background and objectives: epstein barr virus (ebv) is one of the members of herpesviridae family and a sub-category of gamma herpes virinae. ebv, which normally has cr2 or cd21 receptors on b-lymphocytes, has mutagenic features for them. the virus plays an important role in causing some malignant cancers. about 30% of the cases with non-hodgkin’s lymphoma are diffuse large b-cell lymphoma (dlb...
Recurrent gene fusions between the genes TMPRSS2 and ERG have been described in prostate cancer (PCa) and are found in 27% to 79% of radical prostatectomy. This fusion transcription results in ERG overexpression, which can be detected by immunohistochemistry (IHC) and provide a potential diagnostic marker for PCa. Three tissue microarrays (TMAs) containing samples from 98 patients with PCa and ...
The immunological response in the regional lymph nodes (LN) of gastric cancer patients who had metastasis was studied by investigating both the degree of metastasis and the maturation status of dendritic cells (DCs). A total of 732 LNs was obtained from 29 gastric cancer patients, including 25 patients whose LNs were pathological metastasis-negative and 4 patients with metastasis-positive LNs. ...

Two techniques performed on skin biopsy samples (ear notches), immunohistochemistry (IHC) and antigen-capture ELISA (AgELISA), were compared for detection of bovine viral diarrhea virus (BVDV) persistent infection (PI) in 559 Angus calves between the ages of 1 and 5 months. The calves also were tested for BVDV infection using virus isolation (VI) and reverse transcription (RT)-PCR on buffy coat...
Objetivo. Revelar adenovirus (AdV) que causan pneumonía en ovejas y examinar cambios patológicos los ganglios linfáticos pulmonares mediastínicos de muestras positivas para infectadas forma natural. Material métodos. Se examinaron macroscópicamente 1459 pulmones se detectaron lesiones 88 (6.03%) estas. Las secciones tejido parafinadas estos especímenes con métodos inmunohistoquímicos (IHC) e in...
The variation and heterogeneity of conventional immunohistochemistry (IHC) or in situ hybridization (ISH) techniques for measuring HER2 has long been pointed out, the method testing discussed selection appropriate treatment. Therefore, we compared expression RT-PCR using OncotypeDX have correlation with IHC, evaluated as a prognostic factor HER2-negative early breast cancer. ER+/HER2- patients ...
INTRODUCTION Detection of anaplastic lymphoma kinase (ALK)-gene rearrangements in non-small-cell lung cancer (NSCLC) is mainly performed by fluorescence in-situ hybridization (FISH). The question was raised if FISH might be replaced by immunohistochemistry (IHC) in a reliable and reproducible manner across different laboratories. METHODS After calibration of the staining instruments and train...
The use of formalin-fixed paraffin-embedded (FFPE) tissues for HPV DNA detection by PCR from biopsy materials is not entirely clear in retrospective studies. The aim of our study was to evaluate the usefulness and efficiency of FFPE tissues from laryngeal cancer (LSCC) in HPV detection by immunohistochemistry reaction (IHC) and PCR-DNA enzyme immunoassay method (PCR/DEIA) and to compare with HP...
