The KRAS mutation test is recommended that it may determine which patients with advanced colorectal or lung cancer are eligible for antiEGFR targeted therapies. Traditional molecular techniques such as polymerase chain reaction (PCR) combined direct sequencing are limited by the difficulty of obtaining patients’ cancer tissues for analysis. Finding an alternative method to detect KRAS gene muta...

conclusions in conclusion, occult hbv was found in 36% of patients with negative results for hbsag, but positive results for hcv. detection of hbv-dna in both pbmcs and plasma together in comparison with plasma alone provided more true identification of obi.the svr rate was significantly higher in coinfected patients than mono-infected ones. background occult hepatitis b virus (hbv) infection (...

Human cytomegalovirus (HCMV) DNA quantitation in whole blood (WB) by real-time or quantitative polymerase chain reaction (qPCR) is a highly sensitive and reproducible diagnostic procedure for monitoring HCMV DNAemia (DNAemia the detection of samples plasma, blood, isolated peripheral leukocytes buffy-coat specimens) patients. We provided comparative analysis extraction performance two different...

Compartmental differences in human immunodeficiency virus type 1 (HIV-1) between the gut and peripheral blood and within the gut were examined. Biopsy specimens from the colon and ileum and peripheral blood samples were collected from chronically HIV-1-infected individuals. HIV-1 envelope sequences were examined from cell-associated DNA and RNA and virion RNA. Phylogenetic analysis revealed no ...

Peripheral blood stem cells (PBSCs) are being used as an alternative to autologous marrow rescue for hematopoietic reconstitution after high-dose chemotherapy in patients with neuroblastoma and other solid malignancies. Use of PBSCs is preferred by some because of the belief that there is less risk of tumor contamination. Because tumor stem cell contamination is thought to be one contributing c...

BACKGROUND The purpose of this study was to validate B7-H3 as a new cancer-specific endothelial marker in clear cell renal cell carcinoma. METHODS B7-H3 expression patterns were compared between cancer and paired adjacent normal renal parenchyma by immunohistochemistry in paraffin-embedded specimens from 200 consecutive patients with clear cell renal cell carcinoma from January to December 20...

BACKGROUND The altered composition of immune cells in peripheral blood has been reported to be associated with cancer patient survival. However, analysis of the composition of peripheral immune cells are often limited in retrospective survival studies employing banked blood specimens with long-term follow-up because the application of flow cytometry to such specimens is problematic. The aim of ...

Mycosis fungicides (MF), on extremely rare occasions, can be associated with vesiculobullous eruptions. We describe a 74-year-old man with previous documented histopathologic diagnosis of poikilodermic type of MF who recently developed some flaccid acral bullae on erythemoatous MF plaque and normal skin. Histopathology and direct immunoflourscence studies revealed extensive lichenoid chan...
