The Light Cycler technique combines rapid in vitro amplification of DNA in glass capillaries with real-time species determination and quantification of DNA load. We have established a quantitative PCR protocol for two clinically important pathogens, Candida albicans and Aspergillus fumigatus. The sensitivity of the assay was comparable to those of(More)
In 1988 and 1989, thousands of harbor seals (Phoca vitulina) died in the North Sea from phocine distemper infection. The morphology of thyroid glands from 40 harbor seals found dead on the North Sea coastlines of Schleswig-Holstein, Federal Republic of Germany, during an epizootic of phocine distemper, was compared with the morphology of thyroid glands from(More)
Recent findings support the hypothesis that the CD34(+)-cell population in bone marrow and peripheral blood contains hematopoietic and endothelial progenitor and stem cells. In this study, we report that human AC133(+) cells from granulocyte colony-stimulating factor-mobilized peripheral blood have the capacity to differentiate into endothelial cells (ECs).(More)
PURPOSE About 50% of prostate cancers have TMPRSS2-ERG fusions with concurrent ERG overexpression. The aim of this study was to determine whether clinical differences exist between ERG-positive and ERG-negative cancers in surgically treated patients not exposed to antihormonal therapy. A secondary aim was to search for differences between these tumor(More)
PURPOSE The cell adhesion molecule CEACAM1 is involved in intercellular adhesion and subsequent signal transduction events in a number of epithelia. CEACAM1 downregulation has been demonstrated in colorectal and prostate carcinomas. This study sought to analyze whether its expression in malignant melanoma is associated with metastasis. PATIENTS AND(More)
Invasive candidiasis has become a major cause of morbidity and mortality in immunocompromised hosts. Here we describe a fast and reliable DNA extraction and PCR amplification method in combination with a slot blot hybridization assay. A genus-specific probe was designed that allowed to detect DNA from a broad range of Candida species and 3 other yeasts. In(More)
Five commercially available extraction kits and an in-house DNA extraction method for the release of DNA from Candida albicans and Aspergillus niger cells were assessed for sensitivity, purity, duration, and cost. All commercially available kits helped to shorten the duration of DNA extraction. However, the sensitivity varied from 1 to 1,000 fungal cells/ml(More)
Recruitment of polymorphonuclear neutrophils (PMNs) remains a paramount prerequisite in innate immune defense and a critical cofounder in inflammatory vascular disease. Neutrophil recruitment comprises a cascade of concerted events allowing for capture, adhesion and extravasation of the leukocyte. Whereas PMN rolling, binding, and diapedesis are well(More)
BACKGROUND Interactions of endothelial selectins with tumour cell glycoconjugates have been shown to have a major role in tumour cell dissemination in previous experiments. However, experiments validating this observation were limited in value, as 'metastases' in these experiments were artificially induced by i.v. injection rather than developed(More)
Since articular cartilage is subjected to varying loads in vivo and undergoes cyclic hydrostatic pressure during periods of loading, it is hypothesized that mimicking these in vivo conditions can enhance synthesis of important matrix components during cultivation in vitro. Thus, the influence of intermittent loading during redifferentiation of chondrocytes(More)
