivation and is usually characterized by acute onset and extensive ulcerative involvement of the upper and middle third of the esophagus. CASE PRESENTATION A case of Epstein-Barr virus esophagitis in a 27-year-old woman with no immunosuppressive factors, and h...

A simple gel technique is described for the detection of large, covalently closed, circular DNA molecules in eucaryotic cells. The procedure is based on the electrophoretic technique of Eckhardt (T. Eckhardt, Plasmid 1:584-588, 1978) for detecting bacterial plasmids and has been modified for the detection of circular and linear extrachromosomal herpesvirus genomes in mammalian cells. Gentle lys...

Hairy cell leukemia (HCL) is a rare chronic B-cell malignancy that, according to modern classifications, is a subgroup of non-Hodgkin lymphomas (NHLs). A rapid increase in incidence of NHL has been reported in many countries. The reasons for this increase are largely unknown, but exposure to organochlorines has been suggested as a risk factor. Epstein-Barr virus is a human herpesvirus that has ...

Immunoglobulin A (IgA) antibodies to Epstein-Barr virus viral capsid antigen were assayed serially in 19 patients with infectious mononucleosis and in 38 controls. Seventy-four percent of infectious mononucleosis patients demonstrated IgA antibody, whereas this was found in 13% of controls. This antibody appeared early in infectious mononucleosis and was virtually gone 10 weeks after onset. Com...

Cytomegalovirus and Epstein-Barr virus infections remain one of the main concerns in the postoperative care of children with a liver transplantation. Most of the pediatric liver transplant recipients are seronegative for cytomegalovirus and/or Epstein-Barr virus at transplantation and this places them at marked risk for the development of cytomegalovirus/Epstein-Barr virus-related diseases. In ...
