Objective. To evaluate the effect of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) on immunoparalysis as defined by a sustained decrease of HLA-DR expression on monocytes in patients with severe sepsis. Design. Prospective, non-randomised observational study. Setting. Two anaesthesiological intensive care units of a(More)
A two-step reverse-transcriptase-based polymerase chain reaction (PCR) with nested primer pairs was developed to amplify sensitive and specific cytokeratin-19 (CK-19) mRNA sequences from human breast cancer cells. No CK-19 pseudogene interference was seen. The larger DNA-derived amplification products could be clearly discriminated from mRNA-derived(More)
Several reverse transcriptase polymerase chain reaction (RT-PCR) assays have been described for the detection of circulating tumour cells in blood and bone marrow. Target mRNA sequences for this purpose are the cytokeratins (CK) 19 and 20, the carcinoembryonic antigen (CEA), and the prostate-specific antigen messages. In this study, we investigated(More)
LI-cadherin (Liver-Intestine cadherin) is a member of a subclass (7-D cadherins) within the cadherin superfamily. Although its cellular function as a cell-cell adhesion molecule has been demonstrated in cell culture studies, its physiological function still needs to be explored in the intact organism. After isolating the cDNA for mouse LI-cadherin, we(More)
The reverse transcription polymerase chain reaction (RT-PCR) amplification of cytokeratin 20 (CK20) mRNA is considered a promising candidate method for the detection of circulating tumour cells in bone marrow and peripheral blood of cancer patients. In this study we have investigated the diagnostic specificity of the CK20 mRNA detection in samples from(More)
Monoclonal B-cell lymphocytosis (MBL) and monoclonal gammopathy of undetermined significance (MGUS) result from clonal expansions of mature B or plasma cells. Here, we set out to determine the immunophenotypic/monoclonal immunoglobulin (M protein) features and co-prevalence of MBL and MGUS in a hospital-based cohort of 1909 non-hematooncological patients.(More)
Several reverse-transcriptase polymerase chain reaction (rtPCR) assays have been designed for the detection of disseminated cancer cells. The specificity of these discussed molecular approaches is controversial. Biological interference of the cytokeratin-20 and mammaglobin rtPCR assays has been investigated. Cell lines of different lineages and bone marrow(More)
We prospectively monitored the postmortem course of interleukin-1β (IL-1β), soluble interleukin-2 receptor (sIL-2R) and lipopolysaccharide binding protein (LBP) in septic and non-septic fatalities to evaluate their potential as biochemical postmortem markers of sepsis. Serum concentrations were determined by chemiluminescent immunometric assays. In both the(More)
A biomarker profile of high folate and vitamin B-12 and low plasma homocysteine concentrations reduces the risk of coronary heart disease (CHD) and may be linked to diet. The objectives of the present study were to identify a food pattern related to these biomarkers and to examine its association with CHD risk. Dietary patterns related to biomarker plasma(More)
The classic molecular biology methods like Northern or Southern blot analyse non-amplified DNA or RNA, but need large amounts of nucleic acids, in many instances from tissues or cells that are heterogeneous. In contrast, polymerase chain reaction (PCR)-based techniques allow us to obtain genetic information through the specific amplification of nucleic acid(More)
